Waist circumference as a predictor of mortality in peritoneal dialysis patients: a follow-up study of 48 months.

Body-fat gain is a common finding among peritoneal dialysis (PD) patients, and the accumulation of adipose tissue occurs predominantly in the abdominal area. Waist circumference (WC) is a reliable marker of abdominal obesity and its association with worse outcomes has been demonstrated in non-dialysis and haemodialysis patients. We aimed at investigating whether WC measurements as well as the changes over time in WC were able to predict mortality in PD patients.

Variations in adiponectin levels in patients with chronic kidney disease: a prospective study of 12 months.

Background: Cardiovascular complications remain the main cause of mortality in patients with chronic kidney disease (CKD). Adiponectin is an adipose tissue-derived protein that carries important cardioprotective properties. We aimed at investigating the determinants of adiponectin levels in CKD patients.

Waist circumference as a predictor of adiponectin levels in peritoneal dialysis patients: a 12-month follow-up study.

Objectives: This prospective study, conducted at the dialysis unit of the Nephrology Division, Federal University of Sao Paulo-Oswaldo Ramos Foundation, Brazil, aimed to evaluate whether waist circumference (WC) can predict adiponectin levels in patients undergoing peritoneal dialysis (PD).

Methods: Among 115 patients on PD at a single dialysis center who were evaluated at 6 and 12 months, 57% were men, 31% had diabetes, mean age was 52.8 ± 16.

Usefulness of waist circumference as a marker of abdominal adiposity in peritoneal dialysis: a cross-sectional and prospective analysis.

Background: Waist circumference (WC) has been well recognized as a surrogate marker of abdominal adiposity. In peritoneal dialysis (PD) patients, however, aspects related to this dialysis modality, such as abdominal distension, presence of catheter and frequent hernia, raise questions regarding the reliability of WC measurements. Herein, we investigated for the first time whether WC is a reliable marker of abdominal adiposity in PD population.

Underreporting of energy intake in peritoneal dialysis patients.

Objectives: This study aimed to assess the prevalence of underreporting among patients treated by peritoneal dialysis (PD), and to investigate whether the reported energy intake is influenced by overweight status in this population.

Design: This was a prospective, observational study.

Setting: This study took place at the Dialysis Unit of the Nephrology Division, Federal University of São Paulo-Oswaldo Ramos Foundation, São Paulo, Brazil.

Factors associated with body-fat changes in prevalent peritoneal dialysis patients.

Background: Changes in body fat (BF) were shown to occur over time in peritoneal dialysis (PD) patients. However, the factors associated with BF changes have not been fully investigated in this population.

Methods: We studied 45 patients (25 were male; age, 53, SD +/- 15 years; 21 continuous ambulatory peritoneal dialysis/24 automated peritoneal dialysis; PD vintage, 14 ([range, 3 to 104] months; 40% were diabetic; 31% were previously treated by hemodialysis).
