Abstract

Background: This study examined the time trends of body dissatisfaction and dieting among Japanese adolescents and the possible associated mental health problems.

Methods: Two cross-sectional studies were conducted in 2011 and 2023 in the same 17 schools in one prefecture of Japan. Participants comprised 1865 (a 92.8% response rate) and 1174 (a 71.5% response rate) eighth grade students, who participated in the 2011 and 2023 surveys, respectively. Body dissatisfaction and dieting were assessed via a scale that assesses eating behavior and dieting. Mental health problems were assessed via the Strengths and Difficulties Questionnaire (SDQ).

Results: The total score on items for eating behavior and dieting did not change between 2011 and 2023. Moreover, no significant interaction was observed between gender and years surveyed. The associated factors measured in the SDQ were similar in 2011 and 2023. An item-level analysis revealed an increase in score of items related to dieting, the fear of getting fat, and wanting to lose weight by not eating among male adolescents. Furthermore, among females, an increase was observed in items on experiences of losing weight and a decrease in items related to dissatisfaction with body image.

Conclusions: The extent of body dissatisfaction and dieting remained stable among Japanese adolescents from 2011 to 2023. Those who were dieting or had eating problems reported higher emotional problems. More males reported dieting and fear of getting fat in the 2023 survey than was reported in 2011. Future studies should conduct surveys in Asian countries other than Japan, including low- and middle-income countries.

日本八年级青少年对身体不满和节食的变化及其与心理健康问题的关系:一项为期11年的时间趋势研究
背景:本研究调查了日本青少年对身体不满意和节食的时间趋势,以及可能相关的心理健康问题。方法:分别于2011年和2023年在日本某县17所学校进行了两项横断面研究。参与者包括1865名(92.8%的回复率)和1174名(71.5%的回复率)八年级学生,他们分别参加了2011年和2023年的调查。身体不满意和节食是通过一个评估饮食行为和节食的量表来评估的。通过优势与困难问卷(SDQ)评估心理健康问题。结果:2011年至2023年间,饮食行为和节食项目的总分没有变化。此外,性别和调查年龄之间没有显著的相互作用。SDQ中测量的相关因素在2011年和2023年相似。一项项目水平的分析显示,在男性青少年中,与节食、害怕发胖和想通过不吃东西来减肥有关的项目得分有所增加。此外,在女性中,关于减肥经历的条目增加了,而与对身体形象不满意相关的条目减少了。结论:2011 - 2023年,日本青少年对身体不满和节食的程度保持稳定。那些正在节食或有饮食问题的人报告了更高的情绪问题。与2011年的调查相比,2023年的调查中有更多的男性表示节食和害怕变胖。未来的研究应该在日本以外的亚洲国家进行调查,包括低收入和中等收入国家。

期刊介绍: Child and Adolescent Psychiatry and Mental Health, the official journal of the International Association for Child and Adolescent Psychiatry and Allied Professions, is an open access, online journal that provides an international platform for rapid and comprehensive scientific communication on child and adolescent mental health across different cultural backgrounds. CAPMH serves as a scientifically rigorous and broadly open forum for both interdisciplinary and cross-cultural exchange of research information, involving psychiatrists, paediatricians, psychologists, neuroscientists, and allied disciplines. The journal focusses on improving the knowledge base for the diagnosis, prognosis and treatment of mental health conditions in children and adolescents, and aims to integrate basic science, clinical research and the practical implementation of research findings. In addition, aspects which are still underrepresented in the traditional journals such as neurobiology and neuropsychology of psychiatric disorders in childhood and adolescence are considered.
