Description
High childhood obesity rates have resulted in many interventions to attempt to lower these rates. Interventions such as day camps, residential camps, therapy-based interventions and family-based interventions lead to changes in weight and self-esteem but family-based intervention leads to the longest-term success for children ages nine to 17. Analysis of the interventions was measured using tools such as BMI, BMI-percentiles, and weight. Psychological measures such as self-esteem, happiness, and quality of life analysis was preferred, however were not measured in all studies. While most interventions resulted in weight loss and increased self-esteem, results were often not long-term. Studies provided evidence that family-based therapy has potential to last long-term, however there is a lack of research. To determine the most effective childhood nutrition intervention research must conduct follow-ups for many years after the initial intervention to ensure they provide long-term results.

Description
Ecological modeling can be used to analyze health risk behaviors and their relationship to ecological factors, which is useful in determining how social environmental factors influence an individual’s decisions. Environmental interactions shape the way that humans behave throughout the day, either through observation, action, or consequences. Specifically, health risk behaviors can be analyzed in relation to ecological factors. Alcohol drinking among college students has been a long concern and there are many risks associated with these behaviors in this population. Consistent engagement in health risk behaviors as a college student, such as drinking and smoking, can pose a much larger issues later in life and can lead to many different health problems. A research study was conducted in the form of a 27 question survey to determine and evaluate the impact of ecological factors on drinking and smoking behaviors among Arizona State University students. Ecological factors such as demographics, living conditions, contexts of social interactions, and places where students spend most of their time were used to evaluate the relationship between drinking and smoking behaviors and the ecological factors, both on- and off- campus.

Description
There has been very little research conducted on the long-term effects of exercise on children with Down Syndrome (DS), however, there is some research on Assisted Cycle Therapy (ACT) in adolescents and adults with Down Syndrome and has found positive results on motor, cognitive and mental health measure. Therefore, a grant proposal was submitted to develop ACT Early, a pediatric version of the ACT bicycle, developed in conjunction with Theracycle, geared towards early intervention in children with DS rather than adults with DS. Once submitted, the reviewers sent back their comments of why they would not fund the development of ACT Early. The comments focused on what the parents/guardians would want for their children. Therefore, the purpose of this thesis was to create a questionnaire for parents/guardians so a new grant proposal can be created based on their input and to find the effects exercise and ACT has on children with Down Syndrome. After weeks of helping create the survey based on comments from reviewers of the previously submitted grant, I collected 70 questionnaires at several events in the community. Our results showed that the exercise regimen would be most appropriate for 7-9 year old’s for 2 days a week and 30-45 min per day. The type of exercise would be light intensity on an ACT Theracycle, and it will be done in a fitness/clinical setting. Other options that were suggested were to add music or a buddy to exercise with. Additionally, straps will be used on the Theracycle to ensure maximum safety and the results will be disseminated via emails, websites, in person and through journals. In conclusion, the hope is that the changes made to the study based on this survey of parent/guardian input will help fund the development of the ACT Early Theracycle for children. This is important because early intervention in children with neurological disorders can achieve their best quality of life as soon as possible and become independent, happy, and productive in our society.

