ABSTRACT

Introduction. Diabetic patients are at high risk of having erectile dysfunction (ED), but their doctors rarely pay attention to this association. Aim. To evaluate the treatment-seeking patterns and their correlates for ED in type 2 diabetic patients. Methods. A questionnaire containing Sexual Health Inventory for Men and questions inquiring treatment-seeking patterns was mailed or given to 4,040 subjects who had visited our endocrinology outpatient department for diabetes during January 2004 to May 2006. Main Outcome Measures. The prevalence of being bothered and having interest in treatment, and the percentage having sought treatment in regard to ED and their correlates with age and ED severity. Results. Of the subjects with questionnaire completed, 83.9% (708/844) had ED. Among the subjects with different severity of ED, the moderate group had the highest percentages regarding prevalence of being bothered (89.4%), having interest in treatment (78.5%), and having sought treatment (46.2%). Of all the subjects, only 14.2% had ever visited Western physicians, whereas embarrassment and misinformation about ED treatment were the leading reasons for never doing so. Over half (56.6%) of those with ED wished to discuss ED problem with their doctors, and of them 90.4% wished the doctors to initiate to broach this issue. Conclusions. The prevalence of ED and the concerns about it were high in these diabetic patients. ED severity was the major determinant of their treatment-seeking decision, whereas only few of them had ever sought professional help. Routine screening of ED in diabetic patients is recommended.

iabetes is a common comorbidity associated with the high risk of erectile dysfunction (ED). The probability of complete ED in diabetic patients is three times greater than those without [1]. ED has a negative impact on quality of life and interpersonal relationship that needs effective treatment [2]. The introduction of phosphodiesterase type 5 (PDE5) inhibitors provoked a fever of seeking treatment, but approximately

J Sex Med 2009;6:2008–2016

only 30% of ED patients have sought treatment [3,4]. Those who have chronic diseases, e.g., diabetes, are more likely to visit health-care providers and therefore have more access to seek professional help for ED problem [5]. The availability of effective oral medicine and advances in the understanding of ED problem has made this disease seemingly treatable by general health care providers. Jiann et al.

Investigating the prevalence of ED and realizing whether they are bothered by it or not are issues important to health-care providers. Unfortunately research on this issue is spare.

ferent age groups (26 to 45, 46 to 55, 56 to 65, 66 to 75, and 76 to 85 years) and with ED severity were also evaluated. The severity of ED was classified according to the sum score of SHIM as: 22–25 = no ED; 17–21 = mild ED; 12–16 = mild-moderate ED; 8–11 = moderate ED; and 1–7 = severe ED.

Aim

Exclusion Criteria To avoid being misclassified as having ED due to having no sexual activity in the past 6 months, the subjects who fulfilled several criteria were excluded. The exclusion criteria were: (i) the score of question Q1 in SHIM being greater than 2 (rating his confidence about erection better than “low” in the past 6 months); (ii) every score from Q2 to Q5 in SHIM being zero (no sexual activity in the past 6 months); and (iii) the answer to question “Do you consider yourself having erectile dysfunction” being “no.”

This study was conducted to evaluate the prevalence of ED in type 2 diabetic patients, their treatment-seeking patterns, and factors affecting them. Methods

Study Design and Participants Our study called for a sample of consecutive male subjects who had visited the outpatient department (OPD) of endocrinology under the diagnosis of diabetes mellitus (DM) at our institution during January 2004 to May 2006. A self-administered questionnaire composed of demographic data, questions regarding treatment-seeking patterns (Appendix) and a Chinese version of the Sexual Health Inventory for Men (SHIM) [7] was mailed to each of these subjects. To increase the response rate, subjects who did not respond initially were invited again to complete the questionnaire if they were seen by one of the endocrinologists in OPD at our institution during the period of June 2006 to May 2007. The demographic data in the questionnaire contained age, body weight, body height, marital status, smoking history, as well as a list of selfreported commorbidities including hypertension, dyslipidemia, coronary artery disease, uremia, depression, chronic liver disease, alcoholism, cancer, and cerebrovascular accident. This study was reviewed and approved by an independent Institutional Review Board at our institution. Main Outcome Measures Concerns regarding ED were evaluated by the prevalence of being bothered by ED and of having interests in ED treatment (positive response to Q2 and Q8 in Appendix) in the subjects with ED. If a man was “a little or modestly or highly” bothered by ED or having “some or much” interest in ED treatment, he was subsequently categorized in the group bothered by ED or having interests in ED treatment. The correlation of concerns about ED and percentage having sought treatment with dif-

Statistical Analysis The data would be analyzed by descriptive statistics. Chi-square test was used for comparison of categorical parameters, and Kruskal–Wallis test for comparison of numeric parameters without normal distribution. The level of significance was considered as P < 0.05. Results

