A cluster randomised controlled trial of an early childhood parenting programme delivered through early childhood education centres in rural Zimbabwe.

BACKGROUND:Early childhood is a critical period for child development. Effective approaches to support families in low-resource settings in the use of responsive and stimulating parenting are needed. AIM:The aim of this study was to examine the effects of the Reach Up early childhood parenting programme on children's development, parenting attitudes and practices, when delivered through early childhood development (ECD) centres in Zimbabwe. METHODS:A cluster randomised controlled trial was conducted in Sanyati, a rural district in Zimbabwe. Twenty-four of 51 available centres were randomised to intervention (n = 12) or control (n = 12) groups. Sixteen mothers with a child aged 12-30 months were recruited from each centre's catchment area (n = 189 intervention; n = 193 control). The intervention comprised two home visits per month delivered by centre teaching assistants over a period of 27 months. Primary outcomes were child Developmental Quotient (DQ), Language, Eye and Hand coordination, Performance and Practical Reasoning subscale scores assessed at follow-up. Secondary outcomes were mothers' attitudes about child development, parenting practices and maternal depressive symptoms all measured at baseline and follow-up. Intention to treat analyses was conducted using mixed-effects regression models with the standard error adjusted for cluster and inverse proportionality weights to adjust for attrition. Significance was set at P < 0.05. RESULTS:A total of 285 (74.6%) of 382 children enrolled were tested, with 97 children lost to follow-up. The intervention improved the children's DQ by 3.55 points (95% CI 0.82 to 6.28), Eye and Hand by 3.58 (95% CI 0.59 to 6.56) and Practical Reasoning by 4.19 (95% CI 0.96 to 7.42). No significant improvements to Performance or Language scores, parenting attitudes, parenting practices and depressive symptoms were identified. CONCLUSIONS:A home visiting intervention delivered by ECD teaching assistants promoted children's development. This suggests that outreach from preschools may be an effective platform for delivery of parenting interventions.
