title: Fibrinogen, other cardiovascular risk factors and diabetes mellitus in Hong Kong: a community with high prevalence of Type 2 diabetes mellitus and impaired glucose tolerance.
abstract: OBJECTIVE
  To determine the prevalence of Type 2 diabetes mellitus and impaired glucose tolerance (IGT) and their relationships to fibrinogen and other cardiovascular risk factors in Hong Kong Chinese.
  
  
  METHODS
  A probability sample of 1,316 men and 1,348 women aged 25-74 years were examined in a population-based cross-sectional study.
  
  
  RESULTS
  A total of 3.0% (95% confidence interval 2.1-3.9) of men had previously diagnosed (known) and 6.4% (5.0-7.8) newly diagnosed (unknown) diabetes, 14.4% (12.4-16.5) had IGT and 79.2% were normal by 1985 WHO diagnostic criteria; corresponding prevalences in women were 3.7% (2.7-4.7), 5.9% (4.6-7.2), 17% (14.8-19.2) and 73.4%. The age-standardized prevalence of Type 2 diabetes for the 35-64 age group was 9.5% (7.5-11.6) in men and 10.2% (8.0-12.4) in women. Age-adjusted mean fibrinogen levels in these four groups (normal/IGT/unknown diabetes/known diabetes) with decreasing degrees of glucose tolerance (diabetes status) were 2.80, 2.57, 2.51 and 2.47 g/l (P = 0.003) in men, and 2.86, 2.72, 2.67, 2.61 g/l (P = 0.005) in women. Age, obesity, systolic blood pressure and triglycerides were significantly associated with diabetes status in both sexes, fibrinogen in men only and high density lipoprotein cholesterol negatively in women.
  
  
  CONCLUSIONS
  The prevalence of Type 2 diabetes mellitus was very high especially in older subjects, and fibrinogen was associated with increasing glucose intolerance in men but not in women. The detection and better control of cardiovascular risk factors, particularly hypertension in this developed Chinese community with a high prevalence of diabetes and glucose intolerance, is particularly important.
