Scalable interventions are needed to improve infant and young child feeding (IYCF). We evaluated whether an IYCF nutrition communication strategy using radio and nurses changed beliefs, attitudes, social norms, intentions, and behaviors related to breastfeeding (BF), dietary diversity, and food consistency. Women with children 6-24 mo were randomly selected from 6 semi-urban, low-income communities in the Mexican state of Morelos (intervention, n = 266) and from 3 comparable communities in Puebla (control, n = 201). Nurses delivered only once 5 scripted messages: BF, food consistency, flesh-food and vegetable consumption, and feed again if food was rejected; these same messages aired 7 times each day on 3 radio stations for 21 d. The control communities were not exposed to scripted messages via nurse and radio. We used a pre-/post-test design to evaluate changes in beliefs, attitudes, norms, and intentions as well as change in behavior with 7-d food frequency questions. Mixed models were used to examine intervention-control differences in pre-/post changes. Coverage was 87% for the nurse component and 34% for radio. Beliefs, attitudes, and intention, but not social norms, about IYCF significantly improved in the intervention communities compared with control. Significant pre-/post changes in the intervention communities compared with control were reported for BE frequency (3.7 +/- 0.6 times/d), and consumption of vegetables (0.6 +/- 0.2 d) and beef (0.2 +/- 0.1 d) and thicker consistency of chicken (0.6 +/- 0.2 d) and vegetable broths (0.8 +/- 0.4 d). This study provides evidence that a targeted communication strategy using a scalable model significantly improves IYCF.
