摘要
目的了解宁夏7~18岁儿童青少年的营养状况及其与家长健康知识、态度及行为之间的关系,为儿童青少年超重肥胖干预提供理论依据。方法采用分层整群随机抽样方法,从宁夏银川和吴忠市,按年级分层随机抽取66个班3027名学生及其家长作为调查对象,对学生进行体格检查和问卷调查,同时对其家长进行问卷调查。结果7~18岁儿童青少年超重和肥胖检出率分别为9.4%和6.0%。家长肥胖相关知识的12道题中,“应多吃蔬菜水果”答对率居首位,为98.2%;“中国居民膳食宝塔中越在底层的食物越应该多吃”答对率最低,仅为39.5%。家长对子女体重的认知与子女真实体重之间的Kappa值为0.24,一致性不高,超重肥胖儿童的家长容易低估孩子的真实体重,尤其是男生更容易被家长低估,性别间差异有统计学意义(Z=-8.47,P<0.01)。多因素Logistic回归分析显示,儿童超重肥胖与性别为男、独生子女、剖宫产、父母超重或肥胖和家长低估孩子的体重呈正相关,与出生体重≤2 499g呈负相关。结论宁夏儿童青少年超重肥胖检出率较高,家长对子女体重的低估与儿童超重肥胖相关。应针对家长健康知识的薄弱环节进行健康教育,有助于提升儿童超重肥胖的干预效果。
Objective To explore nutritional status of children and adolescents aged 7-18 in Ningxia,and to explore its association with health knowledge,attitudes and behaviors of their parents.

The Kappa value between parents’ perception of child’s weight with their children’s true weight is 0.24. Parents of overweight and obese children tend to underestimate weight of their children,especially for boys( P< 0.01).
