Abstract
Background: A healthy diet is a key determinant of an individual's health status and is closely related to mental health and quality of life (QoL); however, the exact nature of the relationship is unknown. This study hypothesized that a higher diet quality score is associated with a lower observance of symptoms of depression and anxiety and a higher QoL. Methods: This study evaluated 1,295 adults (521 men; 774 women) aged 19-64 years, who participated in the 2014-2015 National Fitness Award Project. Diet quality was measured by the recommended food score (RFS), and mental health and QoL were assessed by the beck depression inventory (BDI), beck anxiety inventory (BAI), and the World Health Organization QoL-Brief (WHOQoL-BREF). Results: After adjusting for covariates, the individuals with depression had a significantly lower RFS value compared to those without depression, and the group with a QoL score above the median had a higher RFS value than the group with a QoL score below the median. These trends occurred in both men and women. Subjects in the highest tertile of RFS showed a lower odds of depression (OR = 0.51, 95% CI = 0.32-0.81, p-trend = 0.0043) and a QoL score below the median (OR = 0.40, 95% CI = 0.30-0.54, p-trend < 0.0001) compared with those in the lowest tertile. The RFS was not associated with anxiety. Conclusions: Our data suggest that higher diet quality may be associated with lower depressive symptoms and a better QoL in Korean adults.

This study was performed within the framework of a cross-sectional survey designed to develop criteria referencing health-related fitness standards for the National Fitness Award Project [31]. The National Fitness Award project is a large-scale national project currently managed by 21 centers. The Korea Institute of Sports Science has been conducting this project since 2012, with the support of the Ministry of Culture, Sports, and Tourism to promote health by exercise, physical, and sporting activities in daily life. Adults and seniors have been recruited since 2014, and the present study was based on the 2014–2015 National Fitness Award Project for participants aged 19–64 years (n = 2,280). We excluded pregnant subjects (n = 1); those without data for the RFS (n = 973); those without data on the beck depression inventory (BDI), beck anxiety inventory (BAI), World Health Organization Quality of Life–Brief (WHOQoL–BREF), or all three indicators (n = 8); and those lacking background information, such as age, gender, and body mass index (BMI) (n = 3). Finally, 1,295 subjects were eligible for further analysis and stratified by gender. Ethical approval of this retrospective study was given by the Institutional Review Board (IRB) of the Korea Institute of Sport Science (KISS-201504_EFS-002-01), and Ewha Womans University (120–2, August 2018), and all subjects provided their written informed consent to participate in the study.
