Risk factors of post-COVID-19 symptoms

Risk factors of post-COVID-19 symptoms, a cross-sectional study in patients with asthma and chronic obstructive lung disease. Download PDF Abstract Post-COVID-19 symptoms are common following COVID-19, but risk factors of persistent symptoms in patients with asthma and chronic obstructive lung disease (COPD) remain unclear. In this cross-sectional study, we used data from the Swedish PRAXIS study collected in 2022.

The cohort included randomly selected adult patients with a diagnosis of asthma or COPD in medical records from central Sweden’s primary and secondary care. Participants completed a comprehensive questionnaire, and their responses were analysed. We used logistic regression and adjusted for age and lung disease diagnoses.

Among 494 patients with confirmed COVID-19, 59% (289/494) reported post-COVID-19 symptoms. Risk factors for post-COVID-19 symptoms included severe acute infection (adjusted odds ratio aOR: 8.91, 95% confidence interval [CI]: 3.49–22.8), higher age (aOR:1.25, 95% CI: 1.09–1.45), female sex (aOR: 1.52, 95% CI: 1.04–2.21), and obesity [BMI ≥ 30] (aOR: 2.24, 95% CI: 1.44–3.47)).
