Insights
In a South African low-income community, 73% of young children showed possible developmental delays. Exposure to multiple languages and older age were significant risk factors for developmental delays in children.
Area of Science:
- Child Development
- Public Health
- Socioeconomic Factors
Background:
- Early childhood development is crucial for long-term outcomes.
- Low-income communities often face unique challenges impacting child development.
- Understanding developmental risks is vital for timely intervention.
Purpose of the Study:
- To identify developmental risks in young children from a low-income South African community.
- To examine the influence of these risks on child development outcomes.
Main Methods:
- An exploratory, cross-sectional study design was used.
- 126 children (0-42 months) and their caregivers participated in home visits.
- Developmental screening and binomial logistic regression were employed.
Main Results:
- 73% of children screened positive for possible developmental delay based on caregiver reports.
- Exposure to multiple languages significantly increased the risk of developmental delay (OR 3.810).
- Older children (19-42 months) were at higher risk than younger children (0-18 months).
Conclusions:
- Healthcare professionals should educate caregivers on developmental risks, especially multiple language exposure.
- Early identification and intervention are critical for vulnerable populations.
- Addressing socioeconomic factors can improve developmental trajectories.
Objective:
To describe the developmental risks, and its influence, in young children from a low-income South African community.
Method:
An exploratory, cross-sectional research study design was employed. Developmental screening was conducted during home visits with 126 caregivers and children between 0 and 42 months of age from a low-income South African community. Children who failed the rescreen were referred for diagnostic assessment. A binomial logistic regression was used to determine the effect of developmental risks on developmental outcomes.
Results:
Seventy-three percent of children screened were identified with a possible developmental delay (n = 59) according to caregiver-report using the PEDS tools. The regression model was statistically significant (χ2 (3) = 34.902, p < 0.001) with exposure to multiple languages (p < 0.05; odds ratio 3.810, CI 1.2-12.4) most indicative of potential developmental delay. Older children (19-42 months) were also more at risk of developmental delay (p < 0.001) than younger children (0-18 months).
Conclusions For Practice:
Healthcare professionals serving these vulnerable populations should create awareness amongst caregivers about the effect of developmental risks, in particularly multiple language exposure, on development.
