Abstract

Abstract Background Cardiometabolic diseases have their origins early in life, yet data on the co-occurrence and clustering of cardiometabolic risk factors among children and adolescents in sub-Saharan Africa remain limited. Understanding age-related patterns of cardiometabolic risk clustering is essential for informing early prevention strategies. Methods We conducted a cross-sectional study among children and adolescents aged 6–19 years who participated in community health outreach programmes in semi-urban communities of North-Central Nigeria between 2019 and 2023. Anthropometric measurements, blood pressure, and random blood glucose were assessed using standardized protocols. Age- and sex-and height- appropriate definitions were applied for cardiometabolic risk factors. Cardiometabolic risk clustering was defined as the presence of two or more predefined risk factors. Prevalence estimates were described overall and by age group, and logistic regression was used to examine demographic factors associated with risk clustering. Results A total of 263 participants were included (95 aged 6 − 12 years and 168 aged 13 − 19 years). Overweight or obesity was present in 18.3% of participants, central obesity in 11.8%, elevated blood pressure in 58.2%, and dysglycaemia in 19.8%. Two or more cardiometabolic risk factors were observed in 26.6% of participants, occurring in 22.1% of children aged 6 − 12 years and 29.2% of adolescents aged 13 − 19 years. In regression analyses, adolescents had higher odds of cardiometabolic risk clustering than younger children, although this association was not statistically significant. Sex was not associated with risk clustering. Conclusions Cardiometabolic risk factors are common and frequently clustered among children and adolescents in North-Central Nigeria, with clustering evident from early childhood. These findings highlight the need for early, integrated, and population-based strategies for cardiometabolic disease prevention in paediatric populations.

Cardiometabolic risk Risk-factor clustering Children Adolescents Hypertension Obesity Dysglycaemia Blood pressure Nigeria Sub-Saharan Africa 1. Introduction Cardiometabolic diseases, including type 2 diabetes mellitus (T2DM) and cardiovascular diseases (CVDs), are major causes of morbidity and mortality worldwide. Increasing evidence indicates that the foundations of these conditions are established during childhood and adolescence, with early-life exposure to overweight, obesity, elevated blood pressure, and dysglycaemia predisposing to cardiometabolic disease in adulthood. 1 In recent decades, the prevalence of these risk factors among children and adolescents has risen substantially, driven by urbanisation, dietary transitions, reduced physical activity, and socioeconomic change. 2 – 4 Once largely confined to high-income countries, this growing cardiometabolic burden is now increasingly concentrated in low- and middle-income countries (LMICs), where the pace of nutritional and lifestyle transition has been most rapid. 2 , 4 , 5 Cardiometabolic risk factors in early life rarely occur in isolation and frequently cluster within individuals, reflecting shared biological, behavioural, and environmental influences. 6 , 7 The presence of multiple cardiometabolic abnormalities in childhood has been associated with early vascular dysfunction, insulin resistance, and subclinical atherosclerosis. 8 – 10 These alterations may persist into adulthood and increase the risk of future cardiovascular and metabolic disease. Despite increasing global attention to childhood cardiometabolic health, evidence from sub-Saharan Africa remains limited. In Nigeria, most available studies have examined individual risk factors such as obesity, hypertension, or impaired glucose regulation, often in narrow age groups or localised settings. 11 , 12 Data describing the co-occurrence and clustering of cardiometabolic risk factors among children and adolescents are scarce, particularly in North-Central Nigeria, a region undergoing rapid demographic, nutritional, and lifestyle transitions. This study therefore aimed to describe the prevalence and clustering of cardiometabolic risk factors among children and adolescents aged 6–19 years in North-Central Nigeria. 2. Methods 2.1 Study Design and Setting A cross-sectional study was conducted between 2021 and 2023 during community health outreach programmes in semi-urban communities of Okene and Lokoja (Kogi State); as well as Gwagwalada (FCT, Abuja) in North-Central Nigeria. Recruitment occurred intermittently during outreach activities. 2.2 Study Population Children and adolescents aged 6–19 years attending outreach screenings were eligible. Apparently healthy participants were included, while acutely ill children and those without parental consent were excluded. Written informed consent and age-appropriate assent were obtained. 2.3 Sampling Method and Sample Size Convenience sampling was used, and all eligible attendees during the study period were enrolled. No formal sample size calculation was performed. 2.4 Data Collection and Measurements Trained personnel administered structured questionnaires and performed standardized clinical and anthropometric assessments at outreach venues. Blood pressure was measured after five minutes’ rest using a calibrated digital sphygmomanometer, with two readings averaged. 13 Weight, height, and waist circumference were measured using standard techniques, and body mass index (BMI) was calculated. 