However, the underlying mechanisms, and their role in prolonged post-COVID-19 symptoms (long COVID), remains unclear. To find out more, researchers looked for associations between a range of clinical characteristics measured before the pandemic--HbA1c (average blood sugar level), self-reported or medication-based diabetes, body mass index (BMI) and waist-to-hip ratio (WHR)--and self-reported COVID-19 infection and long COVID in nine ongoing UK cohort studies.

All eligible participants (maximum 31,252, aged 19-75 years old, 57% female) had data on previous measurements and completed at least one questionnaire during the COVID-19 pandemic (May 2020 to September 2021) covering questions on COVID-19 and, where possible, questions on the length of ongoing COVID-19-related symptoms.
