Prevalence and predictors of khat chewing among Ethiopian university students: A systematic review and meta-analysis

Levels and Health Risk Assessments of Heavy Metals in Khat and Its Support Soil in Algesachi, Ilu Ababor, Ethiopia

Background

Khat (Catha edulis Forsk) is a stimulant plant grown in East Africa and the Arabian Peninsula. Heavy metal pollution has been a global concern due to its acute and chronic health effects and the major route of exposure is the consumption of contaminated foods. In this study, the determination and health risk assessment of heavy metals (Mn, Cu, Zn, Ni, Cr, Cd, and Pb) in khat and its support soil samples was carried out.

Materials and Methods

Khat and its support soil were analyzed for the levels of 7 toxic heavy metals by Atomic Absorption Spectrophotometer. Samples were randomly collected from 3 districts of khat farming kebeles and digested using mixture of strong acids.

Results

The concentrations (mg/kg) of analytes in soil and khat samples were: Cu (6.78-35.80); Zn (24.30-199.02); Mn (7.59-1855.40); Ni (6.37-64.80); Cr (0.82-169.20); Cd (14.2-38.8), and Pb (ND). Among the analyzed heavy metals in soil, Mn was with the highest concentration, followed by Zn, Cr, Cu, Ni, and Cd while that of Zn was the maximum followed by Cu, Mn, and Cr in khat. The levels of Zn, Cr, and Cd in soil samples from all study sites and detected concentrations of Cr in khat samples exceeded the recommended FAO/WHO levels.

Conclusion

The hazard index (HI) of metals in khat from study areas was less than 1 indicating a less likelihood of non-carcinogenic toxicological health effects. However, the presence of these toxic chemicals in soil and khat indicates product contamination and needs extensive further investigation involving other heavy metals.

Child sexual abuse and its determinants among children in Addis Ababa Ethiopia: Systematic review and meta-analysis

Child sexual abuse is a significant public health concern and a breach of basic human rights affecting millions of children each year globally. It is typically not reported by victims, hence it remains usually concealed. Except for single studies with varying reports, there is no national studies conducted on child sexual abuse in Ethiopia. Therefore, this review determined the pooled magnitude and determinants of sexual abuse among children in Ethiopia. Potential articles were searched from PubMed, Science Direct, Scopus, and Web of science using relevant searching key terms. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to evaluate the quality of all selected articles. Data were analyzed using STATA Version 14 software. Publication bias was checked using Egger's test and funnel plot. Cochran's chi-squared test and I2 values were used to assess heterogeneity. A random-effects model was applied during meta-analysis. The pooled prevalence of sexual abuse among 5,979 children in Ethiopia was 41.15% (95% CI: 24.44, 57.86). Sex of children (OR: 2.14, 95%CI: 1.12, 4.06), smoking (OR: 4.48, 95%CI: 1.26, 76.79), khat chewing (OR: 3.68, 95%CI: 1.62, 21.93), and alcohol use (OR: 4.77, 95%CI: 2.22, 10.25) were the determinants of child sexual abuse. The main perpetrators of sexual abuse against children were neighbors, boy/girlfriends, family members, school teachers, and stranger person. Child sexual abuse commonly took place in the victim's or perpetrator's home, school, and neighbor's home. This review revealed that the magnitude of child sexual abuse in Ethiopia was relatively high and multiple factors determined the likelihood of sexual violence against children. Thus, policy-makers and concerned stakeholders should strengthen comprehensive sexual and reproductive health education to reduce the magnitude and consequences of child sexual abuse. Moreover, support with special attention should be given to children with mental illness and physical disabilities.

Khat chewing among parents and their children: A potential transgenerational effect

Background

Khat has a stimulating and addictive effect and can induce consequences on the health and socioeconomic status of khat chewers.

Objectives

This study aims to assess knowledge, attitude, and practice of khat chewing among parents in Jazan and its consequential effect on their children.

Methods

This cross-sectional investigation was conducted in the Jazan region of Saudi Arabia. Data was collected via a web-based, self-administered questionnaire measuring demographics, knowledge, attitudes, and practices concerning khat chewing. The Chi-square test or Fisher's exact test was used to assess factors associated with khat chewing among parents and its consequential effect on their children.

