One study found that watching more than two hours of television per day increased by 30% the risk of hypertension, and said he did not do at least one hour of daily physical activity increases this risk by 50%.
The research, led by the University of Zaragoza (Unizar) and São Paulo (Brazil), was based on data from the study on the identification and prevention of induced health effects of diet and style life in children (IDEFICS), collected during two years in 5,221 children from 8 European countries (Spain, Germany, Hungary, Italy, Cyprus, Estonia, Sweden and Belgium), whose initial age was 2-10 years.
“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,” said Augusto César F. de Moraes, a Brazilian researcher working with the Unizar group and lead author of the article, as published in the Spanish ABC.es website.
The results, recently published in the journal “International Journal of Cardiology”, showed 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, “said F. de Moraes.
In addition, the authors stated that children who remain sedentary for more than two hours a day watching television, computer and video consoles, run a 30% higher risk of developing hypertension.
“The figures are worrying because sedentary behaviors are common in childhood and later in adulthood “they said.
Moreover, the researchers found no physical activity at least an hour a 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, “explained lead author of the study.
