Abstract

Purpose

Erectile dysfunction is defined as the inability to achieve and/or maintain an erection of sufficient rigidity and duration to permit satisfactory sexual performance. The purpose of this study is to assess the prevalence of erectile dysfunction and associated factors among adult diabetic men on follow-up at Goba and Robe hospitals, Bale Zone, South East Ethiopia,2022.

Methods

Hospital-based cross-sectional study design was used among 420 adult diabetic men from March 1 to April 30 using a systematic random sampling technique. An international index of erectile function questionnaire containing five questions was used to assess the outcome variable. The data were entered, edited, and coded using Epidata version 4.6 and analyzed using SPSS version 26. Bivariable and multivariable binary logistic regression analysis were performed to identify factors associated with erectile dysfunction. Adjusted odds ratios with their corresponding 95% confidence interval were computed to estimate the strength of association. Statistical significance was declared at p-value < 0.05.

Results

The prevalence of erectile dysfunction was found to be 354 (84.3%). Multivariable logistic regression revealed that erectile dysfunction is significantly associated with old age (AOR = 12.39, 95% CI:5.10–30.08), inadequate physical activity (AOR = 4.15, 95% CI:1.33–12.97), and being rich (AOR = 2.62, 95% CI = 1.21–5.66).

Conclusion

The prevalence of erectile dysfunction in this study population is nearly nine out of ten. Age, inadequate physical activity, and wealth index were independent predictors of erectile dysfunction. Assessment and management of erectile dysfunction in diabetic clinics should be routine medical care.

Introduction

Erectile dysfunction(ED) is defined as the inability to achieve and/or maintain an erection of sufficient rigidity and duration to permit satisfactory sexual performance [1]. The degree of dysfunction has been used to classify erectile performance, and estimates of prevalence (the number of men who have the problem) vary depending on the definition of erectile dysfunction utilized [2]. Diabetes mellitus causes a number of short-term and long-term complications [3,4,5,6,7,8]. From long-term complications, erectile dysfunction is one of them [9,10,11]. Endothelial dysfunction, accumulation of advanced glycation end products, oxidative stress, and autonomic neuropathy are all linked to the pathogenesis of erectile dysfunction in diabetic patients. For example, diabetes may alter cavernous nerve impulses and endothelial cells, resulting in a neurotransmitter deficit [12, 13].

Erectile dysfunction has a major impact on job productivity and quality of life. Better management and early detection could help alleviate this cost, particularly in nations where erectile dysfunction is linked to poor economic and health consequences [14]. The 2018 American Urological Association clinical guidelines for erectile dysfunction recommend a shared decision-making approach between the physician and patient for the various treatment options. Erectile dysfunction remains an underdiagnosed and undertreated condition associated with many healthcare conditions [15,16,17,18]. Providers are missing a significant chance to improve their patients’ quality of life by failing to recognize erectile dysfunction. Even though, erectile dysfunction has a detrimental impact on diabetes patients’ lives, frank discussion of sexually related issues is frowned upon in Ethiopia. As a result, sexual disorders in Ethiopia are under-recognized and under-treated [19].

Sexual function is a key indicator of life satisfaction. Men’s social interactions, emotional and psychological well-being, and partner relationships have all been shown to be negatively impacted by erectile dysfunction [20]. According to the literature, about 95% of cases of erectile dysfunction can be successfully treated [21]. Erectile dysfunction is associated with mortality, but the link between low testosterone and greater mortality is still debatable. Low testosterone and sexual dysfunction frequently coexist, although it is unknown how important low testosterone is in predicting death compared to sexual symptoms [22]. Over 50% of men between the ages of 40 and 70 experience erectile dysfunction, which is a common health issue in older men [23]. Even though more common as people get older, it is not a natural aspect of the aging process. Older men are more likely to develop testosterone deficiency, especially those who are obese, have type 2 diabetes, chronic kidney disease (CKD), and other comorbid conditions, such as acute COVID-19 infection and its long-term effects, as well as those who are taking medications, particularly opiates, anabolic steroids, antipsychotics, and anticonvulsants [24]. Erectile dysfunction isn’t just about being unable to have satisfying sexual intercourse, it is frequently associated with emotional and psychological stigma [1, 25].

