Epidemiology and clinical outcomes of vasomotor symptoms among perimenopausal women and women aged 65 years or older in the US: a systematic review.

Vasomotor symptoms (VMS) are the hallmark of menopause and negatively affect a large proportion of women over many years. However, studies evaluating the overall impact of VMS are limited. This systematic review (SR) aimed to examine epidemiological, clinical, humanistic, and economic outcomes of VMS among perimenopausal women and among women aged ≥65 years in the US. A systematic search of the MEDLINE and Embase databases was conducted to identify observational studies (2010-2022) reporting on these populations. Data reporting outcomes of interest were extracted and analyzed descriptively. Of 7,613 studies identified, 34 met inclusion criteria, of which 30 reported on perimenopausal women and 4 reported on VMS in women aged ≥ 65 years. VMS and severe/moderate-to-severe VMS were reported by 48.4-70.6 percent and 13.0-63.1 percent, respectively, of perimenopausal women. Mean VMS duration was 2.6 years, and median duration ranged from 7.4 to 10.1 years among women with onset in early perimenopause and from 3.8 to 6.1 years among those with onset in late perimenopause. Among women aged ≥65 years, 20.9-45.1 percent reported VMS; 2.0 percent reported severe symptoms, and 17.6 percent reported moderate symptoms. No studies reported VMS frequency and duration or the economic or humanistic burden among women aged ≥65 years. In conclusion, high VMS frequency and severity were observed among perimenopausal women and women aged ≥65 years in the US in this SR, highlighting the need for (1) better management of VMS to reduce frequency and severity and (2) further research to clarify the impact of VMS on disease burden, quality of life, and economic impact.
