Research suggests that body dissatisfaction is common among children. However, it remains largely unknown how body dissatisfaction occurs on a daily basis and which environmental factors are linked to this. The purpose of this study was to examine (1) state body dissatisfaction, dietary restraint, compensatory exercise and loss of control eating among children and its association with upward comparisons via social media and (2) whether trust in parents may attenuate this association. Children from 10 to 12 years old (N = 50) were assessed three times a day during a two-week period. Trust was examined via a baseline questionnaire. State body dissatisfaction, dietary restraint, compensatory exercise, loss of control eating and upward comparisons were examined via Ecological Momentary Assessment (EMA). Multilevel analyses indicated that an a higher level of upward comparison is associated with a higher level of state body dissatisfaction, compensatory exercise and loss of control eating. Trust in father significantly moderated the association between appearance comparison and body dissatisfaction. No evidence was found for the protective role of trust in mother. Future research is necessary to enhance our understanding of state body dissatisfaction among children and of environmental factors that may protect children from the adverse effects of social media.

儿童日常生活中的身体不满意和饮食失调症状：父母可以防止社交媒体上的外表比较吗？

研究表明，对身体不满意在儿童中很常见。然而，人们在很大程度上仍不清楚身体不满意是如何每天发生的以及哪些环境因素与之相关。本研究的目的是检查（1）儿童对身体的不满、饮食限制、补偿性运动和饮食失控及其与社交媒体向上比较的关系；（2）对父母的信任是否会减弱这种关联。10 至 12 岁的儿童 (N = 50) 在两周内每天接受 3 次评估。通过基线问卷调查信任度。通过生态瞬时评估（EMA）检查身体不满意、饮食限制、补偿性运动、饮食失控和向上比较。多层次分析表明，较高水平的向上比较与较高水平的身体不满意、代偿性运动和饮食失控有关。对父亲的信任显着调节了外表比较和身体不满意之间的关联。没有发现证据表明对母亲的信任具有保护作用。未来的研究有必要加强我们对儿童对国家机构的不满以及可能保护儿童免受社交媒体不利影响的环境因素的理解。
