Abstract & Introduction • Obesity Facts: • More than 1/3 of college students have an obese BMI(8) • Obesity is the 2nd leading cause of preventable death(13) • Healthy weight loss consists of 1 to 2 pounds in a week(2) • Why did I chose this study? • My BMI classifies me as obese • Need for a cheap, healthy way to lose weight • Large pop and coffee consumption • Long-term effects on obesity: • Increased blood pressure, elevated blood glucose, potential to foster dehydration • Most effects are irreversible(2)
Problem • Research on college students and their consumption of caffeine • Effects of caffeine • Positive: increased attention, increase emotional state, endurance, and physical performance(6) • Negative: Increased blood pressure, elevated blood glucose, potential to foster dehydration (2) • Is there a link between beverage consumption and overall attitude or disposition? • What about a link to weight or sleep?
Helping Organization • Indiana University Health North Hospital • Carmel, Indiana • Mission Statement: • “To improve the health of our communities, support the education commitment/efforts of IU Health, nurture the individual spirit, and celebrate the experiences of life.” • Bariatric and Medical Weight Loss program • American Society for Metabolic and Bariatric Surgery (ASMBS) Bariatric Surgery Center of Excellence • Programs available: • Surgical options • Non-surgical options • Meal planning, exercise, cooking classes, etc
Methods H1: There is a negative mean difference between a person’s weight during the pretest and posttest intervention. H2: There is a relationship between the day of the week and how much water was consumed. H3: There is a significant relationship between a person’s attitude during the pretest and posttest intervention. • Measurement
Discussion • Expected findings • Difference in weight post intervention was not large • Unexpected that it’d be a statistically significant difference • Surprise findings • Lack of significant difference in mood pre- and post- • This was both my personal bias and due to feelings of more stress during pre-test • No significant relationship between day of the week and beverage consumption • Very set schedule would have seemed to lead to different results • Results could have been significantly different if food intake was controlled
Limitations &Implications • Learning curve of SPSS Statistical software • Intervention only run on one participant • No way to achieve saturation of a sample that reflects the population with one person • No measurement of other intakes • Could have measured food, meds, etc • No account for perceived stress • End of the study had significantly less amount of stress with spring break • No specificity about water intake post intervention • Study was originally about pop intake • Did you know there’s caffeine in chocolate, ice cream, pain relievers, energy waters, and DECAF COFFEE
