* Socializing, whether via organizations or in close interaction with friends and neighbors, is associated with better self-reported health.* Over a 40 year period, people surveyed tended to participate less in organizations and visit less often with neighbors.* People who participated in sports clubs or who had more intense visits with friends had a higher probability of reporting good and excellent health than those who didn’t.

Newswise — While participating in social activities and organizations promotes health, having personal ties with friends is even better, finds a new study in the American Journal of Health Promotion.

“We all ‘know’ that friendships are ‘good for us,’” reports author Swati Mukerjee, Ph.D., “but there’s a gap between this accepted wisdom and researched fact.”

She reports that prior investigators had separately examined how personal and impersonal connections contribute to health. Her analysis also breaks new ground by examining the role of personal and impersonal connections for people of different genders, ages, races and education. ”In most demographic groups, friendship turns out to be very important” for self-reported health status, said Dr. Mukerjee.

Murkerjee analyzed data from 39,842 people using the General Social Survey conducted between 1972 and 2008. Respondents answered questions about their social characteristics, memberships, behaviors and attitudes and assessed their own health as either excellent, good, fair or poor. Previous research has shown that self-reported health status is a strong predictor of mortality.

Survey information about a person’s memberships in 16 categories of organizations, including unions, fraternities, sports, youth groups, etc. was used to measure level of impersonal connections. Information on how often the respondent spent the evening with relatives, neighbors or friends or visiting bars was used to measure personal connections.

Though Mukerjee found only a slight decline in the level of overall memberships between 1974 and 1994, she noted, “Larger shifts have taken place in the distribution of different memberships over time.” From 1974 to 1994, there was a 21 percent increase in the number of people joining sports clubs with a 12 percent reduction in volunteerism. Membership in a sports club was the only type of organizational connection found to increase the likelihood of a person reporting good to excellent health.

Personal interactions declined overall by about 12 percent during the study period, largely due to respondents reporting fewer visits with their neighbors, which declined by about 24 percent. Visits to friends had a small increase of five percent during the study period. People reporting intense personal interactions were more likely to report good to excellent health, compared to people without such interactions.

Dhaval Dave, Ph.D., an associate professor of economics at Bentley University and an economist with National Bureau of Economic Research, says, “Knowing that the decline in social interactions may have adverse effects on health can help individuals appreciate the costs and benefits of their actions.”

This knowledge, he adds, can also help policy-makers quantify the costs and benefits of policies that may impact social interactions. For example, Dave notes, if certain policies are known to reduce neighborhood crime, thus encouraging social life, then the health gains should be factored in to the cost benefit analysis of those policies. He added that these findings also hold important implications for retired and unemployed people and for anyone designing programs to assist them.
