Analysis of cardiovascular risk factors for middle aged and elderly people over 40 years old in Kunming

Abstract

Objective To assess the prevalence of cardiovascular disease and its risk factors in middle-aged and elderly population in Kunming area. Methods A cross-sectional population survey was carried out by stratified cluster sampling. A total of 36 483 Kunming residents over 40 years old were interviewed and physically examined during the period from 2014 to 2016. The adjusted prevalence odds ratio was calculated for the association of coronary heart disease/stroke with its cardiovascular risk factors in multivariate logistic regression models. Results The self-reported rate of the total original records of participants with coronary heart disease was 6.1% (95%CI: 5.5%-6.8%), which was higher than that of stroke patients [3.7% (95%CI: 3.4%-4.0%)]. The age specific prevalence of diabetes, hypertension, overweight and obesity were 8.6%, 47.2%, 43.2% and 15.1%, respectively. The prevalence of hypertension in men was higher than that in women (P=0.042), while the prevalence of diabetes, overweight and obesity in women was higher than that in men (P<0.05). In addition, the prevalence odds ratio (95%CI) of diabetes, obesity, stage 1 and stage 2 hypertension for coronary heart disease were 2.50(2.30-2.76), 1.53(1.38-1.69), 1.14(1.00-1.28) and 1.35(1.20-1.52), and for stroke were 2.22(1.96-2.49), 1.25(1.10-1.45), 1.41(1.22-1.68) and 1.69(1.44-2.00) respectively in the multivariate logistic regression models. Conclusions The prevalence of cardiovascular disease and its associated several cardiovascular risk factors among middle-aged and elderly people in Kunming area is high, which might pose bring serious challenges to the health care system.
