title: Link between hypertension and diabetes mellitus epidemiological study of Chinese adults in Taiwan.
abstract: OBJECTIVE
  To elucidate the relationship between hypertension and non-insulin-dependent diabetes.
  
  
  METHODS
  The study consisted of a random sample of adults aged greater than or equal to 40 yr from the Ta-An district of Taipei City and 5 of 12 villages of Taiwan province, which had established primary health-care centers since 1984. A total of 11,478 subjects were recruited into the survey with a response rate of 65.3 and 72%, respectively. Blood glucose and blood pressure levels were measured, and a structured questionnaire was given to each participant. Those identified as having diabetes received further blood tests for lipids and creatinine and were evaluated for vascular complications.
  
  
  RESULTS
  The age- and sex-adjusted prevalence of hypertension among diabetic subjects was twice that of nondiabetic subjects (30.6 vs. 16.4%, P less than 0.0005). Hypertensive subjects had a higher prevalence of diabetes than normotensive subjects (10.2 vs. 4.9%, P less than 0.0005). Among hypertensive subjects, the prevalence of diabetes was 12.7% for those taking antihypertensive drugs and 9.1% for those not taking any drug (P less than 0.05). The prevalence of diabetes significantly increased as mean arterial pressure rose, whether the subjects were stratified by various factors. Multiple regression analysis, including sex, age, body mass index, and other risk factors as independent variables, also showed a significant association between diabetes and hypertension.
  
  
  CONCLUSIONS
  The univariate and multivariate analyses revealed that there seemed to be a tight link between hypertension and non-insulin-dependent diabetes. Family history of diabetes, diabetes duration, diabetes regimen, control of blood glucose, and the presence of nephropathy, as attested by proteinuria, did not contribute to the risk of hypertension. Further studies are necessary to determine whether these two conditions are causally related.
