An epidemiologic study in Belgium examined the relationship between daily sunlight exposure and the development of cataracts in 8,000 individuals. The results of the study were as follows: OR = 1.9 (95% CI = 1.2 to 4.6). After controlling for vitamin E intake, a possible protective factor, the ORMH was 3.6 (95% CI = 1.3 to 5.1). Failure to control for Viramin E led to which of the following in the above study? A. Negative Confounding B. Selection Bias C....

A recent study of the effects of income on demand for health care evaluated the effects of job changes, including job loss, unemployment compensation, and salary increases on the demand for healthcare. The study found that when income dropped by 2%, the demand for health services dropped 0.5%. Another recent study analyzed these effects by comparing the demand for health care across families at different income levels in the United States. The second study found that among families with annual...

A recent study examined the effect of diet cola consumption on calcium levels in women. A sample of 16 healthy women aged 18 – 40 were randomly assigned to drink 24 ounces of either diet cola or water. Their urine was collected for three hours after ingestion of the beverage and calcium excretion (in mg) was measured. The researchers were investigating whether diet cola leaches calcium out of the system, which would increase the amount of calcium in the urine...

A research study examined the effects of meditation on quality of sleep. Fifty individuals were asked how many nights, on average, they lost sleep at the beginning of the study. Then all fifty individuals were placed into a meditation intervention every day for three months. At the end of the three months, the same fifty individuals were asked how many sleepless nights they had on average. The mean difference between the before and after intervention groups was 5.6 nights, with...

A study that evaluated the effects of a reduction in exposure to traffic-related air pollutants compared respiratory symptoms of 281 residents of an area with congested streets with 168 residents in a similar area where the congestion was removed because a bypass was constructed. The symptoms of the residents were evaluated at baseline and again a year after the bypass was completed. For the residents of the congested streets, 16 reported that their symptoms of wheezing improved between baseline and...
