Longer duration of HD was associated with lower intakes of protein, potassium, and phosphorus (p &lt;0.05). </p> </div><div class="section"> <a class="named-anchor" id="S8"> <!-- named anchor --> </a> <h5 class="section-title" id="d9304397e176">Conclusion</h5> <p id="P9">Registered dietitian nutritionists should consider issues of time and food preparation, and behavioral factors in their nutrition assessment of HD patients, and should continually monitor HD patients for changes in protein intake that may occur over time. </p> </div>
