Objectives: The ELITE study (German acronym for "Nutrition, lifestyle and individual information for prevention of heart attack, stroke and dementia") prospectively collects data on hypertension, cardiovascular risk factors (RF), dietary habits, physical activity, cognitive function, and quality of life in North-West Germany, which will then be improved through targeted individual information. The aim of the study is to improve the health of the participants in the long term and to identify reasons for a lack of implementation of prevention measures.

Methods: Of 4,602 included subjects, 3,868 could be studied so far at one-year follow-up. Blood pressure (BP) was measured according to the guidelines at admission and blood pressure history, premedication, sports behaviour and BMI were recorded by means of questionnaires and compared with the data collected in the follow-up examination after one year.

Results: The participants were evaluated in 4 groups (G): G1 - normotensive patients (n = 1,558), G2 - controlled hypertensive patients (n = 502), G3 - untreated uncontrolled hypertensive patients (n = 1,080), G4 - treated uncontrolled hypertensive patients (n = 728). In G1 blood pressure (RR) remained unchanged from 126.3/77.8 to 127.8/78.5, in G2 there was a significant (p < 0.001) RR increase from 128.1/77.0 to 134.9/79.8. In G3 and G4 RR decreased significantly (p < 0.001) from 149.9/90.0 to 143.5/86.9 and from 153.1/87.5 to 146.2 84.1 mmHg, respectively. In G3 and G4, RR decreased in 56.1% and 56.3% of subjects and increased in 18% and 21%, respectively. In contrast, RR increase was found more frequently in G1 and G2 (34.3% and 51%, respectively), and RR decrease less frequently (25.4 and 20.7%, respectively). The main reasons for RR decrease were weight loss, more exercise, and more antihypertensives. Frequently, improved compliance and dietary changes were given as reasons. As expected, the opposite often led to RR increase.

Conclusion: 56% of the hypertensive participants succeeded in lowering their blood pressure, whereas there was a significant increase in blood pressure, especially in those who were well controlled with antihypertensives. This underlines the need to further motivate normotensive patients to maintain their normotension. The results show that the combination of individual written education and lifestyle interventions are an effective tool for the public health sector to combat hypertension. In our participants, lifestyle interventions have a significant impact on BP change. It should be noted critically that there are still too many patients who have not been reached.
