The Community Nutrition Program in El Alto, Bolivia is the second phase of a program originally implemented between 2008 and 2011. The newly-structured program had objectives to improve infant and young child feeding practices, hygiene, and child nutritional status through a behavioral-change strategy based on participatory play education. This dataset includes the data of an evaluation survey to this program, which contains three rounds of data—Baseline (2014), endline 1 (2016) and endline 2 (2017)—on an (unbalanced) panel of 2015 households with children under the age of 12 months or pregnant women at baseline. The survey includes a rich set of socio-economic, demographic and nutrition variables. Datasets were anonymized to protect subject privacy. Variable names, their labels, and any actions taken for de-identification purposes are noted in the codebook below.
