For years the scientific literature has associated TV with inactivity and obesity in young people. Now, research led by the University of Zaragoza and São Paulo shows the links between the habit and increased risk of developing hypertension.
The work shows the number of new cases of hypertension and the connection between physical activity and sedentary behaviors with different risk of high tension in European children.
Scientists were based on data from the study on the identification and prevention of induced health diet and lifestyle in children (IDEFICS) effects, collected during two years in 5,221 children from 8 countries Europe (Spain, Germany, Hungary, Italy, Cyprus, Estonia, Sweden and Belgium), whose initial age was 2-10 years.
The results recently published in “International Journal of Cardiology” show that the cumulative incidence of hypertension in this population during the two years analyzed is high: 110 in 1000. Hypertension can cause cardiovascular problems in adulthood. For example, increases the risk of ischemic heart disease.
The authors state that children who remain sedentary for more than two hours a day watching television, computers and game consoles, are at a 30% higher risk of developing hypertension. The figures are worrying because sedentary behaviors are common in childhood and later adulthood.
Among non-communicable diseases, hypertension has a high incidence in adults. Studies have shown that levels of blood pressure in childhood and adolescence impact on the development of hypertension in adulthood. To combat this condition, experts recommend that young physically active for 60 minutes a day and advice sedentary activities not exceeding two hours daily. Researchers also have found that no physical activity one hour per day increases the risk of hypertension by 50%. The scientific evidence indicates that physical activity is a potent vasodilator. Therefore, increases oxygenation of the heart rate and, in turn, lowers blood pressure.
