(PNM-54) Testosterone assessment in patients of the blue bus of Sorocaba - mobile men’s health clinic

Abstract Introduction In Brazil, men have a shorter life expectancy compared to women, primarily due to reduced access to preventive medical care. Consequently, patients are frequently diagnosed at advanced stages of disease. To address this disparity, the Municipal Government of Sorocaba implemented the Blue Bus Project, a mobile outpatient unit dedicated exclusively to men’s health care. The unit travels through multiple regions of the city and provides consultations conducted by urologists, which include physical examination as well as a range of laboratory investigations. Materials and Methods This retrospective cross-sectional study included 150 men. Data collection comprised serum total testosterone (ng/dL) and prostate-specific antigen (PSA, ng/mL) levels. Associations between variables were assessed using Spearman’s rank correlation coefficient, considering both parametric and non-parametric data distributions. Results: >Mean age: 65.6 ± 10.5 years. >Mean total testosterone: 508.9 ± 192.7 ng/dL. >Mean PSA: 2.48 ± 4.08 ng/mL. Spearman’s correlation analysis demonstrated: >Age × Total Testosterone: r = –0.30, p < 0.01. >Age × PSA: r = 0.23, p ≈ 0.01. Conclusions A significant negative correlation was identified between age and serum total testosterone levels, whereas a positive correlation was observed between age and PSA levels. These findings underscore the clinical relevance of monitoring testosterone and PSA in men’s health assessment and may contribute to the development of strategies for early screening and timely intervention. Financing No conflict.
