![]() %include ‘c:\sas\growth charts\who\data\WHO-source-code.sas’ run Step 4: Copy and paste the following line into your SAS program after the line (or lines) in step #3. It’s unlikely that the SAS code will overwrite other variables in your dataset, but you should avoid having variable names that begin with an underscore, such as _bmi. Z-scores and percentiles for variables that are not in mydata will be coded as missing (.) in the output dataset (named _whodata). Sex (coded as 1 for boys and 2 for girls) and agedays must be in mydata. īMI (weight (kg) / height (m) 2). If your data doesn’t contain BMI, the program calculates it. If BMI is present in your data, the program will not overwrite it. Recumbent length in cm. If standing height (rather than recumbent length) was recorded, add 0.7 cm to the values (see. If age is known only to the completed number of weeks (e.g., 5 weeks of age would represent any number of days between 35 and 41), multiply by 7 and consider adding 4 (median number of days in a week). If age is known only to the completed number of months, multiply by 365.25/12, and consider adding 15. VariableĬhild’s age in days must be present. If this value is not an integer, the program rounds to the nearest whole number. Instructions for SAS users (step 3), guidance on renaming and coding variables in your dataset. If you’re not using SAS, you can download WHOref_d.cvs, and create a program based on who-source-code.sas to do the necessary calculations. This reference data set combines values from several WHO datasets. The SAS program, WHO-source-code.sas (files are below, in step #1), calculates these z-scores and percentiles based on reference values in WHOref_d.sas7bdat. Although WHO provides several macros and a PC program for these calculations, this SAS program follows the same steps as does the SAS program for the CDC growth charts. Additional details about the ages for which the various z-scores and percentiles are calculated are given in Table 2 (below). Observations that contain extreme values ( absolute z-scores above 5 or 6 ) are flagged as being biologically implausible. Weight-for-height z-scores and percentiles are also calculated. If you witness or are subject to unacceptable behaviour, file an official report at who will take appropriate action and report the incident to ACM if necessary.The purpose of this SAS program is to calculate the percentiles and Z-scores (standard deviations) for a child’s sex and age from birth up to 2 years of age for BMI, weight, height, skinfold thicknesses (triceps and subscapular), arm circumference, and head circumference based on the WHO Growth Charts. Conference participants violating these standards may be expelled from this and future conferences. ![]() There is no tolerance for unwelcome, hostile, or disruptive behavior or speech that intimidates, creates discomfort, or interferes with a person’s participation or opportunity for participation at the conference and all associated events. We expect all the participants to use welcoming and inclusive language, to be respectful of differing viewpoints and experiences, to gracefully accept constructive criticism, to focus on what is best for the community, and to show empathy towards other community members. ![]() In particular, attendees and organisers must abide by the ACM Policy Against Discrimination and Harassment. SIGPLAN is dedicated to providing harassment- and discrimination-free conference. ![]() Special circumstances may be discussed with the general chair.Īnti-harassment and non-discrimination: The open exchange of ideas and the freedom of thought and expression are central to the aims and goals of SIGPLAN these require an environment that recognizes the inherent worth of every person and group, that fosters dignity, understanding, and mutual respect, and that embraces diversity.
