Obesity and Type II Diabetes in Youth Are weight management programs effective for reducing the risk of type II diabetes in children ages 5-19? By: Kaitlin Deason And Confidential Group Members FCS 682 . Fall 2011
Research Question Are weight management programs effective in reducing T2DM in children ages 5-19?
Review • Based on current literature • Obesity is associated with the development of T2DM • Obesity affects some communities more than other • Obesity shown to increase both impaired glucose tolerance and insulin insensitivity, which are definite precursors for T2DM. • Lifestyle changes including increased physical activity and weight loss were shown to reverse, delay, and or prevent T2DM in children.
Review Cont. • Currently many programs aimed at reducing childhood obesity, and thereby T2DM. • According to number of children continuing to be diagnosed with T2DM that not enough is being done. • Still a huge need for additional widespread, population targeting, successful, weight management programs that incorporate a variety of healthy lifestyle factors in combination with education in order to prevent and reduce the number of children with type II diabetes in the United States.
Review Cont. • Approximately 16.9% of children and adolescence are obese • The prevalence of childhood T2DM ranges from .19 - 49.4 out of every 1000 • Factors contributing to childhood obesity • Obesity, sedentary lifestyles, family history, high-risk ethnicity groups, and insulin resistance • Obese children are at risk for T2DM • retinopathy, neuropathy, and cardiovascular and renal disease • 40% of children who are obese at age 7 become obese adolescents, and 75% of adolescents who are obese become obese adults
hypothesis • The purpose is to determine the effects of an afterschool exercise program on weight loss and concurrent reduction in risk of type II Diabetes Mellitus • Hypothesis: An afterschool program with an exercise component will improve weight loss outcomes in children, and thus result in a lower risk of developing T2DM
Design • The study has Pre-test, Post-test, True Experimental research design • Participants: randomly assigned using Simple Random Sampling to either a treatment or control group R O X O R O O
Sampling • Population: Participants from elementary schools (K-6) • Stratified Random Sampling • Subgroups: African Americans, Latinos, and Caucasians • Childhood obesity is more prevalent in minority groups such as African Americans and Latinos
Procedure and Research material • Written consent will be obtained • All collected data will be confidential • Trained medical staff will perform clinical examination • Trained staff will collect Height, Weight, and waist circumference using calibrated instruments • Body mass index (BMI) will be calculated • Blood sampling will be performed in fasting status • Blood samples will be analyzed for triglycerides, LDL and HDL cholesterol, fasting glucose, and insulin
Variables • Dependent variables: BMI and Waist circumference: ratio continuous variables • Independent variable: having or not having the organized physical activity
Statistical Analysis • Goal: Compare the mean of anthropometric measurement in the control group and the treatment group • t-test measures the tendency of relationship between the 35-40 minutes of organized exercises and BMI/waist circumference measurement in elementary school children • control and treatment groups have homogeneity of variance • t-test is robust and is the inferential statistics • 2used to determine the magnitude of the difference between organized exercises and anthropometric measurements • Cohen’s effect
Conclusion • Hypothesis: An afterschool exercise program on weight loss and concurrent reduction in risk of type II Diabetes Mellitus • Research design: Pre-test, Post-test, True Experimental • Sampling: Simple Random Sampling • Population: Participants from elementary schools (K-6) • Statistical method: t-test
