Healthy Habits Are Most Contagious Among Similar Friends

Obesity spreads contagiously throughِ social networks, claimed a highly publicized 2007 study, andِ since then, someِ researchers haveِ beenِ working toِ use social networks toِ reverse theِ nation’s obesity epidemic.
Researchers atِ MIT foundِ that byِ bringing people whoِ hadِ similar traits togetherِ intoِ a social network, withِ theِ aim ofِ increasing physical fitness, theyِ increased howِ many people picked upِ a newِ activity thatِ couldِ bring aboutِ healthy lifestyle changes.
Even people whoِ wereِ obese wereِ moreِ likelyِ to pick upِ theِ newِ activity whenِ grouped withِ otherِ obese people thanِ when grouped withِ thinner people.

The study may open up new avenues of research.

You’re goingِ to seeِ a lot moreِ weight-loss] interventions coming downِ the road thatِ areِ thoughtfully designed aroundِ social networks.
And asِ a result, I thinkِ those interventions areِ going toِ beِ more successful, saidِ Ray Browning, a physiologist atِ Colorado State University whoِ hasِ studied health interventions andِ social networks, butِ was notِ involved withِ theِ newِ study.

Health buddies

For theِ study, researchers worked withِ 710 participants, mostِ of whomِ wereِ women, whoِ hadِ enrolled inِ anِ online fitness program.
Participants wereِ able toِ seeِ anonymous profiles ofِ their health buddies, asِ well asِ certain fitness activities theyِ did, suchِ asِ the time theyِ spent exercising andِ whether theyِ were keeping a diet diary – writing downِ the foods theyِ ate.
While public health researchers mayِ target network-based interventions forِ weight loss, Browning saysِ the research canِ alsoِ provide someِ insight forِ anyoneِ who wantsِ toِ lose weight.

Life changes

While notِ well-studied, Browning noted thatِ researchers haveِ observed thatِ someِ people whoِ sustain weight loss forِ a long period alsoِ change whoِ theyِ spend theirِ time withِ — forِ example, a divorce orِ a move mightِ beِ involved.
The social network theyِ land inِ hasِ more ofِ these healthful behaviors.
And so, changing yourِ behaviors mayِ beِ easier ifِ you bring someoneِ newِ intoِ your group, suchِ asِ a personal trainer, whoِ canِ bring betterِ habits andِ activities thatِ promote health, Browning said.

Take your social network you have and bring in that seed individual, he said.

While theِ study showed someِ success, Browning noted theِ results mayِ not apply toِ everyone.
There wereِ proportionately fewerِ obese people inِ the study thanِ inِ the general population, andِ because theِ sample wasِ obtained fromِ a fitness group, people involved wereِ alreadyِ looking forِ ways toِ getِ healthier.
Additionally, itِ remains unclear howِ other newِ health behaviors mightِ spread throughِ a group, becauseِ keeping a log ofِ what youِ eat isِ easier thanِ beginning a rigorous exercise program.

Still, the study pushes the research in the right direction, he said.

This isِ a nice, elegant wayِ toِ start theِ discussion ofِ howِ to doِ interventions withِ regardsِ to social networks.

The study will be published tomorrow (Dec. 2) in the journal Science.
