Abstract
Background: Post COVID-19 syndrome has emerged as a long-term
complication in adults and children, its effect on adolescents’
performance in school is not well studied.
Methods : This is a survey of children in grades 10-12 looking
into the physical/psychological impact of prolonged post COVID-19
symptoms on school performance.
Results: 32/54 students with a mean age of 16 years old had
COVID-19. Two were hospitalized, 10 had symptoms lasting more than 4
weeks. Commonly reported chronic symptoms were fatigue and cough. Seven
students quit sports, 8 had decrease in their academic performance.
Adolescents with a family history of long haulers and those being
infected more than once where more likely to develop prolonged symptoms,
quit sports and perform poorly in school. 3/14 (21%) reported not
seeking help.
Conclusion : Post COVID-19 syndrome is associated with decline
in physical and mental performance in school yet only 79% of
adolescents will talk about it.
Introduction
Coronavirus disease 2019 (COVID-19), has been associated with
significant worldwide morbidity and mortality (1). The understanding of
the long-term effects of COVID-19 (post-acute COVID-19 syndrome) is
still evolving. The residual effects of severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2) infection includes fatigue, dyspnea,
chest pain, cognitive disturbances, and arthralgia (2). A study of 183
adults in the United States (3) showed that fatigue, dyspnea and
psychological distress, were present in approximately 30%, 35 days post
discharge. The severity of the acute illness was shown to be associated
with persistence of symptoms (2). The definition of the post-acute
COVID-19 has been suggested to include persistence of symptoms beyond 3
or 4 weeks from the initial infection (4). Until recently published data
on the prolonged effect of COVID-19 in children has been limited to
multisystem inflammatory syndrome (5). Persistence of post infectious
symptoms beyond 4 weeks in children has been reported (6), however the
impact on school performance was not.
Our pilot study’s main objective
was to look at the physical/psychological impact of post-acute COVID-19
on children’s school performance. Secondary objectives included looking
for correlation between prolonged symptoms and age, race, blood type,
SARS-Cov 2 variant, severity of initial infection, first or second
infection and presence of a family history of prolonged symptoms.
Methodology and statistical analysis
This was a cross sectional pilot study at one high school. The protocol
were approved by our Institutional Review Board (IRB). A web-based
(fully anonymized) survey using Google Forms was used. The survey link
was shared with the students with the help of their teachers over a
period of 2 weeks (5/13/2022-5/30/2022). Participation was voluntary.
The fully anonymized data was obtained from Google Forms was analyzed
using SPSS software version 27.
Results
We surveyed 54 students, 15 to 18 years-old, 32 females, 45 White, 9
belonging to minority groups. 9 students were not fully vaccinated (no
vaccination or only one dose of an mRNA vaccine). 32 (59.3%) reported
having had COVID-19 and 7/32 (21.8%) were infected more than once. 21
had COVID-19 between December 2021 and May 2022 during the surge of the
Omicron variant (BA1), and 12 between April 2020 and May 2021. Two
(6.2%) students were hospitalized. 14 students had COVID-19 despite
being fully vaccinated. Most common acute symptoms were fatigue,
headaches and fever.
While many reported a short illness, 10 (31.3%) students reported
symptoms for more than 4 weeks (2 students from 6 to 9 months). Of the
10 students with prolonged symptoms 60% were fully vaccinated and 60%
had COVID-19 during the Omicron surge. The symptoms lasting more than 4
weeks included fatigue or cough in 30%, dyspnea or depression/anxiety
in 20%, difficulty concentrating, headaches, loss of smell or taste and
myalgia/arthralgia in 10%. Half of the children with symptoms lasting
more than 4 weeks (long haulers) had symptoms persist after the first
COVD-19 while the other half had prolonged symptoms after subsequent
infections. 6/38 (15.8%) students reported that one of their family
member was a long hauler. 7/30 (23.3%) quit sports for the season. 8/30
(26.6%) had decrease in their academic performance with worsening
grades following COVID-19. Factors found to be associated with prolonged
symptoms included having a family member with prolonged symptoms and
having had COVID-19 more than once. Long haulers were found to be more
likely to quit sport and have a decline in school grades (Table1). Using
a visual scale (from 1 to 10) to describe their health many students who
had COVID-19 reported some form of deterioration of their perceived
general health status (figure1).
Discussion
Our study is a pilot study based on a survey to reach a large number of
students in a short period of time while maintaining anonymity. This
study involves a specific age and setting that is understudied. In a
previous survey by the world health organization, the study showed a
significant impact of the COVID-19 pandemic on school aged children,
their mental health and their performance in school in a general sense
but not the impact of the infection itself and associated factors (7).
In our study, 16 % of students were unvaccinated. While being
unvaccinated was not statistically associated with developing prolonged
symptoms that lasts more than 4 weeks, there was a trend toward
significance (p 0.07). This is likely related to the small sample size
of this study. Having COVID-19 more than once was significantly
associated with prolonged symptoms. The underlying pathophysiology
remains unclear. The association we found between having a long hauler
family member and increased risk of developing prolonged symptoms may
suggest a common underlying hereditary trait that may be shared among
certain family members and triggered by COVID-19. Unlike the study by
Raos et al that showed correlation between outcome and admission to the
intensive care unit during the acute illness phase and post-acute
COVID-19 (6), our study did not. Other studies also showed correlation
between outcome and race (8) blood type (9) and infecting variant type
(10) while ours did not and this is likely due to the small number of
studied subjects.
Despite the fact that the COVID-19 pandemic affected the wellbeing of
many children whether infected or not, the effect on those who develop
prolonged symptoms seems to be far greater than the other groups. More
kids in this group quit sports for the season and had a worse decline in
their academic grades compared to their peers, which warrants special
attention. Race or sex or smoking/vaping were not shown to have a
significant effect in this age group. In this study 3/14 (21%) of
participants have not sought medical attention which should not be taken
lightly. The most common prolonged symptoms reported were fatigue, cough
and central nervous system/mental disorder. Parents, teachers and health
care providers should be aware of the significant impact of post-acute
COVID-19 on children with prolonged symptoms, warranting an early
screening and intervention in a timely manner to maintain their kids’
wellbeing.
Conclusion
Having had recurrent COVID-19 infections or a family history of long
haulers appears to be associated with post-acute COVID-19 syndrome.
Adolescents whose symptoms last more than 4 weeks are most affected with
an increased risk of decline in their academic and physical wellbeing.
