Deaths involving COVID-19 by disability status: a retrospective analysis of 29 million adults during the first two waves of the Coronavirus pandemic in England
Abstract
Objectives
To assess the association between self-reported disability and deaths involving COVID-19 among adults in England.
Design
Cohort study of >29 million adults using data from the Office for National Statistics Public Health Data Asset.
Setting
People living in private households or communal establishments (including care homes) in England.
Participants
29,293,845 adults (47% male) aged 30-100 years (mean age = 56) present at the 2011 Census who were alive on 24 January 2020. The main exposure was self-reported disability from the 2011 Census.
Main outcome measures
Death involving COVID-19, occurring between 24 January 2020 and 28 February 2021. We estimated the age-standardised mortality rate per 100,000 person-years at-risk, stratified by sex, disability status, and wave of the pandemic. We calculated hazard ratios (HRs) for disabled people compared with non-disabled people, adjusted for geographical factors, socio-demographic characteristics, and pre-pandemic health conditions.
Results
Disabled people made up 17% of the study population, including 7% who were ‘more-disabled’ and 10% ‘less-disabled’. From 24 January 2020 to 28 February 2021, 105,213 people died from causes involving COVID-19 in England, 58% of whom were disabled. Age-adjusted analyses showed that, compared to non-disabled people, mortality involving COVID-19 was higher among both more-disabled people (HR=3.05, 95% CI: 2.98 to 3.11 in males; 3.48, 3.41 to 3.56 in females) and less-disabled people (HR=1.88, 95% CI: 1.84 to 1.92 in males; 2.03, 1.98 to 2.08 in females). Among people aged 30-69, HRs reached 8.47 (8.01 to 8.95) among more-disabled females and 5.42 (5.18 to 5.68) for more-disabled males. Sequential adjustment for residence type, geography, socio-demographics, and health conditions partly explained the associations, indicating that a combination of these factors contributed towards the increased risk.
Conclusion
Disabled people in England had markedly increased risk of mortality involving COVID-19 compared to non-disabled people and should be prioritised within the pandemic response.
