Yet in countries like Ghana and Sierra Leone, there remains a critical gap in understanding the behavioral patterns and underlying factors driving this trend. Methods We retrieved secondary data from a public sphere collected using a cross-sectional study design. Overall, 12,281 students in grades associated with 11-18 year olds were selected using stratified two-stage cluster sampling. Descriptive statistics estimated smoking prevalence by age, sex, school grade, country, and survey year. Multivariate logistic regression models were used to determine associations between socio-demographic, behavioural, tobacco policy factors and current Shisha smoking. Adjusted odds ratios and their 95% confidence intervals are reported. Results The overall prevalence of current shisha smoking was 7.2% (7.8% males and 6.6% of females). The prevalence was slightly higher in Sierra Leone (7.69%, 95% CI: 7.05-8.33) than Ghana (6.58%, 95% CI: 5.94-7.23). Adolescents who did not support banning tobacco sales to minors had higher shisha use (7.96%, 95% CI: 7.34-8.57) than their counterparts (6.01%, 95% CI: 5.34-6.67). Participants who smoked cigarettes, were more likely to smoke shisha compared to those who did not smoke (AOR = 9.86; 95% CI: 7.84–12.38; p < 0.001). Conclusion Shisha smoking among school-going adolescents in Ghana and Sierra Leone reviewed emerging patterns suggesting early initiation and strong association with cigarette use. There is a need for stronger enforcement of tobacco control policies, targeting poly-tobacco use control and factors influencing early initiation. These findings provide valuable insight to inform tobacco control. Clinical trial number: not applicable Shisha Adolescents Tobacco Control Ghana Sierra Leone Figures Figure 1 INTRODUCTION Shisha, also known as waterpipe or hookah, is gaining popularity around the world, especially among young people ( 1 , 2 ). In contrast to cigarette smoking, which has been declining in many countries due to strong tobacco control measures, shisha is often and mistakenly seen as a safer alternative ( 3 , 4 ). This misconception has contributed to widespread use ranging from cafés in Europe and the Middle East to social gatherings in Asia and the Americas ( 5 – 7 ). As a result, global health experts are increasingly worried about the long-term impact of shisha smoking on public health ( 8 ). In Africa, shisha use has been rising steadily ( 9 , 10 ). Many young people are drawn to it because of the flavored tobacco and the social atmosphere around shisha smoking ( 11 , 12 ). Unfortunately, awareness of its health risks is still low. Studies have shown that shisha exposes users to harmful levels of nicotine, carbon monoxide, and cancer-causing substances ( 13 , 14 ). Despite the growing concerns, shisha lounges remain prevalent in many African cities, where tobacco control policies are either weak or inadequately enforced ( 15 ). Countries such as Ghana and Sierra Leone are experiencing similar trends ( 16 , 17 ). Young people in these countries are increasingly experimenting with shisha at early ages, often under peer influence and exposed to environments where tobacco advertising is not strictly regulated ( 17 , 18 ). Education efforts through schools and community programs are frequently under resourced to educate youths about these dangers ( 12 ). Although, policies restricting tobacco sales to minors and banning smoking in public places exist, their enforcement is inconsistent, allowing the habit to spread ( 19 ). While studies have been conducted on shisha smoking among adolescents in Africa, we are not aware of a study that analyzed pooled data from two countries. The aim of this study is to examine the prevalence and predictors of shisha smoking among school-going adolescents in Ghana and Sierra Leone. The findings from this study will provide evidence that can guide targeted interventions, strengthen existing policies, and help reduce the rising burden of tobacco-related harm in these countries and across Africa. METHODS Data Source This study used secondary data from the Global Tobacco Youth Surveys (GTYS) collected in 2017. The analysis focused on data from two West African countries: Ghana and Sierra Leone. The GYTS is a school based survey of students, in grades 7 to 9, aged 11 to 18 years. It is designed to produce a cross sectional national representative sample. The GYTS methodology for the sampling framework, selection of schools and classes, and data processing is standardized. The survey uses a standard questionnaire with core questions on tobacco use and key tobacco control variables and allows adaption to the needs of a particular country. All participants provided informed consent with their anonymity preserved through the use of unique identifiers instead of personal information. In addition, each country obtains ethical approval from the relevant authorities, ensuring compliance with local and international ethical standards. A more detailed description of the overall objectives and methodology of the GYTS are available elsewhere (20). The sample size and the schools are determined using a standard procedure and software developed by the Center for Disease Control and Prevention (CDC) upon receiving the sampling frame from the GYTS research coordinators. The actual sample size and its computation was not available, however, a minimum sample size of 1500 students, 50% of whom are female is required for the GYTS (20). A total of 12,281 school-going adolescents from Ghana (46%) and Sierra Leone (54%) were surveyed independently in the two countries in 2017. Records with missing data on current shisha smoking status were excluded to ensure accurate analysis. Dependent variable The primary outcome variable of interest was current shisha smoking that was generated from the question, “During the past 30 days (one month), on how many days did you smoke