ntroduction
O
bejective
Hemodialysis patients with malnutrition have significantly higher morbidity and mortality. The major cause of malnutrition is inadequate dietary intake. Burrowes and his colleagues demonstrate that hemodialysis patients’ dietary intake are difference between dialysis treatment days and non-dialysis treatment days. However, there is no paper mentioned about the difference among weekend and dialysis treatment days or non-dialysis treatment days.
To evaluate the dietary energy intake and protein intake between male and female hemodialysis patients among dialysis treatment days, non-dialysis treatment days and weekend.
M
ethods
Ninety-five adults who received hemodialysis treatment for at least 3 months were recruited. All subjects were from Taipei Medical University Hospital or Wanfang Hospital. The demographic information, dry body weight, serum albumin, Kt/V and 3-day dietary record were collected from Apr. 2010 to Dec.2010. Geriatric nutritional risk index (GNRI）was used as nutritional parameter. We analyzed the dietary energy and protein intake and compared with K/DOQI guideline.
R
esults and Discussion
Very fewer female subjects had adequate dietary intake on weekend than dialysis day and non-dialysis day. Too much fluid adherence for hemodialysis subjects may contribute to poor dietary intake on weekend. Zabel and his colleagues proposed that male hemodialysis patients have better appetite than female dialysis patients.
C
onclusion
Our study revealed that female hemodialysis patients had poor dietary intake during the weekend and much lower than K/DOQI’s recommendation. We suggest that female hemodialysis patients may need more
intervention on their dietary intake to prevent worst prognosis.
