Central obesity in elderly individuals in south-western Saudi Arabia: prevalence and associated morbidity

Central obesity in all individuals aged 65 years and over [n = 810] in the catchment areas of three primary health care centres in Abha was determined from the waist circumference [WC] and waist-to-hip ratio [WHR]. The age-adjusted prevalence of central obesity was 32.4% and 43.5% based on the WC and WHR indicators respectively. WC was significantly associated with the risk of diabetes and hypertension, while WHR was significantly associated with the risk of diabetes only. These findings suggest that reducing the prevalence of central obesity in old age would decrease the risk of diabetes and hypertension. WC is a powerful independent predictor mainly of hypertension risk, while WHC is a good predictor of the risk of diabetes
