Review of: Zaslavsky O, Rillamas-Sun E, LaCroix AZ, et al. Association between anthropometric measures and long-term survival in frail older women: observations from the Women's Health Initiative Study. J Am Geriatr Soc. 2016; 64(2):277-284.Bottom line: In frail older women, these findings suggest modestly increased mortality rates associated with BMI for underweight, decreased mortality rates for overweight and mildly obese, and no difference among the moderately or severely obese. These small differences in prognosis do not justify any change in clinical approach.
