Percentage body fat ranges associated with XXXX risk: results based on the third National Health and Nutrition Examination Survey (1988-1994).

@entity209 @entity1 @entity1386
BACKGROUND: Increasing attention has focused on the association between body @entity1386 and related metabolic risk factors. The quantitative link between percentage body fat (%BF) and the risk of @entity209 is unknown. OBJECTIVES: The objectives were to determine the risk [odds ratios (ORs)] of @entity209 based on %BF in black and white @entity1 and @entity1 in the United States and to provide corresponding ranges of %BF associated with a risk equivalent to body mass index (BMI; in kg/m(2)). DESIGN: The subjects were @entity1 in the third National Health and Nutrition Examination Survey and were divided into those with and without the @entity209 . OR equations were derived from logistic regression models for %BF and BMI, with the 25th percentile in the study population as the reference. Ranges were developed by associating %BF with the equivalent risk of @entity209 based on established BMI cutoffs. RESULTS: Four sets ( @entity1 , @entity1 , black, and white) of OR curves were generated for %BF and for BMI by using data from 8259 adults. The ORs for @entity209 were lower in blacks than in whites at any given %BF or BMI. The developed cutoffs for %BF differed between @entity1 and @entity1 but showed only small race and age effects. A simplified set of sex-specific %BF ranges for the risk of @entity209 were developed. CONCLUSIONS: The risk of @entity209 can be established from measured %BF by using either the developed OR curves or %BF thresholds at traditional BMI cutoffs. This information should prove useful in both clinical and research settings.
