目的分析牛奶饮用频率与儿童肥胖及代谢指标异常率的关系,为制定相应疾病的干预措施提供基础数据。方法采用随机整群抽样从哈尔滨等6个大城市抽取6-13岁小学生7082名,使用问卷调查收集他们的年龄、性别及家庭经济情况、牛奶饮用频率等信息。按照标准程序测量身高、体重、腰围、血压,采集晨起空腹血测定血糖、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇和甘油三酯等指标。结果饮用牛奶频率为每周7次以上、7次、1-6次和基本不喝奶的4组儿童中,肥胖率[比值比(OR),95%可信区间(CI)]依次为8.6%(参照组)、10.1%(1.19,0.91-1.56)、11.0%(1.31,1.01-1.70)、12.1%(1.45,1.01-2.10)腹型肥胖率(OR,95%CI)在4组中依次为:12.9%(参照组)、13.7%(1.07,0.85-1.34)、15.7%(1.25,1.00-1.55)、15.6%(1.25,0.91-1.72)高甘油三酯血症率(OR,95%CI)在各组中依次为:2.6%(参照组)、4.0%(1.58,1.00-2.50)、4.2%(1.67,1.07-2.61)、4.6%(1.83,1.00-3.34)调整了混杂因素后,各组间肥胖、腹型肥胖、高甘油三酯血症率仍有显著差并.其他肥胖相关代谢异常率无显著差异结论适量喝牛奶与大城市儿童较低的肥胖率、腹型肥胖率、高甘油三酯血症率有关,应大力提倡儿童饮用牛奶以利于他们的健康成长。
Objective To analyze the relationship between the frequency of milk drinking and obesity and abnormal rate of metabolic index in children and provide the basic data for formulating interventions of the corresponding diseases. Methods A total of 7082 primary school students aged 6-13 were selected from 6 large cities in Harbin by random cluster sampling and their age, gender, family economic status and milk drinking frequency were collected by questionnaire. Height, weight, waist circumference and blood pressure were measured according to standard procedures. Fasting blood samples were collected for blood glucose, total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol, triglyceride and other indicators. Results The obesity rate [odds ratio (OR), 95% confidence interval (CI)] among the 4 groups of children who drank milk more than 7 times per week, 7 times, 1-6 times, and basically did not drink milk were 8.6 (OR, 95% CI) of 12.1% (1.45,1.01-2.10) in the control group (control group) were 10.1% (1.19,0.91-1.56), 11.0% (1.31,1.01-1.70) The rates of hypertriglyceridemia (OR, 95%) were 15% (12.9%), 13.7% (13.0% % CI) were adjusted in 2.6% (reference group), 4.0% (1.58,1.00-2.50), 4.2% (1.67,1.07-2.61), 4.6% (1.83,1.00-3.34) in each group There was still a significant difference between obesity, abdominal obesity and hypertriglyceridemia among all groups.No significant difference was found in other obesity-related metabolic abnormalities.Conclusion The moderate obesity, abdominal obesity, Rate, high blood triglyceride rate, should vigorously promote children’s drinking milk in order to facilitate their healthy growth.
