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.

The increasing burden of overweight and obesity in the United States (U.S.) demands a better understanding of its local and regional spatial patterns and trends. The study examines the hypothesis that there are spatial differences in the prevalence of overweight and obesity in U.S. youths at regional and local levels. It used spatial, statistical, and spatiotemporal analyses and a synthesis of regionally and locally relevant data from a cohort of large, nationally representative, longitudinal data sets, the National Longitudinal Survey of Youth (NLSY97) to analyze overweight and obesity prevalence. Specifically, the methods used included the spatial Generalized Linear Mixed Model (GLMM), spatial interpolation techniques (Inverse Distance Weighting -- IDW), and Kulldorf's scan space-time analysis. The paper analyzed 12 waves (1997-2008) of data from the NLSY data sets. Its findings revealed there is an upward trend both in males and in females in obesity prevalence in US youths during the twelve-year period. Youth obesity prevalence was also higher among females than among males. The cohort shows evidence of increase in overweight and obesity prevalence. There are mixed trends in youth obesity prevalence patterns in rural and urban areas. Counties identified as consistently experiencing higher prevalence of obesity and with the potential of becoming an obesogenic environment are Copiah, Holmes, and Hinds in Mississippi; Harris and Chamber, Texas; Oklahoma and McCain, Oklahoma; Jefferson, Louisiana; and Chicot and Jefferson, Arkansas. The twelve-year study indicated spatial variation in obesity and overweight prevalence among U.S. youths, with pockets of clustered prevalence. This information can guide programs, policies, and initiatives for obesity prevention at regional and local levels.
