Tidsramme |
|---|---|---|
|
Composite Dietary Antioxidant Index (CDAI)
Tidsramme: Baseline
|
The Composite Dietary Antioxidant Index (CDAI) will be calculated to evaluate the total and synergistic effect of dietary antioxidants.
It is based on the standardized daily intake of six main antioxidant components: Vitamin A, Vitamin C, Vitamin E, Magnesium, Selenium, and Zinc.
Nutrient data will be obtained from food consumption records using the BeBiS 9 nutritional software.
For each antioxidant nutrient, a unitless Z-score will be calculated by subtracting the population's mean intake from the individual's intake and dividing by the standard deviation.

|
|
The Dietary Antioxidant Index
Tidsramme: Baseline
|
The Dietary Antioxidant Index (DAI) will be calculated based on the daily antioxidant intake obtained from the participants' food frequency questionnaire data.
The main dietary antioxidant components (Vitamin C, Vitamin E, $\beta$-carotene, flavonoids, and other polyphenols) will be quantitatively determined using the BeBiS 9 nutritional software.
For each antioxidant component, the obtained values will be standardized into a Z-score by subtracting the mean intake of the study population from the individual's intake and dividing by the standard deviation.
The individual's final DAI score will then be calculated by summing the Z-scores of all these components.

Nutritional Assessment - Nutritional Risk Screening 2002 (NRS-2002)
Tidsramme: Baseline
|
The nutritional risk of the participants will be evaluated using the Nutritional Risk Screening 2002 (NRS-2002) tool.
The NRS-2002 assesses impaired nutritional status and disease severity.
The total score ranges from 0 to 7. A total score of 3 or higher indicates that the patient is at nutritional risk, while a score less than 3 indicates no immediate nutritional risk.
The assessment will be administered by the researcher at the beginning of the study.
|
Baseline
|
|
Nutritional Assessment - Malnutrition Universal Screening Tool (MUST)
Tidsramme: Baseline
|
The nutritional risk of the participants will be evaluated using the Malnutrition Universal Screening Tool (MUST).
MUST is a validated screening tool used to identify adults who are malnourished or at risk of malnutrition.
The score is calculated based on three parameters: current body mass index (BMI), unintentional weight loss, and the effect of acute disease.
The total score ranges from 0 to 6.
A score of 0 indicates low risk, a score of 1 indicates medium risk, and a score of 2 or higher indicates a high risk of malnutrition.
The assessment will be administered by the researcher at the beginning of the study.
