A project which attempted to answer the question whether pregnant women from the inner city would attend prenatal classes is discussed. Specific purposes of the project were: (1) to find a way to obtain and retain attendance at prenatal classes of expectant mothers who live in low socioeconomic urban areas, (2) to identify factors affecting their attendance at the classes, and (3) to provide comparative data on the expectant mothers who attended the classes and on others from the same area who knew about the classes but did not attend. A series of prenatal classes was developed, consisting of seven classes to be held at weekly intervals. Each class lasted approximately one and a half hours. Interviews were conducted with all expectant mothers who attended the classes to obtain health and socioeconomic information. Findings of the project include: (1) Expectant mothers who live in lower socioeconomic urban areas will attend prenatal classes; (2) The most desirable site for the classes proved to be a hospital located near the mothers' homes, and the best time to hold meetings was in the evening; and (3) Health practices of expectant mothers who attended the classes were better than those of expectant mothers who did not attend.
