Insights
Childhood obesity shows socioeconomic inequalities, with higher prevalence in wealthier families. Promoting maternal education and focusing on residential areas can help reduce these disparities.
Area of Science:
- Pediatric Endocrinology
- Public Health
- Socioeconomic Determinants of Health
Background:
- Childhood obesity is a growing global concern.
- Socioeconomic status (SES) is increasingly recognized as a significant factor influencing health outcomes, including obesity.
- Understanding socioeconomic inequalities in childhood obesity is crucial for developing targeted interventions.
Purpose of the Study:
- To assess socioeconomic inequalities in the prevalence of overweight and obesity among children aged 10-12 years.
- To identify the key socioeconomic determinants contributing to these inequalities.
Main Methods:
- A cross-sectional study involving 2506 children aged 10-12 years in Sanandaj, western Iran.
- Socioeconomic status (SES) determined using Principal Component Analysis (PCA) based on household assets.
- Concentration Index and Oaxaca decomposition used to measure and analyze socioeconomic inequalities.
Main Results:
- Prevalence of overweight was 24.1% and obesity was 11.5%.
- A significant concentration index indicated higher prevalence of overweight and obesity in higher SES groups.
- Socioeconomic factors explained 75.8% of the observed inequalities, with residential area and maternal education being the most influential.
Conclusions:
- Socioeconomic inequalities significantly contribute to childhood overweight and obesity.
- Interventions should focus on improving maternal education and addressing disparities related to residential areas.
- Targeted strategies are needed to mitigate the impact of socioeconomic factors on childhood obesity.
Background:
The aim of this study was to assess the socioeconomic inequalities in obesity and overweight in children aged 10 to 12 yr old.
Study Design:
A cross-sectional study.
Methods:
This study was conducted on 2506 children aged 10 to 12 yr old in the city of Sanandaj, western Iran in 2015. Body mass index (BMI) was calculated. Considering household situation and assets, socioeconomic status (SES) of the subjects was determined using Principal Component Analysis (PCA). Concentration Index was used to measure inequality and Oaxaca decomposition was used to determine the share of different determinants of inequality.
Results:
The prevalence of overweight was 24.1% (95% CI: 22.4, 25.7). 11.5% (95% CI: 10.0, 12.0) were obese. The concentration index for overweight and obesity, respectively, was 0.10 (95% CI: 0.05, 0.15), and 0.07 (95% CI:0.00, 0.14) which indicated inequality and a higher prevalence of obesity and overweight in higher SES. The results of Oaxaca decomposition suggested that socioeconomic factors accounted for 75.8% of existing inequalities. Residential area and mother education were the most important causes of inequality.
Conclusions:
To reduce inequalities in childhood obesity, mother education must be promoted and special attention must be paid to residential areas and children gender.