A total of 4,311 consecutive subjects had visited the OPD of our endocrinology department during January 2004 to May 2006 for DM. After excluding 268 subjects with the wrong address and three being deceased, a questionnaire was mailed to the remaining 4,040 subjects. A total of 958 questionnaires were returned, of which 603 were obtained by return mail and 355 obtained from the OPD. The overall respondent rate was 23.7% (958/ 4,040). Compared with the nonresponders, the respondents were older (66.4 ⫾ 13.5 vs. 61.7 ⫾ 14.1 years, P < 0.05) in age and had more total visits in the endocrinology OPD during the past 2.4 years from January 2004 to May 2006 (10.8 ⫾ 7.2 vs. 8.2 ⫾ 6.9 visits, P < 0.05). The National Health Insurance Bureau in Taiwan recommended diabetic patients with stable condition to be followed up once per 3 months. For the respondents older than 55 years, the ED prevalence showed no significant difference among those whose questionnaires obtained by mail or from OPD. For the respondents younger than 56 years, the ED prevalence in those whose J Sex Med 2009;6:2008–2016

questionnaires obtained by mail was higher than those from the OPD (75.9% vs. 53.4%, P < 0.05). For the respondents having ED, the prevalence of being bothered by ED was higher in those whose questionnaires were obtained by mail than those from OPD (72.0% vs. 53.0%, P < 0.05). After excluding 32 subjects who fulfilled the aforementioned exclusion criteria, seven subjects older than 85 years, and three subjects with type 1 DM, a total of 916 subjects’ data was eligible for analysis in which 844 subjects had complete data of SHIM. According to SHIM score, 83.9% (708/ 844) of the subjects had ED with 15.4% being mild, 16.9% mild–moderate, 7.9% moderate, and 43.6% severe. Comparison of demographic data and common comorbidities between the subjects with and without ED were shown in Table 1. Those with ED were older in age and were more likely to have comorbidities, including hypertension, coronary artery disease, and depression. Their ED prevalence and severity were positively correlated with increasing age, P < 0.05 (Figure 1). Of the subjects with ED, 65.1% (456/700) reported to be more or less bothered by it with 37.4% being a little, 13.1% modestly; and 14.6% highly. Of the subjects with ED, 50.5% (351/694) had interests in ED treatment with 38.3% having some and 12.2% having much interest. Among the various severities of ED, the moderate group had the highest prevalence of being bothered and of having interests in ED treatment (Figure 2). J Sex Med 2009;6:2008–2016

With the same severity of ED, there was no significant difference in the prevalence of being bothered by ED among different age groups, except that in those with severe ED, the subjects older than 75 years had a lower prevalence than those younger than 76 years, P < 0.05 (Table 2).

in ED treatment, there was no significant difference among different age groups with mild ED. However, in groups of having more severe ED than mild, those younger than 66 years had a higher prevalence of having interest in ED treatment than those older than 65 years, P < 0.05. Only 27.8% (194/699) of the subjects with ED had ever sought treatment for ED through: counseling with a Western physician (14.2%); taking medication from over the counter (11.6%); adopting diet control or taking exercise (7.0%); or coun-

seling with a traditional Chinese medicine practitioner (5.3%). With the same severity of ED, there was no significant difference in the percentage having sought treatment (all P > 0.05) or having counseled with a Western physician for ED among different age groups (Table 3). But among the subjects with mild or mild–moderate ED, more of the subjects older than 65 years had sought counsel with Western physicians than those younger than 66 years (P < 0.05).

Discussion

Concerns about ED The prevalence of ED in our diabetic patients was as high as 83.9%. Having ED as well as having distress is prerequisite for males to seek treatment for ED [4]. Our results demonstrated that most of the diabetic patients with ED were bothered by their condition and are interested in the treatment for it. The reported percentages of ED patients who were bothered and wanted treatment varied from 50% to 80% [8–11]. Regional differences in culture, custom, and socioeconomic status may affect attitudes towards ED treatment. Different study subjects with various age and severity of ED account for the variation too. In our results, 65% of diabetic patients with ED felt bothered and 50% of them were interested in the treatment of it. For the subjects with moderate ED, both figures were over 80%. The age of subjects and severity of ED were reported to be associated with the rate of those seeking help [8,12,13]. Our results showed that ED severity, instead of age of the subjects, was the major determinant in the likelihood of being bothered and having interest in the treatment. Our data also demonstrated, however, that among the oldest age group (76–85 years), subjects with severe ED had fewer concerns about their ED. Similar results have been reported elsewhere [14–16]. A national survey of reproductive health and the concerns of Australian men demonstrated that the anxiety about ED among men with moderate–severe ED dropped markedly in the oldest age group (ⱖ70 years) than other younger groups [14]. A community-based study in The Netherlands showed that until 70 years of age, no age-dependent differences in the

Treatment Seeking for ED in Diabetic Patients concerns about ED were found, whereas men older than 70 years had much less concern [15]. A national survey among adults of 57 to 85 years of age in the United States demonstrated that the frequency of sexual activity did not decrease substantially with increasing age through 74 years of age. A greater proportion of the oldest age group (75–85 years) rated sex as being “not at all important” than the younger age cohorts [16].

