title: Relationship between abdominal obesity, platelet blood count and mean platelet volume in patients with metabolic syndrome.
abstract: OBJECTIVE
  There is evidence that patients with the metabolic syndrome have altered platelet indices including higher mean platelet volume. According to the 2009 International Diabetes Federation criteria of metabolic syndrome diagnosis, elevated waist circumference (≥94 cm in M, ≥80 cm in F), as a determinant of abdominal obesity, is not an obligatory component. The aim of this study was to evaluate the relationship between platelet indices, including mean platelet volume, and abdominal obesity in patients with metabolic syndrome.
  
  
  METHODS
  382 consecutive patients were enrolled in the study and divided into three groups: group A, 218 patients with metabolic syndrome and abdominal obesity (132 M, mean age 65.3 ± 10.9 yrs); group B, 35 patients with metabolic syndrome without abdominal obesity (28 M, mean age 63.3 ± 11.2 yrs); and, group C, 129 patients without metabolic syndrome and without abdominal obesity (99 M, mean age 62.2 ± 13.8 yrs).
  
  
  RESULTS
  In group A, mean platelet volume was significantly higher than in group C (10.70 ± 1.01 vs. 10.35 ± 0.94 fL, p = 0.007). However, there was no difference in mean platelet volume between group A and B (10.70 ± 1,01vs. 10.63 ± 1.03 fL, p >0.05). Furthermore, in group A, mean platelet volume was correlated with waist circumference (r = 0.14, p = 0.041) and body mass index (r = 0.14, p = 0.045). In all study groups, a significant association between mean platelet volume and platelet count (r = -0.33, p <0.001) was found.
  
  
  CONCLUSIONS
  In individuals with metabolic syndrome and abdominal obesity mean platelet volume is positively correlated with waist circumference and significantly higher than in patients without these abnormalities.
