Social jetlag upping diabetes risk, hurting heart

Washington: The rock star lifestyle may be better for you than watching movies all weekend and getting up early for work on Monday, according to a new study.

Even routine sleep changes such as waking up early for work during the week may raise the risk of developing metabolic problems such as diabetes and heart disease, according to the University of Pittsburgh study.

Researchers have long recognized that shift work can contribute to metabolic risk because of the continual disruption to the circadian system. Shift workers are more likely to develop metabolic syndrome, coronary heart disease and Type 2 diabetes than employees with regular daytime shifts.

Sleep disruption is among the factors that have contributed to rising rates of diabetes and obesity. More than 29 million Americans have diabetes, and 35.1 percent of American adults are obese, according to the Endocrine Society’s Endocrine Facts and Figures report.

Social jetlag refers to the mismatch between an individual’s biological circadian rhythm and their socially imposed sleep schedules. Other researchers have found that social jetlag relates to obesity and some indicators of cardiovascular function, said Patricia M. Wong.

Wong noted that this is the first study to extend upon that work and show that even among healthy, working adults who experience a less extreme range of mismatches in their sleep schedule, social jetlag can contribute to metabolic problems. These metabolic changes can contribute to the development of obesity, diabetes and cardiovascular disease.

The study is published in the Journal of Clinical Endocrinology & Metabolism. (ANI)
