Abstract
Objectives To determine the prevalence of cardiovascular risk factors, evaluate the association between the presence of cardiovascular risk factors and the degree of knowledge about nutrition, and finally to measure the association between the presence of cardiovascular risk factors and dietary control. Method A cross sectional prevalence study was performed in a semirural health area. Data collection was carried out through personal interviews in the homes of 402 individuals aged between 18 and 75 years old. The questionnaire model was obtained from the “Nutritional Evaluation of the Catalan Population”carried out in 1992-1993. This study is part of the more extensive study: “Evaluation of nutritional status in the Health Area of Lleida 2001-2002”. Results Knowledge about diet and its influence on both cholesterol and health in general was good; no significant differences were found between persons with cardiovascular risk factors and those without. Individuals who knew they had one risk factor showed a greater tendency to control their diets but the percentage of individuals doing so was only high among diabetics (71.4%). Individuals with high cholesterol levels who received cholesterol-lowering drugs showed lower dietary control than those not receiving drug treatment (28.6% versus 17.6%). Conclusion The poor dietary control found for some risk factors was not associated with a lack of knowledge but rather to a lack of motivation regarding diet.
