Body dysmorphic disorder in patients attending a dermatology clinic in Nigeria: sociodemographic and clinical correlates

Abstract: Background: Body dysmorphic disorder is a relatively common psychiatric disorder in the context of dermatology and cosmetic and plastic surgery but is underdiagnosed and underreported in Africa. Objective: To evaluate the prevalence of body dysmorphic disorder and symptoms of anxiety/depression and determine their sociodemographic and clinical correlates. Methods: A systematic random sampling design was made to recruit 114 patients with skin diseases. Sociodemographic and clinical data were obtained. The Body Dysmorphic Disorder Modification of the Yale-Brown Obsessive-Compulsive Scale, Hospital Anxiety and Depression Scale was administered, and data were analyzed using SPSS 20. Results: Mean age of participants was 37.70±17.47 years, and 67/114 (58.8%) were females. Prevalence of body dysmorphic disorder was 41/114 (36.0%), and prevalence of anxiety/depression symptoms was 35/114 (30.7%). Prevalence of body dysmorphic disorder in patients with anxiety/depression symptoms was 15/41 (36.6%), and patients with facial disorders expressed the highest burden of anxiety/depression symptoms, in 15/35 (42.9%). Factors associated with significantly higher mean body dysmorphic disorder include age<50years (p=0.039), and anxiety/depression (p<0.001), education below high school was associated with higher mean anxiety/depression score (P= 0.031). In a binary logistic regression model, presence of anxiety/depression symptoms was predictive of body dysmorphic disorder (OR=10.0, CI: 4.1-28.2, p<0.001). Study limitations: the study is uncontrolled, conducted in a single source of care, thus limiting generalization to nonrelated settings. Conclusion: Prevalence of body dysmorphic disorder is high among dermatology patients and most prevalent in facial disorders. Facial diseases are associated with the highest burden of anxiety/depression symptoms. This is a clarion call for dermatologists to routinely assess for body dysmorphic disorder and appropriately refer affected patients to mental health care.

Prevalence of End-Digit Preference in Recorded Blood Pressure By Nurses: a Comparison of Measurements Taken by Mercury and Electronic Blood Pressure-Measuring Devices

Objectives: When compared with the use of a mercury sphygmomanometer; the use of a validated digital blood pressure (BP) measuring device eliminates the risk of exposure to mercury. Digital devices are also associated with a lesser degree of end-digit preference (EDP). EDP refers to the occurrence of a particular end digit more frequently than would be expected through chance alone. There have been only a few reports from Africa on the occurrence of EDP in BP measurement. This study examined EDP in BP taken by nurses before and after the introduction of a digital BP-measuring device.Design: The design was a retrospective study.Settings and subjects: We reviewed the BP readings of 458 patients who presented at the dedicated clinic for people living with human immunodeficiency virus/acquired immune deficiency syndrome of Ladoke Akintola University of Technology Teaching Hospital; Osogbo; Nigeria; before and after the introduction of the digital BP-measuring device.Outcome measures: The prevalence of end-digit zero of systolic and diastolic BP readings before and after the introduction of the digital device was compared using McNemar's test.Results: There was a large and significant fall in end-digit zero when BP readings that were taken using the mercury and digital devices were compared (systolic 98.1 vs. 10.9 ; p-value 0.001; diastolic 97.1 vs. 14.9 ; p-value 0.001 (McNemar's test).Conclusion: There was a significant reduction in the frequency of end-digit zero when BP was taken with the digital device rather than the mercury device. Regular training and certification of healthcare workers in BP measurement is recommended to ensure a high quality BP measurement standard
