To determine whether cardiovascular fitness (.)VO(2max) is associated with the metabolic syndrome and its individual features in overweight Latino youths.
A total of 163 overweight Latino boys and girls (body mass index (BMI) percentile = 97.0 +/- 3.1; age = 11.2 +/- 1.7 yr) with a family history of Type 2 diabetes participated in this investigation. The metabolic syndrome was defined as having three or more of the following risk factors: abdominal obesity, high blood pressure, low HDL-cholesterol, high triglycerides, and impaired glucose tolerance. (.)VO(2max) was determined by a progressive treadmill test to exhaustion, and body composition was assessed using dual energy x-ray absorptiometry.
(.)VO(2max) was not correlated with any individual risk factor of the metabolic syndrome after adjusting for gender, age, and body composition in partial analysis. Furthermore, ANCOVA revealed that children with zero, one, two, or three or more risk factors did not differ in regards to fitness levels.
(.)VO(2max) is not independently associated with the metabolic syndrome or any individual feature in overweight youths of Latino ethnicity after controlling for differences in confounding variables.
确定心血管健康水平（最大摄氧量）是否与超重拉丁裔青少年的代谢综合征及其个体特征相关。
共有163名有2型糖尿病家族史的超重拉丁裔男孩和女孩（体重指数百分位数=97.0±3.1；年龄=11.2±1.7岁）参与了本研究。代谢综合征被定义为具有以下三种或更多风险因素：腹部肥胖、高血压、低高密度脂蛋白胆固醇、高甘油三酯和糖耐量受损。通过递增式跑步机测试至力竭来测定最大摄氧量，并使用双能X线吸收法评估身体成分。
在部分分析中，在调整性别、年龄和身体成分后，最大摄氧量与代谢综合征的任何个体风险因素均无相关性。此外，协方差分析显示，具有零个、一个、两个或三个或更多风险因素的儿童在健康水平方面没有差异。
在控制混杂变量差异后，最大摄氧量与拉丁裔超重青少年的代谢综合征或任何个体特征无独立相关性。
