This study compared the physical fitness level and weight status of children and adolescents in China and Japan. Children and adolescents aged 7-18 years were recruited (China: = 5660; Japan: = 5660). Physical fitness was assessed using seven core items-grip strength, 30-s sit-ups, standing long jump, sit-and-reach, 20-s repeated straddling, 20-m shuttle run test, and 50-m dash. A physical fitness index (PFI) was calculated by adding all items' -scores. We conducted comparisons of PFI and its distribution, each physical fitness item, and weight status for individuals from China and Japan across all ages. The PFI was lower in China than in Japan for all age groups, with an especially large difference at age 18 years for boys (a difference of 9.05) and girls (a difference of 9.10) ( < 0.001). The same result was seen for the seven items. The PFI distribution for children and adolescents was more disperse among those in Japan than among those in China. Obesity prevalence was 2.84 times higher in China than in Japan. An inverted U-shaped relationship was observed between physical fitness and nutritional status. Children and adolescents showed markedly lower physical fitness and higher obesity prevalence in China than in Japan.
本研究比较了中国和日本儿童和青少年的体质水平和体重状况。招募了 7-18 岁的儿童和青少年（中国：=5660；日本：=5660）。使用 7 项核心项目评估体质：握力、30 秒坐站、立定跳远、坐前伸、20 秒连续跨栏、20 米往返跑测试和 50 米短跑。通过将所有项目的得分相加计算出体质指数（PFI）。我们比较了中国和日本所有年龄段人群的 PFI 及其分布、各项体质项目和体重状况。所有年龄组的中国儿童和青少年的 PFI 均低于日本，男孩（相差 9.05）和女孩（相差 9.10）在 18 岁时差异尤为明显（<0.001）。7 项指标也呈现出相同的结果。日本儿童和青少年的 PFI 分布比中国更为分散。中国的肥胖患病率是日本的 2.84 倍。身体素质与营养状况之间存在着倒 U 型关系。中国儿童和青少年的身体素质明显低于日本，肥胖率也高于日本。
