背景:身体不满与不良的心理和身体健康有关,尤其是年轻人。然而,关于各国对体型的认知和与不满意相关的因素的数据有限。
目的:本研究调查了6个国家青年的不满患病率以及与社会人口统计学和社交媒体使用的关联。
方法:重复进行全国横断面在线调查,作为2019年和2020年国际食品政策研究青年调查的一部分。
方法:样本包括来自澳大利亚的21,277名10-17岁青年,加拿大,智利,墨西哥,联合王国,和美国。通过参加尼尔森消费者见解全球小组及其合作伙伴小组的父母/监护人,招募了年轻人来完成在线调查。
方法:图形绘画尺度评估自我感知和理想的身体图像,代表身体不满的量表之间的差异。
方法:多项逻辑回归模型检查了不同国家/地区的身体不满差异,以及与社会人口统计学和社交媒体“屏幕时间”或使用的平台的关联,包括与国家的双向互动。
结果:总体而言,大约45%的年轻人报告了相同的感知和理想的体型,而35%的人“比理想”大”(从加拿大和澳大利亚的33%到智利的42%),20%的人“比理想”薄”(从智利的15%到墨西哥的22%)。更长的社交媒体屏幕时间与“比理想薄”的中度至重度不满的可能性更高,至少对“比理想大”的轻度不满(所有对比p<0.003),YouTube和Snapchat的用户比非用户更不满意(两者对比p≤0.005)。观察到年龄不同国家之间身体不满的适度差异,种族,身体质量指数,和基于重量的戏弄。
结论:身体不满在不同国家的年轻人中普遍存在。这些发现强调了在青少年中促进健康身体形象的必要性,尤其是社交媒体用户。
BACKGROUND: Body dissatisfaction is associated with poor psychological and physical health, particularly among young people. However, limited data exist on body size perceptions across countries and factors associated with dissatisfaction.
OBJECTIVE: This study examined dissatisfaction prevalence and associations with sociodemographics and social media use among youth in six countries.
METHODS: Repeat cross-sectional national online surveys were conducted as part of the 2019 and 2020 International Food Policy Study Youth Survey.
METHODS: The sample included 21,277 youth aged 10-17 from Australia, Canada, Chile, Mexico, the United Kingdom, and the United States. Youth were recruited to complete the online survey through parents/guardians enrolled in the Nielsen Consumer Insights Global Panel and their partners\' panels.
METHODS: Figural drawing scales assessed self-perceived and ideal body images, with differences between scales representing body dissatisfaction.
METHODS: Multinomial logistic regression models examined differences in body dissatisfaction by country, and associations with sociodemographics and either social media \'screen time\' or platforms used, including 2-way interactions with country.
RESULTS: Overall, approximately 45% of youth reported the same perceived and ideal body sizes, while 35% were \'larger than ideal\' (from 33% in Canada and Australia to 42% in Chile) and 20% were \'thinner than ideal\' (from 15% in Chile to 22% in Mexico). Greater social media screen time was associated with a higher likelihood of moderate-severe dissatisfaction for being \'thinner than ideal\' and at least mild dissatisfaction for being \'larger than ideal\' (p<0.003 for all contrasts), with greater dissatisfaction among users of YouTube and Snapchat than non-users (p≤0.005 for both contrasts). Modest differences in body dissatisfaction between countries were observed for age, ethnicity, body mass index, and weight-based teasing.
CONCLUSIONS: Body dissatisfaction is prevalent among youth across diverse countries. These findings highlight the need to promote healthy body image in youth, particularly among social media users.
