A considerable number of individuals infected with SARS-CoV-2 continue to experience symptoms after the acute phase. Here, we report findings from a nationwide questionnaire study in Denmark including 61,002 RT-PCR confirmed cases and 91,878 test-negative controls aged 15-years or older. Six twelve months test, risks 18 out 21 were elevated among test-positives. The largest adjusted risk differences (RD) observed for dysosmia (RD = 10.92%, 95% CI 10.68-11.21%), dysgeusia 8.68%, 8.43-8.93%),...
Abstract Postacute symptoms are not uncommon after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with pre-Omicron variants. How the Omicron variant and disease 2019 (COVID-19) booster vaccination influence risk of postacute is less clear. We analyzed data from a nationwide Danish questionnaire study, EFTER-COVID, comprising 36 109 individuals aged ≥15 years who were tested between July 2021 January 2022, to evaluate associations COVID-19 new-onset general health...
Exposure to radiofrequency electromagnetic fields (RF-EMF) from mobile communication technologies is changing rapidly. To characterize sources and associated variability, we studied the differences correlations in exposure patterns between children aged 8 18 their parents, over course of day, by age, activity pattern, for different metrics exposure.Using portable RF-EMF measurement devices, collected simultaneous real-time personal measurements 24 72 h 294 parent-child pairs Denmark,...
Abstract Background A considerable number of individuals infected with SARS-CoV-2 continue to experience symptoms after the acute phase. More information on duration and prevalence these in non-hospitalized populations is needed. Methods We conducted a nationwide cross-sectional study including 152 880 aged 15-years or older, consisting RT-PCR confirmed cases between September 2020-April 2021 (N=61 002) corresponding test-negative control group (N=91 878). Data were collected 6, 9 12 months...
It is not well-described how the acute symptoms of infection with severe respiratory syndrome coronavirus 2 (SARS-CoV-2) differ by variant, vaccination, sex and age. A cross-sectional questionnaire study linked to national testing- registry data was conducted among 148,874 SARS-CoV-2 first time reverse transcription polymerase chain reaction (RT-PCR) test-positive individuals corresponding date-matched symptomatic test-negative controls. Major variants (Index/wild type, Alpha, Delta Omicron)...
Background Few cost-effective strategies to shift dietary habits of populations in a healthier direction have been identified. We examined if participating chatbot health education program transmitted by Short Messages Service (“SMS-program”) could improve adolescent behaviors and body weight trajectories. also explored possible added effects maternal or peer involvement. Methods findings conducted randomized controlled trial (RCT) among adolescents from the Danish National Birth Cohort...

Abstract Many individuals who refuse COVID-19 vaccination have concerns about long-term side effects. Here, we report findings on self-reported symptoms from a Danish survey- and register study. The study included 34,868 vaccinated primary course recipients, 95.8% of whom received mRNA vaccines, 1,568 unvaccinated individuals. Participants had no known history SARS-CoV-2 infection. Using g-computation logistic regression, risk differences (RDs) for between persons were estimated with...
Abstract Background Longitudinal cohort studies are pivotal to understand how socioeconomic, environmental, biological, and lifestyle factors influence health disease. The added value of increases as they accumulate life course data expand across generations. Ensuring that participants stay motivated contribute over decades follow-up is, however, challenging. Participant engagement involvement (PEI) aims secure the long-term commitment promote researcher-participant interaction. This study...
Background: It is not well-described how the acute symptoms of infection with SARS-CoV-2 differ by virus variants and vaccination. In current study, we describe variant vaccination status in DenmarkMethods: A nationwide questionnaire study including 148,874 first time reverse transcription polymerase chain reaction (RT-PCR) test-positive individuals corresponding date-matched symptomatic test-negative controls were conducted. Major (Index, Alpha, Delta Omicron) defined using periods...
<h3>Background/aim</h3> Exposure to radiofrequency electromagnetic fields (RF-EMF) has rapidly increased and little is known about exposure levels in children. This study aims describe personal RF-EMF environmental from handheld devices fixed site transmitters European children its day-to-day year-to-year repeatability. <h3>Methods</h3> Environmental (µW/m<sup>2</sup>) was measured 529 (ages 8–18) Denmark, the Netherlands, Slovenia, Switzerland, Spain using portable metres over 3 days...
Background: Many individuals who choose not to receive COVID-19 vaccines have concerns about long-term side effects. These also encompass psychiatric, cognitive, fatigue, and physical symptoms easily captured in routine healthcare settings. To further ensure safety increase public confidence vaccines, more information the risk of effects following vaccination is needed. In this study, we investigated longer term primary course Covid-19 vaccines.Methods: Completed questionnaires (response...
