Clinical Recognition Of Obstructive Sleep Apnea In A Population-Based Sample, Mark R. Zellmer Jan 2010

Clinical Recognition Of Obstructive Sleep Apnea In A Population-Based Sample, Mark R. Zellmer

Walden Dissertations and Doctoral Studies

Obstructive sleep apnea (OSA), a disorder in which the airway intermittently collapses and obstructs during sleep, is associated with increased cardiovascular and cerebrovascular morbidity and mortality, increased risk of motor vehicle accidents, metabolic syndrome, hypertension, and depression. Treatment of OSA attenuates or reverses many of these associated risks. However, most cases of OSA are unrecognized and untreated. The two most recent studies using 1990s data found that only 6.5 - 15.4% of OSA cases, depending on severity, are clinically recognized in mixed gender populations. Based on a conceptual framework of improved physician awareness of OSA, and reduced diagnostic access bias …

The Relationship Between Religious And Spiritual Factors And The Perpetration Of Intimate Personal Violence, Robbin G. Todhunter

Walden Dissertations and Doctoral Studies

Intimate partner violence (IPV) is a multifaceted social issue that affects the Christian faith community as it does the secular community. Though the literature reflects some understanding of general correlates and possible antecedents to IPV within the Christian community, the impact of religious and spiritual factors tends to be homogenized and is often misjudged. Allport's theory of intrinsic and extrinsic religious orientation provided a platform for investigating Christian male-perpetrated IPV. This quantitative study utilized survey design and measured the impact of 10 select religious and spiritual factors on the probability of physical or sexual IPV perpetration. Archival data from Wave …
