Rationale for Examining Sleep Patterns in CKD
CKD affects more than 10% of adults worldwide and remains closely linked to cardiometabolic conditions such as hypertension, diabetes,and cardiovascular disease. Sleep disturbances are common in individuals with CKD,with studies reporting high rates of insomnia, sleep apnea, and restless legs syndrome.
Previous research has suggested a bidirectional relationship between sleep and CKD progression. Short sleep duration has been associated with an increased risk of developing CKD, while CKD itself can disrupt sleep patterns due to factors such as uremia, nocturia, and pain. However, the impact of weekend sleep recovery-the extent to which individuals ”catch up” on sleep during weekends after experiencing sleep restriction during the week-on CKD risk remains unclear.
to investigate this question, researchers conducted a study involving 14,606 adults from the multi-Ethnic Study of Atherosclerosis (MESA). Participants self-reported their weekday and weekend sleep duration,and were followed for an average of 7.8 years to assess the incidence of CKD.
The findings revealed that individuals with shorter weekday sleep duration (<7 hours) who also exhibited greater weekend sleep recovery had a lower risk of developing CKD compared to those with similar weekday sleep duration but less weekend sleep recovery. Specifically, for each additional hour of weekend sleep recovery, the risk of CKD decreased by 8%.
“Our findings suggest that modest weekend sleep recovery may be protective against CKD, particularly for individuals who are chronically sleep-deprived during the week,” explained lead author Dr.
Adults who routinely sleep in on weekends to make up for lost sleep during the week may not be protecting their kidneys as much as they think. A new study suggests that while getting enough sleep overall is crucial, simply “catching up” on weekends doesn’t appear to lower the risk of chronic kidney disease (CKD).
- Data Source: Researchers analyzed data from the National Health and Nutrition Examination Survey (NHANES) spanning 2017-2020, combining cycles due to disruptions from the COVID-19 pandemic.
- Study Population: The final study group included 4942 adults aged 20 and older, representing roughly 156 million US adults. The group was 51.2% female, with an average age of 46.8 years.
- CKD Definition: Chronic kidney disease was defined as either an estimated glomerular filtration rate (eGFR) below 60 mL/min/1.73 m2 or a urine albumin-to-creatinine ratio of at least 30 mg/g.
Weekend catch-up sleep (WCS) was resolute by calculating the difference between weekend and weekday sleep duration. Investigators wanted to understand if this practice could offset the known link between insufficient sleep and metabolic and cardiovascular problems, and whether it had any impact on CKD risk.
