Abstract

Objective

This study aimed to compare the relative physical recovery and symptoms after SARS-CoV-2 infection between groups confirmed positive or negative to early strains of COVID-19.

Methods

A prospective, longitudinal cohort study compared outcomes of metropolitan adults polymerase chain reaction-tested for COVID-19 between March and November 2020 in Western Australia. Control matching was attempted: inpatients (gender, age) and ambulatory clinic (gender, age, asthma, chronic pulmonary disease). One-year follow-up involved three repeated measures: physical function (grip strength and 1-min sit-to-stand) and patient-reported outcomes (Fatigue Severity Scale, modified Medical Research Council dyspnoea scale and Euroqol-5D-5L).

Results

Three hundred and forty-four participants were recruited (154 COVID+, age 54 ± 18 years, 75 females [49%]); 190 COVID−, age 52 ± 16 years, 67 females [35%]) prior to national vaccination roll-out. No between-group differences in physical function measures were evident at any time point. Fatigue (OR 6.62, 95% CI 2.74–15.97) and dyspnoea (OR 2.21, 95% CI 1.14–4.30) were higher in the COVID+ group at second assessment (T2). On Euroqol-5D-5L, no between-group differences were evident in the physical function domains of self-care, mobility or usual activities at any time point. However, COVID+ participants were less likely to report an absence of anxiety or depression symptoms at T2 (OR 0.41, 95% CI 0.19–0.89).

Conclusions

Neither statistical nor clinically meaningful differences in physical function were evident between COVID+ and COVID− participants to 12-months after acute illness. Symptoms of fatigue, dyspnoea, anxiety or depression were more prevalent in the COVID+ group til ~8 months after illness with between-group differences no longer evident at 1 year.

Keywords: anxiety, control group, COVID-19 virus infection, depression, dyspnoea, fatigue, pain, primary care, quality of life.
