Child development in rural Ghana: Associations between cognitive/language milestones and indicators of nutrition and stimulation of children under two years of age.

Objectives: Two studies aimed to assess the provision of nutrition and psychosocial stimulation in the home and to examine associations between mental development and nutrition and stimulation using a validated measure of development milestones.

Methods: The first study consisted of secondary analyses on health and nutrition data from 1081 mother-child pairs (the children aged 0-12 months) and their households in Ghana's Eastern Region. For the second study, the Ghana Milestones Measure, consisting of items assessing cognitive and language development, was used to assess child development in a subsample (N = 330) of Study 1 participants one year later (children 10-24 months of age). This measure was mother-reported and had been validated in a separate community in Ghana. Correlation and linear regression analyses were used to analyze the data.

Results: Family assets and maternal education were identified as key factors of the family context. Both variables were positively associated with preventive health practices (r = 0.08 to 0.13, p < 0.0001 to 0.01), and dietary diversity (r = 0.15, p = 0.0001 to 0.0006), and negatively associated with maternal depressive symptoms (r = -0.19 to -0.12, p < 0.0001). Taller children had higher receptive (standardized beta = 0.16; p = 0.04) and expressive (0.21; 0.003) language, but not cognitive (0.15; 0.07) milestone scores, and psychosocial stimulation was positively associated with all three milestones (receptive = 0.13, p = 0.01; expressive = 0.21, p < 0.0001; and cognitive = 0.24, p < 0.0001).

Conclusion: Our study provides the first validated measure of children's language and cognitive development in Ghana, finding associations with nutrition and stimulation. The Ghana Milestones Measure can be used to assess and help promote children's mental development.
