Comparative evaluation of gustatory function between postmenopausal women and age-matched men

Area of Science:

• Gerontology
• Sensory Science
• Human Physiology

Background:

• Menopause is associated with hormonal changes that may affect sensory perception.
• Gustatory function, or taste perception, can be influenced by age and hormonal status.

Purpose of the Study:

• To investigate and compare gustatory function in postmenopausal women versus age-matched men.
• To assess differences in taste quality identification and intensity perception.

Main Methods:

• Prospective evaluation of 30 postmenopausal women and 30 age-matched men over 4 months.
• Utilized a self-assessment taste function questionnaire.
• Conducted whole mouth taste tests measuring quality identification and intensity ratings for various taste solutions.

Main Results:

• No significant differences were found in the correct identification of taste qualities (P > 0.05).
• Postmenopausal women exhibited significantly lower intensity perception for sucrose compared to other tastes (P < 0.05).
• 50% of postmenopausal women reported changes in dietary habits, favoring sweeter foods.

Conclusions:

• Postmenopausal women demonstrate a diminished perception of sucrose intensity, potentially influencing food choices.
• No significant differences in taste perception for NaCl, citric acid, or quinine hydrochloride were observed between groups.
• A notable finding was the increased preference for sweet tastes reported by 50% of postmenopausal women.
