Marriage appears to be good for your health, boosting your survival chances if you have a major heart risk factor such as high cholesterol, say researchers.
A loving spouse might spur you on to look after yourself better, they told a heart conference, based on their study of nearly a million UK adults.
All of these people had high blood pressure, cholesterol or diabetes.
The married ones fared much better than those who were single.
Dr Paul Carter and colleagues at Aston Medical School, who carried out the work, have already shown that marriage is linked to a better chance of surviving a heart attack.
Their latest research, presented at the British Cardiovascular Society conference, hints at why this might be.
They suspect marriage helps buffer against big heart disease risk factors, including cholesterol and high blood pressure.
The study looked at deaths from all causes, including heart disease.
Men and women in their 50s, 60s and 70s with high cholesterol were 16% more likely to be alive at the end of the 14-year ACALM study if they were married rather than single.
The same was true for diabetes and high blood pressure, with married people having a survival advantage.
The picture was less clear for people cohabiting, separated, divorced or widowed.
Also, the researchers did not test if the wedded people were in happy marriages.
They suspect having someone special in your life is what’s important, rather than simply getting hitched.
Dr Carter said: “We need to unpick the underlying reasons a bit more, but it appears there’s something about being married that is protective, not only in patients with heart disease but also those with heart disease risk factors.
“We’re not saying that everyone should get married though.
“We need to replicate the positive effects of marriage and use friends, family and social support networks in the same way.”
Dr Mike Knapton, of the British Heart Foundation, said: “The take-home message is that our social interactions, as well as medical risk factors such as high blood pressure, are important determinants of both our health and wellbeing.
“Whether you are married or not, if you have any of the main risk factors for heart disease, then you can call upon loved ones to help you to manage them.”
Heart risk factors:
- high blood pressure
- high blood cholesterol
- being overweight/obese
- being physically inactive
- family history of heart disease
- age (risk goes up with age)
