背景：由于缺乏对年轻人口身体行为的监测，拉丁美洲和加勒比国家的人口比例历来偏低。因此，这项研究的目的是描述和比较洛杉矶26个国家的青少年的总体体力活动(PA)、积极的上学和放学交通工具(如步行或骑自行车)、体育活动(PE)和久坐行为(SB)。结果：034名青少年提供了完整的数据(年龄范围：11~18岁；47.7%为男性)。在拉丁美洲和加勒比国家，只有大约15%的青少年进行体育活动(每天至少60分钟的中等到剧烈的PA)，大多数国家显示出性别差异。总体而言，41.9%的人报告每周至少有3天活跃于接送学生上下学。在12个国家中，至少50%的青少年报告每天课外坐3小时，三分之一的青少年每周参加3天或更多的体育课。结论：这项研究给拉美地区带来了挑战，因为缺乏体育活动和SB在所有国家都很普遍。性别不平等在大多数国家都表现出来，男孩报告的行为更活跃。迫切需要采取区域和国家行动，执行扭转这一局面的政策。
Background: Latin America and the Caribbean (LAC) countries, have been historically under-represented due to the lack of surveillance of physical behaviours in young populations. Therefore, the aim of this study was to describe and compare overall physical activity (PA), active transportation to and from school (i.e. walking or cycling), physical education (PE) participation, and sedentary behaviour (SB) in adolescents from 26 countries in LAC.Methods: Data were collected in the Global School-based Student Health Survey (2007-13). Prevalences for each physical behaviour were compared by sex across the region.Results: In total, 64 034 adolescents provided complete data (age range: 11 to 18 years; 47.7% male). Only about 15% of adolescents in LAC countries were physically active (at least 60 min/day of moderate-to-vigorous PA) with most countries showing sex disparities. Overall, 41.9% reported being active for transportation to and from school at least 3 days per week. In 12 countries, at least 50% of the adolescents reported sitting >= 3 h per day outside school, and a third of adolescents reported participation in PE classes on 3 days or more per week.Conclusions: The study sets a challenge for the LAC region, as physical inactivity and SB are highly prevalent across all countries. Gender inequity was shown in most countries, with boys reporting more active behaviours. Regional and national actions for implementing policies to revert this situation are urgent.
