目的探讨农村体检人群脂肪肝患病率及相关危险因素。方法对41 677例农保体检人员的体检结果进行系统分析,统计不同年龄、性别体检人群脂肪肝患病率及其与血脂、血压、血糖、肥胖等多因素之间的关系。数据SPSS 16.0统计软件统计分析。计量资料采用t检验,计数资料采用χ2检验,采用二项分类logistic回归进行多因素回归分析,以P<0.05为差异有统计学意义。结果农村体检人群脂肪肝总患病率为14.70%,男女间差异无统计学意义,年龄层分布男性以40~49岁组最高,女性以60~69岁组最高。脂肪肝患病风险随血脂、血糖、血压、体质指数的增高而显著增加(P<0.05),尤以肥胖最为显著。脂肪肝患病率与血脂成分相关,混合型高脂血症组最高,单纯性高甘油三酯血症组次之,单纯性高胆固醇血症组最低。结论农村体检人群脂肪肝患病率为14.70%,高血脂、高血糖、高血压、肥胖是脂肪肝发病的危险因素,应加强对脂肪肝的预防及相关危险因素的监测。
Objective To investigate the prevalence of fatty liver and related risk factors in rural medical examination population. Methods The physical examination results of 41 677 rural health insurance medical personnel were systematically analyzed. The prevalence of fatty liver and its relationship with the factors of blood lipids, blood pressure, blood glucose and obesity in different age and gender physical examination population were statistically analyzed. Data SPSS 16.0 statistical software statistical analysis. Measurement data using t test, count data using χ2 test, the use of binary logistic regression multivariate regression analysis to P <0.05 was considered statistically significant. Results The total prevalence of fatty liver in rural population was 14.70%. There was no significant difference between male and female. The age distribution of male was the highest in 40-49 years old group and the highest in female aged 60-69 years group. The risk of fatty liver significantly increased with the increase of blood lipids, blood glucose, blood pressure, body mass index (P <0.05), especially the most significant obesity. The prevalence of fatty liver was related to the lipid composition, the highest in mixed hyperlipidemia group, the second in simple hypertriglyceridemia group, and the lowest in simple hypercholesterolemia group. Conclusion The prevalence of fatty liver in rural population is 14.70%. Hyperlipemia, hyperglycemia, hypertension and obesity are the risk factors of fatty liver disease. Prevention of fatty liver and the monitoring of related risk factors should be strengthened.
