This study was conducted among working mothers in three factory sites at the Mactan Export Processing Zone in Mactan Island, Cebu to determine if promoting breastfeeding in an Integrated Health Approach (IHA) would increase the ability of the working woman to achieve sustained and successful breastfeeding and determine its potential economic impact. The working mothers of two factories were exposed to a breastfeeding education program on the benefits of the sustenance of breastfeeding from the third trimester of pregnancy, while the pregnant women in the other factory served as the control group. A total of 73 pregnant working women qualified and was entered into the study; with 39 women in the IHA exposed group and 34 women to the non-IHA exposed group. A significantly greater proportion of babies in the exposed group were purely breastfed at birth compared to the unexposed group and IHA was associated with more than four-fold rate of continuing pure breastfeeding during the first three months. Economic needs appear to play the largest role in the mother's decision as to the choice of breastfeeding besides other influences as location of the work place and the presence of the hired help or relatives who can assume the care of the child in the mother's absence.
