Zusammenfassung

Nutrition behaviors are governed by health beliefs such as risk perceptions, outcome expectancies, and optimistic self-beliefs. This study deals with the role that objective criteria such as age and body weight might play in forming subjective beliefs. The question is whether they can deter people from forming an overly optimistic judgment of their health risk. Six kinds of verbal judgments were assessed, namely self-reported health, vulnerability toward cardiovascular diseases, nutrition outcome expectancies, nutrition self-efficacy, intentions to change one s diet, and reported nutrition behaviors. In a sample of 1,583 men and women between 14 and 87 years of age, these judgments were statistically related to age and body weight. It was found that people do take their objective risk status into account, but only to a certain degree. The self-serving bias continues to exist throughout all age groups and weight levels. Moreover, it was found that individuals report better intentions to adhere to healthy foods and better nutrition behaviors as they grow older and gain weight.
