Investigation of Internalized Weight-Related Stigma: Progression to Dietary Addiction and the Role of Stress.

ABSTRACT

INTRODUCTION: Internalizing weight stigma can lead to the development of dietary addiction, as individuals seek food as a coping mechanism for the emotional distress caused by stigma. The influence of stress exacerbates this dynamic, encouraging the reliance on food as a stress-coping strategy. METHODS: Electronic questionnaires were completed in a special electronic form through an online platform. The Two-Factor Weight Bias Internalization Scale (WBIS-2F), the Yale Food Addiction Scale (YFAS), the Depression Anxiety Stress Scale-21 (DASS-21), Positive and Negative Affect Schedule (PANAS), the Life Orientation Test (LOT), the Brief Resilience Scale (BRS) were used at this study to examine the prevalence of Internal Weight Stigma (IWS) among adults in Greece, evaluate the degrees of stress/anxiety, food addiction, mental resilience, emotions, and positive life perspectives within this group, and explore the correlations between stress/anxiety, mental resilience, optimistic life attitudes, and both IWS and food addiction. RESULTS: 376 participants completed the questionnaire. The average BMI of the participants was 26.3 kg/m2 (SD = 5.9 kg/m2). Almost half of the participants (46.8%) fell within the normal weight range (18.5 ≤ BMI ≤ 24.9), while 28.2% were classified as overweight and 21.0% as obese. Interestingly, a significant majority (63.1%) perceived themselves as heavier than the normal weight range suggests. Most participants demonstrated typical levels of depression, anxiety, and stress, with percentages of 67.3%, 64.9%, and 71.3%, respectively. Resilience exhibited positive associations with optimism and positive emotions while displaying negative connections with depression, anxiety, stress, and negative emotions. Additionally, individuals with greater optimism reported fewer symptoms of despair, anxiety, and stress. CONCLUSION: The research highlights the intricate dimensions of mental well-being, emphasizing the need for a holistic comprehension encompassing demographic, psychological, and societal factors. The results indicate potential strategies for intervention to boost resilience, and optimism, and tackle issues such as food addiction, underscoring the significance of fostering a positive body image and self-esteem.
