A quantitative methodology outline

1. Identified target population

· The target population of this research is the men and women with obesity in the Southern Cone of America.

· The targeted towns include Marcos Paz and Bariloche in Argentina, the Uruguays Pando-Barros Blancos and Temuco city in Chile.

2. Your specific sample of participants:

· What/who will comprise your sample(s)?

i. The sampled population will be people with records of obese.

ii. The sample size comprises 7,524 obese people (3165 men and 4359 women) within the age bracket of between 35 and 74 years old.

· Where will you find them?

i. The sample population will be sampled from the towns of Southern Cone of America.

ii. These includes the Marcos Paz and Bariloche in Argentina, the Uruguays Pando-Barros Blancos and Temuco city in Chile.

· How large will your sample(s) be?

i. The sample size will be 10,254 randomly selected individuals.

· What is your rationale for these decisions?

i. The larger the sample the better to increase the degree of confidence and reduce errors due to the respondents behavior.

ii. The number will cater for those who will refuse to take part, those who will not complete the survey, and those who will not complete clinical examinations (Ormston et al., 2014).

3. Method for getting the data from the sample:

· How will you recruit the subjects?

i. Subjects will be recruited randomly in the towns identified after seeking the participants consent (Meadows, 2003).

ii. Random sampling will not observe gender stratification (Meadows, 2003).

· What general process will you use to collect the data? (e.g., where will you collect it?  Who will collect it?  Etc.  What is the process you and the participant will go through so you can get the data, in other words?)

i. Data will be collected using a multiple of data collection tools.

ii. There shall be home visits entailing surveys to collect demographic characteristics of the participant, healthcare access, (Cardiovascular diseases) CVD and risk factors personal history, their physical activity and Dietary History.

iii. There shall also be clinical visits to collect Anthropometric measurements like blood pressure, body weight, waist circumference and height (Meadows, 2003).

· What specific independent and dependent variables will you be studying, and how specifically will you measure those variables?

i. The independent variables in this study will include the race (black American and the whites) and CVD risk factors.

ii. The dependent variables will include the overweight, obesity and central obesity in the Southern Cone of Latin America.

iii. Dependent variables will be measured clinically using set of anthropometric protocols and techniques. For instance, BP measured using a standard mercury or aneroid sphygmomanometer, Body weight using standing scales and body height without shoes using a wall-mounted stadiometer and waist circumference measured in centimeters above the navel during minimal respiration (Meadows, 2003).

· What comparison groups will you have, if any?

i. Will compare the cardiovascular diseases of the whites and the black Americans, and other races like the Hispanic.

ii. Male and female obese, overweight and central obesity comparison will be done

· What instruments or measurements will you use to get the data?

i. The questionnaires will be used to obtain participants demographic and personal characteristics (Ormston et al., 2014).

ii. Anthropometric measurements will be done using clinically approved protocols and techniques.

iii. The overnight fasting blood creatinine, lipids and glucose levels will be measured

iv. Again, the total and HDL-cholesterol and triglycerides will be measured too.

· How did you decide on these particular groups, instruments or measurements?

i. The decision to use these groups was derived from the theory of prevalence of obesity among whites than the blacks and minorities in America.

ii. The use of protocols and set techniques for Anthropometric measurements were chosen for clinical procedures (Meadows, 2003).

iii. Structured questionnaires were used to collect demographic characteristics because of the nature of data (qualitative) inclusivity of data collected and validity of the data collected (Ormston et al., 2014).

4. Ethical Considerations and Steps for your proposed study, based on our prior weeks' materials

· The participants are required to first agree on a written consent for participation.

· Participants’ personal information will be confidential and private from third parties.

· Participants anonymity for the sake of research findings

· Information obtained shall be distributed freely (Ormston et al., 2014).
