目的了解北京市西城区40岁及以上居民代谢综合征(metabolic syndrome,MS)的流行特征。方法抽取“2010年中国居民营养与健康状况监测”项目中40岁及以上人群,描述分析人群MS的流行特征,并以是否腹部肥胖进行分层分析。结果共调查421人,其中男性158人,女性263人,平均年龄(62.1±9.3)岁。MS的患病人数为113人,患病率为26.8%,其中男性患病率为27.8%,女性患病率为26.2%,男女之间患病率差异无统计学意义(2=0.13,P=0.718)。以个体为单位了解MS各组分的聚集情况,发现无、具有1项、2项、3项、4项组分的人群占比分别为17.1%、25.4%、30.6%、22.6%和4.3%。将符合诊断标准的MS人群按照不同的组合分组,发现超重/肥胖+高血糖+血脂紊乱组合患病率最高,为13.1%。按腰围标准界定肥胖,肥胖人群的总体患病率为35.8%(103/288),高于不肥胖人群7.5%(10/133)的患病率(2=36.96,P<0.001),分性别分析仍然得到相同结果。结论北京市西城区40岁及以上居民MS的患病形势较为严峻,需引起高度重视,应积极预防MS的发生,以减少心脑血管疾病的发生。
Objective To understand the prevalence of metabolic syndrome (MS) in residents aged 40 and over in Xicheng District, Beijing. Methods The population of 40 years old and above in “Monitoring the nutrition and health condition of Chinese residents in 2010” was drawn to describe the epidemiological characteristics of MS and to make stratified analysis based on whether abdominal obesity. Results A total of 421 people were investigated, including 158 males and 263 females, with an average age of 62.1 ± 9.3 years. The prevalence of MS was 113, with a prevalence of 26.8%. Among them, the prevalence rate was 27.8% in males and 26.2% in females. There was no significant difference between males and females (2 = 0.13, P = 0.718). To understand the aggregation of MS fractions on an individual basis, it was found that the percentage of people with none, one, two, three, and four components was 17.1%, 25.4%, 30.6%, 22.6% and 4.3% . The MS patients who meet the diagnostic criteria were grouped according to different combinations and found that the prevalence of overweight / obesity + hyperglycemia + dyslipidemia was the highest (13.1%). The overall prevalence of obese and obese people was 35.8% (103/288) as defined by the waist circumference, which was higher than the prevalence of 7.5% (10/133) in nonobese subjects (2 = 36.96, P <0.001) Gender analysis still yielded the same result. Conclusion The prevalence of MS in residents aged 40 years and over in Xicheng District, Beijing is relatively serious. It is necessary to pay close attention to the occurrence of MS in order to reduce the occurrence of cardiovascular and cerebrovascular diseases.
