The present study was conducted with the aim of investigating the relationship between WWI and cardiovascular disease (CVD). Methods: This cross-sectional study included 8,899 participants from the Ravansar non-communicable diseases study (RaNCD) cohort study. The WWI was calculated by dividing waist circumference (WC) by the square root of weight. CVD is described as having a history of stroke, ischemic heart disease (IHD), angina, heart failure, myocardial infarction (MI), or using medication for CVD. The study utilized multiple logistic regression to assess the association between WWI and CVD. Results: The average age of the participants was 47.52± 8.29 years, 45.30% were men and 41.13% were rural residents. The prevalence of CVD was 17.36%. A positive association between WWI and CVD was observed. Participants in the highest quartile of WWI had a 36% (OR= 1.36, 95%CI:1.11, 1.78) higher odds of CVD than those in the lowest quartile (OR= 1.03, 95%CI: 0.79, 1.33) (Ptrend= 0.010) . The subgroup analyses revealed stronger associations between WWI and CVD in participants older than 50 years of age, male, urban residents, high SES, and passive smokers (P<0.001). The receiver operating characteristic (ROC) analysis indicated that WWI has a greater ability to predict CVD (AUC: 0.64, 95%CI: 0.61, 0.64) compared to body mass index (BMI) (AUC: 0.60, 95%CI: 0.58, 0.61) and WC (AUC: 0.61, 95%CI: 0.59, 0.62) . Conclussion: The association between higher WWI and an increased risk of CVD suggests that WWI management is crucial for preventing CVD. Cardiovascular diseases obesity weight-adjusted-waist index Persian Figures Figure 1 Figure 2 Introduction Obesity represents a significant risk factor for numerous chronic metabolic conditions that have been considered in the health system [ 1 – 3 ]. It has been estimated that by 2030, around 38% of the world's adult population will be obese [ 4 ]. In a meta-analysis study by Wong et al. (2020), the overall prevalence of central obesity in the world was reported to be 41.5% [ 5 ]. Previous studies have indicated that obesity increases the risk of CVD [ 6 , 7 ]. However, onflicting findings from some studies suggest that overweight and obese individuals may have a lower risk of CVD and hypertension compared to those with normal weight, and being overweight or obese may play a protective role [ 8 – 10 ]. Among various anthropometric indices, body mass index (BMI) and waist circumference (WC) are widely used as the primary indices to assess both general and central obesity [ 11 ]. Nevertheless, these markers are not able to distinguish between fat and muscle mass [ 12 ]. Park and et al. (2018) introduced the weight-adjusted-waist index (WWI) as a new measure of obesity [ 13 ]. This index assesses central obesity by taking into account both muscle and fat mass, and it is calculated by dividing WC by the square root of body weight [ 14 , 15 ]. Several studies have reported a positive association between WWI and chronic diseases such as CVD, stroke, non-alcoholic fatty liver disease (NAFLD) and chronic kidney disease [ 16 – 19 ]. However, a comprehensive study in this field has not been conducted in Iran. CVD is a multifactorial chronic condition, with obesity identified as one of its risk factors. Consequently, reducing obesity can be effective in the prevention and management of CVD. A robust definition of obesity highlights the strength of the connection between this risk factor and CVD. Hence, the current study aims to explore the association between WWI and CVD among adults in western Iran. Methods Data sources and participants This study is a cross-sectional analysis of data from the baseline phase of the Ravansar non-communicable diseases study (RaNCD) cohort study [ 20 ]. The RaNCD cohort is one of the Prospective Epidemiological Research Studies in Iran (PERSIAN) [ 21 ], which started with a 15-year design since 2014 in Ravansar city located in Kermanshah province in the west of Iran. The study population of RaNCD cohort is urban and rural adult men and women of Ravansar. All participants from the initial phase of the RaNCD cohort were involved in this research. Following the application of exclusion criteria, 8,899 participants were examined ( Fig. 1 ). Study variables The data was collected in compliance with the cohort study protocol, and trained professionals used digital questionnaires to gather information. The socio-economic status (SES) was established by considering factors such as education level, place of residence, welfare amenities and wealth through the principal component analysis (PCA) method. After this analysis, the SES was divided into three categories (low, moderate, and high) [ 22 ]. Physical activity was evaluated by using 22 questions regarding sports, work, and leisure activities over a 24-hour period, measured in MET/hour per day [ 23 ]. Participants who stated that they had smoked more than 100 cigarettes in their lifetime were grouped as current smokers. Exposure to cigarette