Long sleepers with a risk of obesity were about 4kg heavier and short sleepers were about 2kg heavier than those with a similarly high genetic obesity risk with normal sleep durations. The University of Glasgow study also found no clear link between sleep duration and body weight in those with a low genetic risk of obesity. The study found abnormal sleeping patterns increased the risk of being overweight for those genetically predisposed to obesity. "However, the influence of adverse sleep characteristics on body weight is much smaller in those with low genetic obesity risk - these people appear to be able to 'get away' with poorer sleep habits to some extent." Co-author Dr Carlos Celis said: "It appears that people with high genetic risk for obesity need to take more care about lifestyle factors to maintain a healthy body weight.
Sleeping habits linked to increase in obesity
Long sleepers with high genetic risk of obesity were about 4 kg heavier, and short sleepers were about 2 kg heavier, than those with similarly high genetic obesity risk with normal sleep durations. Sleeping habits linked to increase in obesityGetting a bad night's sleep could be increasing some people's likelihood of becoming obese.According to a study led by the University of Glasgow, and published today in the American Journal of Clinical Nutrition (AJCN), abnormal sleeping habits increase the risk of obesity for those who are genetically predisposed to being overweight. The authors suggest that these findings make a case for further intervention studies to determine the benefits of healthier sleeping habits, particularly in individuals genetically susceptible to obesity. Researchers looked at the effects of abnormal sleeping habits such as short sleep duration (less than 7 hours sleep a night) and long sleep duration (more than 9 hours sleep a night), along with daytime napping and shift work.
