About this study
Official title: Dietary Challenges in the Population of Nursing Homes' Residents in Slovenia
To obtain up-to-date data on nutritional status of older adults, a national dietary survey will be conducted in 2022/2023, providing data on the consumption of foods and enabling the assessment intakes of energy and specific nutrients. Participating subjects will be also screened for micronutrient status using blood biomarkers (focusing into vitamin D, folic acid, vitamin B12, and iron).
- Conditions
- Nutritional Status, Nutrient Deficiency, Micronutrient Deficiency, Vitamin D Deficiency, Vitamin B 12 Deficiency, Folic Acid Deficiency

Questions about this trial
What is this clinical trial studying?
An observational study of Nutritional Status and Nutrient Deficiency, run by Institute of Nutrition, Slovenia (Nutris) at 1 site in Slovenia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Assessment of protein intake (time frame: 1 year). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2026.