smoke at home, in the workplace, etc., is defined as passive smoking in people who are not smokers themselves [ 24 ]. The anthropometric measurements such as BMI, percent body fat (PBF), fat mass index (FMI), waist-hip ratio (WHR), WC, visceral fat area (VFA), skeletal muscle mass (SMM) and total body weight (TBW) were determined using an Impedance Analyzer BIA (Inbody 770, Inbody Co, Seoul, Korea). The dietary intake of participants was assessed using the food frequency questionnaire (FFQ) [ 25 ]. The lipid profile, consisting of triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and fasting blood sugar (FBS), was assessed by drawing 25 cc of blood from the participants. As per the protocol, participants were instructed to fast for 8–12 hours before the blood collection. The WWI was computed by dividing the waist circumference (cm) by the square root of the body weight (kg) [ 13 ]. A patient with cardiovascular disease (CVD) was someone who had experienced at least one of the following conditions: a history of ischemic heart disease (IHD), heart failure, angina, stroke, myocardial infarction (MI), and/or was currently taking medication for CVD. The participants' systolic and diastolic blood pressure (SBP and DBP) were assessed using the standard method while seated on a chair, following a 10-minute rest period, with measurements taken from both the right and left arms [ 26 ]. Subsequently, the average was computed. Participants with SBP ≥ 140mmHg and/or DBP ≥ 90mmHg, or those taking antihypertensive medications, were classified as hypertensive [ 26 ]. Statistical analysis In this study, Stata software version 14.2 (Stata Corp, College Station, TX, USA) was used to perform all analyses. The study was presented the basic characteristics of the participants as mean ± standard deviation and number (percentage) across WWI quartiles. We used the one-way ANOVA test for continuous variables and the chi-square test for qualitative variables to compare the differences among WWI quartiles. Logistic regression analysis was conducted to explore the association between CVD and WWI. The multiple regression model was adjusted for age, sex, residence, SES, smoking, physical activity, hypertension, energy intake, FBS, LDL, HDL, TG and TC variables. Throughout the analyses, a p-value of less than 0.05 with 95% confidence intervals (CIs) was deemed significant. Results The average age of the participants was 47.52 ± 8.29 years, 45.30% were men and 41.13% were rural residents. Among the 8,899 participants, 1445 (17.36%) had a CVD. Participants in the highest WWI quartile had significantly higher age compared to those in the lowest quartile (43.90 ± 7.16 vs. 51.10 ± 8.38, Ptrend < 0.001). The prevalence of hypertension and CVD has increased significantly across WWI quartiles (Ptrend < 0.001). The level of vigorous physical activity in the fourth WWI quartile is lower than that in the first quartile (Ptrend < 0.001). The average FBS, LDL-C, HDL-C and TC across WWI quartiles have increased significantly (Ptrend < 0.001) ( Table 1 ).

Moreover, with every unit increase in the WWI, the odds of CVD increased by 24% in men and 14% in women (P < 0.05). In urban and rural, the odds of CVD have increased with the rise in the WWI, although this increase was not statistically significant in the rural. The findings of the ROC analysis revealed that the WWI exhibited superior predictive capability (AUC: 0.64, 95% CI: 0.61, 0.64) compared to BMI (AUC: 0.60, 95% CI: 0.58, 0.61) and WC (AUC: 0.61, 95% CI: 0.59, 0.62) in predicting CVD within the studied population ( Fig. 2 ). Discussion In this cross-sectional study involving 8,899 Iranian adults was found a positive association between WWI and CVD. The odds of developing CVD in the second, third, and fourth quartiles of WWI were 1.03, 1.25, and 1.36 times higher than in the first quartile, respectively. Furthermore, subgroup analyses revealed a stronger association between WWI and CVD in participants older than 50 years, male, urban residents, high SES, and among passive smokers. The findings of the ROC analysis revealed that the WWI exhibited superior predictive capability compared to BMI and WC in predicting CVD within the studied population. A cross-sectional study of US adults indicates a positive association between WWI and CVD [ 16 ]. In a prospective study involving a Chinese population, Ding et al. discovered a non-linear positive relationship between CVD mortality and WWI [ 27 ]. A cross-sectional study on 23,389 participants of the National Health and Nutrition Examination Survey (NHANES) has also shown that the prevalence of stroke increases significantly with increasing WWI [ 17 ]. Our study was also consistent with previous studies and indicated a positive association between WWI and the odds of CVD. Given that weight is adjusted in the calculation of the WWI Index, this metric primarily reflects central obesity independently of weight. WWI has demonstrated superior accuracy compared to BMI [ 14 , 28 , 29 ]. Traditionally, changes in body weight were frequently utilized in the BMI formula to indicate fat accumulation and obesity in the adult population due to height stability. However, in recent years, researchers have raised doubts about this concept [ 8 , 30 ]. Furthermore, with the introduction of the muscle-fat axis concept, researchers have noted that weight loss can also be associated with a reduction in muscle mass, often accompanied by an increase in visceral fat. This may suggest a more precise assessment of obesity [ 31 ]. Several non-traditional obesity indices have been found to accurately predict metabolic diseases including CVD, such as Visceral adiposity index (VAI), body roundness index (BRI), and a body shape index (ABSI) and atherogenic index of plasma (AIP) [ 32 , 33 ]. Hamzeh et al.'s research involving 7,362 individuals demonstrated that VAI and AIP levels are reliable markers for predicting CVD [ 33 ]. Nonetheless, the calculation of these indicators can be complex and necessitate invasive methods. Recent studies have indicated that WWI is a better predictor of the risk of metabolic diseases compared to BMI and WC [ 18 , 34 , 35 ]. In the present study, ROC curve analysis revealed that WWI exhibits greater predictive power for CVD compared to BMI and WC. In general, computing WWI is straightforward, cost-effective, and feasible. The WWI's superior efficacy in forecasting CVD risk is evident and calls for the consideration of healthcare providers within health systems. The subgroup analyses identified a more robust link between WWI and CVD among individuals aged over 50, while two prior studies suggested that the association between WWI and CVD was stronger in younger individuals (under 50 years), they attributed this to the higher obesity rates in younger age groups [ 16 , 17 ]. This discrepancy could be explained by the nearly equal prevalence of obesity in both age groups in the current study. The association between WWI and CVD can be explained by various mechanisms. Central obesity can elevate oxidative stress in the body, closely linked to atherosclerosis development [ 36 , 37 ]. An increased WWI signifies an accumulation of excessive body fat and a reduction in muscle mass. This imbalance between muscle and fat leads to disturbances in adipocytokine release, inflammatory responses, endothelial dysfunction, and diminished physical function, culminating in the development of CVD [ 38 – 40 ]. Additionally, metabolic conditions associated with obesity like glucose intolerance, hypertriglyceridemia, and hypertension also heighten the risk of CVD, particularly stroke [ 41 ]. This study has several strong points. Firstly, we utilized a national sample of the general adult population in Western Iran from the RaNCD study, which implemented strict study protocols and quality controls. Secondly, to enhance result accuracy, we adjusted for most potential confounding variables. Nevertheless, it cannot be claimed that we eliminated the impact of all potential confounding variables. However, there were limitations in this study. The cross-sectional nature of the research prevented us from establishing a direct cause-and-effect relationship between WWI and CVD. Therefore, additional longitudinal studies are required to validate these results. Conclusion The results of the current study indicate that high levels of WWI are strongly associated to a higher risk of CVD in Iranian adults. A more robust association was observed between WWI and CVD in participants older than 50 years, male, urban residents, with high SES, and among passive smokers. Furthermore, the WWI was identified as the best obesity index for predicting CVD compared to BMI and WC in the study population. Therefore, WWI management is recommended for preventing CVD in Iranian adults. However, further confirmation of this finding is needed through longitudinal and prospective studies.

It has been estimated that by 2030, around 38% of the world's adult population will be obese [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. In a meta-analysis study by Wong et al. (2020), the overall prevalence of central obesity in the world was reported to be 41.5% [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. Previous studies have indicated that obesity increases the risk of CVD [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e, \u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e].

Nevertheless, these markers are not able to distinguish between fat and muscle mass [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Park and et al. (2018) introduced the weight-adjusted-waist index (WWI) as a new measure of obesity [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. This index assesses central obesity by taking into account both muscle and fat mass, and it is calculated by dividing WC by the square root of body weight [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e, \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e].

