title: DASH dietary pattern and chronic kidney disease in elderly Korean adults.
abstract: Dietary patterns are linked to risk and outcomes in chronic kidney disease (CKD). Dietary intake varies by race, region and age. The relationship between a Dietary Approaches to Stop Hypertension (DASH) diet and CKD in elderly Koreans is unclear.
  
  
  
  We conducted cross-sectional analyses of 2408 community-dwelling elderly participants from the Korean National Health and Nutrition Examination Survey (2011-2012). DASH dietary patterns for six nutrients (protein, fiber, calcium, potassium, total fat and sodium) were collected by 24 h recall. DASH-US (based on the US recommendations) and DASH-KQ (Korean quartile) scores were generated by summing the scores for the six nutrients. Multivariate logistic regression analysis was used to calculate odds ratio (OR) for the association between a DASH diet and CKD.
  
  
  
  Mean subject age was 72.4±5.1 years, 13.9% had CKD and 23.8% had diabetes. Protein, fiber, calcium and potassium intake was lower in CKD than non-CKD participants. In multivariate logistic regression analysis adjusted for age, sex, body mass index, comorbid conditions and other factors, a high DASH score was associated with a low odds for CKD based on DASH-US (OR=0.78, 95% confidence interval (CI), 0.65-0.94, P=0.009) and DASH-KQ (OR=0.95, 95% CI, 0.91-0.99, P=0.022). In six nutrients of DASH diet, high fiber intake showed a low odds for CKD in the DASH-KQ model (P for trend=0.010).
  
  
  
  Our findings suggest that higher adherence to a DASH diet and higher fiber intake are associated with lower odds of CKD in elderly Koreans. These results should be corroborated through longitudinal studies of the association between a DASH diet and high-fiber diet on the risk of developing CKD.
