Although obesity is becoming a major public health problem, data are limited on the relationship between body mass index (BMI) and survival in Taiwanese populations. Therefore, the aim of this study was to evaluate the long-term effects of obesity on the risk of death from any cause and from specific diseases in middle-aged Taiwanese adults. ⋯ Increasing BMI (≥ 23 kg/m²) was positively associated with deaths from diabetes and cardiovascular diseases. We found that BMI ≥ 25 kg/m² was a significant predictor for all-cause mortality and ≥ 27 kg/m² was a significant predictor for cancer mortality. The relationship between BMI and mortality was J-shaped in Taiwanese adults.
