Abstract

Background: Twenty-four-hour movement behaviours-physical activity (PA), sleep and screen time (ST)-are key determinants of child health, yet evidence in Latin American preschoolers remains limited. This study examined associations between these behaviours and physical fitness in Uruguayan preschool children.

Methods: Children (n = 135, 3-4 years) from Rivera, Uruguay, were recruited. PA and sleep were assessed via accelerometry (ActiGraph GT3X-BT); ST was parent-reported. Fitness was evaluated using SUNRISE and PREFIT batteries (strength, power, balance and cardiorespiratory fitness). Regression models adjusted for age and sex were applied.

Results: In the full sample, ST was negatively associated with handgrip strength (β_std = -0.154, p = 0.019) and standing long jump (β_std = -0.168, p = 0.013). PA and sleep showed no significant associations with fitness. Sex-stratified analyses revealed different patterns: In boys, moderate-to-vigorous PA was positively associated with standing long jump (β_std = 0.194, p = 0.038), and ST was negatively associated with handgrip strength (β_std = -0.190, p = 0.034). No significant associations were observed in girls (p > 0.05).

Conclusion: ST was most consistently associated with poorer muscular fitness in preschoolers. Sex-specific patterns suggest the need for tailored interventions, while universally prioritising the reduction of screen time exposure during early childhood.

乌拉圭学龄前儿童24小时运动行为指南与身体健康的关系

背景：24小时运动行为——身体活动（PA）、睡眠和屏幕时间（ST）——是儿童健康的关键决定因素，但拉丁美洲学龄前儿童的证据仍然有限。本研究调查了乌拉圭学龄前儿童这些行为与身体健康之间的关系。方法：招募来自乌拉圭Rivera的儿童（n = 135, 3-4岁）。通过加速度计（ActiGraph GT3X-BT）评估PA和睡眠；ST由家长报告。使用SUNRISE和PREFIT电池（力量、能量、平衡和心肺健康）评估健康状况。采用年龄和性别调整后的回归模型。结果：在全样本中，ST与握力（βstd = -0.154, p = 0.019）和立定跳远（βstd = -0.168, p = 0.013）呈负相关。PA和睡眠与健康没有显著关联。性别分层分析显示了不同的模式：在男孩中，中等至剧烈的PA与立定跳远呈正相关（βstd = 0.194, p = 0.038）， ST与握力呈负相关（βstd = -0.190, p = 0.034）。在女孩中未观察到显著相关性（p < 0.05）。结论：ST与学龄前儿童较差的肌肉健康最一致相关。性别不同的模式表明，需要有针对性的干预措施，同时普遍优先考虑减少儿童早期的屏幕暴露时间。

期刊介绍： Child: care, health and development is an international, peer-reviewed journal which publishes papers dealing with all aspects of the health and development of children and young people. We aim to attract quantitative and qualitative research papers relevant to people from all disciplines working in child health. We welcome studies which examine the effects of social and environmental factors on health and development as well as those dealing with clinical issues, the organization of services and health policy. We particularly encourage the submission of studies related to those who are disadvantaged by physical, developmental, emotional and social problems. The journal also aims to collate important research findings and to provide a forum for discussion of global child health issues.
