Patient information sheet
Condition
Prevention of Cardiovascular diseases
Intervention
1. Medical interventions by GPs: determination of cardiovascular risk using a new computer tool, medical interventions aimed at medical risk factors (e.g. hypertension, high blood glucose level, high cholesterol) and a reduction of overall risk, follow-up dependent on cardiovascular risk
2. Interventions aimed at behaviour change (physical activity, diet, smoking): personalised website with guidelines based on theories on behaviour change + multidisciplinary support based on prinicples from behaviour therapy

Primary outcome measure
1. The effects of medical and behavioural interventions on medical parameters such as systolic blood pressure, diastolic blood pressure, total blood cholesterol level, blood glucose level (HbA1c), overweight and obesity, BMI
2. The effects of medical and behavioural interventions on health related behaviour such as physical activity; fat; fruit and vegetable intake; and smoking behaviour
3. The effects of medical and behavioural interventions on overall cardiovascular risk mediated by changes in medical and/or behavioural risk factors
4. The proportion of study participants with a 10% reduction in systolic blood pressure with participants with hypertension
5. The proportion of study participants with a 10% reduction in diastolic blood pressure with participants with hypertension
6. The proportion of study participants with a 10% reduction in total cholesterol with patients with hypercholesterol
7. The proportion of study participants with a 10% reduction in HB1Ac with initial HB1Ac >7% (high risk)
8. The proportion study participants with a 10% reduction in weight with initial BMI >25 kg/m²
Secondary outcome measures
1. The incidence of cardiovascular events
2. Number and total costs of cardiovascular events leading to loss of productivity
3. The effects of medical and behavioural interventions on psychological constructs as stage of change, attitude towards behaviour, self-identity, perceived behavioural control, autonomous motivation, intention
4. The effects of medical and behavioural interventions on Health Related Quality of Life
5. The effects of social support on health related behaviour (physical activity, fat and fibre intake and smoking behaviour) and psychological constructs (stage of change, attitude towards behaviour, self-identity, perceived behavioural control, autonomous motivation, intention)
6. A cost-effectiveness analysis of the medical and behavioural interventions using incremental cost-effectiveness ratios

Participant exclusion criteria
People with a high cardiovascular risk are not excluded from the PreCardio-study, given the constant supervision GPs and a cardiologist involved in PreCardio. However, high risk participants are advised not to take part in certain rigourous training schemes available to the participants of the study
