目的探讨煤矿井下工人脂肪肝发病情况及与体力劳动、膳食营养状况的关系。为脂肪肝的防治提供科学依据。方法采用食物频数问卷法对206名煤矿井下作业工人和169名井上工人进行膳食调查和体格检杳,以肝脏超声检查确定脂肪肝发病并进行统计分析。结果某矿区从事极重体力劳动的井下作业工人脂肪肝的发病率为8.25%,从事轻体力劳动的井上工人脂肪肝的发病率为14.79%。两者间差异有统计学意义(P<0.05)。井下和井上工人膳食中食用油的摄入分别为37和43g,均显著高于中国营养学会推荐的参考摄入量(<25g)。蔬菜、水果的摄入量分别为240、251和83、92g,低于中国营养学会推荐的参考摄入量。相应的2组工人能量的摄入均高于每日营养素供给量标准(RNI),维生素B2、维生素C、Ca等营养素的摄入低于RNI,2组间差异无统计学意义(P>0.05)。结论从事极重体力劳动的煤矿井下作业工人脂肪肝的发病率低于从事轻体力劳动的井上工人。两者的膳食中食用油的摄入量大大高于中国营养学会推荐的参考摄入量,蔬菜、水果的摄入量又低于中国营养学会推荐的参考摄入量。提示煤矿工人应注意调整膳食结构,同时井上工人应加强体育锻练,减少脂肪肝的发生。
Objective To investigate the incidence of fatty liver in coal miners and its relationship with manual labor and dietary nutrition. To provide a scientific basis for the prevention and treatment of fatty liver. Methods The food frequency questionnaire method was used to investigate the dietary and physical examination of 206 coal miners and 169 workers in the well. The incidence of fatty liver was determined by liver ultrasonography and statistical analysis was made. Results The incidence of fatty liver was 8.25% in downhole workers engaged in heavy manual labor in a mining area, and 14.79% in uphole workers engaged in light manual labor. The difference between the two groups was statistically significant (P <0.05). The intake of cooking oil in downhole and uphole workers was 37 and 43g, respectively, which were significantly higher than the reference intake (<25g) recommended by the Chinese Nutrition Society. Vegetables, fruits intake were 240,251 and 83,92 g, respectively, lower than the Chinese Society of Nutrition recommended reference intake. The corresponding two groups of workers’ energy intake were higher than the daily nutrient supply standard (RNI), and the intake of nutrients such as vitamin B2, vitamin C and Ca was lower than that of RNI (P> 0.05 ). Conclusions The incidence of fatty liver in underground coal miners engaged in heavy manual labor is lower than that of workers in light manual labor. The intake of edible oil in both meals is much higher than the reference intake recommended by the Chinese Nutrition Society. The intake of vegetables and fruits is lower than the reference intake recommended by the Chinese Nutrition Society. Tip coal miners should pay attention to adjust the diet, while Inoue workers should strengthen physical exercise to reduce the occurrence of fatty liver.
