Description
The purpose of this thesis project was to examine the trajectories of physical activity among newly-diagnosed Obstructive Sleep Apnea (OSA) patients within the UC+WS group of the SleepWell24 study across the first 60 days of CPAP use, alone and based on Apnea-Hypopnea Index (AHI), Body Mass Index (BMI), sex, and age. The study utilizes objective data from the SleepWell24 randomized controlled trial conducted by a collaborative research team at Arizona State University and Mayo Clinic Arizona and Rochester. Participants use wearable sensors to track activity behaviors, such as sleep, sedentary behavior, light-intensity physical activity (LPA), and moderate-vigorous physical activity (MVPA). The primary aim of the study was to examine the physical activity trajectories among newly-diagnosed OSA patients over the first 8 weeks of CPAP use, utilizing the physical activity data from wearable sensors. The secondary aim was to assess the trajectories of physical activity between categories of AHI, BMI, sex, and age. Multilevel modeling was used to account for clustering within participants considering between and within subject variations, and week was used as a level 1 predictor in the model for LPA, and MVPA, and total activity (sum of LPA and MVPA), while between subject factors of BMI, sex, age, and AHI were also included in the model. It was found that there were no statistically significant trajectories of LPA, MVPA or total activity over the first 8 weeks of CPAP use within the sample of 30 participants. However, a few notable differences in physical activity were seen between categories of age, sex, and BMI. Also, there was a significant interaction found between BMI and each week that influenced the trajectory of physical activity within obese patients, as compared to participants considered overweight or with a lower BMI. Ultimately, this study provides insight into patterns of physical activity seen in a clinical population of OSA patients over the initial period of CPAP use.

Description
Objective: The purpose of this research project was to determine if there are nutritional disparities between students of differing socioeconomic status (SES) households. The SES was determined using school classifications (i.e., title one versus non-title one) as a proxy measure. It was hypothesized that children attending a title one school would consume a greater amount of sugary drinks than students attending a non-title one school Participants: The parents/guardians of students in grades 3rd and 4th, from a title one school and from a non-title one school. Methods: The data were gathered from surveys that were sent home to the parents/guardians of the students. The surveys inquired about how many bottles of water, juice boxes, glasses of milk, cans of soda, bottles of Gatorade, and cans of energy drinks their child consumes on a single weekend day. Statistical Analysis: Shapiro Wilk tests were used for normality. Differences in the consumption of sugary drinks were analyzed using the Mann Whitney U test. Results: A total of 150 surveys were returned by students from both schools (n=57 from the title one school; n = 93 from the non-title one school). The results showed a median of 1.00 (IQR=1.25, 4.50) sugary drink for the non-title one school and 3.00 (IQR=0.00, 2.00) sugary drinks for the title one school. The results from the Mann-Whitney U Test showed a significant difference in consumption in sugary drinks between schools (U = 1509.00, p < 0.001). Conclusion: Students attending a title one school consumed a greater amount of sugary drinks than students attending a non-title one school. Parents are a strong contributor to the nutritional diet of children, however students of this age are developing self-efficacy to make their own choices regarding the food and drinks they consume. Researchers can intervene by increasing student and parent knowledge and by researching the effectiveness of instructions based on the new knowledge.

