Obesity prevalence is at an alarmingly high rate within the United States, but especially in rural areas of Kentucky. Obesity can lead to a variety of negative physical health outcomes including heart disease, diabetes, stroke, and some cancers. There are also mental disorders associated with obesity through mechanisms such as weight stigma and self-perception. Similar to obesity rates, prevalence and mortality associated of these health outcomes are also seen at disproportionately higher rates in rural, Appalachian Kentucky. Causes for increased obesity and obesity related consequences include some genetic factors as well as behavioral factors like physical inactivity, poor diet, stress, …

INTRODUCTION: Behavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of individual and trial-level subgroups. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commencing antenatally or in the first year after birth, and …

Biostatistics Faculty Publications

BACKGROUND: Circulating levels of the endogenous inhibitor of nitric oxide synthase, asymmetric dimethylarginine (ADMA), are positively associated with the prevalence of metabolic syndrome (MetS) in cross-sectional investigations. It is unclear if circulating ADMA and other methylarginines are associated with incident MetS prospectively.

METHODS: We related circulating ADMA, symmetric dimethylarginine (SDMA), L-arginine (ARG) concentrations (measured with a validated tandem mass spectrometry assay) and the ARG/ADMA ratio to MetS and its components in 2914 (cross-sectional analysis, logistic regression; mean age 58 years, 55% women) and 1656 (prospective analysis, Cox regression; mean age 56 years, 59% women) individuals from the Framingham Offspring Study …

Introduction

Obesity disproportionately affects rural communities, and Appalachia has some of the highest obesity rates in the nation. Successful policy, systems, and environmental (PSE) interventions to reduce obesity must reflect the circumstances of the population. We used a health equity lens to identify barriers and facilitators for healthy food access in Martin County, Kentucky, to design interventions responsive to social, cultural, and historical contexts.

Methods

We conducted 5 focus groups in Martin County, Kentucky, in fall 2019 to obtain perspectives on the local food system and gauge acceptability of PSE interventions. We used grounded theory to identify perceived barriers and …


Time Spent Exercising And Obesity: An Application Of Lewbel’S Instrumental Variables Method, Charles J. Courtemanche, Joshua C. Pinkston, Jay Stewart Jan 2020

Time Spent Exercising And Obesity: An Application Of Lewbel’S Instrumental Variables Method, Charles J. Courtemanche, Joshua C. Pinkston, Jay Stewart

Institute for the Study of Free Enterprise Working Papers

This paper examines the role physical activity plays in determining body mass using data from the American Time Use Survey. Our work is the first to address the measurement error that arises when time use during a single day—rather than average daily time use over an extended period—is used as an explanatory variable. We show that failing to account for day-to-day variation in activities results in the effects of time use on a typical day being understated. Furthermore, we account for the possibility that physical activity and body mass are jointly determined by implementing Lewbel’s instrumental variables estimator that exploits …


Cardiac Effects Of Obesity During Pregnancy In C57bl/6j Mice, Kayla Lynn Dudick Jan 2020

Cardiac Effects Of Obesity During Pregnancy In C57bl/6j Mice, Kayla Lynn Dudick

Theses and Dissertations--Nutrition and Food Systems

Objective: Pregnancy requires profound cardiac and metabolic adaptation. Left ventricular (LV) mass is increased in response to pregnancy, but is not associated with cardiac damage. In contrast, obesity-mediated cardiac hypertrophy is pathological. Data from animal studies indicate dietary fatty acid composition may have a protective effect during states of extreme cardiac physiological adaptation. In contrast, aberrant cardiac metabolism is a hallmark of disease. Over a third of reproductive-age women in the United States are obese, but there is a paucity of data describing the effect of obesity on maternal cardiac adaptation to pregnancy. The objective of this study was to …


West Virginia’S Sugary Drink Tax: Examining Print Media Frames In Local News Sources, Lauri Andress, Ogaga Urhie, Christine Compton Jul 2019

West Virginia’S Sugary Drink Tax: Examining Print Media Frames In Local News Sources, Lauri Andress, Ogaga Urhie, Christine Compton

Journal of Appalachian Health

Introduction: Framing is an important aspect of the policy process that helps the public and decision makers sort through and resolve highly charged claims about an issue. Through slight changes in the presentation of issues, a framing effect may alter public support. The way a proposed sugary drink tax is discussed in public discourse and by the media significantly influences policy acceptance. Given the public health significance of obesity and diabetes in West Virginia (WV) the study of media frames employed to represent a sugary drink tax policy is useful.

