Prevalence,incidence and risk factors of testosterone deficiency in a population-based cohort of men: results from the study of health in Pomerania

Objective.?Low total testosterone levels (TT) have been associated with increased morbidity and mortality. However, the prevalence and incidence of testosterone deficiency (TD) in association with its risk has not been assessed systematically to date.

Methods.?Data from the prospective population-based Study of Health in Pomerania were used. From the 2117 men aged 20–79 years at baseline, 1490 men with complete TT data were analysed. Crude and age-specific prevalence and incidence rates of TD were estimated by TT levels below the age-specific 10th percentile. Analysis of covariance and Poisson regression models were used to assess the association of socio-demographic characteristics, health-related lifestyle, as well as somatometric, medical and laboratory measures with risk of incident TD.

Results.?TD baseline prevalence was 10.4% (N?=?155) and incidence 11.7 per 1000 person-years. TT levels showed a significant age-related decline with an unadjusted rate of 0.05 nmol/l per year. Obesity, metabolic syndrome, diabetes and dyslipidaemia were identified as risk factors of incident TD. Subpopulations of men without the revealed risk factors at both examinations maintained constant TT levels over time.

Conclusions.?Besides aging alone, lifestyle and different comorbidities were associated with TT level decline, suggesting that the age-related TT decline may be at least partly prevented through the management of potentially modifiable risk factors and health related behaviour.     

Discrimination,mental health,and body image among transgender and gender-non-binary individuals: Constructing a multiple mediational path model

The purpose of the current study was to examine the relationships among discrimination, mental health, and body image in a national sample of transgender adults. Participants (N = 78) identified as transgender, genderqueer, or other gender-non-binary identities and were recruited via a national online survey. Harassment/rejection, work/school, and other discrimination explained 10.4% of the variance in body appreciation, while satisfaction with life, anxiety, self-esteem, and depression explained 60.7%. Within these models, harassment/rejection was inversely associated with body appreciation, while self-esteem and satisfaction with life were positively associated. A series of path models moving from a measurement model to a more parsimonious and excellent-fitting model found that the effect of harassment/rejection on body appreciation was fully mediated by self-esteem and satisfaction with life, resulting in a multiple mediation.     

Aging male's symptoms in a Southern Brazil population: lifestyle effects after the age of 40

Background.?The interest of epidemiological research about male's aging increased in recent years along with the need to evaluate health-related quality of life. We conducted a population-based cross-sectional study to identify the prevalence of aging male's symptoms (AMS) and factors associated to this condition.

Methods.?The study included 421 men aged 40 years or older, living in the urban area of Pelotas, Southern Brazil. The questionnaire covered sociodemographic, behavioral, and health variables, and to verify the aging male's symptoms, the AMS Scale was used.

Results.?Moderate/severe male's symptoms was considered positive (AMS scores equal or above 37 points) in 20% of men (95% CI 16.1; 24.3). After controlling for confounders, the AMS was significantly associated with aging, self-perceived health status and smoking. The symptoms were more severe among physically inactive men.

Conclusions.?Our findings support the necessity to maintain healthy behaviors like not smoking and regular physical activity since such changeable behaviors could reduce the AMS acceleration and increase life quality and expectancy.     

Family Functioning and Mental Health of Transgender and Gender-Nonconforming Youth in the Trans Teen and Family Narratives Project

Transgender and gender-nonconforming (TGN) youth are at increased risk for adverse mental health outcomes, but better family functioning may be protective. This study describes TGN youth’s mental health and associations with family functioning in a community-based sample. Participants were from 33 families (96 family members) and included 33 TGN youth, ages 13 to 17 years; 48 cisgender (non-transgender) caregivers; and 15 cisgender siblings. Participants completed a survey with measures of family functioning (family communication, family satisfaction) and mental health of TGN youth (suicidality, self-harm, depression, anxiety, self-esteem, resilience). TGN youth reported a high risk of mental health concerns: suicidality (15% to 30%), self-harm (49%), clinically significant depressive symptoms (61%); and moderate self-esteem (M = 27.55, SD = 7.15) and resiliency (M = 3.67, SD = 0.53). In adjusted models, better family functioning from the TGN youth’s perspective was associated with better mental health outcomes among TGN youth (β ranged from ?0.40 to ?0.65 for self-harm, depressive symptoms, and anxious symptoms, and 0.58 to 0.70 for self-esteem and resiliency). Findings from this study highlight the importance of considering TGN youth’s perspectives on the family to inform interventions to improve family functioning in families with TGN youth.     

