Cause-Specific Excess Deaths Associated With Underweight, Overweight, and Obesity

Abstract

In a previous study,¹ we estimated excess all-cause mortality associated with underweight, overweight, and obesity in the United States in 2000 using data from national surveys. We found significantly increased all-cause mortality in the underweight and obese categories and significantly decreased all-cause mortality in the overweight category compared with normal weight. To gain further insight into these findings, we now extend that work, using additional mortality data with longer follow-up, to examine the association of cause-specific mortality with different weight categories among US adults in 2004.