shisha?” with response options: 0, 1 or 2, 3 to 5, 6 to 9, 10 to 19, 20 to 29, all 30 days. Participants who smoked shisha at least once (Yes) in the preceding 30 days were classified as current shisha smokers, while those who did not (No) were classified as non-current shisha smokers. Independent variables Socio-demographic factors These were: age (≥11, 12, 13, 14, 15, 16, ≤18 years), sex (male and female) and grade (seven, eight, nine, ten, eleven and twelve). Behavioral and tobacco marketing factors Participants were asked, “During the last 30 days, have you ever tried smoking cigarettes?” Students who answered “Yes” were classified as cigarette smokers otherwise they were not. Participants who responded “Yes” to the question, “During the past 30 days, did you see any advertisements or promotions for shisha on TV, the internet or social media (Facebook, Twitter, Instagram, TikTok or YouTube) or any public place?” were classified as having been exposed to tobacco marketing. Curriculum factors Students were asked, “During the past 12 months, were you taught in any of your classes at school about the dangers of smoking shisha?” Students’ answers to this question were categorized as Yes or No. Policy factors This variable had two questions to which the students responded Yes/No; 1) “Are you in favour of banning smoking in public?” 2) “Do you think the sale of shisha or other smoked tobacco products to minors (under 18) should be banned?” Statistical Analysis Descriptive statistics were used to obtain numbers and percentages of current shisha smokers and non-smokers by their socio-demographic characteristics, behavioral and policy factors (21). The Chi-square test of association was utilized to determine associations between various factors and current shisha smoking status. Additionally, univariate and multivariate logistic regression models were used to examine the associations between factors that may influence shisha smoking among school-going adolescents in Ghana and Sierra Leone (22). Variables that were found to be significantly associated (p<0.05) with current shisha smoking status in the univariate analyses were included in the multivariate models. Stepwise model selection with Akaike Information Criterion (AIC) was applied to identify the most parsimonious model while retaining age and sex in the model due to their known confounding effects. Adjusted odds ratios (aORs) with 95% confidence intervals and p-values were reported and used as measures of magnitude of associations. Age, gender, ever tried smoking cigarettes, taught in class about the dangers of smoking were controlled for in the full model. To visualize the relationship between age and the probability of current shisha smoking, predicted probabilities were computed from the final adjusted model. Using Bayesian simulations from the model’s posterior distribution (1,000 simulations), we estimated mean predicted probabilities and 95% credible intervals by age and sex. These predictions were plotted to illustrate risk patterns across adolescent age groups. All analyses were conducted using R (version 4.5.0). Ethical Considerations Ethical approval was obtained from the University of Zambia Biomedical Research Ethics Committee (Ref. No.7265-2025) and the National Health Research Authority of Zambia (Ref. No: NHRA-2899/14/11/2025), in compliance with national research guidelines. Access to the anonymized GYTS datasets was granted by the WHO through the NCD Microdata Repository. As the study involved no direct contact with participants and used de identified data, no additional consent was required. The data for this research were accessed between 1 st April 2025 and 31 st December 2025. The authors had no access to information that could identify individual participants during or after data collection. RESULTS Characteristics of study participants The study included 12,281 school-going adolescents from Ghana (46%) and Sierra Leone (54%), surveyed independently in the two countries in 2017. The overall sample for the two countries was nearly evenly split by sex, with 53% female and 47% male. Age distribution showed most participants were between 13 and 15 years old, representing over 70% of the sample. School grade levels ranged from 7 to 12, with the largest groups in grades 9 and 10. These demographic details provide a broad overall picture of the youth population surveyed in two West African countries (Table 1). The overall prevalence of current shisha smoking among the youth was 7.2%. The prevalence of shisha smoking was significantly higher in Sierra Leone (7.69%, 95% CI: 7.05-8.33) than Ghana (6.58%, 95% CI: 5.94-7.23) (Table 1). Current cigarette smokers had a much higher shisha smoking prevalence (41.47%, 95% CI: 36.52-46.42) compared to non-smokers (6.08%, 95% CI: 5.65-6.51), indicating a strong association between cigarette and shisha use. Age-specific prevalence showed notable high rate of shisha use among youngest group (age 11), at 20.7%. Prevalence was lower ranging from 5.0% to 7.0% among those aged 13-14, and 7.5% among those aged 15 to 17. Males reported significantly higher prevalence (7.84%, 95% CI: 7.15-8.54) compared to females (6.60%, 95% CI: 6.00-7.21). Shisha smoking prevalence varied by school grade and attitudes toward tobacco control policies. Overall grade 7 students had a high prevalence (17.33%, 95% CI: 14.10-20.57), while older grades showed lower but steady rates (5.0% - 8.0%). Youth who did not support banning tobacco sales to minors had higher prevalence of shisha use (7.96%, 95% CI: 7.34-8.57) than those who supported such bans (6.01%, 95% CI: 5.34-6.67). Similarly, those opposing bans on smoking in public had extremely high prevalence (46.75%, 95% CI: 35.61-57.9) compared to (6.93%, 6.48-7.38) among supporters. These findings show how attitudes towards tobacco policies relate closely to actual tobacco use among young people.