Methods: Using quantitative content analysis, this study assessed news articles—published …

Despite existing reports on differential DNA methylation in type 2 diabetes (T2D) and obesity, our understanding of its functional relevance remains limited. Here we show the effect of differential methylation in the early phases of T2D pathology by a blood-based epigenome-wide association study of 4808 non-diabetic Europeans in the discovery phase and 11,750 individuals in the replication. We identify CpGs in LETM1, RBM20, IRS2, MAN2A2 and the 1q25.3 region associated with fasting insulin, and in FCRL6, SLAMF1, APOBEC3H and the 15q26.1 region with fasting glucose. In silico cross-omics analyses highlight the role of differential methylation …

Background: The high prevalence of obesity among US adults has resulted in significant increases in associated metabolic disorders such as diabetes, dyslipidemia, and high blood pressure. Together, these disorders constitute metabolic syndrome, a clinically defined condition highly prevalent among African-Americans. Identifying epigenetic alterations associated with metabolic syndrome may provide additional information regarding etiology beyond current evidence from genome-wide association studies.

Methods: Data on metabolic syndrome and DNA methylation was assessed on 614 African-Americans from the Hypertension Genetic Epidemiology Network (HyperGEN) study. Metabolic syndrome was defined using the joint harmonized criteria, and DNA methylation was assessed using the Illumina HumanMethylation450K Bead …


Evaluation Of Barriers For Small-Scale Fruit And Vegetable Growers In Kentucky, Amanda Schroeder Hege Jan 2018

Evaluation Of Barriers For Small-Scale Fruit And Vegetable Growers In Kentucky, Amanda Schroeder Hege

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

The food system in the United States has witnessed significant challenges resulting in food security and safety concerns, environmental damage, economic distress, and a decline in our population’s health. While the last fifty years showed a drop in land and workforce dedicated to farming, industrialized farms are producing an overabundance of cheap corn that directly supplies inexpensive, unhealthy foods leading to American’s diets falling short of recommendations for good health, thus contributing to the obesity epidemic. This study utilizes an upstream approach to learn from farmers’ ability to grow good food that promotes healthy people, environments, and communities. Specifically, the …

Cross-Sector Partnerships And Public Health: Challenges And Opportunities With The Private Sector, Lee Johnston, Diane Finegood

Frontiers in Public Health Services and Systems Research

Over the past few decades, cross-sector partnerships that include the private sector have become an increasingly accepted practice in public health, particularly in efforts to address infectious disease in low and middle income countries. Now they are becoming a popular tool in efforts to reduce and prevent obesity and the epidemic of non-communicable disease. Partnering with business presents a means of acquiring resources, as well as opportunities to influence the private sector toward more healthful practices. Collaboration is a core principle of public health practice; however public-private or non-profit-private partnerships present risks and challenges that warrant specific consideration. In this …

BACKGROUND: A short-term high-fat diet impairs mitochondrial function and the ability of skeletal muscle to respond to growth stimuli, but it is unknown whether such a diet alters the ability to respond to atrophy signals. The purpose of this study was to determine whether rapid weigh gain induced by a high-fat (HF) diet accelerates denervation-induced muscle atrophy.

METHODS: Adult, male mice (C57BL/6) were fed a control or HF (60 % calories as fat) diet for 3 weeks (3wHF). Sciatic nerve was sectioned unilaterally for the final 5 or 14 days of the diet. Soleus and extensor digitorum longus …
