Umbrella Review of the Global Prevalence of Conduct Disorder in Children and Adolescents.

With the ever-increasing prevalence of mental health issues worldwide, a robust synthesis of existing epidemiological data on the prevalence of Conduct disorder (CD) in children and adolescents is needed to strengthen the knowledge base. This quantitative umbrella review aims to provide a robust synthesis of evidence on the prevalence of CD children and adolescents from meta-analytic systematic reviews. We searched PubMed, Web of Science, PsychINFO, and Scopus to identify relevant articles. The study protocol has been registered with PROSPERO (CRD42023447620). The methodological quality of the studies was evaluated by using a Measurement Tool to Assess Systematic Reviews (AMSTAR). Invariance variance weighted random-effect meta-analysis was performed to pool prevalence estimates from the included articles. Seven meta-analyses, encompassing 138 primary studies and slightly over 48 million CD cases were included in this umbrella review. The quantitative analysis of these studies found a pooled prevalence of CD 3.0% (95%CI 2.0-5%) in children and adolescents, based on random effect meta-analyses. In a stratified analysis, the prevalence estimate of CD was 2.6 times higher in boys compared to girls. Evidence from our quantitative umbrella review showed that the prevalence of CD is relatively high in children and adolescents with boys 2.6 times more likely to experience the disorders when compared to girls. Our findings underlie that attention should be given to preventing, identifying, and treating CD in children and adolescents.

Prevalence of attention deficit hyperactivity disorder in adults: Umbrella review of evidence generated across the globe.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a class of neurodevelopmental disorders which is commonly diagnosed in school-age children, but it can occur in any age group. To provide a robust synthesis of published evidence on the prevalence of ADHD in adults, we conducted an umbrella review of systematic reviews and meta-analyses. METHODS: The review was guided by preferred reporting items for systematic review and meta-analysis (PRISMA). We searched PsychINFO, Web of Science, PubMed, and Scopus to retrieve pertinent studies. The review protocol was registered with PROSPERO (CRD42023389704). A Measurement Tool to Assess Systematic Reviews (AMSTAR) was used to assess the quality of the included studies. A random-effects model was used to perform a meta-analysis. RESULTS: Five systematic reviews and meta-analyses (57 unique primary studies) with data on 21,142,129 adult participants were eligible for inclusion in this umbrella review. Inverse variance weighted random effect meta-analysis of these studies indicated that the pooled prevalence of ADHD in adults was 3.10% (95%CI 2.60-3.60%). ADHD-I (the inattentive type of ADHD) remained the commonest type of ADHD, followed by ADHD-HI (the hyperactive type) and ADHD-C (the combined type). CONCLUSION: The results indicate that ADHD is relatively high in adults, with ADHD-I remaining the most common subtype. Attention should be given to preventing, reducing, identifying, and managing ADHD in adults.

Adherence to Antiretroviral Medications Among People Living With HIV in the Era of COVID-19 in Central Ethiopia and Perceived Impact of the Pandemic.

AIM: This study assessed the level of adherence to antiretroviral drugs and the associated factors among clients who have a follow-up at public health facilities in central Ethiopia. METHOD: A multi-site cross-sectional study was conducted from August 1-30, 2020 at seven public health institutions. A systematic random sampling method was used to recruit 385 participants. Data was collected using a structured interviewer-administered questionnaire. Analysis was done using descriptive statistics, and binary logistic regression model. The OR with its 95% C.I was employed to present analytic outputs. Statistical significance for the multivariable model was considered at p ≤ 0.05. RESULTS: Of the 371 participants, the majority were females (233, 62.8%), attended health centers (215, 58.0%), and were married (173, 46.6%). Eighty-nine (89, 24.0%) of the participants have at least one comorbidity. About 72 (19.0%) and 50 (13.5%) of the respondents stated that the COVID-19 has posed challenges on their follow-ups and availability of medications respectively. Nearly a half of the people living with HIV and comorbid T2DM or hypertension (29, 48.0%) reported that they had encountered an increase in the price of medications compared to the pre-COVID-19 times. About half of the respondents in the study setting have perfect adherence to antiretroviral therapy (ART) (200, 54.0%). Basic education (aOR = 3.02: 95% CI: 1.57-5.80), marriage (aOR = 2.27: 95% CI: 1.24-4.15), attendance to a health center (aOR = 0.59: 95% CI: 0.36-0.98) and sleep disturbance (aOR = 0.47: 95% CI: 0.26-0.84) showed a statistically significant association with adherence to ART. CONCLUSION: About half of the respondents in the study settings have perfect adherence to their ART medications. As multiple factors interplay in the success rate of adherence to ART, stakeholders should place and strengthen practices, such as active follow-up and tracing of cases, ensuring medication affordability (access and low pricing), and psycho-social support to patients.

