Association of Later-Life Weight Changes With Survival to Ages 90, 95, and 100: The Women’s Health Initiative

Abstract Background Associations of weight changes and intentionality of weight loss with longevity are not well described. Methods Using longitudinal data from the Women’s Health Initiative (N = 54 437; 61–81 years), we examined associations of weight changes and intentionality of weight loss with survival to ages 90, 95, and 100. Weight was measured at baseline, year 3, and year 10, and participants were classified as having weight loss (≥5% decrease from baseline), weight gain (≥5% increase from baseline), or stable weight (
