Body fat distribution before pregnancy and gestational diabetes: findings from coronary artery risk development in young adults (CARDIA) study

Abstract
In 1985-6, the coronary artery risk development in young adults (CARDIA) study examined 5115 adults aged 18-30 years from four communities in the United States.2 Second, third, and fourth examinations were performed in 1987-8, 1990-1, and 1992-3. Prepregnancy risk factors assessed in 1985-6 included body mass index (in kg/m2), waist (minimal abdominal girth), and hip (maximal protrusion) circumferences. Fasting serum insulin concentration was measured by immunoassay.
