摘要

Background

With the increasing burden of metabolic syndrome, it is crucial to focus on lifestyle factors to reduce the risk of metabolic syndrome.

Objectives

This study aims to quantify the associations between dietary diversity and the risk of metabolic syndrome among the Japanese population.

Methods

This study was conducted using baseline data from the Japan Multi-Institutional Collaborative Cohort (J-MICC) study. The baseline survey was conducted from 2005 to 2014 by recruiting individuals aged 35–69. Information regarding dietary intake and biometric measurements were obtained. Dietary Diversity Score (DDS) was calculated from the data based on the food frequency questionnaire. A multiple logistic regression analysis was conducted to analyze the association between DDS and metabolic syndrome.

Results

In total, 75,332 participants were included for analysis. Inverse associations were observed between a high DDS and metabolic syndrome (adjusted odds ratio, 0.83 [95% confidential interval 0.76–0.92]). Likewise, a high DDS was associated with reduced odds of a high body mass index and hypertension. No significant associations were observed between the DDS and serum triglyceride, fasting blood glucose, or high-density lipoprotein cholesterol values.

Conclusion

The findings of this study emphasize that dietary diversity has inversed associations with metabolic syndrome. Promoting a diverse and balanced diet can be a potential strategy for mitigating the burden of metabolic syndrome.
