. The main purpose of this study was to explore the body-mass index and waist circumference associated with physical fitness by gender. In this cross-sectional study, we included 1036 adolescents (55.4% girls) from eight randomly selected secondary schools within the city of Zagreb (Croatia). Body-mass index and waist circumference were objectively measured. Physical fitness included three tests: (1) 1 min sit-ups, (2) standing long jump and (3) a sit-and-reach test. Associations were calculated using linear regression models. Boys had higher body-mass index and waist circumference values, compared to girls ( < 0.001). They also performed better in 1 min sit-ups and the standing long jump tests ( < 0.001), while girls obtained higher values in the sit-and-reach test ( < 0.001). In boys, body-mass index and waist circumference were associated with 1 min sit-ups and the standing long jump. In girls, waist circumference was also associated with 1 min sit-ups and the standing long jump, while body-mass index was only associated with this standing long jump. Our study shows that anthropometric indices have non-linear associations with physical fitness tests in a large sample of Croatian adolescents. Screening for thinness and obesity to predict the level of physical fitness should be of a great interest.
. 本研究的主要目的是探讨按性别划分的与身体健康相关的体质指数和腰围。在这项横断面研究中，我们纳入了来自克罗地亚萨格勒布市 8 所随机抽取的中学的 1036 名青少年（55.4%为女孩）。对体质指数和腰围进行了客观测量。身体素质包括三项测试：（1）1 分钟仰卧起坐，（2）立定跳远，（3）坐前伸测试。使用线性回归模型计算了相关性。与女孩相比，男孩的体质指数和腰围更高（<0.001）。他们在 1 分钟仰卧起坐和立定跳远测试中的表现也更好（<0.001），而女孩在坐前伸测试中的得分更高（<0.001）。在男孩中，体质指数和腰围与 1 分钟仰卧起坐和立定跳远有关。在女孩中，腰围也与 1 分钟仰卧起坐和立定跳远有关，而体质指数仅与这个立定跳远有关。我们的研究表明，在一个很大的克罗地亚青少年样本中，人体测量指数与身体素质测试之间存在非线性关系。筛查消瘦和肥胖以预测身体素质水平应该是非常重要的。
