This is shocking news to all parents and also to the children’s as they started to worry about their health.

                       The major concern among the people in the recent trend is their health problems mainly obesity, because obesity has got direct effect on blood pressure. The author had given a statement that the risk of getting the cardiovascular diseases in overweight youths is high. Genetic factors, sleeping habits, healthy physical and dietary have some contribution in elevated blood pressure among the children. Even then also there is no clear picture of relation between elevated blood pressure and sedentary behavior in children under the age of nine years.

                           In order to find the association between sedentary behavior and elevated blood pressure, David Martinez-Gomez, B.Sc., of Lowa State University, Ames and the Spanish National Research council, Madrid, Spain examined 111 children in the range of 3 to 8 years of age which includes 57 boys and 54 girls. Sedentary behavior was determined by the accelerometer kept around the right hip and by the parents report on the average time spent in watching TV, sitting, painting, playing video games or other activities which does not include any physical activities for seven days. Screen time is defined by the researchers as the total amount of time spent in watching TV, using computer, playing video games and videos. Every child was checked for their weight, height, fat mass and the blood pressure.

                           The average screen time and sedentary time were found to be 5 hours and 1.5 hours. According to the author, sedentary activity has not impact on the blood pressure. But, screen time has an impact in the blood pressure. Children who were in the team of reduced screen time had less impact in blood pressure compared to other team of children with thrice the screen time. So, the author came to the conclusion that screen time was associated with the elevated blood pressure in children.
