Using logistic regression to describe the length of breastfeeding: a study in Guadalajara, Mexico

Effects of Support on the Initiation and Duration of Breastfeeding

Researchers attempted to increase the initiation of breastfeeding and its duration to 6 months among a group of low-income, Hispanic women through an intervention program which included prenatal education and home based postpartum support. All participants were telephoned after delivery to determine infant feeding method. Duration of breastfeeding was determined by counting the number of days from initiation to the last day the baby was put to the breast. The Bayesian approach was used for the statistical analyses. In the intervention group, the propensity to initiate breastfeeding exceeded that of the control group. Results indicate the intervention group had twice (2.31) the odds of starting breastfeeding, twice (1.84-3.15) the odds of continuing to breastfeed for 6 months, and only half (.50-.54) the tendency to quit at any one time than did the control group.

A new teaching model to prolong breastfeeding among Latinos

Latino women in Salt Lake City, Utah, have some of the lowest breastfeeding rates in the state. In an attempt to prolong breastfeeding duration in this population, the authors designed a new class to be taught by certified WIC (Special Supplemental Nutrition Program for Women, Infants, and Children) personnel to pregnant Spanish-speaking participants. The class was designed after a literature review and onsite ethnographic research. The term la cuarentena del bebé was introduced to signify the recommended 40 days when mothers should exclusively breastfeed, avoiding bottles, pacifiers, and supplementation. As part of the teaching model, class participants prepare an infant-feeding plan. Preliminary interviews show that WIC participants and staff view the new approach as an improvement. A randomized controlled trial is under way to evaluate the effectiveness of the class.
