Abstract
OBJECTIVE To examine the diabetes risk association with femur length, standing height, and height without femur length (HWFL) (HWFL = standing height − femur length).
RESEARCH DESIGN AND METHODS We used data from three time periods of the National Health and Nutrition Examination Survey (1999–2000, 2001–2002, and 2003–2004) for this cross-sectional analysis and confined the eligible subjects to 6,188 adults aged 20+ years who had fasted ≥8 h and had no missing values of femur length or standing height. The outcome measure was type 2 diabetes.
RESULTS Multivariate logistic regression analyses indicated that the odds of type 2 diabetes per 1-SD value increase in femur length, standing height, and HWFL were 0.73 (95% CI 0.61–0.86), 0.91 (0.75–1.10), and 1.09 (0.90–1.32) for men, respectively, and 0.82 (0.70–0.97), 0.99 (0.82–1.21), and 1.11 (0.93–1.33) for women.
CONCLUSIONS Our study supports the hypothesis that femur length may be the key height component in diabetes risk association.
