Physical activity and sedentary behavior among diverse Hispanic/Latino youth in the United States is not well documented. The aim of this study was to describe physical activity and sedentary behavior among a representative sample of Hispanic/Latino youth from four US communities using accelerometry and self-reported measures.
From 2012 to 2014, 1466 Hispanic/Latino youth ages 8 to 16 yr, children of participants in the Hispanic Community Health Study/Study of Latinos, enrolled in the SOL youth. Physical activity and sedentary behavior were assessed by interview. After this, youth wore an Actical accelerometer for 1 wk. All statistical analyses accounted for the complex survey design and used sampling weights.
The accelerometer wear time adjusted mean minutes per day was: 604.6, sedentary; 178.9, light; 25.4, moderate; and 10.2, vigorous. Generally, higher levels of moderate and vigorous activity occurred among males, Mexican backgrounds, and youth age 8 to 10 yr compared with older age groups. Higher levels of sedentary behavior occurred among youth age 15 to 16 yr compared with younger age groups. The most common activities (reported, ≥1 per month) were of lower intensity, including listening to music (91.9%), homework (87.0%), riding in car/bus (84.3%), and hanging out with friends (83.4%). Common active pursuits included travel by walking (74.6%), physical education class (71.7%), running (71.4%), and recess (71.3%).
Time, intensity, and type of physical activity and sedentary behavior varied among Hispanic/Latino youth. These findings can inform efforts to increase physical activity and reduce sedentary behavior among US Hispanic/Latino youth.
美国不同族裔的西班牙裔/拉丁裔青少年的身体活动和久坐行为尚未得到充分记录。本研究的目的是使用加速度计和自我报告的测量方法,描述来自美国四个社区的代表性西班牙裔/拉丁裔青少年的身体活动和久坐行为。
2012 年至 2014 年,共招募了 1466 名年龄在 8 至 16 岁的西班牙裔/拉丁裔青少年,他们是西班牙裔社区健康研究/拉丁裔研究参与者的子女,参加了 SOL 青少年项目。通过访谈评估身体活动和久坐行为。在此之后,青少年佩戴 Actical 加速度计 1 周。所有统计分析均考虑了复杂的调查设计并使用了抽样权重。
加速度计佩戴时间调整后的平均每日分钟数为:604.6 分钟,久坐;178.9 分钟,轻度;25.4 分钟,中度;10.2 分钟,剧烈。总体而言,与年龄较大的年龄组相比,男性、墨西哥裔背景和 8 至 10 岁的青少年中,中高强度活动水平较高。与年龄较小的年龄组相比,15 至 16 岁的青少年中久坐行为水平较高。最常见的活动(报告频率≥1 次/月)为低强度活动,包括听音乐(91.9%)、做作业(87.0%)、坐车/巴士(84.3%)和与朋友闲逛(83.4%)。常见的积极活动包括步行出行(74.6%)、体育课(71.7%)、跑步(71.4%)和课间休息(71.3%)。
西班牙裔/拉丁裔青少年的身体活动时间、强度和类型以及久坐行为存在差异。这些发现可以为在美国西班牙裔/拉丁裔青少年中增加身体活动和减少久坐行为的努力提供信息。
