Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the study participants (n = 102) are randomized into two groups; to an intervention group and to a control group. The participants are older women of 70 years or older, who have mobility limitations. After the randomization taking place after baseline measurements, on bases of the intervention participants' protein intake analyzed from their food records, they will receive 1-2 snack products daily for three months and advise by trained nutritionist on how to use them as part of daily diet. The milk-based snack products are protein rich and contain at least 1 g of milk fat globule membrane that has in previous trials improved physical performance in humans and animals, and 15-30 g of protein (depending on the baseline protein intake of the participant). The intervention participants are advised to time the consumption of the snack products in close proximity with daily physical activity. Both groups (intervention, control) are taught to perform short daily exercise routine containing five exercises planned to improve gate speed and advised to perform the routine independently daily. They will also receive written instruction of the routine. The materials will be readily available. We will use materials provided by the Age institute in Finland. The daily exercise routine will last about 15 minutes to perform. The examples of the daily routine can be found following this link: https://www.voimaavanhuuteen.fi/content/uploads/2016/04/k%C3%A4vely_kevyemm%C3%A4ksi.pdf. We will monitor the adherence to the exercise routine and research product with self-report log, and with product return. We will keep in contact with the participants regularly via phone during the intervention.
Due to the pandemic, the nutritionist will keep in contact with the intervention participants only by phone or computer to give advise remotely to the participants on the consumption of the products. They will also receive written advise on the timing on the consumption of the products. The participants are advised to replace a normal snack or dessert in their diet with the snack product provided by the study in order to keep the intervention weight neutral. However, in case of a participant has low BMI (egual or less than 23 kg/m2), is losing weight involuntarily or has a poor appetite, they will be encouraged to consume the snack products in top of their ordinary daily diet.

The interventionist (nutritionist) will go through training prior to the start of the trial. The snack products will be delivered to the homes of the participants by a delivery service with regular intervals.

Comparator / control treatment
The control group will receive no snack products. However, the control and intervention groups will be taught to perform the same short daily exercise routine containing five exercises planned to improve gate speed and advised to perform the routine independently daily. They will also receive written instruction of the routine. The control group will additionally receive a brochure of healthy nutrition and take part of all the measurements. The brochure of healthy nutrition is already available resource found following the link: https://syohyvaa.fi/wp-content/uploads/2016/04/Selkokielinen-Sy%C3%B6-hyv%C3%A4%C3%A4-esite.pdf

Summary
Brief summary
We investigate the effect of protein and MFGM containing snack products on physical performance of older women of 70 years or over who at baseline have mobility limitations
in 12 week RCT, Participants in the IG will consume daily 1-2 snack product that contains protein and MFGM containing 15-30 g of protein and at least 1 g MFGM. The main outcome of the study is physical performance measured with 5 times chair stand test. We hypothesize that the combined effect of protein and MFGM may improve physical performance of older women who have mild mobility limitations .
