Emotional changes in pregnancy and early puerperium among the Yoruba women of Nigeria.

A randomly selected clinic population of 400 pregnant women in Ile-Ife, Nigeria, were interviewed for complaints of psychological disorders during the last trimester of pregnancy and the post-partum period. The study shows a considerable degree of psychological disturbances during pregnancy which later decreased significantly during the post-partum. While the complaints of worrying, guilt-feeling, nausea and vomiting and "heat in-the-head", were significantly more common in younger women, insomnia and anorexia were more common in older women. The incidence of psychological complaints among the women decreased with increasing parity. There was no significant difference in the incidence between women with monogamous and polygamous marriages.
