本研究旨在探讨青少年 24 小时运动行为（中度至剧烈体力活动、屏幕时间和睡眠时间）的聚类及其与心肺健康的关系。我们对来自巴西弗洛里亚诺波利斯的 561 名青少年（52.1% 是女孩；平均年龄 13.0 +/- 1.0 岁）进行了评估。 20米往返跑用于评估心肺健康，而问卷则用于测量24小时运动行为。进行潜在类别分析来识别 24 小时运动行为的聚类，同时应用线性贝叶斯混合效应回归模型来识别它们与心肺健康的关联。确定了两类：不健康（10.4%），其特征是每周进行中等到剧烈体力活动的时间少于 300 分钟、每天在屏幕前花费超过 4 小时、每天睡眠时间少于 8 小时；健康（89.6%），其特点是每周进行超过 420 分钟的中度至剧烈体力活动、每天在屏幕前花费的时间少于 2 小时、每天睡眠 8-10 小时。健康组青少年的心肺健康水平高于不健康组青少年。大多数青少年属于健康组，其心肺健康水平高于不健康组。这些结果表明，家庭和专业人士应努力为青少年创造更健康的生活方式，增加进行中度至剧烈体力活动的机会，减少屏幕时间，并支持健康睡眠，以提高心肺健康水平。已知信息：中心点，单独分析时，中度至剧烈体力活动、屏幕时间和睡眠持续时间分别与心肺健康呈正相关、负相关和不一致关系。中心点，人们对 24 小时运动行为的聚类及其与心肺健康的关系知之甚少。青少年的心肺健康水平。新增内容：中心点 青少年的 24 小时运动行为几乎分为相反的类别（健康和不健康类别）。中心点 健康类别的青少年比不健康类别的青少年具有更高的心肺健康水平。
This study aimed to examine the clustering of 24-h movement behaviors (moderate to vigorous physical activity, screen time, and sleep duration) and their association with cardiorespiratory fitness among adolescents. We evaluated 561 adolescents (52.1% girls; mean age, 13.0 +/- 1.0 years) from Florianopolis, Brazil. A 20-m shuttle run was used to assess cardiorespiratory fitness, while a questionnaire was used to measure 24-h movement behaviors. A latent class analysis was performed to identify the clustering of 24-h movement behaviors, while linear Bayesian mixed-effect regression models were applied to identify their association with cardiorespiratory fitness. Two classes were identified: unhealthy (10.4%), characterized as a high probability of practicing less than 300 min/week of moderate to vigorous physical activity, spending more than 4 h/day in front of screens, and sleeping less than 8 h/day; and healthy (89.6%), characterized by a high probability of practicing more than 420 min/week of moderate to vigorous physical activity, spending less than 2 h/day in front of screens, and sleeping 8-10 h/day. Adolescents in the healthy class had a higher cardiorespiratory fitness level than those in the unhealthy class. Most adolescents were grouped in the healthy class and had higher cardiorespiratory fitness levels than those in the unhealthy class. These results suggest that families and professionals should work toward creating healthier lifestyles for adolescents by increasing opportunities to practice moderate to vigorous physical activity, reduce screen time, and favor healthy sleep to increase their cardiorespiratory fitness levels.What is Known:center dot Moderate to vigorous physical activity, screen time, and sleep duration are positively, negatively, and inconsistently associated with cardiorespiratory fitness, respectively, when analyzed separately.center dot Little is known about the clustering of 24-h movement behaviors and how they are associated with cardiorespiratory fitness levels in adolescents.What is New:center dot The 24-h movement behaviors clustered into almost opposite classes among adolescents (healthy and unhealthy classes).center dot Adolescents in the healthy class had greater cardiorespiratory fitness levels than those in the unhealthy class.
