Researchers based at Aston Medical School, Birmingham, monitored the survival of over a million people who had risk factors for heart disease – high blood pressure, high cholesterol and type 2 diabetes.
They discovered that people with high cholesterol were 16 per cent more likely to be alive at the end of the study if they were married.
The same was true for diabetes and high blood pressure, with married people having 14 per cent and 10 per cent higher survival respectively compared to those who were single. The
support offered by a spouse may be the reason for survival.
Researchers suspect that people are better at managing these risk factors when they are supported by their loved one. The research suggests that marriage controls risk factors for heart disease.