After adjusting for other factors, age groups 13 to 17 had significantly lower odds of shisha smoking compared to age 11, with adjusted odds ratios (aOR) ranging from 0.30 (95% CI: 0.21–0.45, p < 0.001) for age-group 14 to 0.43 (95% CI: 0.29–0.64, p < 0.001) for age-group 16. Age-group 12 showed no significant difference after adjustment (aOR = 0.88; 95% CI: 0.53–1.46; p = 0.631). Males had slightly higher odds than females, but this was not statistically significant (aOR = 1.07; 95% CI: 0.93–1.24; p = 0.364). Living in Sierra Leone was associated with 74% higher odds of shisha smoking compared to living in Ghana (aOR = 1.74; 95% CI: 1.42–2.13; p < 0.001). The most significant factor associated with shisha use was current cigarette smoking, with smokers having nearly ten times the odds of using shisha compared to non-smokers (aOR = 9.86; 95% CI: 7.84–12.38; p < 0.001). Conversely, support for banning tobacco sales to minors was protective, reducing the odds of shisha smoking by 52.0% (aOR = 0.48; 95% CI: 0.39–0.58; p < 0.001). Support for bans on smoking in public places showed an even stronger protective effect, lowering odds by 90% (aOR = 0.10; 95% CI: 0.06–0.17; p < 0.001).

For example, crude ORs for age groups 13 to 17 were even lower (0.21–0.32) than adjusted, suggesting confounding factors raised odds somewhat after adjustment. Crude OR for current smokers was 10.94 (95% CI: 8.79–13.58; p < 0.001), close to the adjusted estimate. Country effect was smaller but still significant in crude (OR = 1.18; 95% CI: 1.03–1.36; p = 0.017). Support for tobacco bans showed weaker protective effects in crude models (OR 0.74 for sales ban; OR 0.08 for public ban) but remained highly significant. Overall, the analysis highlights age, smoking status, country, and tobacco policy attitudes as key independent factors shaping shisha use among youth in these countries. The predicted probability of current shisha smoking among students varied across ages 11 to 17 as shown in Figure 1. The probability increased gradually from age 11 years until it peaked at 15 before slightly declining at ages 16 and 17 but it was still higher than in the younger age category. This suggests that mid-adolescence represents a crucial time for shisha initiation, with the risk increasing gradually from early to mid-adolescence and continuing into late adolescent years. These findings review the importance of targeting tobacco control activities in early adolescence to prevent an increase in shisha use as adolescents grow. DISCUSSION This study estimates the prevalence and predictors of shisha smoking among school going adolescents in Ghana and Sierra Leone in 2017. Spatially, the study’s data were derived from two distinct countries with different cultural and regulatory environments, offering important regional insights. Sierra Leone accounted for a slightly larger portion of the sample than Ghana, which may influence the patterns observed. These geographic differences, combined with demographic and behavioral data, highlight areas where tobacco control efforts could be strengthened, especially regarding youth perceptions and policy awareness across West Africa. The overall prevalence of current shisha smoking among adolescents in Ghana and Sierra Leone was 7.2%. Shisha smoking was significantly higher in Sierra Leone compared to Ghana, highlighting important regional differences. Current cigarette smokers were nearly ten times more likely to use shisha. Interestingly, adolescents aged 13 to 17 had significantly lower odds of smoking shisha compared to the younger group aged 11, suggesting early initiation may be a critical factor. Students who saw smoking advertisements were more likely to smoke as compared to those who did not. Surprisingly, adolescents who were taught in class about the effects of tobacco smoking reported a higher prevalence of smoking shisha than those who were not. Support for tobacco control policies, especially bans on smoking in public places and sales to minors, was strongly associated with reduced shisha smoking. Although males showed a slightly higher prevalence, sex was not a significant factor after accounting for other variables. These findings provide important insight into the demographic, behavioral, and policy factors influencing shisha use among youth in this region. This study found an overall shisha smoking prevalence of 7.2% among adolescents in Ghana and Sierra Leone, a figure that conforms with emerging global trends showing increasing use of alternative tobacco products among young people (23). Globally, shisha smoking has gained popularity in urban areas (13,24) and among the youth, partly due to perceptions that it is less harmful than cigarettes (25). In Africa, though data remain limited, growing shisha use is being reported in countries like South Africa (26) and Nigeria (27,28). It is therefore not surprising that our findings confirm this trend in West Africa and call for urgent attention to this rising public health challenge. Shisha smoking was significantly higher in Sierra Leone compared to Ghana. This country difference may reflect varying tobacco control enforcement (19), cultural acceptance, or availability of shisha products (29). Across Africa, disparities in tobacco control policy implementation and enforcement remain a challenge (19,30,31). Despite these