Increase Breastfeeding Duration Among Puerto Rican Mothers

This study is to determine feasibility, acceptability, and preliminary effect sizes of
home-based individual breastfeeding consultation alone and combined with financial
incentives to increase breastfeeding (BF) duration among low-income Puerto Rican mothers.
These interventions will be tested in a Women, Infants, and Children (WIC) program, which
capitalizes on the current goals of WIC and on the current practice of using incentives to
support BF - factors that are likely to increase potential for sustainability and
dissemination of the intervention. We will follow a three phase strategy. During the
Formative Phase we will consult WIC staff, Puerto Rican postpartum mothers, and experts in
BF, behavioral health incentives, and WIC populations and settings to develop intervention
and research manuals. During the Implementation Phase, we will pilot the interventions and
research procedures. We will randomly assign 60 Puerto Rican women who initiate BF to:
Treatment-as-Usual (TAU) or TAU with financial incentives (also known as Contingency
Management; (CM). A bilingual breastfeeding counselor visits participants at home for
problem solving issues around breastfeeding. Participants also receiving CM will receive
cash incentives if they show breastfeeding. We will conduct assessments at baseline, 1, 3,
and 6 months postpartum, measuring BF duration, BF exclusivity, BF self-efficacy, and infant
weight gain. In the Evaluative Phase, we will examine monthly recruitment, consent, and
enrollment rates, as well as attendance and retention rates for the interventions and for
research participation (i.e., feasibility and acceptability).
