Effect of a convenience intervention program for lifestyle modification in physical activity and nutrition (LiSM10!) in middle-aged male office workers: A randomized controlled trial

PurposeThe purpose of this study was to investigate the effects of a convenience intervention program (LiSM10!) based on a support program for employee health promotion through lifestyle modification in physical activity and nutrition (LISM-PAN) in middle-aged male office workers.Study designA randomized controlled trial at a worksite.MethodsThirty-eight eligible male office workers at a food company in Japan were randomly allocated into two groups. The intervention group (n = 19) attended three counseling sessions and received one e-mail-based advice over a 6-month period. Each session included two 10-min counseling sessions with an exercise instructor and a certified dietician trained in behavioral change theories and practical techniques. The control group (n = 19) received only conventional written advice based on their baseline measurements.ResultsIn total, 89% of the participants completed the program and were included in the analysis. No significant differences in the baseline characteristics of the two groups were observed. The body mass index, high density lipoprotein cholesterol and alanine aminotransferase levels in the intervention group were significantly more improved than in the control group.ConclusionThe present results indicated that the convenience program was effective and more applicable than intensive programs to reduce the risk of lifestyle-related diseases in middle-aged male office workers.