Harmonized Italian version of the aging males' symptoms scale

Introduction.?The interest in clinical investigations in health-related quality of life (HRQoL) of aging men has increased over recent years, particularly in the context of partial androgen deficiency. The aim of this paper is to inform the scientific community about a harmonized Italian Aging Males' Symptoms (AMS) scale.

Methods.?There were two slightly different Italian AMS scales, which both underwent an up-to-date linguistic & cultural translation process, i.e., were both valid to be applied in clinical research. However, there are potential long-term problems associated with having two Italian language versions of the scale in the same country. Therefore, an ad hoc committee of key persons related to both versions met with the scale's developer, to create a harmonized single Italian AMS.

Results.?The harmonization meeting came up with a consensus item-by-item and the new Italian reference scale was agreed upon. It was decided that this scale should be published to avoid any confusion among future users.

Conclusion.?The Italian AMS scale published in this paper should be used for future clinical and other research.     

Experiences with the French aging males' symptoms (AMS) scale

Introduction.?The aim of this paper is to report on experiences gained from the application of the French version of the Aging Males' Symptoms (AMS) scale, to show correlations with other relevant scales and to provide population reference values for France.

Methods.?A representative survey based on an existing, representative population panel was performed in France (963 males, aged 15 + years). Other AMS data from Europe were then used for comparison. Mean scores of the French AMS scale do not systematically differ from the data of other European studies. The population reference values obtained for France strongly suggest that the scale measures can appreciate the level of well-being whatever the patients' age; however, some variables, such as age and family income, can influence the total AMS scores. Comparisons with the generic quality-of-life scale, SF-12, and a depression scale, HAD, have shown good correlations, as have comparisons with the ADAM questionnaire.

Conclusion.?The French AMS scale is a standardized, valid and simple health-related quality of life (HRQoL) scale, with results comparable to other published European findings. The results also indicate that the AMS scale can be used to measure and compare HRQoL in those less than 40 years of age.     

ABSTRACTS OF The 2nd Asian ISSAM Meeting on the Aging Male Taipei,Taiwan March 6–9, 2003

Background.?It is of interest to understand whether impaired physical function is associated with health-related quality-of-life (HRQOL). We examined upper and lower body physical function and its relationship with two domains of HRQOL among men.

Methods.?We conducted a population-based observational study of musculoskeletal health among Boston, MA residents, the Boston Area Community Health/Bone Survey. Participants were 1219 randomly-selected Black, Hispanic, and White males (30–79 years). Upper body function was measured using hand grip strength, while lower body function was measured by combining a timed walk and a chair stand test. HRQOL was measured using the physical (PCS-12) and mental health (MCS-12) component scores of the SF-12. Multivariate linear regression models were used to estimate the association between poor function and HRQOL.

Results.?There was a significant association of poor upper body physical function with the MCS-12 (β coefficient:??4.12, p?=?0.003) but not the PCS-12 (β coefficient: 0.79, p?=?0.30) compared to those without poor function. Those with poor lower body physical function had significantly lower PCS-12 scores (β:??2.95, p?=?0.007), compared to those without poor function, but an association was not observed for MCS-12 scores.

Conclusions.?Domains of physical function were not consistently related to domains of HRQOL.     

The impact of irritative lower urinary tract symptoms on erectile dysfunction in aging Taiwanese males

Objective.?This study assessed the possible associations between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED) in aging Taiwanese males and investigated the impact of various aspects of LUTS on ED.

Methods.?A free health screening for aging males (≥40 years old) was conducted in Kaohsiung Medical University Hospital. All the subjects had completed clinical data and answered questionnaires. ED and LUTS were assessed by validated symptom scales: the International Index of Erectile Function-5 (IIEF-5) and the International Prostate Symptom Score (IPSS).

