There is little evidence on the associations between 24-h movement behaviours and health in children from low-income countries. We examined the associations of physical activity, sedentary behaviour, screen time and sleep with adiposity, motor skills and executive functions among 3- and 4-year-old children in Ethiopia.
Cross-sectional study conducted in Adama city and Lume Woreda, Oromia region, Ethiopia. We recruited children from kindergartens and rural Kebeles or villages. Children's time spent in physical activity, sedentary behaviour and sleep were measured using hip worn ActiGraph accelerometers. Children's screen time was parent-reported. Linear mixed models tested associations of 24-h movement behaviours with adiposity (BMI z-score), motor skills (NIH Toolbox) and executive functions (Early Years Toolbox). All models accounted for child sex, age and dietary diversity as fixed effects and clustering of children within kindergarten/villages as a random effect.
A total of 430 children participated (4.2 ± 0.6 years). Children who slept longer had lower adiposity (-0.12, 95% CI: -0.19, -0.06). Those who had higher levels of total physical activity (TPA) (0.06, 95% CI 0.01, 0.13) and moderate to vigorous-intensity physical activity (MVPA) (0.03, 95% CI 0.01, 0.06) had higher scores on handgrip strength. Children who spent more time in sedentary behaviour had lower handgrip strength (-0.08, 95% CI -0.16, -0.01). There were no significant associations with executive functions.
Strategies to improve adiposity and motor skills should focus on promoting healthy levels of 24-h movement behaviours, especially adequate sleep and time spent in physical activity in Ethiopian children.
关于低收入国家儿童24小时运动行为与健康之间的关联，证据很少。我们研究了埃塞俄比亚3至4岁儿童的身体活动、久坐行为、屏幕时间和睡眠与肥胖、运动技能和执行功能之间的关联。
在埃塞俄比亚奥罗米亚州阿达马市和卢梅县进行的横断面研究。我们从幼儿园和农村的凯贝勒或村庄招募儿童。使用佩戴在臀部的ActiGraph加速度计测量儿童在身体活动、久坐行为和睡眠中所花费的时间。儿童的屏幕时间由家长报告。线性混合模型测试了24小时运动行为与肥胖（BMI z评分）、运动技能（美国国立卫生研究院工具箱）和执行功能（早期儿童工具箱）之间的关联。所有模型将儿童性别、年龄和饮食多样性作为固定效应，并将幼儿园/村庄内儿童的聚类作为随机效应。
共有430名儿童参与（4.2±0.6岁）。睡眠时间较长的儿童肥胖程度较低（-0.12，95%CI：-0.19，-0.06）。那些总身体活动（TPA）水平较高（0.06，95%CI 0.01，0.13）和中度至剧烈强度身体活动（MVPA）水平较高（0.03，95%CI 0.01，0.06）的儿童握力得分较高。久坐行为时间较长的儿童握力较低（-0.08，95%CI -0.16，-0.01）。与执行功能没有显著关联。
改善肥胖和运动技能的策略应侧重于促进埃塞俄比亚儿童24小时运动行为达到健康水平，尤其是充足的睡眠和身体活动时间。