A couple of years ago, erectile dysfunction was one of the most neglected complications of diabetes [25]. In the past, physicians and patients were led to believe that declining sexual function was an inevitable consequence of advancing age or was brought on by emotional problems. This myth, combined with men’s natural reluctance to discuss their sexual problems and physicians’ inexperience with sexual issues, failed to directly address this problem with the majority of patients experiencing it [26]. Erectile dysfunction tends to occur earlier in diabetic patients than in normal individuals [7, 27]. According to several kinds of research, erectile dysfunction has both psychological and social impacts on men, including a loss of confidence in their lifestyle, anxiety, depression, loss of personal relationships, significant repercussions on their self-esteem, and a loss of social and work activities [28, 29]. The problem is a huge burden behind divorce, especially for young couples [30].

A variety of studies have been conducted to determine the magnitude of erectile dysfunction and its determinants [26, 31,32,33,34,35,36]. However, the wide scope of the problem necessitates studying and analyzing the various factors that are potentially associated with erectile dysfunction at once [37, 38]. In addition to the variables covered in earlier studies, wealth-related variables are considered in this study. In the past, researchers have tried to investigate the problem [26, 28, 36, 38,39,40,41]. In particular, no research has been conducted in Southeastern Ethiopia. Therefore, this study aims to determine the magnitude of erectile dysfunction and associated factors among adult diabetic men on follow-up at Goba and Robe hospitals.

Materials and methods

Study area and period

The study was conducted at Goba and Robe hospitals in Oromia region, Bale zone which is located 435 km to the southeast of Addis Ababa, Ethiopia. Goba Referral Hospital is the only referral hospital in the Bale zone that serves as a teaching hospital for medical and health sciences. Data was collected from March 1 to April 30, 2022 by two trained male nurses.

Study design

Hospital-based cross-sectional study design.

Source population

All diabetic men who visit chronic outpatient departments of Goba and Robe Hospitals.

Study population

All adult diabetic men who fulfill eligibility criteria and have follow-up at Goba and Robe hospitals during the data collection period.

Eligibility criteria

Inclusion criteria

Adult diabetic men aged ≥ 18 years who also had a history of sexual intercourse.

Exclusion criteria

Critical patients with hyperosmotic hyperosmolar state or diabetic ketoacidosis, mentally incompetent, Psychotic patients, Patients with previous pelvic surgery, Patients who had pelvic trauma, Patients who had a spinal injury, Patients taking anti-psychotic medications, patients with any malignancies and patients with benign prostatic hyperplasia were excluded from the study through history taking and physical evaluation.

Sample size determination

The study sample size was determined using epi-info 7 based on assumptions of 95% confidence level, 5% margin of error, the proportion of erectile dysfunction 54.3% [19], and non-response rate of 10%. The maximum sample size was obtained for 54.3% proportion. Taking a non-response rate of 10%, the final sample size is 420.

Sampling technique

A systematic random sampling technique was used to select study subjects. The average number of monthly adult diabetic cases seen in the outpatient department of Goba and Robe hospitals within the preceding six months were taken (from Goba 600 and Robe 460) and divided by proportionally allocated sample size (238 for Goba and 182 for Robe hospitals). When we divide this by the allocated sample size for each hospital the quotient is the interval chosen to select each case. Therefore, the respondents were interviewed every 2 and 3 patients for Goba and Robe hospitals respectively. The medical record number was taken for each patient to avoid duplication.

Variables

Dependent variable

Erectile dysfunction is the outcome variable for this study. It was assessed using International Index of Erectile Function (IIEF) questionnaire. This questionnaire consists of five questions, each with Likert scale alternative responses. The greatest possible score is 25, which is the score for people who never had an erection problem and the lowest score is 5. The sum of the ordinal replies to the 5 items determines the IIEF-5 score. The erectile dysfunction was categorized into two depending on the IIEF score. Those who score 22 and above were classified as having no erectile dysfunction and those who score 21 and below were classified as having erectile dysfunction. More specifically, those who have a score of 17–21, 12–16, 8–11, and 5–7 are sub-categorized as having mild, mild to moderate, moderate and severe erectile dysfunction respectively [42].

Independent variables

Socio-demographic and economic characteristics

Age, Place of residence, Marital status, Ethnicity, Religion, Occupation, Educational status, Income.

