Adherence to a Healthy Sleep Pattern Linked to a Lower Risk of CKD

Takeaway

• Adherence to an overall healthy sleep pattern was associated with a lower risk of chronic kidney disease (CKD), especially in those without pre-existing hypertension and those aged ≤60 years.

Why this matters

• Findings emphasise that CKD interventions focusing on sleep behaviours would be more effective at an early age and before the onset of hypertension.

Study design

• An analysis of 392,218 participants without CKD (age, 37-73 years), identified from the UK Biobank (2006-2010).

• Funding: Grants from the National Heart, Lung, and Blood Institute and the National Institute of Diabetes and Digestive and Kidney Diseases.

Key results

• During a mean follow-up of 11.1 years, 18,842 cases of incident CKD were reported.

• Compared with a poor sleep pattern (score, 0 to 1), a healthy sleep pattern (score, 5) was associated with a lower risk of CKD (adjusted HR [aHR], 0.77; 95% CI, 0.71 to 0.84).

• Compared with their counterparts, the aHRs (95% CIs) for CKD were:

  • 0.90 (0.88 to 0.93) for sleep of 7-8 hours/day;

  • 0.97 (0.94 to 1.00) for early chronotype;

  • 0.90 (0.87 to 0.93) for no frequent insomnia;

  • 0.99 (0.96 to 1.02) for no frequent snoring; and

  • 0.89 (0.83 to 0.96) for no frequent daytime sleepiness.

• A healthy sleep pattern (score, 5) vs poor sleep pattern (score, 0 to 1) was strongly associated with a lower risk of CKD in patients without hypertension (aHR, 0.67; 95% CI, 0.57 to 0.80; P_interaction = 0.003) vs those with hypertension and in patients aged ≤60 years (aHR, 0.73; 95% CI, 0.64 to 0.82; P_interaction < 0.001) vs their older counterparts.

Limitations

• Sleep behaviours were measured only at recruitment.

• Risk of residual confounding.
