Abstract

Background: Obesity causes changes in the vocal tract.

Aims and objectives: To investigate the impact of obesity and weight loss on voice.

Methods: The study involved 12 obese and 8 nonobese participants. Weight, body mass index, and body fat percentage were assessed. Voice parameters were measured, including maximum phonation time, fundamental frequency (F0), jitter, shimmer, and the noise-to-harmonics ratio. The Voice Handicap Index-10 was utilized for self-assessment. After 3 months, voice parameters were reassessed, and the changes were correlated with body mass index.

Results: The obese group demonstrated significant weight loss and decreased body fat percentage. Maximum phonation time was lower in the obese group but increased after weight loss. F0 did not differ between groups at baseline but increased in the obese group following weight loss. Jitter values were similar between groups but decreased in the obese group. Shimmer was higher in the obese group at both baseline and follow-up, but it showed a significant decrease. Voice handicap index-10 scores were significantly higher in the obese group and decreased markedly.

Conclusions: Obesity is linked to changes in MPT and disturbance. Dietary intervention leads to enhancements.

Significance: This is the first study evaluating the effect of losing weight with diet on voice.

减肥会影响肥胖者的语音质量吗？

背景：肥胖引起声道改变。目的和目的：研究肥胖和减肥对声音的影响。方法：研究涉及12名肥胖和8名非肥胖参与者。评估体重、身体质量指数和体脂率。测量声音参数，包括最大发声时间、基频（F0）、抖动、闪烁和噪声-谐波比。使用语音障碍指数-10进行自我评估。3个月后，重新评估语音参数，并与体重指数相关。结果：肥胖组体重明显减轻，体脂率明显下降。肥胖组的最大发声时间较低，但体重减轻后增加。F0在基线时各组之间没有差异，但肥胖组在体重减轻后增加。两组之间的抖动值相似，但肥胖组的抖动值有所下降。肥胖组的Shimmer在基线和随访中都较高，但它显示出显著的下降。肥胖组的语音障碍指数-10得分明显升高，明显下降。结论：肥胖与MPT和紊乱的改变有关。饮食干预导致增强。意义：本研究首次评价饮食减肥对语音的影响。

期刊介绍： The Journal of Craniofacial Surgery serves as a forum of communication for all those involved in craniofacial surgery, maxillofacial surgery and pediatric plastic surgery. Coverage ranges from practical aspects of craniofacial surgery to the basic science that underlies surgical practice. The journal publishes original articles, scientific reviews, editorials and invited commentary, abstracts and selected articles from international journals, and occasional international bibliographies in craniofacial surgery.
