【摘要】：目的了解成都市龙泉驿区学龄儿童膳食消费支出与体质指数(BMI)的关系,为儿童超重肥胖的预防控制提供理论依据。方法采用分层整群抽样法,选取成都市龙泉驿区371名7~12岁儿童作为研究对象。通过问卷调查收集儿童的基本信息、家庭情况及膳食摄入信息。根据政府数据和市场调查确定食物单价,结合摄入量计算每日膳食花费。现场测量儿童的身高、体重,计算BMI和体质指数标准差评分(BMI Z-评分)。使用多重线性回归模型分析膳食花费与BMI Z-评分的关系。结果调整年龄后,男生膳食花费与BMI Z-评分呈正相关关系(β=0.015,P=0.04),女生中未发现两者间的关系。结论膳食花费较高的男生,其BMI Z-评分也较高。今后在制定儿童超重肥胖的防控措施时应考虑经济因素的影响。
[Abstract]:Objective to investigate the relationship between dietary expenditure and body mass index (BMI) of school-age children in Longquanyi District, Chengdu, and to provide theoretical basis for prevention and control of overweight and obesity in children. 371 children aged 7 to 12 years old in Longquanyi District of Chengdu City were selected as the research objects. The basic information, family situation and dietary intake information of children were collected through questionnaires. The unit price of food was determined according to government data and market survey. Daily dietary costs were calculated in combination with intakes. Height and weight of children were measured in the field. BMI and BMI standard deviation scores were calculated. Multiple linear regression models were used to analyze the relationship between dietary cost and BMI Z- score. There was a positive correlation between dietary cost and BMI Z- score in male students (尾 0.015 P0.04%), but there was no relationship between them in female students. Its BMI Z- score is also high. Economic factors should be taken into account in formulating prevention and control measures for overweight and obesity in children in the future.
