Abstract

BackgroundNutrition has been widely recognized to influence the risk of kidney stone formation. Therefore the aim of our study was to assess: a whether usual diet of women with idiopathic calcium nephrolithiasis ICN living in Parma Northern-Italy is different compared to healthy controls, b how their diet differs from Italian National guidelines and c whether it is related to nephrolithiasis clinical course.

Methods143 women with recurrent ICN mean age 43 ± 13 ys and 170 healthy women mean age 42 ± 11 ys were enrolled. All women completed a food frequency questionnaire for the last 60-days and a 3-day dietary diary analysed with a dedicated software.

ResultsStone formers showed a higher consumption of sausages, ham, meat and sweets than healthy controls 43.1% vs 11.1%, 29.4% vs 13.9%, 21.6% vs 4.2%, 66.7% vs 18.1%, p < 0.001. The 3-day diary analysis showed an intake of calories, carbohydrates, lipids and non-discretionary sodium about 10% higher than healthy controls p < 0.001. Finally, after dividing the population into 3 age groups ≤30, 31-40, > 40 years, the differences described above were amplified in the class ≤30 years, where nephrolithiasis presented a more serious course shorter recurrence interval, greater stone-rate. In this age group the intake of fruit and vegetables was notably lower than guideline recommendations.

ConclusionsWe conclude that the usual diet of women with recurrent ICN is different from controls and characterized by low intake of fruits and vegetables and higher consumption of simple sugars and foods with high protein and salt content. This dietary imbalance could play a role in the ICN pathogenesis, especially in younger women.
