Loneliness among adolescents and young adults with cancer during the COVID-19 pandemic: a cross-sectional survey

Background Adolescents and young adults (AYAs) diagnosed with cancer are at an increased risk of experiencing social isolation and loneliness secondary to their cancer and its treatment. The physical distancing measures implemented during the COVID-19 pandemic may have further increased loneliness among this group. This study examined the prevalence of loneliness and factors associated with loneliness among AYAs with cancer during this pandemic. Methods We conducted a self-administered, online, cross-sectional survey of Canadian AYAs diagnosed with cancer between 15 and 39 between January and February 2021. Loneliness was measured using the 3-item UCLA Loneliness Scale. Factors associated with higher levels of loneliness were identified using multiple logistic regression. Results The analysis included 805 AYAs. The prevalence of loneliness was 52.2% [N = 419, 95% CI (confidence interval) 48.7 to 55.6%]. Individuals who were 18–25 years old [AOR (adjusted odds ratio)1.60, CI 1.03–2.47, p = 0.035], currently undergoing cancer therapy (AOR 1.46, 95% CI 1.03–2.07, p = 0.035), who self-disclosed the presence of a pre-pandemic mental health condition (AOR 2.09, 95% CI = 1.22–3.58, p = 0.007), or were not in a relationship (AOR 2.22, 95% CI 1.57–3.14, p
