2、數(shù)據(jù)準備（以2017-2018年周期為例）

需要準備的數(shù)據(jù)：食物模式等效物膳食攝入量；營養(yǎng)攝入情況；人口統(tǒng)計數(shù)據(jù)。

①在食物模式等效物數(shù)據(jù)庫（FPED）下載對應周期的食物模式等效物膳食攝入量文件：

FPED數(shù)據(jù)庫鏈接:

https://www.ars.usda.gov/northeast-area/beltsville-md-bhnrc/beltsville-human-nutrition-research-center/food-surveys-research-group/docs/fped-databases/

下載后解壓得到fped_dr1tot_1718.sas7bdat和fped_dr2tot_1718.sas7bdat兩個文件。②在NHANES數(shù)據(jù)庫對應周期的飲食數(shù)據(jù)當中下載營養(yǎng)攝入情況：DR1TOT_J.XPT和DR2TOT_J.XPT
③在NHANES數(shù)據(jù)庫下載對應周期的人口統(tǒng)計數(shù)據(jù)：DEMO_J.XPT。至此文件夾中一共得到了5個文件3、飲食模型指數(shù)計算（以2017-2018年周期為例）
安裝并加載包和數(shù)據(jù)
