背景:来自全球不同样本的关于3至4岁儿童每天总体力活动(TPA)达到180分钟全球指南的患病率和相关性的证据有限。
方法:横断面研究涉及来自17个中高收入国家的797名3至4岁儿童(49.2%的女孩),他们参加了SUNRISE早期运动行为国际研究的试点阶段1和2。使用大腿磨损的activPAL加速度计测量每日步数。儿童佩戴加速度计至少24小时。根据每天达到≥11,500步,将儿童归类为符合TPA指南。进行了描述性分析,以描述满足总样本和每个社会人口统计学变量的TPA指南的比例。并计算95%CI。多变量逻辑回归用于确定符合TPA指南的社会人口统计学相关性。
结果:平均每日步数为每天10,295步(SD=4084)。大约三分之一的样本(30.9%,95%CI,27.6-34.2)符合TPA指南。女孩(调整后的OR[aOR]=0.70,95%CI,0.51-0.96)和4岁儿童(aOR=0.50,95%CI,0.34-0.75)的比例明显较低,农村居民(aOR=1.78,95%CI,1.27-2.49)和中低收入国家(aOR=1.35,95%CI,0.89-2.04)的比例较高。
结论:研究结果表明,少数儿童可能符合全球TPA指南,不符合指南的风险因社会人口统计学指标而异。这些发现表明,需要在全球范围内对幼儿进行更多的TPA监测,可能,改善儿童健康和发展的干预措施。
BACKGROUND: There is limited evidence from globally diverse samples on the prevalence and correlates of meeting the global guideline of 180 minutes per day of total physical activity (TPA) among 3- to 4-year-olds.
METHODS: Cross-sectional study involving 797 (49.2% girls) 3- to 4-year-olds from 17 middle- and high-income countries who participated in the pilot phases 1 and 2 of the SUNRISE International Study of Movement Behaviours in the Early Years. Daily step count was measured using thigh-worn activPAL accelerometers. Children wore the accelerometers for at least one 24-hour period. Children were categorized as meeting the TPA guideline based on achieving ≥11,500 steps per day. Descriptive analyses were conducted to describe the proportion of meeting the TPA guideline for the overall sample and each of the sociodemographic variables, and 95% CIs were calculated. Multivariable logistic regression was used to determine the sociodemographic correlates of meeting the TPA guideline.
RESULTS: Mean daily step count was 10,295 steps per day (SD = 4084). Approximately one-third of the sample (30.9%, 95% CI, 27.6-34.2) met the TPA guideline. The proportion meeting the guideline was significantly lower among girls (adjusted OR [aOR] = 0.70, 95% CI, 0.51-0.96) and 4-year-olds (aOR = 0.50, 95% CI, 0.34-0.75) and higher among rural residents (aOR = 1.78, 95% CI, 1.27-2.49) and those from lower middle-income countries (aOR = 1.35, 95% CI, 0.89-2.04).
CONCLUSIONS: The findings suggest that a minority of children might meet the TPA guideline globally, and the risk of not meeting the guideline differed by sociodemographic indicators. These findings suggest the need for more surveillance of TPA in young children globally and, possibly, interventions to improve childhood health and development.
