The purpose of this study was to examine whether meeting movement behavior recommendations (i.e., ≥60 min of moderate-to-vigorous physical activity [MVPA] per day, ≤2 h of recreational screen time per day, and between 9 and 11 h of nightly sleep), and combinations of these recommendations, are associated with dietary patterns of children. This cross-sectional study was conducted between 2011 and 2013 and included 5873 children 9-11 years of age from 12 countries around the world. MVPA and nightly sleep duration were measured using 24-hour waist-worn accelerometry. Screen time habits were assessed via self-report. A food frequency questionnaire was used to assess dietary patterns, and the whole diet was described by two components derived from principal component analysis: "healthy" and "unhealthy" dietary pattern scores. Covariates included in the multilevel statistical models included age, sex, highest parental education, and body mass index z-score. A healthier dietary pattern score was observed when more movement behavior recommendations were met. Among the three movement behaviors, limiting screen time habits to the recommended amount was most strongly associated with healthier dietary patterns. Similarly, a less unhealthy dietary pattern was observed when more movement behavior recommendations were met. Surprisingly, the highest unhealthy dietary pattern was associated with children meeting the MVPA recommendation alone. Combinations including ≤2 h of screen time per day were those most strongly associated with a less unhealthy dietary pattern. Findings were similar across study sites and in boys and girls. In conclusion, meeting more movement behavior recommendations is generally associated with better dietary patterns in children from around the world, with limiting screen time habits showing the strongest relationships.
本研究旨在探讨儿童是否满足运动行为建议(即每天进行≥60 分钟的中等到剧烈身体活动[MVPA]、每天娱乐性屏幕时间≤2 小时、每晚睡眠时间 9-11 小时),以及这些建议的组合与儿童的饮食模式是否相关。这项横断面研究于 2011 年至 2013 年期间在全球 12 个国家进行,共纳入 5873 名 9-11 岁的儿童。MVPA 和夜间睡眠时间通过 24 小时腰部佩戴的加速度计进行测量。屏幕时间习惯通过自我报告进行评估。使用食物频率问卷评估饮食模式,通过主成分分析得出两个组成部分来描述整个饮食:“健康”和“不健康”饮食模式评分。多水平统计模型中包含的协变量包括年龄、性别、父母最高教育程度和体重指数 z 分数。当满足更多运动行为建议时,观察到更健康的饮食模式评分。在三种运动行为中,将屏幕时间习惯限制在推荐量内与更健康的饮食模式相关性最强。同样,当满足更多运动行为建议时,观察到较少不健康的饮食模式。令人惊讶的是,最高的不健康饮食模式与仅满足 MVPA 建议的儿童相关。包括每天屏幕时间≤2 小时的组合与较少不健康的饮食模式相关性最强。研究结果在各个研究地点以及男孩和女孩中均相似。总之,在全球范围内,满足更多运动行为建议通常与儿童更好的饮食模式相关,限制屏幕时间习惯与饮食模式的相关性最强。
