Teens: This is how social media affects your brain — Prevent Child Abuse Delaware. CNN | By Susie East August 1, 2016 - Whether you're on Facebook, Instagram, Snapchat, What's App or Twitter, the way you communicate with friends today is changing. Keeping in touch is no longer about face to face, but instead screen to screen, highlighted by the fact that more than 1 billion people are using Facebook every day. Social media has become second nature -- but what impact is this having on our brain? Reward circuitry In a recent study, researchers at the UCLA brain mapping center used an fMRI scanner to image the brains of 32 teenagers as they used a bespoke social media app resembling Instagram.
By watching the activity inside different regions of the brain as the teens used the app, the team found certain regions became activated by "likes", with the brain's reward center becoming especially active. The teenagers were shown more than 140 images where 'likes' were believed to from their peers, but were in fact assigned by the research team. Peer influence Social learning. Adult drinking habits in Great Britain - Office for National Statistics. 28.9 million people report that they had drunk alcohol in the week before interview. 2.5 million people drink more than 14 units of alcohol on their heaviest drinking day.

Animated Infographic: Monitoring the Future 2014 Survey Results. U.S. teens have sex at about the same age as their parents. NEW YORK, April 2 (UPI) -- Many U.S. parents say they think teens are having sex earlier and earlier, but researchers say today's teens have sex at about the same age as their parents. The study, published online in the journal Pediatrics, found 0.6 percent of 10-year-olds, 1.1 percent of 11-year-olds and 2.4 percent of 12-year-olds said they had sex. However, sex among very young adolescents was frequently involuntary, the study found. The study also found 33 percent of those age 16, about half of those age 17, 61 percent of 18-year-olds and 71 percent of 19-year-olds said they have had sex -- a pattern that has prevailed for decades. Lawrence B. Finer and Jesse M. Philbin of the Guttmacher Institute in New York said a low level of sexual activity among young adolescents has long been the norm, while sexual initiation later in adolescence has been and remains a normal part of teens' development process. © 2013 United Press International, Inc.
Lawrence B. American Teens' Sexual and Reproductive Health. May 2014 •Fewer than 2% of adolescents have had sex by the time they reach their 12th birthday. But adolescence is a time of rapid change. Only 16% of teens have had sex by age 15, compared with one-third of those aged 16, nearly half (48%) of those aged 17, 61% of 18-year-olds and 71% of 19-year-olds.[1] There is little difference by gender in the timing of first sex. •On average, young people have sex for the first time at about age 17, [2] but they do not marry until their mid-20s.[3] This means that young adults may be at increased risk for unintended pregnancy and STIs for nearly a decade or longer. •Teens are waiting longer to have sex than they did in the recent past. •In 2006–2010, the most common reason that sexually inexperienced teens gave for not having had sex was that it was “against religion or morals" (38% among females and 31% among males). •Teen sex is increasingly likely to be described as voluntary.