Health-Related Quality of Life of Patients with Type 2 Diabetes Mellitus and Hypertension in Addis Ababa, Ethiopia.

Background: The aim of this study was to assess the health-related quality of life of patients with T2DM and hypertension attending public health facilities in Addis Ababa, Ethiopia. Methods: A cross-sectional study was conducted from 1st through 30th August 2020 at the selected institutions. Health facilities were chosen purposively based on patient load. Participants were drawn after proportional to size allocation. A translated EQ-5D-3L, and EQ-VAS instrument was used to collect the data. Analysis was done using SPSS v.26.0. Both parametric and non-parametric models were applied in the analysis. Results: Of the 409 participants included, the majority were in the age group of 46-60 (36.0%), females (56.0%), from hospitals (54.8%), jobless (25.4%), and married (63.3%). Over two-thirds of the patients reported no problems with self-care, usual activity, and depression/anxiety. All dimensions showed an increasing proportion of moderate to severe problems in the age group beyond 45. Facility type, comorbid condition and age showed a statistically significant score difference for QoL. The overall prevalence of any problem was 59.0%. Education level, visit to a health center, and marriage showed lower odds of affected HRQoL whereas, lower monthly income and presence of comorbidities were opposite. Conclusion: HRQoL of patients in the study settings was suboptimal and below the general population. Attributes, such as education, facility type, marital status, income level, and comorbid status have a statistically significant association with HRQoL. Arrangement of a safe and quality health services is paramount, especially, during the COVID-19 pandemic.

Awareness of diagnosis, treatment plan and prognosis among patients attending public hospitals and health centers in Addis Ababa, Ethiopia.

INTRODUCTION: Providing patient-centered care is one of the key focus areas of the Ethiopian Health Service Transformation Plan. To this end, improving health literacy of the community is critical. However, there is limited evidence about the health literacy of Ethiopians, especially among those who visit health facilities. OBJECTIVE: The aim of this study was to examine awareness of diagnosis, treatment plan and prognosis among patients at the time of their exit from public hospitals and health centers. METHODS: A cross-sectional study was conducted among 627 patients in two public hospitals and selected health centers in Addis Ababa, using a systematic random sampling technique from inpatient and outpatient departments (OPD). A total of 579 study participants had complete data and were included in this analysis. A structured, pre-tested and interview-administered questionnaire was used to collect data. We used proportions to describe the findings and logistic regression analyses to assess factors associated with awareness of diagnosis, treatment plan and prognosis. RESULT: About three-fifths (61.9%) and 52.8% of the study participants knew correctly their diagnosis and treatment plan respectively. More than two-thirds, 68.4%, said that they knew about the prognosis of their illness. However, only 21 (3.6%) patient medical records had information on prognosis. Gynecologic patients had significantly lower awareness about their diagnosis and treatment plan as compared to those from a general outpatient department. Emergency patients had significantly lower awareness of their treatment plan (OR = 0.27; 95% CI: 0.11,0.68) and prognosis (OR = 0.21; 95% CI: 0.09,0.50) than new OPD patients. Patients who indicated they had a good experience at their clinical assessment had significantly lower awareness of their prognosis (OR = 0.25; 95% CI: 0.08, 0.81). CONCLUSION: A significant proportion of patients didn't know their correct diagnosis, treatment plan and prognosis. This was more pronounced among gynecologic and emergency patients. More efforts are needed to strengthen patient-provider interaction.

