Marriage may protect against heart disease/stroke and associated risk of death
The findings prompt the researchers to suggest that marital status should be included as a risk factor for heart disease/stroke and likely survival in its own right.
Most (80%) cardiovascular disease can be attributed to well known risk factors: age; sex; high blood pressure; high cholesterol; smoking; and diabetes. But it’s not clear what influences the remaining 20 per cent.
The findings of previous research on the impact of marital status have been somewhat mixed, so in a bid to clarify the issues, the authors trawled research databases for relevant published studies.
They drew on 34 out of a total of 225, all of which had been published between 1963 and 2015, and involved more than 2 million people aged between 42 and 77 from Europe, Scandinavia, North America, the Middle East, and Asia.
Pooled analysis of the data revealed that, compared with people who were married, those who weren’t (never married, divorced, widowed) were at heightened risk of developing cardiovascular disease (42%) and coronary artery heart disease (16%).
Not being married was also associated with a heightened risk of dying from both coronary heart disease (42%) and stroke (55%).
