Purpose: To examine obesity stigma among nutritional science students and its relationship with eating attitudes and body image.
Background: Obesity stigma has been less recognized in Japan due to the low obesity rate compared to Western countries. However, the 2020 Joint Consensus Statement highlighted the global prevalence of weight stigma, including in healthcare, urging its elimination. Despite this, bias among healthcare professionals remains significant - studies show over 50% of physicians perceive patients with obesity as noncompliant, while 40% of medical students exhibit unconscious bias. Similar trends have been reported among nurses. Obesity stigma discourages medical care-seeking due to distrust in healthcare and exacerbates body dissatisfaction, leading to low self-esteem, depression, anxiety, social isolation, and substance abuse. While physicians and nurses have been studied, research on obesity stigma in nutrition-related professions is scarce, with no studies in Japan. Understanding obesity stigma among nutritional science students - future dietitians - will provide valuable insights for educational programs and contribute to clarifying its mechanisms by analyzing eating attitudes and body image.
