The Role Of Physical Activity Enjoyment In The Pathways From Social And Physical Environments To Physical Activity Of Early Adolescent Girls, Elizabeth Lauren Budd

Arts & Sciences Electronic Theses and Dissertations

In 2013, only 27.1 % of adolescents (age 10-19) met the daily physical activity (PA) recommendations of 60 minutes of PA a day. 1 Inactivity is highly prevalent among youth and especially prevalent among adolescents. This inactivity can have harmful and costly, immediate and long-term repercussions on physical, mental, and social health.28 Health behaviors throughout childhood, including PA, are predictive of health behaviors throughout adulthood.9 Girls experience the steepest decline in PA in early adolescence compared to boys and any other age group, which positions them on a lifelong trajectory of inactivity and increased risk for disease.2,4 Among early adolescent …

Refining Associations Between Targeted Genes And The Development Of Substance Use Disorders, Emily Olfson

Arts & Sciences Electronic Theses and Dissertations

Recent genome-wide association studies (GWAS) provide strong evidence for the contribution of a few specific genes to alcohol and nicotine dependence. Chapter 2 explores numerous previously identified candidate genes for alcohol dependence using a publicly available GWAS. I found that many candidate loci do not replicate, highlighting the utility of GWAS for focusing on disease associated genes. Chapters 3-5 dissect associations between three genome-wide significant genes and substance use disorders. Chapter 3 focuses on a functional variant in alcohol dehydrogenase (ADH) 1B. Through examining 1,550 adolescent drinkers in the Collaborative Study on the Genetics of Alcoholism (COGA), I extended adult …

Social Support And Intimate Partnerships In African American Women With Breast Cancer, Tess Thompson

Arts & Sciences Electronic Theses and Dissertations

This mixed methods study investigated social support in African American breast cancer patients in one Midwestern metropolitan area. The study includes a quantitative analysis of social support in 227 African American breast cancer patients participating in a quality of life study, as well as a qualitative component involving a subsample of 15 married participants. In the larger sample, growth curve models were used to assess factors contributing to initial levels of perceived social support and change in social support over time. Interviews with women in the qualitative study allowed an in-depth exploration of how breast cancer affected womens relationships with …

Can We Walk? Environmental Supports For Active Travel In India, Deepti Adlakha

Arts & Sciences Electronic Theses and Dissertations

Background: Rapid rates of increase of obesity, diabetes, and associated chronic and co-morbid non-communicable diseases (e.g., cardiovascular diseases and some cancers) are being documented in India, yet in-country evidence-based research of associated risk factors is lacking. Physical activity has been identified as a preventative factor to counter the risk from obesity-related non-communicable diseases. Built environment supports for physical activity represent promising strategies to curb the rise in non-communicable diseases. Mounting research evidence suggests that the built environment can facilitate or constrain physical activity. However, a majority of this research has been conducted in developed nations. Built environment correlates of physical …

A Social Network Analysis Of Active Transportation Policy Networks, Marissa Zwald

Arts & Sciences Electronic Theses and Dissertations

Background: In an effort to increase physical activity, communities are recognizing the importance of policy and environmental changes to facilitate active transportation. However, evidence on the policy partnerships and processes to achieve such policy and environmental changes, particularly in non-health sectors, is lacking.

Methods: An online social network survey was administered in Fall 2015 to organizations engaged in active transportation policies in six cities across the United States. In addition to individual and organizational characteristics, relationships between organizations were assessed, including: level of collaboration around active transportation policies, frequency of contact, resource sharing to support active transportation, and perceived decisional …
