    Background: High-quality early childhood care and education (ECCE) programs can positively impact children's development. However, as an unintended consequence, ECCE attendance may also affect children's nutritional status. Objective: We evaluated the effect of a center-based ECCE intervention on child nutritional outcomes in rural Pakistan. Methods: This study utilized data from a stepped-wedge cluster randomized controlled trial of a center-based ECCE program that trained female youth to run high-quality preschools for children aged 3.5-5.5 years (LEAPS program) in rural Sindh, Pakistan. The program did not include any school meals. A total of 99 village clusters were randomized to receive the LEAPS intervention in three steps, and repeated cross-sectional surveys were conducted to assess the impact on children (4.5-5.5 years old) at four time points. Intention-to-treat analyses with multi-level mixed-effect models were used to estimate the effect of the intervention on child anthropometric outcomes. Results: The analysis included 3,858 children with anthropometric data from four cross-sectional survey rounds. The LEAPS intervention was found to have a positive effect on child HAZ (mean difference: 0.13 z-scores; 95% confidence interval (CI): 0.02, 0.24). However, there was a negative effect on weight-based anthropometric indicators, -0.29 WHZ (95% CI: -0.42, -0.15), -0.13 BMIZ (95% CI: -0.23, -0.03), and -0.16 MUACZ (95% CI: -0.25, -0.05). An exploratory analysis suggested that the magnitude of the negative effect of LEAPS on WHZ, BMIZ, and WAZ was greater in the survey round during the COVID-19 lockdown. Discussion: The LEAPS intervention positively affected child linear growth but had negative effects on multiple weight-based anthropometric measures. ECCE programs in low- and middle-income country settings should evaluate the integration of nutrition-specific interventions (e.g., school lunch, counseling on healthy diets) and infection control strategies to promote children's healthy growth and development.
