Weight loss from maximum body weight and mortality: the Third National Health and Nutrition Examination Survey Linked Mortality File



The aim of this longitudinal study is to examine the relationship between weight loss from maximum body weight, body mass index (BMI), and mortality in a nationally representative sample of men and women.


Longitudinal cohort study.


In all, 6117 whites, blacks, and Mexican-Americans 50 years and over at baseline who survived at least 3 years of follow-up, from the Third National Health and Nutrition Examination Survey Linked Mortality Files (1988–1994 with passive mortality follow-up through 2000), were included.


Measured body weight and self-reported maximum body weight obtained at baseline. Weight loss (maximum body weight minus baseline weight) was categorized as <5%, 5–<15%, and 15%. Maximum BMI (reported maximum weight (kg)/measured baseline height (m)2) was categorized as healthy weight (18.5–24.9), overweight (25.0–29.9), and obese (30.0).


In all, 1602 deaths were identified. After adjusting for age, race, smoking, health status, and preexisting illness, overweight men with weight loss of 15% or more, overweight women with weight loss of 5–<15%, and women in all BMI categories with weight loss of 15% or more were at increased risk of death from all causes compared with those in the same BMI category who lost <5%; hazard ratios ranged from 1.46 to 2.70. Weight loss of 5–<15% reduced risk of death from cardiovascular diseases among obese men.


Weight loss of 15% or more from maximum body weight is associated with increased risk of death from all causes among overweight men and among women regardless of maximum BMI.
