Recruitment
Older adults residing in a selected elderly care institution will be screened using the Mini Nutrition Assessment tool (MNA). Older adults who have been identified with a MNA score equal to or less than 11 and satisfied all the other eligibility criteria mentioned above, will be informed about the study both verbally and in writing, in their native language. Information provided will include the aims of the study, participants’ responsibilities, follow-up visits and procedures, potential individual and societal benefits, risks involved, and the ability to withdraw from the study at any time, without any consequences. In addition, opportunities will be provided during this process for any clarification required by the study participants to ensure maximal understanding. Interested participants will be recruited voluntarily. After the written informed consent has been obtained by the co-investigator (PW), participants will be randomly assigned to receive either the oral nutrition supplement or the placebo for 12 weeks.