Results

A total of 724 parents were included. The sample had an overall good knowledge about the health hazards of khat chewing and an attitude against khat chewing. Nonetheless, the number of parents who reported that they had ever tried khat chewing was 200 (27.6%) and 106 parents (14.6%) confirmed that their children were khat chewers. Additionally, 98 (13.5%) parents declared that they practiced khat chewing in front of their children. Higher frequencies of parents who reported providing khat to their children were identified among parents with higher attitude levels that favor khat chewing (P value = 0.04).

Conclusions

Efforts should be made to develop targeted preventive and educational strategies to reduce khat chewing among parents who have favorable attitudes toward khat chewing.

Exploring the perception of key stakeholders toward khat policy approaches in Ethiopia: a qualitative study

BACKGROUND

Khat is an amphetamine-like plant, produced and commonly chewed in Ethiopia by a large group of the population. Although significant multidimensional harms of khat use have been reported, currently, there are no policies or organized activities against khat use in Ethiopia. Therefore, the current study aimed to explore the perception of key stakeholders toward khat policy approaches for Ethiopia.

METHODS

A qualitative study was conducted using focus group discussion (FGD) and in-depth interview (IDI). Ten stakeholders participated in the IDIs, and another 15 individuals participated in the FGDs. Key stakeholders were appropriately mapped and purposively selected based on their experience related to khat use and khat harm reduction. Interviews and FGDs were led by the study authors and were audio-recorded. The audio-recorded data were transcribed verbatim and then translated into English language. The data were analyzed using thematic analysis approach.

RESULTS

Participants preferred prevention and law regulation measures for khat policy approaches for Ethiopia. Proposed prevention and law regulation measures included regulating the transportation of khat, limiting the minimum age to buy and sell khat, prohibiting khat use at some public places, banning khat advertising and promotion, and imposing excise tax. Individual level khat harm reduction strategies were also proposed to be useful. However, the participants asserted that total khat ban in Ethiopia is not likely to be feasible and acceptable.

CONCLUSION

Prevention, treatment or care for individuals with problematic khat use, law regulation, and harm reduction were preferred approaches by stakeholders for khat policy in Ethiopia instead of total banning.

Polydrug Use among Students in a Public University in a Lower Middle-Income Country

Recreational drug use among students in tertiary institutions remains a public health concern. Despite documentation of drug use in Kenyan universities, most of the studies are based on self-reported history which is prone to social desirability bias. It is in this context that we sought to establish lifetime and current drug use among university students. The study investigated self-reported and confirmed drug use. Using proportionate to size and snowball sampling methods, 380 respondents were enrolled from three university campuses. Actual drug use was confirmed qualitatively using a 6 panel plus alcohol saliva test kit. The study participants' median (IQR) age was 22 (20-23) years, and 262 (69%) were male; 328 (86%) were degree-level students, while 127 (33%) were in their fourth year and above. A total of 221 (58%) students reported a lifetime ever use of drugs, while 193 (51%) tested positive for at least one drug. Alcohol, tobacco products (cotinine), marijuana, and amphetamine or khat were the most preferred drugs. The usage was either solely, concurrently, or simultaneously. Having multiple sexual partners compared to students with no sexual partner (adjusted risk ratio (aRR) of 2.33 (95% CI 1.45, 3.76)) and residing in Mishomoroni and Kisauni (aRR 1.50 (95% CI 1.08, 2.09)) were associated with risk of testing positive for any drug. Having one (aRR of 1.54 (95% CI 1.05, 2.26)) and multiple sexual partners (aRR 2.03 (95% CI 1.27, 3.25) and residing in Mishomoroni and Kisauni (aRR 1.48 (95% CI 1.05, 2.08)) were associated with self-reported drug use. One out of two students was currently using drugs. Irrespective of the method used to record data, alcohol, tobacco products, marijuana, and amphetamine or khat were the most preferred drugs. The usage was solely, concurrently, or simultaneously. Future interventions should focus on continuing students, students' residences, and those who are sexually active.

Understanding the Mechanisms of Action and Effects of Drugs of Abuse

AIM

Drug abuse and addiction are major public health concerns, with millions of people worldwide affected by the negative consequences of drug use. To better understand this complex issue, a review was conducted to examine the mechanisms of action and effects of drugs of abuse, including their acute and chronic effects, the symptoms of abstinence syndrome, as well as their cardiovascular impacts.

METHODS

The analyzed data were obtained after surveying an electronic database, namely PubMed, with no time limit, grey literature sources, and reference lists of relevant articles.

