摘要：We investigated the relationship between body mass index (BMI) and personality traits, socioeconomic status (SES), and body image (BI) at the beginning of preadolescence. Data were collected from 238 Italian children aged 10–11 years using self-report scales. Information about SES was derived from parental education and professional status. BI was the variable the most strongly associated with BMI. Controlling for BI, SES, and gender, Agreeableness was inversely associated with BMI, whilst Extroversion was related to BMI in girls only. Gender did not moderate the associations between BI and BMI at this age. The relationship of certain personality traits with BMI is likely to emerge during preadolescence. Early interventions to reduce overweight and obesity could consider the interplay of Agreeableness and Extroversion with gender, BI, and SES.
