Kim, Ahn, and Son: Risk of Metabolic Syndrome according to Intake of White Rice and Kimchi in Korean Adults: based on the 6th Korea National Health and Nutrition Examination Survey, 2013–2015

Abstract

Objectives

This study was conducted to examine the relationship between white rice and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults.

Methods

Dietary intake and health data of 8289 subjects aged 19 years and over from the 2013–2015 Korea National Health and Nutrition Examination Survey (KNHANES) were used. Daily total intake of white rice and Kimchi was assessed by 24-hour recall data. Multivariate logistic regression analysis was used to estimate the risk of Mets according to the daily intake of white rice and Kimchi.

Results

The highest intake of white rice and Kimchi was associated with a higher risk of metabolic syndrome (Q1 vs Q5, multivariable adjusted OR=1.45, 95% CI: 1.03–2.03) in women. In addition, a significantly increased risk of elevated blood pressure (multivariable adjusted P for trend 0.0459) was associated with a higher intake of white rice and Kimchi in women. There was no significant trend in the risk of metabolic syndrome according to the intake of white rice and Kimchi in men.

Conclusions

A higher intake of white rice and Kimchi was only associated with an increased risk of metabolic syndrome in women indicating it is necessary to consume more various food groups beside white rice and Kimchi, especially in women.

Values are expressed as mean±SE for continuous variables and percentage for categorical variables.

Q1, Q3, Q5 are the lowest, middle, and highest quintiles, respectively.

1) P value is P for trend determined by GLM for continuous variables and P for difference by Chi-square test for categorical variables.

2) Monthly alcohol consumption was defined as percentage of people who drank more than once a month for the past year.

3) Regular exercise was defined as walking at least 30 minutes a day, more than 5 times per week.
