Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The aim of the present study will be to evaluate in conscripts at the military induction board the prevalence of rhinosinusitis, the prevalence of HPV vaccinations, the prevalence of hearing impairments and the prevalence of long-COVID symptoms and further, to evaluate different factors that influence on the one hand the prevalence (urban-bred, non-urban-bred) and on the other hand symptoms (ENT-surgeries in medical history). Further, we want to evaluate if there is a correlation between subjective symptoms and apparated-based diagnostic investigations.

Therefore, questionnaires and data of medical examinations, aquired routinely at the military induction board, will be analysed.

Read the detailed description

Rhinosinusitis is a very common complaint at ENT departments, whereby symptoms of the underlying disease are varying. Therefore, there is growing interest in prevalence of rhinosinusitis including differences in prevalence's depending on where the patient grew up. Further, there is growing interest in answering the question if different factors, including ENT-surgeries in medical history have an impact on symptoms of rhinosinusitis.

Within the past few years there is growing interest in carring out as many HPV-vaccinations as possible in order to reduce the prevalence of HPV-associated cancers.

Further, in adolescents there is a growing number of hearing impairments, including hearing loss and/or sounds in the ears.

Next, since the beginning of the COVID pandemic there are very common complaints in adult and pediatric patients about persistent medical problems for weeks or months after an acute SARS-CoV-2-infection and cannot be explained by another diagnosis, called long- Covid disease.

The military induction board of conscripts enables access to data from a cross-section of the population, with common characteristics of gender and age.

In the present study we want therefore to evaluate in conscripts at the military induction board the prevalence of rhinosinusitis, the prevalence of HPV vaccinations, the prevalence of hearing impairments and the prevalence of long-COVID symptoms and further, to evaluate different factors that influence on the one hand the prevalence (urban-bred, non-urban-bred) and on the other hand symptoms (ENT-surgeries in medical history). Further, we want to evaluate if there is a correlation between subjective symptoms and apparated-based diagnostic investigations.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Dec 2023; primary completion for Dec 2025, 24 months later.

Of 22 observational studies under Rhinosinusitis, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 71. This study's planned 24 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 27, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
