The health consequences of obesity and overweight have been well documented, but less research has examined their social and economic consequences. This paper examines the long-term consequences of early adult overweight for midlife health and socioeconomic attainment using prospective nationally representative panel data from American adults in the Monitoring the Future Study (1986-2008). Growth mixture models identified 2 distinct latent classes of trajectories of body mass index (BMI) from age 19 to 35 years : a persistently overweight class (BMI>25 kg/m2) and a second class exhibiting more moderate growth in BMI to age 35 years. Women (odds ratio (OR)=2.16,95% confidence interval (CI) : 1.39,3.36) and those from a lower childhood socioeconomic position (OR=1.71,95% CI : 1.30,2.24) were more likely to be in the persistently overweight class. Compared with those in the moderately increasing BMI class, those in the persistently overweight class were more likely to have a chronic health problem at age 40 years (OR=2.74,95% CI : 2.20,3.43), to have no further education beyond high school (OR=1.33,95% CI : 1.04,1.69), and to have a higher odds of receiving welfare or unemployment compensation at age 40 years (OR=1.76,95% CI : 1.49,2.04). These findings highlight the importance of addressing persistent obesity and overweight early in the life course.
