“…[44][45][46] Therefore, rather than performing biochemical tests alone, studies should use questionnaires such as the Aging Male Symptoms (AMS) since the latter are very useful in treating hypogonadism and examine various clinical symptoms. 47 However, our study did not use AMS to examine TD.…”

Background and objectiveTestosterone deficiency (TD) increases the incidence of cardiovascular risk factors such as diabetes and hypertension. Conversely, TD is reported in people with obesity and diabetes. Therefore, this study examines the relationship between TD, diabetes, and hypertension by following a longitudinal design. Material and methodsIn this study, 2242 (1490 middle-aged and 752 elderly) healthy men were followed up for 8 years and the incidence of hypertension or diabetes was determined.The diagnostic criteria for hypertension were systolic pressure ≥140 mmHg and diastolic pressure ≥90 mmHg, and the criterion for diabetes was a fasting blood glucose level ≥126 mg/dL; the men who took medication for hypertension or diabetes were considered diseased. The threshold for TD was 2.5 ng/mL of serum testosterone. Subsequently, the relative risk (RR) of disease according to the testosterone level was analyzed. In addition, the RR of TD according to glucose and blood pressure levels was analyzed for men with normal testosterone at the initial examination. ResultsThe TD incidence rates were 12.2 and 16.8% for middle-aged and elderly men, respectively. Among the middle-aged men, the diabetes incidence rates were 11.7 and 5.7% in the TD and non-TD (NTD) groups, respectively; the RR of diabetes increased by 1.771 times in the TD group relative to the NTD group (p<0.001). Among the elderly men, the RR of hypertension and diabetes increased by 1.573 and 1.649 times, respectively, in the TD group, compared to the NTD group. Among those with normal testosteroneTestosterone deficiency and hypertension, diabetes e98

“…The AMS scale had internal consistency (α = 0.89 (95% CI 0.88 to 0.90)); the mean alpha estimates across the AMS subscales ranged from 0.79 to 0.82. The AMS scale also had good test-retest reliability (r = 0.85 (95% CI 0.82 to 0.88)); the test-retest reliability coefficients of the AMS subscales ranged from 0.76 to 0.83 66. AMS is a standardised scale according to psychometric norms.…”

Strength training as a supplemental therapy for androgen deficiency of the aging male (ADAM): study protocol for a three-arm clinical trial

et al. 2019

IntroductionAndrogen deficiency of the ageing male is a clinical syndrome resulting from the low production of androgens (testosterone levels <6.9 nmol/L) with symptoms including decline in lean mass, muscle strength, increases in body mass and overall fat mass. The aim of the study is to examine the effect of a 12 week strength training intervention on body composition, physical function, muscle cellular and molecular and selected biochemical markers of metabolic health in hypogonadal patients.Methods and analysisThe study is three-group controlled 12-week experiment to assess the effect of strength training on hypogonadal patients with testosterone replacement therapy and newly diagnosed males without testosterone replacement therapy. Age matched healthy eugonadal males are also engaged in strength training. Lean mass is used to determine sample size indicating, that 22 subjects per group will be sufficient to detect intervention related changes at the power of 0.90. All outcomes are collected before the intervention (pre-intervention assessments) and after the intervention (post-intervention assessments). Clinical outcomes are body composition (lean mass, fat mass and total body mass) measured by dual-energy X-ray absorptiometry, physical functioning assessed by physical tests and psychosocial functioning. The most important haematological and biochemical parameters included are glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, testosterone, luteinizing hormone, follicle-stimulating hormone, sexhormone-binding globulin, insulin and prostate-specific antigen. Muscle cellular and molecular outcomes are muscle fibre size and regulators of muscle fibre size. Muscle cellular outcomes are measured from muscle biopsies obtained from musculus vastus lateralis.Ethics and disseminationThis trial is approved by Ethics Committee of the University Hospital in Bratislava, Slovakia, (ref. trial number: 127/2017) and all subjects will be fully informed on the rationale, risks and benefits of the study and sign the written informed consent prior to entering the study. Results will be published in peer-reviewed journals and presented in scientific conferences.Trial registration numberNCT03282682

A reliability generalization meta-analysis of coefficient alpha and test–retest coefficient for the aging males’ symptoms (AMS) scale

Abstract: The AMS scale and the three subscales had fairly good internal consistency and test-retest reliability. Future psychometric studies of the AMS scale should report important characteristics of the participants, details of item scores, and test-retest reliability.
