Childhood obesity is a complex public health issue with significant implications for long-term health outcomes and healthcare costs. This study investigates the determinants of childhood obesity, focusing on socioeconomic and environmental factors. Data were collected from 310 children and their families using a structured questionnaire from Jodhpur City. Socioeconomic variables included parental education level and household income, while environmental factors encompassed access to healthy food options and safe outdoor spaces for physical activity. Multiple regression analysis examined the relationship between these factors and childhood obesity, controlling for potential confounders. Results indicate that parental education level and household income were inversely associated with childhood obesity, suggesting that higher socioeconomic status may protect against obesity risk. Additionally, access to healthy food options in the neighborhood emerged as a significant predictor of childhood obesity, highlighting the importance of environmental factors in shaping dietary behaviors. These findings underscore the need for multifaceted interventions targeting socioeconomic disparities and ecological barriers to promote healthy weight among children. Effective strategies may include improving access to nutritious foods and creating supportive environments for community physical activity. Addressing the determinants of childhood obesity is crucial for mitigating its adverse health effects and reducing the burden on healthcare systems.
