Background

This study aimed to clarify the association between food security and the prevalence of chronic kidney disease in Korean older patients.

Methods

We analyzed the variables of The Korea National Health and Nutrition Examination Survey V (2010–2012), and VI (2013–2015) while merging data from the food security questionnaire for four years. We included 15,945 participants, performed propensity score-matched analysis by quartile of household income (i.e., low, low-mid, high-mid, high) and sex, and presented the results by age group (Figure 1).

Results

Systolic blood pressure and proportion of current smokers were significantly higher in the elderly group, compared with the middle-aged group. The prevalence of hypertension, diabetes mellitus (DM), metabolic syndrome, and chronic kidney disease (CKD) did not differ significantly by income level in the elderly group. The food security questionnaire revealed that food security insurance was significantly lower in the low-income level (1^st quartile), compared with that in the high-income level (4^th quartile). The logistic regression analysis for the association between the prevalence of chronic disease and food insecurity confirmed no significant association between hypertension and DM.

Conclusion

There might be a correlation between self-reported food insecurity and the incidence of chronic kidney disease (CKD), particularly in the elderly populations older than 65 years.
