To describe personal listening device (PLD) usage and sociodemographic variables among a nationally representative sample of Canadians and examine audiometric outcomes among a subsample.
Audiometry and in-person questionnaires were used to evaluate hearing and PLD usage across age, sex, household income/education level. PLD exposure was quantified using a common occupational noise limit.
A randomised sample of 10,460 respondents, aged 6-79, with audiometric analysis of a subsample (n = 4807), aged 6-29, tested between 2012 and 2015.
Loud PLD usage was reported by19.5% of Canadians. The highest prevalence was among teenagers (44.2%) and young adults (36.3%). Among children, 13.1% of users listened at loud volumes. High PLD usage (equivalent to or above 85 dBA, LEX 40) among 12-19 year olds was double that of 20-29 year olds: 10.2% versus 5.1%. Five years or more of loud PLD usage was associated with significantly higher mean hearing thresholds compared to less years. No association between loud or high PLD usage and mean thresholds were found.
The majority used PLDs safely, however a small proportion reported high risk usage which will impact hearing should this pattern persist over many years.
描述加拿大全国代表性样本中个人听力设备(PLD)的使用情况和社会人口统计学变量,并检查子样本中的听力测试结果。
使用听力测试和现场问卷评估年龄、性别、家庭收入/教育水平等方面的听力和 PLD 使用情况。使用常见的职业噪声限值来量化 PLD 暴露。
2012 年至 2015 年间,对 10460 名年龄在 6-79 岁的随机抽样受访者进行了听力分析,其中 4807 名年龄在 6-29 岁的受访者进行了子样本测试。
19.5%的加拿大人报告使用了大声的 PLD。青少年(44.2%)和年轻人(36.3%)的使用率最高。在儿童中,13.1%的使用者听音量很大。12-19 岁的青少年中,高 PLD 使用(相当于或高于 85 dBA,LEX 40)的比例是 20-29 岁青少年的两倍:10.2%比 5.1%。与使用年限较短的人群相比,使用大声或高音量 PLD 超过 5 年与平均听力阈值显著升高相关。大声或高音量 PLD 使用与平均阈值之间没有关联。
大多数人安全地使用 PLD,但一小部分人报告了高风险的使用情况,如果这种模式持续多年,这将对听力产生影响。
