Question

                                     B 

           Teens who spend hours on the Internet may be at risk for high blood pressure. Researchers found that teens who spent at least 14 hours a week on the Internet had their blood pressure increased. Of 134 teens described by researchers as heavy Internet users,26 had higher blood pressure.

           This is believed to be the only study to show a link between time spent on the Internet and high blood pressure. The findings add to growing research that has shown an association between heavy Internet use and other health risks like anxiety,depression,obesity and social isolation.

          “Using the Internet is part of our daily life,but it shouldn’ t  destroy us,” says Andrea,a researcher at Henry Ford's Department of Public Health Sciences and the study's  lead author. uIn our study,teens considered heavy Internet users were on the Internet an average of 25 hours a week. It's important that young people take regular breaks from their computers or smartphones,and engage in some form of physical activity. I recommend children to limit their time at home on the Internet. I think two hours a day,five days a week is OK."

          Andrea says school nurses could condudt annual health screenings (检查) in which blood pressure and Internet use behavior could be assessed. Students with high blood pressure would then have a follow-up visit to determine the next step.

          Researchers analyzed data collected from 335 teens aged 14 to 17 who participated in the study. Participants completed a 5 5-question survey of their Internet use during one week. Researchers found that teens spent an average of 15 hours a week on the Internet at either school or home; 39 percent of girls were heavy Internet users compared to 43 percent of boys; 43 percent of heavy Internet users were considered overweight compared to 26 percent of light Internet users.
