Enabling Healthy Living: Spatiotemporal Patterns of Prevalence Of Overweight and Obesity among Youths in the United States Presented: Los Angeles CA, Association of American Geographers Annual Meeting, April 2013 Cohort(s): NLSY97 Publisher: Association of American Geographers Keyword(s): Body Mass Index (BMI); Geographical Variation; Modeling; Obesity; Weight Permission to reprint the abstract has not been received from the publisher. The increasing burden of obesity in the U.S demands a better understanding of its local and regional patterns and trends. This study identifies the spatial differences in the prevalence of overweight and obesity in U.S youths using a synthesis of a cohort of large, nationally representative, longitudinal data sets, the National Longitudinal Survey of Youth 1997 (NLSY`97). Spatial and statistical methods used included the ordinary least square model, spatial generalized linear mixed model, Kulldorff's Scan space-time analysis, and spatial interpolation techniques. We analysed 12 waves (1997-2008) of data from the NLSY'97 data sets with sample sizes ranging from 6,923 to 8,565. We observed a rise in youth overweight and obesity prevalence, body mass index (BMI) was not associated with urban-rural differences, BMI was indeterminately associated with age and gender, and BMI was higher in some regions than others during the study period. Significant cluster years from the space-time analysis for high rates were detected in 2003–2008 (relative risk 1.92, log likelihood 718.6, 3.4 annual prevalence cases per 100000, p < 0.0001) and that of low rates in 1997–2002 (relative risk 0.39, log likelihood 434.3, 1.0 annual prevalence cases per 100000, p < 0.0001). Three meaningful spatiotemporal clusters of obesity were detected in counties located within the South, Lower North Eastern, and North Central regions. This study provides a spatiotemporal perspective and new evidence of heightened youth overweight and obesity in clearly defined locations. These findings can help guide geographically-targeted programs, policies, and preventive initiatives for overweight and obesity. |
