Adolescents with disabilities (A-With-D) have shown to be less physically active and more obese compared to adolescents without disabilities (A-Without-D); however, little is known in regards to the impact of physical activity (PA) and body mass index (BMI) on metabolic syndrome (MetS) among A-with-D.
The purpose of this study was to compare the prevalence of MetS, PA levels and BMI percentile between A-With-D and A-Without-D, and to examine the influence of PA and BMI on MetS among A-With-D.
Data from the National Health and Nutrition Examination Survey 1999-2010 was used in this study. Inclusion criteria for the study consisted of those who indicated, in the survey, that they had received special education or early intervention service (n = 278). PA level was assessed subjectively by asking the amount of leisure time PA. BMI percentile was obtained using BMI growth charts by age and sex. The continuous MetS (cMetS) score was computed using age and sex standardized residual for mean arterial blood pressure, triglyceride, glucose, waist circumference, and high-density lipoprotein cholesterol.
A-With-D were more likely to be obese and less likely to be engaged in PA compared to A-Without-D. A-With-D were less favorable to MetS with significantly higher cMetS scores than A-Without-D. Lower levels of PA and higher percentile of BMI were significantly associated with higher levels of cMetS scores among A-With-D.
This study provided empirical evidence for the importance of promoting a healthy lifestyle (i.e., increasing the level of PA and decreasing the BMI percentile) among A-With-D in order to reduce the risk of MetS.
与无残疾青少年相比，残疾青少年（A-With-D）的身体活动水平较低，肥胖率较高；然而，对于 A-With-D 群体中身体活动（PA）和体重指数（BMI）对代谢综合征（MetS）的影响知之甚少。
本研究旨在比较 A-With-D 和 A-Without-D 之间 MetS 的患病率、PA 水平和 BMI 百分位数，并探讨 PA 和 BMI 对 A-With-D 中 MetS 的影响。
本研究使用了 1999-2010 年全国健康和营养调查的数据。研究的纳入标准包括在调查中表示接受过特殊教育或早期干预服务的人（n=278）。PA 水平通过询问闲暇时间 PA 的量来进行主观评估。BMI 百分位数是通过 BMI 生长图表根据年龄和性别获得的。连续 MetS（cMetS）评分是使用年龄和性别标准化的平均动脉血压、甘油三酯、葡萄糖、腰围和高密度脂蛋白胆固醇的残差计算得出的。
与 A-Without-D 相比，A-With-D 更有可能肥胖，更不可能参与 PA。A-With-D 的 MetS 更不理想，cMetS 评分明显高于 A-Without-D。PA 水平较低和 BMI 百分位数较高与 A-With-D 中 cMetS 评分较高显著相关。
本研究为在 A-With-D 中促进健康生活方式（即增加 PA 水平和降低 BMI 百分位数）以降低 MetS 风险的重要性提供了经验证据。
