The study is a retrospective evaluation of audiometric screening tests and registration charts of 167 school children in the towns Sisimiut and Nuuk, Greenland. The children were from 5 to 14 years old. The test performed was pure tone air conduction audiometry at frequencies from 250 to 8000 Hz. In total 43% of the children had hearing thresholds exceeding hearing loss (HL) of 20 dB at one or more frequencies in either one or both ears. The threshold elevations were most common and more severe at the high frequencies (6000-8000 Hz). At the mid frequencies (500-2000 Hz) a HL greater than 20 dB was found in 32/166 (19%) of the children, seven (4%) of whom were bilaterally affected. Seventeen children (10%) had HL at two or all frequencies in the mid frequency range. HL was significantly more frequent in Sisimiut in total 95% CI = 11-40%; (p < 0.002). In Sisimiut 7/78 (9%) of the children had chronic otitis media (COM) and one had grommets. In Nuuk 5/89 (5.5%) had COM and one had congenital unilateral HL. All children with COM had HL. Audiometric screening in Greenland is indispensable for identification of children with hearing impairment and to ensure their rehabilitation.
该研究是对格陵兰西西缪特镇和努克镇167名学童的听力筛查测试及登记图表进行的回顾性评估。这些儿童年龄在5至14岁之间。所进行的测试是在250至8000赫兹频率范围内的纯音气导听力测定。总共有43%的儿童在一只或两只耳朵的一个或多个频率上听力阈值超过20分贝的听力损失（HL）。阈值升高在高频（6000 - 8000赫兹）最为常见且更为严重。在中频（500 - 2000赫兹），166名儿童中有32名（19%）的HL大于20分贝，其中7名（4%）为双侧受影响。17名儿童（10%）在中频范围内的两个或所有频率上有HL。西西缪特的HL明显更常见，总体95%置信区间 = 11 - 40%；（p < 0.002）。在西西缪特，7/78（9%）的儿童患有慢性中耳炎（COM），1名儿童有鼓膜通气管。在努克，5/89（5.5%）有COM，1名儿童有先天性单侧HL。所有患有COM的儿童都有HL。在格陵兰进行听力筛查对于识别听力受损儿童并确保他们的康复是必不可少的。
