Background:
Chronic rhinosinusitis (CRS) and allergic rhinitis are associated with functional limitations, but these impacts are not known on a population basis. Our objective was to epidemiologically determine functional limitations and workdays lost that are associated with CRS and allergic rhinitis in adults.
Methods:
The Medical Expenditure Panel Survey for calendar year 2007 was examined to identify cases of CRS and allergic rhinitis. Functional limitation variables for activity limitation, work limitation, social limitation, and cognitive limitation determined by the survey also were extracted. Using multivariate models adjusting for age, gender, race, ethnicity, education level, insurance status, geographic region, as well as the Charlson comorbidity index, incremental differences in workdays lost and these functional limitations were determined for patients with and without CRS and allergic rhinitis.
Results:
Among 225.1 million adults, the prevalences of CRS and allergic rhinitis were 4.9 ± 0.2% and 7.9 ± 0.3%, respectively. Patients with CRS demonstrated an incremental 1.04 ± 0.3 workdays lost per year along with significant increased adjusted odds ratios for activity limitation (odds ratio, 1.54), work limitation (1.50), and social limitation (1.49, all p < .005) but not cognitive limitation (1.05, p = .213). Patients with allergic rhinitis demonstrated an incremental 0.60 ± 0.45 workdays lost along with significant increased adjusted odds ratios for activity limitation (1.42), work limitation (1.43), social limitation (1.47), and cognitive limitation (1.32, all p < .019).
Conclusions:
Both CRS and allergic rhinitis impart significantly increased odds ratios for activity, work, and social limitations. Allergic rhinitis also carries with it statistically significant odds of functional cognitive limitation. The total aggregate workdays missed in the United States may be estimated at 11.5 million workdays and 10.7 million workdays for CRS and allergic rhinitis, respectively.

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,...

Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
