Assessing anxiety, depression and insomnia symptoms among Ebola survivors in Africa: A meta-analysis

Abstract

Background During health disaster events such as the current devastating havoc being inflicted on countries globally by the SARS-CoV-19 pandemic, mental health problems among survivors and frontline workers are likely concerns. However, during such health disaster events, stakeholders tend to give more precedence to the socio-economic and biomedical health consequences at the expense of mental health. Meanwhile, studies show that regardless of the kind of disaster/antecedent, all traumatic events trigger similar post-traumatic stress symptoms among survivors, families, and frontline workers. Thus, our study investigated the prevalence of anxiety, depression and insomnia symptoms among survivors of the 2014–2016 Ebola virus disease that plagued the West African sub-region. Methods We systematically retrieved peer-reviewed articles published between 1970 and 2019 from seven electronic databases, including Google Scholar, MEDLINE, PsychInfo, PubMed, Scopus, Springer Link, Web of Science on Ebola and post-traumatic stress disorder symptoms. A comprehensive hand search complemented this literature search. Of the 87 articles retrieved, only 13 met the inclusion criteria for this meta-analysis. Results After heterogeneity, influence, and publication bias analysis, our meta-analysis pooled proportion effects estimates showed a moderate to a high prevalence of anxiety (14%; 99% CI: 0.05–0.30), depression (15%; 99% CI: 0.11–0.21), and insomnia (22%; 99% CI: 0.13–0.36). Effect estimates ranging from (0.13; 99% CI: 0.05, 0.28) through to (0.11; 99% CI: 0.05–0.22), (0.15; 99% CI: 0.09–0.25) through to (0.13; 99% CI: 0.08–0.21) and (0.23; 99% CI: 0.11–0.41) to (0.23; 99% CI: 0.11–0.41) were respectively reported for anxiety, depression and insomnia symptoms. These findings suggest a significant amount of EVD survivors are struggling with anxiety, depression and insomnia symptoms. Conclusion Our study provided the first-ever meta-analysis evidence of anxiety, depression, and insomnia symptoms among EVD survivors, and suggest that the predominant biomedical health response to regional and global health disasters should be complemented with trauma-related mental health services.

Understanding the Impact of the COVID-19 Pandemic, Lockdowns and Social Isolation on Sleep Quality

“…Insomnia symptoms frequently manifest in the face of acute life changes or stressors, such as pandemics, 69 and unsurprisingly, studies conducted during the COVID-19 pandemic have overwhelmingly and consistently shown a significant increase in insomnia symptoms, ranging from 18% to 63%. 16 , 37 , 70 , 71 Whilst some of these insomnia symptoms may be categorized as mild, it has been well accepted that transient sleep disturbances can later lead to chronic insomnia disorders.…”

The prevalence of mental health outcomes among eating disorder patients during the COVID-19 pandemic: A meta-analysis

“…It is well-established that patients with eating disorders are already particularly well-characterized by eating-related concerns and are known to suffer from various psychological comorbidities [10]. It is important to note that patients with mental disorders struggled previously in the past during different pandemics such as Ebola [11]. Thus, the stress of the ongoing pandemic may potentially negatively impact these patients [12].…”

Prevalence of Sleep Disturbances During COVID-19 Pandemic in a Nepalese Population: A Cross-Sectional Study

“…13 Survivors of an Ebola epidemic in Africa reported feeling anxiety (14%), depression (15%), and insomnia (22%). 14 The sleep problems arising during the coronavirus disease (CO-VID-19) outbreak are severe and affect approximately 40% of people. 15 SARS-CoV-2 was first identified in December 2019 in Wuhan city, central China.…”

“…Each item is scored on a 5-point Likert scale from 0 to 4, yielding a total score of 0-28. The results were interpreted as follows: absence of insomnia (0-7), subthreshold insomnia (8)(9)(10)(11)(12)(13)(14), moderate insomnia (15)(16)(17)(18)(19)(20)(21), and severe insomnia (22)(23)(24)(25)(26)(27)(28). Numerous studies have proven that the ISI is a valid and reliable instrument.…”
