About this study
Official title: Assessing Weight Bias Among Turkish Dietitians: Determinants and Impact on Professional Practice
The objective of this study was to examine weight bias among Turkish dietitians. and to investigate the effect of the patient's weight status on the dietitian's assessment and dietetic practice.
Read the detailed description
The dietitians were randomly assigned to an online case study with lactose intolerance, with all patient information identical except for the patient's weight and photograph. In one case there was a photograph of a woman with obesity and in the other a woman of normal weight. The objective of the case study was to evaluate how the body weight of a patient who consulted a dietitian for a reason unrelated to the body weight affected professional practices.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Picture belong to a patient with obesity | Dietitians were randomly assigned to a case study via SurveyMonkey. All the information (demographics, biochemical parameters and diet history physical activity level) about the cases was the same, only their weight and, therefore, their photographs were different. In this case there was a photograph of a woman with obesity | |
| Picture belong to a patient with normal-weight | Dietitians were randomly assigned to a case study via SurveyMonkey. All the information (demographics, biochemical parameters and diet history physical activity level) about the cases was the same, only their weight and, therefore, their photographs were different. In this case there was a photograph of a woman with normal weight. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Differences between dietitians' lifestyle recommendations among groups.
Dietitians' recommendations lifestyle recommendations (such as dietary intake of energy and macronutrients) were assessed using a 5-point Likert-type scale (1; should be greatly reduced, 5; should be greatly increased).
Measured: Baseline
Secondary outcomes (3)
Differences between the biochemical status rated by dietitians between groups
Dietitians rated the biochemical status of the case with a 5-point Likert type scale (1; very good, 5; very poor).
Measured: Baseline
Differences between the diet quality rated by dietitians between groups
Dietitians rated the diet quality of the case with a 5-point Likert type scale (1; very good, 5; very poor).
Measured: Baseline
Differences between dietatians' expectations regarding the patient's adherence to the diet between groups
Dietatians' expectations regarding the patient's adherence to the diet were assessed using the statements "the patient is willing to be treated", "the patient is expected to comply with the treatment recommendations", "the patient will be successful in making dietary changes", "the patient will be able to sustain recommendations", "the patient understood treatment recommendations". A 5-point Likert type scale (1; strongly disagree, 5; strongly agree) was used to rate these statements.
Measured: Baseline
