Sexual functioning in obese adults enrolling in a weight loss study

Prevalence and predictors of female sexual dysfunction among sexually active women in the diabetes prevention program outcomes study

OBJECTIVE

To determine the burden and identify correlates of female sexual dysfunction (FSD) among women with prediabetes (PreD) and type 2 diabetes (T2D) enrolled in the Diabetes Prevention Program (DPP) Outcomes Study (DPPOS).

METHODS

The DPPOS visit included the Female Sexual Function Index (FSFI) to determine sexual function. Of 1464 participants, 1320 (90%) completed the (FSFI) and 426 were sexually active. A backward selection multivariable logistic regression model estimated the odds of FSD for sociodemographic, clinical, and diabetes-related covariates.

RESULTS

One hundred and eighty-five (43%) had a score of ≤26.55 and met the criteria for FSD. After adjustment for DPP treatment and age, urinary incontinence (UI) (odds ratio [OR] = 1.91, 95% confidence interval [CI] = 1.15-3.17) and hysterectomy (OR = 1.89, 95% CI = 1.01-3.53) were associated with increased odds of FSD. Increased body mass index was protective for FSD (OR = 0.93 per kg/m2, 95% CI = 0.89-0.96). Michigan Neuropathy Screening Instrument-based peripheral neuropathy (mean±SD scores 1.1±1.3 vs. 0.9±1.1, p < 0.0001) and Electrocardiogram (ECG)-based autonomic dysfunction measures (mean ± SD heart rate levels 64.3 ± 6.8 vs. 65.6 ± 10.2, p = 0.008) were associated with FSD. There were no differences in diabetes rates between women who did (66.5%) and did not (66%) have (p = 0.7).

CONCLUSIONS

FSD is prevalent in women with PreD and T2D. Our findings suggest that FSD is associated with neuropathic complications commonly observed in PreD and T2D.

Body perception and sexuality of bariatric surgery patients

PURPOSE

This study aims to determine how body perception and sexual life are affected in obese individuals who are hospitalized to undergo bariatric surgery.

DESIGN AND METHODS

Descriptive research design and the cross-sectional method were used. The study was conducted with 53 individuals who consented to participate. The data were analyzed with the SPSS software package.

FINDINGS

Low body perception and sexual dysfunction were detected, particularly in women.

PRACTICE IMPLICATIONS

In obesity treatment, the psychological and social problems that individuals experience due to obesity should be handled and evaluated with a multidisciplinary approach.

Sexual Functioning in Long-Term Survivors of Hematopoietic Cell Transplantation

This investigation characterized sexual activity and sexual function in hematopoietic cell transplantation (HCT) survivors, compared them with norms, and examined factors associated with sexual dysfunction, with the goal of identifying targets for intervention to improve sexual health. Surviving adults from a large transplantation center were asked to complete an annual survey with a core of health questions and a module on sexual activity and function. Participants completed the Sexual Function Questionnaire, Cancer and Treatment Distress form, and Revised Dyadic Adjustment Scale. Clinical data were collected from the transplantation medical database. Multivariate logistic regressions identified factors associated with sexual activity and function. Participating survivors (n = 1742) were a mean of 11.9 years (range, .4 to 43.1 years) after HCT, mean age 57.6 years, and 53% male. Women were more likely than men to report being sexually inactive in the past year (39% versus 27%) and, among those sexually active, to report low sexual function (64% versus 32%). Male and female survivors reported lower rates of sexual activity and function than comparison norms (all P < .01). In regressions, factors associated with being sexually inactive included older age, having <4 years of college education, low performance status, and not being in a committed relationship. Additional factors for men included receipt of nonmyeloablative conditioning and not being employed or in school. Low sexual functioning for men and women was associated with low performance status, and, for women, a committed relationship of lower quality, while for men the association was with older age. Sexual dysfunction is common in both men and women after HCT, regardless of time since treatment. Survivors need routine evaluation and access to multimodal interventions.

Deficits in Sexual Interest Among Adults With Schizophrenia: Another Look at an Old Problem

OBJECTIVE

Despite the important impact of sexuality on quality of life in adults, there is a paucity of research on this topic for people with schizophrenia. This study examined predictors of sexual interest among adults with schizophrenia.

METHODS

Using data from three studies with similar measures and participants with similar characteristics (N=231), the authors conducted a secondary analysis to examine the relationships among sexual interest, demographic characteristics (gender, age, living situation, and marital status), and clinical factors (sexual self-efficacy, symptom severity, and medications). Sexual interest was measured by using one item from the Scale to Assess Negative Symptoms. Binomial logistic regressions were conducted to explore factors most associated with level of sexual interest.

RESULTS

Separately, cardiovascular medications, gender, age, sexual self-efficacy, and negative symptoms were associated with sexual interest. In a logistic regression model that included all of these factors, only sexual self-efficacy and gender were significantly associated with sexual interest. Higher levels of sexual self-efficacy were associated with lower levels of impairment in sexual interest (odds ratio [OR]=0.98, 95% confidence interval [CI]=0.98-0.99, p<0.001), and males were less likely than females to have impaired sexual interest (OR=0.38, 95% CI=0.20-0.73, p=0.004).

