Role of diet and lifestyle in the prevention of cardiovascular disease: knowledge and attitude of physicians and patients in Southern Italy.
BACKGROUND
The present study aimed to investigate the knowledge and attitude of family physicians and their patients respectively in prescribing and adopting lifestyle and dietary changes in order to prevent cardiovascular disease which is the main cause of mortality in the industrialized Western countries.


METHODS
All physicians working in two suburban areas of Naples and in the city of Avellino were invited to participate in the study and 63% accepted (n = 218). A sample of lay people living in the same areas was randomly selected and 59% accepted (n = 267). Two different questionnaires were used to assess the knowledge and attitudes of physicians and lay people about the role of nutrition and lifestyle in the prevention of cardiovascular risk.


RESULTS
Physicians showed satisfactory knowledge and a good attitude to non-pharmacological prevention--particularly secondary prevention--of cardiovascular disease. The opinions of the lay people interviewed on the impact of lifestyle changes on cardiovascular disease prevention were similarly satisfactory although some inconsistencies were noted.


CONCLUSIONS
In spite of the good propensity of both physicians and their patients to the implementation of lifestyle changes, it appears that dietary modifications prescribed by physicians are not accurately followed or even misunderstood by their patients. This suggests the need of implementing further educational programs.
