Summary
Difficulty chewing is linked to a higher risk of chronic cough in Korean adults. This finding suggests a connection between oral health and respiratory symptoms, warranting further investigation.
Area of Science:
- Oral health and respiratory medicine
- Epidemiology of chronic diseases
Background:
- Chronic cough is a prevalent symptom with diverse causes, including upper airway cough syndrome, asthma, and gastroesophageal reflux.
- Emerging research highlights a potential connection between dental conditions and respiratory ailments.
Purpose of the Study:
- To investigate the association between masticatory difficulty and the prevalence of chronic cough.
- Utilizing data from the Korean National Health and Nutrition Examination Survey (KNHANES) spanning 2011-2015.
Main Methods:
- Analysis of 9706 participants from the KNHANES dataset.
- Self-reported data on masticatory function and chronic cough.
- Statistical analysis using binary and multiple logistic regression, controlling for covariates like age, sex, socioeconomic status, lifestyle, and laboratory markers.
Main Results:
- Masticatory difficulty was reported by 32.2% of participants.
- The prevalence of chronic cough was higher in individuals with masticatory difficulty (4.8%) compared to those without (3.0%).
- Adjusted analysis revealed a significant association between masticatory difficulty and increased chronic cough prevalence (OR, 1.137; 95% CI, 1.134-1.140).
Conclusions:
- Masticatory difficulty is associated with an elevated risk of chronic cough in the Korean adult population.
- Further research, including prospective and microbiological studies, is needed to understand the mechanisms linking mastication and respiratory health.
- Masticatory difficulty may serve as a clinical indicator for chronic cough, emphasizing the need for interdisciplinary collaboration between dental and respiratory professionals.

Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
