Study design
MAY
This study was a randomised pilot trial. The experimental group received a 5-week NL online intervention programme between April and May 2018, including a 30-min lesson/week, whereas the control group did not receive any nutrition education intervention. Each participant in the experimental group was assigned a set of accounts and passwords to log into the course and complete it within the specified time. The research assistant would send an email or text message to remind the participants when each unit of the online course was open and whenever the participants had not completed the online course within the time limit. All students who took part in the research project completed all online courses. Both groups were asked to complete the pretest and post-test online questionnaires prior to and after completion of the online programme, respectively.
