目的探讨以有氧运动为基础,采取一系列综合措施对单纯性肥胖儿童脂肪肝的影响。方法 2016年1月至12月选择68名单纯性肥胖脂肪肝儿童,随机分成对照组(33例)和干预组(35例),干预组给予饮食、运动、健康教育干预,对照组无任何干预措施,12个月后分别测定两组体重、腰围、体质指数(BMI)、总胆固醇(TC)、甘油三酯(TG)、丙氨酸氨基转移酶(ALT)、天门冬酸氨基转移酶(AST),B超对两组脂肪肝程度分级。结果干预12个月后,干预组体重、腰围、BMI、TC、TG、AST、ALT均低于对照组,差异有统计学意义(t=3.39、2.82、6.6773、14.45、3.03、5.88、5.69,P均<0.05);干预组轻、中度脂肪肝比例均低于对照组,差异有统计学意义(χ~2=9.90、4.09,P均<0.05),重度脂肪肝比例均低于对照组,但差异无统计学意义(χ~2=3.32,P>0.05),干预组脂肪肝程度轻于对照组,差异有统计学意义(χ~2=30.67,P<0.05)。结论基于有氧运动的综合干预(饮食调整、行为矫正、健康教育)对单纯性肥胖儿童脂肪肝改善效果明显。
Objective To investigate the effect of taking a series of comprehensive measures on the fatty liver of simple obesity children based on aerobic exercise. Methods A total of 68 children with simple fatty liver from January 2016 to December were randomly divided into control group (n = 33) and intervention group (n = 35). The intervention group was given diet, exercise and health education intervention without intervention After 12 months, the body weight, waist circumference, body mass index (BMI), total cholesterol (TC), triglyceride (TG), alanine aminotransferase (ALT), aspartate aminotransferase AST), B-grade on the two groups of fatty liver grading. Results After intervention for 12 months, the body weight, waist circumference, BMI, TC, TG, AST and ALT in the intervention group were all lower than those in the control group (t = 3.39,2.82,6.6773,14.45,3.03,5.88,5.69, P <0.05). The proportion of mild and moderate fatty liver in the intervention group was lower than that in the control group (χ ~ 2 = 9.90, 4.09, P <0.05), and the proportion of severe fatty liver was lower than that in the control group , But the difference was not statistically significant (χ ~ 2 = 3.32, P> 0.05). The degree of fatty liver in the intervention group was lighter than that in the control group (χ ~ 2 = 30.67, P <0.05). Conclusion The comprehensive intervention based on aerobic exercise (diet adjustment, behavior correction, health education) has obvious effect on improving fatty liver in simple obesity children.
