Among men, the picture was quite different. Those who were single, shared a home with others, and had the largest social networks had the highest blood pressure, while those who had smaller networks and lived alone had lower blood pressure. The researchers found that combinations of different social ties also mattered. Regular social participation appeared to have a protective effect among non-partnered women, suggesting that health care providers may want to screen for the number of monthly social activities, and include these alongside healthy diet and exercise when treating non-partnered older women.
"Among women, the increase in blood pressure that was associated with the lack of social ties was similar to that seen with non-steroidal anti-inflammatory use, increased sodium diets pollution or weight gain," said Conklin. "This represents a significant women-specific risk factor for heart disease or stroke." Previous research by Conklin using the same data set found that women who were single, widowed, divorced or separated had higher odds of abdominal and general obesity, while men were less likely to be obese if they lived alone an d had a smaller social network.
"Taken with our previous research, our new findings underline how social isolation affects health in men and women differently," said Conklin. "At a time when Covid-19 is forcing us to limit our social interactions, it's important for those working in health care and public health to encourage older women, in particular, to find new ways to be socially active." Zeinab Hosseini, the lead author who contributed to the work as a former postdoctoral fellow at UBC said more studies are needed on how exactly social connections impact cardiovascular risk factors. "Prospective and intervention studies can help us understand this as well as why the associations are different for women compared to men," she said.
