Effect of mid-day meal programme on physical growth & mental function.

D K Agarwal, K N Agarwal, S K Upadhyay

    The Indian Journal of Medical Research
    |June 1, 1989

    Summary

    Food supplementation in rural children improved nutritional status and cognitive functions, including IQ and arithmetic scores. Physical growth showed no significant catch-up, but weight gain was marginally better.

    Area of Science:

    • Nutrition Science
    • Developmental Psychology
    • Pediatrics

    Background:

    • Childhood malnutrition impacts physical growth and cognitive development.
    • Rural primary school children are particularly vulnerable to nutritional deficiencies.
    • Understanding the effects of food supplementation is crucial for improving child health and education outcomes.

    Purpose of the Study:

    • To evaluate the impact of food supplementation on physical growth and mental functions in rural primary school children.
    • To assess changes in nutritional status, intelligence quotient (IQ), and cognitive performance.
    • To determine the long-term effects of nutritional intervention on academic achievement and school attendance.

    Main Methods:

    • A two-year study (1984-1986) involving 146 rural primary school children.
    • Supplemented group received 450-500 calories and 10-12g protein daily.
    • Evaluated physical growth (height, weight), nutritional status (grade I/II), IQ, Piagetian tasks, Bender Gestalt test, and arithmetic achievement.

    Main Results:

    • No significant difference in height, but marginally better weight gain in the supplemented group.
    • Supplemented children maintained Grade I nutritional status, while controls shifted to Grade II.
    • Marginal improvements in full-scale, verbal, and performance IQ; significant improvement in most subtests except comprehension and maze.
    • Arithmetic achievement scores improved by 12-14 points; improved performance on Piagetian conservation of liquid task.
    • No change observed on the Bender Gestalt test.

    Conclusions:

    • Nutrition supplementation is beneficial for improving school attendance and reducing dropout rates.
    • Supplementation offers marginal benefits to intelligence and cognitive functions in this age group.
    • No significant catch-up in physical growth was observed, likely due to the slow growth period during childhood.
