This study will evaluate the effect of a brief intervention on anthropometric and metabolic changes in overweight women with low health literacy. The total number of samples was determined as 88. It was decided to recruit a total of 124 people, 62 people in each group, with a 40% loss in the groups. Brief intervention interviews will be conducted with the intervention group. Brief intervention interviews will take an average of 20-30 minutes and four times. The control group will not be intervened except for the first and last evaluations.

This study will evaluate the effect of a brief intervention on anthropometric and metabolic changes in overweight women with low health literacy. The total number of samples was determined as 88, 44 in each of the intervention and control groups. It was decided to recruit a total of 124 people, 62 people in each group, with a 40% loss in the groups. Randomization will be performed after obtaining consent from the participants who meet the eligibility and exclusion criteria. The sampled individuals will be assigned to the Intervention and Control groups according to the block randomization method. Brief intervention interviews will be conducted with the intervention group. It was determined as the first evaluation and the follow-ups on the 1st day, 15th day, 1st month, 3rd month, and the last evaluation (6th month). Brief interventions, 5A for those who are ready to change their behavior (Ask, Advise, Assess, Assist, Arrange); those who are not ready to change their behavior 5R (Relevance, Risks, Rewards, Roadblocks, Repetition) model will be used. At the end of brief interventions applied to overweight women with low health literacy for 20-30 minutes, a total of four times; weight change, waist circumference change, blood pressure change, blood glucose change, blood lipid change, diet, and exercise behaviors will be evaluated. The control group will not be intervened except for the first and last evaluations.

For each group, 21 blocks were created by generating random numbers in Excel by a person other than the researcher and assigned to groups A and B. The assignment of the intervention and control groups was made by drawing lots. Index cards prepared for two primary healthcare organizations by block randomization by the researcher who did not participate in the clinical part of the study will be placed in closed opaque envelopes and their sequence numbers will be written on the envelopes. The research data will be entered into the computer database by the researcher as coded as A and B. Statistical analyses will be performed by the researcher who did not participate in the data collection phase according to this code. The research report will also be written in coded form. Research participants and statistical evaluators were planned to be blind to group assignment, single-blind, and statistician blind.
