Pediatric vocal fold pathology is important because having a healthy voice free from disorders is crucial in a child's emotional and educational development.
To determine whether there is an association between singing in a children's choir and the development of voice disorders.
DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study of children (aged 8 to 14 years) singers selected from local children's choirs and nonsingers selected from local schools evaluated at Clarós Otorhinolaryngology Clinic in Barcelona, Spain, from October 2016 through April 2018.
Singing for a mean time of 7.5 hours per week for 2.5 years.
The primary outcome of the study was the prevalence of voice disorders measured using videostroboscopy. The obtained values were analyzed statistically and used to compare the characteristics of the children and the frequency of voice disorders between the groups.
Of 1495 enrolled children (745 male [49.8%]; median age, 9.3 years [range, 8-14 years]), 752 were singers and 743 were nonsingers. No differences in baseline characteristics were observed between the groups. Voice disorders were more frequent in the nonsinging group than in the singing group (32.4% vs 15.6%; difference, 16.8%; 95% CI, 12.3%-21.4%). Of 12 voice disorders considered in this study, all 12 were more frequent in the nonsinging group. Functional voice disorders were more frequent in the nonsinging group than in the singing group (20.2% vs 9.4%; difference, 10.8%; 95% CI, 7.2%-14.3%), as were organic voice disorders (12.2% vs 6.1%; difference, 6.1%; 95% CI, 2.6%-9.6%).
Voice disorders were less common among children in the cohort who sing in choirs, possibly because of voice training and the commonly observed habit of attending regular ear, nose, and throat examination. Voice disorders may be prevented in nonsinging children if the same solicitude for voice is observed.
儿科声带病变很重要，因为拥有一个健康、无嗓音障碍的声音对于儿童的情感和教育发展至关重要。
确定儿童合唱团唱歌与嗓音障碍发展之间是否存在关联。
设计、设置和参与者：这是一项前瞻性队列研究，在西班牙巴塞罗那的克拉罗斯耳鼻喉科诊所评估了从当地儿童合唱团中选择的 8 至 14 岁儿童歌手（共 752 名）和从当地学校中选择的非歌手（共 743 名），研究时间为 2016 年 10 月至 2018 年 4 月。
每周平均唱歌时间为 7.5 小时，时长 2.5 年。
该研究的主要结果是使用频闪喉镜测量嗓音障碍的患病率。对获得的值进行了统计学分析，并用于比较两组儿童的特征和嗓音障碍的频率。
共纳入 1495 名儿童（男 745 名[49.8%]；中位年龄 9.3 岁[范围 8-14 岁]），其中 752 名为歌手，743 名为非歌手。两组儿童的基线特征无差异。非歌手组的嗓音障碍发生率高于歌手组（32.4%比 15.6%；差异为 16.8%；95%CI 为 12.3%-21.4%）。在所考虑的 12 种嗓音障碍中，所有 12 种在非歌手组中更为常见。非歌手组的功能性嗓音障碍发生率高于歌手组（20.2%比 9.4%；差异为 10.8%；95%CI 为 7.2%-14.3%），器质性嗓音障碍发生率也高于歌手组（12.2%比 6.1%；差异为 6.1%；95%CI 为 2.6%-9.6%）。
合唱团唱歌的儿童中嗓音障碍发生率较低，这可能是由于声音训练和经常进行耳部、鼻部和喉部常规检查的习惯。如果对非歌手儿童也给予同样的关注，可能会预防嗓音障碍。