Wealth index

Principal component analysis was done for common household assets. The requirements for the analysis like large sample size, the ratio of cases to variables, KMO > 0.6, and Bartlett test of sphericity statistical significance(P < 0.05) were checked and satisfied. Accordingly, KMO = 0.601 and Bartlett’s test of sphericity < 0.001. Four variables number of chicken, radio, refrigerator, and wrist watch with eigen value greater than one were extracted and explained 24.29%, 18.17%, 13.5%, and 12.77% respectively. The total wealth index variability explained by principal component analysis was 68.74%.

Treatment and lifestyle

Types of diabetes, Duration of diabetes, Types of treatment, BMI, Waist circumference, Hip circumference, Waist to hip ratio, Smoking, Alcohol, Khat chewing, Physical activity, Diet.

Comorbidities and Complications

Hypertension, Antihypertensive medications, Cardiac disease, Cardiac drugs, Eye disease, Renal disease, Stroke, Peripheral neuropathy.

Mental and psychological factors

Depression.

Operational definition

PHQ-2 and PHQ-9(patient health questionnaire)

were used to assess variable depression. The PHQ-2 inquiries about the frequency of depressed mood and anhedonia over the past two weeks. It includes the first two items of the PHQ-9. The purpose of the PHQ-2 is to screen for depression in a “first-step” approach. Patients who screen positive or have a score of ≥ 3 should be further evaluated with the PHQ-9 to determine whether they meet the criteria for a depressive disorder [43]. PHQ-2 score ranges from 0 to 6 [44]. PHQ-9 tool contains nine questions with four options of answers. Each score was summed up and labeled accordingly [45]. For this study, score of 10 and above were used to define depression with good sensitivity.

International Physical Activity Questionnaire (IPAQ)

This assesses the types of the intensity of physical activity and sitting time that people do as part of their daily lives are considered to estimate total physical activity in MET-min/week and time spent sitting [46]. The total number of days and time in minutes spent on activities within a week will be multiplied by their corresponding MET vigorous, moderate, and walking activities. The outcome was categorized and named as high (At least 3000 MET), moderate (At least 600 MET but less than 3000 MET) and low (unable to classify as high or moderate) for vigorous, moderate, and walking activities respectively.

Waist circumference

Is a measurement of abdominal obesity and provides independent risk information that is not accounted for by body mass index. It is measured with flexible tape placed on a horizontal plane between anterior superior iliac spine and the lower rib. A normal waist circumference for male should be less than 102 cm [47].

Waist-to-hip-ratio (WHR)

Measures the ratio of waist circumference to hip circumference. It determines how much fat is stored on waist, hips, and buttocks. Even though, the cut off value vary from population to population a WHR of 1 and above increases risk of metabolic syndrome [48].

Data collection tool and procedure

After reviewing different works of literature [41, 42, 49,50,51], a written structured questionnaires were prepared to determine the prevalence of erectile dysfunction and associated factors among adult diabetic men at Goba and Robe hospitals. The English version of the questionnaire was translated into Afan Oromo and Amharic, the local languages spoken in the study area. After the translation, the questionnaire was -translated back to English to check the consistency. Data were collected through interviewer administered questionnaire and physical measurements. The standard tools used for this study were WHO STEPS-wise questionnaires, summary of diabetes self-care activities, international physical activity questionnaire, public health questionnaires, international index of erectile function and Ethiopian demographic and housing survey data. The selection of these hospitals was made based on patient flows and the comprehensive service they provide. The data were collected by interviewing the patients individually by two trained male nurses on working days. The international index of erectile function questionnaires was used to screen the patients for erectile dysfunction. A separate and quiet room was used for data collection. The remaining data were retrieved from the patients’ documents using prepared checklists.

Data quality control

The principal investigator gave training for two male nurses before the data collection period. The data collectors were capable of speaking local languages. The training was given on the objective of the study, actual data collection procedure, the contents of the questionnaires, and matters related to confidentiality. Additionally, to maintain the quality of data pretest was conducted by the principal investigator at Ginnir hospital on 5% of the sample size to check the validity and know whether the questionnaires are understandable or not a week before beginning the actual data collection period. The modification was made to the questionnaire that is found with any ambiguity and affects its consistency. During data collection, the principal investigator gave onsite technical support and close supervision. Data were checked daily by the principal investigator for completeness, and consistency and then errors were corrected accordingly before data processing and analysis.

