While the prevalence of overweight and obesity is higher among children of some non-Western ethnic minorities than among their Caucasian counterparts, their body image is understudied. The current study examined the body image of Dutch children of non-Western ethnic minorities (i.e., Surinamese, Antillean, Moroccan, and Turkish). Sociocultural influences from school, media and home environments and their perceptions of overweight prevention programs were taken into account. Fifty-two non-Western ethnic minority children (aged 8–12 years) participated in semi-structured interviews and focus groups. Results showed that the children generally underestimated their current body size, which was often overweight, and preferred thin and ‘normal’ body sizes. Results further revealed important insights into culturally determined themes, relating to perceived preferences in media, peers, parents, and teachers, nutritional habits, and children's beliefs about school-based health interventions. We conclude that targeting culturally sensitive awareness about actual body size and healthy body images seems paramount in future interventions.
