This study aimed to evaluate vocal changes in pregnancy according to trimesters both objectively and subjectively.
Fifty pregnant women and 15 nonpregnant women were included in the study. Eighteen of the 50 pregnant women were in the first trimester, 17 in the second trimester, and 15 in the third trimester of their pregnancies. The fundamental frequency (F0), jitter, shimmer, noise-to-harmonics ratio (NHR), and minimum and maximum pitch were determined during acoustic voice analysis. Laryngologic examination was evaluated via reflux finding score (RFS). Voice Handicap Index 10 (VHI-10) was used for subjective analysis.
Maximum phonation time (MPT), VHI-10, and RFS were the parameters that differed significantly. MPT was significantly shorter in the third trimester. Acoustic analysis revealed that F0, jitter, shimmer, NHR, and minimum and maximum pitch values were not significantly different in any groups. RFS was higher in the first and third trimesters than the second trimester and control groups. VHI-10 scores were significantly higher in the third trimester.
Our results showed that MPT is decreased during the third trimester, although acoustic parameters did not differ. VHI-10 results deteriorated in the third trimester significantly.
本研究旨在客观和主观地评估孕期不同阶段的嗓音变化。
本研究纳入了50名孕妇和15名非孕妇。50名孕妇中，18名处于孕早期，17名处于孕中期，15名处于孕晚期。在声学嗓音分析过程中测定基频（F0）、抖动、闪烁、噪声谐波比（NHR）以及最小和最大音高。通过反流发现评分（RFS）评估喉镜检查结果。采用嗓音障碍指数10（VHI-10）进行主观分析。
最长发声时间（MPT）、VHI-10和RFS是有显著差异的参数。孕晚期MPT显著缩短。声学分析显示，F0、抖动、闪烁、NHR以及最小和最大音高值在任何组间均无显著差异。孕早期和孕晚期的RFS高于孕中期和对照组。孕晚期VHI-10评分显著更高。
我们的结果表明，尽管声学参数没有差异，但孕晚期MPT会降低。孕晚期VHI-10结果显著恶化。
