As a kind of addendum to my previous post, I wanted to note that another study has identified links between social interaction and health, not just with the elderly but at two distinct stages of life. Researchers associated with the University of North Carolina Chapel Hill used data from four national samples to determine if an association existed between elements of personal relationships and physical health markers. Published in the Proceedings of the National Academy of Sciences, the study concluded that level of social involvement and size of social network are associated with the risk of poor health. Among senior citizens, social connection was associated with lower risk of disease development, particularly around obesity and hypertension. An even more interesting finding – the level of social engagement among adolescents predicted their risk of health complications later in life.

At this time of year there is heightened awareness of the needs of others. We donate dollars, coats, toys and gifts, bags of food, or whatever else is needed to help make the holiday season a little less difficult for those facing economic hardship. But social needs are also important, and when they are neglected due to self-imposed or situational isolation, there is an emotional and physical toll. A holiday advertisement from the German store chain Edeka has been in the news this week for its powerful imagery of a lonely widower who is only able to bring his children and grandchildren together at Christmas by his (fake) death. Well played, Grandpa.
