Brief 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).
Interventions
OTHERDiagnostic Tests
Assessment of socio-demographic parameters, anthropometric and body composition parameters, food intake (dietary recalls, food propensity questionnaire) and nutritional status (blood biomarkers)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of energy intake | 1 year | epidemiology of energy intake will be investigated from food records \[kJ/day\] |
| Assessment of protein intake | 1 year | epidemiology of protein intake will be investigated from food records \[g/day\] |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of inadequate folate status | 1 year | epidemiology of folate status will be investigated using serum folate concentration |
| Assessment of inadequate vitamin B12 status | 1 year | epidemiology of vitamin B12 status will be investigated using serum vitamin B12 concentration |
| Assessment of inadequate vitamin D status | 1 year | epidemiology of vitamin D status will be investigated using serum 25-OH-vitamin D concentration |
| Assessment of inadequate iron status | 1 year | epidemiology of iron status will be investigated using serum ferritin concentration |
| Assessment of anemia | 1 year | epidemiology of anemia will be investigated using serum haemoglobin concentration |
Other
| Measure | Time frame | Description |
|---|---|---|
| Body mass index | 1 year | Weight and height will be combined to report BMI in kg/m\^2 and providing insights into prevalence of overweight/obesity |
| Nutritional intakes | 1 year | epidemiology of dietary intake of nutrients and fibre will be investigated from food records \[g/day\] |
| Prevalence of sarcopenia | 1 years | 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) |
