Plain English Summary

Background and study aims
Ageing is commonly associated with a decline in clinical and functional status and perceived well-being. This decline is associated with multi-morbidity, defined by the coexistence of two or more chronic disease conditions. Living with multi-morbidity impairs an individual’s quality of life, health span and lifespan.
The study aims are to assess the effect of a personalised, digitally delivered lifestyle intervention on clinical status (waist circumference), functional status (hand grip strength) and perceived well-being (WHO 5 well-being index) after 1 year. The study will also evaluate the effect of the lifestyle intervention on the onset and severity of multimorbidity and death after 3 years.
The KORA Digital-Fit study is part of the STAGE project. STAGE is a European Research and Innovation project studying healthy ageing and multi-morbidity using a life-course approach (https://stage-healthyageing.eu).

Who can participate?
Men and women aged 50-79 years from the population-based KORA cohort (Cooperative Health Research in the Region of Augsburg) who are part of the baseline surveys will be invited to participate.

What does the study involve?
Participants will be assigned to the intervention or standard of care group according to personal preference and eligibility. The digital intervention will provide personalised digital health coaching aimed at managing and preventing chronic conditions like obesity, type 2 diabetes, and cardiovascular diseases. Both the intervention group and matched participants of the standard of care group will undergo an end-of-study assessment after 1 year, as well as a telephone interview after 3 years.

What are the possible benefits and risks of participating?
The intervention group will be informed about individual lifelong health. The findings are beneficial as they will be used to develop qualitative prevention concepts for the ageing population.

Where is the study run from?
KORA Study Center (Germany)

When is the study starting and how long is it expected to run for?
January 2024 to December 2029

Who is funding the study?
The KORA study was initiated and financed by the Helmholtz Zentrum München – German Research Center for Environmental Health, which is funded by the German Federal Ministry of Education and Research (BMBF) and by the State of Bavaria. Data collection in the KORA study is done in cooperation with the University Hospital of Augsburg. The KORA Digital-Fit study is part of the STAGE project. STAGE has received funding from the European Union’s Horizon Europe Research and Innovation Programme under grant agreement nº 101137146. UK participants in Horizon Europe Project STAGE are supported by UKRI grant numbers 10112787 (Beta Technology), 10099041 (University of Bristol) and 10109957 (Imperial College London).

ConditionStay healthy through ageing and prevention of multimorbidity
InterventionA digitally delivered lifestyle intervention based on coaching regarding a healthy lifestyle with the overarching aim of ameliorating waist circumference, increasing muscle strength and perceived well-being over 1 year compared to standard of care.

Participants will be assigned to the intervention or standard of care group according to personal preference and eligibility. The digital intervention will provide personalised digital health coaching aimed at managing and preventing chronic conditions like obesity, type 2 diabetes and cardiovascular diseases. Both the intervention group and matched participants of the standard of care group will undergo an end-of-study assessment after 1 year, as well as a telephone interview after 3 years.
Intervention typeBehavioural
Primary outcome measure1. Waist circumference is measured using measuring tape at baseline and 1 year
2. Hand grip strength is measured using a hand dynamometer at baseline and 1 year
3. Well-being measured using the WHO-5 well-being index (self-report questionnaire) at baseline and 1 year
Secondary outcome measures1. Multi-morbidity is measured by self-report at 3 years
2. Mortality is measured from record data at 3 years
