Following the crowd may not always be in a person’s best interest．But new research suggests that teens who go along with their friends may end up healthier as adults．
Scientists have known that close friendships help boost health．That’s true for both teens and adults．The finding inspired Joseph Allen，a psychologist at the University of Virginia，and his team to study whether experiences during teen years would influence adult health．
So they followed 171 teens，starting when the kids were just 13．They interviewed each one every year for five years，and also spoke to these teens’closest friends，who provided additional information about the quality of their friendships．The same 171 people were interviewed again at ages 25，26 and 27．This time，the questions surveyed each person’s overall health．When the researchers analyzed the data they found a strong connection between a teen’s behavior and adult health．Teens who had close friends grew up to be the healthier adults．Whether teens held back their feelings or expressed them to a close friends also influenced later health．Those who held back were more likely to be sick as adults．The connection held up even after the scientists accounted for other possible influences on health．Weight，family income and drug use were all examined．So were mental health issues，such as anxiety and depression．And in these people，such other factors did not explain adult health as well as teen friendships did．
Going along with the crowd may have benefits，says Allen，but there are also drawbacks．Teens who are more independent tend to do better at school and work．And peer pressure may lead some kids to engage in risky behavior，such as smoking，drinking or using drugs．Dealing with it is an ongoing challenge，Allen acknowledges．“Finding the right balance is the key．Teens shouldn’t lose heart for not finding this easy．”And，he adds，“Parents need to be understanding about the pressures teens face.”
