Grounded in intersectionality theory, this study examined the 6-year prevalence trend and correlates in meeting Canada's 24-Hour Movement Guidelines (Guidelines hereafter) in a nationally representative adolescent samples of South Korea (officially the Republic of Korea).
Self-reported, annually repeated cross-sectional data collected between 2013 and 2018 were used (n = 372,433, 12-17 years old, 47.9% females). Adolescents were categorized as meeting or not meeting different sets of physical activity, screen time (ST), and sleep recommendations within the Guidelines, separately for weekdays and weekend days. Intersectional correlates included sex and social class (i.e., family economic status, parental education level, and academic performance). Multiple logistic regression analyses were performed.
Overall, the proportion of adolescents meeting physical activity, ST, and sleep recommendations were 5.3%, 60.3%, and 10.2% on weekdays and 5.3%, 28.2%, and 46.4% on weekend days, respectively. Between 2013 and 2018, no substantial changes were observed for meeting the physical activity or sleep recommendation, while meeting the ST recommendation was markedly lower in 2018. The proportion of meeting all 3 recommendations were 0.5% for weekdays and 0.8% for weekend days. Overall, compared to female adolescents, male adolescents were consistently associated with more favorable patterns of meeting different sets of recommendations, regardless of social class. Among females only, social class appeared to be not important or even detrimental in meeting different sets of recommendations. Being male, compounded with social class, was associated with meeting the ST recommendation.
Less than 1% of Korean adolescents met the overall Guidelines. Intersectionality-based analysis and intervention may be important in promoting healthy active lifestyles among South Korean adolescents.
本研究基于交叉性理论，考察了韩国具有代表性的青少年样本中，6 年来符合加拿大 24 小时运动指南（以下简称“指南”）的流行趋势及其相关因素。
本研究使用了 2013 年至 2018 年期间每年重复的横断面数据（n=372433 名，年龄在 12-17 岁之间，女性占 47.9%）。青少年被分为符合或不符合指南中不同的体力活动、屏幕时间（ST）和睡眠建议的类别，分别针对工作日和周末。交叉相关因素包括性别和社会阶层（即家庭经济状况、父母教育水平和学业成绩）。采用多因素逻辑回归分析。
总体而言，在工作日，符合体力活动、ST 和睡眠建议的青少年比例分别为 5.3%、60.3%和 10.2%，周末分别为 5.3%、28.2%和 46.4%。2013 年至 2018 年期间，符合体力活动或睡眠建议的比例没有明显变化，而符合 ST 建议的比例在 2018 年显著降低。符合所有 3 项建议的比例在工作日为 0.5%，周末为 0.8%。总体而言，与女性青少年相比，无论社会阶层如何，男性青少年更符合不同建议的组合模式。仅在女性青少年中，社会阶层对符合不同建议的作用似乎并不重要，甚至是有害的。男性，加上社会阶层，与符合 ST 建议有关。
不到 1%的韩国青少年符合总体指南。基于交叉性的分析和干预措施可能对促进韩国青少年健康的积极生活方式很重要。
