【摘要】 目的运用流行病学调查手段,探讨不同性别、年龄人群体质量指数(bodymassindex,BMI)与脂肪性肝病的关系,以期为早期干预及改善脂肪性肝病预后提供依据。方法对2003年上半年深圳地区企事业单位的5571例健康体检者按BMI分为正常组、超重组、肥胖组进行腹部B超、肝功能的检查,对其结果进行统计分析。结果①肥胖症总发生率32.01%,其中男性42.45%,女性16.53%。②男女各年龄组脂肪肝的检出均随着BMI的增加而显著增加(χ2=32.953～380.177,P<0.01)。③男性组总脂肪肝合并谷丙转氨酶异常的检出率随着BMI的增加而增加(χ2=7.635,P<0.05),但各年龄组间差异无显著性意义(P>0.05)。结论肥胖是导致脂肪性肝病的主要因素。更多还原
