Strategic health interventions must be guided by effective surveillance systems that monitor population trends and patterns, therefore we aimed to provide youth's (6-14 years) national prevalence estimates of physical activity (PA), active outdoor play (AOP), sedentary behaviur (SB), and structured PA (SPA).
Measures of moderate-to-vigorous PA, SB, AOP, and SPA, were obtained for 719 participants in 2 groups (6-9 and 10-14 years) using diaries and questionnaires. National estimates were calculated, by sex, region, and parental education.
While 54% (95%CI: 47.4-61.3) of youth meet PA recommendations, the prevalence is lower for the older group ( .034). Similarly, AOP decreases with age both on weekends, from 94.3% (95%CI: 90.8-97.8) to 68.7% (95%CI: 62.2-75.1), and on weekdays from 84% (95%CI: 76.5-91.5) to 64.8% (95%CI: 59-70.6). Watching TV for ≥2 h/day is extremely high on weekends [71.3% (95%CI: 65.4-77.2)] and more prevalent in boys than girls on weekdays ( = .043). Higher parental education significantly increased SPA and active time. Time in SB was greater in boys [7.26 h (95%CI: 6.87-7.65)] than girls [6.48 h (95%CI: 6.09-6.87)] and increased with age ( < .001).
Almost half of the youth failed to achieve PA guidelines, whereas 71% exceeded recommended TV time on weekends, suggesting the urgency of intervention measures.
战略卫生干预措施必须以监测人群趋势和模式的有效监测系统为指导,因此我们旨在提供青少年(6 - 14岁)身体活动(PA)、户外积极玩耍(AOP)、久坐行为(SB)和有组织的身体活动(SPA)的全国患病率估计值。
使用日记和问卷,对两组(6 - 9岁和10 - 14岁)的719名参与者进行了中度至剧烈身体活动、久坐行为、户外积极玩耍和有组织的身体活动的测量。按性别、地区和父母教育程度计算全国估计值。
虽然54%(95%CI:47.4 - 61.3)的青少年达到了身体活动建议标准,但年龄较大的组患病率较低(P = 0.034)。同样,户外积极玩耍在周末和工作日均随年龄增长而减少,周末从94.3%(95%CI:90.8 - 97.8)降至68.7%(95%CI:62.2 - 75.1),工作日从84%(95%CI:76.5 - 91.5)降至64.8%(95%CI:59 - 70.6)。每天看电视≥2小时在周末极高[71.3%(95%CI:65.4 - 77.2)],且在工作日男孩比女孩更普遍(P = 0.043)。父母教育程度较高显著增加了有组织的身体活动和活动时间。男孩的久坐时间[7.26小时(95%CI:6.87 - 7.65)]比女孩[6.48小时(95%CI:6.09 - 6.87)]更长,且随年龄增长而增加(P < 0.001)。
几乎一半的青少年未达到身体活动指南标准,而71%的青少年在周末看电视时间超过建议时长,这表明采取干预措施的紧迫性。
