Abstract: Objective:To estimate the prevalence of MS in elderly people aged ≥60 years and its related factors in China and provide scientific evidence for prevention and control of MS in the elderly.
Methods:Data used in this study were obtained from the 2013 Chinese Chronic Diseases and Risk Factor Surveillance Program. A total of 50 497 people aged ≥60 years were selected and interviewed through multistage stratified cluster sampling at 298 surveillance sites in 31 provinces. According to the Chinese MS diagnostic criteria proposed by the Chinese Medical Association Diabetes Branch in 2017, the prevalence rates of different MS forms were compared, and the main related factors were analyzed.
Results:The prevalence rate of MS was 36.9% (95%CI: 35.4-38.5). The prevalence rate was higher in urban area than in the rural area, higher in females than in males, higher in eastern area than in western area. The prevalence rate of MS in elderly people aged ≥70 years was lower than that in those aged 60-69 years. The rate in the elderly with higher education and income levels was higher than that in the elderly with lower socioeconomic level. The comparison of the prevalence of the five forms of MS in the elderly showed that hypertension had the highest prevalence rate (72.8%), followed by hyperglycemia (41.7%) and central obesity (37.6%). The prevalence rates of hypertriglyceridemia and low HDL-C were 25.8% and 17.5%. The risk for MS in women was 1.20 times higher than that in men. Age, gender, education level, living area and urban or rural residence were the main factors influencing the prevalence of MS. Smoking, drinking and physical activity levels were correlated with MS.
Conclusions:The risk for MS was higher in women than in men in China’s elderly population, and the risk was related to socioeconomic level and life behaviors. It is recommended to carry out lifestyle interventions, such as increasing exercise and having reasonable diet for the elderly patients with MS. Hypertension and diabetes patients also need to be treated with drugs to reduce the risk of cardiovascular disease morbidity and mortality.