Data processing and analysis

Data were edited, coded and entered by Epidata version 4.6 and were exported to SPSS (version 26) for analysis. The data analysis started from a basic description to the identification of potential factors associated with erectile dysfunction. Bivariable and multivariable logistic regression were used to identify the relationship between erectile dysfunction and various factors. The assumptions of the logistic regression model Hosmer-Lemeshow goodness of fit statistics was checked and satisfied. Multivariable logistic regression was used to identify potential confounding variables. Multicollinearity among independent variables were checked using tolerance and variance inflation factor. Normality for independent variables was checked using Shapiro wilk. Principal component analysis was performed for common household assets. Descriptive summaries were computed as simple frequencies, mean, median and standard deviations. All explanatory variables which resulted in p < 0.25 with the outcome variable in the bivariable were entered into a multivariable logistic regression model to identify factors associated with erectile dysfunction. P-Value < 0.05 was considered statistically significant and the adjusted odds ratio with a 95% confidence interval was used to declare association.

Behavioral and lifestyle characteristics of adult diabetic men attending diabetic clinic at Robe and Goba Hospitals(n = 420), 2022

Among 420 respondents only 6 (1.4%) smoke tobacco products currently and 5 (1.2%) of them smoke tobacco products daily. The average age at first started smoking daily is 31.67 (SD ± 8.14) and it happened 35.23 (SD ± 6.28) years ago. Sixty-four (15.2%) out of 420 respondents were past smokers and the median age at stopping cigarettes was 30 years. Regarding alcohol consumption 143 (34%) ever consumed alcoholic drinks. The median number of occasions of having at least one alcoholic drink during the past 30 days is two. On the other hand, the median standard alcohol drinks during the past 30 days are two. The median number of having the largest standard alcoholic drinks counting all types of drinks during the past 30 days is four. Likewise, the median number of having five or more standard alcohol drinks on a single occasion in the past 30 days is zero.

Regarding fruit and vegetables, the median number of days of fruit and vegetable consumption is 1 and 2 respectively. The median number of servings of fruits and vegetables in a typical week is 1. The median number of meals eaten that were not prepared at home per week is zero. More than half of the participants 240(57.1%) don’t skip their breakfast in a typical week and the most commonly used oil for meal preparation was vegetable oil 373 (88.8%).

Prevalence of erectile dysfunction

The mean score of erectile dysfunctions based on IIEF was 16.17(SD ± 4.65) ranging from 5 to 25. The prevalence of erectile dysfunction was found to be 354 (84.3%) of this 126 (30%) had mild erectile dysfunction,146 (34.8%) had mild to moderate erectile dysfunction, 67 (16%) had moderate erectile dysfunction and 15 (3.6%) had severe erectile dysfunction. The remaining 66 (15.7%) had normal erectile function (Fig. 1).

Factors associated with erectile dysfunction

Variables like age, physical activities, types of diabetes, presence of hypertension, waist to hip ratio, waist circumference, and wealth index had a p-value of less than 0.25 in bivariable logistic regression and hence exported to multivariable logistic regression analysis for controlling possible confounders. Multivariable binary logistic regression analysis showed age, physical activities, and wealth index to be statistically associated with erectile dysfunction. More specifically, the odds of having erectile dysfunction among those who are ≥ 45 years old are about 12.39 times higher compared to young age groups (AOR = 12.39 ,95% CI = 5.10-30.08, p-value = < 0.001). Likewise, rich diabetic men are 2.62 times at higher risk of having erectile dysfunction compared to poor (AOR = 2.62, 95% CI = 1.21–5.66, p-value = 0.014) (Table 3).

