The prevalence of bother, acceptance, and need for help in men with erectile dysfunction.

INTRODUCTION: Apart from knowledge on the prevalence of erectile dysfunction (ED), for clinical reasons it is important to obtain information on concern or bother and need for help. However, information is lacking on men with ED who need help but do not seek medical attention. Thus, this study aimed to assess the distribution of bother, acceptance, and need for help in men with ED, and assess characteristics of patients with ED in need for help but not receiving medical attention for ED. METHODS: A total of 5,721 men aged 18 years and older and registered in 12 general practices in the middle of the Netherlands were sent a questionnaire by mail about sexual problems, ED, need for help, and medical attention. Out of 2,117 questionnaires that were returned, 1,481 were completed on ED, bother, and need for help. RESULTS: The prevalence of ED (according to World Health Organization definition) in the 1,481 men was 14.2%. Of these men 67.3% were bothered, 68.7% did not accept ED, and 85.3% wanted help. Surprisingly, 41.9% of men who denied a need for help were bothered and 19.4% did not accept ED. Only 10.4% of men with ED received any medical care. Bother in men with ED was related to increasing age (decreasing above 60 years). Compared with men who already received help for ED, men who wanted help but did not receive it more often suffered from diabetes, neurological problems, and various cardiovascular problems. On the other hand, history of myocardial infarction increased the chance of getting adequate medical attention for ED. CONCLUSIONS: The majority of men with ED are concerned or bothered and perceive a need for help. Most of them do not receive any medical attention. These men are characterized by chronic medical conditions, visiting the physician's office regularly for their medical condition.

Impact of various questionnaires on the prevalence of erectile dysfunction. The ENIGMA-study.

The prevalence estimates of erectile dysfunction (ED) vary considerably across studies. These differences may be attributed to used definitions of ED. Quantitative data on the effect of different definitions of ED on the prevalence are lacking, because precise information on the used definition and questionnaire is often absent. Aim of this study was to quantify the effect of using different questionnaires for ED on the prevalence estimates. In all, 5721 mail surveys on sexual problems and ED were sent to all men (aged >18 y) in 12 general practices in the middle of the Netherlands of which 2117 were completed. The questionnaire contained Enigma (WHO), International Index of Erectile Function (IIEF), Cologne Erectile Inventory (KEED) and one question (Boxmeer, Krimpen). The prevalence of ED based on the various questionnaires and the effect of these questionnaires on risk factor relationships was compared. IIEF gave the highest age specific and overall ED prevalence, KEED the lowest. The difference in prevalence was 16.8%. The agreement (kappa coefficient) between the various ED definitions varied from 0.52 (IIEF & KEED) to 0.95 (Enigma & Boxmeer). The number of risk factor relations were similar for the Dutch studies, reduced for the IIEF and KEED. This study provides evidence that differences in questionnaires to assess ED have a considerable effect on the (age specific) prevalence estimates and little on the risk factor relations. The number of questions of the survey appears not to be responsible for differences in the prevalence of ED and risk factor relations, however they affect the response rate. Uniform use is strongly recommended, since a 'golden standard' for ED assessment (by questionnaire) is lacking. A short questionnaire with one or two questions is recommended for example the one from the Boxmeer-study. These data may be used to adjust (age-specific) prevalence rates comparing ED prevalence in the open population across studies.

Erectile dysfunction in primary care: prevalence and patient characteristics. The ENIGMA study.

The availability of adequate treatment for erectile dysfunction (ED) triggers studies into the prevalence of ED in the general population. Yet, previous studies showed different prevalence estimates partly due to differences in patient selection, in (unclear) definitions of ED and in assessment. ENIGMA has been designed to study the prevalence of ED in the general population of The Netherlands, using the WHO definition with a description of the way of assessment. In all, 5721 mail surveys were sent to all men, aged 18 y and older in 12 general practices in The Netherlands. A total of 5601 were included in the study and 2117 (38%) were completed. A total of 38% of the men reported to have ever had some kind of erectile problem. The prevalence of ED was 17% (6% mild, 4% moderate and 7% complete). Age, diabetes, cardiovascular diseases, penile disorders, irradiation in the pelvic region, relational problems, fear for failure, surmenage, medication use and regular consumption of alcohol were independently related to ED. Men with ED were less content with their (sexual) life and had less confidence in sexual performance. Presence of ED was negatively related to affected happiness in life. ED is commonly found in men and is related to age, medication, comorbidity and lifestyle factors. Men with ED perceive a lower quality of (sex)life. Doctors should be aware of the presence of ED and its consequences in patients.