Clinical Characteristics and Outcome of Pediatric COVID-19 Patients in Ethiopia During the Early COVID-19 Pandemic: A Prospective Cohort Study.

Introduction: Most previous pediatric COVID-19 studies reported milder disease in children. However, there are limited pediatric data from low-income settings. We aimed to assess the characteristics and outcomes of pediatric COVID-19 in Ethiopia. Setting: St. Paul's COVID-19 treatment center; a tertiary COVID-19 center. Pediatric care was provided in a dedicated ward but with a common ICU. Methods: St. Paul's Hospital COVID-19 cohort (SPC-19) included inpatient COVID-19 RT-PCR confirmed cases from August 2020 to January 2021. Data were extracted from case report forms attached to patient charts and completed by the clinicians. Data were uploaded into the Redcap database and exported to SPSS 20 for analysis. Binary logistic regression and chi-square test were used in the analysis. Results: Seventy-nine patients 0-19 years were included from the SPC-19 cohort over 6 months. Pediatric admissions accounted for 11% of cases in the cohort. The mean age (SD) was 6.9 (±6.36) years and 40 (50.6%) were female. The disease was asymptomatic or mild in 57 (72.2%), moderate in 15 (19%), and severe or critical in 7 (8.8%). The commonest presentations in symptomatic children were prostration (26.6%) followed by vomiting (12.7%), fever and cough (11.4% each), and dyspnea (10%). About 53 (67%) children had multimorbidity, and 14 (17.7%) children died. All deaths were in children with comorbidities with tuberculosis and malignancy being associated with 43% of deaths. Nearly 5% of children reported long-COVID symptoms highlighting the need for prolonged follow-up in those children. Conclusion: Despite lower admissions and severity, high mortality and morbidity was documented in our pediatric cohort. The presence of comorbidity and inadequate care organization likely contributed to high mortality. COVID-19 centers of low-income settings should emphasize optimizing the care of children with COVID-19 and multimorbidity, and vaccination should be considered in those children to prevent high morbidity and mortality.

Depression and anxiety among quarantined population during the COVID-19 outbreak in central Ethiopia.

Evidence suggests that quarantine might have a wide-ranging, substantial, and long-lasting negative psychological impact especially when the necessary preventive measures are not taken. This study assessed the prevalence and associated factors of depression and anxiety among quarantined population during the COVID-19 outbreak in central Ethiopia. A community-based cross-section study was conducted among individuals under quarantine from June 5 to July 5, 2020, in Addis Ababa, Ethiopia. The hospital Anxiety and Depression Scale (HADS) was used to assess depression and anxiety. Binary logistic regression analysis (multivariate analysis) was used to identify the potential determinants of depression and anxiety. A total of 297 participants were included in the study which makes the response rate 90.8%. The prevalence of anxiety, depression, and co-morbid anxiety and depression were 21.5%, 70.7%, and 15.8% respectively. In our multivariable analyses, stressful life events (AOR 2.61, 95%CI (1.46, 4.67)), spent time on sleeping (AOR 1.97, 95% CI (1.08, 3.62)), and believing that COVID-19 could be prevented by wearing a glove (AOR 0.30, 95% CI (0.11, 0.81)) showed a statistically significant association with anxiety, whereas being married (AOR 2.67, 95% CI (1.37, 5.22)), had stressful life event in the last six months (AOR 1.44, 95% CI (1.44, 5.25)) and spending of time by sleeping during the quarantine (AOR 1.97, 95% CI (1.42, 6.19)) predicted depression. In conclusion, the current study result indicated that a considerable proportion of individuals who were under quarantine during the COVID-19 pandemic have experienced psychological disturbances, such as anxiety and depression. The results suggest that attention needs to be given to mitigate mental health problems in the quarantined population during the COVID-19 outbreak.

The prevalence of depression among adolescent with HIV/AIDS: a systematic review and meta-analysis.

