About this study
Official title: Investigation of Sustainable Eating Behaviors and Diet Quality in Adults
The goal of this observational study is to evaluate the sustainable nutrition behaviors (e.g. not wasting food, consuming organic food) and diet quality of university staff. The main questions it aims to answer are:
- What is the diet quality of the participants?
- Do participants with higher diet quality have better sustainable eating behaviors?
Read the detailed description
Sustainable diets are diets with low environmental impacts that contribute to food and nutritional security and healthy living for present and future generations. They are recognized as protective of ecosystems, culturally acceptable, accessible, economically fair and affordable, nutritionally adequate, safe and healthy diets. Sustainable healthy diets ensure optimal growth and development of all individuals, support functionality across all life stages for current and future generations, contribute to the prevention of all forms of malnutrition, reduce the risk of diet-related non-communicable diseases and support the protection of biodiversity and planetary health. Recently, the need to promote nutritious and safe sustainable diets with low environmental impact has been emphasized. Diets based mostly on plant-based foods, such as the Mediterranean diet and the DASH diet, are recognized as sustainable eating models. The aim of this study is to evaluate the sustainable eating behaviors and diet quality based on food consumption of academic and administrative staff working at the university and to determine the relationship between them.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Observational TestsBehavioural
The Sustainable and Healthy Eating Behaviors Scale will be used to assess sustainable eating behaviors, one-day food consumption records will be collected with the 24-hour Dietary Recall method, the International Diet Quality Index and EAT-Lancet Diet Score will be used to assess diet quality, and body weight, height, waist circumference and neck circumference will be measured to determine nutritional status.
| Study group | Role | What they receive |
|---|---|---|
| Adults | Academic and administrative staff working at Tarsus University Receives: Behavioral: Observational Tests |
What is being measured
The primary outcome is the main question the study is designed to answer.
24-hour Dietary Recall
To assess the diet quality of the participants. It will be evaluated using the Nutrition Information System (BeBiS). In the 24-hour Dietary Recall, the foods consumed at all meals, the contents and quantities of the meals will be questioned. Standard recipes will be used for foods or meals consumed outside the home.
Measured: 1 year
Sustainable and Healthy Eating Behaviors Scale
It will be used to assess participants' sustainable nutrition behaviors. The Turkish version of the scale consists of 7 factors and 32 Likert-type questions, including Quality Marks (Local and Organic), Seasonal Foods and Avoiding Food Waste, Animal Health, Reducing Meat Consumption, Healthy and Balanced Nutrition, Local Food and Low Fat. Respondents are asked to rate the questions as never, very rarely, rarely, sometimes, often, very often and always. Never=1 point and Always=7 points. There is no intercept value in the evaluation, a high score indicates an increase in sustainable and healthy eating behavior.
Measured: 1 year
International Diet Quality Index
To be used to assess diet quality. This index was developed to assess and compare diet quality across countries. It assesses four components of the diet: variety, adequacy, moderation and overall balance. The sum of the scores in these four main categories determines the total score for the index. The total score ranges from 0-100 (0= lowest diet quality, 100= highest diet quality). According to the index total score, a score of 0- ≤45 points is classified as poor diet quality, >55- ≤60 points as moderate diet quality, and >75 points as high diet quality.
Measured: 1 year
Body weight in kilograms
Body weight measurement will be made with a weighing device sensitive to 0.5 kg.
Measured: 1 year
Height in meters
A stadiometer will be used to measure height and measurements will be recorded with an accuracy of 0.1 cm. The measurement will be made without shoes, feet together, head in the Frankfurt plane, and head, back, hips, calves and heels in the same plane.
Measured: 1 year
Waist circumference in centimeters
Waist circumference will be measured at the midpoint between the lowest rib and the iliac crest using a non-stretchable tape measure. The measurement will be repeated twice and averaged.
Measured: 1 year
Neck circumference in centimeters
Neck circumference will be measured in the middle of the neck, between the mid-cervical spine and mid-anterior neck, using a non-stretchable tape measure while the participants are standing upright, and recorded with an accuracy of 0.1 cm. In men with a laryngeal protrusion, it will be measured just below the protrusion.
Measured: 1 year
Secondary outcomes (1)
EAT-Lancet Diet Score
It includes 14 main recommendations. For different food groups, a score of "1" is given if the person consumed the specified amount and a score of "0" if the person did not consume the specified amount. The maximum score for this diet score is 14.
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
An observational study of Nutrition, Healthy, run by Ankara University at 1 site in Turkey (Türkiye).
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 2 inclusion and 3 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 12 Mar 2025. 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 Turkey (Türkiye). 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?
24-hour Dietary Recall (time frame: 1 year). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06100666, which also lists 7 linked publications.
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 12 Mar 2025.
