Due to the Covid-19 contingency, activities were suspended in March 2020. Baseline measurements were obtained for n=764 children whose caregivers enrolled in the NPECDP-UKA.

Investing in early childhood development is one of the best cost-effective investments a country can make to boost long term economic growth, promote peaceful and sustainable societies, contribute to tackle poverty traps and eradicate inequality. It is also necessary to uphold the right of every child to survive and thrive. The single most powerful context for nurturing care is the immediate home, often mainly provided by mothers.

Although the Mexican government has implemented social programs in the past, some with nutrition and child development components, poor and isolated communities have not benefited as others easier to reach. This is particularly true for the State of Oaxaca given its orography, where higher levels of malnutrition and a higher risk of suboptimal neurodevelopment are present.

Since 1989, Un Kilo de Ayuda A.C. (UKA), a nongovernmental organization, has been involved in preventing child undernutrition in contexts of high poverty. Currently, UKA has 9 Early Childhood Development Centers distributed in 5 States of Mexico, including Oaxaca. UKA has developed the Neurological and Psycho-affective Early Childhood Development Program (NPECDP-UKA) that seeks to contribute to timely stimulation in children under 5 years of age and promote perceptual parenting practices. As part of the NPECDP-UKA, UKA redesigned their interventions to promote healthy nurturing care practices and responsive caregiving through workshops provided to caregivers and pregnant women, and with reinforcement through home visits.

It is in the interest of this study to evaluate the NPECDP-UKA through a variation of a stepped wedge cluster randomized trial. The study sample consists of participants from 80 municipalities of Oaxaca (~50% with high or very high margination status), 20 municipalities were randomly assigned to each arm. Study arms differ by design on the time of exposure to the program (0,18,24 and 30 months at the final measurement). Subjects from all study groups share the characteristic to be enrolled in the NPECDP-UKA, the group with 0 months of exposure will serve as a comparison group. This distinctive characteristic of the study requires a progressive incorporation of study groups to be able to compare development measurements between study groups at the same ages and among subjects all enrolled in the program to avoid self-selection bias. The main study hypothesis states that children exposed to the Program will have better neurodevelopment outcomes than those not exposed.

This study will provide evidence of the effect of an educational intervention for caregivers on the neurodevelopment of children under 5 years of age. Currently evidence of such interventions is very limited, especially for interventions performed by a nongovernmental organization. This is the first evaluation of this kind in Mexico.
