Abstract in English Background: Physical and cognitive demands on military service are ever-increasing in the Finnish Defense Forces. The University of Helsinki and Center for Military medicine are conducting a pioneering research initiative known as the NutFinForce study. This innovative project aims to evaluate the impact of a digital delivered lifestyle intervention on the defense performance of Finnish conscripts.

Objective and Scope: The primary objective of the study is to enhance the physical and cognitive performance through targeted nutritional and lifestyle digital intervention. Equally we will assess the feasibility, acceptability, and cost-effectiveness of personalized digital health coaching and support for adopting healthier dietary and lifestyle habits. The aim is to foster long-term health benefits for public health and to improve national defense capability that isa a cumulative outcome for optimizing health of reserve.

Methodology: The intervention leverages a sophisticated digital platform that offers personalized guidance and support to participants. Special attention is paid to target group needs and military service as an environment in intervention design. Platform is accessible before, during, and after military service, ensuring opportunities for longitudinal and sustainable engagement and support. A large-scale implementation includes in selected brigades (each N=2000). Data collection will be conducted through the digital application platform used in the intervention.

Expected Outcomes: Key outcomes will include improvements in nutrition and eating patterns and perceived physical performance as swell as perceived cognitive sharpness/performance as a variable for outcome. The study will evaluate the cost-effectiveness of the intervention, providing important data for future policy and practice within the Finnish Defense Forces and NATO ally military forces.

Implications for Military Policy and Public Health: The findings from the NutFinForce study will have significant implications for military policy and practice. By demonstrating the benefits of digital health interventions that positively influence daily lifestyle behavior choices, the research could inform the development of future nutritional and lifestyle programs within the military. Moreover, the study's insights may have broader public health implications, highlighting the potential of digital health platforms to promote healthier behaviors and improve population health.

What researchers measure

Primary outcomes

  1. Eating habits and patterns

    Primary: Fruit, berry and vegetable consumption: Self-reported consumption frequency (times per day) and Breakfast frequency: Proportion of days with a recorded breakfast, based on meal photos in the application Secondary outcomes e.g. Group based analyses of eating contents will include averages and patterns e.g. Total Energy Intake, Fruit and Vegetables and Nutrient-Dense Foods Percentage of total Daily Energy Intake Energy-Dense Beverages like Sugar Sweetened Beverages (SSBs) and fruit juice Individual Food Groups and macronutrients Energy-Dense Nutrient-Poor (Ed-Np) Foods Diet Quality Score Rating

    Time frame: 24 moths

Secondary outcomes

  1. Nutirion component analyses

    Proportion of vegetable and fiber intake among users pre and post intervention

    Time frame: 24 moths

  2. Self-measured anthtopometrics

    There is an option to fill in the wights in kilograms in the application as well as high that can be used in calculations BMI, but it is not mandatory. This is not a weight reduction trial.

    Time frame: 24 moths

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2026 (actual). Primary completion is estimated for Dec 2028, 29 months after the start.

Of 100 non-industry observational studies under Feeding Behavior, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 62. This study's planned 29 months is above that.

Counting every sponsor, half of 101 studies reached it within 24 months; a quarter within 8 and three quarters within 62.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
