BMI: a poor surrogate for diet and exercise in assessing risk of death.

In acknowledging the limitations of the Flegal analysis, the authors admit that 'other factors associated with body weight, such as physical activity, body composition, visceral adiposity, physical fitness, or dietary intake, might be responsible for some or all of the apparent associations of weight with mortality'.1 Flegal was not able to prove that the association of BMI with mortality remained after appropriate adjustments for potentially confounding factors, particularly physical activity, physical fitness, dietary intake, age, and sex. Indeed, previous epidemiological studies found that significant correlations of BMI with mortality disappeared after adjusting for other confounding factors. The recently published long-term data from the Framingham Heart Study showing that 9 out 10 men and 7 out of 10 women will eventually become overweight or obese8 raises the question of whether Flegal adequately adjusted for age and sex.