differences between the two countries, they could still benefit from strengthening regulations and consistent enforcement. Current cigarette smokers were almost ten times more likely to smoke shisha in Ghana and Sierra Leone. This finding is consistent with global evidence showing poly-tobacco use is common among the youth (32,33). Poly-tobacco use complicates cessation efforts by intensifying nicotine dependence (34) and sustaining dependence despite attempts to quit smoking (35). However, it also offers an opportunity to target both behaviors simultaneously during interventions (35,36). Tobacco control programs in Ghana and Sierra Leone should therefore integrate strategies addressing multiple tobacco products, including cigarettes and shisha. Students aged 13–17 had significantly lower odds of shisha smoking compared to the youngest group (age 11). This finding is unexpected, as it contrasts with most of the existing literature, which consistently reports a higher mean age (above 13 years) of shisha initiation (37,38). The observed pattern suggests early smoking initiation, which is concerning because early tobacco use increases the risk of long-term addiction (39–41). Globally and in Africa, prevention efforts often focus on older teens, but these findings highlight the need for earlier, age-appropriate education and prevention programs starting before adolescence (42,43). In our study, students who saw a smoking advertisement reported a lower prevalence of shisha smoking than their counterparts. This finding was unexpected, as it does not conform to most of the existing literature, which reports higher smoking rates among adolescents exposed to tobacco advertising and lower smoking rates for adolescents exposed to anti-smoking messages (44). The observed pattern could be attributed to random variation, but it also highlights the need for further investigation into the underlying factors driving this pattern. Being taught in school about the effects of tobacco use emerged as protective factor against shisha smoking though marginally, with students who were taught about smoking reporting lower smoking prevalence. This is consistent with other studies done in Africa (45) Support for tobacco control policies, especially bans on smoking in public and sales of tobacco products to minors, was strongly associated with lower shisha use. This supports the evidence that policy measures are effective deterrents (45–47). Increasing public education about tobacco laws and enhancing enforcement in the two countries will be essential. There is a need for countries in Africa to accelerate the adoption and implementation of comprehensive tobacco control frameworks, including the WHO Framework Convention on Tobacco Control (FCTC) (48). Sex showed a small, non-significant effect on shisha use after adjustment. While males often have higher tobacco use rates including that of shisha (24), cultural and social norms vary widely across settings which might explain why there was no association between gender and shisha smoking in our study. Policies should be gender-sensitive but focus broadly on all youth at risk (49). While tobacco control measures must address the diverse ways it affects boys and girls, they should not overlook the broader population of vulnerable adolescents. This study has several limitations that should be considered when interpreting the findings. The cross-sectional nature of the GYTS data limits establishing causal relationships; we cannot confirm that identified predictors caused shisha use. Additionally, self-reported data may have been affected by social desirability or recall bias, potentially leading to underestimation of the true prevalence of shisha smoking. Although the multivariable model accounted for potential confounders, residual confounding, a common limitation in observational studies might have remained and influenced the interpretation of findings. The study findings have limited generalizability to the broader African context as it only included data from two countries. Future research should use longitudinal designs and expand geographic coverage to overcome these limitations. Despite these limitations, the study has important strengths. By focusing on emerging tobacco products in African countries, this study addresses a significant gap in literature and provides valuable insight to inform policy and public health intervention. Furthermore, the application of robust statistical methods, including accounting for potential confounders, strengthens the validity and reliability of the results. In conclusion, shisha smoking among school-going adolescents in Ghana and Sierra Leone is a significant public health concern. Our findings review an urgent and emerging public health crisis among adolescents. This issue stems from early tobacco initiation, poly-tobacco use and weak enforcement of tobacco control measures. Addressing the growing threat requires effective tobacco control policies, early prevention efforts, and targeted education. Policymakers and public health practitioners in Ghana, Sierra Leone, and across Africa should prioritize comprehensive tobacco control strategies that specifically include alternative tobacco products like shisha. By ensuring strong enforcement and youth engagement, countries can protect the health of future generations.