BACKGROUND: Depression is particularly common among adolescents with HIV/AIDS and has been associated with disruption of the important developmental process, subsequently leading to a wide range of negative mental, physical and psychosocial consequences, as well as poor quality of life in those population groups. Nevertheless, to the best of our knowledge, there are no prior systematic reviews and meta-analytic studies that determined the prevalence of depression among adolescents with HIV/AIDS. METHOD: We systematically searched PubMed, Scopus and Web of Science for relevant literature until May 2020. A random-effect meta-analysis was used to pool prevalence rates from individual studies. Sensitivity and subgroup analyses were performed to identify the source of heterogeneities and to compare the prevalence estimates across the groups. The Joanna Briggs Institute's quality assessment checklist was used to evaluate the quality of the included studies. Cochran's Q and the I2 tests were used to assess heterogeneity between the studies. RESULTS: A total of ten studies were included for the final analysis, with 2642 adolescents living with HIV/AIDS. Our final meta-analysis showed that more than a quarter of adolescents with HIV had depression [26.07% (95% CI 18.92-34.78)]. The prevalence was highest amongst female adolescents (32.15%) than males (25.07%) as well as amongst the older adolescents aged 15-19 years (37.09%) than younger adolescents aged 10-14 years (29.82%). CONCLUSION: Our study shows that a significant proportion of adolescents with HIV had depression, indicating the imperativeness of intervention strategies to alleviate the suffering and possibly reduce the probable negative ramifications.

Magnitude and associated factors of poor medication adherence among diabetic and hypertensive patients visiting public health facilities in Ethiopia during the COVID-19 pandemic.

OBJECTIVE: This study aims to assess the magnitude and associated factors of poor medication adherence among diabetic and hypertensive patients visiting public health facilities in Addis Ababa, Ethiopia during the COVID-19 pandemic. METHODS: A multi-site cross-sectional design was conducted from 1st through 30th of August 2020 at public health facilities of the study area. Adult outpatients with T2DM and hypertension visiting hospitals and health centers were included in the study. A proportion to size allocation method was used to determine the required sample size per facility. Data was collected using the 8-item Morisky medication adherence scale. Descriptive statistics and binary logistic regression were used to analyze data. A 95% confidence interval and p≤0.05 statistical significance was considered to determine factors associated with poor medication adherence. RESULTS: A total of 409 patients were included in the present study. About 57% of the patients reported that the COVID-19 pandemic has posed negative impacts on either of their follow-up visits, availability of medications, or affordability of prices. And, 21% have reported that they have been affected in all aspects. The overall magnitude of poor medication adherence was 72%. Patients with extreme poverty were more likely to have good medication adherence (AOR: 0.59; 95%C.I: 0.36-0.97), whereas attendance to a health center (AOR: 1.71; 95%C.I: 1.02-2.85), presence of comorbidity (AOR: 2.05; 95%C.I: 1.13-3.71), and current substance use history (AOR: 11.57; 95%C.I: 1.52-88.05) predicted high odds of poor adherence. CONCLUSION: Over a three-fourth of the patients, in the study setting, have poor adherence to their anti-diabetic and antihypertensive medications. Health facility type, income level, comorbidity, and current substance use history showed a statistically significant association with poor adherence to medication. Stakeholders should set alternative strategies as perceived impacts of the COVID-19 pandemic on medication adherence are high in the study area.

The Global Prevalence of Suicidal Attempt among Medical Students: a Systematic Review and Meta-Analysis.

Even though suicidal attempt among medical students is a major public health concern, there are no prior studies that reported its consolidated magnitude worldwide. To the best of our knowledge, this systematic review is the first to quantitatively analyze the prevalence of suicidal attempts among medical students. We systematically searched PubMed, Embase, and Scopus for English language articles that assessed the prevalence of suicide attempts among medical students. A random-effect meta-analysis was used to combine data from individual studies. The heterogeneity across the studies was evaluated using Cochran's Q- and the I2 test. We assessed publication bias using Egger's test and visual inspection of the symmetry in funnel plots. A total of 14 articles were selected for meta-analysis according to the PRISMA guideline. The pooled lifetime prevalence of suicidal attempt was found to be 2.19% (95% CI; 1.17-4.07). The pooled one-year prevalence was estimated to be 1.64 (95% CI; 0.60-4.45). The estimated prevalence of suicidal attempt was considerably high among medical studies in low and middle-income countries than medical studies in high-income countries. The estimated prevalence of suicidal attempt also varies by gender of participants Given the high prevalence estimate of suicidal attempt among medical students and its potential in resulting death by suicide, early identification, and interventions should be considered among medical students.

