Individuals with non-insulin-dependent diabetes mellitus (NIDDM) have a higher body mass index (BMI) than nondiabetic individuals and it has been reported that individuals with NIDDM have more difficulty losing excess weight. To assess an independent effect of NIDDM on weight status, analyses were conducted to predict BMI with variables previously associated with weight status. Subjects from the Second National Health and Nutrition Examination Survey were categorized into three groups: individuals with NIDDM and on oral medication, individuals with diet-controlled NIDDM, and nondiabetic adults. Additionally, planned orthogonal comparisons between these groups were conducted after other predictors were controlled for; 9.18% of the variability was explained for men (P less than 0.001) whereas 12.11% was explained for women (P less than 0.0001), with several variables significantly related in each model. An independent effect for diabetes status was found in both sexes and there were no differences in BMI between NIDDM groups in either sex.
