滨州地区汽车驾驶员脂肪肝流行病学调查研究

目的 为了解汽车驾驶员脂肪肝患病情况及其主要的影响因素，以便采取相应的防治措施。方法 采用序贯法即健康检查→脂肪肝症状或肝功能检验指标异常→超声波（或CT）确认。结果 男性驾驶员的脂肪肝患病率为4．42％，30岁以前患病率相当低，30岁以后患病率随年龄的增长而升高，30－40岁是患病率明显升高的年龄段。常饮酒者的患病率是不常饮酒者的4．41倍，嗜酒者的患病率又是常饮酒的3．23倍。患病率虽然随驾驶员驾龄的增长而升高，但其驾龄的长短与其年龄的大小是相对应的，故不能确诊驾龄与患病有关。结论 驾驶员年龄的增长及长期超量饮酒是脂肪肝的主要致患因素，使驾驶员不饱酒或少饮应是降低患病率的有效措施。
