Preschool development of coloured children in Cape Town

Area of Science:

• Child Development
• Pediatrics
• Public Health

Background:

• Developmental screening is a common practice in infancy to identify potential developmental delays or disabilities.
• Early identification of developmental issues is crucial for timely intervention and improved child outcomes.
• The effectiveness and limitations of developmental screening tools require ongoing evaluation.

Purpose of the Study:

• To evaluate the utility of developmental screening in a cohort of infants in Cape Town.
• To assess the correlation between developmental progress and various socio-economic factors over a 5-year period.

Main Methods:

• A birth cohort of 1,000 infants in Cape Town was established.
• Developmental screening was applied during infancy.
• A randomly selected sample of 187 children was followed for 5 years to track developmental progress.

Main Results:

• Developmental screening identified limitations, with some major handicaps diagnosed prior to screening and one case of deafness missed.
• Developmental milestones were comparable to existing literature.
• At 12 months, development correlated with family stability.
• At 30 months, language development was linked to maternal education and family stability, indicating a general verbal skills lag.
• By 5 years, development showed a strong correlation with social indicators, including income and mother's education.

Conclusions:

• The study questions the overall value of routine developmental screening in this context due to missed diagnoses.
• Socio-economic factors, particularly maternal education and family stability, play a significant role in child development outcomes.
• Longitudinal assessment highlights the importance of social determinants in predicting developmental trajectories.
