Study Start Date: September 1987

Detailed Description:


In 1987, there was growing evidence that androgens, particularly when elevated, had an unfavorable effect on lipo/apo levels, tending to lower HDL cholesterol (HDLC) and raise LDL cholesterol (LDLC). Previous studies confirmed that although pre-pubertal boys and girls had similar lipo/apo levels, post-pubertal boys had a higher ratio of LDLC/HDLC than girls, in part because of their androgen levels. Such lipo/apo levels had been associated with an increased risk of coronary heart disease. There was also evidence that obese girls tended to be hyperandrogenic and thus had unfavorable lipo/apo levels and a higher risk of coronary heart disease. This study sought to elucidate whether high androgen levels preceded or were a consequence of obesity.


The longitudinal study was ancillary to the National Growth and Health Study (NGHS), a multicenter study which investigated the occurrence of obesity in Black and white adolescent girls, predictors of the transition to the obese state, the correlates of the transition, and the relationship of the transition to other coronary heart disease risk factors. As part of the NGHS, participants from the Cincinnati, Ohio and Washington, D.C. public and parochial schools received physical examinations with attention to pubertal staging and anthropometric measurements including weight, height, and skinfold thickness. Along with NGHS blood samples, additional blood was obtained in years 1, 3, and 5 for measurements of lipids, lipoprotein cholesterols, apolipoproteins A1, A2, and B, and sex steroid hormones including plasma total and free testosterone, dehydroepiandrosterone sulfate, estradiol, and testosterone estrogen binding globulin.
