Abstract

BACKGROUND:

The multiple dietary restrictions recommended to hemodialysis patients may be difficult to achieve and, at the same time, may result in nutritional deficiencies rendering a poor dietary quality. We here assess the dietary quality and adherence to renal-specific guideline recommendations among hemodialysis patients from a single center in Canary Islands, Spain.

METHODS:

Cross-sectional study, including 91 patients undergoing maintenance hemodialysis. Clinical data and 3-day dietary records were collected. We compared patient's reported nutrients intake with guideline recommendations. We also evaluated their alignment with current American Heart Association dietary guidelines for cardiovascular prevention.

RESULTS:

Seventy-seven percent and 50% of patients consumed less than the recommended daily energy and protein, respectively. Although half of the patients met the recommendations for dietary fat intake, this was accounted by an excess of saturated fat in 92% of them. Only 22% consumed sufficient fiber. A very small proportion of patients (less than 50%) met the requirements for vitamins and other micronutrients. Insufficient dietary intake was observed in most patients for all vitamins except for cobalamin. Similarly, inadequate dietary intake was observed for many minerals, by both excess (phosphorus, calcium, sodium, and potassium) and defect (magnesium). Most patients met the recommendations for iron and zinc in their diets.

CONCLUSIONS:

A large proportion of hemodialysis patients at our center did not meet current renal-specific dietary recommendations. The quality of the diet was considered poor and proatherogenic according to American Heart Association guidelines.
