Abstract
OBJECTIVES: The objective of the study was to demonstrate the influence of several socioeconomic factors on the motor and language development of children under 5 from the baseline study conducted within the framework of the Joint Program for Children, Food Security, and Nutrition, implemented by five United Nations agencies across 65 districts in the departments of Loreto, Ayacucho, Huancavelica, and Apurímac, Peru. METHODS: Dichotomous logistic regression models were used to estimate the likelihood of achievement of motor and language milestones, while polynomial regression models were used to estimate the last milestone achieved and the number of milestones achieved. The study analyzes the influence that maternal education, urban vs. rural housing, and unmet basic needs have on the difference between actual results and expected results for age was analyzed. RESULTS: Children living in rural areas, those whose mothers had low educational attainment, and those from households with unmet basic needs exhibited poorer outcomes in the two areas of development assessed. As the number of risk factors increased, so did the developmental delay. CONCLUSIONS: Evaluation of child development and follow-up of families during the child-rearing process should be prioritized by health systems and social programs. The instruments used were sensitive to three criteria for validation.
