Abstract
Factors influencing compliance with dietary advice were investigated in the Diet and Reinfarcation Trial (DART). In terms of achieved intakes, smokers had a lower mean P/S ratio and fibre intake than non‐smokers; manual workers had a lower mean fibre intake than non‐manual workers; and obese men had a higher percentage of energy from fat and lower P/S ratio than non‐obese men. However the effect of the advice (difference in intakes of those advised and thosen not advised) was similar in smokers and non‐smokers and was similar in all social classes. The effect of fat advice was less among obese men than among non‐obese men, probably as a result of weight‐reducing advice given to all overweight men. Fat advice tended to have a greater effect among those who gave up smoking after their heart attack than among non‐smokers and those who continued to smoke but the difference was not statistically significant. This suggests that advice on diet and smoking can be given simultaneously and still be effective.
