Brief Summary
We aimed to investigate the relationship between obstructive sleep apnea (OSA) risk and respiratory inflammation evaluated by the exhaled breath condensate (EBC)interleukin-6 IL-6 and plasma SP-D, based on the Berlin questionnaire (BQ) screening values in an adult, urban community in Beijing, China. Volunteers aged \>40 years were recruited from the Shichahai community of central Beijing. Their general information and disease history were recorded. OSA risk was assessed using the BQ. IL-6 in EBC and plasma SP-D were detected by enzyme-linked immunoassay (ELISA)through specimens collected on fasting. The differences in IL-6 and SP-D contents between high-risk and low-risk groups for OSA were compared, and the factors affecting their contents were analyzed.

Outcome Measures
Primary Outcomes (1)
Correlation between risk for OSA and inflammation
The levels of EBC IL-6 and plasma SP-D were detected by ELISA. The levels of EBC IL-6 and plasma SP-D between the high- and low-OSA risk groups were compared.
through study completion, an average of 3 year
Secondary Outcomes (1)
Comorbidities, inflammation and risk of sleep apnea
through study completion, an average of 3 year
Study Arms (2)
the low-risk group for OSA
A Chinese translation of the BQ was used to classify subjects into high risk and low risk for OSA.
the high-risk group for OSA
A Chinese translation of the BQ was used to classify subjects into high risk and low risk for OSA.
Eligibility Criteria
The volunteers were recruited residents from the Shi Cha Hai community of Beijing, China.
