About this study

The study included 2,705 individuals aged 19-65 working in various occupations. Data were collected using a demographic structure survey and the Behaviors Scale Towards Sustainable Nutrition (BSSN). A food consumption frequency survey was administered to calculate the EAT-Lancet Index. Occupations were classified into five groups according to the International Standard Classification of Occupations (ISCO)-88: Groups 1-2, 3-4, 5-8, 6-7, and 9-10. Additionally, occupational skill levels were categorized into four levels (1 being the lowest and 4 the highest) based on ISCO-88. Statistical analysis was performed using SPSS version 24.

Treatment and study plan

Primary outcomes

  1. EAT-Lancet Index score

    Time frame: Baseline

    Food components in the EAT-Lancet diet are classified as "restricted foods" and "emphasized foods." Restricted foods include pork, beef, lamb, poultry, potatoes, eggs, and added sugar. Emphasized foods include fruits, vegetables, legumes, unsaturated fats, fish, whole grains, and nuts. Dietary intake is assessed based on the reported amounts in grams per day of uncooked weight, aligning with the target intake levels specified in the EAT-Lancet diet.

    The index consists of 14 food components, with each scored from 0 to 3. A score of 0 indicates low adherence to the target for a given food component, while a score of 3 reflects high adherence. The total index score ranges from 0 (no adherence) to 42 (perfect adherence, calculated as 14 components × 3 points). The food consumption frequency method was used to calculate the EAT-Lancet Index.

Secondary outcomes

  1. Behaviors scale towards sustainable nutrition (BSSN) score

    Time frame: Baseline

    The scale was developed to measure sustainable consumption behaviors. It consists of 11 questions in total and uses a 7-point Likert format. The scale is divided into two subsections that assess individuals' nutrition and purchasing preferences. A minimum of 0 and a maximum of 66 points are obtained from the scale. Higher scores on the scale indicate stronger sustainable food consumption behaviors.

  2. Sociodemographic characteristics

    Time frame: Baseline

    Sociodemographic characteristics will be assessed using a structured questionnaire developed by the researchers. The questionnaire will include items measuring age, gender, education level, and income status. The results will be presented as numbers and percentages for each characteristic.

  3. Body Mass Index (BMI)

    Time frame: Baseline

    Kilograms per square meter (kg/m2)

  4. Body weight

    Time frame: Baseline

    Body weight in kg

  5. Height

    Time frame: Baseline

    Height in cm
