中年肥胖女性可能承受着比超重更多的负担。根据周日在华盛顿特区举行的美国老年学会年会上公布的研究结果,肥胖的经济代价很高:肥胖女性的净资产明显低于非肥胖的同龄人。这项新研究是最早关注肥胖对成熟人群而非年轻成年人影响的研究之一。

密歇根大学的社会科学家南希·H·富尔茨和她的同事分析了来自 7000 多名 50 多岁和 60 多岁男女的数据。虽然肥胖对男性的影响在统计学上不显着,但对女性的经济影响却相当大(参见右侧图表)。数据显示,1992 年,年龄在 51 岁至 61 岁之间的中度至重度肥胖女性的净资产比非肥胖女性低 40%。到 1998 年,差距扩大了。数据显示,年龄在 57 岁至 67 岁之间的肥胖女性的净资产比身材苗条的同龄人低 60%。即使在控制了健康、婚姻状况和其他人口因素后,这些差异仍然存在。“即使我们考虑了这些其他因素,肥胖对净资产的影响仍然存在,这与肥胖对女性来说在经济上是负担沉重的观点是一致的,”研究人员总结道。“这可能是由于文化上对吸引力的规范,以各种方式污名化肥胖女性。”
