The biomarker was detected in 23.5% of participants and was linked to increased risk of stroke and high blood pressure.
The study found that levels of IL-6 and hs-CRP varied with sleep duration in women but not men. Shorter sleep was linked to increased inflammation levels, while longer sleep was associated with poorer health outcomes.
A study of 1,008 patients with obstructive sleep apnea found a significant association between REM-related OSA and type 2 diabetes, with adjusted odds ratios up to 2.8 times higher in middle-aged participants. The researchers suggest that REM-related OSA may be an early marker for type 2 diabetes, especially in women and younger patients.
A study shows that CPAP therapy significantly improves complaints of fatigue, tiredness, and sleepiness in patients with obstructive sleep apnea. Good adherence to CPAP was associated with improved symptoms, particularly among inadequately treated participants.
A study of twins found that habitual sleep duration affects body mass index (BMI), with optimal sleep duration between 7 and 8.9 hours per night. The relationship remained even after controlling for genetics and environment.
A recent study found a significant association between obstructive sleep apnea (OSA) and weight gain. Participants with severe OSA had an increased BMI by 0.52 kg/m2 compared to those with moderate OSA. The study suggests that people with more severe OSA may be more likely to experience weight gain over time.
