Television viewing and lack of exercise at age 16 is associated with the risk of developing metabolic syndrome at 43 years age, a team of scientists has found.
Metabolic syndrome is a name for the disorder of metabolism - a combination of abdominal obesity, elevated blood lipids, hypertension and impaired glucose tolerance - which provides for a significantly increased risk of developing type 2 diabetes, stroke and cardiovascular disease.
It has previously been shown that lack of physical activity increases the risk of metabolic syndrome. It is also known that low leisure-time physical activity, for example, how much time spent watching TV is linked to the risk of metabolic syndrome independent of exercise habits.
The new research findings have now been able to show that these relationships extend over a large part of life, specifically between 16 to 43 years of age.
The study was conducted by scientists at Umea University, in collaboration with colleagues in Melbourne, Australia and included 888 participants in northern Sweden who had been followed from 1981 when they were in ninth grade in elementary school, until 2008.
"The results demonstrate that we need to consider how we can reduce sedentary lifestyle among children and adolescents," said lead author, a general practitioner and Adjunct Professor Patrik Wennberg, Department of Public Health and Clinical Medicine, Umea University.
"It may be more important than only focusing on increased fitness and sports activities for those who are already interested," he added.
The study has been published in the journal Diabetes Care.
