Investigation of nutrition literacy and quality of life in adults

Abstract

This study aimed to investigate the relationship between nutrition literacy (NL) score and quality of life (QoL) score for adults aged 19-64. The study included 430 adults. Data were collected through a questionnaire, the Evaluation Instrument of Nutrition Literacy on Adults (EINLA), and the European Health Impact Scale (EUROHIS). Sociodemographic data, anthropometric measurements, and biochemical parameters of adults were collected. The data were interpreted by T-test, One-Way Analysis of Variance (ANOVA), Chi-squared Test, and Pearson correlation analysis through the SPSS 21.0 IBM package program. 59.8% of participants had sufficient NL. Participants with enough EINLA scores had significantly lower body weight, body fat mass, fasting blood glucose, and triglyceride. The mean EUROHIS scores of participants with bachelor/postgraduate degrees were considerably higher than those with primary school graduates. A negative correlation was found between the age and BMI of the participants and their NL scores. It has been shown that there is a very weak positive correlation between the NL score and the QoL level of adults. As the NL level of adults increases, the QoL is expected to improve. According to the findings obtained from the research, it is necessary to increase the community's level of NL.
