Results
Characteristics of participants to the study, questionnaires scores and nocturnal polygraphic results are reported in Table 1. The mean of the scores was lower than reference data in both HRQoL questionnaires [11,13]. A significant relationship was found between age and all questionnaires dimensions, except for PGWBI Anxiety and Vitality subscales (Table 2). Dividing the sample by gender, male subjects (n = 152) reported higher scores compared to females (n = 46) in PGWBI, except for Anxiety and Vitality subscales, and in both SF-12 summaries (Table 3). No differences were found in BMI, AHI, TSat90%, ESS and age between men and women.
