A cross»sectional study was conducted to determine the knowledge on family planning among Malay women who delivered at Hospital Universiti Sains Malaysia (H USM), Kelantan and their husbands. Three hundred and fifty five women were selected by systematic random sampling. An interview-guided questionnaire that included infomation on socio-demographic, obstetric and knowledge on family planning was conducted to the women and self-administered questionnaire was given to their husbands. There were 15 questions on knowledge which were validated prior to the study. More than half of the women (53.5%) and the husbands (57.7%) had poor knowledge score (less than 75%) on family planning. A majority (86.8%) of the women and 87.9% of the husbands knew the optimal age of a woman to be pregnant, but very few (3.4%) of the women and Ss 1% of the husbands could answer correctly all the questions on the effects of poor spacing. The level of knowledge on family planning among Malay women who delivered at H USM and their husbands were poor. Therefore, new and improved health education materiab and programmes are needed, to target both the women and their husbands.
