That fact that only a small percentage of women in Macau breast-feed induced the need to investigate this attitude. In collaboration with the Maternal & Child Health Division of the W.H.O., Geneva, it was decided that a methodology which had already been applied in other places should be used to investigate the relation between breast-feeding and fertility. In this way, information was obtained about the situation, within a given period of time which permitted a description of the duration of amenorrhea due to breast-feeding, as well as the patterns of frequency and duration of breast-feeding.