RESULTS

The review highlights the different categories of drugs of abuse, such as opioids, stimulants, depressants, hallucinogens, and cannabis, and discusses the specific ways that each drug affects the brain and body. Additionally, the review explores the short-term and long-term effects of drug abuse on the body and mind, including changes in brain structure and function, physical health problems, and mental health issues, such as depression and anxiety. In addition, the review explores the effects of drug abuse on cardiovascular health, focusing on electrocardiogram changes. Moreover, the analysis of relevant literature also highlighted possible genetic susceptibility in various addictions. Furthermore, the review delves into the withdrawal symptoms that occur when someone stops using drugs of abuse after a period of chronic use.

CONCLUSION

Overall, this review provides a comprehensive overview of the current state of knowledge on drug abuse and addiction. The findings of this review can inform the development of evidence-based prevention and intervention strategies to address this critical public health issue.

Prevalence and Risk Factors of Hypertension in Hargeisa, Somaliland: A Hospital-Based Cross-Sectional Study

Hypertension is the leading risk factor for cardiovascular diseases and represents a major public health challenge worldwide. There is a paucity of information regarding the hypertension status of adults in Somaliland. We aimed to assess the magnitude of, and factors associated with, hypertension among adult patients seeking care at Hargeisa group hospital in Hargeisa city, Somaliland. We conducted a health facility-based cross-sectional study enrolling adult outpatients. We used the World Health Organization (WHO) STEPwise surveillance approach to obtain patient information. A total of 319 participants (54.2% males; mean age 40.4 ± 14.0 years) had complete data records. The prevalence of hypertension was 22.6% (95% confidence interval; 18.2-27.6%). The prevalence of hypertension increased with age and was higher in males (24.9%) than in females (19.9%). Age, cholesterolaemia and obesity were significantly associated with hypertension. Separate analyses for females and males revealed that obesity was significantly associated with hypertension in females but not in males. On the contrary, cholesterolaemia was significantly associated with hypertension in males but not in females. We found a high prevalence of hypertension and multiple risk factors for non-communicable diseases (NCDs) in outpatients seeking care in Hargeisa. Our findings emphasise the need for enhanced focus on the prevention and management of NCDs in Somaliland.

Current alcohol, tobacco, and khat use and associated factors among adults living in Harari regional state, eastern Ethiopia: A community-based cross-sectional study

Background

Psychoactive substance use becomes a major public health and socioeconomic problem worldwide. Despite its burden and consequences, there is no community-based study conducted on psychoactive substance use and associated factors in eastern Ethiopia. Therefore, this study aimed to assess the magnitude and determinants of current alcohol, tobacco, and khat among adults living in Harari regional state, eastern Ethiopia.

Methods

A community-based cross-sectional study was conducted on 955 adults living in Harari regional state. Participants were randomly recruited using a simple random sampling technique. Data were collected by interviewer-administered structured and semi-structured questionnaires. Data were entered into Epi Data version 3.1 and exported to Stata version 14.0 for analysis. Logistic regression analysis was performed to determine the association between the outcome and independent variables, and the statistical significance was declared at a p < 0.5.

Results

Of 955 eligible participants, 95.29% participated in the study. The overall prevalence of current alcohol use, tobacco use, and khat use in this study was 8.24, 14.5, and 63.30%, respectively. The availability of alcohol, being unemployed, and being a current khat user were significantly associated with current alcohol use. Being male, having a low level of education, having peer pressure, having a common mental disorder, being a current alcohol user, and being a khat user were identified as significant predictors for current tobacco use. The age between 31 and 40 years, being a Muslim religion follower, being a farmer, being a current tobacco user, and availability of khat were significantly associated with current khat use.

Conclusion and recommendations

The prevalence of psychoactive substance use in the study area was relatively high compared with that of previous studies. By considering these determinants, screening, early identification, and developing appropriate intervention strategies to prevent and tackle current alcohol, tobacco, and khat use in the community should be of great concern.

