Obesity's Link to Poor Health Queried
Obesity Health Link Queried
http://www.staffnurse.com/nursing-ne...ried-2110.html People who are overweight may not be at immediate risk of dying - unless they have diabetes, researchers reported today. A new study suggests that obesity on its own carries no immediate threat to life. Researchers found that diabetes - which often follows from obesity - carries a high risk of dying or developing failure of major organs such as the heart or liver. The study in the journal Critical Care concludes that having diabetes increases the threat of dying by three times. Researchers found that obese people, who did not have diabetes, carried no extra risk of dying compared with slim people. The study was performed over a three year period and the conclusion is likely to be that "healthy" obese people have a chance to slim down before suffering long term effects from their excess weight. Researchers at the University of Kentucky, USA, studied details of more than 15,000 people aged between 44 and 66, tracking their health over a three-year period. Researcher Katarina Slynkova reports: "These findings call for further investigation to determine the mechanisms that underlie this complex relationship between obesity, diabetes, and critical illness." Meanwhile a second piece of research, reported at the weekend, challenges the idea that regular walking may help health. The findings, reported to the conference of the American College of Sports Medicine, came from a limited study of the health effects of walking. Researchers from the University of Alberta, Canada, studied features such as lung capacity and glucose levels after a six months training programme. They found that counting steps, 10,000 of them, increased lung capacity by just four per cent whilst adding some intensity to the programme boosted it by ten per cent. Neither had any impact on glucose or blood fat levels. |
