They found that the median age for diagnosis of BPH was 58.6 years. Increasing age, height and fasting blood sugar levels were linked to increased risk of BPH. Greater systolic blood pressure, though associated with other health problems, appeared to lower the risk.
Several previous studies have found overweight or obesity to be a risk factor for BPH, but this one did not. Nor did metabolic syndrome, levels of blood fats or levels of thyroid hormones appear to play a role.
Previous research has linked hyperglycemia to BPH, but the association with height may be a new finding.
"It is entirely plausible that taller men have proportionally larger prostates. Thus, a positive relationship between height and BPH is not unexpected and is biologically plausible," the researchers wrote.
The study was reported in a recent issue of the journal Urology.
