Abstract

Objective: The aim of this study was to investigate the effect of fasting on voice performances.
Methods: This study was performed between June 2015 and July 2015. The study group comprised 26 subjects who regularly fasted during Ramadan. These subjects comprised 14 males and 12 females, with an average age of 36±10.15 years. The objective and subjective analyses of voice were performed twice before Ramadan and during the month of Ramadan (after 15 days). Acoustic voice analysis (F0, jitter %, and shimmer %) was performed for the objective analysis, and Voice Handicap Index (VHI)-30 questionnaire was used for the subjective analysis. Subjects were compared for F0, jitter %, shimmer %, and VHI-30 scores before and during Ramadan.
Results: Before Ramadan, mean F0 was 201.07±54.17 Hz and mean jitter % was 0.37±0.19, whereas during Ramadan, mean F0 was 179.07±50.09 Hz and mean jitter % was 0.63±0.22, and both parameters showed a statistically significant difference (p<0.001 and p<0.001, respectively). Shimmer % and VHI-30 scores were lower before Ramadan than those during Ramadan, but the differences were not statistically significant.
Conlusion: Fasting adversely affected the objective voice parameters; however, no significant changes were observed in the subjective voice parameters.
