Long sleep in children appears to reduce their risk of diabetes
Lack of sleep has far-reaching effects on the cardiovascular system, metabolism and the brain. This obviously applies particularly to children. According to a message from the Professional Association of Pediatricians (BVKJ), a recent study by British researchers came to the conclusion that reduced sleep in children increases the risk of obesity and diabetes.
The British research team led by Dr. Alicja R. Rudnicka of the University of London found in his current study an inverse relationship between sleep duration, overweight and diabetes, reports the BVKJ. This means that children who sleep little tend to be overweight and diabetic. The results of the scientists were published in the "Pediatrics" journal.
Connection with diabetes risk markers
The researchers around Dr. In their cross-sectional study, Rudnicka from the University of London examined the data of 4,525 children with different ethnic backgrounds between the ages of 9 and 10 years for a connection between the self-declared sleep duration and risk markers for type 2 diabetes. They found that the children slept an average of 10.5 hours a night, and that there is a highly inverse relationship between sleep duration and diabetes risk factors. The BVKJ reports that insulin resistance in the model evaluation was 2.9 percent lower and fasting blood sugar was 0.24 percent lower if the children slept an hour longer each night.
Lower BMI and fat mass index for longer sleep
According to the scientists, an hour more sleep also correlated with 0.19 kg / m² less BMI and a 0.03 kg / m² lower fat mass index (calculated as fat mass / size squared; measure for the body's relative fat content), the report said of the BVKJ. However, a connection with an increased cardiovascular risk was not found in the current study. Even after taking into account the risk factors associated with being overweight, the connection between lack of sleep, insulin and blood sugar levels persisted.
Additional studies required
Another evaluation recently published in the specialist magazine "Pediatrics" by scientists from the University of California Davis, Sacramento shows that in most of the studies available to date, a correlation between sleep duration and the risk of being overweight was found. What is new, however, is the reverse association between sleep duration and risk markers of type 2 diabetes in childhood, which the University of London scientists have uncovered. Further studies are now necessary to determine whether there is a cause-effect relationship, according to the BVKJ. (fp)
