To estimate the prevalence of metabolic syndrome and insulin resistance in a cohort of Division 1 collegiate football players.
Ninety football players were evaluated in a cross-sectional study to estimate the prevalence of metabolic syndrome, insulin resistance, and associated risk factors. Obesity was defined as a body fat >or=25% determined by BOD POD measurements. The National Cholesterol Education Program Adult Treatment Panel III criteria were used to estimate prevalence of metabolic syndrome. Quantitative insulin sensitivity check index calculations were performed to estimate prevalence of insulin resistance. Linear regression techniques were used to determine association between body fat percentage and other measured continuous parameters. Fisher exact test was used to determine association between nominal variables, and one-way ANOVA compared the three groups defined by position.
Summary measures showed a small prevalence of abnormal individual measurements. There was an association between body fat percentage and most evaluated parameters (P < 0.05). The prevalence of obesity, insulin resistance, and metabolic syndrome was 21%, 21%, and 9%, respectively. Obesity is closely associated with metabolic syndrome (P < 0.0001) and insulin resistance (P < 0.0001) in this population. All subjects with metabolic syndrome were obese, and the odds for insulin resistance in the obese group are 10.6 times the odds for the nonobese group. Linemen (n = 29) had 19 of the 19 obese subjects, 13 of the 19 subjects with insulin resistance, and all subjects with metabolic syndrome.
There is a strong association between obesity and both metabolic syndrome and insulin resistance in Division 1 collegiate football players. Linemen are at significant risk for metabolic syndrome and insulin resistance compared with other positions. This may be predictive of future health problems in Division 1 collegiate football players, especially linemen.
评估一级大学橄榄球运动员队列中代谢综合征和胰岛素抵抗的患病率。
在一项横断面研究中，对 90 名橄榄球运动员进行评估，以评估代谢综合征、胰岛素抵抗和相关危险因素的患病率。肥胖定义为通过 BOD POD 测量确定的体脂>或=25%。使用国家胆固醇教育计划成人治疗小组 III 标准来估计代谢综合征的患病率。进行定量胰岛素敏感性检查指数计算以估计胰岛素抵抗的患病率。线性回归技术用于确定体脂百分比与其他测量的连续参数之间的关联。Fisher 确切检验用于确定名义变量之间的关联，单因素方差分析比较按位置定义的三组。
汇总测量结果显示异常个体测量的患病率较低。体脂百分比与大多数评估参数之间存在关联（P < 0.05）。肥胖、胰岛素抵抗和代谢综合征的患病率分别为 21%、21%和 9%。肥胖与代谢综合征（P < 0.0001）和胰岛素抵抗（P < 0.0001）密切相关。该人群中所有患有代谢综合征的患者均肥胖，肥胖组发生胰岛素抵抗的几率是非肥胖组的 10.6 倍。线卫（n = 29）有 19 名肥胖患者，19 名胰岛素抵抗患者，以及所有代谢综合征患者。
一级大学橄榄球运动员中肥胖与代谢综合征和胰岛素抵抗之间存在很强的关联。与其他位置相比，线卫具有代谢综合征和胰岛素抵抗的显著风险。这可能预示着一级大学橄榄球运动员未来的健康问题，尤其是线卫。
