Using a breastfeeding prevalence survey to identify a population for targeted programs

Often, efforts to improve overall population health require identifying and targeting programs to specific high-risk populations. Breastfeeding is an example. In order to determine initiation and duration rates among various groups in the City of Toronto, a random sample of 434 mothers with infants at four months of age was surveyed to determine the prevalence of breastfeeding and major impacts on its duration. The study found that, overall, 83% of mothers initiated breastfeeding at birth. The greatest rate of decline occurred during the first month. At four months postpartum, 57% of mothers continued to breastfeed, including 35% who were exclusively breastfeeding and 22% who were supplementing breast milk with formula. Breastfeeding duration was related to a number of factors, including information and support, parity, education, use of formula supplements and country of birth, Specific groups are identified for targeted programs, and a number of strategies are proposed.
