Personalized counseling
VHV
ADVERSE EVENTS
Well-trained VHV visited the participants at home once weekly for 20 weeks. Following the established procedure, the VHV engaged the participants during the home visit by greeting them and inquiring about their thoughts and any potential negative side effects of the weight-loss program. Additionally, the VHV also encouraged the participants to continue the hypocaloric diet following the example of a recipe, physical exercise, and daily self-weighing with a record. Furthermore, the VHV would notify the field research coordinators and registered nurses who worked at the Baan Na-Yao Health Promoting Hospital if adverse events were reported.
