  1. Fulltext. Mortality and optimal body mass index in a sample of the US population.

    Article - En anglais

    Fulltext.

    In this paper, the authors model the nonmonotonic relation between body mass index (BMI) (weight (kg)/height2 (m2)) and mortality in 13,242 black and white participants in the NHANES I Epidemiologic Follow-up Study in order to estimate the BMI at which minimum mortality occurs.

    The BMI of minimum mortality was 27.1 for black men (95% confidence interval (Cl) 24.8-29.4), 26.8 for black women (95% Cl 24.7-28.9), 24.8 for white men (95% Cl 23.8-25.9), and 24.3 for white women (95% CI 23.3-25.4).

    Each confidence interval included the group average.

    Analyses conducted by smoking status and after exclusion of persons with baseline illness and persons who died during the first 4 years of follow-up led to virtually identical estimates.

    The authors determined the range of values over which risk of all-cause mortality would increase no more than 20% in comparison with the minimum.

    This interval was nine BMI units wide, and it included 70% of the population.

    These results were confirmed by parallel analyses using quantiles.

    The model used allowed the estimation of parameters in the BMI-mortality relation.

    The resulting empirical findings from each of four race/sex groups, which are representative of the US population, demonstrate a wide range of BMls consistent with minimum mortality and do not suggest that the optimal BMI is at the lower end of the distribution for any subgroup.
