Problem
A. Read the title for each study and then identify if the study is experimental, quasi-experimental or descriptive AND justify why. "Cardiometabolic Risk Factors Among 1.3 Million Adults with Overweight or Obesity, but Not Diabetes, in 10 Geographically Diverse Regions of the United States, 2012 - 2013. "
B. Read the title for each study and then identify if the study is experimental, quasi-experimental or descriptive AND justify why. Identification of Patients with Diabetes Who Benefit Most From a Health Coaching Program in Chronic Disease Management. (Participants were randomly assigned to groups.)
C. Read the title for each study and then identify if the study is experimental, quasi-experimental or descriptive AND justify why. Prevalence of Mindfulness Practices in the U.S. Workforce: National Health Interview Survey.
D. Read the title for each study and then identify if the study is experimental, quasi-experimental or descriptive AND justify why. A Cooking Intervention to Increase Vegetable Consumption by Parents with Children Enrolled in an Early Head Start Home Visiting Program. (Convenience sample.)
E. Read the title for each study and then identify if the study is experimental, quasi-experimental or descriptive AND justify why. A Physical Activity Program and Changes in Body Mass Index in Middle School Physical Activity Classes with a Large American Indian Population, Oklahoma.
F. Read the title for each study and then identify if the study is experimental, quasi-experimental or descriptive AND justify why. Walking to Work: Trends in the United States, 2005 - 2014.
G. If the study was a predictive correlational design, identify which type of regression was used. Researchers examined the association between food insecurity in college freshmen and their health behaviors (such as consuming breakfast at least 4 times/week or eating at least 5 fruits and vegetables a day). The odds ratio of consuming breakfast at least 4 times/week for food insecure freshmen was 0.43 compared to food secure freshmen.
H. If the study was a predictive correlational design, identify which type of regression was used. This study included over 7,000 participants with hyperinsulinemia, and without diabetes or a history of cancer. The researchers followed them for 11 years to see who was diagnosed with cancer. Cancer mortality was significantly higher in those with hyperinsulinemia than in those without hyperinsulinemia (adjusted HR 2.45).
I. If the study was a predictive correlational design, identify which type of regression was used. This study looked at associations between intakes of alcohol and high calorie beverages in midlife American women and their cardiometabolic risk factors. Over 12 years of follow-up, high calorie beverage consumption was associated with metabolic syndrome in midlife women.
J. If the study was a predictive correlational design, identify which type of regression was used. Researchers looked at associations between self-reported sleep duration (age and gender were covariates) and sugared caffeinated soda consumption (in calories) in American adults. Participants who slept at least 7 hours/night were the reference group. Participants who slept the least were more likely to drink more sugared caffeinated drinks.
K. If the study was a predictive correlational design, identify which type of regression was used. Researchers recruited 240 children with asthma and 240 controls, in a study looking at differences in the diets of children with and without asthma symptoms. Parents of the cases were interviewed about their children's eating habits before diagnosis. Parents of the controls were also interviewed about their children's eating habits. Eating a high number of desserts appeared to increase risk of developing asthma, while high vegetable intake appeared to be protective.
L. Read the following original research article and answer all questions below. Freedman, M.R., & Connors, R. 2011. Point-of-Purchase Nutrition Information Influences Food-Purchasing Behaviors of College Students: A Pilot Study. Journal of the American Dietetic Association, 111, S42-S46.
