Around 46.2 million Americans living in rural areas are disproportionately burdened by health disparities. Likewise, obesity and obesity-associated diseases (e.g., diabetes, cardiovascular disease) are much higher for rural residents when compared to their urban counterparts. There is a high need to understand and address the nutritional determinants of these health inequities among adults and adolescents. One area of concern in rural dietary habits pertains to added sugars and more specifically, sugar-sweetened beverages (SSB). Excessive added sugars and SSB intake have been strongly linked to many of the nutrition and chronic disease disparities impacting rural residents. Moreover, studies conducted in rural populations have found high consumptions of these in both adults and adolescents. There is an opportunity to better understand added sugars and SSB patterns in rural populations to inform the development of culturally relevant, multi-level interventions that address high consumption. Study #1 is a cross-sectional study that explores top food and beverage sources of added sugars in the diet of adults (n = 301) living in rural areas of Southwest Virginia. Study #2 uses a nationally representative sample of adolescents (n = 1,560) from the Family Life, Activity, Sun, Health and Eating (FLASHE) study sponsored by the National Cancer Institute, to explore factors across the levels of the socioecological model associated with adolescent SSB intake. Study #3 utilizes focus groups and a pilot trial to understand language preferences, acceptability and use of SMS aimed at caregivers to reduce SSB intake in both caregivers and adolescents living in rural areas of Southwest Virginia (n = 33). Collectively, these three studies offer recommendations and culturally relevant strategies for future large-scale trials aimed at reducing SSB intake among adolescents and caregivers in rural communities and ultimately reducing rural health disparities. / Doctor of Philosophy / Rural populations in the United States are at higher risk for being diagnosed with and dying from preventable and obesity-associated diseases like heart disease and cancer. Excessive added sugars and sugary drink (i.e. sodas, sweet tea/coffee, energy drinks, sweetened fruit drinks, sports drinks) intake have been strongly linked to many of the chronic diseases afflicting rural residents. Moreover, studies conducted in rural populations have found high consumptions of these, in both adults and adolescents. There is a great need to better understand added sugars and sugary drink patterns in rural populations so that we can develop programs to reduce consumption that are also culturally well received. Study #1 in this dissertation explores top food and beverage sources of added sugars in the diet of 301 adults living in rural areas of Southwest Virginia. Study #2 uses a nationally representative sample of 1,560 adolescents to explain why adolescent SSB intake might be higher. Study #3 aims to understand language preferences, acceptability and use of a text message program to reduce sugary drink intake in both caregivers and adolescents living in rural areas of Southwest Virginia. Collectively, these three studies offer recommendations and culturally relevant strategies for future large scale trials aimed at reducing sugary drink intake among adolescents and caregivers in rural communities and ultimately improving rural health.
