YORK, UK — Although past research has shown a link between impaired social relationships and premature mortality, a new meta-analysis suggests there may also be a significant association with increased risk for coronary heart disease (CHD) and stroke.
The review of 23 papers and 181,006 total patients showed a 29% increased risk for incident CHD for those who had poor social connections, shown through loneliness and social isolation measurements, compared with those with better connections. The lonely and isolated patients also had a 32% increased risk for stroke.
The investigators, led by Dr Nicole K Valtorta (University of York, UK), note that loneliness often contributes to impaired coping methods, isolation affects self-efficacy, and both have been associated with decreased physical activity and increased smoking.
They add that future studies are needed to assess whether targeting these social characteristics "can help to prevent two of the leading causes of death and disability in high-income countries." But for now, "health practitioners have an important role to play in acknowledging the importance of social relations to their patients."
