Excess sedentary behaviour (SB) and insufficient physical activity have been identified as risk factors for cardiometabolic diseases in adolescents, and some factors may affect how much time they spend on these activities. This study sought to compare the SB and PA patterns as well as compliance with PA recommendations by sex, geographical location, and time of the week in Mexican adolescents. In a cross-sectional design, we objectively assessed SB and PA in 106 adolescents (15 to 18 y) through waist-worn accelerometers for one week. The time spent in SB and in PA at different intensities was compared by sex, geographical location and time of the week with two-way and three-way repeated measures MANOVAs, while the compliance with physical activity recommendations (i.e., ≥60 min/day) was compared using chi-squared and McNemar tests. : Male participants spent more time in moderate, vigorous, and moderate to vigorous PA than females both during the whole week and on weekdays (all < 0.05). There was no significant difference in SB nor PA by geographical location (i.e., metropolitan vs. non-metropolitan areas). Moreover, all participants spent more time on moderate, vigorous, and moderate to vigorous PA on weekdays than on weekends ( < 0.05). Compliance with international PA recommendations also showed a sex difference (males > females) and change between weekdays and weekends with no difference by geographical location. While geographical location does not seem to be a relevant factor, sex and time of the week appear to influence the SB and PA patterns in Mexican adolescents.
久坐行为过多和体育活动不足已被确定为青少年心血管代谢疾病的风险因素，一些因素可能会影响他们在这些活动上花费的时间。本研究旨在比较墨西哥青少年按性别、地理位置和一周中的时间划分的久坐行为和体育活动模式以及对体育活动建议的遵守情况。在一项横断面设计中，我们通过佩戴在腰部的加速度计对106名青少年（15至18岁）的久坐行为和体育活动进行了为期一周的客观评估。通过双向和三向重复测量多元方差分析，比较了按性别、地理位置和一周中的时间划分的久坐行为和不同强度体育活动所花费的时间，同时使用卡方检验和麦克尼马尔检验比较了对体育活动建议（即每天≥60分钟）的遵守情况。男性参与者在整个星期和工作日花费在中等强度、高强度以及中等至高强度体育活动上的时间都比女性多（所有P<0.05）。按地理位置（即大城市与非大城市地区）划分，久坐行为和体育活动没有显著差异。此外，所有参与者在工作日花费在中等强度、高强度以及中等至高强度体育活动上的时间比周末多（P<0.05）。对国际体育活动建议的遵守情况也存在性别差异（男性>女性），并且在工作日和周末之间有所变化，按地理位置没有差异。虽然地理位置似乎不是一个相关因素，但性别和一周中的时间似乎会影响墨西哥青少年的久坐行为和体育活动模式。