Substance use and substance use disorders in Africa: An epidemiological approach to the review of existing literature

The relationship between man and substances that have abuse potentials, and whose use has been associated with the development or progression of substance use disorders has continued to evolve in terms of geography, economic implications, and time. History shows that local plants with psychoactive constituents can get exported worldwide through global travel, commerce, or even conquest. Time and globalization also change people’s relationship with substances of abuse; hence, an area that was initially alien to certain substances might evolve to becoming a trafficking hub, and then a destination. A case in point is Africa where a rapidly increasing prevalence of substance use/abuse and substance use disorder among adolescents and young adults is putting enormous strain on the economy, healthcare system, and society at large. However, there appears to be a paucity of scientific literature and data on the epidemiology, risk assessment, and contributing factors to substance use and the development of substance use disorders across Africa. In this narrative review, we examine extant literature (PubMed, Google scholar, Medline) for information on the prevalence, trends, and influencers of substance use and the development of substance use disorders. This is with a view of understanding the determinants of substance use and factors that influence the development of substance use disorders in the region, and how this information can be channeled towards developing a comprehensive intervention and treatment program.

Abuse Potential of Cathinones in Humans: A Systematic Review

Introduction and objective: Assessing the abuse potential of new substances with central nervous system activity is essential for preventing possible risks of misuse and addiction. The same methodology is recommended for the evaluation of the abuse potential of recreational drugs. This systematic review aims to assess the pharmacological effects related to the abuse potential and pharmacokinetics of cathinones, which are evaluated in both experimental and prospective observational studies in humans. Materials and Methods: A systematic search of the published literature was conducted to retrieve studies that had administered cathinone, mephedrone, methylone, and diethylpropion to evaluate their acute pharmacological effects related to abuse potential. Results: The search yielded 583 results, 18 of which were included to assess the abuse potential of cathinone (n = 5), mephedrone (n = 7), methylone (n = 1), and diethylpropion (n = 5). All four substances induce stimulant and euphorigenic effects that resemble those of amphetamines and MDMA, and their different intensities may be associated with varying levels of abuse potential. Conclusions: Cathinone, mephedrone, methylone, and diethylpropion induce a range of desirable and reinforcing effects that may, to some extent, result in abuse potential. Further investigation is needed to minimize and prevent their impact on society and public health.

A systematic review on risk factors for khat chewing among adolescents in the African continent and Arabian Peninsula

Introduction

Khat is a flowering plant with stimulant effect on the nervous system and produce psychological dependence. Despite its harmful effects, the ingestion of khat has been part of cultural norms and the legality of khat varies by region.

Objective

This systematic review aimed at critically evaluating the available evidence on the risk factors of khat chewing among adolescents.

Methods

A systematic review was conducted on published research studies from five databases Scopus, PubMed, Science-direct, Ovid and google scholar using keywords khat chewing OR qat chewing AND associated factors OR risk factors OR contributing factors AND adolescents OR teenagers. Articles included were either cross-sectional, cohort, case-control or qualitative studies which were published between the year 1990 till present. Excluded articles were the non-English written articles, descriptive studies and irrelevant topics being studied.

Results

Out of 2617 records identified and screened, six were included for the analysis and interpretation of the data. All included studies were cross-sectional study design. All six studies reported having family members who chewed khat significantly predict khat chewing among adolescents, followed by five articles for friends or peers who also chewed khat and four articles for male gender. Smoking was also found to have the highest odds (OR = 18.2; 95% CI: 12.95–25.72) for khat chewing among adolescents.

Conclusion

The review highlights the crucial role of family members, friends or peers and male gender to predict khat chewing among adolescents. Effectiveness of health promotion programs to educate and reduce khat chewing among adolescents will require active participation of family members and friends.

Khat Chewing and Lipid Profile in Human and Experimental Animals

BACKGROUND

Catha edulis, also known as khat or qat, is a plant that grows in East Africa and southern Arabia. Several millions of people chew the leaves and twigs of khat plant for their central stimulating amphetamine-like effects. Khat chewing is becoming more common in Europe and the United States, owing to worldwide migration.

OBJECTIVE

This review examines the khat ingredients, global prevalence, and legal status as well as its effects on lipid profile. Methodology. A literature search was performed using PubMed, Scopus, and Google Scholar to collect information within articles published up to April 2021 with the goal of identifying relevant studies. The proposed mechanisms of cathinone effects on total cholesterol and triglyceride were also discussed.

CONCLUSION

The khat chewing habit is considered as a serious economic and health issue that needs specialized programs to assist those people to quit or reducing this habit.

