The association between curry-rice consumption and hypertension, type 2 diabetes, and depression: The findings from KNHANES 2012-2016

Abstract

Background and aims: We aim to evaluate the association between curry-rice consumption, cardiovascular diseases (CVDs), type 2 diabetes (T2DB), arthritis, and depression.

Methods: 17,625 participants aged ≥18 years were recruited to obtain data on sociodemographic characteristics, lifestyle, medical history, current medications, family history, and food consumption. The association between curry-rice consumption, CVDs, T2DB, arthritis, and depression was examined using multivariable-adjusted analyses.

Results: In the logistic model, risks of elevated triglyceride (OR 0.89; 95% CI, 0.82-0.97, p = 0.006), elevated HbA1c (OR 0.81; 95% CI, 0.73-0.91, p < 0.001), and elevated glucose (OR 0.86; 95% CI, 0.79-0.94, p < 0.001) were significantly lower in the high curry-rice consumption group than in the low curry-rice consumption group. Risk of hypertension (OR 0.88; 95% CI, 0.78-0.98, p = 0.044), T2DB (OR, 0.82; 95% CI, 0.68-0.98, p < 0.001), and depression (OR 0.82; 95% CI, 0.70-0.97, p = 0.026) was significantly lower among the high curry-rice consumption group than in the low curry-rice consumption group. These findings were consistent with the results of the analysis when curry-rice consumption was treated as a continuous variable.

Conclusions: The potential health benefits resulting from the intake of curry-rice via an ordinary diet could protect the public from the burden of non-communicable diseases (NCDs) and mental health. These results highlight an ongoing need to understand the role of curry-rice in NCDs and mental health.
