Glucosamine and chondroitin supplements, taken individually or in combination, are touted as a way to relieve joint pain from arthritis –– and even to prevent it in the first place. Are they effective?

Research from Denmark found an association between the use of hormonal birth control and an increased likelihood of depression. While the risk of depression among women using hormonal forms of birth control was clearly increased, the overall number of women affected was small and was found to be highest in women under 20.

Research shows that lowering cholesterol using a variety of approaches–including medications and diet–can lower the chances of having a cardiovascular event, including a heart attack. For people at high risk for a heart attack, cholesterol-lowering statins are usually the first-line treatment. For people who can’t take statins, other drugs may help.

The belief that women should avoid exercise or athletics during their menstrual periods, because it can affect performance or increase the risk of injury, is not necessarily true.

It’s especially important for children to get flu shots, both because the flu can hit the young with particular severity, and because of the potential to pass the illness to others.

Teens don’t exercise enough, and with a third of U.S. adults classified as obese, it’s important that exercise is encouraged in children and teens. Starting healthy habits when they’re young keeps kids healthy into adulthood. Studies show that obese adults rarely lose the weight, so it’s better to keep the weight off in the first place.

A study questions whether CPAP helps to slow the progression of coronary artery disease in those who already have it, but use of the device has still been shown to have quality of life and other health benefits in those with sleep apnea.

A study suggests that a new approach to baby-led weaning is safe and has some benefits. With parent supervision, babies can feed themselves solids without a spoon — foods that they can pick up and get into their mouths, but that are also low risk for choking. Benefits of this approach include babies starting solids when they’re ready rather than when parents are ready and babies learn early to be in charge of what and how much they eat.
