It's well known that women fall more often than men, but why is that so? A team of Canadian researchers tackled that question by looking for factors that tend to put women at higher risk than men for spills.

The researchers studied around 15,000 adults ages 65 and older who were enrolled in the Canadian Community Health Survey–Healthy Aging. All the participants were asked if they had suffered a fall serious enough to limit their normal activity. People who answered "yes" were then queried about their lifestyles and medical histories. When the researchers analyzed the answers, they determined that stroke, arthritis, and poor nutrition increased the risk of falls in both men and women. However, different risk factors were linked to falls for women, including being 85 or older, having at least one alcoholic drink a week, taking five or more medications, and having diabetes or osteoporosis. The findings were reported online Feb. 19, 2015, by the American Journal of Epidemiology.

Q. Why do people over 60 lose height? I've lost a few inches over the years. Can this be prevented?

Easy ways to increase activity and cut down on sedentary time.

It's no secret that healthy living can reduce your risk for developing heart disease. But ever wonder how much it may help? Up to 92%, suggests a study published Jan. 6, 2015, in the Journal of the American College of Cardiology. It evaluated health habits of 70,000 young and middle-aged women during a 20-year period. The habits included not smoking; exercising for at least 2.5 hours each week; watching TV for fewer than seven hours a week; consuming a diet rich in vegetables, legumes, and whole grains but low in red meat, refined grains, and sugar; consuming no more than one alcoholic drink daily; and having a body mass index in the normal range. Compared with women who had none of those habits, women with all six reduced their risk of developing heart disease by 92%. Why do those habits provide so much protection against heart disease? "Limiting TV watching frees up time for exercise, and the other activities are known to reduce blood pressure, LDL cholesterol, and blood sugar, which reduce the three major risk factors for heart disease—hypertension, high levels of cholesterol and triglycerides, and diabetes," says Dr. Randall Zusman, a cardiologist and Harvard Medical School associate professor. And even though the study involved young and middle-aged women, Dr. Zusman reminds us that it's never too late to adopt a healthy lifestyle.

Q. I had a mild heart attack a few years ago but am now feeling fine. I'm planning a trip to Colorado. Is it safe for me to hike at high elevations?

A. If you're feeling well and don't have any cardiovascular symptoms, hiking in the Rocky Mountains should probably be fine, though you should check with your cardiologist first. Doctors used to advise people with cardiovascular conditions—even just high blood pressure—not to spend time at high altitudes. But there wasn't much evidence behind that recommendation. Now, there's a general consensus that ascending up to 12,000 feet should be fine for most people with heart disease. Exceptions include people with unstable cardiac disease, heart failure, or severe lung disease, such as pulmonary hypertension.

Hidden causes of shortness of breath can make the problem tricky to treat.

Standing up more throughout the day may help you dodge heart disease and live longer.

Some first-generation diet pills proved risky to the heart. New drugs may have expanded the options for treating obesity.

Here are some steps you can take to reduce your reliance on medication to control symptoms and stay functional.

What's better for you: moderate but prolonged exercise, or a shorter but more intense workout? A recent study in Annals of Internal Medicine found that both levels of exercise will help you lose about the same amount of belly fat if you burn the same number of calories. But only high-intensity exercise helped control blood sugar levels.

In the study, 300 people with abdominal obesity walked and jogged on treadmills at a moderate or high intensity, burning equivalent numbers of calories. The 217 people who stuck through the study for the entire six months lost on average 1.75 inches from their waistlines—about 5% to 6% of body weight. It made no difference whether they huffed through the higher-intensity workout or the more moderate regimen.