14 Random blood glucose was assessed by finger-prick using an Accu-Chek® glucometer, with standard quality-control procedures observed. 15 2.5 Definition of Cardiometabolic Risk Factors Risk factors were defined using age- and sex-specific criteria. Overweight and obesity were defined using World Health Organization (WHO) BMI-for-age z-scores for ages 5–19 years, with BMI-for-age > + 1 standard deviation indicating overweight and > + 2 standard deviations indicating obesity. 16 , 17 Central obesity was defined as waist circumference ≥ 90th percentile for age and sex. 18 Raised blood pressure was defined as any blood pressure above the normal range for age according to the 2017 American Academy of Pediatrics guideline: 13 systolic and/or diastolic blood pressure ≥ 90th percentile in children aged < 13 years, or ≥ 120/80 mmHg in adolescents aged ≥ 13 years. Dysglycaemia was defined as random blood glucose ≥ 11.1 mmol/L and used as a screening indicator. 19 A composite cardiometabolic risk score was created by summing all risk factors with equal weighting; this unvalidated score was used for exploratory analyses. Cardiometabolic risk-factor clustering was defined as the presence of ≥ 2 risk factors. 9 2.6 Statistical Analysis Data were analysed using Stata version 14 (StataCorp, College Station, TX, USA). Continuous variables were summarised as medians (IQR) and categorical variables as frequencies and percentages. Baseline characteristics and prevalence of cardiometabolic risk factors were described overall and by age group. Logistic regression was used to examine factors associated with cardiometabolic risk clustering (≥ 2 risk factors), with age group and sex included a priori. Results are presented as odds ratios (ORs) with 95% confidence intervals (CIs), and statistical significance was set at p < 0.05. 3. Results 3.1 Study Population The combined median age was 15.0 years (IQR 11.0–18.0), with medians of 9.0 years (IQR 7.0–11.0) in children and 17.0 years (IQR 15.0–18.0) in adolescents. Females constituted 61.6% of participants, representing 49.5% of children and 68.5% of adolescents. The overall median BMI was 20.1 kg/m² (IQR 16.9–24.0), with medians of 16.7 kg/m² (IQR 14.2–20.7) in children and 21.7 kg/m² (IQR 19.0–24.3) in adolescents. The overall median waist circumference was 67.0 cm (IQR 58.0–75.0), with medians of 55.0 cm (IQR 52.0–64.0) in children and 70.0 cm (IQR 64.0–77.0) in adolescents. Median systolic blood pressure was 110.0 mmHg (IQR, 100.0–130.0) overall and was identical in both age groups. Median diastolic blood pressure was 70.0 mmHg (IQR, 70.0–80.0) overall, with higher values in children (80.0 mmHg; IQR, 70.0–90.0) than in adolescents (70.0 mmHg; IQR, 70.0–80.0). Median random blood glucose was 5.9 mmol/L (IQR, 5.1–7.0) overall, with similar values in children and adolescents. 3.2 Prevalence of Individual Cardiometabolic Risk Factors Overall, raised blood pressure was the most prevalent risk factor (58.2%; 95% CI, 52.0–64.2), followed by dysglycaemia (19.8%; 95% CI, 15.1–25.1), overweight/obesity (18.3%; 95% CI, 13.7–23.5), and central obesity (11.8%; 95% CI, 8.2–16.3) (Table 2 ). Among children, prevalences were 64.2% for raised blood pressure, 16.8% for overweight/obesity, 13.7% for dysglycaemia, and 7.4% for central obesity. Among adolescents, corresponding prevalences were 54.8%, 19.0%, 23.2%, and 14.3%, respectively. 3.3 Distribution of Cardiometabolic Risk-Factor Counts Overall, 26.2% of participants had no cardiometabolic risk factors, 47.2% had one, and 26.6% had two or more (Table 3 ). Among children aged 6–12 years, 25.3% had no risk factors, 52.6% had one, and 22.1% had clustered risk factors. Corresponding proportions among adolescents were 26.7%, 44.1%, and 29.2%, respectively. Risk clustering (≥ 2 factors) was more frequent in adolescents than in children (29.2% vs. 22.1%) and in females than males (28.4% vs. 23.8%). Three or more risk factors were uncommon, occurring in fewer than 7% of participants in any subgroup. 3.4 Factors Associated with Cardiometabolic Risk-Factor Clustering In logistic regression analysis (Table 4 ), adolescents aged 13–19 years had higher odds of cardiometabolic risk clustering than children aged 6–12 years, but this association was not statistically significant (OR 1.39; 95% CI 0.78–2.48; p = 0.261). Sex was also not associated with clustering (OR for males vs females 0.83; 95% CI 0.47–1.49; p = 0.535). 4. Discussion Cardiometabolic risk factors were common and frequently clustered among children and adolescents in North-Central Nigeria. More than one-quarter had two or more concurrent risk factors, with clustering more frequent among adolescents but already evident in children aged 6–12 years. The lack of independent associations with age group or sex suggests that cardiometabolic vulnerability is established early and broadly distributed in this population. Raised blood pressure was the most prevalent abnormality in this study, affecting more than half of participants, a burden substantially higher than that reported in most Nigerian paediatric studies. School-based surveys have reported prevalences of 9.1% to 22.7% in comparable age groups. 11 , 20 In Kogi State, the same region as this study, Ejike et al. reported higher mean systolic blood pressure in urban than non-urban adolescents, although prevalence estimates were not provided. 