1. Sleep Duration has Little Effect on Caloric and Macronutrient Intake in Messiah College Students Meghan Brady, Jennifer Myer, and Tessa Smith Department of Nutrition and Dietetics, Messiah College, Mechanicsburg PA 17055 http://fc05.deviantart.net/fs70/i/2011/231/e/5/burger_png_by_dbszabo1-d473bva.png http://blog.txu.com/wp-content/uploads/2012/09/AlarmClock.jpg • Results • Multivariate 2-way ANOVA between %recommended, %protein, and % carb against sleep was run with a poor significance of P = 0.471, showing no correlation between the variables. • %fat was excluded from our analyses because it too highly correlated with %recommended and %protein and made • the analysis intractable. • Removing the % fat did not however remove the information from the model because % fat was part of the other variables. • Multivariate 2-way ANOVA examining %carb and %fat against sleep yielded the most notable results; shorter sleep duration was associated with higher carbohydrate and fat intake the following day (P = 0.07). • Due to the small sample size for this research, the significance of this last test needs be seen as coincidental since the overall test was insignificant. 200 × 200 - helpmedrronda.com • Introduction • Medical experts started to notice an obesity epidemic in America around the same time that shorter sleep duration was on the rise. • Lack of sleep has been suggested to affect energy balance and result in weight gain by three main pathways: up-regulation of appetite, more time to eat, and/or decreased energy expenditure. • Since this discovery, research has attempted to draw correlations between sleep duration and subsequent diet intake, however, the college population has been overlooked in all of these studies. • Gaining a better understanding of the trends within this group would be valuable to improving the health of future generations. • Methods • In this observational study, researchers educated subjects on how to record food, sleep, and activity data. • Age, height and weight were collected from all participants. • Subjects were asked to record four consecutive days of their diet, activity, and amount of sleep obtained. • Food Processor was used to analyze food data for caloric and macronutrient intake for each subject for all four days and data was then transferred into an Excel Spreadsheet. • Researchers met with a statistician to perform data analysis using Minitab Statistical Software. • Several 2-way multivariate ANOVA tests were implemented to find correlations between sleep duration and caloric and macronutrient intake. Research Question and Hypothesis • Research Purpose: The purpose of this study is to document the affect that sleep duration has on diet in the Messiah College population. • Hypotheses: • Messiah College students that sleep less than 7 hours a night will have an increased caloric intake compared to students that obtain 7 or more hours of sleep. • Students who sleep less than 7 hours per night have higher proportions of fat and carbohydrates in their diet compared to students who sleep 7 or more hours per night. c. • Conclusion • In the college population sleep duration was not found to affect the next days’ diet intake. • Insignificant results may be due to low subject participation, inaccurate estimation of portion size/forgetting to record food intake, incorrect transfer of diet data into Food Processor Software, and/or incorrect transferring of data to Excel spreadsheet. • Because one of the tests found a correlation that could be potentially significant with a larger subject group (%carbohydrate and %fat=sleep), future research should be conducted to assess if a significant correlation could exist between sleep duration and %carbohydrate and %fat intake. a. b. . • Subjects • 16 Messiah College Students (3 men) ages 18-25 • Recruitment was through email, flyers, and word of mouth • Had to be able to read and write in English • Excluded those with a diagnosed sleep disorder or a medical condition that would drastically affect food selection (for example: celiac disease, diabetes) http://blogmedia.eventbrite.com/wp-content/uploads/sleep-on-books-1.10.12.jpg

Poster Size: 31 inches x 41 inches (this template is already 31 x 41”… check Page Setup) • Font Recommendations: • A poster should be easily readable from 3-4 feet away. • A 72 point font = approx. 1 inch high • So here are some rough guidelines: • Title: 90-120 point • Authors: 64-84 point • Affiliations (if necessary): 42-56 point • Section Headings (Introduction, Methods, Results, etc.): 48-52 point • Text in the introduction, methods, captions, etc.: Minimum of 28 point, but 32 ptto 40 pt is more readable • Note: remove “average” in research question and hypotheses when talking about sleep duration, we did not average their sleep
