Hearing loss in school-aged children

Abstract

Background

Hearing loss is a common disability affecting 5% of the world’s population. A lack of opportune diagnosis affects both the individual and society. In order to develop public health policies in the field of hearing health, countries must have information about epidemiology.

Aims/Objectives

In this review, we describe the information available about prevalence and incidence of hearing loss in school-aged children.

Material and Methods

Review of the literature in PubMed.

Results

Reported prevalence of hearing loss in school-aged children varied between 0.2% and 7.8%. Several factors could explain the discrepancy in numbers such as definition of hearing loss, cause, and the inclusion of high-frequency hearing loss. The rate of delayed-onset hearing loss at the age of six years old varied between 0.6 and 0.8 per 1000.

Conclusions and Significance

The prevalence of hearing loss in school-aged children varied between 0.2% and 7.8%, and the rate of delayed-onset hearing loss at the age of six years old varied between 0.6 and 0.8 per 1000.

Chinese Abstract

背景：听力损失是一种常见的残疾, 影响着世界上 5% 的人口。及时诊断的缺乏对个人和社会都有影响。 为了制定听力健康领域的公共卫生政策, 各国必须掌握有关流行病学的信息。

目的：在本次审查中, 我们描述了有关学龄儿童听力损失的患病率和发病率的可获得信息。

材料和方法：PubMed 文献回顾。

结果：所报告的学龄儿童听力损失患病率在 0.2% 到 7.8% 之间不等。有几个因素可以解释这种差异, 例如听力损失的定义、原因和包括高频听力损失。 六岁时迟发性听力损失的发生率为每 1000 人 0.6 到 0.8 之间不等。

结论与意义：学龄儿童听力损失的患病率在0.2% 和 7.8%之间不等, 六岁时迟发性听力损失的发生率为每 1000 人 0.6 和 0.8之间不等。
