OBJECTIVE
Post COVID-19 condition is characterized by persistent symptoms after COVID-19 with yet unknown etiology. To explore whether media-related nocebo effects potentially contribute to post COVID-19 condition, we studied in an observational cohort whether frequencies of media coverage of symptoms after COVID-19 corresponded with prevalence rates of these symptoms in participants from a general population cohort diagnosed with COVID-19.
METHODS
Prevalence rates and typology of symptoms after COVID-19 in the general population (N = 4231), adjusted for prevalence rates in a matched non-infected control population (n = 8462) were calculated by using data on 23 symptoms from the Lifelines COVID-19 Cohort collected between March 2020 and August 2021. Media coverage of post COVID-19 condition was assessed by coding 1266 Dutch post COVID-19-related news articles (inter-rater-κ ≥ 0.75), published during the corresponding timeframe. Herein, we assessed whether the same 23 symptoms were mentioned as being related to post COVID-19 condition.
RESULTS
Core post COVID-19 condition symptoms were mentioned in 390 (30.8%) articles. Five of the ten core symptoms were mentioned by 10 or fewer articles. Ageusia/anosmia was most often persistently increased in COVID-19-positive participants (7.6%), yet was mentioned in 80 (6.3%) articles. General tiredness and breathing difficulties were frequently mentioned, in 23.9% and 17.1% of the articles respectively, while these were not the most frequently increased symptoms reported by participants (4.9% and 2.4%).
CONCLUSION
If post COVID-19 condition was predominantly attributable to nocebo effects, its symptom profile would be expected to reflect levels of media coverage for symptoms after COVID-19. However, our findings do not support this.
HIGHLIGHTS
• Media-related nocebo effects are suggested as cause for post COVID-19 condition.
• Nocebo explanations of somatic symptoms are frequently stigmatizing.
• Media coverage of symptoms does not correspond to rates of post COVID-19 symptoms.
• Our analysis does not support a potential nocebo effect in post COVID-19 condition.
