Objective: This study aimed to investigate the association between adherence score of dietary guidelines and risk of metabolic syndrome (MetS).
Methods: Since 2011, the Seoul Metabolic Syndrome Management (SMESY) program was instituted with the aim of reducing the prevalence of MetS among the citizens. Among 200,916 people who participated and were followed for a year in the SMESY program in 2015, 54,385 participants aged 20-64 who were not on medication for diabetes, hypertension, and dyslipidemia were selected for analysis. They were classified into 3 groups according to the number of MetS risk factors (≥3, 1-2, and none) at baseline. Anthropometric data and biochemical indices from blood samples were collected before and after the program at the public health centers. Participants also completed questionnaires on health-related behaviors including adherence to 10 dietary guidelines. These guidelines included balanced dietary behaviors, consumption of various fruits, vegetables and dairy products, and eating less sodium and fat.
Results: Each MetS risk factor improved significantly after the program among subjects with MetS. At the end of the program, the number of MetS risk factors was significantly lower (average 2.7) among the subjects compared to baseline MetS risk factors (average 3.4). More participants adhered to the dietary guidelines after participation; especially adherence to a low-salt diet among subjects with MetS. The prevalence of MetS among subjects with higher adherence score was significantly lower than those with lower adherence score after a year. Among subjects with 1-2 MetS risk factors, hazard ratios (HR) of MetS were significantly lower in the cases with positively changed adherence score of the dietary guidelines compared to those negatively changed. Also increased adherence score was associated with 25% lower risk of MetS (HR=0.75; 95% CI=0.70-0.81) compared to decreased score.
Conclusion: This study showed that higher adherence score of dietary guidelines in the SMESY program was inversely associated with MetS. Further researches are required to investigate the associations between dietary guidelines and various metabolic diseases.