A Systematic Review and Meta-Analysis of the Prevalence of Post-Traumatic Stress Disorder among Homeless People.

Post-traumatic stress disorder (PTSD) is common among homeless people and is associated with an increased risk of mortality from suicide, medical causes, and drug-related problems. However, there are no previous systematic review and meta-analysis studies that reported the consolidated magnitude of PTSD among homeless people. A literature search was conducted on PubMed, Embase, and Scopus to discover pertinent studies that determined the prevalence of PTSD among the homeless. Articles were evaluated by titles, abstracts, and full-text. Comprehensive meta-analysis software was used to conduct the meta-analysis. Subgroup and sensitivity analysis were performed and Cochran's Q- and the I2 test were used to assess heterogeneity. The evidence of publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots. From the total, 19 studies with 20,364 participants across seven countries were included in the final analysis. Our meta-analysis revealed that the pooled prevalence of PTSD among homeless people was 27.38% (95% CI; 21.95-33.57). In our subgroup analysis, we found that the prevalence of PTSD was considerably high as measured by the screening instrument (35.93%) than the diagnostic instrument (23.57% %). The prevalence of PTSD among homeless showed a significant variation by the location of the studies, the instruments used to measure PTSD as well as the quality of the included studies. This review showed that the pooled prevalence estimate of PTSD among homeless peoples was remarkably high (27.38%). Early screening and treatment of PTSD among homeless peoples are warranted to alleviate suffering.

Epidemiology of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents in Africa: a systematic review and meta-analysis.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is the most common neurodevelopmental disorders in childhood and adolescence, affecting 2.2 to 17.8% of all school-aged children and adolescents. ADHD in children has been associated with a wide range of developmental deficits including limitations of learning or control of executive functions as well as global impairments of social skills. However, no review has been conducted to report the consolidated magnitude of ADHD in children and adolescents in Africa. Therefore, this systematic review and meta-analysis aimed to estimate the prevalence of ADHD in Africa. METHODS: Following the PRISMA guideline, we systematically reviewed and meta-analyzed studies that investigated the prevalence of ADHD in Africa from three electronic databases (PubMed, Embase, and Scopus). We also looked at the reference lists of included studies to include other relevant studies. Subgroup and sensitivity analysis was carried out based on the study setting, tools used to measure ADHD, sex of participants, and the subtype of ADHD. Heterogeneity across the studies was evaluated using Cochran's Q- and the I 2-test. We assessed potential publication bias using Egger's test and visual inspection of the symmetry in funnel plots. RESULTS: In the present meta-analysis, 7452 articles were initially identified and evaluated. Of these, 12 studies that met the inclusion criteria were included in the final analysis. The pooled prevalence of ADHD in children and adolescents in Africa was 7.47% (95% CI 60-9.26). The prevalence of ADHD was apparently greater in boys (10.60%) than in girls (5.28%) with a male:female ratio of 2.01:1. In our subgroup analysis, the predominantly inattentive type (ADHD-I) was found to be the most common subtype of ADHD, followed by hyperactive-impulsive type (ADHD-HI) and the combined type (ADHD-C) with the prevalence of 2.95%, 2.77%, and 2.44% respectively. The predominantly inattentive type (ADHD-I) was the most common type of ADHD in both boys (4.05%) and girls (2.21%). The funnel plot and Egger's regression tests provided no evidence of substantial publication bias in the prevalence of ADHD. CONCLUSION: Our systematic review suggested a higher prevalence of ADHD (7.47%) in children and adolescents in Africa, indicating that ADHD is a serious public health problem in children and adolescents in Africa. The prevalence of ADHD was considerably greater in males than in females. The predominantly inattentive type (ADHD-I) was the most common type of ADHD in both males and females. Greater attention needs to be paid to the prevention and treatment of ADHD.

