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.     

Hormone profiles,body mass index and aging male symptoms: results of the Androx Vienna Municipality study

Aging in the male is accompanied by steroid hormonal decline, and men may develop symptoms associated with hypogonadism. Increased awareness of ‘andropause’ in recent years has led to greater demand for hormonal assessments, resulting in a rising burden for health economics. We conducted a cross-sectional study to define men at risk for hypogonadism, in whom further hormonal investigation should be performed.

We examined 664 blue-collar workers aged 40–60 years at their workplace and determined hormonal status and body mass index (BMI). Men with an abnormal urogenital status and those on medication that might affect endocrine status were excluded from the study. All participants completed the validated Aging Male Symptom (AMS) questionnaire and obtained scores for psychological symptoms, somatovegetative symptoms, and sexual symptoms.

Multiple logistic regression analyses revealed a significantly increased risk (represented by the odds ratio) of psychological symptoms for men with low levels of testosterone and/or bioavailable testosterone (BAT). Increased BMI as well as low testosterone levels and/or low BAT levels raised the risk of somatovegetative symptoms. Each decrease of BAT by 1?ng/ml caused an approximately 1.8-fold increase of the risk (odds ratio?=?1.832, p?=?0.005). Additional independent risk factors were increased age and low luteinizing hormone (LH) level. Men aged 55 years with BMI >?28?kg/m² and with somatovegetative symptoms and moderate or severe psychological symptoms had a 7.2-fold increase in the risk of a BAT level <?1.5?ng/ml compared to men without these risk factors (p <?0.001). Sensitivity and specificity were 75% and 71%, respectively.

The AMS score combined with age and BMI provides an easy and convenient method to identify men with probable androgen deficiency who require hormonal assessment.
