甘南藏族人群代谢综合征的流行病学调查

Epidemiological survey of characteristics of metabolic syndrome in Gannan Tibetan population

目的调查甘肃省甘南藏族人群代谢综合征（Ms）的流行病学特征及相关组分的特点，了解MS分布情况，为健康教育路径选择提供依据。方法采用多级整群随机抽样方法，对甘南藏族人群进行代谢综合征横断面调查，计算患病率，检测分析MS相关组分。结果MS总患病率26．9％，男性（33．6％）高于女性（20．8％），差异有统计学意义（x2=28．770，P〈0．05）；39岁以下组、40岁一组、50岁一组以及60岁以上组患病率分别为9．9％、22．5％、27．1％和41．6％，且随着年龄增长呈现递增趋势（x2=83．220，P〈0．001），分年龄组男性患病率均高于女性，但在60岁以上组男女差异无统计学意义（x2=3．234，P〉0．05）；MS患者相关组分中高血压的患病率为75．2％，超重／月巴胖患病率为53．1％，TG偏高患病率为93．0％，血糖升高患病率为26．4％，各组分的患病率中均为HDL-C偏低的患病率最低，且男女患病率差异无统计学意义（P〉0．05）。结论甘南藏族人群MS患病率高于我国MS平均患病率水平，提示MS已成为影响甘南藏族群众生命健康的重大公共卫生问题；超重／月巴胖以及TG偏高伴随高血压已成为甘南藏族代谢综合征患病的基本特征。

Objective To investigate epidemiological characteristics of metabolic syndrome （MS） in Gannan Tibetan population, as well as to understand the epidemic situation of MS in region of Gannan and provide theoretical basis for the path of health education selection. Methods A multiple hierarchical random sampling method was taken to carry out cross-sectional survey of MS in Gannan Tibetan population, and to calculate the prevalence rates as well as the determination and analysis of MS related components. Results The overall prevalence rate of MS was 26.9%, and the male （33.6%） higher than the female （20.8%）, with statistical difference （x2=28.770, P〈0.05）. In all age group, the prevalence rates was 9.9%, 22.5%, 27.1% and 41.6% respectively, showing a increase trend with the age growing （x2=83.220, P〈0.001）. The prevalence rate in male group was higher than that in the female group among all age groups. Nevertheless, there was no statistical difference in the prevalence rates between the male and female aged 60 years or above （x2=3.234, P〉0.05）. In MS group, the prevalence rate was 75.2% of hypertension, 53.1% of overweight/obesity, 93.0% of high TG, and 21.4% of high blood glucose. In each factors of MS group, prevalence rate of HDL-C was the lowest, without statistical difference between the male and female （P〉0.05）. Conclusions MS prevalence rate in Gannan Tibetan population is higher than the average level in our country. Therefore, MS has been a major public health problem affecting human＇s lives and health in Gannan. Overweight, obesity, high TG with hypertension have become the basic traits of MS in Gannan Tibetan population
