Determinants of age at natural menopause in the Isparta Menopause and Health Study: premenopausal body mass index gain rate and episodic weight loss

Objective: The influence of body weight and weight change on age at natural menopause (ANM) is controversial. We aimed to explore these associations by overcoming two possible reasons for inconsistent findings: (1) a lack of information on weight change from a fixed time point up until menopause and (2) a possibility of capturing a spurious association between later ANM and greater weight gain because of a longer time span.
