NHANES Directly Measured BMI data

Directly measured NHANES data are stored in NHANES DM.csv in CSV format. This file contains four columns: year t, BMI in year t, age in year t, and gender. Note: We associate NHANES data from survey 1999-2000 with t = 1999, from survey 2001-2002 with t = 2001, and so on.直接测量获取的美国国家健康与营养检查调查（National Health and Nutrition Examination Survey，NHANES）数据以逗号分隔值（Comma-Separated Values，CSV）格式存储于NHANES DM.csv文件中。该文件包含四列字段，分别为调查年度t、t年度的身体质量指数（Body Mass Index，BMI）、t年度的年龄以及性别。注：本数据集将1999-2000年调查的NHANES数据对应至t=1999，2001-2002年调查的数据对应至t=2001，以此类推。
