Study links preschool conceptual skills with growth, stimulation and social status in Nepal

Researchers conducted a cross-sectional analytical study of 401 children aged 3–5 years attending Early Childhood Development centers in Rupandehi District, Nepal. They assessed conceptual skills using a standardized component of a cognitive development tool and collected information on children’s anthropometry, family and socioeconomic characteristics, psychosocial stimulation, and caregivers’ nutritional practices. Multiple linear regression was used to examine associations.

Higher height-for-age z-scores, greater psychosocial stimulation and relatively advantaged caste/ethnic group status were associated with higher conceptual skill scores. Cesarean delivery and increasing child age were associated with lower scores. Results for nutritional edema and household economic ranking were unstable across model specifications and were not interpreted as independent effects. The final model explained 35.3% of score variance (adjusted R²=0.353; p<0.001).

The findings point to associations between early childhood conceptual skills and nutritional, psychosocial and social factors in this district. Because the study was cross-sectional, it cannot establish that these factors caused differences in scores. The results may also have limited applicability beyond the sampled setting; they do not by themselves demonstrate the effect of any specific intervention.
