Non Technical Summary
Childhood obesity levels in the United States have risen since the 1980's and spurred some commentators to label this rise as an "obesity epidemic. " In North Carolina, data from 2007 indicate that 33.5% of children aged 10-17 years are overweight or obese (making North Carolina 38th in the nation). Researchers have documented differentials in obesity rates by race, ethnicity, and socioeconomic characteristics. Researchers have also examined the characteristics of communities and places that result in an environment being classified as obesogenic, because its characteristics (e.g., poverty; lack of grocery stores) are associated with high levels of obesity. This project will examine the role of individual, school-level, and community/environmental factors in childhood obesity, paying special attention to the structural factors in the environment that result in differential odds for childhood obesity by race, by school characteristics, and by community (county) characteristics. In addition, the characteristics of rural counties that may be associated with higher levels of childhood obesity will be examined in the multi-level statistical models

Goals / Objectives
Using existing data from 3rd-5th grade students in North Carolina and a school-level and county-level database to be constructed from publically available sources, the objectives of the proposed project are1) To investigate how individual-level, school-level, and community (county) level variables determine the odds of childhood obesity.2) To investigate at the school-level, the role of racial segregation and the role of socioeconomic segregation, on the likelihood of childhood obesity.3) To explore and investigate what, if any characteristics of obesogenic environments impact the likelihood of childhood obesity, through the inclusion of county-level variables in the multi-level models.4) To explore and investigate what, if any, characteristics of rural counties impact the likelihood of childhood obesity, as compared to urban counties, net of individual-level and school-level effects.
Project Methods
The individual-level data for this project are based on physical education teacher's measurements and reports about 3rd-5th grade students from several hundred schools in 34 North Carolina counties. The student data come from schools in 34 North Carolina counties that represent a range in terms of their social and economic characteristics and include both rural and urban counties. Structural level data on the racial and economic characteristics of schools and of communities (counties) in North Carolina come from publically available sources. Combining these data results in a multi-level database that will be used to investigate the complex interactions between children's' obesity and individual-level, school-level, and community (county) contextual level independent variables. Multilevel logistic regression will be used to examine the complex interactions among individual-level, school-level, and community-level factors including how racial and economic segregation at the school-level is associated with increased odds of obesity, if the odds of obesity are higher for minority students as compared to white students, and whether or not students in rural counties have higher obesity rates than students in urban counties. The results contribute to an understanding of how structural factors, such as racial and socio-economic segregation, at the school and community levels, impact childhood obesity. The results will assist public policy food and health programs, such as USDA and Cooperative Extension food and nutrition programs, target their efforts at the appropriate set of factors in order to reduce childhood obesity levels.

Target Audience:Extension Professional and Staff: Rural Sociology and Public Health Professionals and Students Community Stakeholders Concerned About Childhood Obesity, Health, and Local Foods Community Development and Health Promotion Professionals at the State and Local Levels Changes/Problems:Finding appropriate county-level measures of health and social conditions for data analysis of child obesity was a problem for the data analysis of child obesity rates and local social and economic conditions. Major change was an expansion of research to include general health objectives for general population of countiesand submission of new research and grant proposals. Results used to inform research and engagment for Health Matters project: Two new proposals for new funding to expand research and including new emphases on the development of local food/ health system connections submitted to USDA NIFA and USDA Southern SARA (one grant lead to new health interventions in a set of North Carolina counties). What opportunities for training and professional development has the project provided?Training of graduate students on methods of data collection and analysis and professional publication: training on how multdisciplinary teams function and perform. Health Matters component engaged community health professionals in community mapping and health promotion techniques How have the results been disseminated to communities of interest?Presentations at professional meetings of sociologists and rural sociologists: press releases through university for general public audiences: communication with community development and health professionals at the county level about results and about methods of communinty engagement and health promotion.. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Children in rural communities have higher rates of obesity compared to their urban counterparts. Using a database on obesity among NC elementary school students, the impact of individual, school, and county-level factors including measures of the food environment, was investigated using multilevel regression models. The results of the multilevel regression models showed that a) students in rural counties were 1.25 times as likely to be obese as compared to students in urban counties, controlling for individual and school level contextual variables; students in rural counties were more likely to be obese even when county-level poverty and students' race, gender, grade, and school poverty and racial composition variables were controlled; food and built environmental variables did not account for the increased likelihood of obesity in rural counties. A related project, Health Matters, funded from the CDC, developed applied interventions to address obesity and the bulit environment and local food access in four NC counties. Results of data analysis used to inform new proposals on health, local food, and socio-ecological conditions in NC counties.

