Insights
Childhood obesity risk factors in Spanish children include high sweetened beverage and screen time consumption. Protective factors involve dairy intake, nut consumption, adequate sleep, and positive emotional well-being.
Area of Science:
- Pediatric Health
- Public Health Nutrition
- Childhood Obesity Research
Background:
- Childhood obesity presents a significant public health challenge in Europe.
- Identifying modifiable risk factors is crucial for effective prevention strategies.
Purpose of the Study:
- To investigate lifestyle-related risk factors for overweight and obesity in Spanish children aged 3-12 years.
- To inform targeted interventions for promoting healthy lifestyles in school settings.
Main Methods:
- Cross-sectional study involving 1075 children (3-12 years) from the 'Alimentando el Cambio' project.
- Objective measurements of height and weight, alongside parental questionnaires on lifestyle behaviors.
- Statistical analysis to determine associations between lifestyle factors and Body Mass Index (BMI) z-scores.
Main Results:
- Positive associations found between sweetened beverage intake, total screen time, and BMI z-score.
- Negative associations observed between dairy product consumption and BMI z-score in girls.
- Protective effects identified for nut consumption (girls 6-12y), adequate weekday sleep, and positive emotional well-being (girls 6-12y).
Conclusions:
- Sweetened beverages and excessive screen time are significant risk factors for childhood obesity.
- Dietary factors (dairy, nuts), sleep duration, and emotional well-being play important roles in weight management.
- Interventions should address these identified factors to combat childhood obesity effectively.
Abstract:
Childhood obesity is one of the main public health concerns in Europe. The aim was to identify possible risk factors associated with overweight/obesity in Spanish preschool and school-age children. The sample (1075 (50.7% girls) children aged 3 to 12) is part of the project 'Alimentando el Cambio' whose objective is to promote healthy lifestyles in schools. Child height and weight were measured, and parents filled out questionnaires related to the children's lifestyle. There was a positive and significant association between sweetened beverage consumption and body mass index (BMI) z-score in both sexes and age groups. There was a negative and significant association between BMI z-score and dairy products in girls of both age groups. There was also a protective effect of regular nut consumption on overweight/obesity in girls 6-12 y. Night-time sleep during weekdays showed a negative association with BMI z-score for older boys and girls. A positive and significant association was found between total screen time and BMI z-score during weekdays. Regarding emotional well-being and self-esteem, having girls 6-12 y laughing and feeling happy and good about themselves in the last week was a protective factor against overweight/obesity. Childhood obesity prevention efforts may benefit from targeting these key risk factors.
