最近的研究表明，肥胖率上升将限制美国未来预期寿命的增长，并且与其他高收入国家相比，肥胖是造成当前美国寿命不足的一个重要原因。肥胖对当前和未来国家层面死亡率模式的贡献的估计对于个体层面肥胖与死亡率之间关联程度的估计很敏感。我们使用三个长期运行的美国数据源：弗雷明汉心脏研究、国家健康和营养检查调查以及国家健康访谈调查，评估了 1948 年至 2006 年间中年人群肥胖/死亡率关联的长期趋势。我们发现，随着时间的推移，肥胖与总体死亡率之间的关联程度大幅下降，在某些情况下，还与心血管特异性死亡率之间的关联程度显着下降。我们的结论是，估计肥胖对当前国家层面死亡率模式的贡献应考虑到最近肥胖与死亡率关联程度的下降。
Recent research suggests that rising obesity will restrain future gains in US life expectancy and that obesity is an important contributor to the current shortfall in us longevity compared to other high‐income countries. Estimates of the contribution of obesity to current and future national‐level mortality patterns are sensitive to estimates of the magnitude of the association between obesity and mortality at the individual level. We assessed secular trends in the obesity/mortality association among cohorts of middle‐aged adults between 1948 and 2006 using three long‐running US data sources: the Framingham Heart Study, the National Health and Nutrition Examination Survey, and the National Health Interview Survey. We find substantial declines over time in the magnitude of the association between obesity and overall mortality and, in certain instances, cardiovascular‐specific mortality. We conclude that estimates of the contribution of obesity to current national‐level mortality patterns should take into account recent reductions in the magnitude of the obesity and mortality association.
