Impact of the "Ten Steps for Healthy Feeding of Children Younger Than Two Years" in Health Centers

Cluster randomized controlled trial targeting selected primary health care centers in Porto Alegre, South of Brazil, a city of 1.4 million inhabitants. The trial included health centers that provide primary care services predominantly to low-income families.Physicians, nurses and administrative staff of all intervention health centers participated in a training in January 2008 based on the "Ten Steps for Healthy Feeding for Brazilian Children from Birth to Two Years of Age" guideline.

Following staff training at the intervention sites, interviewers visited the intervention and control health centers from April to December 2008 to identify and enroll pregnant women who were in the last trimester of pregnancy. 98% of eligible pregnant women agreed to participate and answered a questionnaire about their socioeconomic status and expected due date. Addresses and telephone numbers were obtained in order to schedule subsequent home visits.

Data Collection:

Maternal interviews using structured questionnaires were conducted at baseline (during pregnancy - 2008) and at follow-up home-visits at mean child ages six months (2008/2009), 12 months (2009/2010) , three years (2011/2012) and six years (2014/2015) by field workers who were not involved in the intervention and who were unaware of the group allocations.
