目的了解对新疆维吾尔族单纯性肥胖中学生进行运动及饮食干预的效果,为有效制定广泛的干预方案提供支持。方法在乌鲁木齐市3所中学中选取单纯性肥胖中学生56名,并对肥胖学生进行体质测试,指标包括体质量指数(BMI)、皮脂厚度、血液指标、三围等,测试后随机均分为4个组别,分别进行干预,对干预测试后结果进行比较。结果干预后显示,有氧运动平衡膳食组体质量指数(BMI)为(27.83±2.53)kg/m2,对照组为(30.69±2.57)kg/m2,差异有统计学意义(t=2.97,P<0.01)。干预后有氧运动平衡膳食组与平衡膳食组在BMI、上臂围、腰围方面相比较,差异均有统计学意义(t值分别为2.52,2.40,3.31,P值均<0.05);有氧运动平衡膳食组与对照组及平衡膳食组在背部、上臂部、腹部皮褶厚度方面比较,差异均有统计学意义(F值分别为10.26,20.71,17.45,P值均<0.01);有氧运动平衡膳食组与对照组相比较除在三酰甘油含量方面相比较差异有统计学意义(t=2.56,P<0.05)外,其他血液指标(总胆固醇、高密度脂蛋白、低密度脂蛋白)差异均无统计学意义(P值均>0.05);有氧运动组三酰甘油含量干预前后净下降率62.0%,差异有统计学意义(t=2.34,P<0.05)。结论有氧运动平衡膳食能够有效降低维吾尔族肥胖中学生的肥胖程度。
Objective To understand the effects of exercise and dietary intervention on simple obese middle school students in Xinjiang Uygur and provide support for the effective formulation of a wide range of intervention programs. Methods 56 obese middle school students were enrolled in three middle schools in Urumqi. The body mass index (BMI), sebum thickness, blood parameters and measurements were also calculated for obese students. After the test, they were randomly divided into four groups Group, respectively, to intervene to compare the results of the intervention test. Results After intervention, the body mass index (BMI) was (27.83 ± 2.53) kg / m2 in the aerobic exercise balanced group and (30.69 ± 2.57) kg / m2 in the control group, the difference was statistically significant (t = 2.97, P <0.01). After intervention, there were significant differences in BMI, upper arm circumference and waist circumference between aerobic exercise balanced diet group and balanced diet group (t = 2.52,2.40,3.31, P <0.05). Aerobic exercise The difference between the balanced diet group and the control group and the balanced diet group was statistically significant (P <0.05), and the differences were statistically significant (F value were 10.26,20.71,17.45, P <0.01 respectively); aerobic exercise Compared with the control group, other blood parameters (total cholesterol, high density lipoprotein, low density lipoprotein) in the balanced diet group were significantly lower than those in the control group (t = 2.56, P <0.05) There was no significant difference between the two groups (P> 0.05). The net decrease rate of triglyceride content in aerobic exercise group was 62.0% before and after intervention, the difference was statistically significant (t = 2.34, P <0.05). Conclusion Aerobic exercise diet can effectively reduce the obesity among Uygur obese middle school students.
