Question 1:Read the following paper, and answer the questions below:Sundquist, K. Qvist, J. Johansson, S. Sundquist, J. “The long-term effect of physicalactivity on incidence of coronary heart disease: a 12-year follow-up study”(a)“What study design does this study employ”? [1 point]-Longitudinal study (b)“Find the methodological aspects mentioned in the paper that convinced youthat is the type of study design, please use dot points” [2 points]-The study participants were recruited in 1988 and 1989 and then followedtill 2000.-The samples were randomly sampled from the population and followedthrough telephone contacts while being studied for approximately 12 years(c)“What justification do the authors give for conducting this study, please usedot points”? [2 points]-The study seeks to understand the relationship between the physicallyactiveness and developing coronary heart diseases.-The author has justified his study by stating that previous studies havefailed to study the association between physical activity and developmentof coronary heart disease among the low socio economic status.-Thus there has been neglect from the research arena in assessing andstudying the social factors which surround the women getting coronaryheart disease(d)“What was the proportion of those who (i) do not do any physical activity (ii)engaged in twice a week vigorous physical activity”? (You are not requiredto report 95% confidence intervals) [2 points]-Almost 9% of the respondents that is 463 do not respond or performphysical exercises.-Approximately 37.8% representing 1958 respondents perform physicalexercise(e)“What is the crude incidence rate of CHD in inactive men and inactivewomen”? [2 points]-the crude incidence rate for inactive men and women is 1 as this is thereference point for the study.(f)“What is the crude relative risk of being non-active versus being “highlyactive” (vigorous physical activity at least twice a week) in men and inwomen”[2 points]-the relative risk of non active participants is 80 while for men and womenhaving atleast 2 physical activity is 60 for women and 35 for men in asample of 5196
