Add protection from heart disease and stroke to the health benefits of marriage, a new study suggests.
Happily ever after
Researchers analysed data from 34 studies that were published between 1963 and 2015. They included more than 2 million people between the ages of 42 and 77, in Asia, Europe, the Middle East, North America and Scandinavia.
The investigators found that, compared to married people, those who were never married, divorced or widowed had a 42% higher risk of cardiovascular disease, a 16% higher risk of coronary artery disease, a 42% higher risk of death from coronary heart disease, and a 55% higher risk of death from stroke.
The British researchers also found that among both men and women, divorce was associated with a 35% higher risk of heart disease, and that widowers were 16% more likely to have a stroke.
There was no difference in the risk of death following a stroke between married and unmarried people. But those who had never married were 42% more likely to die after a heart attack than those who were married, the findings showed.
South African picture
According to Stats SA, four out of 10 South African marriages end in divorce. However, it seems that there are fewer divorces than a decade ago.
The researchers said their findings suggest that marital status might be an independent risk factor for heart disease and stroke, and for the likelihood of dying from those conditions.
But the study did not prove that marriage caused heart risks to drop.
The findings were published online in the journal Heart.
"Future research should focus around whether marital status is a surrogate marker for other adverse health behaviour or cardiovascular risk profiles that underlies our reported findings or whether marital status should be considered as a risk factor by itself," the team led by Mamas Mamas, a professor at Keele University in Stoke on Trent, wrote in a journal news release.
There are a number of theories as to why marriage may benefit people's health. They include earlier detection and treatment of health problems; better adherence to medication regimens; greater financial security; enhanced well-being; and larger friendship networks.
