Adjusted cross-sectional association between body mass index and the risk of vasomotor symptoms at baseline, stratified by menopausal status at baseline (premenopause: n=4,169; perimenopause: n=5,881; postmenopause: n=4,109). Relative risk ratio (RRR) and their 95% confidence intervals (95% CI) were adjusted for use of menopausal hormone therapy, race/ethnicity/region, education, and smoking status at baseline.