Results.?A total of 339 eligible patients enrolled in this study with a mean age of 60.1 years old. In multiple logistic regression analysis, age and IPSS (p?<?0.001 and p?=?0.013, respectively) were significantly associated with ED after controlling other comorbidities. In a further age-adjusted multiple regression analysis, our results showed that irritative symptoms (p?=?0.042) have a more significant association with ED than the obstructive symptoms (p?=?0.101).

Conclusions.?Our results indicate that age and LUTS are the two most independent risk factors for ED. Aging Taiwanese males with LUTS are at increasing risk for ED, especially for those with significant irritative symptoms.     

Transitions,Subjective Age,Wellness, and Life Satisfaction

ABSTRACT

A study of 221 midlife women, 35 to 65 years of age, was conducted to explore the relationships among transitions, subjective age, wellness, and life satisfaction for lesbian (n= 81), bisexual (n =14), and heterosexual women (n= 126). Although the sample of bisexual women was too small to permit valid statistical analyses for this group, it is noteworthy that experiencing physical signs of aging was the most frequently experienced transition by all groups. Entry into a committed relationship was the second most frequently experienced transition by the lesbian participants, and entry into perimenopause was the second most common for heterosexuals. Lesbians whose subjective age was less than or equal to their chronological age reported greater wellness, and total wellness was a significant predictor of their life satisfaction. These findings suggest that all women experience midlife as a time of change and development, and lesbian women face specific challenges that require coping to maintain a sense of well-being during the midlife years.     

Oral administration: a preferred route of testosterone intake

Objective.?The influence of prostate-specific antigen (PSA) kinetics on the outcome of metastatic prostate cancer (PCa) after androgen-deprivation therapy (ADT) remains poorly characterised. We evaluated the prognostic significance of PSA nadir and time to PSA nadir as well as their interactive effect on prostate cancer-specific mortality (PCSM) and all-cause mortality (ACM) after ADT.

Methods.?A total of 650 men with advanced or metastatic PCa treated with ADT were studied. The prognostic significance of PSA nadir and time to PSA nadir on PCSM and ACM were analysed using Kaplan–Meier analysis and the Cox regression model.

Results.?On multivariate analysis, clinical M1 stage, Gleason Score 8–10, PSA nadir ≥ 0.2 ng/ml and time to PSA nadir < 10 months were independent predictors of PCSM and ACM. The combined analysis showed that patient with higher PSA nadir and shorter time to PSA nadir had significantly higher risk of PCSM and ACM compared to those with lower PSA nadir and longer time to PSA nadir (hazard ratios?=?6.30 and 4.79, respectively, all P < 0.001).

Conclusions.?Our results suggest that higher PSA nadir level and faster time to reach PSA nadir after ADT were associated with shorter survival for PCa.     

Soy protein based supplementation supports metabolic effects of resistance training in previously untrained middle aged males

Abstract

Objective.?To determine changes in body composition, physical performance, metabolic and hormonal parameters induced by lifestyle counselling, resistance training and resistance training with soy protein based supplemention in middle aged males.

Design.?Randomised controlled study consisting of resistance training without (RT-G) or with (RTS-G) a soy protein based supplement and a control group with lifestyle education only (LE-G).

Subjects.?Forty healthy middle aged men (50–65 years, BMI 25–29.9 kg/m²).

Measurements.?Changes in body weight (BW) and waist circumference (WC) were measured and body composition (BC), fat mass (FM), lean body mass (LBM) were measured by skin fold anthropometry at baseline and after 12 weeks of intervention. In addition, changes in physical fitness, metabolic and hormonal parameters (lipids, glucose, fructosamines, insulin, insulin-like growth factor-1, Leptin, human growth hormone, dehydroepiandrosterone, testosterone, hs-CRP, Il-6) were evaluated.

