How to Have a Healthy Day From Morning to Night

We work, we plan, we organize, we go, fueling ourselves on coffee and pure determination. Until, that is, we fall onto the sofa in a stupor. More of us are struggling with energy issues, experts say; they point to the weak economy, which has us working harder and plugging in longer, and the belief that we can have it all (so what if we’re up till midnight making it happen).
“Just like houseplants need water, our energy reserves need regular replenishing,”

What is a case-control study in medical research?

What is a case-control study in medical research?

Markus MacGill

A case-control study is a type of medical research investigation often used to help determine the cause of a disease, particularly when investigating a disease outbreak or a rare condition.

If public health scientists want a relatively quick and easy way to find clues about the cause of, for example, a new disease outbreak, they can compare two groups of people:

• Those who already have the disease – ‘cases’
• Similar people who have not been affected – ‘controls.’

A case-control study is retrospective – the researchers look back at data collected in the past, enabling them to test whether a particular outcome can be linked back to a suspected risk factor. To test for specific causes, the scientists need to formulate a hypothesis about what they think could be behind the outbreak or disease. They then compare how often the group of cases had been exposed to the suspected cause (risk factor), versus how often the controls had been exposed. If the risk factor has a greater prevalence among the cases, then this is some evidence to suggest that it is a cause of the disease.Risk factors could be uncovered by researchers studying the medical and lifestyle histories of the people in each group. A pattern may emerge that links the condition under investigation to certain factors.Case-control research is a central tool used by epidemiologists, who look into the factors that affect the health and illness of populations.Just one risk factor could be investigated for a particular disease outcome. A good example of this is to analyze how many people with lung cancer, versus how many without, have a history of smoking.

You can also find them in some foods and supplements.It’s only been since about the mid-1990s that people have wanted to know more about probiotics and their health benefits. Doctors often suggest them to help with digestive problems. And because of their new found fame, you can find them in everything from yogurt to chocolate.
