Exploring Factors Associated with Sleep Quality After Lung Transplantation.
Seol Ju E Moon, Megan Kazakoff, Kristen B Jones and 6 others
PMID 40552381WHAT IT FOUND
65 of 88 lung transplant recipients reported poor sleep.
Psychological distress was the main factor linked to poor sleep, and wheezing also stood out; daily step count did not differ between sleep groups.
Key findings
0165 participants (73.9%) reported poor sleep quality.
02In the model examining symptom burden subscales, only clinically significant psychological distress was associated with poor sleep.
03Wheezing was reported by 23 participants with poor sleep quality (35.4%) and by 1 participant with good sleep quality (4.2%).

What it does not show
The study looked at one point in time, so it cannot show that psychological distress or wheezing caused poor sleep. It included only 88 recipients from one transplant clinic, and most were white adults, so the findings may not apply to all lung transplant patients. Participants had to be well enough to join an exercise trial, which may have left out sicker recipients who could have more sleep problems. Sleep was measured by questionnaire, not by sleep monitoring, and the study did not check sleep-disordered breathing or medications. Data were collected during the COVID-19 pandemic, which may have increased anxiety and depression. No formal power analysis was done before the study.
Declared interests
The authors declared no potential conflicts of interest.
The easy way to misread this
Do not conclude that treating psychological distress or wheezing will improve sleep. This study was cross-sectional and only found associations, not that either factor caused poor sleep or that an intervention would help.