Results.?Thirty-five participants completed the 12 week study. No significant changes in BW were noted although RM and WC dropped and LBM increased after training, particularly in the RTS group (FM 22.6?±?5.5?kg to 21.2?±?4.7?kg; LBM 68.5?±?7.2?kg to 70.1?±?7.4; p?<?0.01). Subjects in the RTS group experienced more pronounced improvements in the strength measurements than the RT group. After the training intervention there were significant changes in hormonal and metabolic parameters as well as in glycemic control, particularly in the RTS group.

Conclusions.?Our data suggest that resistance training, particularly in combination with a soy protein based supplement improves body composition and metabolic function in middle aged untrained and moderately overweight males.     

The effect of 6 months of androgen deprivation therapy on muscle and fat mass in older men with localized prostate cancer

Objective.?To evaluate body composition changes, specifically skeletal muscle mass, in men receiving androgen deprivation with luteinizing-hormone releasing hormone-agonist (LHRH-A) for prostate cancer (PCa) in comparison with healthy controls.

Design.?Retrospective analysis of body composition changes in men with prostate cancer receiving LHRH-A therapy from 2 clinical trials compared to men without prostate cancer serving as a placebo-control in another clinical trial.

Setting.?Clinical Research Center in Connecticut.

Participants.?Thirty men (> 60 years) receiving 6 months of LHRH-A therapy for PCa were compared to a healthy group of 25 men without PCa.

Measurements.?Appendicular skeletal muscle/height² (ASM/ht²), lean and fat mass were assessed by dual energy x-ray absorptiometry. Total testosterone levels were assessed by enzyme immunoassay.

Results.?At baseline, 12/30 (40%) of the treatment group and 7/25 (28%) of the control group (p = 0.11) met criteria for sarcopenia. There were no differences between control groups in ASM/ht² or lean mass. The LHRH-A group had a higher percent body fat than the control group, 29.8 ± 6.3 versus 26.3 ± 4.6 (p = 0.02). ASM/ht² and lean mass decreased in the LHRH-A group from 7.5 ± 0.9 kg to 7.3 ± 0.9 kg (?2.3% ± 0.03; p ? 0.001) and 53.5 ± 5.4 kg to 52.3 ± 5.3 kg (?2.1% ± 0.03; p ? 0.001), respectively. There was no muscle loss in the control group. At 6 months, the LHRH-A group had increased percent body fat from 29.8 ± 6.4 to 32.2 ± 5.8 (9.5% ± 0.13; p ? 0.001), whereas the control group had decreased in percent body fat from 26.6 ± 4.6 to 25.3 ± 5.0 (?3.8% ± 0.08; p = 0.02).

Conclusions.?Men undergoing LHRH-A treatment for PCa decreased appendicular skeletal muscle and lean tissue and increased body fat within 6 months of initiation of therapy. Lifestyle changes or medical interventions to minimize the effects of androgen deprivation therapy for PCa deserve investigation.     

Composite screener for androgen deficiency related to the aging males’ symptoms scale

Objective.?Methodological characteristics of the Aging Males’ Symptoms (AMS) scale point towards a high standard measurement and comparison of health-related quality of life (HRQoL) over time or intervention. However, the scale was neither developed nor standardized as a screening instrument for androgen deficiency.

Methods.?Data of the Austrian ANDROX study suggested to develop a composite screener for androgen deficiency based on AMS, age, and BMI, to determine sensitivity and specificity to detect low total testosterone (TT) levels. The findings were compared with those of an independent sample of urological patients with suspicion of androgen deficiency (AD) from Germany (n = 803).

Results.?A graphical solution for a composite-screening tool was proposed, with three levels of suspicion for AD: positive screening result (high suspicion), equivocal result, and negative screening result (no suspicion, AD unlikely). The percentage of TT values < 4 ng/ml were 18.7%, 40.7% and 58.8% in the three categories: negative, equivocal and positive, respectively. The findings were confirmed in the independent German sample. In both instances, neither sensitivity nor specificity was very high, i.e., between about 50% and 75%.

Conclusion.?The results of the development and initial validation of the new screener are promising. Further information, and experience from the practice, is needed to confirm or refute the hypothesis that this screener is a useful tool for medical practice.     

