Health-related behavior A comparison of health-related behavior four-months after discharge between groups indicated that diet, medication use and smoking may differ between Type D and non-Type D patients (Table 3). First of all, fish con- sumption was considerably less frequent among Type D patients. A total of 21% of Type D’s consumed fish less than once a week compared to only 5% of non-Type D’s (c 2(1, N = 268) = 16.40; p < 0.001). A trend towards less consumption of fruits and vegetables in Type D patients was found as well, but 81% of non-Type Ds versus 70% of Type Ds consumed fruits and vegetables on a daily bases (c2(1, N = 267) = 3.44, p = 0.064).
