Effect of khat on maternal food intake, maternal weight gain and fetal growth in the late-pregnant guinea pig

Abstract

Khat chewing is a widespread male social habit in countries around the southern shore of the Red Sea and in eastern Africa and is also practiced by women, even during pregnancy and lactation. In order to study the potentially adverse effects of khat chewing during pregnancy, guinea pigs were fed 2.2 g kg of khat leaves daily throughout the third trimester. Control animals were given aspen leaves. Maternal daily food intake was significantly reduced during the first 10 days of feeding and maternal weight gain was slightly lower in the khat group. Khat feeding of the mother significantly reduced the mean birth weight of the offspring by 7% without any effect on litter size or length of gestational period. Since low birth weight is a well-established risk factor for both perinatal and young infant death, khat chewing during pregnancy may be one of the factors contributing to infant mortality.
