Coffee may not affect blood pressure in women, reported an article in Mobile Register, November 9, 2005. This article was based on a study reported by the Journal of the American Medical Association (2005) that followed 155,594 mostly white female nurses, age 55 on the average, who took part in two long running health studies. The participants were questioned periodically about their diets and health and followed for over 12 years. a) Is this an observational study or an experiment? b) Caffeine is a well-known beverage in both coffee and cola and has been shown to cause short-term increases in blood pressure. The article reported that drinking coffee doesn’t seem to cause long-term high blood pressure. Can such a cause-and-effect conclusion be drawn from this study? Justify your response.

A group of 156 heart attack patients who were regular smokers up to the time of their heart attacks were followed for ten years. Among them, 75 patients continued to smoke after their heart attacks and 81 quit after their heart attacks. Of the 75 patients that continued smoking, 27 had a second heart attack during the ten years of follow-up, and of the patients who quit, 14 had a second heart attack during the 10 years of follow-up. What is the risk ratio for the association between continued smoking and second heart attack? Round to two decimal places
Marilyn Winkleby and her research associates (1992) state that "one of the strongest and most consistent predictors of a person's morbidity and mortality experience is This finding persists across all diseases with few exceptions, continues throughout the entire lifespan, and extends across numerous risk factors for disease." the number of days spent in a hospital that person's socioeconomic status (SES) how close to a hospital a person lives how frequent a person sees a medical professional
A study was conducted by the NIH (National Institute for Health) with a large population that examined smoking and the occurrence of lung cancer. In the duration of the study period, 1,800 smokers developed lung cancer. In the same period, 200 nonsmokers developed lung cancer. There were 241,800 current smokers and 478,000 nonsmokers in the total study population. 1.what type study ?

A researcher would like to evaluate the claim that a new drug, "Acne Buster" can help individuals eliminate acne. Participants were randomly assigned to 2 different groups. One group of participants is given the Acne Buster pill daily and the other group is given a placebo (sugar pill). The researcher records the number of acne outbreaks each individual experiences during the 30-day trial run. What type of study (correlational, longitudinal, experimental, naturalistic observation) is this?

A case-control study is conducted to estimate the association between sedentary lifestyle and stroke. Researchers enroll 100 patients who had a stroke in the past year and 400 patients who have never had a stroke. Researchers conclude that the prevalence of stroke in the past year in the population is 20%. This conclusion is: Correct Incorrect because prevalence cannot be estimated from a case-control study Incorrect because the prevalence is 25%
You enrolled 6,500 men in 2005 and followed them for 10 years. Liver cancer is your outcome; none of the men had liver cancer at the start of the study. Of those men who drank alcohol daily (n=2,000) starting in 1990, 50 were diagnosed with liver cancer during the 10-year period. Of those who abstained from alcohol in 2005, 50 had liver cancer diagnosed during the 10-year period. Nobody died or was lost to follow up during the study period.

A case-control study was conducted to examine the risk factors for HPV infection among OB/GYN clinic patients. The researcher hypothesized that women with HPV cases will report a greater number of multiple sexual partners compared to controls. The existing literature indicates that cases (women with HPV infection) without delay tend to recall and report accurate information about their sexual partners. On the other hand, recall and report of accurate information about multiple sexual partners among controls may not be as clear. (1) Define the direction and the type of biases in the following examples. Choose only one answer for each question. This is study is liable to the following bias: a) Confounding b) Selection Bias c) Information Bias (2) The relationship between HPV infection and the number of sexual partners is likely to be:a) Can go either direction b) Under-estimated c) Over-stimated (3) The following are examples of bias except: a) Confounding…
