The objective was to determine the prevalence of overweight and obesity, and its association with physical activity and fitness among boys attending a private school in Bogotá, Colombia. 655 boys between 7 and 18 years self-reported their physical activity habits and underwent anthropometric (weight, height, fat percentage by bioelectrical impedance), and physical fitness measurements (PACER, sit and reach, curl-ups, push-ups and hand dynamometry). The association between weight status and physical activity and fitness were assessed by logistic regression models. The outcome was that 38% of the boys were overweight according to the BMI of the Colombian population (WHO criteria), 17,7% according to international BMI cut-offs and 16.9% showed values of % fat over 25 (Fitnessgram criteria). A relation was found between being overweight and having poor performance in the aerobic fitness test (adjusted OR: 3.7, IC 95%: 1.6-8.3) and reported not walking or riding a bicycle for at least 30 minutes, 5 times a week (OR adjusted 3.6, IC 95%: 1-13.0). These results did not change when different criteria to define overweight was applied. The best level of agreement for overweight classification was found between fat per centage and the international BMI cut-offs (kappa=0.616, p<0.001). Overweight was not associated to TV watching time, video games or use of Internet. The final conclusion was that the prevalence of overweight was high in this population of school-aged boys. There was a significant relationship between poor physical fitness, low levels of physical activity, and overweight. It is important to encourage and monitor children's levels of physical activity as well as the results of fitness test for the prevention of overweight and related cardio-metabolic complications.
目的是确定哥伦比亚波哥大一所私立学校男生中超重和肥胖的患病率，以及其与身体活动和健康状况的关联。655名7至18岁的男生自行报告了他们的身体活动习惯，并接受了人体测量（体重、身高、通过生物电阻抗测量的脂肪百分比）和身体素质测量（20米往返跑、坐位体前屈、仰卧起坐、俯卧撑和握力测量）。通过逻辑回归模型评估体重状况与身体活动和健康状况之间的关联。结果显示，根据哥伦比亚人群的BMI（世界卫生组织标准），38%的男生超重；根据国际BMI临界值，超重比例为17.7%；16.9%的男生脂肪百分比超过25%（青少年健身测试标准）。研究发现，超重与有氧适能测试成绩不佳（调整后的比值比：3.7，95%置信区间：1.6 - 8.3）以及报告每周至少5次没有步行或骑自行车30分钟以上有关（调整后的比值比3.6，95%置信区间：1 - 13.0）。当应用不同的超重定义标准时，这些结果并未改变。在脂肪百分比和国际BMI临界值之间发现了超重分类的最佳一致性水平（kappa = 0.616，p < 0.001）。超重与看电视时间、玩电子游戏或使用互联网无关。最终结论是该学龄男生群体中超重患病率较高。身体素质差、身体活动水平低与超重之间存在显著关系。鼓励并监测儿童的身体活动水平以及健身测试结果对于预防超重和相关的心血管代谢并发症很重要。
