摘要:
了解中国6省市儿童青少年代谢综合征(MS)流行现状及其与进食速度的关系,为儿童青少年代谢性疾病防控策略和干预措施的制定提供科学依据.方法 对分层整群抽取的我国12 958名儿童青少年进行问卷调查、体格检查和血生化检测.描述儿童青少年MS、进食速度的分布特征,采用多因素Logistic回归模型分析进食速度与MS的关系.结果 我国六省市7~17岁儿童青少年MS检出率为4.2%,男生高于女生(x2=13.65,P<0.05);随着年龄段增加,检出率呈升高趋势(x2=31.26,P<0.05).中心性肥胖是检出率最高的代谢异常组分(22.7%).男、女生除血糖外的代谢指标均随着进食速度从慢到快呈现趋势变化,差异均有统计学意义(P值均<0.05).多因素Logistic回归分析结果显示,进食速度与儿童青少年MS及代谢异常组分发生存在关联性,中心性肥胖与进食速度关联性最强.男、女生进食速度慢是MS的保护因素(男生OR=0.311,95%CI=0.199 ~ 0.487;女生OR=0.497,95%CI=0.304~0.814).男生进食速度慢是中心性肥胖、高血压、高三酰甘油血症、脂代谢异常的保护因素,而女生进食速度慢是中心性肥胖、高三酰甘油血症、脂代谢异常的保护因素(P值均<0.05);进一步调整BMI后关联性均消失.结论 进食速度慢是儿童青少年MS及一些代谢异常组分发生的保护因素.在加强饮食干预时要注意儿童青少年进食方式习惯的养成.
Abstract:
Objective To evaluate the prevalence of metabolic syndrome (MS) of children and adolescents in 6 provinces and cities in China,to analyze the relationship between eating speed and MS,and to provide scientific basis for the prevention and control strategies of metabolic disease of children and adolescents.Methods A total of 12 958 children and adolescents from 6 provinces and cities of China participated in physical examination,questionnaire survey and blood biochemical tests.The difference between MS and sex,age were evaluated by using t test,and the association between eating speed and MS was evaluated by using multiple Logistic regression model.Results The prevalcncc of MS of children and adolescents aged 7-17 was 4.2% in 6 provinces and cities in China,more boys were detected with MS than girls(x2 =13.65,P<0.05),and the rate increased with the increase of age (x2 =31.26,P<0.05).Abdominal obesity were diagnosed as the commonest MS(22.7%).All the physiological and metabolic indexes showed significant trend from slow eating speed to fast eating speed (P<0.05),except for blood glucose.Results from multivariate Logistic regression analysis showed that eating speed was significantly associated with MS and some metabolic abnormalities,and abdominal obesity was of greatest relevance to eating speed.In both boys and girls,slow eating speed was the protective factor of MS(OR=0.311,95%CI=0.199-0.487;OR=0.497,95%CI=0.304-0.814).In Boys,slow eating speed was a protective factor for abdominal obesity,hypertension,low HDL-C,high TAG,while slow eating speed was a protective factor for central obesity,low HDL-C and high TAG in girls.After further adjustment for BMI,all associations disappeared.Conclusion Slow eating speed is a protective factor for MS and some metabolic abnormalities.Attention should be paid to the development of eating habits in the diet intervention among children and adolescents.
