Data are means or percentages. A total of 96 participants who started the program after 31 January 2016 with no postcurriculum assessment were excluded. A total of 342 participants did not complete the postcurriculum assessment but returned for at least one annual or midyear assessment, and 29 postcurriculum assessments were missing a weight measurement.
