船员脂肪肝发病情况的流行病学分析

目的了解船员人群脂肪肝发病情况，为船员健康提供指导。方法对2003～2007年到福建国际旅行卫生保健中心体检的1078例船员（18～50岁）进行调查，并选择相同年龄段的1175例非船员（男性）体检者作为对照，根据B超对脂肪肝诊断的分级标准进行对比分析。结果18～30岁年龄段脂肪肝发生率较轻，发生率船员组是3．0％、对照组是2．6％，两者无统计学上的差异（P〉0．05）；31～40岁年龄段和41～50岁年龄段脂肪肝的发生率，船员组分别是35．0％和45．6％，对照组分别是28．0％和35．8％，两个年龄组均有统计学上的差异（P〈0．05），且差异主要集中在中度脂肪肝上。结论31～50岁海员脂肪肝的发生率高于一般人群，且程度更为严重。
