Abstract: Objective To study the general characteristics of the over 50-year old populations withoverweight and obesity in Changsha; to further provide the basis in exploring interventionmeasures accordingly.Methods Using stratified cluster random sampling, 20 communities were selected from TianxinDistrict of Changsha as the investigation subjects. In each sample, the correlation study ofoverweight and obesity were conducted among the over 50-year old permanent residents, and thehypertensive distribution in different body weight groups of the population was investigated atthe same time.Results The prevalence rate of overweight was 38.9%, and with male being 46.8%, female being33.1%, and that of obesity was 6.1%, with male being 7.1%, female being 5.3%, respectively. Theprevalence rate between men and women in terms of overweight and obesity demonstrated astatistical significance. The prevalence rate of overweight in 60-69 years old group was higherthan that in 50-59 and 70-90 years old groups(P =0.032, 0.005). As multiple linear regressionshowed that age, gender, labor intensity, smoking, drinking were significantly associated withbody mass index(BMI), which was positively correlated with hypertension.Conclusion The prevalence of overweight and obesity in Changsha showed higher among theelder populations. especially in male. Age, sex, labor, smoking and drinking are predominantinfluences in BMI which implies that a comprehensive intervention should be taken to decreaseoverweight and obesity in populations, it plays an important role in the incidence of hypertensionreduction.
