Sleep and Testosterone: Dual Drivers of Psoriasis Risk in Men: Study

Men with low testosterone levels below 300 ng/dL are twice as likely to develop psoriasis (OR 2.97), while sleep less than 7 hours was associated with a 76% higher risk, according to NHANES data. Risk diminished at very low testosterone levels and beyond 8 hours of sleep, highlighting hormonal balance and sleep as modifiable risk factors in psoriasis prevention.

Psoriasis is a chronic, multisystemic immune-mediated inflammatory disorder with a complex etiology involving genetic, environmental, and systemic factors. Testosterone, a key androgen hormone, has immunomodulatory effects, and its deficiency is linked to increased inflammation. Sleep disturbances are also known to exacerbate systemic inflammation. This study investigates the associations between low testosterone levels, short sleep duration, and psoriasis risk using data from the US National Health and Nutrition Examination Survey (NHANES) 2011– 2014. This cross-sectional study included 4,060 male participants, after excluding individuals with missing data on psoriasis, testosterone, sleep duration, and relevant covariates. Psoriasis status was self-reported, testosterone levels were measured using isotope-dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS), and sleep duration was assessed through a self-reported questionnaire. Multivariable logistic regression models were used to estimate the associations between testosterone levels, sleep duration, and psoriasis risk. Restricted cubic spline (RCS) analysis explored potential non-linear relationships, and subgroup and sensitivity analyses were performed to test the robustness of the findings. Results: Participants with testosterone levels below 300 ng/dL had a significantly higher risk of psoriasis (OR=2.97, 95% CI: 2.16– 4.09, P< 0.001) in the fully adjusted model. Short sleep duration (< 7 hours) was also associated with increased psoriasis risk (OR=1.76, 95% CI: 1.33– 2.35, P< 0.001). The RCS analysis revealed a non-linear association between both testosterone levels and sleep duration with psoriasis risk, with risk plateauing at extremely low testosterone levels and sleep durations longer than 8 hours. Sensitivity analysis excluding participants with testosterone levels > 1000 ng/dL confirmed the robustness of these associations. Low testosterone levels and short sleep duration are independently associated with an increased risk of psoriasis in a large, diverse male population. These findings highlight the importance of hormonal and lifestyle factors in the prevention and management of psoriasis, suggesting potential intervention points for improving patient outcomes.

Unhealthy Lifestyle, Chronic Illnesses, and Mental Health Issues Linked to Greater BPH Severity in Elderly Chinese Men: Study

China: A recent study published in Frontiers in Medicine highlights a significant relationship between the severity of lower urinary tract symptoms/benign prostatic hyperplasia (LUTS/BPH) and lifestyle choices, the presence of multiple chronic conditions, and mental health status among older Chinese men. Conducted by Yifan Wu and colleagues from the Department of Urology, Jiangnan University Medical Center, Wuxi, China, the research emphasizes the importance of a holistic approach to managing LUTS/BPH.  

The study examined how various lifestyle and health-related factors affect the intensity of LUTS/BPH symptoms in elderly individuals and provided evidence-based insights for developing integrated intervention strategies. A total of 806 men aged 60 years and above, all diagnosed with LUTS/BPH, were assessed using the International Prostate Symptom Score (IPSS) and categorized into mild and moderate-to-severe groups.

Participants provided comprehensive data on demographics, clinical parameters, lifestyle habits, existing chronic diseases, and mental health conditions such as anxiety, depression, and sleep quality. A binary logistic regression model was used to evaluate how these variables influenced the severity of BPH symptoms.

The following were the key findings of the study:

  • Individuals with moderate-to-severe LUTS/BPH symptoms were more likely to smoke, follow unhealthy diets, and lead sedentary lifestyles.
  • They were also more commonly affected by multiple chronic illnesses and mental health issues, such as depression and poor sleep quality.
  • After adjusting for factors like age, disease duration, prostate volume, PSA levels, and other lab markers, lifestyle and health variables still showed strong links to symptom severity.
  • Current smoking nearly doubled the risk of severe LUTS/BPH (OR = 1.995).
  • Lack of regular physical activity also nearly doubled the risk (OR = 1.996).
  • Unhealthy dietary habits were significantly associated with increased symptom severity (OR = 1.590).
  • The absence of heart disease was linked to a lower risk of severe symptoms (OR = 0.435).
  • A normal lipid profile was associated with reduced severity (OR = 0.587).
  • Not having diabetes was linked to a decreased risk (OR = 0.523).
  • The absence of depressive symptoms was associated with less severe LUTS/BPH (OR = 0.447).
  • Good sleep quality was also linked to a lower risk of severe symptoms (OR = 0.494).

The authors emphasized that while their study offers valuable insights, it also has limitations. It was conducted at a single urban hospital, which may limit the broader applicability of the findings. Additionally, being observational, the study does not establish direct cause-and-effect relationships. Some participants with severe psychiatric conditions were excluded to avoid confounding effects from medications like antidepressants, which can influence urinary function.

The authors concluded that the findings underscore the importance of addressing not only the physical symptoms of benign prostatic hyperplasia but also the associated lifestyle and mental health factors.

They emphasized the need for a collaborative approach involving hospitals and community-based care systems to encourage healthy behaviors, manage coexisting chronic conditions, and develop personalized treatment strategies. Additionally, they recommended conducting future multicenter studies across diverse populations to validate the results and support the development of more comprehensive and inclusive care models.
