目的:明确舟山地区渔民群体脂肪肝的患病情况及主要危险因素。方法:通过随机多级分层整群抽样方法对舟山男性渔民进行调查。结果:3246名渔民脂肪肝检出率为24.37%。酒精性、可疑酒精性、非酒精性脂肪肝占脂肪肝的比例分别为38.05%、14.54%、47.41%。青年组、中年组、老年组的脂肪肝患病率分别为14.87%、32.73%、25.30%,两两之间均存在统计学意义(P<0.01)。脂肪肝组的高血压等患病率及空腹血糖等生化指标均高于非脂肪肝组(P<0.01)。多因素非条件Logistic回归分析显示,年龄、高血脂症、2型糖尿病、高血压、饮酒均为脂肪肝发病的危险因素(P<0.01或P<0.05)。结论:中老年渔民脂肪肝的患病率较高,渔民群体中年龄、饮酒、糖脂代谢紊乱与脂肪肝的关系更为密切。
Objective: To clarify the prevalence and major risk factors of fatty liver in fishermen population in Zhoushan. Methods: Male fishermen in Zhoushan were investigated by randomly stratified cluster sampling method. Results: The detection rate of fatty liver in 3246 fishermen was 24.37%. Alcoholic, suspicious alcoholic and non-alcoholic fatty liver accounted for 38.05%, 14.54% and 47.41% respectively. The prevalence of fatty liver in youth group, middle age group and elderly group were 14.87%, 32.73% and 25.30%, respectively, with statistical significance (P <0.01). The prevalence of hypertension and fasting blood glucose in fatty liver group were higher than those in non-fatty liver group (P <0.01). Multivariate non-conditional logistic regression analysis showed that age, hyperlipidemia, type 2 diabetes mellitus, hypertension and alcohol consumption were the risk factors of fatty liver disease (P <0.01 or P <0.05). Conclusion: The prevalence of fatty liver among middle-aged and elderly fishermen is high, and the relationship among age, alcohol consumption, dyslipidemia and fatty liver of fishermen is more closely related to fatty liver.
