Metabolic syndrome (MetS) is a cluster of metabolic conditions that aggravate the likelihood of cardiovascular diseases and type 2 diabetes mellitus. This study was aimed to identify the best obesity index to determine MetS. This was a cross-sectional study and part of the Ellisras Longitudinal Study where 593 (289 males and 304 females) adults aged 22–30 years took part. Confirmatory factor analysis was used to test the single-factor models of MetS defined by mid arterial pressure, fasting blood glucose, triglycerides and commonly selected obesity indices such as Neck circumference (NC), Body mass index (BMI), Waist circumference (WC) and Waist to height ratio (WHtR) as indicators of MetS. It was found that a single model fit built based on WC and WHtR suggested a better fit index than NC and BMI in males, whereas, a model built on NC obtained a better fit index for females than other factor models. In conclusion, the result of the present study suggests that in rural Ellisras adult’s, WC and WHtR are the best obesity indices for determining MetS in males and NC in females than other indices. Hence, longitudinal studies are recommended to allow causality to be drawn between obesity indices and MetS.

Background: Metabolic syndrome (MetS) is the key risk factor for cardiovascular disease (CVD) development. However, lifestyle habits including high consumption of sugar-sweetened beverages (SSBs) contribute to its onset. The current study was aimed at investigating the association between SSBs consumption and MetS components among young adults aged 22 to 30 years. Methods: This was a cross-sectional study where a total of 596 young adults (307 females and 287 males) participated. Blood pressure, biochemical assessment, and anthropometric measurements were taken following protocols. A validated 24 h recall questionnaire and food manuals were used to collect SSBs data. Binary logistic regression was applied to determine the association between SSBs consumption and MetS components. Results: In males, high SSBs consumption increased the risk of high fasting blood glucose (FBG) (p < 0.05). In females, high and low SSBs consumption decreased the risk of reduced high-density lipoprotein cholesterol (HDL-C), whereas only high SSBs consumption was associated with decreased risk of high triglycerides (TG) (p < 0.05). In conclusion, high TG, reduced HDL-C and high FBG was significantly associated with high consumption of SSBs. Longitudinal studies are recommended to further investigate the extent to which SSBs influences components of MetS.

Background: Evidence is lacking on the effects of binge alcohol consumption on metabolic syndrome in the rural South African population. The purpose of this study was to investigate the association between binge drinking and components of metabolic syndrome (MetS) amongst Ellisras rural young adults aged 21 to 31 years who are part of the Ellisras Longitudinal Study. Methods: Logistic regression analysis was applied to a total of 624 participants (306 males and 318 females) aged 21 to 31 years who took part in the Ellisras Longitudinal Study (ELS). The model was adjusted for covariates, including smoking, age, and gender. Binge alcohol consumption was assessed using a standardised questionnaire that was validated for the Ellisras rural community. A standardised method of determining the components MetS was used after fasting blood samples were collected from all the participants. Results: Binge drinking remained significantly associated with low levels of high-density lipoprotein cholesterol (HDL-C) (OR = 2.64, 95% CI = 1.23–5.65), after being adjusted for smoking, age, and gender. Other MetS components were not predicted. Instead, gender remained significantly associated with all MetS components, except triglycerides, at multivariate analysis. Age retained significance at multivariate analysis with waist girth (OR = 2.13, 95% CI = 1.37–3.34), triglycerides (OR = 2.30, 95% CI = 1.05–5.02), and the MetS composite (OR = 1.65, 95% CI = 1.12–2.41). Conclusion: Binge drinking was significantly associated with lower levels of HDL-C. Future studies should investigate the relationship between alcohol abuse and the components of incident MetS in this population.
