Impact of loneliness on health-related factors in Australia during the COVID-19 pandemic: A retrospective study.

Abstract

COVID‐19 pandemic and its associated social and physical distancing restrictions may have had a severe impact on health. In the present study, we investigate the changes in physical, social and mental health, as well as the health literacy of Australians subsequent to the onset of COVID‐19 pandemic, and examine the influence of loneliness on these health‐related factors. Using a retrospective cross‐sectional study design, 607 Australian adults completed a self‐report online survey which assessed their health‐related factors before and after onset of the COVID‐19 pandemic (data collected between June 2020 to November 2020). Australians reported statistically significant increase in a number of (poorer) health‐related factors (e.g., weight gain, sleeping difficulties, poor somatic health, higher loneliness, more issues navigating the healthcare system) post onset of COVID‐19 pandemic. Further, after adjusting for covariates, higher loneliness during pandemic predicted poorer health‐related outcomes (e.g., more somatic health complaints, poorer quality of diet, poorer social support for health). The COVID‐19 pandemic and its associated social and physical distancing restrictions may have contributed towards poorer health‐related factors among Australian adults. Further, increased loneliness during the pandemic may have further worsened physical health and health literacy outcomes among Australians.
