Adolescent Overweight and Obesity: A Geographic Inquiry
MetadataShow full metadata
This study analyzed the variances of BMI status of adolescents based on their dietary intake, physical activity, and method of weight loss methods among five urban school districts across the United States. Variances in nutrition and physical activity environments across five school districts was also examined as well as their possible relationship with BMI status. Multinomial logistic regression was used to analyzed BMI status and dietary intake, physical activity, and weight loss methods across each school district. The Kruskall-Wallis test was used to examine the variances in nutrition and physical activity environments among all school districts. Variances between two different school districts was determined by using the Mann-Whitney test.
Taking diet pills, powders, or liquids to lose weight was significant in three out of the five districts analyzed. Variances in access to nutritional environments as well as physical activity environments were seen among all school districts. A relationship among school districts and the access to nutritional environments, physical activity environments and BMI status could not be found.
In conclusion, BMI status is more related to weight loss methods, taking diet pills, powders or liquids and age, than physical activity and dietary intake. A relationship between BMI status and access to nutritional and physical activity environments could not be determined. Although, a significant variance was found across school districts in both nutritional and physical activity environments.
