Associations between cancer history, social distancing behaviors, and loneliness in adults during the COVID-19 pandemic.

BACKGROUND

During the COVID-19 pandemic, enforced social distancing initiatives have highlighted differences in social distancing practices and the resulting loneliness in various populations. The objective of this study was to examine how cancer history and social distancing practices relate to loneliness during COVID-19.

METHODS AND FINDINGS

Participants from previous studies (N = 32,989) with permission to be re-contacted were invited to complete a survey online, by phone, or by mail between June and November 2020. Linear and logistic regression models were used to determine the associations between cancer history, social distancing, and loneliness.

RESULTS

Among the included participants (n = 5729), the average age was 56.7 years, 35.6% were male, 89.4% were White, and 54.9% had a cancer history (n = 3147). Individuals with a cancer history were more likely to not contact people outside of their household (49.0% vs. 41.9%, p<0.01), but were less likely to feel lonely (35.8% vs. 45.3%, p<0.0001) compared to those without a cancer history. Higher adherence to social distancing behaviors was associated with higher odds of loneliness among individuals with (OR = 1.27, 95% CI: 1.17-1.38) and without a cancer history (OR = 1.15, 95% CI: 1.06-1.25).

CONCLUSIONS

Findings from this study can inform efforts to support the mental health of individuals susceptible to loneliness during the COVID-19 pandemic.