Discussion

This study assessed the prevalence and factors associated with erectile dysfunction among adult diabetic men on follow-up at Robe and Goba hospitals. In this particular study, the prevalence of erectile dysfunction among adult diabetic men was 354 (84.3%). This finding is in line with research conducted in the Amhara region of Ethiopia 85.5% [41], in Ghana 81.8% [52] and Indonesia 84.4% [53]. Moreover, this study found a higher prevalence compared to researches done in most areas of Ethiopia(54.3-69.9%) [19, 39, 54, 55], Eritrea 74.2% [56] ,Tanzania 55.1% [50], recent systematic review done in Africa 71.45% [57], Western Asia 62.2% [58], China 64.2% [40], South America 74.6% [59], Bangladesh(45.3-60.2%) [35, 60], Sri Lanka 62.9% [51], Pakistan 21.1% [31], Nepal 76.8% [61], India 68.5% [27] and Europe 67.4% [62]. This might be due to the study participants characteristics like older age and higher fasting blood sugar. Therefore, poor adherence to diabetic medications and older age may be responsible for the observed higher prevalence. Consequently, it becomes essential to undertake appropriate and proactive management of diabetes mellitus such as, healthy lifestyle choices, and regular glycemic monitoring, to minimize the occurrence of adverse health events associated with diabetes, including erectile dysfunction. In addition, the finding raises the issue of diabetic medication potency and storage areas. This can be due to the high fasting blood sugar level in more than half of the study participants. Similarly, insulin is a protein hormone that can be sensitive to temperature changes. Extreme heat or freezing temperatures can degrade the insulin molecules and render them ineffective. Even though most of the patients are from urban areas, they don’t have proper storage areas like refrigerators. On the contrary, the prevalence of erectile dysfunction is a bit lower compared to the studies conducted in Morocco (88%) and Nigeria (94.7%) [63, 64]. The possible reason may be attributed to the socio-cultural context of the study participants, study design, and sample size.

The factors associated with erectile dysfunction in this study are age ≥ 45, inadequate physical activities (< 600 MET), and being rich. This study showed that being older (≥ 45 years) is 12.39 times more likely to develop erectile dysfunction which is in line with most studies [51, 53, 54, 56, 65]. This can be due to age-related physiological changes like decreased testosterone production in older men [66].

In this study, less or inadequate involvement in physical activities showed a strong association with erectile dysfunction. Adult diabetic men with inadequate physical activities are more than threefold likely to develop erectile dysfunction. This finding is supported by studies conducted in Ethiopia and a recent systematic review done in Africa [36, 57, 65]. The possible explanation for this could be exercise reactivate penile tissues and improve erection. And hence, men with low physical activity are at higher risk of developing erectile dysfunction [67].

Another important factor associated with erectile dysfunction in this study is wealth index. Rich diabetic men are 2.62 times at higher risk of developing erectile dysfunction compared to poor ones. This finding is consistent with the research conducted in Ghana [68]. This is due to the fact that being rich puts individuals at higher risk of developing obesity. Being rich can often be seen as an indirect measure of certain characteristics, such as having better access to high-quality healthcare, a wider range of nutritious food options, and the ability to consume energy-dense foods. Additionally, individuals with higher wealth tend to have a lower likelihood of being involved in physically demanding occupations, thus increasing the likelihood of leading a sedentary lifestyle [69,70,71].

Unlike other studies, this particular study has not shown the association of longer duration of diabetes, type of diabetes, alcohol intake, and cigarette smoking habit with erectile dysfunction. This may be due to socio-cultural conditions of the community.

Strength and limitations

This study used standard tools like WHO STEPS-wise questionnaires, summary of diabetes self-care activities, international physical activity questionnaire, public health questionnaires and international index of erectile function. Over reporting of the cases might be there hoping for better management. This study didn’t measure micro and macrovascular complications in diabetic patients objectively. Similarly, HbA1C and serum testosterone level were not measured which could have shown long term glycemic control and hormonal level quantitatively. This is because we conducted the research in a poor set-up where there is no access to determine HbA1C and serum testosterone levels for each study participant.

Conclusion

In conclusion, the prevalence of erectile dysfunction among adult diabetic men is nearly nine out of ten. The risk of erectile dysfunction increased with age, wealth index, and inadequate physical activities. Giventhe higher magnitude of the problem, routine assessment and treatment of erectile dysfunction should be done at the diabetic follow-up clinic regularly. The treating healthcare providers should openly ask and assess the sexual history of adult diabetic men and intervene accordingly. Health education on the importance of adequate physical exercise and adherence to medication should be addressed strictly. Comorbidities should be sought and intervened timely and properly. The Ethiopian ministry of health should give due attention to chronic disease like diabetes mellitus. Separate and updated guideline for diabetic management and its complications should be prepared and distributed to each hospital. Researchers should do more investigations on large sample sizes incorporating laboratory parameters like HgA1c, ankle brachial index and serum testosterone so that updates on risk factors of erectile dysfunction and its management would be incorporated into management guidelines.
