Key result
Higher dietary antioxidant quality is linked to ~83% lower odds of elevated SBP but not MetS.
Why the study?
The authors aimed to investigate whether adherence to the dietary antioxidant quality score is associated with metabolic syndrome in a Tehranian population.
Does adherence to a dietary antioxidant quality score improve metabolic syndrome and its components in healthy adults?

Greater adherence to a dietary antioxidant quality score is associated with lower systolic blood pressure but not overall metabolic syndrome in healthy Iranian adults.
Null DAQS-MetS link in young Tehran adults warrants no practice change; leaves open prospective confirmation for SBP benefit.
We aimed to investigate whether adherence to dietary antioxidant quality score (DAQS) is associated with metabolic syndrome (MetS) among the Tehranian population. This cross-sectional study was conducted on 270 apparently healthy adults aged between 18 and 45 years old who lived in Tehran, Iran, between February 2017 and December 2018. Participants were categorized based on tertile cut-off points of DAQs. To examine the association between DAQS and MetS and its components, we used multivariable logistic regression analysis in different models. Adherence to DAQS was associated with a significant increase for intake of vitamin B6 (P-value = 0.02), riboflavin (P-value < 0.001), folate (P-value = 0.03), selenium (P-value = 0.03), vitamin D (P-value < 0.001), and calcium (P-value < 0.001). Adherence to DAQS showed a significant decrease for odds of systolic blood pressure (SBP) (OR: 0.17, 95% CI: 0.04, 0.65, P-value = 0.03). We also found that the overall adherence to DAQS was not significantly related to MetS and its other components. In conclusion, although we observed an improvement in SBP with a greater adherence to dietary antioxidant quality score, there was no association between DAQS and metabolic syndrome and its other components.

Shahavandi et al. (2020) conducted a cross-sectional in Metabolic syndrome (n=270). Dietary antioxidant quality score (DAQS) vs. Lower tertiles of DAQS was evaluated on Metabolic syndrome and its components (OR 0.17, 95% CI 0.04-0.65, p=0.03). Greater adherence to the dietary antioxidant quality score was associated with decreased odds of elevated systolic blood pressure (OR 0.17; 95% CI 0.04-0.65; P=0.03), but not with metabolic syndrome.
