背景：来自澳大利亚、加拿大、英国和美国的四个专家小组发布了非常相似的幼儿体育活动（PA）建议。本研究的目的是在两个独立的学龄前儿童样本中确定新的PA指南（定义为总PA的15min/hr）的依从性。方法：我们对南卡罗来纳哥伦比亚学龄前儿童进行了横断面研究。一个样本中共有286名儿童参加，第二个样本中有337名儿童参加。主要结果是通过加速度计测量的总PA（轻度、中度和剧烈强度活动的总和）。两个样本都符合PA指南。对于每个样本，分别使用混合逻辑模型来确定基于性别、种族/民族、父母教育和体重状况的群体之间对PA指南的依从性是否存在差异，并控制学前教育。结果：第一个和第二个样品的总PA分别为14.5和15.2min/hr。在第一个和第二个样本中，符合PA指南的患病率分别为41.6%和50.2%。在这两个样本中，第一个和第二个样本中符合指南的男性多于女性（53.5%对33.5%，57.6%对45.9%）
Background: Four expert panels from Australia, Canada, the United Kingdom, and the United States issued physical activity (PA) recommendations for young children that are quite similar. The aim of this study was to determine compliance with the new PA guideline (defined as 15min/hr of total PA) in two independent samples of preschool children.Methods: We conducted a cross-sectional study of children attending preschools in Columbia, South Carolina. A total of 286 children in one sample and 337 children in a second sample participated. The main outcome of interest was total PA (sum of light, moderate, and vigorous intensity activity) measured by accelerometry. Compliance with the PA guideline was determined for both samples. Separately for each sample, mixed logistic models were used to determine whether there were differences in compliance with the PA guideline between groups based on sex, race/ethnicity, parent education, and weight status, controlling for preschool.Results: Total PA was 14.5 and 15.2min/hr in the first and second samples, respectively. The prevalence of meeting the PA guideline was 41.6% and 50.2% in the first and second samples, respectively. In both samples, more males than females met the guideline (53.5% vs. 33.5% and 57.6% vs. 45.9%) in the first and second samples, respectively (p
