Benign prostatic enlargement is not associated with diabetes: a population-based study.

Area of Science:

• Urology
• Endocrinology
• Epidemiology

Background:

• The relationship between diabetes mellitus and benign prostatic hyperplasia (BPH) is not definitively established.
• Benign prostatic enlargement (BPE) is a common condition in aging men, and its association with comorbidities like diabetes requires further investigation.

Purpose of the Study:

• To investigate the association between a prior diagnosis of diabetes and the presence of benign prostatic enlargement (BPE).
• To analyze the impact of sociodemographic factors and comorbidities on the potential link between diabetes and BPE.

Main Methods:

• A case-control study design was employed using data from Taiwan's Longitudinal Health Insurance Database 2000.
• 20,152 patients with BPE (cases) were matched with 20,152 patients without BPE (controls) based on age.
• Conditional logistic regression analysis was used to calculate odds ratios (OR) and 95% confidence intervals (CI), adjusting for multiple variables.

Main Results:

• Initially, a higher prevalence of prior diabetes was observed in BPE cases (25.3%) compared to controls (21.8%) (p < 0.001).
• The unadjusted odds ratio for prior diabetes in BPE cases was 1.21 (95% CI = 1.15-1.27).
• After adjusting for factors including geographic region, income, urbanization, hypertension, coronary heart disease (CHD), hyperlipidemia, tobacco use disorder, and obesity, the association between prior diabetes and BPE was not statistically significant (OR = 1.03, 95% CI = 0.98-1.08).
• Hypertension (OR=1.25), CHD (OR=1.40), and hyperlipidemia (OR=1.30) were significantly associated with BPE.

Conclusions:

• The study concludes that a prior diagnosis of diabetes is not significantly associated with benign prostatic enlargement (BPE) when sociodemographic characteristics and common comorbidities are considered.
• Comorbidities such as hypertension, coronary heart disease, and hyperlipidemia demonstrated significant associations with BPE, highlighting their importance in the condition's multifactorial nature.