Description
Background: Natural Language Processing models have been trained to locate questions and answers in forum settings before but on topics such as cancer and diabetes. Also, studies have used filtering methods to understand themes in forum settings regarding opioid use. However, studies have not been conducted regarding training an NLP model to locate the questions people addicted to opioids are asking their peers and the answers they are receiving in forums. There are a variety of annotation tools available to help aid the data collection to train NLP models. For academic purposes, brat is the best tool for this purpose. This study will inform clinical practice by indicating what the inner thoughts of their patients who are addicted to opioids are so that they will be able to have more meaningful conversations during appointments that the patient may be too afraid to start.
Methods: The standard NLP process was used for this study in which a gold standard was reached through matched paired annotations of the forum text in brat and a neural network was trained on the content. Following the annotation process, adjudication occurred to increase the inter-annotator agreement. Categories were developed by local physicians to describe the questions and three pilots were run to test the best way to categorize the questions.
Results: The inter-annotator agreement, calculated via F-score, before adjudication for a 0.7 threshold was 0.378 for the annotation activity. After adjudication at a threshold of 0.7, the inter-annotator agreement increased to 0.560. Pilots 1, 2, and 3 of the categorization activity had an inter-annotator agreement of 0.375, 0.5, and 0.966 respectively.
Discussion: The inter-annotator agreement of the annotation activity may have been low initially since the annotators were students who may have not been as invested in the project as necessary to accurately annotate the text. Also, as everyone interprets the text slightly differently, it is possible that that contributed to the differences in the matched pairs’ annotations. The F-score variation for the categorization activity partially had to do with different delivery systems of the instructions and partially with the area of study of the participants. The first pilot did not mandate the use of the original context located in brat and the instructions were provided in the form of a downloadable document. The participants were computer science graduate students. The second pilot also had the instructions delivered via a document, but it was strongly suggested that the context be used to gain an understanding of the questions’ meanings. The participants were also computer science graduate students who upon a discussion of their results after the pilot expressed that they did not have a good understanding of the medical jargon in the posts. The final pilot used a combination of students with and without medical background, required to use the context, and included verbal instructions in combination with the written ones. The combination of these factors increased the F-score significantly. For a full-scale experiment, students with a medical background should be used to categorize the questions.

Description
Infants partake in a developmental process between birth and 18 months which takes them from small movement while lying on their anterior side, through to walking, running, and jumping. In order to properly progress through this process, infants must learn to crawl before they learn to walk; though this process can be altered by the influence of infant locomotor devices.
The use of infant locomotor devices such as walkers, jumpers, and exersaucers are widely controversial amongst parents and pediatricians. Parents often cite benefits to the child with device exposure, whereas pediatricians often warn against the use of them. The concern of the pediatricians lay within the risk that comes along with increased mobility, as well as the upright position the device puts the child in. The child is often unable to place themselves in this position outside of the device due to not being ready in their developmental pathway. The device places the child upright with their legs hanging below with their feet not flat on the ground supporting weight. This position can place strain on the infants’ hips, lower back, and trunk.
Research shows that infants with prolonged device exposure tend to reach their locomotor milestones later than infants with average to ideal exposure. Infants with prolonged device exposure have also been found to score lower on developmental assessments. To reduce the risk of injury and developmental delay, the American Academy of Pediatrics ban the production and sale of infant walkers, and advised parents allow their children to play in more natural positions, rather than the position the locomotor devices place the child in.
In order to bridge the gap of education provided to parents and caregivers, and the knowledge of the pediatricians, further research should be done to collect up to date data of the impact of these devices and the long-term impact of these devices past the age of three. Working to expand the educational outreach to parents, particularly in the medical setting, would also be beneficial in working to reduce the exposure infants have to these devices and in turn, the number of injuries and developmental delays associated with use.

Description
Purpose: Children with attention-deficit/hyperactivity disorder (ADHD) have been found to have central executive deficits in working memory as well as less academic success than children with typical development. The purpose of this study was to determine which components of central executive function were most closely related to parental rating scores of attention.
Method: Two hundred twenty three 2nd graders with typical development, dyslexia, developmental language disorder (DLD), or dyslexia/DLD completed three central executive tasks from the Comprehensive Assessment Battery for Children–Working Memory (Gray, Alt, Hogan, Green, & Cowan, n.d.). Parents of the children completed the ADHD Rating Scale-IV: Home Version for their child. None of the participants had been diagnosed with ADD/ADHD
Results: When diagnostic group performance was compared we found significant differences on each central executive task. When ADHD group performance was compared we found a significant between-group performance only on the n-back visual task with the high-risk group scoring lower than the other two groups. ADHD rating scores predicted a significant amount of variance for each central executive task, but percentages were small (3%-6%).
Discussion: Working memory is known to be related to attention control. Stronger attentional control is associated with a higher working memory performance. Our study showed that children most at risk for ADD/ADHD based on parent ratings scored lowest on the visuospatial task, likely because rehearsal of visuospatial information is not possible so relies more heavily on attention. This study is a step toward considering how attention affects working memory performance so that both can be considered when designing instruction and interventions.

