北京市劳模脂肪肝调查及相关因素分析

Investigation and Analysis on Prevalence of Fatty Liver and Its Related Factors among Model Workers in Beijing

目的了解北京市劳模脂肪肝的患病情况及与体重指数(BMI)、血脂水平等相关因素的关系,为改善劳模健康状况提供依据。方法收集北京市劳模体检者3 408例,根据体检结果以及肝脏B超结果分为2组,脂肪肝组1 971例和非脂肪肝组1 437例,并进行生活问卷调查,比较分析脂肪肝的相关因素。结果劳模人群脂肪肝检出率为57.83%;男性脂肪肝检出率为62.59%,高于女性的40.06%,46岁以上劳模的脂肪肝检出率为63.02%,高于30～45岁的47.06%,差异均有统计学意义(p<0.05)。脂肪肝组高血压、高脂血症、超重/肥胖检出率高于非脂肪肝组,差异有统计学意义(p<0.01);工作与社会压力大、生活不规律、过度劳累、运动减少、经常在外就餐、高脂饮食人群脂肪肝的检出率高达52.32%～80.20%。结论劳模脂肪肝的总体患病率较高,并存在性别与年龄差异。BMI增高、高脂血症与脂肪肝高度相关,BMI增高有助于预测脂肪肝的发病风险。改变不良生活方式是防治脂肪肝的关键。

Objective To have knowledge about the prevalence of fatty liver among model workers in Beijing and its correlation with related factors such as body mass index（BMI） and blood lipid level so as to provide a basis for improving health state of model workers.Method 3 408 model workers in Beijing who had physical examination were collected and divided into two groups according to results of their physical examination and liver B-ultrasound.1 971 cases in the group with fatty liver and 1 437 cases in the group without fatty liver were surveyed with questionnaire concerning life habits and related factors of fatty liver were comparatively analyzed.Results The detection rate of fatty liver in the model worker group with fatty lever was 57.83%;the detection rate of fatty liver in the males was 62.59% which was higher than that of 40.06 % in the females and that in model workers aged over 46 years old was 63.02% which was higher than that of 47.06% in model workers aged 30~45 years old,and the differences were statistically significant（p0.05）.The detection rate of hypertension,hyperlipidemia,overweight/obesity in the group with fatty liver was higher than that in the group without fatty liver,and the differences were statistically significant（p0.01）;the detection rate of fatty liver in people who had high working and social pressure,irregular lifestyle,overwork,reduced exercise,frequent eat-out,high-fat diet was as high as 52.32%~80.20%.Conclusion The total prevalence of fatty liver among model workers is relatively high which varies by sex and age.The increase of BMI,hyperlipidemia is highly correlated with fatty liver and the increase of BMI is helpful in predicting the risk of fatty liver.Changing unhealthy lifestyle is crucial to prevent and treat the fatty liver.