Prevalence and Associated Factors of Common Mental Disorders Among Adult Residents in Silte Zone, Southern Ethiopia

INTRODUCTION

Mental health problems appear to be increasing in importance in Africa. Mental and substance use disorders were the leading cause of yearly lived with disability in Sub-Saharan Africa. Evidence from previous studies shows considerable variation in the prevalence of these disorders. The most acceptable explanation for this wide variation is likely to be the fact that socio cultural factors are major determinants of mental disorders. Therefore a mental disorder has to be understood in a specific setting to develop effective and tailored interventions.

OBJECTIVE

The objective of this study was to determine the prevalence and associated factors of common mental disorders among adult residents in Silte Zone, southern Ethiopia.

METHODS

Community based cross-sectional study was conducted in the study area. A total of 1178 adults were selected by using a three-stage systematic sampling technique. The Self-Reporting Questionnaire (SRQ-20) was used to determine the prevalence of common mental disorders. Data were analyzed by using SPSS version 20. Both bivariate and multiple logistic regression analyses were employed to identify factors associated with common mental disorders.

RESULTS

The prevalence of common mental disorders among adults found to be 39.7%. Increased age (OR = 1.114; 95% CI = 1.095, 1.134), being female (OR = 9.421; 95% CI = 5.947, 14.926), poor social support (OR = 1.987; 95% CI = 1.358, 2.907) and having life threatening experience (OR = 2.162; 95% CI = 1.825, 2.562) were significantly associated with common mental disorders.

CONCLUSION

In the study, the magnitude of common mental disorders remains high in the study area. Increased age, being female, poor social support and having life-threatening experience were significantly associated with common mental disorders.

Current Substances Use Among Students in Ethiopia: A Systematic Review and Meta-Analysis of 20-Years Evidence

BACKGROUND

The use of psychoactive substances is one of the main public health issues worldwide. However, there is a lack of evidence on the magnitude of current substance use among students in Ethiopia. Therefore, this study aimed to provide comprehensive views of the current prevalence of substance use among students in Ethiopia.

METHODS

We searched PubMed/Medline, Health InterNetwork Access to Research Initiative (HINARI), Google Scholar, and gray literature sources between 2000 and 2019. The prevalence of current substances with a 95% confidence interval (CI) was estimated using the random-effects model. The results were presented using forest plots, and Cochrane Q-test and I 2 were used to measure the extents of between-study variations.

RESULTS

A total of 1543 study articles were identified from electronic databases, and 32 cross-sectional studies were included in the meta-analysis. The prevalence of current use of at least 1 substance was 37.63% (95% CI: 33.66, 41.69), alcohol 27.61% (95% CI: 22.10, 33.48), khat 17.20% (95% CI: 14.03, 20.62), and smoking 9.74% (95% CI: 7.17, 12.64). The prevalence of any substance use in high school students versus university/college students was 41.55% (95% CI: 38.83, 44.29) versus 36.24% (95% CI: 32.37, 40.20), alcohol 24.21% (95% CI: 14.05, 36.11) versus 25.27% (95% CI: 19.76, 31.20), khat 13.82% (95% CI: 8.61, 20.02) versus 17.30% (95% CI:13.75, 21.16), and cigarette 8.30% (95% CI: 1.89, 18.60) versus 9.80% (95% CI: 7.32, 12.58). Meta-regression analysis revealed publication year, sample size, female proportion, and age were not significantly associated with the current use of substances.

CONCLUSION

Overall, the current substance use of any substance, alcohol, chewing khat, and smoking cigarettes was relatively high. A significant proportion of high school students were already using substances at an early age. Policymakers should formulate and implement regulations to control the pervasive use of substances by young people around educational institutions at all levels.

PROTOCOL REGISTRATION

The protocol has been registered on 19 August 2019 on the International Prospective Register of Systematic Reviews (PROSPERO) with ID: CDR42019130560.

Physical fighting among adolescents in eastern Ethiopia: a cross-sectional study

Background

Physical fights have been a common health problem among adolescents, and approximately a million adolescents’ lives are lost due to violence-related incidents worldwide. There is a lack of information on the burden of adolescents’ physical fights in eastern Ethiopia. Hence, the study aims to estimate the magnitude and assess factors associated with physical attacks and fighting among adolescents in eastern Ethiopia.

