Implicit and explicit attitudes to high- and low-calorie food in females with different BMI status.
The study compared implicit and explicit attitudes to three types of foods (high-calorie non-sweet HCNS, high-calorie sweet HCS and low-calorie LC) among females varying in BMI status. Eight three participants completed an affective priming task (implicit attitudes), followed by explicit rating of food images. The results of ANOVA showed a significant difference in implicit attitudes to different types of food, F(3,246)=3.90, p<.01 and the difference among BMI groups (F(6, 213)=2.15, p<.05). The implicit attitudes to HCS were positive in the healthy-weight and overweight groups but negative in obese; the reversed pattern was revealed in attitudes to HCNS. All groups showed negative implicit attitudes to LC foods. The ANOVA performed on explicit ratings revealed a significant effect of food type (F(3,213)=22.54, p<001) but no interaction between food type and BMI status. All participants rated HCNS significantly lower than HCS and LC foods. Our results indicate dissociation in implicit and explicit attitudes to foods among BMI groups, especially in attitudes to HCNS and HCS foods.
