RÉSUMÉ
Introduction: We investigated the relationship between knowledge of the common cold and desire for medical treatment.Methods: We administered an anonymous self-questionnaire about the common cold to citizens receiving health checkups in City X, Ibaraki Prefecture, between August and September 2012. We assessed citizens' knowledge about the common cold and whether they sought medical treatment for it, in addition to their demographic attributes.Results: We included 1079 citizens (response rate, 74.5%) in the analysis. The majority of participants believed that receiving intravenous (IV) infusions or injections for the common cold led to faster recovery times (75.9%). Roughly half of the participants (42.0%) did not believe that antibiotics are not effective against virus-based colds, while 28.6% were unsure. Finally, endorsement of the questionnaire items "taking cold medications early leads to faster recovery" (OR: 1.61) and "IV infusions or injections lead to faster recovery times" (OR: 1.86) were associated with a desire for medical treatment.Conclusion: Our results indicate that patients' knowledge about the common cold and their understanding of treatment options available at medical institutions were inadequate. Furthermore, we found that an awareness of how cold medicines, IV infusions, or injections may shorten treatment duration was associated with a desire for treatment.
