Conditions studied: Obesity Prevention

In brief

This pilot study will focus on men and women aged ≥60 years for a period of 3 months during which each participant will use the HLRS. The primary purpose is to study whether the HLRS, reflecting a multi-component intervention, is well accepted by the participant, has a decent adherence (i.e., user time of the app). In addition, investigators will study the feasibility of the design, i.e. whether the overall design is well suited to the participants, in order to improve their lifestyle, e.g., dietary habits and PA, among others. Secondary outcomes related to the feasibility approach include dietary habits, PA patterns, and selected plasma and urinary endpoints. This pilot study will be of longitudinal design without a control group. A later trial that is planned for the following year will focus further on biological endpoints and will be randomized. In this present pilot study, investigators aim to assess mainly the user-friendliness of the HLRS, and gather first evidence that the intervention can indeed produce healthier lifestyle patterns. The study's primary objective is to determine whether the developed HLRS can be successfully applied to the target population (men and women aged ≥60 years) and whether they use it frequently during the study and are satisfied with the HLRS. Secondly, investigators will study whether the assessment of endpoints required for the later and separately planned ensuing long-term study can be well assessed within the study and if, despite the limited time of the intervention duration, the intervention will be able to preliminary improve specific markers related to the risk of obesity and associated comorbidities. This will entail anthropometric measures to assess changes in body mass and body fat in addition to the primary and secondary objectives.
