Energy supplementation in the last trimester of pregnancy in East Java, Indonesia: effect on maternal anthropometry

The effect of prenatal energy supplementation on maternal anthropometry was assessed in a controlled, randomized trial in Madura, East Java. At 26-28 wk of gestation women were either given 465 kcal/d (HE group) or 52 kcal/d (LE group). Two hundred seventy-six women were enrolled in the HE group and 266 women, in the LE group. Supplement intake was variable. Testing of effect by treatment and compliance was thus done by subcategories (HE 1-3 and LE 1-3, corresponding to less than 45, 45-89, and greater than or equal to 90 packets of supplement consumed). Analysis of variance did not show significant differences among the six subcategories in third-trimester weight gain, sum of skinfold thicknesses, 4-wk postpartum weight, or body mass index. In this population energy supplementation for the short duration of the last 90-110 d of pregnancy was not sufficient to improve maternal nutrition as judged by anthropometry.