Description
Granular information sharing allows patients to have more control over their medical records by giving them the choice of what information to share and with whom. Numerous studies have focused on patients’ perspectives, but this study focuses on the provider views of granular information sharing. Twenty-eight behavioral health providers (n=3 prescribers, n=25 non-prescribers) from two different integrated healthcare facilities participated in a 2-hour focus group and took a survey at the beginning and at the end of the focus group. The survey responses were analyzed using descriptive analysis to understand how the providers' preferences changed from the pre-study to the post-study. Most providers changed their view about granular information sharing, as 30% of providers “were OK with patients having control over who sees what information in their electronic health record”, previously 83%. Overall, health care providers had concerns that granular information sharing because they feared that it would lead to increased costs, patient safety issues involving drug-drug interactions, and poor provider-patient relationships.

Description
Introduction: There is currently a lack of industry-wide gold standardization in accelerometer study
protocols, including within sleep-focused studies. This study seeks to address accuracy of
accelerometer data in detection of the beginnings and ends of sleep bouts in young adults with
polysomnography (PSG) corroboration. An existing algorithm used to differentiate valid/invalid wear
time and detect bouts of sleep has been modified with the goal of maximizing accuracy of sleep bout
detection. Methods: Three key decisions and thresholds of the algorithm have been modified with three
experimental values each being tested. The main experimental variable Sleepwindow controls the
amount of time before and after a determined bout of sleep that is searched for additional sedentary
time to incorporate and consider part of the same sleep bout. Results were compared to PSG and sleep
diary data for absolute agreement of sleep bout start time (START), end time (END) and time in bed
(TIB). Adjustments were made for outliers as well as sleep latency, snooze time, and the sum of both.
Results: Only adjustments made to a sleep window variable yielded altered results. Between a 5-, 15-,
and 30-minute window, a 15-minute window incurred the least error and most agreement to
comparisons for START, while a 5-minute window was best for END and TIB. Discussion: Contrary
to expectation, corrections for snooze, latency, and both did not substantially improve agreement to
PSG. Algorithm-derived estimates of START and END always fell after sleep diary and PSG both,
suggesting either participants’ sedentary behavior beginning and ends were at a delay from sleep and
wake times, or the algorithm estimates consistently later times than appropriate. The inclusion of a
sleep window variable yields substantial variety in results. A 15-minute window appears best at
determining START while a 5-minute window appears best for END and TIB. Further investigation on
the optimal window length per demographic and condition is required.

Description
Consumption of clean, pathogen-free water is vital in maintaining health. The water infrastructure in Puerto Penasco, Sonora is not sufficient in providing clean water for its residents. Water in this region is being overdrafted, meaning it is distributed from deep wells faster than it can be regenerated, which prevents more wells from being constructed. There is a high need for a cost-efficient solution to the clean water shortage in this impoverished town. The purpose of this study was to determine: (1) how clean drinking water affects health, (2) how contaminated water and water substitutes, such as soda and juices, negatively impact health, and (3) the impact on water consumption by local residents after providing them with a portable filtration system to create clean drinking water in their own homes. Water filters were distributed in two trials to a convenience sample of 45 participants, 27 of whom were successfully contacted for a post-implementation survey. Out of the 27 participants who took the survey, 27% reported that they drank more water after receiving the filter than before, 40% reported drinking less soda after receiving the filter, 63% reported using their filter on a daily basis, 63% believed that drinking clean water is important for their health, and 74% thought that it was difficult for them to obtain clean drinking water before receiving the filter. Providing residents with a filtration system was effective in increasing water consumption and saving residents money on water but did not provide conclusive data, negating the use of soda as a water substitute. This was an effective small-scale solution to a much larger problem that may be beneficial in other similarly impoverished communities.
