  abstract  = {Non-communicable diseases (NCD) are associated with high costs for healthcare systems. We evaluated changes in total costs, comprising direct and indirect costs, due to a 24-month non-randomized, controlled lifestyle intervention trial with six measurement time points aiming to improve the risk profile for NCDs. Overall, 187 individuals from the general population aged ≥18 years were assigned to either the intervention group (IG; n = 112), receiving a 10-week intensive lifestyle intervention focusing on a healthy, plant-based diet; physical activity; stress management; and community support, followed by a 22-month follow-up phase including monthly seminars, or a control group (CG; n = 75) without intervention. The complete data sets of 118 participants (IG: n = 79; CG: n = 39) were analyzed. At baseline, total costs per person amounted to 67.80 ± 69.17 EUR in the IG and 48.73 ± 54.41 EUR in the CG per week. The reduction in total costs was significantly greater in the IG compared to the CG after 10 weeks (p = 0.012) and 6 months (p = 0.004), whereas direct costs differed significantly after 10 weeks (p = 0.017), 6 months (p = 0.041) and 12 months (p = 0.012) between the groups. The HLCP-2 was able to reduce health-related economic costs, primarily due to the reduction in direct costs.},

  abstract  = {Aim Since unhealthy lifestyle behaviors, risk factors for noncommunicable diseases (NCDs), and diseases themselves can independently influence quality of life, lifestyle intervention programs addressing all of these may yield benefits for quality of life. This study aimed to examine the impact of the Healthy Lifestyle Community Program (HLCP-2) on quality of life in adults. Subject and methods Data stem from a 24-month, non-randomized controlled lifestyle program which aimed to improve markers of NCD risk. Overall, 187 participants were assigned to either the intervention group (IG; n = 112) receiving a 10-week intensive lifestyle intervention on plant-based diet, physical activity, stress management, and community support, followed by a 22-month alumni phase, or a control group (CG; n = 75), without intervention. Quality of life was assessed by the EQ-5D-3L questionnaire at six measurement time points. Problems in five health dimensions ("mobility", "self-care", "usual activities", "pain/discomfort," and "anxiety/depression"), a visual analogue scale on self-rated health (EQ VAS), and the German EQ-5D index were addressed. Results At baseline, 59.8\% of the IG and 59.4\% of the CG reported problems in ≥ 1 health dimension, with improvement in the IG at all time points. Compared to baseline, the EQ VAS increased significantly in the IG compared to CG at all time points. The mean EQ-5D index tended to improve in the IG, but changes did not differ significantly from changes in the CG. Conclusion A lifestyle community program addressing lifestyle behaviors provides benefits for participants' self-rated health status, with the greatest effect after the intensive phase.