In a prospective study involving a Chinese population, Ding et al. discovered a non-linear positive relationship between CVD mortality and WWI [\u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e]. A cross-sectional study on 23,389 participants of the National Health and Nutrition Examination Survey (NHANES) has also shown that the prevalence of stroke increases significantly with increasing WWI [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. Our study was also consistent with previous studies and indicated a positive association between WWI and the odds of CVD.\u003c/p\u003e \u003cp\u003eGiven that weight is adjusted in the calculation of the WWI Index, this metric primarily reflects central obesity independently of weight. WWI has demonstrated superior accuracy compared to BMI [\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e, \u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e, \u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e]. Traditionally, changes in body weight were frequently utilized in the BMI formula to indicate fat accumulation and obesity in the adult population due to height stability. However, in recent years, researchers have raised doubts about this concept [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e]. Furthermore, with the introduction of the muscle-fat axis concept, researchers have noted that weight loss can also be associated with a reduction in muscle mass, often accompanied by an increase in visceral fat. This may suggest a more precise assessment of obesity [\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e]. Several non-traditional obesity indices have been found to accurately predict metabolic diseases including CVD, such as Visceral adiposity index (VAI), body roundness index (BRI), and a body shape index (ABSI) and atherogenic index of plasma (AIP) [\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e, \u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e]. Hamzeh et al.'s research involving 7,362 individuals demonstrated that VAI and AIP levels are reliable markers for predicting CVD [\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e]. Nonetheless, the calculation of these indicators can be complex and necessitate invasive methods. Recent studies have indicated that WWI is a better predictor of the risk of metabolic diseases compared to BMI and WC [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e, \u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e, \u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e]. In the present study, ROC curve analysis revealed that WWI exhibits greater predictive power for CVD compared to BMI and WC. In general, computing WWI is straightforward, cost-effective, and feasible. The WWI's superior efficacy in forecasting CVD risk is evident and calls for the consideration of healthcare providers within health systems.\u003c/p\u003e \u003cp\u003eThe subgroup analyses identified a more robust link between WWI and CVD among individuals aged over 50, while two prior studies suggested that the association between WWI and CVD was stronger in younger individuals (under 50 years), they attributed this to the higher obesity rates in younger age groups [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. This discrepancy could be explained by the nearly equal prevalence of obesity in both age groups in the current study.\u003c/p\u003e \u003cp\u003eThe association between WWI and CVD can be explained by various mechanisms. Central obesity can elevate oxidative stress in the body, closely linked to atherosclerosis development [\u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e, \u003cspan citationid=\"CR37\" class=\"CitationRef\"\u003e37\u003c/span\u003e]. An increased WWI signifies an accumulation of excessive body fat and a reduction in muscle mass. This imbalance between muscle and fat leads to disturbances in adipocytokine release, inflammatory responses, endothelial dysfunction, and diminished physical function, culminating in the development of CVD [\u003cspan additionalcitationids=\"CR39\" citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e]. Additionally, metabolic conditions associated with obesity like glucose intolerance, hypertriglyceridemia, and hypertension also heighten the risk of CVD, particularly stroke [\u003cspan citationid=\"CR41\" class=\"CitationRef\"\u003e41\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThis study has several strong points. Firstly, we utilized a national sample of the general adult population in Western Iran from the RaNCD study, which implemented strict study protocols and quality controls. Secondly, to enhance result accuracy, we adjusted for most potential confounding variables. Nevertheless, it cannot be claimed that we eliminated the impact of all potential confounding variables. However, there were limitations in this study. The cross-sectional nature of the research prevented us from establishing a direct cause-and-effect relationship between WWI and CVD. Therefore, additional longitudinal studies are required to validate these results.\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003eThe results of the current study indicate that high levels of WWI are strongly associated to a higher risk of CVD in Iranian adults.

The present study was conducted with the aim of investigating the relationship between WWI and cardiovascular disease (CVD).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods: \u003c/strong\u003eThis cross-sectional study included 8,899 participants from the Ravansar non-communicable diseases study (RaNCD) cohort study. The WWI was calculated by dividing waist circumference (WC) by the square root of weight. CVD is described as having a history of stroke, ischemic heart disease (IHD), angina, heart failure, myocardial infarction (MI), or using medication for CVD. The study utilized multiple logistic regression to assess the association between WWI and CVD.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults: \u003c/strong\u003eThe average age of the participants was 47.52± 8.29 years, 45.30% were men and 41.13% were rural residents. The prevalence of CVD was 17.36%. A positive association between WWI and CVD was observed. Participants in the highest quartile of WWI had a 36% (OR= 1.36, 95%CI:1.11, 1.78) higher odds of CVD than those in the lowest quartile (OR= 1.03, 95%CI: 0.79, 1.33) (Ptrend= 0.010)\u003cstrong\u003e. \u003c/strong\u003eThe subgroup analyses revealed stronger associations between WWI and CVD in participants older than 50 years of age, male, urban residents, high SES, and passive smokers (P\u0026lt;0.001).\u003cstrong\u003e \u003c/strong\u003eThe receiver operating characteristic (ROC) analysis indicated that WWI has a greater ability to predict CVD (AUC: 0.64, 95%CI: 0.61, 0.64) compared to body mass index (BMI) (AUC: 0.60, 95%CI: 0.58, 0.61) and WC (AUC: 0.61, 95%CI: 0.59, 0.62)\u003cstrong\u003e.\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclussion: \u003c/strong\u003eThe association between higher WWI and an increased risk of CVD suggests that WWI management is crucial for preventing CVD.\u003c/p\u003e","manuscriptTitle":"Association between weight-adjusted-waist index and cardiovascular diseases: a cross-sectional study based on RaNCD cohort data","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2024-05-07 16:11:50","doi":"10.21203/rs.3.rs-4331367/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"