CONCLUSIONS

The strength of the relationship between sexual self-efficacy and sexual interest warrants development of interventions to address sexuality among people with serious mental illness, at least for those who are interested in developing or maintaining intimate relationships. An intervention that teaches skills needed to successfully pursue and navigate intimate relationships could positively influence overall quality of life for many.

Effect of Body Weight on Sexual Function in Men and Women

PURPOSE OF REVIEW

Obesity is a growing problem worldwide. This review aims to summarize the literature on the effects of weight on sexual function in both men and women from the past 5 years.

RECENT FINDINGS

In recent population-based studies of men and women, no relationship between weight and sexual function was identified. However, in studies of special populations such as women with gestational diabetes, polycystic ovarian syndrome (PCOS), pelvic organ prolapse or urinary incontinence, weight affected some aspects of sexual function. In women, surgical, but not non-surgical, weight loss was associated with resolution of some aspects of sexual dysfunction. In contrast, in men, both surgical and non-surgical weight loss improved sexual function.

SUMMARY

Weight plays a role in sexual dysfunction in both men and women. Bariatric surgery is linked to improved sexual function in both genders. However, more work is needed to fully understand the relationship between weight and sexual function.

Nocturnal Hypoxemia is Associated With Low Testosterone Levels in Overweight Males and Older Men With Normal Weight

STUDY OBJECTIVES

The relationship among obstructive sleep apnea (OSA), body mass index (BMI), and testosterone levels has long been suggested. Obese men have shown a negative correlation between testosterone level and sleep apnea severity. Yet, little is known about the association between testosterone levels and sleep apnea in men who are not obese. This study evaluated the association between the total testosterone (TT) level and OSA in patients who are not obese.

METHODS

A retrospective review of 523 records of patients in whom OSA was diagnosed from 2013-2016 was performed. The study included men with a BMI < 30 kg/m² and with TT levels measured in a blood sample collected the morning after a sleep study.

RESULTS

In all, 153 nonobese men met inclusion criteria, of whom 47 (30.7%) had testosterone levels below the reference values; 44 of these individuals (93.6%) were overweight (P = .029). Reduced testosterone levels showed significant correlations with the oxygen desaturation index, the lowest oxygen saturation < 80% (O₂ nadir < 80%), and rapid eye movement (REM) sleep duration, after adjusting for BMI. Among patients with normal weight, only 3 who had O₂ nadir < 80% and were older than 50 years presented with a reduced TT level.

CONCLUSIONS

In a large population of nonobese men with OSA, we demonstrated that hypoxemia (O₂ nadir < 80%) and overweight are associated with reduced testosterone levels. This association was only observed among normal-weight individuals older than 50 years.

Influence of obesity and hormone disturbances on sexuality of women in the menopause

OBJECTIVE

To assess influence of obesity and hormone disturbances on sexuality in the menopause.

METHODS

The study included 73 menopausal women, who were divided into groups according to body mass index (BMI) ≥ 26.7 kg/m². Anthropometric characteristics and blood pressure were measured. Blood was taken at 08:00 for hormones. All the participants filled in McCoy Female Sexual Questionnaire for the assessment of sexual life.

STATISTICS

Student's t-test, correlation, analysis of variance (ANOVA).

RESULTS

Follicle-stimulating hormone (FSH), luteinizing hormone (LH) and sex hormone-binding globulin (SHBG) were very significantly lower in obese compared to controls. E₂ and systolic blood pressure were very significantly, while diastolic blood pressure significantly higher in obese compared to controls. Obese women had significantly decreased frequency of pain during sexual intercourse (3.48 ± 2.64 vs. 4.09 ± 2.81). Influence of age on frequency of sexual intercourse was very significant. Significant influence in interaction between BMI and age on frequency of sexual fantasies as well as significant influence of BMI on satisfaction with partner as lover is also found.

CONCLUSION

Obesity has influence on different aspects of sexuality in the postmenopausal women. Our results suggest the need of awareness toward obesity and its impact on sexuality in the menopause.

Erectile Dysfunction is Common among Men with Acromegaly and is Associated with Morbidities Related to the Disease

INTRODUCTION

The prevalence of erectile dysfunction (ED) and its correlates in men with acromegaly has never been investigated.

AIM

The aim of this study was to evaluate sexual function in men with acromegaly.

METHODS

Multicenter-based, retrospective analysis of a nonselected series of 57 acromegalic subjects (mean age: 52.7 ± 14.2 years) was performed. Acromegalic subjects reporting ED (n = 24) were compared with matched ED patients without acromegaly or pituitary disease (controls), selected from a cohort of more than 4,000 subjects enrolled in the Florence Sexual Medicine and Andrology Unit.

MAIN OUTCOME MEASURES

Patients were interviewed using Structured Interview on Erectile Dysfunction (SIEDY) structured interview, a 13-item tool for the assessment of ED-related morbidities. Several clinical and biochemical parameters were taken. Penile color Doppler ultrasound (PCDU) was performed in a subgroup of 37 acromegalic subjects.

