Brief Summary

Voed je Beter is a randomized, multicenter, controlled trial to examine whether personalized guidance to increase adherence to the Dutch dietary guidelines, compared to usual care, improves health of cardiovascular patients who receive regular medical treatment.

Detailed Description

Voed je Beter is a randomized, multicenter, controlled trial to examine whether a personalized intervention to increase adherence to the Dutch dietary guidelines, compared to usual clinical care, improves health of cardiovascular patients on top of medical treatment.

Patients previously diagnosed with cardiovascular disease are randomized into two parallel groups: the intervention or the usual care group. The intervention consists of personalized guidance from a dietician focussing on improving adherence to the Dutch dietary guidelines during a period of six months. The control group receives usual clinical care.

At baseline, three months, six months, and 12 months measurements will be performed. Primary outcome data will be collected at 6 months. After 12 months, additional data will be collected to assess the prolonged effects of the intervention. The primary outcome of interest is the difference in SMART Risk Score between the intervention and usual care group from baseline till six months.

Secondary outcomes are differences in SMART Risk Score at three months and twelve months; systolic blood pressure, diastolic blood pressure and cardiovascular parameters; diet quality, salt intake, vitamin levels in blood; body weight and waist circumference; renal function; quality of life; sleep; self-efficacy; mental health and medication use. In addition, an economic evaluation is carried out.

Primary Outcome Measures
NameTimeMethod
Second manifestations of arterial disease (SMART) Risk Scorebaseline till six months

Estimate for 10-year risk for recurrent vascular events (range 0-100%), higher scores mean a worse outcome

Secondary Outcome Measures

Anthropometrics -waist circumferencebaseline, three months, six months and twelve months

Waist circumference (in centimeters)

Self-reported quality of lifebaseline, three months, six months and twelve months

36-Item Short Form Health Survey questionnaire, a high score defines a more favorable health state.

Mental status: depression symptomsbaseline, three months, six months and twelve months

The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report screening scale with a score ranging from 0 to 21. Higher scores indicating higher severity of anxiety or depressive symptoms.

Second manifestations of arterial disease (SMART) Risk Scorebaseline till three months, baseline till twelve months

Estimate for 10-year risk for recurrent vascular events (range 0-100%), higher scores mean a worse outcome

Systolic and diastolic blood pressurebaseline, three months, six months and twelve months

Blood pressure measurements following the recommendations for home blood pressure measurement by the European Society of Hypertension, meaning duplicate morning and evening measurements for 7 days.

Diabetic parametersbaseline, three months, six months and twelve months

Insulin and glucose in mmol/L

Diet quality assessed by the Dutch Helathy Diet Index 2015 score (Eetscore-FFQ)baseline, three months, six months and twelve months

Dutch Healthy Diet Index 2015 score (range 0-160 points, higher scores mean better outcome), assessed by a short Food Frequency Questionnaire.

Renal functionbaseline, three months, six months and twelve months

eGFR and albumin/creatinine ratio.

Self-efficacy assessed by the Dutch general self-efficacy scalebaseline, three months, six months and twelve months

Dutch general self-efficacy scale (range 10-40), a higher scores mean a more positive self-efficacy

Single-item on a 7-point Likert scale

Mental status: dispositional optimismbaseline, three months, six months and twelve months

Life Orientation Test-Revised (LOT-R) 10-item questionnaire. The LOT-R sum score that ranges from 0 to 24, with higher scores indicating greater optimism.
