Research Article Review Intro to Graduate Research/ Cameron University June 15, 2010 Summary of Article This study examined obesity in the school systems and the factors of the trial were food consumption, wellness activities, and stress management. Sixteen schools were chosen for the study, eight control, and eight intervention. At the schools only the staff were measured and took part in the study such as teachers, administrators, teacher aides, and others.
The study was testing two hypotheses the first one was that that employees involved in the intervention schools would be more likely to significantly lose weight (lower BMI and waist-hip ratio) than individuals in the control schools and the second hypothesis concerns that people in the intervention schools would be significantly more likely to change diet and physical activity behaviors than individuals at control schools.
The instruments used in this study were a calibrated electronic scale, a stadiometer height board to help calculate body mass index (BMI), cloth tape measure to measure waist to hip ratio, and International Physical Activity Questionnaire (IPAQ) Short Form to measure and report time spent in sedentary activity, moderately vigorous activity, vigorous activity, and walking in the prior seven days. The study concluded there were differences in the control and intervention schools but they were not significant.
The intervention schools only lost an average of . 82 pounds per person while the control schools gained 2. 45 pounds per person during the two year study. Reflection of Article I found this article to be interesting because it studied obesity in schools not with the students but with the faculty and staff. I liked how they looked at more than just how much a person weighed and more at their lifestyle by using the IPAQ form which brought an instrument that brought another degree into the study.
I also liked how long the study took which was a over a two year period from 2005 to 2007 because it showed they were studying the long term effect and way a person lived which cut out issues of short term gain and loses with the test subjects. The way that they picked the schools for the control and intervention groups were randomized which was a good thing because it showed no bias. The schools that were part of the intervention schools did receive incentives such as grants and so forth but it just motivated the schools to take part in the study.
Overall I thought it was a great study, I think even though it took a different aspect of the school with the faculty and staff since they are the role models for the kids I rather see more money put into the students losing weight since they are the future and need to be educated. I just feel if you want to benefit children you have to study both the students and teachers, then evaluate them both and then build a health enrichment program to help get rid of the trend of sedentary lifestyle of being overweight and obese.
Relations of Concepts to Articles This study is an example of quantitative research because it compares and correlates two factors in both of the hypotheses. The hypotheses are (1) “individuals employed at school worksites randomly assigned to be likely to lose weight (as evidence by reduction in BMI and waist-hip ratio) than individuals employed at comparable control worksites; and (2) individuals in intervention schools would be significantly more like to change diets and physical activity behavior than individuals at control worksites. The independent variables in both hypotheses are the factors that is take to lose weight dieting, physical activity, intervention program, and the dependent variable in both hypotheses are the measure of losing weight measured by BMI and waist-hip ratio and the extent of dieting and increase in physical activity for the second hypothesis. They idea of both hypotheses is to try to help promote a healthy lifestyle so that the faculty can be better role models for the students to become healthier.
When it came to sampling in this study it was a randomized controlled trial which took place in 2005 to 2007. The school sites were randomized and they picked sixteen elementary schools in two geographic areas of Los Angeles, California. The schools were either given conditions of being a control or intervention school that they had to follow, and not school boards or sites were contacted prior to full approval from the university and school district review boards.
By reviewing this article seeing how they used the anthropometric measures, the questionnaire, and showing me the variables that were tested in it, it has provided me the knowledge of the instruments that can be used, the importance of having healthy people, employees, and community and to surround young people with positive and healthy role models in their lives.
It has opened my eyes to the type of research that I want to pursue in doing and reviewing for future works so I am able to impact my students and community in a positive way.
