Abstract

Childhood obesity is a global epidemic and a serious issue for children and adolescents in the United States. Despite recognition of its dangers, obesity remains a public health concern, with both genetic and environmental factors contributing to its prevalence. Of particular concern is the higher obesity rates among Hispanic children, who face disproportionately significant psychological and physical health risks. Using the theory of planned behavior, this study aimed to investigate the lack of knowledge regarding gender differences in weight perceptions and intentions, the relationship between physical activity and weight perception, and the role each may play in obesity among Hispanic youth in the U.S., controlling for age and grade level. This cross-sectional study analyzed data from the 2021 National Youth Risk Behavior Survey (YRBS), including all students who responded to the survey questions relevant to the study’s variables and identified as Hispanic (n =1948). Multiple logistic regression was used to examine associations between gender, weight perception, weight intentions, and physical activity. The analysis found significant associations between these factors. Gender was a significant predictor of weight perception (χ2(4) = 19.045, p = .001) and weight intentions (χ2(3) = 56.236, p < .001), suggesting that males and females perceive their weight differently and have distinct intentions for weight management. Physical activity was also associated with weight perception (χ2(28) = 67.268, p < .001), suggesting that activity levels may influence how individuals perceive their weight. These findings highlight the importance of considering gender and physical activity when addressing childhood obesity, encouraging healthy weight management, and promoting healthier lifestyles for youth.