21 While global analyses show rising childhood blood pressure, 2,22 the magnitude observed here suggests a particularly high-risk profile. Because childhood blood pressure tracks into adulthood and predicts later cardiovascular disease, 8,10 this finding indicates a substantial future cardiovascular burden. Overweight and obesity occurred at levels comparable to those reported in high-income countries and within the range described in urbanising African and Nigerian populations. 5 , 12 , 23 This convergence indicates that semi-urban North-Central Nigeria is already experiencing adiposity patterns similar to higher-income and rapidly urbanising settings, reflecting shared dietary transition, physical inactivity, and expanding urbanisation. Central obesity, although less prevalent than general overweight, was more frequent among adolescents. This pattern is consistent with evidence that pubertal visceral fat accumulation predicts later insulin resistance and subclinical atherosclerosis independent of body mass index. 9 , 10 The higher prevalence among adolescents in this cohort therefore suggests early emergence of a risk phenotype likely to persist into adulthood. 24 Dysglycaemia, particularly among adolescents, further supports this trajectory. Studies from Nigeria and South Africa link early glucose disturbances to adiposity and sedentary behaviour, 25,26 with pubertal insulin resistance providing a plausible mechanism for the higher prevalence observed in this age group. A central contribution of this study is the high prevalence of cardiometabolic risk clustering. The proportion with two or more concurrent risk factors is comparable to paediatric cohorts in Europe, North America, and Asia, where clustering predicts adult metabolic syndrome, atherosclerosis, and T2DM. 9 , 10 , 27 The presence of clustering in both children and adolescents supports a life-course model in which cardiometabolic risk begins early and tracks over time, reflecting shared pathways such as insulin resistance and low-grade inflammation, amplified by urbanisation-related exposures. 28 , 29 Importantly, clustering was already present in more than one-fifth of children aged 6–12 years, indicating that adverse risk trajectories may begin before adolescence. 10 , 28 The absence of a clear sex difference suggests that adiposity and pubertal stage may be more important determinants of early risk aggregation than sex alone. 18 These findings support integrated screening of multiple cardiometabolic risk factors in paediatric populations, as single–risk-factor approaches may miss children at highest cumulative risk. Community outreach and school-based programmes provide practical platforms for early identification and prevention. Incorporating paediatric cardiometabolic assessment into broader noncommunicable disease strategies, using a life-course approach, is essential to reduce future cardiovascular burden. 5. Strengths and Limitations Strengths of this study include the community-based design, inclusion of both children and adolescents, and the use of age- and sex-specific definitions of cardiometabolic risk factors. Limitations include the cross-sectional design, outreach-based measurements, use of random blood glucose instead of fasting measures, absence of lipid profiling (HDL and triglycerides), lack of local waist circumference reference values, and convenience sampling, which may limit causal inference and generalisability. 6. Conclusion Cardiometabolic risk factors are common and frequently clustered among children and adolescents in North-Central Nigeria. Early clustering highlights the need for integrated, life-course prevention strategies centred on early detection, school-based interventions, and supportive policy environments.

Understanding age-related patterns of cardiometabolic risk clustering is essential for informing early prevention strategies.\u003c/p\u003e\u003cp\u003e\u003cb\u003eMethods\u003c/b\u003e\u003c/p\u003e \u003cp\u003e We conducted a cross-sectional study among children and adolescents aged 6\u0026ndash;19 years who participated in community health outreach programmes in semi-urban communities of North-Central Nigeria between 2019 and 2023. Anthropometric measurements, blood pressure, and random blood glucose were assessed using standardized protocols. Age- and sex-and height- appropriate definitions were applied for cardiometabolic risk factors. Cardiometabolic risk clustering was defined as the presence of two or more predefined risk factors. Prevalence estimates were described overall and by age group, and logistic regression was used to examine demographic factors associated with risk clustering.\u003c/p\u003e\u003cp\u003e\u003cb\u003eResults\u003c/b\u003e\u003c/p\u003e \u003cp\u003eA total of 263 participants were included (95 aged 6 \u0026minus;\u0026thinsp;12 years and 168 aged 13 \u0026minus;\u0026thinsp;19 years). Overweight or obesity was present in 18.3% of participants, central obesity in 11.8%, elevated blood pressure in 58.2%, and dysglycaemia in 19.8%. Two or more cardiometabolic risk factors were observed in 26.6% of participants, occurring in 22.1% of children aged 6 \u0026minus;\u0026thinsp;12 years and 29.2% of adolescents aged 13 \u0026minus;\u0026thinsp;19 years. In regression analyses, adolescents had higher odds of cardiometabolic risk clustering than younger children, although this association was not statistically significant. Sex was not associated with risk clustering.\u003c/p\u003e\u003cp\u003e\u003cb\u003eConclusions\u003c/b\u003e\u003c/p\u003e \u003cp\u003eCardiometabolic risk factors are common and frequently clustered among children and adolescents in North-Central Nigeria, with clustering evident from early childhood.
