Sleep hours and late dinner are not associated with combined outcomes in peritoneal dialysis patients

Abstract

Aim To evaluate the association between late-night dinner and sleep duration with the combined outcomes in peritoneal dialysis (PD) patients. Methods This is a prospective cohort study. Patients undergoing outpatient PD treatment for at least 3 months, aged≥18 years, of both sexes, were included. Demographic, clinical, laboratory, and anthropometric data were collected. Late-night dinner was defined as the habit of eating up to 2 h before bed at least three times a week. The average time in hours of sleep was recorded on 3 days of the week. The patients were followed for 6 months, and the outcomes were the occurrence of hospital admission and peritonitis during the period. Data was expressed as mean and standard deviation or median and interquartile range or absolute (n) and relative (%) values. The significance level adopted was 5%. Results Included 49 patients; 53.1% were women and the mean age of 60.7±16.1 years. Around 32.7% of patients had a late-night dinner habit. The average sleep time was 8.6±2.1 h and 36.7% of patients had combined outcomes. Furthermore, the prevalence of malnutrition was higher in the group of patients with combined outcomes. Patients with hours of sleep<6 and≥9 h were more malnourished according to 7-point Subjective Global Assessment (SGA-7p). No association was found between hours of sleep and late-night dinner with combined outcomes. Conclusion No significant association was found between sleep hours and late-night dinner and the development of outcomes. However, due to the short period of follow-up, more studies are needed.
