Abstract
OBJECTIVES The aim was to investigate whether lifestyle changes produced by persuasive Information and Communication Technology (ICT) counselling can lower the prevalence of metabolic syndrome (MetS). METHODS A total of 532 participants (20-60 years, body mass index 27-35 kg/m2) were randomly assigned to six arms according to counselling type (no, short-term, or intensive) with or without ICT intervention. In this report the prevalence of MetS and its components were compared between no-ICT group and ICT group. Moreover, the frequency of the web information system usage was analysed for the number of logins, responses to weekly messages, and other record variables. RESULTS The ICT group had significantly lower proportion of MetS (33.7% vs. 45.3%, p = .022) than the no-ICT group at 2-year follow-up. In mixed model, the ICT group had lower prevalence of MetS than no-ICT group (OR 0.50, 95%CI 0.27-0.90) after intervention. The tertile with the highest utilization had 71% lower prevalence of MetS compared with the lowest utilization tertile or the no-ICT group. CONCLUSIONS Web-based ICT is able to reduce the prevalence of MetS. In addition, higher utilization of the web information system is associated with a greater decrease in the prevalence of MetS. Key messages Our internet health behaviour change support system based on persuasive design and cognitive behaviour therapy markedly reduces metabolic syndrome in overweight/obese subjects. As a stand-alone tool it may save healthcare personnel resources as it is suitable at a low cost for both obese/overweight patients and the public at large.

Abstract
PURPOSE To evaluate the efficacy, safety and availability of a 12-week, community-based obesity control program called the Protein-Rich Oriental Diet (PRO Diet) and to compare it to a conventional diet. MATERIALS AND METHODS A total of 515 overweight people (55 men and 460 women; mean age 41.9 ± 9.8 years; body mass index (BMI) 28.1 ± 3.6 kg/m²) participated in the program at two public health centers. PRO Diet was offered as the main diet recommendation for 12 weeks. As a control group, we selected a population who had followed a conventional diet program conducted at a public health center in 2006. RESULTS 177 subjects (34.3%) completed the 12-week PRO Diet program. In a per protocol (PP) analysis, the mean changes in anthropometry were (conventional program vs. PRO Diet; weight, -2.3 kg vs. -4.7 kg, p < 0.001; BMI, -1.1 kg/m² vs. -1.9 kg/m², p < 0.001; waist circumference, -3.3 cm vs. -6.8 cm, p < 0.001; fat mass, -2.0 kg vs. -4.2 kg, p < 0.001; fat % mass, -1.8% vs. -3.9%, p < 0.001). The triglyceride reduction was significantly greater (-30.16 mg/dL, p < 0.001) in the PRO Diet group after intervention compared to the conventional group. CONCLUSION The PRO Diet was an effective tool for weight loss in a community-based weight control program and well-tolerated.

Abstract
Many obese people who try to control body weight experience weight cycling (WC). The present study evaluated the importance of WC in a community-based obesity intervention program. We analyzed the data of 109 Korean participants (86% women) among 177 subjects who had completed a 12-week intervention program at two public health centers in Korea from April to December, 2007. Completion of a self-administrated questionnaire at baseline was used to obtain anthropometric measurements, and laboratory testing was done before and after the program. Differences in body composition change and obesity-related life style between the two groups were compared with respect to WC and non-weight cycling (NWC). After 12 weeks, both groups showed reductions in weight, waist circumference, and body mass index. The group differences were not significant. However, significant differences were evident for the WC group compared to the NWC group in fat percent mass (WC vs. NWC, -3.49+/-2.31% vs. -4.65+/-2.59%, P=0.01), fat free mass (WC vs. NWC, -0.95+/-1.37 kg vs. -0.38+/-1.05 kg, P=0.01), and total cholesterol (WC vs. NWC, -3.32+/-14.63 vs. -16.54+/-32.39, P=0.005). In conducting a community-based weight control program that predominantly targets women, changes of body composition and total cholesterol may be less effective in weight cyclers than in non-weight cyclers.
