Waist-to-height ratio (WHtR) is considered an important summary indicator for assessing the health of children and adolescents. However, there are fewer studies addressing the association between WHtR and cardiorespiratory fitness (CRF). Deriving an optimal WHtR would play an important role in promoting CRF in children and adolescents. Our aim was to analyze the association between WHtR and CRF and determine the optimal value of WHtR.
In this study, 37,081 (19,125 boys, 51.6%) children and adolescents aged 7-18 years in five regions of China were tested for WHtR and 20-m shuttle run test (20 m SRT). One-way ANOVA was used to compare maximum oxygen uptake (VO) among children and adolescents with different WHtRs and effect sizes were used to analyze differences between groups. Curvilinear regression was used to analyse the curvilinear relationship that exists between WHtR and VO.
In Chinese children and adolescents, the WHtR of boys was higher than that of girls by 0.01, and the difference was statistically significant (P < 0.001). Overall, in the age groups of 7-9, 10-12, 13-15, and 16-18 years old, the differences in VO comparisons between different WHtR groups were statistically significant (P < 0.001). In Chinese children and adolescents in the age groups of 7-9, 10-12, 13-15, and 16-18 years old, VO levels were highest when the WHtR was 0.34, 0.32, 0.39, and 0.41, respectively.
There is a curvilinear association between WHtR and CRF in Chinese children and adolescents. Both lower and higher WHtR led to a decrease in VO in children and adolescents.
腰高比（WHtR）被认为是评估儿童和青少年健康状况的一项重要综合指标。然而，针对WHtR与心肺适能（CRF）之间关联的研究较少。得出最佳的WHtR对于促进儿童和青少年的CRF具有重要作用。我们的目的是分析WHtR与CRF之间的关联，并确定WHtR的最佳值。
在本研究中，对中国五个地区37,081名年龄在7至18岁的儿童和青少年（19,125名男孩，占51.6%）进行了WHtR和20米往返跑测试（20 m SRT）。采用单因素方差分析比较不同WHtR的儿童和青少年的最大摄氧量（VO），并使用效应量分析组间差异。采用曲线回归分析WHtR与VO之间存在的曲线关系。
在中国儿童和青少年中，男孩的WHtR比女孩高0.01，差异具有统计学意义（P < 0.001）。总体而言，在7至9岁、10至12岁、13至15岁和16至18岁年龄组中，不同WHtR组之间的VO比较差异具有统计学意义（P < 0.001）。在中国7至9岁、10至12岁、13至15岁和16至18岁年龄组的儿童和青少年中，当WHtR分别为0.34、0.32、0.39和0.41时，VO水平最高。
在中国儿童和青少年中，WHtR与CRF之间存在曲线关联。WHtR过低或过高均会导致儿童和青少年的VO下降。