Description
There has been a rise in the prevalence of mental health disorders among western industrialized populations.1 By 2020, depression will be second to heart disease in its contribution to the global burden of disease as measured by disability-adjusted life years.2 Anxiety disorders are the most common mental illness in the U.S., affecting 40 million adults in the United States ages 18 and older, or 18.1% of the U.S population every year.3
Mental disorders are prevalent in young adults and frequently present between 12-24 years of age.4 The top five sources of stress reported by college students were changes in sleeping routines, changes in eating habits, increased amount of work, new responsibilities, and breaks/vacations.5 Overall, a total of 73% of college students report occasional difficulties sleeping, and 48% of students suffer from sleep deprivation, as self-reported.6,7
Lifestyle factors such as diet, exercise and sleep may influence symptoms related to stress and depression.8 Symptoms of depression include but are not limited to, persistent anxious or sad moods, feeling guilty or helpless, loss of interest in hobbies, irritability, and other behaviors that may interrupt daily living.9 Inadequate intake of folic acid from fruits and vegetables, and essential fatty acids in fish, may increase symptoms of depression.10 Unhealthy eating habits may be associated with increases in depression-like symptoms in women, supporting the notion that healthier eating habits may decrease major depression.11 Diet is only one component of how lifestyle may influence depression and stress in adults. Exercise may be another important component in decreasing depression-related symptoms due to the release of endorphins.12 It has been found that participating in regular physical activity may decrease tension levels, increase and stabilize mood, improve self-esteem, and lead to better sleeping patterns.13 It has been concluded that individuals who consume a healthy diet are less likely to experience depression whereas people eating unhealthy and processed diets are more likely to be depressed.14
Poor sleep quality as well as unstable sleeping patterns may lead to poor psychological and physical health.15 Poor sleep includes longer duration of sleep onset latency, which is defined as the amount of time it takes to fall asleep, waking up multiple times throughout the night, and not getting a restful sleep because of tossing and turning.16 In healthy adults, the short-term consequences of sleep disruption consist of somatic pain, emotional destress and mood disorders, reduced quality of life, and increased stress responsivity.17 Irregular sleep-wake patterns, defined as taking numerous naps within a 24 hour span and not having a main nighttime sleep experience, are present at alarming levels (more than a quarter) among college students.18 A study done with 2,000 college students concluded that more than a quarter of the students were at risk of a sleeping disorder.19 Therefore, college students who were classified as poor-quality sleepers, reported experiencing more psychological and physical health problems compared to their healthy counterparts. Perceived stress was also found to be a factor in lower sleep quality of young adults.20
The link between depression-like symptoms and sleep remains poorly understood. It is mentioned that there are risk factors of poor sleep, depression and anxiety among college students but this topic has not yet been heavily studied within this population.

Description
Objectives: The goal of this study was to compare older adults (ages 60 to 80) with a fixed sleep schedule compared to a restricted sleep schedule. The purpose was to determine if reducing one's sleep by an hour each night for 12 weeks, led to worse cognition and mood over time. Study Design: The study contained two groups: older adults with their sleep restricted and older adults with their sleep un-restricted. Participants were recruited by researchers at Arizona State University and The University of Arizona by advertising in newspapers, on flyers in senior centers, and on radio stations. After rigorous screening for health conditions, current sleep patterns and depression, individuals entered the study. Participants completed the Geriatric Depression Scale after two weeks of baseline, and again after treatment week 14 of the study. Likewise, males and females performed three cognitive tests after two weeks of baseline, and again after treatment week 14 of the study. These cognitive tests included Stroop Color and Word Test, Trail making and PVT. Results: The depression scale and three cognitive tests showed that there was no significant difference with cognition and mood over 14 weeks between individuals with a fixed sleep schedule compared to a restricted sleep schedule. Conclusions: Reducing older adult's sleep duration by an hour each night for 14 weeks does not produce negative effects, and does not provoke signs of depression or weakened cognition.

Description
Purpose: The purpose of this study was to determine the efficacy of a yoga intervention for adolescents suffering from depression. Secondary results regarding the viability of yoga as an intervention for increasing self-esteem and decreasing anxiety were also explored.
Methods: Using PubMed, Medline, and CINAHL the search terms adolescents, depression, and yoga were searched for related articles. Articles were then excluded or included based on certain criteria. Focus was placed on articles written within the last 10 years as well as studies done on children within 10-19 years of age. Final articles underwent extraction for relevant information and comparisons were drawn between the studies.
Results: Final exclusion lead to a total of 5 suitable studies. Studies varied in styles of yoga performed and measurement scales used to assess depression. Populations of adolescents varied significantly as well. The majority of these studies showed significant improvement in depression symptoms when measuring from pre to post intervention. Similar improvements were also noted in anxiety symptoms and low self-esteem.
Conclusion: Data gathered indicated that yoga serves a suitable intervention for decreasing depression symptoms in adolescents. Additionally, there seems to be promising results regarding the viability of yoga as an intervention for decreasing symptoms of anxiety and increasing self-esteem. Despite, current promising results, there is need for more research to affirm the findings found in these articles to determine the long term effects of yoga interventions.

