Summary: A comprehensive study underscores the alarming link between social isolation, loneliness and elevated mortality risks.
A meta-analysis involving more than two million participants found a significant increase in all-cause mortality rates for socially isolated and isolated individuals. Also, these risks are increased in individuals with pre-existing health conditions such as cardiovascular disease or breast cancer.
These findings emphasize the importance of prioritizing community health to increase public well-being and reduce mortality risks.
- Social isolation was associated with a 32% increased risk of all-cause mortality and a 24% increased risk of cancer mortality.
- Loneliness was associated with a 14% increased risk of all-cause mortality and a 9% increased risk of cancer mortality.
- For individuals with pre-existing health conditions such as cardiovascular disease or breast cancer, social isolation is linked to an increased risk of all-cause mortality and cancer-related mortality.

A recent comprehensive meta-analysis of prospective cohort studies, including more than 2 million individuals, revealed strong associations between social isolation, loneliness, and increased mortality.
These findings highlight the critical importance of social interactions to our overall health, serving as a poignant reminder of our inherently social nature.
The profound impact of social isolation and loneliness on our health
This groundbreaking study sheds light on the significant health risks associated with both social isolation and loneliness.
Social isolation was found to be associated with a 32% increased risk of death from all causes.
Similarly, loneliness was associated with a 14% increased risk. When we examine specific causes of death, such as cancer, the results are equally startling.
Social isolation and loneliness were associated with a 24% and 9% increased risk of cancer death, respectively. Furthermore, social isolation was found to increase the risk of death from cardiovascular diseases (CVD) by 34%.
A closer look at people with pre-existing health conditions
When the researchers focused on individuals with pre-existing health conditions such as CVD or breast cancer, the results were no less striking.
Socially isolated individuals with CVD or breast cancer had a 28% and 51% increased risk of all-cause mortality, respectively. Also, socially isolated individuals with breast cancer face a 33% higher risk of cancer-related mortality.
These data paint a stark picture of how our social experiences can significantly affect our physical health, even when dealing with serious medical conditions like CVD and cancer.
Explaining the implications
These findings not only underscore the serious health implications of social isolation and loneliness, but also the need to prioritize social health as an important aspect of public health.
The health risks associated with social isolation and loneliness are significant and cannot be ignored.
The question then becomes: How can we reduce social isolation and loneliness, particularly among people with existing health conditions?
Need for comprehensive public health strategies
The solution requires comprehensive, multi-pronged strategies at the community level. We need to foster communities that encourage social interaction and foster supportive relationships.
Health practitioners should be aware of the health risks associated with social isolation and loneliness, and integrate assessments of social health into routine health screenings.
Programs that facilitate social interactions, such as social activities and support groups, are particularly beneficial for individuals with pre-existing health conditions. For these individuals, fostering social interactions can serve as an important aspect of disease management and can improve both their quality of life and their prognosis.
In a world where social isolation and loneliness are increasingly prevalent, these findings are a reminder of the profound impact our social experiences have on our health.
The complex relationship between social experiences and health outcomes is an active area of research, with the hope that further investigations will reveal actionable insights to improve public health.
The evidence is clear: We must address the health risks associated with social isolation and loneliness. By fostering social connections and prioritizing community health, we can improve the well-being of our communities and reduce the risk of death among socially isolated and lonely people.
The health of our societies depends not only on medical progress, but also on our ability to communicate with each other.

A systematic review and meta-analysis of 90 cohort studies on social isolation, loneliness and mortality
The links between social isolation, loneliness and risk of death from all causes, cardiovascular disease (CVD) and cancer are controversial.
We systematically reviewed and conducted a meta-analysis of prospective studies of the relationship between social isolation, loneliness, and mortality outcomes in individuals aged 18 years or older, and of these relationships in individuals with CVD or cancer.
The study protocol was registered in PROSPERO (registration no. CRD42022299959). A total of 90 prospective cohort studies including 2,205,199 individuals were included.
Here we show that in the general population, both social isolation and loneliness were significantly associated with increased risk of all-cause mortality (pooled effect size for social isolation, 1.32; 95% confidence interval (CI), 1.26 to 1.39; B< 0.001; pooled effect size for loneliness, 1.14; 95% CI, 1.08 to 1.20; B<0.001) and cancer mortality (pooled effect size for social isolation, 1.24; 95% CI, 1.19 to 1.28; B< 0.001; Pooled effect size for loneliness, 1.09; 95% CI, 1.01 to 1.17; B= 0.030).
Social isolation also increased the risk of CVD mortality (1.34; 95% CI, 1.25 to 1.44; B<0.001). CVD (1.28; 95% CI, 1.10 to 1.48; B= 0.001) or breast cancer (1.51; 95% CI, 1.34 to 1.70; B<0.001), and individuals with breast cancer had higher cancer-specific mortality due to social isolation (1.33; 95% CI, 1.02 to 1.75; B= 0.038).
A greater focus on social isolation and loneliness could help improve people’s well-being and risk of death.
