Abstract:
BACKGROUND/OBJECTIVES:Metabolic syndrome is closely associated with lifestyle factors, including diet and nutritional intake. Modern trends show a shift in food consumption from healthy home-cooked meals to processed and instant foods. Therefore, this study analyzed the association between ultra-processed food intake and the development of metabolic syndrome in Korean adults based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2013–2018.
SUBJECTS/METHODS:The subjects of this study were 17,414 adults aged 19–80 years who participated in the 6th–7th KNHANES. Processed food was classified into four categories, NOVA1 to NOVA4, using 24-h recall data. The higher the NOVA category, the more processed the food. Statistical analysis was conducted using logistic regression to investigate the prevalence of metabolic syndrome according to the consumption of ultra-processed foods.
RESULTS:Among the diagnostic criteria for metabolic syndrome, hypertension (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.62–0.85; Q4 vs. Q1, P-trend < 0.001) and high triglycerides (OR, 0.83; 95% CI, 0.72–0.94; Q4 vs. Q1, P-trend < 0.001) showed a correlation with the percentages of energy consumed from ultra-processed foods. The OR for metabolic syndrome, according to the percentages of energy consumed from ultra-processed foods, is shown only for men. The OR showed that the percentages of energy consumed from ultraprocessed foods were associated with increased metabolic syndrome.
CONCLUSIONS:This study suggests that consumption of ultra-processed foods raises the risk of metabolic syndrome especially among men. To prevent metabolic syndrome, it is necessary to prepare appropriate dietary guidelines for Korean adults.
