Sleep duration and leg restlessness associated with increased risk of CKD
According to the 2019 Global Disease Burden (GDB), the age-standardized prevalence and death rate for Chronic Kidney Disease (KD) are 8724 and 15.9 per 100,000 people respectively. The percentage change in prevalence and death between 1990 and 2017 was 1.2% and 2.8%, respectively [1]. Thus, given the increasing prevalence of CKD, identifying potential risk factors can be helpful in preventing it.
Sleep duration and leg restlessness may be associated with an increased likelihood of CKD suggests a new study published in the BMC Nephrology
The relationship between sleep duration and chronic kidney disease (CKD) has received relatively little attention in the Kurdish community. Considering the ethnic diversity of Iran and the importance of the Kurdish community, the present study investigated the association between sleep parameters and CKD among a large sample of Iranian-Kurds.
Methods
This cross-sectional study was conducted among 9,766 participants (Mage: 47.33, SD = 8.27, 51% female) from the Ravansar Non Communicable Disease (RaNCD) cohort study database. Logistic regression analyses were applied to examine the association between sleep parameters and CKD.
Results
Results showed that prevalence of CKD was detected in 1,058 (10.83%) individuals. Time to fall asleep (p = 0.012) and dozing off during the day (p = 0.041) were significantly higher in the non-CKD group compared to the CKD group. Daytime napping and dozing off during the day in females with CKD were significantly more than males with CKD. A long sleep duration (> 8 h/day) was associated with 28% (95% CI: 1.05, 1.57) higher odds of CKD compared to normal sleep duration (7 h/d), after adjusting for confounding factors. Participants who experienced leg restlessness had a 32% higher probability of developing CKD than those who did not experience leg restlessness (95% CI: 1.03, 1.69).
Results suggest that sleep duration and leg restlessness may be associated with an increased likelihood of CKD. Consequently, regulating sleep parameters may play a role in improving sleep and preventing CKD.
