[Post-COVID-19 condition in children and adolescents from a cohort: prevalence and risk factors].

Abstract

Objective: To determine the prevalence and risk factors of the post-COVID-19 condition of children and adolescents from a cohort.

Methods: Observational and analytical cohort study. Statistical analysis: percentages, frequencies; averages; Odds ratio, χ² test, and multiple binary logistic regression. Statistical Package, for the Social Sciences 23.

Results: Prevalence of the post-COVID-19 condition was: 14.8% of 175 patients who fulfilled the inclusion criteria, 26 developed post-COVID-19 condition, mean age 5.9 years (SD: 5.05), sex: 27% men, 73% women, frequent symptoms: fatigue, runny nose, muscle pain, dyspnea. Symptoms associated with post-COVID-19 condition: muscle pain (OR: 27; p = 0.000; IC95%5.2-139), dysgeusia (OR: 19; p = 0.012; IC95%: 1.9-19), and fatigue (OR: 5; p = 0.001; IC95%: 1.9-13.5). Associated risk factors: female (OR: 3.58; p = 0.023; CI95%: 1.19-10.71), comorbidities (OR: 24.5; p = 0.000; CI95%: 7.52-79), allergic rhinitis (OR: 8.7; p = 0.000; CI95%: 2.66-28.87), atopic dermatitis (OR: 9. 58; p = 0.016 CI95%: 1.51-60.5).

Conclusions: Although the majority of children infected with SARS-CoV-2 recover completely, some of them will develop a post-COVID-19 condition, knowing the most frequent symptoms and associated factors, will allow a better evaluation, for its opportune detection and effective treatment.