Suicidal Ideation and Attempt among Homeless People: a Systematic Review and Meta-Analysis.

Globally, suicide is a major public health problem among homeless people. Suicidal ideation and attempt are remarkably higher among homeless people as compared to the general population and they are linked with greater risk of complete suicide. However, no systematic review and meta-analysis has been conducted to report the consolidated magnitude of suicidal ideation and attempt among homeless people. We searched PubMed, Embase, and Scopus to identify pertinent studies on suicidal ideation and attempt among homeless people. A meta-analysis of the studies was conducted using a random effect model. We also conducted a sensitivity analysis and Cochran's Q- and the I2 test was employed to evaluate heterogeneity. Publication bias was assessed by Egger's test and visual inspection of the symmetry in funnel plots. In total, 20 eligible studies with 27,497 homeless people matched the inclusion criteria. Nineteen studies assessed suicidal attempt and thirteen studies assessed suicidal ideation among homeless people. The pooled current and lifetime prevalence of suicidal ideation was 17.83% (95% CI;10.73-28.14) and 41.60% (95% CI; 28.55-55.95), respectively whereas the pooled current and lifetime prevalence of suicidal attempt was 9.16% (95% CI;4.10-19.20) and 28.80% (95% CI; 21.66-37.18), respectively. We found a considerable heterogeneity between the studies, but we found no significant publication bias. The current review revealed a remarkably higher magnitude of suicidal ideation and attempt among homeless people as compared to the estimated prevalence in the general population. The concerned stakeholders need to give attention to address this problem emphasizing more on prevention and treatment strategies as well as utilizing holistic approaches to address the potential predictors of suicide among homeless people including physical, mental, and substance use problems.

The epidemiology of alcohol consumption in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Globally, excessive alcohol consumption is a major public health problem and is associated with social, mental, physical and legal consequences. However, no systematic review and meta-analysis has been performed to report the consolidated magnitude of alcohol consumption in Ethiopia. METHODS: PubMed, EMBASE, and SCOPUS were systematically searched to identify pertinent studies. Subgroup and sensitivity analysis was conducted and Cochran's Q- and the I2 test were used to assess heterogeneity. Publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots. RESULTS: We included 26 articles with a total of 42,811 participants. The pooled current and lifetime prevalence of alcohol consumption was 23.86% (95%CI; 17.53-31.60) and 44.16% (95%CI; 34.20-54.62), respectively. The pooled prevalence of hazardous alcohol consumption was 8.94% (95%CI; 3.40-21.50). The prevalence of hazardous alcohol consumption was remarkably higher in men (11.58%) than in women (1.21%). The prevalence of current and lifetime alcohol consumptions among university students were 22.08% & 38.88% respectively. The pooled data revealed that male sex was found to be a significant predictor of hazardous alcohol consumption (OR 10.38; 95%CI 3.86 to 27.88) as well as current (OR 2.45; 95%CI 1.78 to 3.38) and lifetime (OR 2.14; 95%CI 1.39 to 3.29) consumption. The magnitude of alcohol consumption among university students was apparently lower than the magnitude in other population of the country. The current study suggested a remarkable recent increment in the magnitude of hazardous alcohol consumption in Ethiopia. CONCLUSION: The current study revealed that the prevalence of alcohol consumption in Ethiopia is comparable with the global estimates of alcohol consumption from the World Health Organization (WHO). The prevalence of hazardous alcohol consumption was remarkably higher in men (11.58%) than in women (1.21%). Male sex was found to be a significant predictor of alcohol consumption. The present study also suggested considerable recent increment in the magnitude of hazardous alcohol consumption in Ethiopia.

Epidemiology of khat (Catha edulis) consumption among university students: a meta-analysis.

