Predicting Exercise Adherence In College Students Using A Self-Determination Theory Framework, Megan M. Clarke

Master's Theses

College is a pivotal time for weight gain and unhealthy behavior changes in many young adults. Decreases in physical activity are common in this age group and likely contribute to the 1.6 to 1.8 kg weight gain that is often observed in the first year of college. Identifying groups of students who are at high-risk for decreasing or discontinuing physical activity may help develop more targeted interventions. The present study explored physical activity patterns in the first semester of college and examined predictors of exercise decreases to levels below recommended daily values within a Self-Determination Theory framework. Incoming freshman (n=174; …

Cardiorespiratory Fitness Reduces The Risk Of Incident Hypertension Associated With A Parental History Of Hypertension, Robin P. Shook, Duck-Chul Lee, Xuemei Sui, Vivek Prasad, Steven P. Hooker, Timothy S. Church, Steven N. Blair

Faculty Publications

Family history of hypertension increases the risk of an individual to develop hypertension, whereas moderate-to-high cardiorespiratory fitness has the opposite effect. However, the joint association of each on the development of hypertension is not well understood. We studied fitness and incident hypertension in 6278 participants who were given a preventative medical examination. Thirty-three percent reported a parent with hypertension, and there were 1545 cases of incident hypertension after a mean of 4.7 years. The presence of parental hypertension was associated with a 28% higher risk of developing hypertension after adjustments for age, sex, and examination year. After further adjustments for …

Predictors Of Weight Loss Success: Exercise Vs. Dietary Self-Efficacy And Treatment Attendance, Shannon Byrne, Danielle Barry, Nancy M. Petry

UCHC Articles - Research

Pre-treatment diet and exercise self-efficacies can predict weight loss success. Changes in diet self-efficacy across treatment appear to be even stronger predictors than baseline levels, but research on changes in exercise self-efficacy is lacking. Using data from a pilot study evaluating tangible reinforcement for weight loss (N = 30), we examined the impact of changes in diet and exercise self-efficacy on outcomes. Multiple regression analyses indicated that treatment attendance and changes in exercise self-efficacy during treatment were the strongest predictors of weight loss. Developing weight loss programs that foster the development of exercise self-efficacy may enhance participants’ success.

Fitness Tax Credits: Costs, Benefits, And Viability, Daniel M. Reach

Northwestern Journal of Law & Social Policy

As the number of overweight and obese Americans rises, it becomes increasingly clear that Americans need further incentives to stimulate lasting lifestyle changes. Tax incentives focused on exercise, which have been largely unexplored to this point, are an effective response to the growing obesity problem in the United States that would largely avoid the political opposition that tax policies focused on diet have encountered. In addition, they would also provide a more palatable solution for the taxpayer beneficiaries with a relatively low impact on government revenues. Viable tax incentives to encourage greater fitness include tax credits and sales tax breaks, …
