This study assessed the correlation between latitude and the cardiorespiratory fitness (CRF) of children and adolescents.
In 16 provinces and autonomous regions in China, 25,941 children and adolescents aged 10-18 were included. CRF was measured using the 20 m shuttle run test (20 m SRT) and estimated peak oxygen uptake (VO). One-way ANOVA and multiple regression analysis were used to explore the correlation between CRF and latitude in children and adolescents.
The VO values of the low (south), middle, and high (north) latitude groups for boys were 43.1, 43.1, and 40.7 mL/kg/min, respectively, and 40.0, 40.0, and 38.5 mL/kg/min for girls, respectively. After adjusting for confounding factors, the regression coefficients (β) between VO-Z and both latitude-Z and (latitude-Z) for boys were -0.151 and -0.043, respectively. For girls, they were -0.142 and -0.020, respectively. The Partial correlation coefficient () for latitude-Z and (latitude-Z) were -0.14 and -0.04 for boys, and -0.13 and -0.02 for girls, respectively.
The CRF among children and adolescents in high latitude regions is significantly lower than that in middle and low latitude region, and it generally shows a "parabolic" trend between Latitude-Z and VO-Z.
本研究评估了纬度与儿童青少年心肺适能（CRF）之间的相关性。
纳入中国16个省和自治区的25941名10 - 18岁儿童青少年。采用20米往返跑测试（20m SRT）测量CRF，并估算峰值摄氧量（VO）。采用单因素方差分析和多元回归分析探讨儿童青少年CRF与纬度之间的相关性。
男孩低（南部）、中、高（北部）纬度组的VO值分别为43.1、43.1和40.7 mL/kg/min，女孩分别为40.0、40.0和38.5 mL/kg/min。调整混杂因素后，男孩VO-Z与纬度-Z和（纬度-Z）之间的回归系数（β）分别为-0.151和-0.043。女孩的回归系数分别为-0.142和-0.020。男孩纬度-Z和（纬度-Z）的偏相关系数分别为-0.14和-0.04，女孩分别为-0.13和-0.02。
高纬度地区儿童青少年的CRF显著低于中低纬度地区儿童青少年，且纬度-Z与VO-Z之间总体呈“抛物线”趋势。
