Heart: the single dog has been critically hit again! Marriage can prevent cardiovascular disease and stroke

June 24, 2018 / BIOON / - a new study published in heart recently found that marriage may protect people from heart disease or stroke, as well as those at high risk The findings prompted the researchers to suggest that marital status should also be a risk of heart disease and stroke, as well as possible survival Source: cc0 public domain most cardiovascular diseases (80%) can be attributed to known risk factors: age, gender, hypertension, high cholesterol, smoking and diabetes But it's not clear what caused the remaining 20% In order to clarify this problem, the researchers searched all the existing studies in the database They focused on 34 of 225 studies, all published between 1963 and 2015, involving more than 20 million people aged 42-77 from Europe, North America, the Middle East, Asia and Scandinavia A pooled analysis of these data by the researchers found that people who were not married (never married, divorced, widowed) had an increased risk of cardiovascular disease and relationships (42% and 16%, respectively) compared with those who were married The risk of dying of coronary heart disease and stroke was also increased in people who had never been married (42%, 55%) If the data were further categorized, the researchers found that divorced people had a 35% increased risk of heart disease, while widowed people had a 16% increased risk of stroke Although marriage had no significant effect on the risk of death after a stroke, the risk of dying from a heart attack increased by 42% for people who had never married The authors also indicated that the different methods used in all studies and the correction methods may affect their analysis results Although there is no data on same-sex couples, the quality of marriage, and the impact of living with someone (but not married) on cardiovascular disease But the authors point out that this is the largest study to date, with a wide age and ethnic distribution of participants, which also enhances the reliability and adaptability of the results At present, there are many theories about why marriage has protective effects, including early awareness and measures for health problems, more likely to seek medical treatment, better financial security, increased happiness, better friendship network, etc "Future research will focus on whether marital status can be used as a marker for other serious health behaviors or cardiovascular risk events we report, or whether marital status is a risk factor in itself."
