Adults in the UK who have poor sleep patterns are more likely to be overweight and obese and have poorer metabolic health, according to a new study. The findings showed that people who were sleeping on average around six hours a night had a waist measurement that was 3cm greater than individuals who were getting nine hours of sleep a night. And shorter sleepers were heavier too. The results strengthen the evidence that insufficient sleep could contribute to the development of metabolic diseases such as diabetes -- major health challenges facing the NHS. The study -- led by Dr Laura Hardie, Reader in Molecular Epidemiology at the University of Leeds -- not only looked at the links between sleep duration, diet and weight, but also other indicators of overall metabolic health such as blood pressure, blood cholesterol, blood sugar, and thyroid function. The study involved 1,615 adults who reported how long they slept and kept records of food intake. Participants had blood samples taken and their weight, waist circumference, and blood pressure recorded.
The researchers looked at the associations between how long people were sleeping and these key biological parameters.
