【目的】 探索单次和多次健康教育对肥胖儿童认知,饮食结构、生活方式及体重控制的影响,为儿童肥胖干预的实施提供有效措施。 【方法】 按照《中国0~18岁儿童青少年体块指数的生长曲线》超重和肥胖诊断标准筛查学龄儿童,对肥胖儿童发放调查问卷,评估肥胖认知、饮食结构及生活方式并分组给予单次或多次健康教育。健康教育的内容包括肥胖的判断和危害,科学的饮食结构、生活方式和心理支持等。6个月后再次进行评估。 【结果】 共有107名年龄6~13岁的肥胖儿童(男69人,女38人)纳入研究。资料完整90名,其中单次教育组44人,多次教育组46人。1)健康教育后两组儿童和家长对肥胖的认知水平均提高,但多次教育组儿童和家长认知水平显著高于单次教育组(P<0.01);2)干预后,多次教育组总能量及蛋白质、脂肪、碳水化合物摄入量及能量密度均降低(P<0.01),蔬菜份量增加(P<0.05),动物性食物及甜点、薯片的进食份额明显减少(P<0.01);单次教育组脂肪摄入减少(P<0.01),但总能量、食物份额量无明显改变;3)多次教育组在洋快餐、零食、看电视吃零食频率及看电视时间明显减少(P<0.01),但每日运动时间无明显变化;单次教育组生活方式无显著改变(P>0.05);4)干预后单次教育组BMI-SDS(body mass index-standard deviation score )无明显改变,多次教育组BMI-SDS降低(P<0.05)。 【结论】 对肥胖儿童和家长进行健康教育,尤其是多次教育有助于提高肥胖儿童和家长认知能力,降低儿童总能量摄入,改变饮食结构和生活方式,进而降低BMI。
Abstract
【Objective】 To explore the impacts of single and repetitive health education on the cognition,diet,lifestyle and weight control in obese children,and provide effective measures to childhood obesity intervention. 【Methods】 According to "Body mass index growth curves for Chinese children adolescents aged 0 to 18 years "diagnostic criteria for screening obesity in school-age children.Obese children and their parents were distributed questionnaires to assess cognition of obesity,diet and lifestyle and then were assigned single or repetitive education.Six months later,the obese children and their parents were asked to complete the questionnaires again for evaluating health education effects on cognition,diet and lifestyle and weight control. 【Results】 107 obese children ( 6 to 13-year-old,69 boys,38 girls) were involved into the intervention study and 90 obese children were completed.There were 44 obese children in single education group and 46 obese children in repetitive education group.At 6 months' follow-up,1) Cognition:Both of children and parents in two groups on the cognitive had increased,particular in children (P=0.008) and parents (P=0.003) of repetitive education group.2) Dietary survey:total energy,protein,fat,carbohydrate intake,food energy density of the lunch and dinner,single meal size (lunch size and dinner size) were significantly decreased in repetitive education group (P<0.001),while the meal size was not any change in single education group (P>0.05).3) Lifestyles:had significantly decreased in high fat food,snacks,watching TV,snacking,watch TV time(P<0.001)in repetitive education group but not in single education group (P>0.05).4) Body Mass Index (BMI):During the follow-up,the mean BMI-Standard Deviation Score (BMI-SDS) was decreased in repetitive education group(P<0.01)but not in single education group(P>0.05). 【Conclusion】 Health education,especially repetitive education could change obese children on cognitive ability,total energy intake and lifestyle,thereby reducing BMI.
