体力活动对健康的益处是众所周知的，但生活在非洲和亚洲国家的儿童的体力活动数据有限。这项横断面研究的目的是评估和比较肯尼亚和日本儿童的体力活动和久坐行为模式，特别是每小时的变化。参与者包括298名9-12岁的小学生(122名肯尼亚人，176名日本人)。用加速度计测量体力活动和久坐行为。通过问卷调查来测量特定领域的体力活动、屏幕时间和使用主动交通工具上学的儿童的比例。采用双因素方差分析(国家x时间)来检验肯尼亚和日本儿童在活动模式上的差异。本研究的结果表明，与日本儿童相比，肯尼亚儿童在中等到剧烈的体力活动上花费的时间更多(p<；0.05)，其中工作日晚上(男孩和女孩)和周末下午(女孩)的差异最大。这表明，这些时期是区分肯尼亚和日本儿童体力活动水平的“关键时期”。然而，来自日本的儿童使用主动交通工具上学的比例更高，花在看电视和玩电脑游戏上的时间更少。结果表明，这两个国家都有成功和挑战，可以帮助制定有效的、针对具体国家的干预战略，以促进体育活动。
Health benefits of physical activity are well known, yet available physical activity data is limited from children living in African and Asian countries. The purpose of the cross-sectional study was to evaluate and compare physical activity and sedentary behavior patterns, particularly hourly variations, among children in Kenya and Japan. Participants included 298 primary school students (122 Kenyan, 176 Japanese) aged 9-12 years. Physical activity and sedentary behavior were measured with accelerometers. Domain-specific physical activity, screen time, and proportion of children using active transport to school were measured by questionnaire. A two-way ANOVA (countries x time) was used to examine the differences in the activity patterns between Kenyan and Japanese children. The results from the present study demonstrated that Kenyan children spent more time in moderate-to-vigorous physical activity compared to Japanese children (p< 0.05) with the greatest differences found for weekday evenings (for boys and girls) and weekend afternoons (for girls). This suggests that these were 'critical periods' to differentiate the physical activity levels between Kenyan and Japanese children. However, a higher proportion of the children from Japan used active transport to school and spent less time in television viewing and computer gaming. The results suggest that both countries have successes and challenges that can aid in developing effective and country-specific intervention strategies for promoting physical activity.
