Women's Health Questionnaire (WHQ) Baseline WHQ is a measure of mid-aged women's emotional and physical health. Consists of 36-item assessing nine domains of physical and emotional health: Depressed mood; Somatic symptoms; Anxiety/fears; Vasomotor symptoms; Sleep problems; Sexual behavior; Menstrual symptoms; Memory/concentration; and Attractiveness. Each item scored on a 4 point scale (yes definitely, yes sometimes, not much, no not at all) reduced to binary option as 0 (no) and 1 (yes). Domain subscale score was calculated as sum of domain items score divided by number of domain items. Total score was calculated as the sum of individual domain subscale score divided by number of domains. Total score range from 0 (absent) to 1 (present), with higher scores indicating more pronounced distress and dysfunction. Baseline values at different time points were considered only for the participants who were evaluable at those time points.
