Men who are 6 ft tall or taller and have a BMI >30 are more prone to venous thromboembolism (VTE) than their shorter, lighter counterparts, data from a large long-term study conducted in Norway suggest.

Knut H. Borch and colleagues collected weight, height, and other data from 26,714 men and women aged 25 to 97 years. During a median of 12.5 years of follow-up, 461 incident VTE events occurred.

The researchers found that compared with short (5 ft 7.7 in or less) normal-weight men (BMI <25 ) the age-adjusted risk of VTE was:

  • 5.28 times higher in obese and tall (at least 5 ft 11.7 in) men
  • 2.57 times higher in normal-weight and tall men
  • 2.11 times higher in obese and short men

Compared with short (5 ft 2.6 in or less) normal-weight women the age-adjusted risk for VTE was:

  • 2.77 times higher in obese and tall women
  • 1.83 times higher in obese and short women
  • Not increased in normal-weight and tall (more than 5 ft 6 in) women

The findings were published online in Arteriosclerosis, Thrombosis, and Vascular Biology.
