THE IMPACT OF PROPER NUTRITION HYGIENE ON HEALTHY GROWTH AND INTELLECTUAL DEVELOPMENT IN SCHOOL-AGED CHILDREN

Abstract

Background: School age (7–17 years) is a critical period for physical growth and cognitive maturation. In Uzbekistan, rapid dietary transitions and the double burden of malnutrition (undernutrition and obesity) pose significant challenges. This study aims to evaluate the correlation between adherence to nutritional hygiene rules, physical development indices, and academic performance among schoolchildren in the Andijan region. Methods: A cross-sectional analytical study involved 500 schoolchildren aged 10–14 years. Nutritional habits were assessed using a validated Food Frequency Questionnaire (FFQ) and hygiene behavior surveys. Anthropometric measurements (BMI-for-age) were taken to assess physical status. Intellectual development was measured using academic grades and the Raven’s Progressive Matrices test. Results: Children with irregular meal patterns and low hygiene compliance showed a significantly higher prevalence of stunting (12.4% vs 4.2%) and anemia (28% vs 10%) compared to the compliant group (p<0.001). There was a strong positive correlation (r=0.68) between a balanced diet rich in micronutrients (iron, iodine) and cognitive performance scores. Conversely, excessive consumption of processed foods was linked to attention deficits and lower academic achievement. Conclusion: Adherence to nutrition hygiene principles is a fundamental determinant of both somatic health and intellectual potential. Implementing school-based nutritional education programs is essential for fostering a healthy future generation.
