In a large set of measurements on nonpregnant women, the average fasting blood glucose level was about 80 milligrams/100 milliliters of blood. Research- ers determined fasting blood sugar levels for 52 women during their third trimester of pregnancy (contributed by C. M. Mahan to a collection of prob- lems in Andrews and Herzberg, 1985, pages 211-214; from O'Sullivan and Mahan, 1966).