Treatment-Seeking Rate The percentage having sought treatment in ED patients ranged from 10% to 60% [3,12,13,17,18]. As differences in regional backgrounds and study subjects may affect the prevalence of concerns about ED and attitudes toward treatment, they may also contribute to wide variation in the treatment-seeking rate. A survey of over 10,000 men using a free-call information service showed that those with a longer duration of ED (lasting >3 years vs. <6 months) were more likely to discuss the problem with a physician [12]. Eardley et al. demonstrated that men with severe ED were more likely to receive PDE5 inhibitors as part of their treatment [5]. A study of 637 impotent men between 50 and 76 years in New York revealed that there was no significant difference among the age groups in men seeking or not seeking treatment for ED [17]. Our results also showed that there was no significant difference in the percentage having sought treatment among different age groups with the same severity of ED, except that for those with mild or mild– moderate ED, the groups older than 65 years showed a higher inclination for counseling with a Western physician than those younger than 66 years. It indicates that when the ED is milder, men of older age are more likely to seek treatment than the younger ones. On the other hand, younger men are likely to believe in the spontaneous recovery from an erectile problem [19] and seek help relatively less. As the severity of ED influences both the degree in “bother” and interest in treatment, it also affects the percentage having sought treatment for ED. The percentage having sought treatment in each age group increased with the severity of ED, and peaked in those with moderate ED, then declined in those with severe ED. The finding that those with severe ED having sought treatment less frequently merits further interpretation. Those with severe ED were less likely to be bothered and interested in ED treatment, and herein less frequently sought treatment. Furthermore, those

2013 who were less bothered or less interested in treatment might have totally given up sexual activities and were reluctant to seek help. The phrase “use it or lose it” is particularly appropriate for the genitalia [20].

Obstacles of Treatment-Seeking in DM Patients Diabetes is a chronic disease requiring patients to visit health-care providers regularly, and diabetic patients theoretically have a greater access to professional help. The prevalence of ED in our diabetic patients was very high (83.9%) and most of them were bothered and interested in treatment. However, less than one-third of them had sought treatment for ED, and only 14% of them sought professional help (Western physicians). Embarrassment and misconceptions of knowing no effective treatment or considering treatment not good for health accounted for 74% of the reasons why these diabetic patients with ED had never counseled with a physician in spite of having interest in the treatment for it. Corona et al. demonstrated that among their ED patients, those with diabetes had a lower prevalence of hypoactive sexual desire than those without diabetes [21]. It suggested that they were more interested in restoring sexual activity than the other ED patients [21]. Most patients welcome their physicians to take the lead in discussing ED [10,18]. However, only 7.9% of our subjects had been asked about ED by their doctors. De Berardis et al. assessed 1,460 type 2 diabetic patients enrolled from 114 outpatient clinics in Italy and noted 63% of them reporting that their physicians had never investigated their sexual problems [22]. Another survey of 400 diabetes centers in Italy by Fedele et al. demonstrated that 51% of the centers did not investigate ED routinely, attributing this to structural problems, lack of specific training, and the availability of more specialized centers [23]. On the other hand, Baldwin et al. showed that patients appeared comfortable and willing to discuss their potency with their primary-care physicians than with urologists [24]. The documented physician inquiring about ED in a DM patient was 18% in a rural community in the United States, and the main reasons given by physicians for not initiating to discuss it were: “patients will mention;” discomfort; and lack of time [25]. Actually, of our subjects who wished to discuss it with their DM doctors, 90% wanted their DM doctors to initiate to broach the topic. J Sex Med 2009;6:2008–2016

2014

Screening ED in DM Patients Although some ED patients thought sex was not important, many reasons exist for physicians to screen sexual function. First, ED may be a precursor of other cardiovascular disease [26,27]. Second, poor glycemic control [28] and unhealthy life styles, such as smoking, are associated with ED. ED may be a real and threatening prospect for subjects to quit smoking or to have a better compliance with DM control measures [29]. Additionally, ED could cause interpersonal relationship problems and increase mental stress [2]. Furthermore, the study by De Berardis et al. also showed that ED was associated with higher levels of diabetes-specific health distress. Poor psychological adaptation to diabetes was, in turn, related to worse metabolic control [22]. Therefore, physicians taking care of DM patients should not overlook this association and act accordingly. Limitations The low respondent rate was a limitation of our study, and the prevalence of ED was likely to be overestimated, especially in the younger group as shown in the results. It was also very likely that the respondents were those more in favor of treatment than the nonrespondents. Therefore, our results of concerns about ED and the percentage having ever sought treatment for it were probably overestimated too. If this being true, it would underscore the low percentage of treatment seeking behavior in our subjects. Another drawback to our study was that our subjects were drawn from a teaching hospital, so that they might have more severe diabetes, better socioeconomic status, and as shown in the result, they might have better compliance and be older, than the general diabetic patients.

Conclusions

The prevalence of ED in diabetic patients was high and most of them felt bothered and had interest in treatment of it, but only few of them had actually ever sought professional help. ED severity was the major determinant of whether they felt bothered or sought treatment for it. Embarrassment related to discussing ED and misinformation about ED treatment were the main causes for not seeking professional help, and most patients wanted their doctors to initiate discussion of ED. Doctors taking care of diabetic patients were J Sex Med 2009;6:2008–2016
