Introduction: This cross-sectional study was performed to investigate nutrition literacy of adults living in the city center of Sivas and the relationship between nutrition literacy and quality of life.
Material and Methods: The study sample consisted of 384 people. Of the people residing in the houses located in 63 neighborhoods in the city center, those who met the inclusion criteria were included in the study. The houses were selected using the simple random sampling method. The participation rate was 95.5%. Data were collected with the Personal Information Form, Evaluation Instrument of Nutrition Literacy on Adults (EINLA), and the World Health Organization Quality of Life Scale (WHOQOL-BREF-TR). To analyze the data, in addition to descriptive statistical methods (number, percentages, means etc.), Chi-square, Pearson correlation analysis, the test for the significance of the difference between two means, one-way analysis of variance and Kruskal Wallis test were used. The error rate was p <0.05.
Results: Nutrition literacy levels of 79.8% of the participants were determined to be adequate. However, when the sub-scales were analyzed, it was determined that 33.5% of the participantsâ€™ knowledge on general nutrition was inadequate, 20.2% had difficulty understanding and interpreting what they read, 12.8% were not knowledgeable enough about food groups, 88.2% lacked knowledge about the daily serving sizes and 90.3% lacked knowledge on numerical literacy or reading food labels. A significant correlation was determined between the mean nutrition literacy scores and variables such as gender, education and profession (p <0.05). A positive, significant but weak correlation was found between the mean nutrition literacy scores and the mean scores for the physical, psychological and social domains of quality of life (p <0.05).
Conclusion: In the city center of Sivas, nutrition literacy rate of the adult population was 79.8%. The mean scores the participants obtained specially from the daily serving sizes, food label reading and numerical literacy domains were inadequate. If they can obtain higher scores from those domains, this will enhance their quality of life in physical, psychological and social domains.
