Factors Affecting Underweight and Obesity Among Elementary School Children in South Korea

Area of Science:

• Pediatric Nutrition
• Public Health
• Childhood Obesity Research

Background:

• Childhood underweight and obesity are significant public health concerns globally.
• Prevalence varies across different regions and socioeconomic groups.
• Understanding associated factors is crucial for developing effective interventions.

Purpose of the Study:

• To identify factors linked to underweight and overweight/obesity in Korean elementary school children.
• To inform targeted public health strategies for weight management in this demographic.

Main Methods:

• A cross-sectional study involving 4,895 children from 59 elementary schools in Korea.
• Children categorized based on body mass index (BMI)-for-age percentiles: underweight, normal weight, and overweight/obese.
• Data collected via questionnaires on demographics, health status, diet, exercise, and school environment.

Main Results:

• Twelve percent of children were classified as overweight or obese.
• Underweight associated with age, gender, atopic dermatitis, poor subjective health, unbalanced diet, and diet experiences.
• Overweight/obesity linked to age, gender, poor subjective health, fast food consumption, diet experiences, and rural school environments.

Conclusions:

• Behavioral factors (diet, exercise, eating habits) significantly impact children's weight status.
• Environmental characteristics of schools, such as location, also play a role.
• Interventions must adopt a holistic approach, considering both individual behaviors and the broader school environment.
