Effects of perceived weight discrimination on willingness to adopt unhealthy behaviours: influence of genomic information

Objective: Weight-based discrimination negatively influences health, potentially via increased willingness to engage in unhealthful behaviours. This study examines whether the provision of genomic obesity information in a clinical context can lead to less willingness to engage in unhealthy eating and alcohol consumption through a mediated process including reduced perceptions of blame and discrimination.Design: A total of 201 overweight or obese women aged 20–50 interacted with a virtual physician in a simulated clinical primary care environment, which included physician-delivered information that emphasised either genomic or behavioural underpinnings of weight and weight loss.Main Outcome Measures: Perceived blame and weight discrimination from the doctor, and willingness to eat unhealthy foods and consume alcohol.Results: Controlling for BMI and race, participants who received genomic information perceived less blame from the doctor than participants who received behavioural information. In a serial mul...
