Insights
Childhood obesity is rising in Thailand, particularly in urban settings. Socioeconomic status significantly influences obesity rates among children in this Asian developing country.
Area of Science:
- Public Health
- Pediatrics
- Epidemiology
Background:
- Childhood obesity is a growing global concern, especially in developing nations.
- Understanding the prevalence and contributing factors is crucial for intervention.
Purpose of the Study:
- To determine the prevalence of childhood obesity in Saraburi Province, Thailand.
- To investigate the association between socioeconomic status and childhood obesity.
Main Methods:
- A cross-sectional study was conducted with 1,157 children from Saraburi Province.
- Nutritional status was assessed using weight-for-height index; socioeconomic status was determined via parental questionnaires.
Main Results:
- The prevalence of childhood obesity was 22.7% in urban areas and 7.4% in rural areas.
- Significant correlations were found between childhood obesity and parental education and household income.
Conclusions:
- Childhood obesity is an emerging public health issue in urban areas of developing Asian countries.
- Socioeconomic status is a key determinant in the prevalence of childhood obesity.
Objective:
To describe the prevalence of childhood obesity in a moderately industrialized province in Thailand and examine the influence of socioeconomic status (SES) on childhood obesity.
Design:
Cross-sectional study.
Subjects:
One thousand one hundred and fifty seven children in the second or third grade of kindergartens in Saraburi Province, Thailand.
Measurements:
Height and weight were measured and the weight-for-height index with the Thai national standard was used for assessing nutritional status. A questionnaire was used for measuring parents' socioeconomic status.
Results:
The prevalence of childhood obesity over 97th percentile for weight-for-height (>p(97)) was 22.7% in urban and 7.4% in rural areas. There were marked relationships between childhood obesity and parents' educational level and household income.
Conclusion:
Childhood obesity is an emerging health problem in developing countries, especially in urban areas. This study demonstrates a marked correlation between SES and prevalence of childhood obesity in an Asian developing country.
