Assessing sexual functioning in patients with chronic disorders by using a generic health-related quality of life...

This study was an assessment of sexual functioning by making cross-sectional surveys of patients aged 45 84 years with chronic disorders; 397 had diabetes, 248 had glaucoma and 1914 had chronic, stable, angina pectoris; 1669 came from a standard population sample (SPS). Sexual functioning was assessed on one scale from the Swedish health-related quality of life survey (SWED-QUAL), adapted from the medical outcomes study (MOS). Both sexual functioning in general and specific sexual items were studied. Values were adjusted for non-respondents and standardised to the Swedish population. Response rates in the samples were 54-64% among men and 22-41% among women, decreasing with age for women. General sexual functioning decreased with age and was most apparent in patients with diabetes and angina pectoris, while glaucoma patients reported better results than the SPS. Loss of male erectile function was as common in diabetes (30%) as in angina pectoris (29%) and significantly higher than in the SPS (20%) (p < 0.001). Besides age, significant factors for erectile dysfunction were, in diabetes, the presence of microvascular complications, treatment with long-acting nitroglycerine and psychiatric disease, and in angina, the presence of diabetes and peripheral artery disease.
