Insights
Childhood obesity is rising in Serbia. Between 2015 and 2019, overweight and obesity rates increased significantly in primary school children, highlighting the need for public health action.
Area of Science:
- Public Health
- Pediatrics
- Epidemiology
Background:
- Childhood obesity is a significant global public health concern.
- Monitoring nutritional status in children is crucial for early intervention.
- The WHO European Childhood Obesity Surveillance Initiative (COSI) provides valuable data.
Purpose of the Study:
- To analyze trends in overweight and obesity prevalence among Serbian primary school children.
- To compare data from the 2015 and 2019 COSI-Serbia rounds.
- To assess the impact of overweight and obesity on child health in Serbia.
Main Methods:
- Cross-sectional study design utilizing nationally representative samples.
- Data collected during 2015 and 2019 COSI-Serbia rounds.
- Standardized measurement of height and weight, calculation of Body Mass Index (BMI), and classification using WHO and International Obesity Task Force (IOTF) criteria for children aged 7-9 years.
Main Results:
- A statistically significant increase in the combined prevalence of overweight and obesity was observed between 2015 and 2019.
- Using WHO definitions, the prevalence rose from 30.7% to 34.8% (p < 0.05).
- Using IOTF standards, the prevalence increased from 22.8% to 30% (p = 0.00).
Conclusions:
- The prevalence of childhood overweight and obesity is increasing in Serbia.
- Continuous monitoring and surveillance of children's nutritional status are essential public health priorities.
- These findings underscore the need for targeted interventions to address childhood obesity in Serbia.
Abstract:
The aim of the study was to examine changes in obesity prevalence among primary school children in Serbia between 2015 and 2019 rounds of the national WHO European Childhood Obesity Surveillance Initiative (COSI-Serbia). Cross-sectional studies were conducted in 2015 and 2019. The nationally representative samples of primary school children were measured for body height and weight, following the COSI protocol. Body Mass Index was calculated, and the IOTF and WHO definitions were used to classify children as overweight or obese. Participants were children of both sexes aged 7.00-8.99 years (n = 6105). Significant differences in overweight (obesity included) prevalence between two COSI rounds were identified regardless of definitions applied. According to the WHO definitions, prevalence of overweight and obesity combined increased in 7-9-year-old children in Serbia from 30.7% in 2015 to 34.8% in 2019 (z = -3.309, p < 0.05), and according to the IOTF standards, the increase from 22.8% to 30% was registered (z = -6.08, p = 0.00). The childhood overweight/obesity rate is increasing in Serbia, which places monitoring and surveillance of children's nutritional status high on the public health agenda.
