WHO关于耳疾与听觉障碍调查方案在贵州省的实施报告

目的：在贵州省开展以人群为基础的耳疾和听力减退患病率、病因和需求的调查。方法：用容量比例概率抽样（PPS）方法对贵州省30个调查点6 626人进行听力和耳疾调查（WHO方案）。结果：听力减退患病率为17.1%,全国标准化患病率为17.6%,其中轻度11.0%,中度4.2%,重度1.4%,极重度0.5%;男性患病663人（20.2%）,女性患病468人（14.0%）。听力残疾患病率为6.1%,全国标化率6.5%;引起听力减退的可能原因：耳疾31.4%,非感染因素42.5%,遗传因素6.7%,传染病0.4%,病因不明29.3%。13.8%的调查对象需要耳科和听力学干预,助听器需求占首位（9.1%）。结论：听力减退和听力残疾患病率较过去20年明显升高,为政府制定预防和控制耳聋计划提供了科学依据。

Objective:To undertake a population-based survey on the prevalence,pathogenic factors and medical requirements of ear and hearing impairment.Method:Using the probability proportion to size(PPS) method,6626 residents were investigated in 30 clusters with the WHO protocol.Result:The prevalence of hearing impairment was 17.1%(the standardized rate: 17.6% in the whole country).Degrees of hearing impairment were mild(11.0%),moderate(4.2%),severe(1.4%),and profound(0.5%).Among them,male were 663(20.2%) and female were 468(14.0%).The prevalence of hearing disability was 6.1%(the standardized rate: 6.5% in the whole country).The causes of hearing impairment were ear disorders(31.4%),non-infectious(42.5%),genetic condion(6.7%),infectious disease(0.4%) and undetermined cause(29.3%).13.8% of person needed otology and/or audiology actions.9.1% of person needed hearing aid.Conclusion:The prevalence of hearing impairment and hearing disability is higher than last twenty years and it can provide scientific data for drawing up precaution and control strategies on deafness for government.
