Aim: There is a need to understand autosomal dominant polycystic kidney disease (ADPKD) patients’ dietary habits since dietary interventions may have potential effects on ADPKD. In this study, we aimed to analyze the relationship between dietary nutrient intake and total kidney volume (TKV). Methods: This cross-sectional study was conducted on 54 ADPKD patients recruited from the Nephrology outpatient clinic between June and July 2014. TKV was determined by magnetic-resonance imaging and general characteristics, biochemical and urinary parameters were determined. The nutrient intakes of patients were calculated using the three-day dietary records obtained on three consecutive days. Results: The total kidney-volume median was found to be 1407 mL. Patients’ total dietary energy and protein intakes were 25.8±9.4 kcal/kg, 0.9±0.3 g/kg, respectively. The percentage of carbohydrates, protein, and fat in energy was 49±7%, 14±3%, 37±7%, respectively. The mean intakes of thiamin, riboflavin, B6, calcium, magnesium, and zinc were sufficient, the mean dietary potassium intake was insufficient; and sodium intake was excessive in both sexes. In females, there was a negative but weak correlation between dietary vitamin C intake and TKV. In males, a negative but weak correlation was found between TKV and dietary intake of fiber, water, vitamin B6, vitamin K, magnesium, and iron. Conclusions: Dietary micronutrient intake may affect TKV according to sex.
