Dietary sodium intake and mortality: the National Health and Nutrition Examination Survey (NHANES I)

Abstract Objectives To examine the trends in the consumption of fermented foods and sodium intake over time, using data from the Korean National Health and Nutrition Examination Survey (KNHANES). Methods This research study is a secondary analysis using KNHANES data from 1998 to 2016 which is a cross-sectional survey. The target population was Korean adults, ages ≥19 years and the total number was 76,199, with 32,324 men and 43,875 women. Assessment of fermented food consumption and sodium intake was conducted via analysis of 24-hour dietary recall data. Multivariate linear regressions and logistic regressions were performed to calculate the P for trends by applying strata, cluster, and sampling weights by SAS PROC SURVEY. Age was standardized for all analyses in order to calculate P for trends for education, income, fermented food consumption, and sodium intake. Results A significant decline in fermented food consumption was observed in both men and women (P < 0.0001). Among fermented foods, kimchi consumption was greatly reduced while pickled vegetables consumption showed a marked increase. Similarly, sodium intake from fermented foods significantly declined over time in both men and women (P < 0.0001). Conclusions The consumption of fermented foods and sodium intake from fermented foods by Korean adults significantly decreased over time from 1998 to 2016. Funding Sources N/A.

Abstract Background: This study aimed to evaluate the relationship between sodium intake and insulin resistance indices. Methods: A total of 718 Korean children and adolescents (411 boys) aged 10–18 years who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) were included in the study. The urinary sodium to urinary creatinine ratio was used as a surrogate for sodium intake. The homeostatic model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) were used as indices of insulin resistance. Results: The mean urinary sodium to urinary creatinine ratio was 11.34 in males and 10.17 in females. The urinary sodium to urinary creatinine ratio was significantly positively correlated with HOMA-IR (r=0.165, p<0.001) and inversely correlated with QUICKI (r=−0.181, p<0.001) in Pearson’s correlation analyses. In a multivariate linear regression analysis, the urinary sodium to urinary creatinine ratio was independently and significantly positively associated with HOMA-IR (β=0.073, p=0.018) and significantly inversely associated with QUICKI (β=−0.080, p=0.007) after adjustment for possible confounders. HOMA-IR was independently and significantly positively associated with the urinary sodium to urinary creatinine ratio (β=0.087, p=0.018), whereas QUICKI was independently and significantly negatively associated with the urinary sodium to urinary creatinine ratio (β=−0.097, p=0.009) after controlling for confounders. Conclusions: Our results suggest that sodium intake, as estimated by the urinary sodium to urinary creatinine ratio, may be independently associated with insulin resistance in children and adolescents.
