Tenfelde S, et al. Predictors of breastfeeding exclusivity in a WIC sample. J Obstet Gynecol Neonatal Nurs. Mar 2011;40(2):179-189.
This study examined predictors of breastfeeding exclusivity in low-income women who received services from a Chicago-area WIC clinic. Researchers found that women who received first-trimester prenatal care were more likely to exclusively breastfeed than were women who entered prenatal care in later trimesters. In addition, women who declared intentions prenatally to exclusively breastfeed were more likely to exclusively breastfeed than were women who did not intend to breastfeed. Furthermore, overweight/obese women were less likely to exclusively breastfeed than were normal/underweight women.
