The Relation Between @entity386 and XXXX in @entity1 with Severe Obstructive Sleep @entity386 : Mediational Effects of Sleep Quality.

@entity1 @entity308 @entity27 @entity25 @entity386
PURPOSE: We determined the relationship between @entity386 severity and @entity308 in a large sample of the newly diagnosed male @entity1 with @entity27 ( @entity27 ). METHODS: Data were collected from @entity1 who received polysomnography due to suspected @entity27 . The questionnaires included the Beck Depression Inventory (BDI), @entity25 ( @entity25 ), and Medical Outcomes Study (MOS)-Sleep Scale, for which Sleep Problems Index-1 (SPI-1) was calculated. The @entity27 index (AHI) and respiratory distress index (RDI) were used to measure @entity386 severity. The mediational model, which states that @entity27 severity affects @entity308 through a mediator, was tested here. RESULTS: In total, 302 male @entity1 with severe @entity27 participated. The mean @entity1 age was 48.4  years (SD  =  11.3  years). The BDI was >= 10 in 118 @entity1 (39  %) and was significantly associated with body mass index (r  =  0.114; p  =  0.048), @entity25 (r  =  0.164; p  =  0.004), SPI-1 (r  =  0.453; p  <  0.001), and RDI (r  =  0.126; p  =  0.029). According to the linear regression analyses, the RDI is not independently associated with the BDI. The strongest predictor of BDI was @entity25 (SPI-1; b  =  0.425; p  <  0.001). The bootstrap method confirmed that the depressive effects of RDI are significantly mediated by poor @entity25 (bootstrapped 95  % CI 0.0113-0.0632). CONCLUSIONS: There is evidence of a mediational role of subjective @entity25 on the relationship between @entity386 severity and @entity308 in male @entity1 with severe @entity27 .
