Research Roundup

  • Being overweight may trigger asthma. Though doctors have long assumed asthma leads to obesity by limiting physical activity, Harvard researchers now believe it may be the other way around, at least some of the time.

In a study of almost 90,000 female nurses, age 27 to 44, those who were more than 35% overweight were three times more likely to develop asthma over a four-year period those of ideal weight. Even being a little overweight increased the risk somewhat.

Why obesity contributes to asthma is not clear, though it may involve an inability to expand the lungs fully, increasing susceptibility to asthma triggers. Or, overweight people may spend more time indoors, where they are in closer proximity to allergens like dust, molds and pet hair.

  • Men who exercise regularly — 30 minutes five times a week—are 34% less likely to be troubled by gallstones than men who don’t exercise regularly. So concluded a study from Harvard’s School of Public Health of more than 45,000 men between the ages of 40 and 75.

Most activities tended to decrease the risk of gallstones, but only vigorous exercise such as jogging, running, racquet-sports and brisk walking significantly reduced the risk. The effect was greatest in younger men, but older men showed benefit simply from being less sedentary.
