- ACRONYMPROMISS Pilot study 1
- hypothesisIn this pilot study among community-dwelling older adults with lower protein intake (< 1.0 g/kg/body weight), we hypothesize that personalized dietary advice will increase protein intake in close proximity of usual physical activity.
- Healt Condition(s) or Problem(s) studiedProtein energy malnutrition, Malnutrition, Protein, Energy
- Inclusion criteria- Age ≥ 70 years
- Community-dwelling

- InterventionsThe pilot study is a 3-week, parallel, randomized controlled trial with three intervention arms. Community-dwelling older adults will be randomly assigned to one of the three intervention arms, stratified by sex:

Group 1: Participants will be provided with selected protein rich food products;

Group 2: Participants will be provided with selected protein rich food products and personalized advice to link protein rich food product intake to usual activity;

Group 3: Participants will be provided with selected protein rich food products and personalized advice to link timing physical activity to protein rich food product intake.
- Primary outcomeThe main study parameters of this pilot experiment are:

1) the feasibility of a) the consumption of protein rich food products; b) the consumption of protein rich food products in close proximity of usual physical activity;

2) participantsí appreciation regarding the provided protein rich food products.
- Secondary outcomeThe secondary study parameters of this pilot experiment are change in:

- Appetite
- Body weight
- TimepointsThe pilot experiment consist of 5 timepoints:

1) (three weeks prior to study baseline): Telephone screening;
2) (two and a half weeks prior to study baseline): Home visit;
3) (study baseline): Clinic visit;
4) (one week after study baseline): Telephone interview;
5) (end of study): Clinic visit.

- Brief summaryRationale: With the European population growing older, the challenge is to keep an increasing number of seniors across all European countries healthy and active. In Europe, between 13.5 % and 29.7 % of older adults living at home are (at risk of) protein energy malnutrition (PEM), which results in serious health problems. This pilot study will be conducted to optimize the design and intervention strategies for the long term prevention trial which is part of the Horizon 2020 project PRevention Of Malnutrition In older Senior Subjects (PROMISS).

Objective: In this pilot study among 45 community-dwelling older adults aged ≥ 70 years with lower protein intake (< 1.0 g/kg/body weight), we will investigate: 1) Which strategy is most feasible to consume provided protein rich food products use; and 2) which strategy is most feasible to consume provided protein rich food products use in close proximity of usual physical activity by a) providing protein rich food products only; b) providing protein rich food products and to link timing protein rich food product intake to usual activity; or c) providing protein rich food products and to link timing of physical activity to protein rich food product intake; and 3) How are protein rich food products appreciated by community-dwelling older adults with lower protein intake.

Study design: A pilot study: randomized controlled trial with the duration of three weeks.

Intervention: This pilot study consists of three groups; the first group will be instructed to comply with the dietary strategies (i.e. consume provided protein rich food products); the second group will be instructed to comply with the dietary strategies and in addition link their daily food intake pattern to their daily physical activity pattern (for example, consume a specific protein rich food product after walking the dog instead of coffee); the third group will be instructed to optimize their physical activity pattern to their daily dietary pattern (for example, postpone walking to the dog just before consuming a specific protein rich food product). Participants from all groups will receive protein rich food products and personalized advice, taken into account participants food preferences, usual food intake and body mass index (BMI) in order to prevent food waste and under- or overfeeding.

Main study parameters/endpoints: The main study parameters of this pilot study are the feasibility of dietary and physical activity strategies, and the preferences of both the strategies and the provided protein rich food products of community-dwelling older adults.