Impact of metabolic syndrome on erectile dysfunction and lower urinary tract symptoms in benign prostatic hyperplasia patients

Introduction.?The aim of this study was to investigate the relationship among metabolic syndrome (MetS), erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH).

Methods.?Our study included 106 patients with BPH, 33 (31.1%) of whom had MetS. Blood pressures, waist circumferences, serum levels of fasting blood glucose, high density lipoprotein and triglyceride of patients were recorded. Erectile functions of the patients were evaluated by International Index of Erectile Function (IIEF). Patients were divided into two groups according to IIEF scores, namely ‘mild/no ED’ and ‘moderate/severe ED’. IIEF scores of ED groups were between 17 and 30 and 6–16 in turn. LUTS severities were assessed by International Prostate Symptom Score (IPSS) and classified as mild (IPSS 0–7), moderate (IPSS 8–19) and severe (IPSS 20–35).

Results.?There was a significant difference between ED groups concerning MetS presence (p?=?0.032). MetS presence was not found to be associated with the severity of LUTS (p?=?0.144). There was no correlation between ED groups regarding LUTS severity (p?=?0.303).

Conclusion.?Results of the present study showed a correlation between MetS presence and ED. In the light of our results, MetS seems to play an important role in the etiopathogenesis of ED in patients with BPH.     

Relationship between testosterone serum levels and lifestyle in aging men

Objective.?The aim of this study was to evaluate the association between serum levels of testosterone and free testosterone to lifestyle in aging males.

Methods.?Men between 45 and 85 years were assessed regarding body mass index (BMI), nicotine and alcohol consumption, stress level, physical and social activity, and sleeping quality by a self-administered questionnaire. In parallel, serum levels of testosterone (T), free testosterone (fT), LH, FSH, DHEA-S, E2 and SHBG were obtained.

Results.?In total, 375 men with a mean age of 59.9 years (9.2 ± SD) entered this study; 25.4% and 27.4% had hypogonadal testosterone or free testosterone serum levels, respectively. Nicotine consumption (smokers had higher levels of T and fT; p < 0.01), BMI (negative correlation to T; p < 0.01) and age (negative correlation to fT; p < 0.001) correlated with serum levels of testosterone or free testosterone. Physical and social activity, nicotine and alcohol consumption, stress level and sleep quality did not show a significant association with serum androgen levels.

Conclusion.?This prospective study of 375 men aged 45 to 85 years confirms the correlation between age, BMI and smoking with serum levels of testosterone and free testosterone, whereas the investigated variety of lifestyle factors did not show a significant association to serum androgen levels.     

Original immunophenotype of blood endothelial progenitor cells and microparticles in patients with isolated arterial erectile dysfunction and late onset hypogonadism: effects of androgen replacement therapy

Objective.?Blood endothelial progenitor cells (EPCs) and endothelial microparticles (EMPs) have been proposed as markers of endothelial dysfunction. Aim of this study was to evaluate an original immunophenotype of EPCs and EMPs in patients with isolated arterial erectile dysfunction (ED) and late onset hypogonadism (LOH) before and after androgen replacement therapy.

Materials and methods.?Fifty patients (50–64 years) with ED and LOH were selected. EPC (CD45_neg/CD34_pos/CD144_pos) and EMP (CD45_neg/CD34_neg/CD144_pos) blood concentrations were evaluated by flow cytometry. Thirty patients received androgen replacement therapy (Tostrex® ProStrakan) for 6 months (group A), other 20 patients not received androgen therapy for the contraindications in their clinical history (group B).

Results.?After 6 months, group B showed IIEF-5 score, peak systolic velocity and acceleration time significantly worse than group A; in addition EPCs and EMPs were significantly higher in group B compared to group A.

Conclusions.?Patients with isolated arterial ED and LOH not treated with androgen therapy showed worst vascular parameters measured by penile Doppler and higher EPCs and EMPs compared to treated hypogonadal patients, hence, LOH appears to be an additional vascular risk factor, and these markers may be considered as predictors of cavernous artery disease. Finally, androgen therapy improves endothelial dysfunction.     

