Description
No studies have evaluated the impact of tracking resting energy expenditure (REE) and modifiable health behaviors on gestational weight gain (GWG). In this controlled trial, pregnant women aged >18 years (X=29.8±4.9 years) with a gestational age (GA) <17 weeks were randomized to Breezing™ (N=16) or control (N=12) for 13 weeks.

No studies have evaluated the impact of tracking resting energy expenditure (REE) and modifiable health behaviors on gestational weight gain (GWG). In this controlled trial, pregnant women aged >18 years (X=29.8±4.9 years) with a gestational age (GA) <17 weeks were randomized to Breezing™ (N=16) or control (N=12) for 13 weeks. The Breezing™ group used a real-time metabolism tracker to obtain REE. Anthropometrics, diet, and sleep data were collected every 2 weeks. Rate of GWG was calculated as weight gain divided by total duration. Early (GA weeks 14-21), late (GA weeks 21-28), and overall (GA week 14-28) changes in macronutrients, sleep, and GWG were calculated. Mediation models were constructed using SPSS PROCESS macro using a bootstrap estimation approach with 10,000 samples. The majority of women were non-Hispanic Caucasian (78.6%). A total of 35.7% (n=10), 35.7% (n=10), and 28.6% (n=8) were normal weight, overweight, and obese, respectively, with 83.3% (n=10) and 87.5% (n=14) of the Control and Breezing™ groups gaining above IOM GWG recommendations. At baseline, macronutrient consumption did not differ. Overall (Breezing™ vs. Control; M diff=-349.08±150.77, 95% CI: -660.26 to -37.90, p=0.029) and late (M diff=-379.90±143.89, 95% CI:-676.87 to -82.93, p=0.014) changes in energy consumption significantly differed between the groups. Overall (M diff=-22.45±11.03, 95% CI: -45.20 to 0.31, p=0.053), late (M diff=-23.16±11.23, 95% CI: -46.33 to 0.01, p=0.05), and early (M diff=20.3±10.19, 95% CI: -0.74 to 41.34, p=0.058) changes in protein differed by group. Nocturnal total sleep time differed by study group (Breezing vs. Control; M diff=-32.75, 95% CI: -68.34 to 2.84, p=0.069). There was a 11.5% increase in total REE throughout the study. Early changes in REE (72±211 kcals) were relatively small while late changes (128±294 kcals) nearly doubled. Interestingly, early changes in REE demonstrated a moderate, positive correlation with rates of GWG later in pregnancy (r=0.528, p=0.052), suggesting that REE assessment early in pregnancy may help predict changes in GWG. Changes in macronutrients did not mediate the relationship between the intervention and GWG, nor did sleep mediate relationships between dietary intake and GWG. Future research evaluating REE and dietary composition throughout pregnancy may provide insight for appropriate GWG recommendations.

This body of research sought to explore relationships between cognitive function and physical activity (PA), sedentary behavior (SB), and sleep, independently and in conjunction, in mid-life to older adults with no known cognitive impairment. Aging is associated with cognitive decline, and lifestyle behaviors such as PA, SB, and sleep, may mitigate this decline. First, a systematic review and meta-analysis was conducted to examine the effect of aerobic PA interventions on memory and executive function in sedentary adults. Second, a longitudinal study was conducted to examine the association between SB and odds of incident cognitive impairment, and SB and cognitive decline in older adults. Last, a cross-sectional study was conducted to examine the joint associations between different levels of sleep with levels of PA, and sleep with levels of sedentary time on memory and executive function. This body of research provided evidence to support the association between aerobic PA and improved cognitive function, SB and incident cognitive impairment and cognitive function declines, and the joint association of sleep and different levels of PA and ST on cognitive function by hypertension status.

Through the use of Arizona State University’s Founders Lab, our group of four Barrett, the Honors College Students completed a research thesis regarding the interest of college students in a sleep light technology product. The National Aeronautics and Space Administration (NASA) pioneered a sleep light technology with the ability to regulate melatonin production and circadian rhythm, resulting in an improvement of sleep quality. The technology was originally invented for astronauts to improve their sleep while in space on a spacecraft. Utilizing this technology, our group performed extensive market research with the intention of determining if college students would be interested in purchasing a consumer product incorporating the sleep light technology. We created a brand called Rhythm Illumination and began by building a website and brand guide. Next, we utilized Google Forms to generate responses to a variety of questions regarding current sleep habits, current sleep problems, and whether or not there was interest in a product like this. After determining that college students have room for sleep quality improvement and there is interest in this kind of product, we worked towards our goal of gaining traction for the product. We decided to utilize both Google Analytics results and a Zoom event’s attendance as proof of interest in our product. Google Analytics revealed over one hundred unique users on our Rhythm Illumination website. We also had eleven event attendees. Between these two tools, our team was able to conclude that there is interest among college students for a consumer product utilizing NASA’s sleep light technology.

The purpose of this thesis study was to market a favorable solution to reduce stress levels and improve the quality of sleep for young adults by using a piece of technology developed by NASA. This technology was a lighting system initially designed to help astronauts regulate their circadian rhythms in space, and our goal was to find a suitable market for this type of product. Our team wanted to focus on college students because they often suffer from high anxiety and stress levels, which affects their overall productiveness in study rooms and dorms. After conducting research and interviewing students on the ASU campus, we wanted to market a solution that incorporates the same technology, but is also able to adjust lighting intensity and color. Taking this solution, our group setup demonstration rooms in Noble Library to collect data from students who would be interested in seeing more of this product on campus. Additionally, a Facebook advertisement campaign was launched to promote our website and gain any other feedback. Ultimately, these two methods of outreach proved to be a huge success, and there was a significant amount of interest in this product, validating that there is a potential market.
