【摘要】 目的调查目前贵州省少数民族人群听力障碍与耳疾的流行病学情况,为该地区耳聋防治提供科学依据。方法根据WHO方案,用容量比例概率抽样方法调查贵州省30个抽样点共6626人的听力和耳疾情况,抽取调查人群中17个民族的资料进行统计分析。结果少数民族听力减退总的现患率为16.77%,其中侗族为25.93%,土家族为19.39%,白族为18.50%,苗族为15.84%,布依族为12.87%,穿青族为11.63%,其他民族为8.22%。少数民族听力残疾总现患率为6.13%,其中土家族现患率(11.03%)最高。贵州省少数民族的听力减退及听力残疾现患率与汉族(分别为17.15%和6.03%)比较差异无统计学意义(P>0.05)。少数民族耳疾现患率为17.11%,明显高于汉族(12.31%)(P<0.001),其中以分泌性中耳炎和耵聍栓塞现患率最高。中耳炎是贵州省少数民族人群听力残疾的首要病因。结论贵州省少数民族与汉族听力残疾现患率均明显高于全国平均水平,其中中耳炎致残占相当大的比例,提示有效防治中耳炎是防聋治聋的重要工作。更多还原
