利用B超检查对宁波市区5020人进行脂肪肝流行病学调查,共检出脂肪肝695例(13.84%)。单因素分析结果显示:饮酒、每天主食吃得多、喜吃零食、临睡前加餐、高脂饮食、睡眠过多或白天精神萎靡、经常瞌睡、糖尿病、高脂血症、肥胖是脂肪肝危险因素;而有一定劳动强度、工作压力和经常参加体育锻炼等则对脂肪肝有保护作用;进食速度快慢、是否吸烟、胆囊结石、高血压病、肝炎史与脂肪肝的发病无相关性。逐步回归分析结果显示:睡眠过多或白天精神萎靡、经常瞌睡、饮酒、高脂血症、肥胖、糖尿病、高脂饮食、每天主食吃得多、临睡前加餐是脂肪肝危险因素,而一定的劳动强度、经常参加体育锻炼则是脂肪肝的保护因素。提出必须采取行为修正、适当运动、定期查体、知识普及等综合干预措施才能收到较好效果。
