浙江省7～12岁儿童营养相关疾病现状分析

Status of Diseases Related to Nutrition Among Children Aged 7-12

目的分析浙江省7～12岁儿童主要营养相关性疾病患病状况,为开展针对性干预提供依据。方法采用多阶段分层整群随机抽样方法,抽取浙江省3677名7～12岁儿童为对象,测量身高、体重,检测血液中维生素A和血红蛋白质量浓度。结果儿童血浆维生素A浓度为(1.19±0.35)mmol/L,血红蛋白质量浓度为(132.53±12.11)g/L,亚临床维生素A缺乏(SVAD)和可疑维生素A缺乏患病率分别为5.46%和35.90%,贫血患病率为12.56%,超重和肥胖患病率分别为7.51%和4.46%。农村儿童SVAD、可疑SVAD、贫血患病率高于城市儿童,城市儿童超重、肥胖患病率高于农村儿童;男童可疑SVAD、超重和肥胖患病率高于女童。结论应采取有效的干预措施,降低学龄儿童营养相关疾病的发生率。

Objective To study the status of nutrition related diseases, and to develop the effective intervention to children. Methods With random sampling method, 3 677 children were chosen. Their body weight and height were measured, and VA and hemoglobin level were determined. Results The plasma VA mean level of children was 1.19 ± 0.35 mmol/L, and hemoglobin level was 132.53 ± 12.11 g/L. The prevalence of sub-clinical VA deficiency （ SVAD ） and suspected SVAD were 5.46 % and 35.90 %, and the prevalence of anemia, overweight and obesity were 12.56 % 7.51% and 4.46 % respectively. The prevalence of anemia, SVAD and suspected SVAD of children in rural area were higher than those in urban area. The prevalence of suspected SVAD, overweight and obesity of boys were higher than those of girls. Conclusion Effective measures should be implemented to decrease the prevalence of nutrition-related diseases.
