Methods: A non-experimental cross-sectional descriptive study was conducted among 150 school-going children aged 10-18 years in Western Maharashtra. Data were collected using structured questionnaires assessing socio-demographic factors, knowledge and self-reported practices. Descriptive and inferential statistical methods were used for data analysis.

Results: Findings revealed that 60% of children had moderate knowledge about obesity, 25% had good knowledge, and 15% had poor awareness. Awareness about dietary factors was high (70%), while knowledge of physical activity (45%) and clinical interventions (30%) was relatively low. A significant positive correlation (r = 0.65, p< 0.05) was found between knowledge and self-reported practices, indicating that higher awareness led to better health practices. Regression analysis (β = 0.58, p< 0.05) confirmed that knowledge significantly predicted healthier behavior. Demographic analysis showed that knowledge levels increased with age (F = 4.21, p< 0.05), and higher family income was associated with greater awareness (χ² = 10.45, p< 0.05). The Mann-Whitney U test (U = 532.5, p< 0.05) indicated that males had significantly higher physical activity levels than females.

Discussion: The study highlights the gap between knowledge and practical implementation of obesity prevention strategies. School-based interventions, parental involvement, and community awareness programs are essential to address this issue effectively.

Conclusion: The study underscores the need for structured educational initiatives to enhance awareness and promote healthier lifestyle practices among school-going children. Healthcare professionals, educators, and policymakers should collaborate to mitigate the risks of childhood obesity through targeted interventions.
