Abstract
Objective: We have been conducting the lifestyle intervention program "Diet Support Plan Group Challenge" (DSP-G) since 2006. In this study, we aimed to clarify whether program participants could maintain improvements in various biochemical data and weight loss after finishing the program.
Methods: Participants were a total of 60 Japanese male office workers who underwent health check-ups in 2006 and had one or more of the following objective findings: body mass index (BMI, kg/m2) 25≦, hypertension, hyperglycemia, dyslipidemia, hyperuric academia or liver dysfunction. They started the DSP-G between November and December 2006 and finished it between February and March 2007. Biochemical data obtained in health check-ups in 2006, on finishing the DSP-G program and in follow-up health check-ups performed between May 2007 and January 2008 were compared.
Results: Forty-three participants completed the program and underwent health check-ups in 2007. Body weight was significantly decreased after finishing the DSP-G program (77.2± 8.6 to 73.4± 8.9kg, p<0.0001) and this improvement was maintained until the follow-up health check-ups in 2007 (73.2±10.2 kg). Similar tendencies were observed for biochemical data.
Conclusion: Our results suggest that the lifestyle improvements achieved by the DSP-G program were maintained by the participants for at least 1 year.
