To determine what lifestyle factors might lead to high blood pressure, researchers recruited two groups of subjects, half with high blood pressure and half without. They asked each patient many questions about their past diet and exercise habits. This is a :
Case-controls study
Researchers observed a large group of subjects for many years, tracked how many of them died, and what they died of. Many of the subjects smoked. This showed that smoking caused a lot of deaths. This was a:
Cohort Study
Case-Control Study

A random sample of medical students was given a single survey to determine how many hours of sleep they averaged at night. This is a:
Cross-sectional study
A snapshot of the American healthcare scene presents a mixed message. Some medical conditions have improved, while some have regressed. For example: A) Obesity has decreased since the year 2000 due to increased fitness centers. B) The number of people with diabetes is predicted to decrease by 2050 due to an increased number of sugar-free treats. C) Heart disease is no longer a problem in the US, due to technological advances. D) Many life-threatening infections are no longer deadly due to the invention of antibiotics.
D) Many life-threatening infections are no longer deadly due to the invention of antibiotics.

C) Performed a randomized controlled trial and concluded that heart disease is the leading cause of mortality in the United States. D) Performed a review and meta-analysis and concluded that smoking remains the leading cause of mortality in the United States.
D) Performed a review and meta-analysis and concluded that smoking remains the leading cause of mortality in the United States.
Scientific studies and articles frequently report their findings of risk or benefit in percentages as "relative" effects rather than absolute. This can be a problem because: A) Readers cannot understand absolute effects. B) Presenting risks and benefits as "relative" is more accurate than presenting findings as "absolute". C) The findings only pertain to people the subjects are related to, or their "relatives." D) Presenting risks and benefits as relative can make effects seem bigger than they actually are.
D) Presenting risks and benefits as relative can make effects seem bigger than they actually are.
In the Lifestyle Medicine approach to health care: A) the responsibility for improvement is on the clinician. B) the provider treats individual risk factors with medications.

Researchers gave daily fish oil tablets to school children for one year, to see if their academic performance would improve due to the fish oil. At the end of the year, many of the children who got fish oil did improve their academic performance on a test, but no other group was tested. This is an example of a scientific error called:
Failing to have a control group
Cohort Study
Follows a group of people to track risk factors and outcomes over time Exposed vs. Non-Exposed
A study showed that in premature infants with severe colon infections, giving probiotic tablets by mouth helped their colon heal and slowed diarrhea. A blogger is advertising his probiotics and using this study as a reference, claiming that the pills heal damaged colons in adults. This is an example of a common scientific error called:
Generalizing to a different population than was studied
Qualitative Studies
Helps us understand, for instance, what it is like for people to live with a certain disease. Unlike other kinds of research, qualitative research does not rely on numbers and data.
Blinding
Methods of preventing individuals, healthcare providers, and those assessing outcome in a study from knowing whether the participant is in the experimental or control group
A study finds a correlation between men in Greece who smoke and also consume a large number of olives daily, who later develop lung cancer. The media published a headline stating that "olives cause lung cancer." This is an example of of a scientific error called:
Mistaking correlation for causation
Tertiary Prevention
Patient has already suffered an event or already has received a diagnosis, and they are trying to prevent any consequences of the disease or even reverse it
Secondary Prevention
Patient has risk factors for a disease and wants to avoid receiving a diagnosis
Primary Prevention
Patient is healthy and wants to stay that way
