Predictive value of craniofacial and anthropometric measures in obstructive sleep apnea (OSA).

Background: Most individuals with OSA remain undiagnosed, mainly due to limited access to effective screening tools and diagnostic facilities. Therefore, the objective of this study was to identify craniofacial and anthropometric measurements that predict OSA in an Indian population.

Methods And Findings: Male subjects (n = 76) between 25 and 50 years of age were recruited for the study from the general population.

Second digit and fourth digit ratio--an adjunct tool to predict obstructive sleep apnea.

Obstructive sleep apnea (OSA) is a sleep related breathing disorder associated with high morbidity and mortality. Digit ratio (2D:4D) a sexually dimorphic trait is a putative indicator of prenatal testosterone exposure and adult testosterone level. Present study aimed at investigating the correlation between 2D:4D ratio and OSA based on the study conducted on 290 volunteered participants of both the sexes in the age range of 20-45 years.
