摘要：Obesity has important health hazards, and the epidemic seems to be growing in developed countries. There is scientific evidence for higher risk of earlier death among the obese.

Key issues are clarity in the definition of the effect under study, confounding, measurement error and a phenomenon sometimes termed reverse causality in which obesity causes some diseases, but some of the diseases also affect adiposity and mortality