RESULTS

ED was reported by 42.1% of acromegalic subjects. After adjusting for age and testosterone, acromegalic subjects with ED had a higher prevalence of hypertension and more often reported an impairment of sleep-related erections and a longer smoking habit. Accordingly, acromegaly-associated ED was characterized by a higher organic component and worse PCDU parameters. No relationship between ED and testosterone levels or other acromegaly-related parameters was found. However, acromegalic subjects with severe ED reported a longer disease duration. In a case-control analysis, comparing acromegalic subjects with ED-matched controls free from acromegaly (1:5 ratio), acromegalic men had a worse ED problem and a higher organic component of ED, as derived from SIEDY score. In line with these data, acromegalic patients with ED had a higher prevalence of major adverse cardiovascular events history at enrollment and lower PCDU parameters.

CONCLUSIONS

Subjects with complicated acromegaly are at an increased risk of developing ED, especially those with cardiovascular morbidities. Our data suggest including a sexual function evaluation in routine acromegaly follow-up.

Comparing the effects of meal replacements with reduced-fat diet on weight, sexual and endothelial function, testosterone and quality of life in obese Asian men

Sexual dysfunction is more prevalent in obese than in normal-weight men. Meal replacements (MRs) are useful weight-loss strategies. We randomized obese (body mass index 27.5 kg m(-2), waist circumference (WC) 90 cm) Asian men (mean age 40.5 years, range 30-61) to a conventional reduced-fat diet (CD) (n=24) or MR-based plan (n=24) to reduce daily intake by 400 kcal for 12 weeks. There were significantly greater reductions in weight (4.2 ± 0.8 kg), WC (4.6 ± 0.7 cm), calorie and fat intake in the MR group, compared with the CD group (2.5 ± 0.4 kg, 2.6 ± 0.5 cm). Erectile function (International Index of Erectile Function 5-item score) improved comparably in the MR (3.4 ± 0.7 points) and CD (2.5 ± 0.5 points) groups, as did the Sexual Desire Inventory score (5.5 ± 2.3 vs 7.7 ± 2.1 points), quality of life (36-item Short Form survey score), plasma testosterone and endothelial function (Reactive Hyperemia Index). Subjects were switched to or continued CD for another 28 weeks. Weight, WC and erectile function were maintained at 40 weeks. MR induces greater reductions in weight and abdominal obesity than conventional diet, and comparable improvements in sexual and endothelial function, testosterone and quality of life.

Sexual functioning and obesity: a review

We review the literature on the relationship between obesity and sexual functioning. Eleven population-based studies, 20 cross-sectional non-population-based studies, and 16 weight loss studies are reviewed. The consistency of findings suggests that the relationship between obesity and reduced sexual functioning is robust, despite diverse methods, instruments, and settings. In most population-based studies, erectile dysfunction (ED) is more common among obese men than among men of recommended weight. Studies of patients in clinical settings often include individuals with higher degrees of obesity, with most studies showing a relationship between obesity and lower levels of sexual functioning, especially ED. The few studies that include both genders generally report more problems among women. Most studies of patients with comorbidities associated with obesity also find an association between obesity and reduced sexual functioning. Most weight loss studies demonstrate improvement in sexual functioning concurrent with weight reduction despite varying study designs, weight loss methods, and follow-up periods. We recommend that future studies (i) investigate differences and similarities between men and women with respect to obesity and sexual functioning, (ii) use instruments that go beyond the assessment of sexual dysfunction to include additional concepts such as sexual satisfaction, interest, and arousal and, (iii) assess how and the degree to which obese individuals are affected by sexual difficulties. Given the high prevalence of obesity and the inverse association between body mass and sexual functioning, we also recommend that sexual functioning should be more fully addressed by clinicians, both in general practice and in weight loss programs.

Sleep apnea, reproductive hormones and quality of sexual life in severely obese men

The effect of sleep apnea on the reproductive function of obese men is not entirely elucidated. The objective of this study was to define the effect of sleep apnea on the reproductive hormones and sexual function in obese men. This study included 89 severely obese men with BMI ≥35 kg/m2 considering gastric bypass surgery. Anthropometrics (weight, and BMI), reproductive hormones, and sleep studies were measured. The sexual quality of life was assessed using the Impact of Weight on Quality of Life-Lite questionnaire (IWQOL-Lite). The mean age of our patients was 46.9 ± 11.0 years, the mean BMI was 47.8 ± 8.7 kg/m2 and the mean weight was 337.7 ± 62.4 lb. After correction for age and BMI, means of free testosterone per severity group of sleep apnea were as follows: no or mild sleep apnea 74.4 ± 3.8 pg/ml, moderate sleep apnea 68.6 ± 4.2 pg/ml, and severe sleep apnea 60.2 ± 2.92 pg/ml, P = 0.014. All other parameters of sleep apnea including hypopnea index, percent time below a SpO2 of 90%, and percent time below a SpO2 of 80% were also negatively correlated with testosterone levels after correction for age and BMI. BMI and presence of coronary artery disease decreased the sexual quality of life. Sleep apnea was associated with reduced sexual quality of life. In summary, sleep apnea negatively affects testosterone levels independent of BMI. Severely obese men had decreased sexual quality of life.
