Difficulties in changing the diet in relation to dietary fat intake among patients with coronary heart disease.
OBJECTIVE
To study barriers in following nutritional advice among coronary heart disease patients in relation to dietary fat intake.


METHODS
A cross-sectional study using 4-day food records and a questionnaire with regard to barriers to or difficulties in following dietary advice.


METHODS
Altogether, 362 male subjects with coronary heart disease from two separate patient populations (91 + 271) were included in the study, with the mean age of 50 years and 60 years, respectively. The patients were classified into low (< or = 30 E%) or high (> 30 E%) fat intake groups. The patients with low dietary fat intake obtained on an average 10 E% less energy from fat as compared to the high dietary fat intake group.


RESULTS
Overall, most patients with coronary heart disease reported difficulties in following nutritional advice when eating in social situations. Patients with high dietary fat intake reported more frequently than patients with low fat intake that they eat like other people without thinking about what they eat. On the other hand, there were no differences between the high and low fat intake groups in the barriers: eating at work, food price, shopping, taste or knowledge of nutrition.


CONCLUSIONS
Our results suggest that the sensitivity to social influence is an important factor explaining noncompliance with dietary advice among patients with high dietary fat intake.