BACKGROUND: Khat is amphetamine-like substance commonly consumed by students when they wish to study for long hours especially during examination periods. Khat consumption is associated with increased rates of cardiovascular problems, stroke, myocardial infarction, cardiomyopathy, periodontal disease, gastritis, poor oral hygiene, psychosis, decreased quality of life, and poor academic performance. METHODS: PubMed, EMBASE, and SCOPUS were systematically searched without restriction by publication status. Publications were screened according to predefined inclusion criteria. Twenty-five articles were included. Random effect model was used to calculate weighted prevalence, odds ratio (OR) and corresponding 95% confidence interval (CI). We assessed the risk of publication bias by using funnel plot and Eggers's regression tests. RESULTS: The pooled prevalence of current khat use among university students was 14.16% (95% CI; 11.87-16.81). The pooled prevalence of current khat use was highest in Saudi Arabia 18.85% and it was 13.59% in Ethiopia and 13.04% in Yemen. In addition, the current pooled prevalence of khat use was higher in men at 19.26% than in women 6.41%. Regarding lifetime khat use, in this study, the pooled prevalence of lifetime khat use was 27.31%. The lifetime prevalence was higher in men at 31.47% than in women 11.79%. Moreover, the lifetime prevalence of khat use was 43.27% in Yemen, 37.32% in Saudi Arabia, and 24.82% in Ethiopia. We found significantly increased odds of current (OR 3.59; 95%CI 2.01-6.41) as well as lifetime (OR 3.48; 95%CI 2.09-5.78) khat chewing in men as compared to women. CONCLUSION: The pooled prevalence of current and lifetime khat consumption was 14.16 and 27.31%, respectively. Both the current and lifetime prevalence of khat use was higher in men than in women. In addition, both the current and lifetime prevalence estimates of khat consumption were low in Ethiopia than in Saudi Arabia. Moreover, the odds of both current and lifetime khat consumption were higher in male students than in female students. Programmes that specifically aim at increasing awareness and that most motivate reduced khat consumption among university students were recommended.

A systematic review and meta-analysis of epidemiology of depression in people living with HIV in east Africa.

BACKGROUND: Depression is the most prevalent psychiatric disorder among people living with HIV (PLWHIV) and is associated with poor quality of life, additional comorbidities, disability, unemployment, poorer therapeutic outcomes and risky behaviors. The present systematic review and meta-analysis aims to systematically summarize empirical evidence and to formulate recommendations for future research. METHODS: We searched PubMed, EMBASE, SCOPUS, and relevant literature for possible studies to include. A qualitative and quantitative analysis was undertaken for this systematic review. Subgroup and sensitivity analysis were performed. Cochran's Q- and the I2 test were used to assess heterogeneity. The presence of publication bias was evaluated by using Egger's test and visual inspection of the symmetry in funnel plots. RESULTS: Of 283 titles initially identified, 81 abstracts were eligible for review. Of these, 46 articles qualified for full text review and 19 were retained. In our meta-analysis the pooled prevalence of depression in PLWHIV was 38% (95% CI 29.30-47.54). The pooled prevalence estimates of depression was 49.79% in Ethiopia and 30.88% in Uganda. In addition, the prevalence of depression was 12.40% and 46% as measured by diagnostic and screening instrument respectively. Our qualitative synthesis showed that factors such as having opportunistic infection, perceived stigma, negative life event, WHO clinical staging of disease, hospitalization in the past one month, stressful life events, food insecurity, self-efficacy, missed frequency of clinic visit, frequency of follow-up, older age, low income, urban residence and being government employee were strongly and significantly associated with depression in PLWHIV in east Africa. CONCLUSION: The pooled prevalence estimates of prevalence of depression in PLWHIV was 38%. The prevalence estimates of depression in PLWHIV in Ethiopia was significantly higher than Uganda. In addition the prevalence of depression was significantly higher in studies conducted by screening than diagnostic instrument. Routine screening and integrated management of depression into the existing HIV care services is warranted. Validation and use of standard instrument to assess depression in PLWHIV is needed. Moreover, longitudinal and community based studies focusing on incidence and determinates of depression in PLWHIV are recommended.
