Relationships Between Health-Related Quality of Life and Social Support in Patients with Obstructive Sleep Apnea-Hypopnea Syndrome / 中国呼吸与危重监护杂志

ABSTRACT

Objective To study the relationships among health-related quality of life(HRQL), social support, excessive daytime sleepiness (EDS) and PSG parameters in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods Eighty-five patients were recruited who were diagnosed as OSAHS by overnight po]ysomnography from August 2007 through November 2007 in West China Hospital.The Calgary sleep apnea quality of life index (SAQLI) was used for HRQL, social support rating scale (SSRS) was used for social support,and Epworth sleepiness scale(ESS) was used for EDS.The Pearson linear correlation and stepwise multiple regression analysis were used to analyze the correlation among SAQLI, SSRS, ESS, and PSG.Results The SAQLI was correlated with SSRS score (r = 0.402, P < 0.01) ; ESS score (r =-0.505 ,P <0.01) ; apnea-hypopnea index (AHI) (r =-0.269,P <0.05) and lowest artery oxygen saturation (ISaO2) (r = 0.226, P < 0.05).Stepwise muhiple regression analysis determined two variables,the SSRS and ESS score,as independent factors for predicting the total score of SAQLI which accounted for 37.3% of the total variance in the total score on SAQLI (R2 = 0.373, P < 0.001).Conclusions The HRQL of patients with OSAHS was correlated with the SSRS score, ESS score and PSG parameters.The former two were the more important factors to affect the HRQL of patients with OSAHS.