In contrast to cigarette smoking, which has been declining in many countries due to strong tobacco control measures, shisha is often and mistakenly seen as a safer alternative (\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e, \u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e). This misconception has contributed to widespread use ranging from caf\u0026eacute;s in Europe and the Middle East to social gatherings in Asia and the Americas (\u003cspan additionalcitationids=\"CR6\" citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e). As a result, global health experts are increasingly worried about the long-term impact of shisha smoking on public health (\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eIn Africa, shisha use has been rising steadily (\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e, \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e). Many young people are drawn to it because of the flavored tobacco and the social atmosphere around shisha smoking (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e, \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e). Unfortunately, awareness of its health risks is still low. Studies have shown that shisha exposes users to harmful levels of nicotine, carbon monoxide, and cancer-causing substances (\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e). Despite the growing concerns, shisha lounges remain prevalent in many African cities, where tobacco control policies are either weak or inadequately enforced (\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eCountries such as Ghana and Sierra Leone are experiencing similar trends (\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e). Young people in these countries are increasingly experimenting with shisha at early ages, often under peer influence and exposed to environments where tobacco advertising is not strictly regulated (\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e, \u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e). Education efforts through schools and community programs are frequently under resourced to educate youths about these dangers (\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e). Although, policies restricting tobacco sales to minors and banning smoking in public places exist, their enforcement is inconsistent, allowing the habit to spread (\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eWhile studies have been conducted on shisha smoking among adolescents in Africa, we are not aware of a study that analyzed pooled data from two countries. The aim of this study is to examine the prevalence and predictors of shisha smoking among school-going adolescents in Ghana and Sierra Leone. The findings from this study will provide evidence that can guide targeted interventions, strengthen existing policies, and help reduce the rising burden of tobacco-related harm in these countries and across Africa.\u003c/p\u003e"},{"header":"METHODS","content":"\u003ch3\u003eData Source\u003c/h3\u003e\n\u003cp\u003eThis study used secondary data from the Global Tobacco Youth Surveys (GTYS) collected in 2017. The analysis focused on data from two West African countries: Ghana and Sierra Leone. The GYTS is a school based survey of students, in grades 7 to 9, aged 11 to 18 years. It is designed to produce a cross sectional national representative sample. The GYTS methodology for the sampling framework, selection of schools and classes, and data processing is standardized. The survey uses a standard questionnaire with core questions on tobacco use and key tobacco control variables and allows adaption to the needs of a particular country. All participants provided informed consent with their anonymity preserved through the use of unique identifiers instead of personal information. In addition, each country obtains ethical approval from the relevant authorities, ensuring compliance with local and international ethical standards. A more detailed description of the overall objectives and methodology of the GYTS are available elsewhere (20). The sample size and the schools are determined using a standard procedure and software developed by the Center for Disease Control and Prevention (CDC) upon receiving the sampling frame from the GYTS research coordinators. The actual sample size and its computation was not available, however, a minimum sample size of 1500 students, 50% of whom are female is required for the GYTS (20).

