A study found that husbands with OSA are more likely to adhere to CPAP if their wives share the bed. The results suggest that when both partners sleep together, the husband is more likely to continue using his CPAP mask. This is because CPAP can control snoring and excessive movements that disturb both partners' sleep.
A new study published in the Journal of Clinical Sleep Medicine (JCSM) has found that obesity can predict upper airway obstruction among children. The research, conducted on 190 Australian children aged four to 12, suggests that body mass is a significant predictor of upper airway obstruction severity, but its impact varies by ethnicity.
