Dietary prevention of cardiovascular risk factors is seldom implemented.
We assessed the dietary changes made by subjects at high risk of cardiovascular disease (CVD).
Cross-sectional, multicentre observational study (European Society of Cardiology - ESC EORP-EUROASPIRE V Primary Care) including 78 centres from 16 ESC countries.
Participants aged 18-79 years, devoid of CVD but treated with antihypertensive and/or lipid-lowering and/or antidiabetic therapy were interviewed >6 months and <2 years after medication initiation. Information regarding dietary management was collected by questionnaire.
2759 participants (overall participation rate 70.2%, 1589 women, 1415 aged ≥60 years, 43.5% with obesity, 71.1% on antihypertensive, 29.2% on lipid-lowering and 31.5% on antidiabetic treatment). Among participants with obesity, 47.7% reported having received dietary advice to lose weight [range: 24.7% (Greece) to 71.8% (Lithuania)]. Among participants on antihypertensive drug therapy, 53.9% reported being on a blood pressure lowering diet [range: 5.6% (UK) to 90.4% (Greece)]; a reduction of salt intake in the last three years was reported by 71.4% [range: 12.5% (Sweden) to 89.7% (Egypt)]. Among participants on lipid-lowering therapy, 56.0% reported being on a lipid lowering diet [range: 7.1% (Sweden) to 90.3% (Egypt)]. Among participants with diabetes, 57.2% reported being on a diet [range: 21.6% (Romania) to 95.1% (Bosnia & Herzegovina)]; a reduction in sugar intake was reported by 80.8% [range: 56.5% (Sweden) to 96.7% (Russian Federation)].
In ESC countries, fewer than 60% of participants at high CVD risk report being on a specific diet, with wide differences between countries.