Description
Human trafficking is not only a social injustice, but also a major global health problem, that our communities cannot ignore. Despite the common misconception that trafficking is only seen in foreign countries or is only related to immigrants, the U.S. is known to be a major trafficking market and destination, with trafficking reported in all 50 states (Bladwin et al., 2011; Shandro et al., 2016; Dovydaitis, 2010). Although trafficking victims are unlikely to have appropriate access to health care, as much as 80% of sex trafficking victims have reported that they encountered a medical professional while under their traffickers' control and went unidentified at the time (Baldwin et al., 2011; Shandro et al., 2016). This exemplifies a serious missed opportunity for intervention. Health care providers should be prepared to identify and care for victims of trafficking as part of their routine clinical practice. This thesis aims to describe trafficking victims' encounters in U.S. health care settings, to assess health care professionals' and students' awareness, knowledge, and beliefs on trafficking, to examine the impact of an educational intervention on this populations' knowledge/belief changes, and to ultimately spread education about this issue to a wide array of communities.

Description
Sleep is imperative for health and wellness with direct impacts on brain function, physiology, emotional well-being, performance and safety when compromised. Adolescents and young adults are increasingly affected by factors affecting the maintenance of regular sleep schedules. College and university students are a potentially vulnerable population to sleep deprivation and sleep insufficiency. Possible factors that could contribute to poor sleep hygiene include, but are not limited to, academic pressures, social activities, and increased screen time. Arguably, students are still experiencing bone mineralization, until the age of 30 or even 40 years old, which makes it more important to understand the effects that altered sleep patterns could have on continued development of bone health. It is our understanding that to date, studies assessing the risk of sleep insufficiency on bone mineral density in college students have not been conducted. We hypothesized that college-aged students, between the ages of 18-25 years, with shorter sleep durations, greater sleep schedule variability, and poorer sleep environments will have significantly lower bone mineral density. ActiGraph monitoring, via a wrist ActiWatch was used to quantitatively measure sleep habits for up to 7 consecutive days. During the week-long study participants also captured their self-reported sleep data through the use of a sleep diary. Participants were measured one time within the study for bone mineral density of the lumbar spine and total hip through a dual energy x-ray absorptiometry. This was a preliminary analysis of a larger cross-sectional analysis looked at 17 participants, of which there were 14 females and 3 males, (n=5, 1 and 11 Hispanic, Black and White, respectively). The mean age of participants was 20.8±1.7 y with an average BMI of 22.9±3.2 kg/m2. ActiWatch measurement data showed a mean daily sleep duration of participants to be 437.5 ± 43.1 (372.5 – 509.4) minutes. Mean sleep efficiency (minutes of sleep divided by minutes of time in bed) and mean number of awakenings were 87.4±4.3 (75.4-93.4) minutes and 32.1±6.4 (22.3-42.7) awakenings, respectively. The median time for wake after sleep onset (WASO) was 34.5±10.5 (18.3-67.4) minutes. The mean bone mineral density (BMD) for the hips was 1.06±0.14 (0.81-1.28) g/cm2 with a mean BMD of the lumbar spine being 1.24±0.12 (0.92-1.43) g/cm2. Age-matched Z-scores of the hips was 0.31±0.96 (-1.6-2.1) and lumbar spine was 0.53 (IQR: 0.13, 0.98; -2.25-1.55). Neither sleep duration nor sleep efficiency was significantly correlated to BMD of either locations. While WASO was positively associated with hip and spine BMD, this value was not statistically significant in this population. Overall, associations between sleep and BMD of the femur and spine were not seen in this cohort. Further work utilizing a larger cohort will allow for control of covariates while looking for potential associations between bone health, sleep duration and efficiency.