The Chi-square test of association was utilized to determine associations between various factors and current shisha smoking status. Additionally, univariate and multivariate logistic regression models were used to examine the associations between factors that may influence shisha smoking among school-going adolescents in Ghana and Sierra Leone (22). Variables that were found to be significantly associated (p\u0026lt;0.05) with current shisha smoking status in the univariate analyses were included in the multivariate models. Stepwise model selection with Akaike Information Criterion (AIC) was applied to identify the most parsimonious model while retaining age and sex in the model due to their known confounding effects. Adjusted odds ratios (aORs) with 95% confidence intervals and p-values were reported and used as measures of magnitude of associations. Age, gender, ever tried smoking cigarettes, taught in class about the dangers of smoking were controlled for in the full model. To visualize the relationship between age and the probability of current shisha smoking, predicted probabilities were computed from the final adjusted model. Using Bayesian simulations from the model\u0026rsquo;s posterior distribution (1,000 simulations), we estimated mean predicted probabilities and 95% credible intervals by age and sex. These predictions were plotted to illustrate risk patterns across adolescent age groups. All analyses were conducted using R (version 4.5.0).\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eEthical Considerations\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eEthical approval was obtained from the University of Zambia Biomedical Research Ethics Committee (Ref.

The overall sample for the two countries was nearly evenly split by sex, with 53% female and 47% male. Age distribution showed most participants were between 13 and 15 years old, representing over 70% of the sample. School grade levels ranged from 7 to 12, with the largest groups in grades 9 and 10.

Age-specific prevalence showed notable high rate of shisha use among youngest group (age 11), at 20.7%. Prevalence was lower ranging from 5.0% to 7.0% among those aged 13-14, and 7.5% among those aged 15 to 17. Males reported significantly higher prevalence (7.84%, 95% CI: 7.15-8.54) compared to females (6.60%, 95% CI: 6.00-7.21).\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eShisha smoking prevalence varied by school grade and attitudes toward tobacco control policies. Overall grade 7 students had a high prevalence (17.33%, 95% CI: 14.10-20.57), while older grades showed lower but steady rates (5.0% - 8.0%). Youth who did not support banning tobacco sales to minors had higher prevalence of shisha use (7.96%, 95% CI: 7.34-8.57) than those who supported such bans (6.01%, 95% CI: 5.34-6.67). Similarly, those opposing bans on smoking in public had extremely high prevalence (46.75%, 95% CI: 35.61-57.9) compared to (6.93%, 6.48-7.38) among supporters.

For example, crude ORs for age groups 13 to 17 were even lower (0.21\u0026ndash;0.32) than adjusted, suggesting confounding factors raised odds somewhat after adjustment. Crude OR for current smokers was 10.94 (95% CI: 8.79\u0026ndash;13.58; p \u0026lt; 0.001), close to the adjusted estimate. Country effect was smaller but still significant in crude (OR = 1.18; 95% CI: 1.03\u0026ndash;1.36; p = 0.017). Support for tobacco bans showed weaker protective effects in crude models (OR 0.74 for sales ban; OR 0.08 for public ban) but remained highly significant. Overall, the analysis highlights age, smoking status, country, and tobacco policy attitudes as key independent factors shaping shisha use among youth in these countries.\u003c/p\u003e\n\u003cp\u003eThe predicted probability of current shisha smoking among students varied across ages 11 to 17 as shown in Figure 1. The probability increased gradually from age 11 years until it peaked at 15 before slightly declining at ages 16 and 17 but it was still higher than in the younger age category. This suggests that mid-adolescence represents a crucial time for shisha initiation, with the risk increasing gradually from early to mid-adolescence and continuing into late adolescent years. These findings review the importance of targeting tobacco control activities in early adolescence to prevent an increase in shisha use as adolescents grow.\u003c/p\u003e"},{"header":"DISCUSSION","content":"\u003cp\u003eThis study estimates the prevalence and predictors of shisha smoking among school going adolescents in Ghana and Sierra Leone in 2017. Spatially, the study\u0026rsquo;s data were derived from two distinct countries with different cultural and regulatory environments, offering important regional insights. Sierra Leone accounted for a slightly larger portion of the sample than Ghana, which may influence the patterns observed. These geographic differences, combined with demographic and behavioral data, highlight areas where tobacco control efforts could be strengthened, especially regarding youth perceptions and policy awareness across West Africa.\u0026nbsp;The overall prevalence of current shisha smoking among adolescents in Ghana and Sierra Leone was 7.2%. Shisha smoking was significantly higher in Sierra Leone compared to Ghana, highlighting important regional differences. Current cigarette smokers were nearly ten times more likely to use shisha. Interestingly, adolescents aged 13 to 17 had significantly lower odds of smoking shisha compared to the younger group aged 11, suggesting early initiation may be a critical factor. Students who saw smoking advertisements were more likely to smoke as compared to those who did not. Surprisingly, adolescents who were taught in class about the effects of tobacco smoking reported a higher prevalence of smoking shisha than those who were not. Support for tobacco control policies, especially bans on smoking in public places and sales to minors, was strongly associated with reduced shisha smoking. Although males showed a slightly higher prevalence, sex was not a significant factor after accounting for other variables. These findings provide important insight into the demographic, behavioral, and policy factors influencing shisha use among youth in this region.