Objectives: This research aims to assess the prevalence of obesity among middle school students in Romania, identify associated risk factors, and propose comprehensive prevention strategies. Childhood obesity is a significant public health concern globally, and addressing it during the middle school years is crucial for long-term health outcomes.

Prior Work: Recent data from the National Institute of Statistics indicate a concerning trend: approximately 20% of children and adolescents aged 6 to 17 in Romania are overweight or obese. This prevalence has increased significantly in recent years, reflecting a growing public health issue.

Approach: A sample of 166 middle school students from Oradea-Bihor County (Romania), including 84 girls and 82 boys, participated in the study. Anthropometric measurements were conducted to assess weight, height, body mass index (BMI) and body composition. The study found that 18% of the students were classified as obese. Poor dietary habits and insufficient physical activity were prevalent among students.

Results: The results revealed that the average weight for boys is 59.53 kg, while for girls it is 55.03 kg. The average age is 14.02 years. Additionally, the average BMI is 27.78, with boys having an average BMI of 30.10 and girls 25.52. The average obesity grade is 101.13, with the lower limit being 90 and the upper limit being 125. Notably, 23 boys were found to be below the lower limit, while 27 were above the upper limit.

Implications: These findings have important implications for academics, researchers, and administrators of educational institutions in Romania. With a growing prevalence of childhood obesity, targeted interventions are urgently needed to address this issue. Strategies should include educational programs, creating supportive school environments, involving parents, and engaging with the community.

Value: The key contribution of this paper lies in its comprehensive approach to obesity prevention among middle school students in Romania. By integrating evidence-based strategies and addressing the unique needs of this age group, this research provides valuable insights for practitioners and policymakers working in the field of public health and education.
