Abstract
The influence of rest versus hard work on fetal growth at the end of pregnancy was assessed prospectivley in a population of women who normally work hard during pregnancy. A group of 554 women living Kalima area (Central Zaire) was admitted for rest in a maternity village for a median duration of 22 days. Self-selection, age, parity, number of living children, socio-economic status, maternal weight and height and gestational age were controlled for. Energy intake estimated in a sample of women in the maternity village and a sample of this staying at home was similar. Protein intake was found to be higher in the resting women. The duration of rest had a strong influence on birthweight and length in the newborn females but to a lesser extent in the newborn males. There was a 7.5-fold decrease in the rate of low birthweight in girls when the duration of maternal rest was > 21 days. In boys the low-birthweight rate remained unchanged. Although this sex difference could not be explained it is concluded that, in developing countries, avoidance of heavy work can help to raise birthweight and perhaps reduce perinatal mortality.This publication has 20 references indexed in Scilit:
