摘要:
了解儿童青少年营养状况和减肥行为的流行现状,为探索体重认知与减肥行为的关联提供参考.方法 在2012年卫生公益性行业科研专项全国7个示范基地共选取53 890名中小学生为研究对象,进行体格检查和问卷调查,收集儿童青少年减肥行为与体重认知相关资料.采用多元Logistic回归分析体重认知相关变量与减肥行为的关联.结果 6~18岁儿童青少年消瘦检出率为6.9%,超重肥胖检出率为24.3%.采取过减肥行为的小学生检出率为58.5%,初中生为65.9%,高中生为60.4%.在消瘦学生群体中,体重不满不会增加减肥行为的发生(P=0.29);而认为自己偏胖会增加减肥行为的发生(OR=5.28,95%CI=2.76~ 10.12,P<0.01).在体重正常学生群体中,对自己体重不满或认为自己体重偏胖的学生更容易采取减肥行为(OR=1.09,95%CI=1.03~ 1.16,P<0.01;OR=1.57,95%CI=1.44~1.71,P<0.01).在超重肥胖的学生中,对自己体重不满和认为自己偏胖均会增加减肥行为的发生(P值均<0.01).结论 中国儿童青少年超重肥胖率和减肥行为发生率较高.体重不满是正常体重和超重肥胖学生采取减肥行为的危险因素,且认为自己偏胖是儿童青少年采取减肥行为的危险因素.
Abstract:
Objective To evaluate the prevalence of different nutritional status and weight-loss behaviors of children and adolescents in 7 provinces and cities in China,and to provide references for exploring the association between weight-loss behaviors and weight-related perceptions among Chinese children and adolescents.Methods A total of 53 890 primary and middle school students from seven regions in China participated in physical examination and questionnaire survey,and the information about their weight-loss behaviors and weight-related perceptions was collected.The distribution of nutritional status and weight-loss behaviors in children and adolescents were described.And multiple logistic regression analysis was applied to the association between weight-loss behaviors and weight-related perceptions.Results The prevalence of underweight and overweight were 6.9% and 24.3% respectively.The prevalence of taking weight-loss behaviors among primary middle students was 58.5%,among middle school students was 65.9%,among high school students was 60.4%.In the underweight group,no significant effect between weight dissatisfaction and weight-loss behaviors was found(P=0.29);considering themselves as overweight could increase the occurrence of weight-loss behaviors(OR=5.28,95%CI=2.76-10.12,P<0.01).In the group of normal weight,weight dissatisfaction will promote weight-loss behaviors(OR=1.09,95%CI=1.03-1.16,P<0.01,OR=1.57,95%CI=1.44-1.71,P<0.01).In overweight group,weight dissatisfaction and conception of overweight will promote weight-loss behaviors(P<0.01).Conclusion The prevalence of overweight and weight-loss behaviors are high among Chinese children and adolescents.Weight dissatisfaction will promote the students of normal weight and overweight students to take weight-loss behaviors.The conception of overweight is the risk factor of the weight-loss behaviors in all groups.
