目的探讨广州市海珠区中老年人行为生活方式与代谢综合征(MS)的相关性,为MS的综合防治提供科学依据。方法采用多阶段整群抽样方法,随机抽取海珠区45岁及以上社区居民进行问卷调查,调查其行为生活方式,对人群进行体格检查和血液生化指标检测,采用logistic回归分析方法分析MS相关的行为生活方式高危因素。结果共调查2 212人,其中男性952人,女性1 260人,年龄45~88岁,平均年龄为(59±10)岁。以初中及以下学历为主,占59.99%。MS共639例,MS总患病率为28.89%,其中男性MS患病率为29.52%,女性MS患病率28.41%,差异无统计学意义(P>0.05)。对年龄、文化程度因素进行校正,多因素logistic回归分析发现,相对于不吸烟者,吸烟者患MS的风险更高(OR值为1.61);相对于摄入新鲜蔬菜<200 g/d的人群,摄入200~399和≥400 g/d人群患MS可能性更低(OR值分别为0.55、0.15)。结论 MS的发生可能与吸烟、新鲜蔬菜摄入量相关,提示可采取控烟和增加新鲜蔬菜摄入量预防MS的发生。 Objective To explore the correlation between behavioral lifestyle and metabolic syndrome (MS) among middle-aged and elderly people in Haizhu District of Guangzhou City, and to provide a scientific basis for the comprehensive prevention and treatment of MS. Methods A multistage cluster sampling method was used to randomly select community residents aged 45 years and older in Haizhu District to conduct questionnaire survey and investigate their behavioral life style. Physical examination and blood biochemical indexes were tested in the population. Logistic regression analysis was used to analyze MS-related behaviors Lifestyle risk factors. Results A total of 2 212 people were investigated, including 952 males and 1260 females, aged 45-88 years, with an average age of (59 ± 10) years. Primarily junior high school and below, accounting for 59.99%. There were 639 cases of MS with a total prevalence of 28.89%. The prevalence of MS was 29.52% in male and 28.41% in female. There was no significant difference (P> 0.05). Multivariate logistic regression analysis showed that smokers had a higher risk of MS compared with non-smokers (odds ratio was 1.61), compared with those who consumed less than 200 g / d of fresh vegetables , MS patients with 200 ~ 399 and ≥400 g / d intake were less likely to have MS (OR = 0.55 and 0.15, respectively). Conclusions The occurrence of MS may be related to the intake of smoking and fresh vegetables, suggesting that tobacco control and increased intake of fresh vegetables can prevent the occurrence of MS.
