A total of 150 participants are selected for a study of risk factors for cardiovascular disease. At baseline (study start), 24 are classified as hypertensive. At 1 year, an additional 12 have developed hypertension, and at 2 years another 8 have developed hypertension. What is the prevalence of hypertension at 2 years in the study? What is the 2 year cumulative incidence of hypertensions?
Homework Answers
Period prevalence refers to prevalence measured over an interval of time. It is the proportion of persons with a particular disease or attribute at any time during the interval.
Prevalence of hypertension at 2 years in study = (24 + 12 + 8) / 150 = 44/150 = 0.2933 i.e. 29.33%
2 year cumulative incidence of hypertensions = 24 + 12 + 8 = 44

In a cohort study exploring the relationship between acute myocardial infarction and hypertension, the study investigators enrolled 10,000 people with hypertension and 10,000 people without hypertension. All study participants were healthy and had no previous history of myocardial infarction. The investigators followed the subjects until the subject developed a MI or 15 years elapsed, whichever came first. 180 of the subjects with hypertension and 30 subjects without hypertension developed MI during the course of the study. If no MI developed...

An investigator initiated a clinic-based cohort study in 1997 to investigate factors associated with HIV seroconversion in a population-based sample of n=489 adults between 35-60 years old. The study was launched on January 1, 1997 and participants were asked to return for follow-up visits on a yearly basis. - at the baseline visit, n=43 participants tested HIV-seropositive among the sample of 489. - at the first follow-up visit, beginning in January 1, 1998, among those who were HIV-seronegative at baseline,...

What was the cumulative incidence of HIV among study participants in January 2003? What was the cumulative incidence of HIV among study participants in January 2003? In January 2000, 5000 men and women aged 18-30 years were recruited from a semi-urban area near Durban (South Africa) and assessed for human immunodeficiency virus (HIV). Participants who did not test positive for HIV, at baseline in 2000, were followed-up and assessed again 3 years later in January 2003 (only those who previously...
