Comparison of age of subjects, BMI, marital status, smoking, snuff, alcohol intake, and biomarkers of systemic inflammation in consider PSA in 119 middle-aged healthy men from the general population.
| Variables | PSA |
||
|---|---|---|---|
| < 2 ng/ml | ≥ 2 ng/ml | ||
| N | 85 | 23 | |
| Age (years) | 54 (± 4.0)* | 57 (± 3.0)* | |
| MBI (kg/m2) | 27 (± 4.0) | 26 (± 3.0) | |
| Marital status | |||
| Married | 67 (89%) | 17 (77%) | |
| Single | 18 (21%) | 5.0 (23%) | |
| Smoking | |||
| Never | 45 (54%) | 12 (52%) | |
| Past/current | 39 (46%) | 11 (48%) | |
| Snuff | |||
| Never | 70 (82%) | 22 (96%) | |
| Past/current | 15 (18%) | 1.0 (4.0%) | |
| Alcohol intake | |||
| 0–50 ml/week | 28 (33%) | 11 (48%) | |
| 60–100 ml/week | 9.0 (11%) | 3.0 (13%) | |
| > 100 ml/week | 48 (56%) | 9.0 (39%) | |
| Biomarkers | |||
| PSA (ng/ml) | 0.9 (± 0.48) | 3.0 (± 1.2) | |
| CRP (mg/l) | 1.8 (± 3.0) | 2.4 (± 3.0) | |
| Fibrinogen (g/l) | 2.4 (± 0.6)** | 2.9 (± 0.9)** | |
N = Number; Values are mean (±SD) or number (%). BMI = body mass index; PSA= prostate-specific antigen; CRP= C - reactive protein. Values with matching superscript signs differ statistically from each other. Statistical analyses were done using the Mann-Whitney U test. P-values below 0.05 are considered statistically significant.
