Vocal Symptoms and Acoustic Findings in Menopausal Women in Comparison to Pre-menopause Women with Body Mass Index as a Confounding Variable

OBJECTIVES: To compare the prevalence of phonatory symptoms in menopausal women compared to pre-menopause women with body mass index (BMI) as a confounding variable. METHODS: A total of 69 women, 34 menopausal and 35 pre-menopausal were invited to participate in this study. Demographic variables included age, smoking, and BMI. All subjects were asked about the presence hoarseness, loss of high or low frequencies, pitch breaks, throat clearing, dryness in the throat and vocal fatigue. Acoustic analysis was performed and the Voice Handicap Index (VHI)-10 was filled by all the subjects. RESULTS: There was a significantly higher prevalence of throat clearing and dryness in the menopausal group compared to the pre-menopause group with a P value of 0.035 and 0.032 respectively. When BMI was taken into account, there was no statistically significant difference in the prevalence of any of the phonatory symptoms in menopausal women with high BMI and pre-menopause. There was no statistically significant difference in the means of any of the acoustic parameters between the menopausal group and pre-menopausal group. There was no significant difference in the mean VHI-10 between the menopause group and the pre-menopause (P = 0.652). CONCLUSIONS: The results of this investigation substantiate the importance of fat as an alternative source of estrogen which can mask some of the phonatory symptoms.
