To describe the contribution to dietary intake of Prospera supplements in children and the association with socioeconomic status (SES).
We obtained sociodemographic and dietary intake information from 398 children (< 3y old) beneficiaries of Prospera in San Luis Potosi, Mexico. Socioeconomic status was developed classifying households considering variables like head of household schooling, flooring, ownership of home appliances, number of rooms and number of rooms with bathroom. We estimated the percentage contribution of Prospera distributed supplements to total dietary intake (PCDI) of energy, protein, zinc, iron, vitamin C, vitamin A, folate and vitamin B12 through a semi-quantitative food frequency questionnaire. We assessed the association of PCDI and socioeconomic status with zero-inflated negative binomial regression models adjusted by sex and age, interaction between SES and sex was tested
Significant interaction between socioeconomic status and sex was found for energy and protein intakes. Girls of low socioeconomic status showed higher PCDI than boys (energy and protein p= 0.054 and 0.045; respectively). Children of low socioeconomic status had higher PCDI of vitamins and minerals analyzed than children of high socioeconomic status.
The PCDI of supplements is higher in children of low socioeconomic status who are the primary target of Prospera Program. It is necessary to study dietary quality in Prospera beneficiaries and assess the program coverage.
