Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eight (8) week nutritional intervention with home-delivered meals. Three parallel intervention arms; two intervention groups, one control group.
Arm 1:
1/3 of participants allocated to intervention 1 (Arm 1).
Protein-enriched meal containing main dish, side dishes, salad/warm vegetables (20-25 g protein, meal size 350-380 g) and snack (10-15 g protein) and protein-rich bread (2 slices/day, 8-10 g protein) is offered at 7 days a week, 8 weeks. Participants fill daily a brief form about study meals, snack and bread; how much they ate meal components, was the taste and composition good, how many bread slices they consumed etc. One-day food diarys are also filled twice during the intervention (week 2 and 4) and three-day food diaries at week 8 .
Cold meals are delivered at home twice a week. Difference between Arm 1 and Arm 2 in protein intake is approx. + 30 g protein more in Arm 1.
Meals are prepared at Seniori Ateriat, which is a catering kitchen owned by Fazer Food Services in Finland. Meals are prepared with Cook&chill- method.

Arm 2:
1/3 of participants allocated to intervention 2 (Arm 2).
Normal home-meal with main dish, side dishes, salad/warm vegetables (17-19 g protein, meal size 350-380 g) is offered at 7 days a week, 8 weeks. Participants fill daily a brief form about study meals; how much they ate meal components, was the taste and composition good etc. One-day food diarys are also filled twice during the intervention (week 2 and 4) and three-day food diaries at week 8. Cold meals are delivered at home twice a week.
Meals are prepared at Seniori Ateriat, which is a catering kitchen owned by Fazer Food Services in Finland. Meals are prepared with Cook&chill- method.

Arm 3:
1/3 of participants allocated to control group (Arm 3).
Control group continues eating as usual (their normal own diet) for 8 weeks. No home-delivered meals during intervention.One-day food diarys are filled twice during the 8 weeks (week 2 and 4) and three-day food diaries at week 8 .

Comparator / control treatment
Control group continues eating as before. No home-delivered meals during intervention. One-day food diarys are filled twice during the 8 weeks (week 2 and 4) and three-day food diaries at week 8 .

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants are randomly allocated one by one to the intervention 1 or 2 (Arm 1 and 2) or the control group (Arm 3) according to a computer-generated, blocked randomization list. If there are two participants from the same household, they will be rndomized to same group. A person unrelated to the study carries out the randomization.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software
Masking / blinding
Open (masking not used)

Efficacy
Statistical methods / analysis
Sample size was calculated based on expected change in protein intake in the intervention groups from 1,0 g/kgBW/d (SD 0,3) to 1,2 g/kgBW/d. Calculation based on Cohens effect size (f) in Variance analysis which was set on 0.25 - 0.30. Assumption was that protein intake will not chanhe in control group. Calculated sample size is 105 (35 per group) ß=0.85 and a=0.05. Sample size was estimated using G*Power (version 3.1.9.2) software.
SPSS version 25.0 (SPSS, Inc., Chicago, IL) and STATA 14.1 are used in statistical analyses.
The results are presented as means with SDs or as percentages, with 95% confidence intervals for the major outcomes. Statistical differences between the groups are determined by t-tests, Mann Whitney U-test, Chi Square test or Fisher´s exact test.
The main outcome measures are subjected to an analysis of covariance (ANCOVA) with appropriate covariates.

Summary
Brief summary
The purpose of the study is to investigate the effictiveness of home-delivered meals on older people`s nutrien intake, physical performance and activity and health-related quality of life. The study design is randomized controlled trial and the home-delivered meal intervention lasts for eight weeks. The odjective is to increase nutrient intake, especially protein, and to improve physical performance, activity and quality of life.
