OBJECTIVE: To investigate non-urological patients with multiple comorbidities for factors contributing towards differences in testosterone concentration in multiethnic Malaysian men.
DESIGN: An observational study.
PATIENTS: Sexually active men, ≥40 years, with no known urological problems, were recruited at the phlebotomy clinic at our centre.
MEASUREMENTS: A brief history along with latest fasting lipid profile and plasma glucose levels were obtained. An Aging Male Symptoms questionnaire was administered; waist circumference (WC) and serum testosterone concentration were measured.
STATSTICAL ANALYSIS: Analysis of testosterone concentration between Malay, Indian and Chinese men was performed. Statistical tests such as analysis of variance, χ2 test, univariate and multivariable regression were performed. Any p .05). In the multivariable analysis only Malay ethnicity, WC ≥ 90 cm and low high-density lipoprotein (HDL) were associated with lower testosterone concentration.
CONCLUSION: In this study, Malaysian men of Malay origin had lower testosterone concentration compared with Indian and Chinese men. WC and low HDL were also associated with lower testosterone concentrations.
