Structural equation model (SEM) with standardized path coefficients for the effect of Community Health Worker (CHW) contact on each of the three Maternal Knowledge categories and Childhood Iron Deficiency Anemia. Model is adjusted for household socio-economic status (SES), child’s age less than 24 months, gender, exclusive breastfeeding status and mother’s anemia status. Significant paths not shown: SES→Diarrhea Prevention (β = -0.093, SE = 0.033, p = 0.005); Child Age (<24 months) →Vitamin A and Iron Rich Foods (β = -0.071, SE = 0.035, p = 0.042); Child Age (<24 months) →Signs of Malnutrition (β = -0.097, SE = 0.034, p = 0.004); Mother’s Anemia→Signs of Malnutrition (β = -0.074, SE = 0.037, p = 0.043). Model fit: Number of free parameters = 75; ΔX ² = 11.653, Δdf = 4, p = 0.0201. RMSEA = 0.027, CI: 0.015, 0.038, p = 1.000; CFI = 0.969; TLI = 0.946; WRMR = 0.843; *p < .05; **p ≥ .001; ***p < .001
