This study found that there is a gender-specific association between dietary diversity score (DDS) and the risk of metabolic syndrome (MetS). A higher DDS is inversely associated with the consumption of grains but positively associated with the consumption of fruits, non-salted vegetables, fish, and milk. Furthermore, a higher DDS is significantly associated with a lower risk of MetS, abdominal obesity, and hypertriglyceridemia in men.
Dietary diversity is recognized as a key indicator of dietary quality and is known to affect the burden of non-communicable diseases. This study examined the gender-stratified association between dietary diversity score (DDS) and risk of metabolic syndrome (MetS) in 5468 adults aged 40-69 years during a 12-year follow-up of the Korean Genome and Epidemiology Study (KoGES). DDS was calculated according to the consumption of the five food groups based on the Dietary Reference Intakes (DRIs) for Koreans. The Cox proportional hazard model was used to evaluate MetS risk according to DDS. A higher DDS was negatively associated with the consumption of grains but positively associated with the consumption of fruits and non-salted vegetables. Furthermore, participants with a higher DDS showed higher consumption of fish and milk. Prospectively, a higher DDS was significantly associated with a lower risk of MetS in men (HR: 0.76, 95% CI: 0.63-0.92, p < 0.01). In all participants, a higher DDS was inversely associated with the incidence of abdominal obesity (men, HR: 0.76, 95% CI: 0.62-0.93, p < 0.01; women, HR: 0.79, 95% CI: 0.67-0.94, p < 0.01). Furthermore, men with a higher DDS had a lower risk of hypertriglyceridemia (HR: 0.83, 95% CI: 0.71-0.97, p < 0.05). These findings suggested that eating a more varied diet might have favorable effects on preventing MetS in Korean adults.
