LABRANA, Ana María et al. Effects of a lower body weight or waist circumference on cardiovascular risk. Rev. méd. Chile [online]. 2017, vol.145, n.5, pp.585-594. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872017000500005.

Background: Overall and central obesity are important risk factors for cardiovascular disease. Aim: To investigate the association of body weight, body mass index (BMI) and waist circumference (WC) with cardiovascular risk factors in Chile. Material and Methods: We included 5,157 participants from the National Health Survey 2009-2010. Prevalence of type 2 diabetes, hypertension, metabolic syndrome and dyslipidemia (high total cholesterol and triglyceride levels and low HDL-cholesterol) were defined using international recommendations. BMI and WC were measured using standardized protocols. Results: A five percent lower body weight, BMI and WC were associated with a significant reduction in cardiovascular risk factors. For each 5% reduction in body weight, the risk for hypertension decreased by 8 and 9% in women and men respectively. Similar risk reductions were observed for diabetes (9 and 11% respectively), metabolic syndrome (23 and 30% respectively), low HDL cholesterol (13 and 13% respectively), high triglyceride levels (16 and 18% respectively) and total cholesterol (8 and 10% respectively). Similar findings were observed for BMI and WC. Conclusions: Lower body weight, BMI or WC are associated with important reductions in cardiovascular risk factors. A 5% reduction in these adiposity markers could be a perfectly feasible goal for lifestyle interventions.
