A study on the prevalence of metabolic syndrome and related factors among residents in Ningbo / 预防医学

ABSTRACT

Objective To learn the prevalence of the metabolic syndrome (MS) and related factors among 15-74 year-old residents in Ningbo. Methods Multistage random sampling method was used and 5280 residents aged 15-74 years were interviewed by trained researchers with a structured questionnaire, and physical examination and related metabolic biochemical data were collected as well. The criterion of International Diabetes Federation (IDF) and American Heart Association/National Heart, Lung and Blood Institute (AHA/NHLBI) were applied for MS diagnosis. Results The crude MS prevalence was 29.38%, and the standardized prevalence was 27.59%. The MS prevalence was a little higher in males (28.83%) than in females (26.33%) . The prevalence of MS and its components increased with age, and an abrupt increase of the prevalence of MS started at age of 55 in females. The most common combination of MS individual components was central obesity, high TG, low HDL-C and hypertension. The results of multivariate logistic regression analysis indicated that aging, smoking, family history of fat and hypertension would increase the risk of MS. Conclusion There is a high prevalence of MS in Ningbo residents. It is necessary to screen and find MS high-risk groups as soon as possible, and comprehensive measures should be adopted to reduce the incidence of MS in Ningbo as well, so as to effectively reduce the burden of type 2 diabetes and cardiovascular diseases, and to promote comprehensive health of people.
