Sexual Orientation Differences In The Association Between Physical Activity And Allostatic Load: Results From The National Health And Nutrition Examination Study, Natalia I. Putnam

Masters Theses

Higher levels of allostatic load (AL), a composite measure of the impact of chronic stress on the body, are found among socially marginalized groups compared to privileged groups. AL is associated with premature aging and death, as well as a variety of chronic health conditions that impact quality of life. Effects of AL may be offset by physical activity (PA). Queer populations (including those who identify as lesbian, gay, or bisexual) may be at risk for elevated AL due to repeated exposure to discrimination in the form of sexual minority stress. There is mixed literature on sexual orientation differences in …

The Impact Of A Lifestyle Intervention On Risk Factors Of Cardiovascular Disease And Type Ii Diabetes Among At-Risk Hispanic Women, Kathryn A. Wagner

Doctoral Dissertations

Cardiovascular disease and type 2 diabetes are global epidemics affecting approximately 127 and 21 million people in the U.S., respectively. Women who are overweight, obese or who develop glucose intolerance during pregnancy represent high-risk groups for the development of cardiovascular disease and type 2 diabetes. Hispanic women are both more likely to begin their pregnancies as overweight or obese and have a higher prevalence of type 2 diabetes, compared to non-Hispanic whites. However, prior lifestyle interventions have largely been limited to non-Hispanic whites. Therefore, this research assessed how culturally tailored lifestyle modification may affect cardiovascular disease and type 2 diabetes …

Accelerometer-Determined Physical Behavior Metrics And Their Associations With Sarcopenia Among Oldest-Old Adults, Eric M. Eberl

Masters Theses

INTRODUCTION: Sarcopenia is a loss of muscle function and muscle mass which frequently occurs among the oldest-old adult population (aged 85+ years). The analysis of accelerometer-determined physical behavior volumes and patterns of oldest-old adults might provide novel insights into the associations with sarcopenia and its components. METHODS: A total of 145 participants in the primary sample and 87 participants in the subsample with a mean age of 88.2 (2.5) years from the Health, Aging, and Body Composition study cohort provided cross-sectional data of handgrip strength, appendicular lean mass, gait speed, and accelerometry. Probable, confirmed, and severe sarcopenia were assessed based …

A Prospective Study Of Physical Activity And Fecundability, Lindsey M. Russo

Masters Theses

Background:

Physical activity (PA) may influence fecundability through alterations in endocrine function. The limited studies that have evaluated PA and fecundability in non-clinical populations have utilized internet-based recruitment, contain potential issues in measurement, and have yielded inconclusive results.

Methods:

We evaluated the association between PA and time-to-pregnancy in the Effects of Aspirin in Gestation and Reproduction trial, which included 1228 women attempting pregnancy ages 18–40 with prior pregnancy loss. PA was measured at baseline using the short form of the International Physical Activity Questionnaire to determine hours/week of activity (vigorous, moderate, and walking) and hours/day of sedentary (sitting) behavior. Pregnancy …

Stress And Depression During Pregnancy Among Hispanic Women: Risk For Adverse Birth Outcomes And The Role Of Physical Activity, Kathleen Szegda

Doctoral Dissertations

Preterm birth and low birth weight are among the leading causes of infant mortality and morbidity in the United States. Puerto Rican women are at increased risk for these adverse birth outcomes and elevated levels of depression and psychosocial stress during pregnancy when compared to non-Hispanic Whites. Therefore, it is important to understand whether these psychological factors increase risk for these adverse birth outcomes and mechanisms to prevent/reduce depression in this high-risk population. The first study of this dissertation examined associations between perceived stress during pregnancy and preterm birth, low birth weight, and birth of a small-for-gestational age infant (SGA) …

The Role Of Sleep Timing On Diet Quality And Physical Activity Among College-Aged Women Participating In The University Of Massachusetts Vitamin D Status Study, Deniz Azarmanesh

Masters Theses

Overweight and obesity are risk factors for various chronic diseases. Sleep has been associated with overweight and obesity. One potential mechanism by which sleep may lead to overweight and obesity is through positive energy balance (i.e. energy intake exceeding expenditure). There are few studies examining the impact of sleep timing (onset and wake time) on diet and exercise. In a cross sectional study, we examined associations between sleep timing and diet quality, and in separate models, between sleep timing and meeting the 2008 Physical Activity Guidelines for Americans among the participants of the UMass Vitamin D Status Study. A total …

Recreational Physical Activity And Premenstrual Syndrome In College-Aged Women, Aimee R. Kroll

Masters Theses 1911 - February 2014

It is estimated that up to 85% of premenopausal women experience at least one premenstrual symptom and 15-20% meet clinical criteria for premenstrual syndrome (PMS). PMS has a high morbidity level and reduces the quality of life for many women of reproductive age, with pharmaceutical treatments having limited efficacy and substantial side effects. Physical activity has been recommended as a method of reducing menstrual symptom severity. However, little evidence exists to support a clear relationship between physical activity and PMS. Using a cross-sectional design, we evaluated the relationship between physical activity and PMS and menstrual symptoms among 186 women aged …

Physical Activity And Maternal/Fetal Outcomes In A Pregnant Latina Population, Audra L Gollenberg

Doctoral Dissertations 1896 - February 2014

Physical activity guidelines encouraging activity among healthy pregnant women have been issued by the Centers for Disease Control and Prevention, yet Latina women remain more sedentary than non-Latina white women. Latina women are also at higher risk for gestational diabetes mellitus and, among Latina women, Puerto Rican women have the highest rates of low birth weight and preterm-related infant death. This dissertation utilized data from the Latina GDM study, a prospective cohort study of 1,231 Latina women recruited early in pregnancy and followed through delivery. Participants were interviewed in early and mid pregnancy for assessment of sociodemographics, acculturation, medical, and …
