Background: Epidemiological data shows globally increasing numbers of obesity and stress-related diseases. In this article, a comprehensive medical lifestyle modification programme - called Individual Health Management (IHM) - is described in detail and discussed as a promising tool to individually manage and reverse such negative health trends in patients. Methods: The IHM programme is based on a blended learning concept. It comprises a 12-week basic training phase, followed by a 9-month maintenance phase, and includes the following key features: 1) web-based and physician-led health screenings; 2) a structured 12-week basic training with a core curriculum providing tuition in behavioural self-management strategies for weight loss and stress reduction; 3) weekly supervised group sessions during the core curriculum; 4) tailoring of materials, strategies and lifestyle goals; 5) continuous self-monitoring and feedback of the achieved progress; 6) regular contact with physicians or health professionals based on either face-to-face or distant lifestyle counselling; 7) recurrent one-day health seminars to ensure the sustainability of obtained results. Conclusions: IHM is a multi-component lifestyle intervention programme to increase physical activity, to reduce calorie intake and to practice both self and stress management. Individual care, group support and a tailored web-based programme blend to achieve the desired goals. A randomised control study to evaluate IHM's effects on weight control is currently being conducted.

BackgroundOverweight is considered an important risk factor for diseases in the context of metabolic syndrome. Lifestyle modifications are the means of choice to reduce weight in persons with a Body Mass Index of 28 to 35. The study examines whether there are any differences between two intervention strategies regarding weight reduction in overweight persons.Methods/DesignThe study is a multicentre randomized controlled trial with observation duration of 12 months. Eight study centres are involved to include a minimal sample size of 150 participants. Randomization ratio is 2:1. Feasible persons are checked according to inclusion and exclusion criteria and after given informed consent are assigned randomly to one of two intervention programs: A) intervention group: comprehensive lifestyle modification program (Individual Health Management IHM) with 3 months reduction phase plus 9 months maintaining phase, B) control group: written information with advice for healthy food habits (Usual care UC). Participants of the IHM group have access to a web-based health portal and join 3 full-day and 10 two-hour training sessions during the first 3 months. During the remaining 9 months four refresh trainings will be performed. There are 3 different diet strategies (fasting, two-day diet, meal replacement) for free choice. Participants of the control group are provided with acknowledged rules for healthy food according to the German Nutrition Society (DGE). Examinations are conducted at baseline, after 3, 6, 9 and 12 months. They include body weight, waist circumference, blood pressure, laboratory findings and a bio-impedance analysis to measure body composition. Statistical analysis of the primary outcome ‘change of body weight after 12 months’ is based on ITT population including analysis of variance of the weight differences between month 0 and 12 with the factors ‘group’, ‘baseline value’ and ‘study centre’. Secondary outcomes will be analyzed exploratively.DiscussionThe monitoring of the study will implement different measures to enhance compliance, avoid attrition and ensure data quality. Based on a blended learning concept and using web-based e-health tools the program promises to achieve sustainable effects in weight reduction.Trial registrationGerman Clinical Trials Register Freiburg (DRKS): DRKS00006736 (date registered 20/09/2014).Electronic supplementary materialThe online version of this article (doi:10.1186/s40608-015-0069-x) contains supplementary material, which is available to authorized users.

Zusammenfassung Das Individuelle Gesundheits-Management (IGM) als Lebensstil-Programm kombiniert ein modernes webbasiertes Gesundheitsportal mit einer pers?nlichen Gesundheitsbegleitung in Form von Beratung, Seminaren, Kursen und kur?rtlichen Gesundheitsaufenthalten (?blended learning-Konzept?). Es zielt auf die Gesundheitsf?rderung, Krankheitspr?vention und Patientenschulung von Herz-Kreislauf- und Stoffwechselerkrankungen sowie Stressfolgesch?den und will den Einzelnen ?zum Manager seiner eigenen Gesundheit? machen. Prim?re Settings sind die Kommunen, Betriebe und das medizinische Versorgungsklientel. Das Vorhaben versteht sich als Demonstrationsprojekt zur St?rkung einer proaktiven Versorgung der regionalen Bev?lkerung. Das inhaltliche Konzept ?pr?fen ? planen ? praktizieren? umfasst ein 12-w?chiges Basistraining mit einer mindestens 9-monatigen Aufbau- oder Erhaltungsphase.

Hintergrund Typische Gründe für die Inanspruchnahme von Komplementärmedizin in der Onkologie sind u.a. schlechte Lebensqualität, ein höheres Erkrankungsstadium, positive Vorerfahrung mit komplementären Methoden und ein höherer Sozialstatus. Häufig bestehen Erwartungshaltungen seitens der Patienten (gelegentlich auch von Ärzten und Heilpraktikern) an die Komplementärmedizin, dass diese evidenzbasierte Behandlungsalternativen zur konventionellen Onkologie anbieten könnte. Dies kann bis heute nicht belegt werden. Die Betroffenen, die sich noch in der aktiven Behandlungsphase (Operation, Chemotherapie, Strahlentherapie u.a.) befinden, verfolgen mit der Anwendung von Naturheilkunde und Komplementärmedizin häufig die Reduktion von Nebenwirkungen der konventionellen Tumortherapie, aber auch eine aktive Stärkung der Gesundheit [6, 10, 17]. Es besteht oft der Wunsch, sich aktiv am Therapiegeschehen zu beteiligen. Menschen, die die konven-
