Participation in a 20-Year Randomized Dietary Trial and University Enrollment

Area of Science:

• Pediatrics
• Nutritional Science
• Public Health

Background:

• Childhood diet is critical for development and long-term health.
• The Special Turku Coronary Risk Factor Intervention Project (STRIP) involved a 20-year dietary intervention from 7 months of age.
• The intervention aimed to improve dietary fat quality and promote healthy foods to prevent cardiovascular diseases.

Purpose of the Study:

• To investigate the long-term effects of the STRIP dietary intervention on educational attainment.
• To examine the association between the intervention and university enrollment by age 26.
• To assess the intervention's impact on difficulties with school-related tasks at age 10.

Main Methods:

• A randomized controlled trial involving 1062 participants recruited in infancy.
• Participants were assigned to either a dietary intervention group or a control group.
• Linear probability models and ordinary least squares regressions were used to analyze university enrollment and school task difficulties.

Main Results:

• The dietary intervention was associated with a 32 percentage point increase in university enrollment among males from low-education families.
• A positive, though not statistically significant, association was observed for all males (11 percentage points).
• No significant association was found for females, and diet was suggested as a mediator rather than cardiovascular health.

Conclusions:

• Long-term dietary counseling is linked to enhanced educational attainment, particularly in males from socioeconomically disadvantaged backgrounds.
• The findings suggest potential indirect benefits of early-life dietary interventions on academic success.
• Further research may explore the specific mechanisms linking diet to educational outcomes.
