Childhood obesity

Childhood obesity
The state of Florida is the fourth most obese state in the U.S for children aged 10 and 17 years whose obesity rate is 36.6% (State of Obesity, 2017). Therefore, the aim of this research is to establish the impact of childhood obesity interventions like physical activity on body mass index (BMI) of study participants aged 10 and 12 years. Childhood obesity has become a significant health and social problem, therefore prioritize heath education and promotion practices can help to build healthy families and communities.
Study participants for this research will be children aged 10 and 12 years from Miami-Dade County, Florida. The inclusion criteria for this study will be any child with a body mass index (BMI) greater than 85th percentile whose parents give consent to participate in the study. Children will be excluded if they were part of an obesity intervention/health promotion program as well as if the participants suffer any chronic medical condition or not obtaining consent from parents to participate. All study participants will come from one school what kind of school? Junior high? in Miami-Dade County since the study interventions will take place at the participant’s local school and family settings. Rationale for the setting? A total of 60 children aged 10 and 12 years will be recruited for this research either in the control group or the test group. In addition, 10 subjects have been added to the sample goal after considering a 10% attrition rate, as some participants may choose to not complete the study (Grove, Burns, & Gray, 2013). Therefore, my target sample size for this study will total 70 children.

Sampling Strategy
The sampling strategy for this research will draw upon purposive sampling which is a nonprobability sampling method and it will allow the researcher to focus on targeted group in line with research hypothesis and research question (Grove, Burns, & Gray, 2013). Moreover, engaging children’s parents and school will allow for childhood obesity interventions such as exercise, healthy diets and healthy lifestyles to be implemented in the test group in collaboration with children’s school and parents.
The BMI of all prospective study will be determined using guidelines provided by Centers for Disease Control and Prevention (CDC). Per CDC (2017), BMI is determined by dividing the weight of each study participant in kilograms by square height measured in meters. All prospective participants whose BMI is in the 85th percentile and over will be grouped together using purposive sampling by the research. The final sample will have 70 study participants whose BMI is in the 85th percentile and over. These will then be divided into control and test group for the purpose of the study.
Research Design
The research design for this study will be quasi-experimental design because it will allow the researcher to collect data from participant’s normal settings. Per Grove, Burns, and Gray (2013), quasi-experimental design allows for research respondents to divided into control and test groups and ensure that pre-tests and post-tests are carried out for all respondents. Therefore, the researcher will be able to collect data from both the control and the test group and use it to test research hypothesis. Furthermore, quasi-experimental design will allow for data to be collected from the same research participants for a period of one year while at the same time facilitating for childhood obesity interventions to be implemented at family and school settings. When you state that you going to collect over the course of a year that means you are changing the parameters of the quasi experimental study. Because you will most likely be following them and doing periodic measurements. What you should think about is conducting this study over a 3 or 6 month period to see if there is an effect on your proposed outcome. Instead of supporting your choice with statements from the textbook, support your choice based on how you will conduct your study.
Research Question
In children aged 10 and 12 years in Miami-Dade County, what are the effects of obesity interventions on a reduction in BMI of overweight and obese children in the intervention group compared with no intervention within a one-year period? There is no point in comparing to a group with no intervention because you are not going to gain anything significant from the data. You measure them before and after and chances are there will not be any change. So you really only have 1 group with a pre and post test method.
