A study by the American Cancer Society has found that the risk of cancer increases by 32% for individuals living alone.

It is widely known that living alone can be detrimental to both physical and mental health. Being alone may influence one’s lifestyle negatively, leading to unhealthy dietary habits, lack of physical activity, and an increased risk of mental health issues, such as feelings of loneliness, depression, and anxiety. Living with others can significantly reduce the likelihood of experiencing isolation.

On October 19, 2023, researchers from the American Cancer Society published a study in the journal “Cancer,” titled “Living alone and cancer mortality by race/ethnicity and socioeconomic status among US working-age adults.”

The study reveals that living alone increases the risk of cancer. Compared to those living with others, adults who live alone have a 32% higher risk of cancer-related mortality. Specifically, cancer mortality risk is 38% higher for solitary men and 30% higher for solitary women.

In this research, the scientists analyzed data from 473,648 participants aged 18 to 64 in the nationally representative National Health Interview Survey (NHIS) cohort in the United States. They collected information about the participants’ living arrangements and examined the relationship between living alone and cancer mortality.

In summary, 24% of the participants were living alone. Over a follow-up period of 22 years, a total of 8,729 cancer-related deaths were recorded, including 2,905 among those living alone and 5,824 among those living with others.

The study found that living alone increases the risk of cancer mortality by 32%. When the researchers conducted age-specific analyses, they discovered variations in cancer mortality risk. Among individuals aged 18-44, the risk of cancer-related death is 10% higher for those living alone. In the 45-54 age group, this risk increases to 31%, and among those aged 55-64, the risk rises to 38%.

Gender differences were also evident, with a 38% higher cancer mortality risk for solitary men and a 30% higher risk for solitary women.

Both men and women living alone have lower odds of survival

The researchers emphasized that the results of this study underscore the importance of addressing the issue of living alone and call for intervention measures to reduce the adverse effects of living alone and social isolation. They suggest that individuals living alone should undergo regular comprehensive screenings.

In conclusion, this nationally representative study highlights the increased risk of cancer mortality for adults living alone, emphasizing the importance of addressing this issue and further research to determine the potential mechanisms behind this association.
