Research Proposal Obesity in USA

ResearchProposal: Obesity in USA

Theissue of obesity is not only a health concern, but a social andeconomic concern in the United States (Dube et al., 2010). Studieshave shown that, obesity prevalence has been on the rise over theyears. Data from NHANES also proves the same.


Thecurrent study seeks to establish the latest trend in obesity in theUnited States. This is in consideration to age, gender and ethnicity.Hedley et al. (2004) Ogden et al. (2006) and Ogden et al. (2014) intheir separate studies at different times established that, obesityrate has not decreased even with all the knowledge available onstaying healthy and the dangers of obesity. Lifestyle change has beencited as one of the contributing factors of obesity among the U.Schildren (Anderson &amp Whitaker, 2010). Bailey (2006) argues thatthere is a great connection between obesity and ethnicity. Thisresearch seeks to establish on this relationship as well as on genderand age.


Researchhypothesis is important in guiding the researcher through theresearch process. The study’s hypotheses include:

H1,African Americans are at greater risk of obesity than any otherethnic group in the U.S

H2,the youth are at an increased risk of obesity than children and theelderly

H3,Male are generally affected by obesity more than female

Significanceof the Study

Successfulaccomplishment of this study will be significant as it will provideup to date information regarding obesity prevalence across the U.Spopulace in terms of age, gender and ethnicity. This will be usefulfor stakeholders including individuals, institutions bothgovernmental and non-governmental to come up with an approach to curband manage the problem. With some contradicting information fromauthors such as Oliver (2006) who term the issue of obesity as afuss, the current study will be important in disproving such claims.The use of current data from NHANES and inclusion of the differentgroups will be significant in management of obesity.


Toachieve the objectives of this research, it will be important tocollect relevant data that will later be analyzed. Secondary datawill be the main data that will be used in this study. Secondary datais data obtained from other sources other than from participants suchas databases. The type of data that will be used in this study isquantitative data. Data will be sourced from NHANES which is mainlysecondary data. The NHANES shows that obesity cases in the UnitedStates are in the rise as compared to overweight cases. The currentstudy will collect data regarding obesity and overweight usingpercentages and prevalence rates given in NHANES database. The studywill be concerned in three main groups of people including children,adolescents and adults. Children will comprise of those between ages5 to 10, adolescents of ages 11 to 19 and adults category of ages20-70. The participants will be included on the basis of their bodymass index (BMI) as indicated in NHANES database. Besides age, thecollected data will engage people of different genders andethnicities.


Accordingto Parahoo (2006), the research design selected for a study should bethe most suitable so as to realize the objectives. In order to answerthe research question, the study will utilize both qualitative andquantitative research design, to describe the prevalence of obesityamong the different age groups, ethnicities and gender. Quantitativeresearch provided quantifiable information such as percentages todescribe an issue. On the other hand, qualitative approach helps indescribing the life experiences and giving the meaning (Burnsand Grove, 2009).By using qualitative design, the researcher is able to explore thebehavior pattern of participants, their feelings, perspectives andin-depth experiences.


Thedata collected for this particular study is mainly secondary obtainedfrom the NHANES database.


Asstated by Polit and Beck (2008), data analysis is aimed atorganizing, providing a structure to, and also elicit meaning of thedata collected. Data analysis will involve simple quantitative dataanalysis, including percentages and standard deviation.


Themost basic ethic attributed to data collection method selected forthis study is confidentiality. The confidentiality of the dataobtained from NHENAS was maintained throughout the study. No personaldata was published in the study including the names, residentialaddress and any other information that could lead to identificationof an individual. This is consistent with what Clough &amp Nutbrown(2007) recommends.

Inaddition, consent for the study will be sought from the universityand other relevant authorities including local and state governments.


Basedon the intentions of this study, both qualitative and quantitativedesign are appropriate in reaching the conclusion for this research.Using a mix of this methodology, the research will be able to obtainan understanding of the trend of this case study. According to Ely,Anzul, Friedman, Garner &amp Steinmetz (1991) thedecisions that the researcher has to make for the most suitablemethodology and approaches to be used ought to account for thecomplex reality of the study. Besides, it unavoidably links into theway we construct meaning into what surrounds us in an attempt tomaking sense of what is happening. Thus, this affirms the necessityof the adopted methodology.

Whythis data directly addresses the health issue

Theobtained data is important in analyzing the issue of obesity in theUnited States. The use of three groups of participants i.e. children,adolescents, and adults as well as inclusion of different ages,ethnicities and gender will help identify the most vulnerable groupsin terms of age, gender and ethnicity. This data will helpstakeholders including parents, individuals, organizations and thegovernment at large to come up with a comprehensive approach to theissue of obesity in the country. The data will also be able tocompare with previous studies that have explored this issue.

Themethods you will use to analyze the data

Sincethe collected data is mainly quantitative, both quantitative andqualitative data analysis methods will be used to analyze data.Simple statistical procedures including standard deviation andpercentages will be employed to show the prevalence of obesity amongthe three groups of children, adults and adolescents. In addition,they will be useful in defining the variation in obesity among thedifferent age groups, ethnicities and gender. In addition,qualitative data analysis methods including content analysis will beused to help give meaning to the data. This will help in establishingwhat seems to be the main cause of the issue of obesity amongAmericans. The use of both qualitative data and quantitative datafrom participants require a combination of the two methods of dataanalysis in order to understand this social phenomenon.
