Insights
An intensive early intervention for low birth weight infants did not significantly alter special education or therapy use by age 8. Many children with learning disabilities had unmet needs for school-based support services.
Area of Science:
- Developmental Pediatrics
- Educational Psychology
- Public Health
Background:
- Low birth weight infants are at increased risk for developmental delays and learning disabilities.
- Early intervention programs aim to mitigate long-term effects of prematurity and low birth weight.
- The Infant Health and Development Program (IHDP) provided intensive early intervention services.
Purpose of the Study:
- To evaluate the long-term impact of the IHDP on special service utilization in school-aged children.
- To determine if early intervention affects the need for special education, remedial services, or speech therapy at age 8.
- To assess service use among children with learning disabilities (LDs) in relation to the intervention.
Main Methods:
- Randomized controlled trial (RCT) of the IHDP for low birth weight infants (0-3 years).
- Multivariate logistic regression used to analyze intervention effects on special service use at age 8.
- Comparison of service utilization rates between intervention and control groups, particularly for those with LDs.
Main Results:
- No statistically significant differences were found between intervention and control groups for special education, remedial reading, remedial math, or speech therapy.
- Rates of learning disabilities (LDs) did not differ between the study arms.
- Service utilization for children with LDs was low and not influenced by the early intervention.
Conclusions:
- Early IQ gains from infant interventions may not translate into protection against educational challenges in grade school.
- A significant unmet need for school-based support services exists among low birth weight children with learning disabilities.
- The findings highlight the importance of continued support and identification of needs beyond early intervention for at-risk children.
Objectives:
To evaluate the effect of an intensive early intervention on special service use at school-age.
Study Design:
The Infant Health and Development Program was a randomized controlled trial of an intervention for low birth weight (<2500 g) infants ages 0-3 years. We used multivariate logistic regression to test the association between intervention and risk of special education, remedial reading and math, and speech therapy at age 8 years. We also compared rates of service use between study arms among those with learning disabilities (LDs).
Results:
There were 875 complete cases at 8-year follow-up. There were no statistically significant differences between groups in risk of special education (risk ratio [RR] 0.86, 95% CI 0.64-1.15), remedial reading (RR 0.88, 95% CI 0.68-1.14), remedial math (RR 0.92, 95% CI 0.63-1.34), or speech therapy (RR 0.87, 95% CI 0.62-1.23). The treatment arms did not differ in rates of LDs, and service use for those with LDs was low and unaffected by study group.
Conclusions:
Early gains in IQ from infant interventions may not protect children as they face the educational demands of grade school. Only a fraction of those having a LD were receiving school-based support services, indicating a high level of unmet need among low birth weight children with disabilities.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
