目的探究人群累积主食摄入量的估算方法。方法采用江西大余县人群3次膳食调查的汇总数据,用曲线拟合的方法,拟合人群年龄累积大米消费量曲线方程。结果人群年龄累积大米消费量的曲线方程为:男性y=-0.2255x~2+152.19x-391.68,女性y=-0.0985x~2+110.41x-150.03,曲线拟合良好(R_男2=0.9989,R_女2=0.9992)。结论在以大米作为主食的地区,可利用大米消费量曲线方程(分性别间)来估算当地人群各年龄段的累积大米消费情况。
Abstract：Objective To explore the method for estimating the cumulative staple food intake of resident. Methods A curve fitting equation based on three dietary survey data of resident in Dayu County of Jiangxi Province was established. Results The equation were y =- 0. 2255x~2+ 152. 19x- 391. 68 for male and y =- 0. 0985x~2+110. 41x- 150. 03 for female. And the curve fitting were good( RM~2= 0. 9989,RF~2=0. 9992). Conclusion In the area that rice is the stable food,the curve equation can be used to estimate the cumulative rice consumption of resident.
