The Claim
Adults with the lowest level of social integration have 2.66 times higher odds of dying from coronary heart disease over a 15-year period compared to adults with the highest level of social integration, after adjustment for age, gender, and Framingham cardiovascular risk score.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Over a 15-year period, adults who had fewer social connections were 2.66 times more likely to die from coronary heart disease than those with more social connections, even when accounting for age, sex, and traditional cardiovascular risk factors.
See the scientific wording
Adults with the lowest level of social integration had 2.66 times higher odds of dying from coronary heart disease over 15 years compared to those with the highest level of social integration, even after adjusting for age, gender, and Framingham cardiovascular risk score, indicating social isolation is an independent predictor of CHD mortality.
When people feel very alone for a long time, their bodies produce more of a chemical that causes swelling inside blood vessels. This swelling damages the inside of the arteries over time, making plaques build up faster. These plaques can block blood flow to the heart, leading to heart attacks and death.
What the research says
1 studyPeople who felt more alone were more than twice as likely to die from heart disease over 15 years, even when accounting for things like age and cholesterol. This suggests being socially isolated is a real health risk, just like smoking or high blood pressure.
