Abstract

Background

Socio-economic deprivation is well recognised as a risk factor for developing COVID-19. However, the impact of COVID-19 on economic vulnerability has not previously been characterised.

Objective

To determine whether COVID-19 has a significant impact on adequacy of household income to meet basic needs (primary outcome) and work absence due to sickness (secondary outcome), both at the onset of illness (acutely) and subsequently (long-term).

Design

Multivariate mixed regression analysis of self-reported data from monthly on-line questionnaires, completed 1st May 2020 to 28th October 2021, adjusting for baseline characteristics including age, sex, socioeconomic status and self-rated health.

Setting and Participants

Participants (n=16,910) were UK residents aged 16 years or over participating in a national longitudinal study of COVID-19 (COVIDENCE UK).

Results

Incident COVID-19 was independently associated with increased odds of participants reporting household income as being inadequate to meet their basic needs, both acutely (adjusted odds ratio [aOR) 1.39, 95% confidence interval [CI] 1.12 to 1.73) and in the long-term (aOR 1.15, 95% CI 1.00 to 1.33). Exploratory analysis revealed the long-term association to be restricted to those who reported ‘long COVID’, defined as the presence of symptoms lasting more than 4 weeks after the acute episode (aOR 1.39, 95% CI 1.10 to 1.77). Incident COVID-19 associated with increased odds of reporting sickness absence from work in the long-term (aOR 5.29, 95% CI 2.76 to 10.10) but not acutely (aOR 1.34, 95% CI 0.52 to 3.49).

Conclusions

We demonstrate an independent association between COVID-19 and increased risk of economic vulnerability, both acutely and in the long-term. Taking these findings together with pre-existing research showing that socio-economic disadvantage increases the risk of developing COVID-19, this may generate a ‘vicious cycle’ of impaired health and poor economic outcomes.

Summary Box

What is already known on this topic

  • Socioeconomic deprivation is recognised as a major risk factor for incidence and severity of COVID-19 disease, mediated via factors including increased occupational and household exposure to SARS-CoV-2 and greater physical vulnerability due to comorbidities

  • The potential for COVID-19 to act as a cause, rather than a consequence, of economic vulnerability has not previously been characterised.

What this study adds

  • We demonstrate an independent association between incident COVID-19 and subsequent self-report of household income being inadequate to meet basic needs, both acutely and in the long term

  • Incident COVID-19 was also associated with increased odds of subsequent self-report of sickness absence from work in the long-term.