Sex-specific associations between sleep and mental health in university students: a large cross-sectional study

Abstract

Objective: To examine the associations between sleep problems and mental health dimensions in university students, and the effect of sex on these associations. Participants: Self-reported survey data from 3,483 students aged 18–30?years was drawn from a larger web-based study (i-Share) conducted in France in the years 2013–2017. Methods: We performed logistic regression analyses stratified by sex using insufficient sleep duration, poor sleep quality, difficulty initiating sleep and excessive daytime sleepiness, in relation with stress, self-esteem, depression and anxiety. Results: All sleep problems were strongly associated with all mental health dimensions, particularly anxiety, in female students. Sleep and mental health problems were also associated in male students, with the exception of low self-esteem, but odds ratios were lower than for female students. Conclusions: Present findings warrant attention to propose early interventions targeting sleep and mental health in the university setting taking sex into account.     

Congress Calendar

Background.?Saliva collection is an easy, non-invasive method to measure hormones.

Methods.?Two studies were performed. In the first, a convenience sample of 1454 males who had submitted saliva for salivary testosterone measurements were studied. In the second study, we intensively studied symptoms and measurements of total testosterone, free testosterone symptoms and measurements of total testosterone, free testosterone and bioavailable testosterone in relationship to salivary testosterone in 127 men. A secondary endpoint was to examine the relationship of salivary testosterone to hypogonadal symptoms in the ADAM and AMS questionnaires.

Results.?In the first study, we have shown that salivary testosterone, measured in 1454 males aged 20 to 89 years, declines by 47% over the lifespan. In the second study, salivary testosterone was strongly correlated with bioavailable testosterone (p < 0.000001) calculated free testosterone (p < 0.00001) and total testosterone (p < 0.002). Salivary testosterone was significantly related to hypogonadal symptoms on the St. Louis University ADAM questionnaire and the Aging Male Survey.

Conclusions.?These studies support the use of salivary testosterone as an acceptable assay for screening for hypogonadism. Salivary testosterone is not a better assay than other measures to diagnose hypogonadism.     

Career Adaptability,Resilience, and Life Satisfaction Among Italian and Belgian Middle School Students

Youth need help with planning their future, developing positive life trajectories, and coping with socioeconomic conditions. Using a life design approach, we analyzed the relationship between career adaptability, resilience, and life satisfaction among Belgian (N = 158) and Italian (N = 158) middle school students. We hypothesized that career adaptability, directly and indirectly via resilience, would predict life satisfaction. Furthermore, we predicted that the conceptual model would be comparable between countries. Each participant completed self-report measures to assess career adaptability, resilience, and life satisfaction. The results obtained using a two-step approach to structural equation modeling suggest that career adaptability is directly and indirectly, through resilience, related to students' life satisfaction in both Italian and Belgian students. These results have important implications for supporting middle school students in their life design process.     

A cross-sectional study on the shift work and metabolic syndrome in Japanese male workers

Introduction.?Shift work has been reported to be associated with an increase in the metabolic syndrome (MetS). To clarify the association between the type of shift work and the risk of MetS, a cross-sectional field survey was conducted after adjusting for age and lifestyle factors.

Methods.?The subjects were 3007 Japanese males, aged 34–64 years old, who were employees (1700 day and 1307 shift workers) of a car-manufacturing company. The standard Japanese criteria for the diagnosis of MetS was used. Age, smoking habit, drinking habit, sleeping habit and exercise habit were used as the independent variables.

Results.?The prevalence of MetS in the day workers, two-shift workers, and three-shift workers were 13.8% (234/1700), 10.7% (120/1125) and 17.6% (32/182), respectively. There was a significant difference in the prevalence between the two-shift workers and the day workers. Estimation of the odds ratios (95% confidence intervals) of age, two-shift work and habitual exercise for MetS were 1.03 (1.01–1.04), 0.77 (0.61–0.98) and 0.64 (0.51–0.81), respectively.

Conclusion.?Two-shift work was associated with lower risk of MetS, which is not in accordance with past reports. This finding should therefore be re-analysed, including investigation of the job content in each group.
