Objectives: The aim of this study was to investigate the prevalence of erectile dysfunction, its severity, and other sexual function domains in hypertensive and normotensive Qatari's men and to estimate the association between hypertension and predictors of erectile dysfunction.
Material and methods: A matched case-control study was conducted at the primary health care clinics during a period from May to October 2006. Four hundred twenty-five hypertensive patients and 425 age-matched normotensive attendants of primary health care clinics, aged 30-75 years, were approached for the study. Of them, 296 hypertensive participants (74%) and 298 normotensive men (70.1%) gave their consent to participate in it. The mean age of the hypertensive participants was 54.8+/-11.5 years as compared to nonhypertensive participants with a mean age of 54.5+/-12.1 years. Face-to-face interviews were based on a questionnaire that included variables on age, sociodemographic status, educational level, occupation, cigarette smoking, and blood pressure. Hypertension was defined as mild for systolic blood pressure (SBP) 120-139 mmHg and diastolic blood pressure (DBP) 80-89 mmHg; moderate for SBP 140-159 mmHg and DBP 90-99 mmHg; and severe for SBP >160 mmHg and DBP >100 mmHg. All patients completed a detailed questionnaire addressing their general medical history, with special emphasis on hypertension (i.e., duration of hypertension, type of treatment, and presence of any complications). Sexual function was evaluated with the International Index of Erectile Function (IIEF).
Results: Of the 296 hypertensive patients, 196 participants reported erectile dysfunction (66.2%), while among the 298 nonhypertensive participants, only 71 had erectile dysfunction (23.8%). Of the hypertensive participants studied, 25% had severe, 29.1% had moderate, and 12.1% had mild erectile dysfunction. The percentages of various sexual activity domains were highly significant and at higher risk among hypertensive patients than normotensive men (P<0.001). Frequency and severity of erectile dysfunction increased with advancing age.
Conclusions: Our results have shown that the prevalence of erectile dysfunction was significantly higher in Qatari hypertensive men than in normotensive men. Age, level of education, diabetes mellitus, occupation, and duration of hypertension were considered statistically significant predictors of erectile dysfunction. Erectile dysfunction was more common in hypertensive individuals receiving antihypertensive treatment.
