The purpose of this study was twofold: first, to compare the central adiposity (CA), cardiovascular fitness (CF), and physical activity (PA) in children with different weight status, and second, to determine the associations between moderate to vigorous physical activity (MVPA) and measures of adiposity [CA and body mass index (BMI)] and CF. A sample of 244 children (boys = 120 and girls = 124), 9.7-10.8 years of age (10.3 ± 0.3 years), was measured for stature, body mass, waist circumferences, and 20-m multi-stage fitness test. PA was recorded with ankle mounted accelerometer. BMI groups were used to classify children as underweight (UW), normal weight (NW), and overweight (OW). The prevalence of being OW was 21.7 and 25% in boys and girls, respectively. Only 5.3% of the participants were found to accumulate recommended amount (≥60 min/day) of MVPA. Boys were significantly outperformed girls in terms of CF. Moreover, they were significantly more engaged in moderate and vigorous physical activities than girls. Regardless of gender, results indicated that OW children had significantly higher values in all anthropometric parameters and lower level of CF than their UW and NW counterparts. In girls, OW children were found to accrue less time engaging in MVPA than the children in UW and NW groups. In boys, OW children were found to accrue less time engaging in vigorous activities than UW and NW children. Results also showed that there were no significant differences between UW and NW girls and boys in respect to CF. Besides, UW girls were found to accrue more time engaging in MVPA than NW girls. MVPA was found to be significantly and negatively correlated with BMI and waist circumference and significantly and positively correlated with CF in both boys and girls. These discrepancies and associations highlight the considerable influences of MVPA on weight status and CF in children.
第一，比较不同体重状况儿童的中心性肥胖（CA）、心血管适能（CF）和身体活动（PA）；第二，确定中度至剧烈身体活动（MVPA）与肥胖指标[CA和体重指数（BMI）]及CF之间的关联。对244名9.7至10.8岁（10.3±0.3岁）的儿童（男孩120名，女孩124名）进行了身高、体重、腰围和20米多级适能测试。使用脚踝佩戴的加速度计记录PA。根据BMI分组将儿童分为体重过轻（UW）、正常体重（NW）和超重（OW）。男孩和女孩中超重的患病率分别为21.7%和25%。仅5.3%的参与者达到了推荐的MVPA量（≥60分钟/天）。在CF方面，男孩的表现明显优于女孩。此外，他们参与中度和剧烈身体活动的程度明显高于女孩。无论性别如何，结果表明，OW儿童在所有人体测量参数上的值均显著高于其UW和NW同龄人，而CF水平则较低。在女孩中，发现OW儿童参与MVPA的时间比UW和NW组的儿童少。在男孩中，发现OW儿童参与剧烈活动的时间比UW和NW儿童少。结果还表明，UW和NW的女孩和男孩在CF方面没有显著差异。此外，发现UW女孩参与MVPA的时间比NW女孩多。在男孩和女孩中，MVPA均与BMI和腰围呈显著负相关，与CF呈显著正相关。这些差异和关联凸显了MVPA对儿童体重状况和CF的重大影响。
