Introduction The European population is rapidly ageing. In order to handle substantial future challenges in the healthcare system, we need to shift focus from treatment towards health promotion. The PreventIT project has adapted the Lifestyle-integrated Exercise (LiFE) programme and developed an intervention for healthy young older adults at risk of accelerated functional decline. The intervention targets balance, muscle strength and physical activity, and is delivered either via a smartphone application (enhanced LiFE, eLiFE) or by use of paper manuals (adapted LiFE, aLiFE). Methods and analysis The PreventIT study is a multicentre, three-armed feasibility randomised controlled trial, comparing eLiFE and aLiFE against a control group that receives international guidelines of physical activity. It is performed in three European cities in Norway, Germany, and The Netherlands. The primary objective is to assess the feasibility and usability of the interventions, and to assess changes in daily life function as measured by the Late-Life Function and Disability Instrument scale and a physical behaviour complexity metric. Participants are assessed at baseline, after the 6 months intervention period and at 1 year after randomisation. Men and women between 61 and 70 years of age are randomly drawn from regional registries and respondents screened for risk of functional decline to recruit and randomise 180 participants (60 participants per study arm). Ethics and dissemination Ethical approval was received at all three trial sites. Baseline results are intended to be published by late 2018, with final study findings expected in early 2019. Subgroup and further in-depth analyses will subsequently be published. Trial registration number NCT03065088; Pre-results.

The trial commenced recruitment in March 2017. In August 2017, a total of 180 participants were included in the trial. We thank the ongoing support of participants, research staff, coordinators, data managers and other site staff who have been responsible for setting up the trial, recruiting participants and collecting data. Contributors All authors made substantial contribution to the concept and design of the study. KT drafted the manuscript, with input from BV and JLH. EB, DPF, CT and HHH provided input on behavioural change. SM, AZ, KA and API provided technical input on the eLiFE description. FBY and BG provided input on health economics. CB, MS and LC provided input on the background information about the project. ABM, JvA, NHJ and MP provided input on the medical assessment and screening of participants. SB, RB, BV, JLH and LC commented on the entire manuscript. KT, ASM, BV and JLH critically revised the manuscript with input from all coauthors. All authors approved the final version of the document. Funding The feasibility RCT is part of the EU funded project ’PreventIT' (2016– 2018, grant number 689238) responding to the Horizon 2020, Personalised Health and Care call PHC-21: Advancing active and healthy aging with ICT: Early risk detection and intervention. The PreventIT project focuses on a new behaviour change activity approach for young older adults (61–70 years of age) with an overall aim to shift focus from treatment of conditions and diseases to early prevention and to empower people to take care of their own health.