\u003c/p\u003e\n\u003cp\u003eThis study found an overall shisha smoking prevalence of 7.2% among adolescents in Ghana and Sierra Leone, a figure that conforms with emerging global trends showing increasing use of alternative tobacco products among young people (23). Globally, shisha smoking has gained popularity in urban areas (13,24) and among the youth, partly due to perceptions that it is less harmful than cigarettes (25). In Africa, though data remain limited, growing shisha use is being reported in countries like South Africa (26) and Nigeria (27,28). It is therefore not surprising that our findings confirm this trend in West Africa and call for urgent attention to this rising public health challenge.\u003c/p\u003e\n\u003cp\u003eShisha smoking was significantly higher in Sierra Leone compared to Ghana. This country difference may reflect varying tobacco control enforcement (19), cultural acceptance, or availability of shisha products (29). Across Africa, disparities in tobacco control policy implementation and enforcement remain a challenge (19,30,31). Despite these differences between the two countries, they could still benefit from strengthening regulations and consistent enforcement.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eCurrent cigarette smokers were almost ten times more likely to smoke shisha in Ghana and Sierra Leone. This finding is consistent with global evidence showing poly-tobacco use is common among the youth (32,33). Poly-tobacco use complicates cessation efforts by intensifying nicotine dependence (34) and sustaining dependence despite attempts to quit smoking (35). However, it also offers an opportunity to target both behaviors simultaneously during interventions (35,36). Tobacco control programs in Ghana and Sierra Leone should therefore integrate strategies addressing multiple tobacco products, including cigarettes and shisha.\u003c/p\u003e\n\u003cp\u003eStudents aged 13\u0026ndash;17 had significantly lower odds of shisha smoking compared to the youngest group (age 11). This finding is unexpected, as it contrasts with most of the existing literature, which consistently reports a higher mean age (above 13 years) of shisha initiation (37,38). The observed pattern suggests early smoking initiation, which is concerning because early tobacco use increases the risk of long-term addiction (39\u0026ndash;41). Globally and in Africa, prevention efforts often focus on older teens, but these findings highlight the need for earlier, age-appropriate education and prevention programs starting before adolescence (42,43).\u003c/p\u003e\n\u003cp\u003eIn our study, students who saw a smoking advertisement reported a lower prevalence of shisha smoking than their counterparts. This finding was unexpected, as it does not conform to most of the existing literature, which reports higher smoking rates among adolescents exposed to tobacco advertising and lower smoking rates for adolescents exposed to anti-smoking messages (44). The observed pattern could be attributed to random variation, but it also highlights the need for further investigation into the underlying factors driving this pattern.\u003c/p\u003e\n\u003cp\u003eBeing taught in school about the effects of tobacco use emerged as protective factor against shisha smoking though marginally, with students who were taught about smoking reporting lower smoking prevalence. This is consistent with other studies done in Africa (45)\u003c/p\u003e\n\u003cp\u003eSupport for tobacco control policies, especially bans on smoking in public and sales of tobacco products to minors, was strongly associated with lower shisha use. This supports the evidence that policy measures are effective deterrents (45\u0026ndash;47). Increasing public education about tobacco laws and enhancing enforcement in the two countries will be essential. There is a need for countries in Africa to accelerate the adoption and implementation of comprehensive tobacco control frameworks, including the WHO Framework Convention on Tobacco Control (FCTC) (48).\u003c/p\u003e\n\u003cp\u003eSex showed a small, non-significant effect on shisha use after adjustment. While males often have higher tobacco use rates including that of shisha (24), cultural and social norms vary widely across settings which might explain why there was no association between gender and shisha smoking in our study. Policies should be gender-sensitive but focus broadly on all youth at risk (49). While tobacco control measures must address the diverse ways it affects boys and girls, they should not overlook the broader population of vulnerable adolescents.\u003c/p\u003e\n\u003cp\u003eThis study has several limitations that should be considered when interpreting the findings. The cross-sectional nature of the GYTS data limits establishing causal relationships; we cannot confirm that identified predictors caused shisha use. Additionally, self-reported data may have been affected by social desirability or recall bias, potentially leading to underestimation of the true prevalence of shisha smoking. Although the multivariable model accounted for potential confounders, residual confounding, a common limitation in observational studies might have remained and influenced the interpretation of findings. The study findings have limited generalizability to the broader African context as it only included data from two countries. Future research should use longitudinal designs and expand geographic coverage to overcome these limitations.