背景/目的预防肥胖的一个要素是增加总体力活动能量消耗。然而，这种方法并不包括平衡的各种运动行为的身体活动，久坐不动的行为和睡眠跨域的一天。我们的目的是确定时间使用概况超过工作和休闲，被称为“运动行为概况”，并调查他们与肥胖的关联。受试者/方法807名工人完成（a）大腿加速度和日记，以确定他们的24小时组成的行为（久坐和站立，轻体力活动和中度到剧烈的体力活动，在工作和休闲，在床上的时间）和（B）肥胖测量。运动行为的配置文件，确定使用潜在的配置文件分析的等距对数比的24小时组成，并根据动物的运动行为特征标记。应用线性模型来确定轮廓和肥胖之间的关联。结果共识别出4种基因型，分别为“黑猩猩”（n = 226）、“狮子”（n = 179）、“蚂蚁”（n = 244）和“考拉”（n = 158）。“黑猩猩”的工作时间在行为之间均匀分布，而他们的休闲时间主要是活跃的。与黑猩猩相比，“狮子”在工作时更活跃，在休闲时久坐不动，在床上花费的时间更多;“蚂蚁”在工作和休闲时更活跃;“考拉”在工作和休闲时更久坐不动，在床上花费的时间相似。以“黑猩猩”为参照，“狮子”的肥胖指标最差：+2.0（95%置信区间[CI] 0.6，3.4）%体脂，+4.3 cm（1.4，7.3）腰围和+1.0（2.0，0.0）体重指数（BMI），其次是“考拉”+2.0（0.4，3.7）%体脂，+3.1 cm（0.1，6.0）腰围，+0.8（-0.30，1.94）BMI。在“黑猩猩”和“蚂蚁”之间没有发现显著差异。结论：工作和休闲时间使用构成中的运动行为特征与肥胖相关。在工作和休闲运动行为之间取得适当的平衡应作为一种潜在的肥胖预防策略进行进一步研究。
Background/objectives An element of obesity prevention is increasing total physical activity energy expenditure. However, this approach does not incorporate the balance of various movement behaviors-physical activity, sedentary behaviors and sleep-across domains of the day. We aimed to identify time-use profiles over work and leisure, termed 'movement behavior profiles' and to investigate their association with obesity. Subjects/methods Eight-hundred-and-seven workers completed (a) thigh accelerometry and diaries to determine their 24-h composition of behaviors (sedentary and standing, light physical activity and moderate-to-vigorous physical activity at work and leisure, and time in bed) and (b) obesity measurements. Movement behavior profiles were determined using latent profile analyses of isometric log-ratios of the 24-h composition, and labeled according to animal movement behavior traits. Linear models were applied to determine the association between profiles and obesity. Results Four profiles were identified, labeled as "Chimpanzees" (n = 226), "Lions" (n = 179), "Ants" (n = 244), and "Koalas" (n = 158). "Chimpanzees" work time was evenly distributed between behaviors while their leisure time was predominantly active. Compared to Chimpanzees, "Lions" were more active at work and sedentary during leisure and spent more time in bed; "Ants" were more active at work and during leisure; "Koalas" were more sedentary at work and leisure and spent similar time in bed. With "Chimpanzees" as reference, "Lions" had least favorable obesity indicators: +2.0 (95% confidence interval [CI] 0.6, 3.4) %body fat, +4.3 cm (1.4, 7.3) waist circumference and +1.0 (2.0, 0.0) Body Mass Index (BMI), followed by "Koalas" +2.0 (0.4, 3.7) %body fat, +3.1 cm (0.1, 6.0) waist circumference, and +0.8 (-0.30, 1.94) BMI. No significant differences were found between "Chimpanzees" and "Ants". Conclusions Movement behavior profiles across work and leisure time-use compositions are associated with obesity. Achieving adequate balance between work and leisure movement behaviors should be further investigated as a potential obesity prevention strategy.
