Normative data on mental and motor development in Nigerian children

Area of Science:

• Pediatrics
• Developmental Psychology
• Child Health

Background:

• Sub-Saharan Africa, including Nigeria, has historically relied on Caucasian data for child developmental assessments.
• This reliance may not accurately reflect the psychomotor development of local populations.

Purpose of the Study:

• To establish normative data for psychomotor development specific to Nigerian children.
• To address the gap created by the over-reliance on non-local developmental data.

Main Methods:

• A cross-sectional study included 128 children across eight age groups (8-30 months).
• Developmental Screening Inventory (DSI) and Bayley Scales of Infant Development (BSID) were used for assessment.
• Data collection involved trained research assistants and blind scoring to minimize bias.

Main Results:

• Nigerian children scored above established normal values across five developmental fields.
• Higher scores were observed in motor and personal-social domains, particularly in younger age groups (8, 16, 32 weeks).
• Findings indicate a divergence from Western developmental data.

Conclusions:

• The derived normative data holds significant clinical value for Nigerian healthcare practitioners.
• This data will aid pediatricians, psychiatrists, and clinical psychologists in accurate child development assessments.
• Establishing local developmental benchmarks is essential for effective pediatric care in Nigeria.
