Study summary

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).

What researchers measure

Primary outcomes

  1. Assessment of protein intake

    epidemiology of protein intake will be investigated from food records \[g/day\]

    Time frame: 1 year

  2. Assessment of energy intake

    epidemiology of energy intake will be investigated from food records \[kJ/day\]

    Time frame: 1 year

Secondary outcomes

  1. Assessment of inadequate vitamin D status

    epidemiology of vitamin D status will be investigated using serum 25-OH-vitamin D concentration

    Time frame: 1 year

  2. Assessment of inadequate folate status

    epidemiology of folate status will be investigated using serum folate concentration

    Time frame: 1 year

  3. Assessment of inadequate vitamin B12 status

    epidemiology of vitamin B12 status will be investigated using serum vitamin B12 concentration

    Time frame: 1 year

  4. Assessment of inadequate iron status

    epidemiology of iron status will be investigated using serum ferritin concentration

    Time frame: 1 year

  5. Assessment of anemia

    epidemiology of anemia will be investigated using serum haemoglobin concentration

    Time frame: 1 year

Other outcomes

  1. Nutritional intakes

    epidemiology of dietary intake of nutrients and fibre will be investigated from food records \[g/day\]

    Time frame: 1 year

  2. Body mass index

    Weight and height will be combined to report BMI in kg/m\^2 and providing insights into prevalence of overweight/obesity

    Time frame: 1 year

  3. Prevalence of sarcopenia

    epidemiology of sarcopenia will be investigated using EWGSOP2 (European Working Group on Sarcopenia in Older People 2) criteria and estimated ASM (apendicular skeletal muscle mass)

    Time frame: 1 years

Ran from May 2022 to primary completion in Feb 2023, 8 months.

Since we started tracking on Sep 25, 2026, the dates moved once, on Nov 2, 2026: primary completion Sep 2023 → Feb 2023 and completion Dec 2023 → Feb 2023.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
