Birds of a feather flock together -- even when it comes to health habits.


A new study from Gallup researchers shows that if your friends and family engage in unhealthy habits such as drinking, smoking or being inactive, you are more likely to do so as well.


Gallup's annual Consumption Habits Survey[1] shows that Americans associate themselves with people who share their health habits. Gallup conducted telephone interviews with 2,027 U.S. adults from July 10 to 14.


Forty-six percent of adults who considered themselves to be alcohol drinkers said many or some of their friends and family members drink. Comparatively, only 30 percent of nondrinkers thought many or some of their social group drinks. Researchers also noted that Americans are most likely to have friends and family who drink regardless of their personal alcohol consumption since nearly 60 percent of Americans drink alcohol "at least occasionally."


Results also showed that people who smoke were twice as likely to associate themselves with other smokers. Similarly, researchers found that individuals who identified themselves as overweight were more likely to say they have some or many friends and family members who are overweight than those who considered themselves to be a healthy weight.


While it is clear that there is a strong association between a person's health and their circle of friends and family, we don't know if it is the group that influences the individual, or if we tend to seek out those who share our habits. However, we do know that friends can also be our greatest motivators[2] in restoring our health.

  • Friends Get You Moving


    Research presented in 2012 found that something you might expect more from your mother -- nagging -- can actually work when it's coming from a pal who's pushing you to move more.

    In fact, the least active interviewees in this particular survey said they <a href="http://www.sciencedaily.com/releases/2012/04/120418134852.htm" target="_hplink">needed and even <em>appreciated</em> a nudge</a> now and then from friends.

    And working out with a friend has the added benefit of keeping you committed to your workout plan. There's no rolling over to hit the snooze button on that a.m. run if someone is waiting for you to show up!

  • Friends Keep You Relaxed


    There's some truth behind friendship clichés like "a shoulder to cry on." In the face of great stress, talking with and leaning on friends really can help you get through troublesome times.

    A 2011 study found that among students, <a href="http://www.sciencedaily.com/releases/2011/10/111026091229.htm" target="_hplink">friendships helped reduce some of the stress of being bullied</a> or excluded at school.

    Women in particular may be predisposed to the calming benefits of friendship. Researchers found that <a href="http://www.sfgate.com/opinion/article/Fight-stress-with-friends-2858415.php" target="_hplink">females release the hormone oxytocin when stressed</a>, which encourages "tend and befriend" behavior, rather than the "fight or flight" reaction often observed in men, the <em>San Francisco Chronicle</em> reported. This encourages women to chat with their friends when stressed, and the chatting itself spurs the release of <em>more</em> oxytocin, which can have a calming effect.

  • Friends Help You Live Longer


    It's not quite as simple as connecting with friends and, poof, you're guaranteed to live to 100. But there <em>is</em> a significant body of research linking strong social ties to a longer lifespan.

    Australian research found that <a href="http://jech.bmj.com/content/59/7/574.abstract?maxtoshow=&HITS=10&hits=10&RESULTFORMAT=&fulltext=friends&andorexactfulltext=and&searchid=1&FIRSTINDEX=0&sortspec=date&resourcetype=HWCIT" target="_hplink">older adults with more friends were 22 percent less likely to die</a> during a 10-year study than their peers with fewer friends.

    And in a recent analysis of 148 studies, researchers found that people with stronger relationships had a <a href="http://www.plosmedicine.org/article/info:doi/10.1371/journal.pmed.1000316" target="_hplink">50 percent greater chance of survival</a>.

  • Friends Boost Cancer Survival Rates


    While friendships may help you live longer in any situation, social ties have also been linked specifically to overcoming cancer.

    A small 2005 study observed 61 women with advanced ovarian cancer. <a href="http://onlinelibrary.wiley.com/doi/10.1002/cncr.21147/abstract" target="_hplink">Higher levels of interleukin 6</a>, a protein marker for a more aggressive form of the disease, were found in the women with the weakest social bonds.

    An older study followed 86 women with metastatic breast cancer for a year and found that the women who participated in a weekly support group <a href="http://www.ncbi.nlm.nih.gov/pubmed/2571815" target="_hplink">lived twice as long</a>.




  • Friends Lower Heart Disease Risk


    Perhaps because of their relaxation powers, friends are also good for the heart. A 2005 analysis of social support theories found that weak social ties could <a href="http://www.ncbi.nlm.nih.gov/pubmed/16314591" target="_hplink"><em>double</em> heart disease risk</a>.

    The link between social support and a healthy heart is even stronger for men who make one very special social tie official. <a href="http://www.webmd.com/balance/news/20041108/social-ties-guard-against-heart-disease" target="_hplink">Married men</a> seem to experience a particular boost in heart health, WebMD reported.

    Stronger social ties in general seem to lower blood pressure, which helps the heart.
