Early Childhood Development Caregiver Training and Neurocognition of HIV-Exposed Ugandan Siblings.

OBJECTIVE

Early childhood development (ECD) programs can enhance neurocognitive development outcomes through caregiver training. This study explores whether school-age siblings benefited from a program provided to HIV-infected caregivers and their preschool-aged target children.

METHODS

Siblings of target 2- to 3-year-old children in ECD intervention households were evaluated at school age (5-12 years) on neurocognitive outcomes with the Kaufman Assessment Battery for Children (KABC), computerized Test of Variables of Attention, Behavior Rating Inventory for Executive Function (BRIEF; parent), and attention-deficit/hyperactivity disorder rating inventory (ADHD-R)-IV (parent). Households from 18 geographic clusters in eastern Uganda were randomized to individualized biweekly sessions of either (1) Mediational Intervention for Sensitizing Caregivers (MISC) training emphasizing cognitive stimulation/enrichment or (2) health/nutrition/development [Uganda Community-Based Association For Women & Children Welfare (UCOBAC)] program. Siblings with baseline and at least 1 follow-up assessment (n = 216) were included in the analysis. Three repeated postbaseline measures of sibling neurocognitive outcomes were analyzed using the linear mixed-effects model while adjusting for socioeconomic status and behavioral outcome at baseline.

RESULTS

Siblings in the MISC arm had better performance on KABC sequential processing at 6 months (p = 0.02) and simultaneous processing at 12 months (p = 0.03). MISC mothers rated their children as having significantly more problems on the BRIEF and ADHD-RS-IV (p < 0.01) than UCOBAC mothers across all time points.

CONCLUSION

Mediational Intervention for Sensitizing Caregivers training resulted in some short-term neurocognitive benefits for school-aged siblings, but these differences were not sustained at 1-year follow-up. Exploring potential impacts of parenting programs on other children in the home is an important development for the field.
