目的为了探讨脂肪肝的发生与年龄、性别等因素的关系。方法对益阳市城区28个单位4586例干职工进行健康体检、B 超及实验室检测调查。结果益阳市域区被检单位人群平均患病率为17.31%:其中①30岁以下组男性脂肪肝患病率为11.66%,女性为3.04%,两组比较 P<0.01(X2=28.974);②31-45岁组男性脂肪肝患病率为24.46%,女性为5.94%,男女比较 P<0.01(X2=30.491);③45岁以上男女脂肪肝患病率剧增,且达同一水平分别为37.68%和39.90%,P>0.05(X2=0.95):④脂肪肝患者有75%的血脂显著高于非脂肪肝者 P<0.01(X2=90.306):⑤脂肪肝患者82%ALT 显著高于非脂肪肝者 P<0,01(X2=209.584):⑥血糖升高者15.5%,与同期非脂肪肝体检者4%比较 P<0.01(X2=14.558)。结论脂肪肝的发生与年龄、性别密切相关,其患病率随年龄长而增加,男性患病率有趋向年轻化的现象;女性脂肪肝的发生可能尚与内分泌功能紊乱有关。
Objective To explore the occurrence of fatty liver and age, gender and other factors. Methods A total of 4586 workers in 28 units in Yiyang City were investigated by physical examination, B-ultrasound and laboratory tests. Results The average prevalence rate was 17.31% in Yiyang urban area. Among them, ①the prevalence of fatty liver was 11.66% in male under 30 years old and 3.04% in female group, P <0.01 (X2 = 28.974); ②31- The prevalence of fatty liver in 45-year-old men was 24.46% and in female was 5.94%, P <0.01 for men and women (χ2 = 30.491). ③The prevalence of fatty liver in men and women over 45 years old increased sharply and reached the same level of 37.68% 39.90%, P> 0.05 (X2 = 0.95): ④ 75% of fatty liver patients had significantly higher serum lipids than non-fatty liver patients (P <0.01, X2 = 90.306): ⑤ 82% of patients with fatty liver ALT was significantly higher than non-fatty liver P <0,01 (X2 = 209.584): ⑥ 15.5% of those with elevated blood glucose, P <0.01 compared with 4% of non-fatty liver subjects in the same period (X2 = 14.558). Conclusions The occurrence of fatty liver is closely related to age and sex. The prevalence of fatty liver increases with age. The prevalence of fatty liver tends to be younger. The incidence of fatty liver in women may still be related to endocrine dysfunction.