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eDespite these limitations, the study has important strengths. By focusing on emerging tobacco products in African countries, this study addresses a significant gap in literature and provides valuable insight to inform policy and public health intervention. Furthermore, the application of robust statistical methods, including accounting for potential confounders, strengthens the validity and reliability of the results.\u003c/p\u003e\n\u003cp\u003eIn conclusion, shisha smoking among school-going adolescents in Ghana and Sierra Leone is a significant public health concern. Our findings review an urgent and emerging public health crisis among adolescents. This issue stems from early tobacco initiation, poly-tobacco use and weak enforcement of tobacco control measures. Addressing the growing threat requires effective tobacco control policies, early prevention efforts, and targeted education. Policymakers and public health practitioners in Ghana, Sierra Leone, and across Africa should prioritize comprehensive tobacco control strategies that specifically include alternative tobacco products like shisha. By ensuring strong enforcement and youth engagement, countries can protect the health of future generations.\u003c/p\u003e"},{"header":"Abbreviations","content":"\u003cp\u003e\u003cstrong\u003eAIC\u003c/strong\u003e \u0026ndash; Akaike Information Criterion\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAOR\u003c/strong\u003e \u0026ndash; Adjusted Odds Ratio\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eCDC\u003c/strong\u003e \u0026ndash; Center for Disease Control and Prevention\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eCI\u003c/strong\u003e \u0026ndash; Confidence Interval\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eFCTC\u003c/strong\u003e \u0026ndash; Framework Convention on Tobacco Control\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eGYTS\u003c/strong\u003e \u0026ndash; Global Youth Tobacco Survey\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eTAPS\u003c/strong\u003e \u0026ndash; Tobacco Advertising Promotion and Sponsorship\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eUS\u003c/strong\u003e \u0026ndash; United States\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eWHO\u003c/strong\u003e \u0026ndash; World Health Organization\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eAuthor\u0026rsquo;s contributions\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eJS performed data management, analysis and drafting the paper; WN and CZ reviewed the data management, analysis and the draft paper.

Yet in countries like Ghana and Sierra Leone, there remains a critical gap in understanding the behavioral patterns and underlying factors driving this trend.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods\u003cbr\u003e\n \u003c/strong\u003eWe retrieved secondary data from a public sphere collected using a cross-sectional study design. Overall, 12,281 students in grades associated with 11-18 year olds were selected using stratified two-stage cluster sampling. Descriptive statistics estimated smoking prevalence by age, sex, school grade, country, and survey year. Multivariate logistic regression models were used to determine associations between socio-demographic, behavioural, tobacco policy factors and current Shisha smoking. Adjusted odds ratios and their 95% confidence intervals are reported.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults\u003c/strong\u003e\u003cbr\u003e\n The overall prevalence of current shisha smoking was 7.2% (7.8% males and 6.6% of females). The prevalence was slightly higher in Sierra Leone (7.69%, 95% CI: 7.05-8.33) than Ghana (6.58%, 95% CI: 5.94-7.23). Adolescents who did not support banning tobacco sales to minors had higher shisha use (7.96%, 95% CI: 7.34-8.57) than their counterparts (6.01%, 95% CI: 5.34-6.67). Participants who smoked cigarettes, were more likely to smoke shisha compared to those who did not smoke (AOR = 9.86; 95% CI: 7.84–12.38; p \u0026lt; 0.001).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion\u003c/strong\u003e\u003cbr\u003e\nShisha smoking among school-going adolescents in Ghana and Sierra Leone reviewed emerging patterns suggesting early initiation and strong association with cigarette use. There is a need for stronger enforcement of tobacco control policies, targeting poly-tobacco use control and factors influencing early initiation. These findings provide valuable insight to inform tobacco control.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eClinical trial number:\u003c/strong\u003e not applicable\u003c/p\u003e","manuscriptTitle":"Prevalence and Predictors of Shisha Smoking in Ghana and Sierra Leone: Findings from the 2017 Global Youth Tobacco Surveys","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-03-08 14:19:30","doi":"10.21203/rs.3.rs-8960733/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2026-03-11T05:32:07+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2026-03-05T06:33:38+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2026-03-05T06:29:58+00:00","index":"","fulltext":""},{"type":"submitted","content":"Discover Public Health","date":"2026-02-24T19:47:29+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
