Overview

Cohort study finds low weight increases mortality risk more than obesity in older adults, indicating standard overweight definitions may be inappropriate for seniors.

Key Points

To determine whether body weight and body mass index serve as independent risk factors for mortality among older adults.
Analyzed body mass index (BMI) data from N=4,710 white respondents aged 55 to 74 years from the National Health and Nutrition Examination Survey (1971–1975).
Evaluated survival over an average follow-up of 8.7 years using multivariate analysis controlling for elevated blood pressure, smoking status, and poverty.
High BMI (≥ 30 kg/m²) conferred no additional mortality risk in women and a moderate risk in men in the upper decile (relative risk, 1.1 to 1.2).
Low BMI (< 22 kg/m²) was associated with increased mortality (relative risk, 1.3 to 1.6) across all groups except women aged 55 to 64 years.
