【摘要】：目的了解成都市龙泉驿区7~12岁儿童膳食质量与膳食消费支出的关系,为相关政策的制定提供理论依据。方法采用分层整群抽样法,选取成都市龙泉驿区483例7~12岁儿童作为研究对象,通过问卷调查的方法收集儿童基本信息、家庭经济情况、膳食摄入信息以及静态生活方式时间。采用中国儿童膳食指数(Chinese children dietary index,CCDI)评价儿童的膳食质量。根据政府发布数据和市场调查结果确定食物单价,并结合膳食摄入量计算儿童每日膳食花费。使用多重线性回归模型分析膳食质量与膳食消费支出的关系。结果调整年龄、性别和能量后,成都市7~12岁儿童的膳食质量与膳食消费支出呈正相关(β=0.049 9,P=0.02)。儿童的膳食指数得分每增加一个单位,其膳食消费支出增加0.049 9元。膳食质量最高组的儿童比膳食质量最低组的儿童每日膳食消费总支出高8.9%。结论膳食质量较高的儿童,其膳食花费也较高。在未来的营养干预及公共营养政策制定中,需要将经济因素作为重要的限制因素纳入考虑。
[Abstract]:Objective to investigate the relationship between dietary quality and dietary consumption expenditure of 712 year old children in Longquanyi District, Chengdu, and to provide theoretical basis for the formulation of relevant policies. Methods using stratified cluster sampling method, 483 712 year old children in Longquanyi District of Chengdu were selected as the research objects. The basic information of children, family economic situation, dietary intake information and the time of static life style were collected by questionnaire. Chinese Children's Dietary Index (Chinese children dietary index,CCDI) was used to evaluate children's dietary quality. According to the data released by the government and market survey results, the unit price of food was determined, and the daily dietary cost of children was calculated in combination with dietary intake. The multiple linear regression model was used to analyze the relationship between dietary quality and dietary expenditure. Results after adjusting for age, sex and energy, the dietary quality of children aged 7 to 12 in Chengdu was positively correlated with the expenditure of dietary consumption (尾 = 0.049). For each additional unit of children's dietary index, the expenditure on food consumption increased by 0.049 yuan. The children in the highest dietary quality group were higher than those in the lowest dietary quality group, and the total daily dietary consumption expenditure was 8.9% higher than that in the lowest dietary quality group. Conclusion Children with high dietary quality also have higher dietary costs. Economic factors need to be taken into account as important limiting factors in future nutrition interventions and public nutrition policy formulation.
