What this trial studies
The purpose of this study is to estimate the prevalence of Vasomotor Symptoms (VMS) and prevalence of moderate to severe VMS in peri-menopausal women and post-menopausal women aged 40-65 in East Asia (China, South Korea and Taiwan) and the proportion of the following subpopulations: Hormone Replacement Therapy (HRT)-eligible and willing to take HRT; HRT-eligible and HRT-averse (i.e. not willing to take HRT); HRT-ineligible due to contra-indications/high-risk; and HRT-stoppers. The study will also assess Health Related Quality of Life (HRQoL) and VMS related productivity loss among perimenopausal and post-menopausal women with moderate-to-severe MR-VMS and the respondents' attitudes toward prescription treatments.

Outcome measures
Primary outcomes
- Prevalence of Vasomotor Symptoms (VMS) in peri-menopausal women and post-menopausal women aged 40-65 (1 day (once through survey))
Prevalence of VMS in peri-menopausal women and post-menopausal women aged 40-65. Peri-menopause is defined as changes in the regular period in terms of irregularity in the length of the period, the time between periods, and the level of flow. Post-menopause is defined as spontaneous amenorrhea over 12 months. - Prevalence of moderate-to-severe Vasomotor Symptoms (VMS) in peri-menopausal women and post-menopausal women aged 40-65 (1 day (once through survey))
Prevalence of moderate-to-severe Vasomotor Symptoms (VMS) cases in peri-menopausal women and post-menopausal women aged 40-65 will be evaluated. - Severity of Vasomotor Symptoms (VMS) symptoms based on pre-defined definitions for severity among peri-menopausal women and post-menopausal women aged 40-65 (1 day (once through survey))
Severity of Vasomotor Symptoms (VMS) in peri-menopausal women and post-menopausal women aged 40-65 will be evaluated following the Food and Drug Administration (FDA) Guidelines. The severity of VMS symptoms may range from: absence of symptoms (no sensation of heat or sweating), mild (the sensation of feeling hot without sweating), moderate (the sensation of feeling hot, accompanied by sweating, and able… - Proportion of participants Hormone Replacement Therapy (HRT) eligible and willing to take HRT (1 day (once through survey))
Number of participants eligible and willing to take Hormone Replacement Therapy (HRT) compared to number of participants evaluated. - Proportion of participants Hormone Replacement Therapy (HRT) eligible and HRT averse (1 day (once through survey))
Number of participants eligible and not willing to take Hormone Replacement Therapy (HRT) compared to number of participants evaluated.
