Internet-based CPA smart lifestyle program for preventing abdominal obesity in Japanese workers

Abstract

Objectives: Abdominal obesity is a major public health concern. We have developed CPA [Check-Plan-Action] smart lifestyle program to prevent abdominal obesity. The purpose of this study was to examine the efficacy of this internet-based program in Japanese workers. Methods: Forty five subjects (Men:44.4%, Mean age:44.0+/-10.6 years, Body Mass Index: 24.0+/-3.4 kg/m2) received a CPA booklet, a pedometer, and a mobile-based self-monitoring system ID. According to the CPA booklet, they set two or three behavioural goals (PA or nutrition), they monitored their goal attainment, weight and daily walking step for 3 months via internet. Results: After 3 months, waist circumference was significantly lost (Pre: 86.3+/-9.7, Post: 85.0+/-10.4 [cm]). HbA1c (Pre: 4.9+/-0.4, Post: 4.8+/-0.4 [%]) and HDL-cholesterol (Pre: 67.3+/-15.6, Post: 70.8+/-16.8 [mg/dl]) were significantly improved after 3 months. The most adhered participants lost waist circumference more than other participants. Conclusions: These results suggested that internet-based CPA smart lifestyle program may have short-term effects on weight control and some metabolic risk factors.
