Although sleep disruption has been studied extensively in cardiovascular and metabolic diseases, its link with chronic kidney disease (CKD) is unclear. The Nurses' Health study has revealed that shorter the sleep duration, more rapid the decline in kidney function.
The research team led by Ciaran Joseph McMullan analyzed information on 4238 participants from the Nurses' Health Study with kidney function measurements on at least two occasions over an 11-year period. They found that women sleeping less than five hours per night had a 65% increased likelihood of experiencing a rapid decline in kidney function compared with women sleeping seven to eight hours per night, after controlling for various factors.
‘Researchers have observed that renal physiology is adversely affected by disruption in sleep. Women who slept for less than five hours each night had a 65% increased likelihood of experiencing a rapid decline in kidney function compared with women who slept for seven to eight hours.’
McMullan said, "The findings of this paper coupled with research from others suggest that renal physiology may be adversely effected by disruption in sleep, including sleep restriction."
The findings have been presented at the San Diego Convention Center in San Diego, CA.
