Lessons Learned-The Impact of the Third Wave of the COVID-19 Pandemic on German Waldorf Parents' Support Needs and Their Rating of Children's Health-Related Quality of Life: A Cross-Sectional Online Survey.

BACKGROUND: COVID-19-related lockdowns and homeschooling have imposed a substantial burden on school-aged children and parents. Waldorf education is a reform-educational concept. Little is known about the situation of German Waldorf families under pandemic conditions. METHODS: A cross-sectional, online, parent-proxy survey was conducted regarding the third pandemic wave. The primary outcome was parents' support needs, assessed with questions from the German COPSY (COVID-19 and PSYchological Health) study; the secondary outcome was children's HRQoL (KIDSCREEN-10, proxy version). RESULTS: We analyzed questionnaires from 431 parents of 511 Waldorf students aged 7 to 17 years. While 70.8% of Waldorf parents (WPs) reported a general need for support in dealing with their children, 59.9% of COPSY parents (CPs) indicated this need. WPs' support needs in dealing with their children's academic demands were similar to CPs' needs but relatively higher in terms of dealing with emotions and moods, behavior, and relationships within the family. WPs sought support mainly from school and teachers (65.6%). Support needs were high, although WPs rated their children's HRQoL higher than CPs. CONCLUSIONS: Our results underline the substantial pandemic-related burden on families across school types. WPs participating in this survey gave evidence that supports should focus on academic demands as well as psychosocial issues.

SARS-CoV-2 Seroprevalence Across a Diverse Cohort of Healthcare Workers

ImportanceAntibody testing is important for understanding patterns of exposure and potential immunity to SARS-CoV-2. Prior data on seroprevalence have been subject to variations in selection of individuals and nature as well as timing of testing in relation to exposures. ObjectiveWe sought to determine the extent of SARS-CoV-2 seroprevalance and the factors associated with seroprevelance across a diverse cohort of healthcare workers. DesignObservational cohort study of healthcare workers, including SARS-CoV-2 serology testing and participant questionaires. ParticipantsA diverse and unselected population of adults (n=6,062) employed in a multi-site healthcare delivery system located in Los Angeles County, including individuals with direct patient contact and others with non-patient-oriented work functions. ExposureExposure and infection with the SARS-CoV-2 virus, as determined by seropositivity. Main OutcomesUsing Bayesian and multi-variate analyses, we estimated seroprevalence and factors associated with seropositivity and antibody titers, including pre-existing demographic and clinical characteristics; potential Covid-19 illness related exposures; and, symptoms consistent with Covid-19 infection. ResultsWe observed a seroprevalence rate of 4.1%, with anosmia as the most prominently associated self-reported symptom in addition to fever, dry cough, anorexia, and myalgias. After adjusting for potential confounders, pre-existing medical conditions were not associated with antibody positivity. However, seroprevalence was associated with younger age, Hispanic ethnicity, and African-American race, as well as presence of either a personal or household member having a prior diagnosis of Covid-19. Importantly, African American race and Hispanic ethnicity were associated with antibody positivity even after adjusting for personal Covid-19 diagnosis status, suggesting the contribution of unmeasured structural or societally factors. Notably, number of people, or children, in the home was not associated with antibody positivity. Conclusion and RelevanceThe demographic factors associated with SARS-CoV-2 seroprevalence among our healthcare workers underscore the importance of exposure sources beyond the workplace. The size and diversity of our study population, combined with robust survey and modeling techniques, provide a vibrant picture of the demographic factors, exposures, and symptoms that can identify individuals with susceptibility as well as potential to mount an immune response to Covid-19. Key PointsO_ST_ABSQuestionC_ST_ABSWhat is the SARS-CoV-2 IgG seroprevalence rate across a large and diverse healthcare worker population, and which clinical, envionrmental, and symptom-based measures are associated with seropositivity? FindingsWe observed a seroprevalence rate of 4.1%. Adjusting for potential confounders, seropositivity was associated with younger age, Hispanic ethnicity, African-American race, and the symptom of anosmia, while not significantly associated with any pre-existing medical conditions. MeaningFactors associated with SARS-CoV-2 seroprevalence among our healthcare workers underscore the importance of exposure sources beyond the workplace.

SARS-CoV-2 Seroprevalence in Relation to Timing of Symptoms

Of individuals with SARS-CoV-2 IgG antibody testing performed, those who contemporaneously experienced a cluster of Covid-19 relevant symptoms in the 1-2 months preceding the antibody assay were more likely to test positive whereas those who experienced the symptom clustering in the prior 3-6 months were more likely to test negative. These findings suggest that antibodies likely wane over a period of months, particularly in relation to the timing of symptoms.