Methods

A community-based cross-sectional study was conducted among 2424 adolescents in eastern Ethiopia in 2016. Simple random sampling was used to recruit study participants. Data were collected by trained interviewers using a structured questionnaire developed by the Africa Research, Implementation Science and Education (ARISE) network and adapted from the World Health Organization Global school-based student health survey. Descriptive statistics, binary and multivariable logistic regression were performed. Statistical associations were determined using adjusted odds ratio (AOR) at 95% Confidence Intervals (95% CIs) and P-value < 0.05.

Results

Prevalence of physical attacks and physical fights was 5.8%, and 26.4%, respectively. Adolescents who attended school (AOR 0.4, 95% CI: 0.2–0.9) and who chewed Khat (AOR 0.4, 95% CI: 0.2–0.8) were less likely to experience physical attacks. Male adolescents were two times more likely to engage in physical fights than female adolescents (AOR 2.4, 95% CI: 1.8–3.2). In-school adolescents who attended secondary (AOR 0.4, 95% CI: 0.2–0.7) or tertiary level of education (AOR 0.2, 95% CI: 0.1–0.7) were less likely to participate in physical fighting than those with primary level education. Adolescents who had ever engaged in physical work to earn money for food or drink were 1.9 times more likely to be physically attacked compared to those who had not (AOR 1.9, 95% CI: 1.0–3.5).

Conclusion

Physical attacks and fights were found to be common experiences of adolescents in eastern Ethiopia. Future research and programs should emphasize preventive health programs for reducing violence and promoting school enrolment and retention.

Prevalence and risk factors of psychoactive substance abuse among students in Ethiopia: A systematic review and meta-analysis

Background

Substance uses were seen in 18–25 years old age groups who are more than 40% world population, from which Africa was the region with the highest proportion accounting 60% in 2016. This review aimed to assess the burden of substance abuse among students in Ethiopia.

Methods

A comprehensive search was conducted in PubMed/Medline; Science direct and African Online Journal without language and date restriction.

Khat Use Patterns, Associated Features, and Psychological Problems in a Khat-Treatment-Seeking Student Sample of Jimma University, Southwestern Ethiopia

Background: Khat (Catha edulis) is a traditionally used substance in African and Arab countries that contains the amphetamine-like alkaloid cathinone. Khat use among Ethiopian students is a growing concern. This study aims to describe khat use, psychological problems, and motivation to change and to determine associated factors of khat use among students from Jimma University seeking psychological assistance.

Methods: In a cross-sectional study, a sample of 717 students from Jimma University, southwestern Ethiopia, who seek assistance to reduce khat use were recruited. The study used Amharic and Afaan Oromoo language versions of common psychological instruments and employed them as part of a comprehensive tablet computer-delivered self-report assessment battery, comprising the SRQ-20, the PCL-5, the LEC-5, the AUDIT, and the SOCRATES-khat. In addition, socio-demographic, economic variables, and functioning problems due to severe mental disorders were assessed. The analysis relied on the data of the 575 included participants and used clinical cut-off values to describe this treatment-seeking sample and hierarchical regression models to determine variables associated with khat use.

Results: The sample showed high khat use in the past month (M = 31.55 bundles, SD = 28.53, on M = 15.11 days, SD = 8.54); 17.0% showed highly problematic use. The sample was extremely burdened with comorbid psychiatric problems: 21.6% reported functioning problems due to past mental disorders, 60.2% scored above the cut-off for current common mental disorders, 37.9% screened positive for PTSD, and 47.1% reported hazardous alcohol use. Small to medium intercorrelations between variables were detected, and in hierarchical regression models, higher motivation to change khat use was associated with higher use of the substance.

Conclusions: This study clearly shows the need to develop research instruments, screening methods, and assistance services for khat-using students at Jimma University. Study participants' high mental health burden shows the need for targeted intervention programs that go beyond brief interventions for khat use. Furthermore, the study highlights challenges for implementing such services: the barriers to utilization for females and khat users without comorbid mental health problems.

Barriers and Facilitators for Implementing Mental Health Services into the Ethiopian Health Extension Program: A Qualitative Study

PURPOSE

The Ethiopian Ministry of Health has integrated mental health services into the community health service, but it has not yet been implemented. Therefore, this study aimed to explore the barriers and facilitators of mental health service implementation in the Ethiopian community health program.

METHODS

A qualitative case study was conducted in the Ethiopian primary health care system in 2019. We have conducted about eight key informant interviews with policymakers, service managers, and service providers. The interviews were tape-recorded, transcribed, translated, and analyzed manually using the World Health Organization building blocks framework.