Target Audience:Rural Sociology and Public Health Faculty and Students Public School and School Health Professionals Extension Professionals and Staff Teachers, Parents, and Community Stakeholders Concerned About Childhood Obesity Prevention Changes/Problems:Many of the countyh-level measures of food access and of food and built environment (e.g., measures from the USDA-ERS food secutity databases) may not be appropriate for rural counties and using these measures can result in problems of multicollinearity, especially with others measures of socioeconomic and racial disparitity at the county-level. Continue to look for measures of food access and of the food and and built environment from Census and from USDA databases. Re-analyze the NC elementary school data with new county-level measures using multi-level regression and develop revised manuscripts from the results. What opportunities for training and professional development has the project provided?Dr. Piontak was a post-doc at Duke University and used the data and the analysis methodology as part of her research and professional development project at Duke University (she is now a researcher at Research Triangle Institute). How have the results been disseminated to communities of interest?Journal articles available to interested parties through web portals such as linked and researchgate. News stories on results of the research. What do you plan to do during the next reporting period to accomplish the goals?Continue to investigate the impact of county-level variables measuring race and socioeconomic disparities on rates of childhood obesity in the NC elementary school dataset. Search for new county-level variables and address the problem of multicollinearity among these county-level indicators. Find appropriate county-level variables for measuring food insecurity and food acess and address the problem of multicollinearity among these county-level measures. Re-analyze data using multilevel regression and investigate the factors in rural counties that impact rates of child obesity.

Impacts
What was accomplished under these goals? Children in rural communities have higher rates of obesity compared to their urban counterparts. Rural places have a unique set of economic and structural inequalities. Using a database on obesity among NC elementary school students, the impact of individual, school, and county-level factors was investigated using multilevel regression. In addition to the role of socioeconomic and racial inequality, the impact of the food environment on rates of childhood obesity was investigated with special attention directed at rural counties. The results of the multilevel regression models showed that: a) students in rural counties were 1.25 times as likely to be obese as compared to student in urban counties, controlling for individual and school context variables; 2) students in rural counties were more likely to be obese even when county-level poverty as controlled and when student's race, gender, grade, school poverty and school racial composition variables were controlled; 3) food aceess variables did not account for increased likelihood of obesity in rural counties; 4) food and build environments variables did not account for the increased likelihood of obesity in rural counties. Examing urban and rural counties together, the results show a persistent impact of rural locality on rates of childhood obesity. The increased risk of obesity among elementary school students in rural counties is not accounted for by measures of food access and measures of the food and built environment. Research results in the development of new research and engagement proposals on addressing the high rates of obesity in rural counties.

Target Audience:Sociology, Rural Sociology, and Public Health professionals and faculty Public School and School Health Professionals Teachers, Parents, and Community members concerned about student health and childhood obesity prevention. Changes/Problems:The database that was built to measure county characteristics contained a limited number of variables on the county-level food envrionment. Therefore, we decided to review existing publically available databases (e.g., the USDA-ERS food environment atlas) and to select and add approriate measures of the food environment (e.g., whether or not a county has one or more food deserts; number of food insecure families). We added variables to the county-level data base to measure the characteristics of the food environment and are investigating the possible effects of multcollinearity among these new county-level variables before including them in new multilevel models with the student and school databases. What opportunities for training and professional development has the project provided?Presentations to sociologists and social science faculty at regional professional meetings How have the results been disseminated to communities of interest?Journal articles in professional journals read by school health professionals and sociogists who work in the area of race and ethnicity and health. New releases from NC State and another from Duke University that were dessiminated to local news outlets. What do you plan to do during the next reporting period to accomplish the goals?Using the data from elementary school students in NC and the databases that have been constructed from publically avaialble data on schools and counties, we will investigate rural/urban disparities in childhood obesity reates. Using multilevel logical regression, we will model the likelihood of obesity for children in different school and community environments, including rural and comparied to urban counties. We will examine the differences beween urban and rural youth by examining differences in the socioeconomic characteristics and food environments of the county, while controlling for school and student level variables

Impacts
What was accomplished under these goals? Environments in which people live and work have well-established links to health and well-being. Research on the effects of concentrated poverty and racial segregation has often focused on either schools or neighborhoods in urban areas. This research incorporates measures of concentrated poverty and racial segregation at both the school and community level and includes both urban and rural communities. Using data from elementary public school students in North Carolina, we used multilevel logistic regression to examine the relationships among individual, school, and community level characteristics on the likelihood of obesity. Our findings indicate that children in schools and communities with low-concentrations of poverty are less likely to be obeseand children in rural areas are more likely, net the effect of individual, school, and community variables in the model. Our findings indicate that children in schools and communities with low-concentrations of poverty are less likely to be obesethan children in high poverty concentrated schools and communities according to results from the multilevel models. Multilevel logistic regression models showed that racial differences int he likelihood of obesity persisted even when racial composition and socioeconomic disadvantage at the school level were controlled. The magnitude of the effects of student-level race ont he relative odds of obesity varied according to the racial composition of the school. These student-and school-level results held even when county-level race and socioeconomic variables were controlled

In addition, children in rural areas are more likely to be obese, net the effects of individual, school, and community variables, than children in urban areas. Many policies designed to prevent or decrease obesity are directed at the individual level. These include advocating more exercise, eating less fast food, and reducing screen time among children. This research adds to this conversation by showing the importance of place-based approaches that not only address behaviors, but also ensure an environment that allows students and families to access the amenities necessary to maintain a healthy weight status.
