Rhinitis is an independent risk factor for developing cough apart from colds among adults

Area of Science:

• Epidemiology
• Respiratory Medicine
• Clinical Research

Background:

• Cross-sectional studies suggest a strong link between rhinitis and chronic cough.
• Prospective and epidemiological data on this association are limited.

Purpose of the Study:

• To investigate the prospective association between rhinitis and the development of cough in a general adult population.
• To determine if rhinitis is an independent risk factor for incident cough.

Main Methods:

• Utilized data from the 'Pisa Prospective Study,' a population-based longitudinal cohort.
• Collected information on rhinitis, cough (chronic/occasional/any), and risk factors via standardized questionnaires.
• Followed 1670 adults without prior cough for approximately 5 years.

Main Results:

• Rhinitis at baseline was associated with a higher incidence of developing cough by follow-up (16% vs. 10%).
• Rhinitis remained a significant independent predictor for any cough (OR 1.8) and specific cough types (occasional and chronic).
• Adjusted odds ratios indicated increased risk for any cough (1.8), occasional cough (2.2), and chronic cough (1.7).

Conclusions:

• Rhinitis is a significant and independent risk factor for developing cough in adults.
• Findings highlight the need for further research into preventive strategies for cough in rhinitis patients.
