Abstract: Objectives: To examine the relationship between body mass index (BMI) and subjective well-being (SWB) among long-lived women over 95 years of age and evaluate whether this relationship is mediated by functional ability. Design: Retrospective cohort study. Setting: Data from the Rugao longevity cohort, a population-based study in Rugao, China. Participants: A sample of 342 long-lived women (mean age 97.4 ± 2.1, range 95–107) whose SWB and other covariates were available were included in this study. Measurements: BMI was calculated as weight in kilograms divided by height in meters-squared (kg/m2). SWB was measured by life satisfaction (LS), positive affect (PA), negative affect (NA) and affect balance (AB). Functional ability was assessed by the Katz Index of Activities of Daily Living (ADL). Results: According to BMI classification standards for China, the underweight group had lower levels of LS than the normal and overweight groups (28.62 vs. 30.51 and 31.57, respectively; p
