A prospective study was undertaken of 189 indigent black and white women receiving prenatal care at a clinic. The various activities in which these women were involved were carefully measured including occupational, recreational and household activities. About 40% of the women had worked outside the home during pregnancy. Average weekly kilocalorie expenditure levels for each of the three types of activity were calculated each trimester. Increased total weekly physical activity levels were associated with decreased birth weight among black women, but not among white women. A difference in activity patterns of housekeeping existed between blacks and whites and it was this activity which was related to decreased birth weight among the blacks. This effect persisted after controlling for maternal height, smoking habits, prepregnant weight, and gestational weight gain. Predictors of decreased birth weight among whites included smoking, prepregnant weight and gestational weight gain.
