Abstract P216: Blood Pressure Level as Predictor for Developing Diabetes Type 2
Introduction and Aim: The link between diabetes type 2 and hypertension is a well established with both factors parts of the metabolic syndrome. Whether hypertension is an independent predictor for diabetes type 2 development has been examined in previous studies, however with divergent findings. The aim of this study was to investigate whether hypertension, including mildly elevated blood pressure within the normal range predicted subsequent development of diabetes type 2 over an extended follow-up.
Methods and Results: Data were derived from participants of the intervention group of the Gothenburg primary prevention study where a random sample of 7333 men aged 47-55 years and free of diagnosed diabetes underwent a screening investigation in 1970 to 1973. During a 32-year follow-up, 956 men (13%) were diagnosed with diabetes according to the Swedish hospital discharge register. Development of diabetes type 2 was positively correlated to age, BMI, systolic blood pressure (SBP) and diastolic blood pressure (DBP), serum cholesterol, hypertension treatment, non-manual occupation, high tobacco use, sedentary lifestyle at the midlife screening. In a Cox regression model which adjusted for BMI and other risk factors we calculated the multiple adjusted hazard ratio for developing diabetes type 2 according to blood pressure level. Compared to a reference level of systolic blood pressure (SBP) below 130 mm Hg, men with SBP of 130-139 mmHg, 140-149 mmHg and > 150 mmHg had a multiple adjusted hazard ratios (HRs) of 1.41 (95% confidence interval) 1.11–1.80), 1.38 (1.08–1.75) and 1.67 (1.35–2.07), respectively. Mid-life diastolic blood pressure over 90 mmHg was associated to an increased risk of developing diabetes type 2 (multiple adjust HRs of 1,60 1,21–2,11)
Conclusion: In this population, at mid-life, hypertension as well as moderately elevated systolic blood pressure levels within the normal range was shown to be independent predictors of diabetes type 2.
