彝族和汉族老年人代谢综合征患病率和相关危险因素的对比性分析

目的比较性分析四川地区彝族和汉族老年人群代谢综合征（MetS）的患病率和危险因素。方法2007年7月至8月在四川地区采用整群随机抽样的方法对20岁以上的成年人开展横断面调查，本研究选择60岁以上的彝族和汉族老年人群进行分析。诊断标准采用2006年国际糖尿病联盟（IDF）标准。结果彝族和汉族老年人群的MetS的患病率分别为23．6％和29．0％，两民族老年人群中女性MetS患病率均明显高于男性，彝族老年男性MetS患病率明显低于汉族老年男性。彝族农村老年人MetS的患病率明显低于城市，彝族农村老年人MetS的患病率明显低于汉族农村老年人。多因素logstic回归分析显示女性、年龄和城市居住是彝族老年人MetS的独立危险因素；而汉族老年人MetS的患病率仅与女性呈独立正相关。结论四川彝族和汉族老年人群MetS患病率均以女性较高，彝族城市老年人MetS患病率较高，与汉族城乡老年人患病率相当，但彝族农村老年人患病率较低，因此在彝族和汉族老年人群中应广泛且有重点的开展MetS防治策略。

Comparative analysis of prevalence and risk factors of metabolic syndrome between the elderly Yi and Han nationality population

Objective To analyze the prevalence of metabolic syndrome （MetS） and its risk factors between the elderly Yi and Han nationality population in Sichuan Province. Methods A cross-sectional survey was carded out in a representative sample of persons aged t〉20 years in Sichuan region from June 2007 to August 2007 with stratified cluster sampling method. The data of elderly Yi and Han nationality people aged 〉I 60 years were analysed. Results The prevalence of MetS in elderly Yi and Han nationality population was 23.6% and 29.0%, respectively, which were both higher in females than in males. The prevalence of MetS in male Yi people was higher, than than that in male Han people. Yi people in rural area had significantly lower prevalence of MetS than those in urban area. In rural areas, the prevalence of MetS was strikingly lower in the elderly Yi people than in Han people. Female, age and urban residence were independent risk factors for MetS in the elderly Han people, while only female was independently correlated to MetS in the elderly Yi people. Conclusion Regardless of race, the prevalence of MetS was higher in female than in male. The urban residents of Yi people had higher prevalence of MetS than in rural counterparts, whereas the gap was not noted in Han people. The implementation of health strategies needs extensive development in elderly Yi and Han population.