Description
The objective of the present study was to investigate differences in traditional and non-traditional cardiovascular disease (CVD) risk factors between Asian and non-Hispanic White young adults. The burden of CVD varies by racial/ethnic group. Traditional risk factors that increase the likelihood of developing CVD include smoking, alcohol, physical inactivity, obesity, diabetes, high cholesterol, and high blood pressure. Suboptimal sleep is known to be a non-traditional risk factor for poor overall health, CVD risk factors, and CVD. The present study was an investigation of a cross-sectional, screening survey used for a larger community-based study on sleep and cardiovascular health. The unadjusted results examining differences in traditional CVD risk factors indicated that Asian participants were less likely to report alcohol use compared to non-Hispanic White participants. For non-traditional CVD risk factors, Asians were less likely to report experiencing sleep-related fatigue or malaise, attention impairment, daytime sleepiness, reduced motivation or energy, or concerns about their sleep compared to non-Hispanic White participants. Multivariate-analyses were conducted adjusting for sex and age. The adjusted results indicated that the Asian participants were less likely to report alcohol consumption, regular engagement in exercise, engagement in hard intensity exercise, concerns with sleep quality, and sleep difficulty-related fatigue, attention impairment, daytime sleepiness, reduced motivation, and were more likely to be obese compared to non-Hispanic White participants. The results may help guide cardiovascular prevention education provided to these groups. The data indicate the need for further longitudinal research studies on non-traditional CVD risk factors like sleep by ethnicity/race.

Description
The growing Hispanic population in Phoenix, Arizona frequently lacks financial resources which may limit their access to health care. The goal of this study was to identify the ideal factors in a health insurance plan for the Hispanic/Latino population in Phoenix, AZ. A survey was designed to gather information regarding demographics, health insurance, preferences, and affordability. The survey was completed by 260 participants. Several multivariate regressions were run using SAS Statistical Software. The final model generated explained 4.48% of the variation in the data set. It showed that an individual who identified as Hispanic/Latino was 8.2% less likely to have health insurance. In addition, an individual who identified as a US Citizen was 23% more likely to have health insurance. To improve access and enrollment among the Hispanic/Latino population, further investigation is needed to identify relevant communication techniques that increase enrollment among this high-risk community.

Description
Sleep diaries and actigraphy are two common methods used to assess sleep subjectively and objectively, respectively. Compared to the gold standard of sleep assessment, polysomnography, sleep diaries and actigraphic methods are more cost-effective and simpler to use. This study aimed to compare the sleep parameters derived from actigraphy and sleep diaries (total sleep time, sleep onset latency, number of awakenings, wake after sleep onset, percentage of time awake, and sleep efficiency). Based on results from previous similar studies, it was hypothesized that the sleep diaries would overestimate the total sleep time parameter and underestimate wake parameters. Twenty healthy young adults without sleep problems volunteered to participate. The participants wore an Actiwatch 2 on their wrist and filled out a sleep diary every morning for the duration of six days. A high intraclass correlation coefficient value between subjective and objective sleep was found for the parameter total sleep time, even though total sleep time was found to be slightly overestimated by the sleep diaries. Sleep onset latency, wake after sleep onset, number of awakenings, percentage of time awake, and sleep efficiency were underestimated by the sleep diaries and did not have high correlation values. Based off of the ICC results, there does not seem to be a strong correlation between the Actiwatch 2 and the sleep diaries, but looking at the Bland Altman plots, there seems to be agreement between the methods.
