Health News Roundup: August 16-September 9
|September 9, 2013||Posted by The Fit Scoop under News and Research|
I realized today that I’m behind on the health news roundup – apologies! Here’s a quick roundup of various health and fitness related news from the past few weeks.
– If you are going to have a heart attack, do it at the gym. A study published in the Journal of the American College of Cardiology found that individuals who went into cardiac arrest at fitness centers were more likely to survive than those at other public facilities. The survival rates were 56% for individuals at conventional fitness centers, 45% at other exercise facilities (i.e. indoor tennis courts or bowling alleys), and 34% at all other public locations.
– More evidence that breastfeeding is protective against breast cancer. A study in the Journal of Clinical Nursing found that breastfeeding for longer than 6 months helps to protect against breast cancer, even in cases where there is a history of breast cancer. However, the protective effect was not observed in women who were smokers.
– At a meeting of the European Society of Cardiology, researchers presented data that suggests Tour de France riders have lower mortality rates than expected for their age. They found the average French participant lives 6 years longer than their age-matched countrymen. This stands in contrast to recent studies that suggest extreme endurance exercise is potentially deadly.
– A study in Science suggests that gut bacteria may play a role in making you fat or thin. Scientists transferred gut bacteria from obese and lean twins into mice and discovered that the mice given bacteria from the obese twin gained more weight and packed on more adipose tissue than mice that received bacteria from the thin twin. This provides further support for the notion that ‘gut bugs’ have a significant impact on metabolic health.
– A recent study on breast cancer supports recommending mammographic screening before the age of 50. In a study of 7,300 breast cancer patients, 71% of deaths occurred in women who were unscreened.
– In case you need more evidence that staying physically active is important for healthy aging, a study published in the British Journal of Sports Medicine found that older men who exercised vigorously at least 150 minutes each week were more likely to live longer and age better than their sedentary counterparts. It is interesting to note that those who stopped exercising lost many of these benefits, whereas those who started exercising later in life were able to gain these benefits.
