Introduction: Healthcare-seeking behaviour may change over time, and some groups are more likely to avoid relevant help seeking, which possibly contributes to social inequity in health. Thus, we developed an expansion of and follow-up to the Danish Symptom Cohort (DaSC) from 2012 and formed the DaSC II, which encompassed a population-based questionnaire study investigating symptoms and healthcare-seeking behaviour. In this paper, we describe the conceptual framework, development and content validity of the questionnaire and a responder analysis of the participants in the DaSC II. We present the symptom iceberg in the Danish general population by estimating the prevalence of symptoms and proportion of contacts to general practitioners (GPs) in 2022. Moreover, we discuss differences in healthcare-seeking behaviour with reference to the 2012 DaSC. Methods: 100,000 randomly selected Danish citizens aged ≥20 years, along with the 44,713 respondents from the 2012 cohort, were invited to participate in a survey. The questionnaire was pilot and field tested prior to distribution. Descriptive statistics were used to estimate symptom prevalence and proportion of GP contacts, and to execute the respondent analysis. Results: Nine out of ten respondents reported at least one symptom within the preceding four weeks and reported an average of 4.6 symptoms. One in four symptoms were presented to a GP. The highest proportion of GP contacts was found for haematuria (63.3 %) and shortness of breath (51.8 %). For several symptoms, differences between the sexes were found in relation to both prevalence and GP contacts. The proportion of GP contacts was higher in 2022 than in 2012 and was most pronounced for general, frequently experienced symptoms and to a lesser extent for cancer alarm symptoms. Conclusion: Many symptoms go unreported, which may delay relevant diagnosis; more research on certain symptom categories and population subgroups is needed. Future studies based on the DaSC II form a basis for interventions targeting symptom awareness, healthcare-seeking behaviour and social equity in society and health.