RESULTS

The Health Ministry of Ethiopia has recently included mental health services into the health extension package but not yet implemented as part of integrated services. The identified barriers were low political commitment, shortage of resources, non-functional referral system, lack of interest from private health service organizations, attitudinal problems from both the society and service providers, and lack of consistent reporting system of the mental health problems. However, the well-designed primary health care system, trained health extension workers, changing political commitment and attitude of the community could facilitate the mental health service implementation.

CONCLUSION

A series of activities are expected, especially from the healthcare system managers to implement, follow, and evaluate mental health services implementation at the health extension programs.

Seven in every ten khat chewers in Gondar City had an intention to stop khat chewing: cross-sectional study using Transtheoretical Model

BACKGROUND

Khat chewing practice is rapidly expanding worldwide and currently, an estimated over 10 million people chew khat daily. The transtheoretical model explains how behavior change occurs across the stages of change. So, this study aimed at assessing the intention to stop khat chewing and associated factors among khat chewers in Gondar City, northwest Ethiopia.

METHODS

Community-based cross-sectional study was conducted from March to April 2019 in Gondar City, northwest Ethiopia. Six hundred five khat chewers participated in the study from six randomly selected kebeles. The data were collected using structured and interviewer-administered questionnaire. Bivariate and multiple logistic regression models were fitted. Adjusted Odds ratio (AOR) with 95% confidence interval (CI) and p-values less than 0.05 were used to declare a significant association.

RESULTS

Of the study participants, 69.3% (95% CI: 65.8-72.9) had the intention to stop khat chewing within 6 months or before. The majority of the participants (55.4%) were at the contemplation stage. Higher self-reevaluation [AOR = 2.8, (95%CI: 1.6-5.0)], environmental reevaluation [AOR = 1.9, (95%CI: 1.1-3.3)] and social liberation [AOR = 1.8, (95% CI: 1.0-3.1)] were associated with intention to quit khat chewing. In addition, using additional substances daily, khat dependency, and early age initiation of khat chewing were associated with lower intention to quit khat chewing.

CONCLUSION

The majority of the khat chewers had the intention to quit khat chewing. Increased self-reevaluation, environmental reevaluation, and social liberation process of changes were associated with enhanced intention of quitting khat chewing. Thus, stage-based interventions should be done to inspire khat chewers to realize their motivation of stopping khat chewing.

The impact of protective psychosocial factors on khat chewing among male medical and dental future health-care providers in Yemen

BACKGROUND/PURPOSE

Khat chewing, a green leaf with amphetamine effects, is a public health concern. Yet, it is prevalent and evident, in the khat belt region, among male students in health faculties. This study aimed to examine whether psychosocial factors have a protective impact on khat chewing among male dental and medical students.

MATERIALS AND METHODS

A cross-sectional study included all students (1457) in second year and above at a Yemeni university. A self-administered questionnaire was used to obtain sociodemographic data and to assess students' psychosocial characteristics namely, depression, resilience and social support (perceived or received [living with or away from family]). Data analysis included descriptive statistics and multivariable logistic regression modelling.

RESULTS

The response rate was 61% (male = 334, female = 547) and the responding students' mean ± SD age was 22.95 ± 1.56 years. Of the respondents 185 (21% [95%CI = 18%-24%]) were current khat chewers (7 [4%] females and 178 [96%] males respectively). In the adjusted model, among male students living away from family was significantly associated with khat chewing (adjusted odd ratio [AOR] = 3.15,95%CI = 1.96-5.07, p < 0.001) and perceived social support was inversely significantly related to khat chewing (AOR = 0.98; 95%CI = 0.96-1.00; p = 0.019).

CONCLUSION

Within the limitation of the study of a single institute, social support whether received (living with family) or perceived appeared to be a protective factor from khat chewing among male medical and dental students. Social support should be enhanced and targeted to discourage khat chewing during the preparation of this future health care force.

Spatial Distribution and Factors Associated with Khat Chewing among Adult Males 15-59 Years in Ethiopia Using a Secondary Analysis of Ethiopian Demographic and Health Survey 2016: Spatial and Multilevel Analysis

Background

Khat chewing has become prevalent in the world due to the improvement of road and air transportation. In Ethiopia, khat chewing is more prevalent and widely practiced by men. Khat has a negative effect on social, economic, and mental health. There is variation in khat cultivation, use, and factors that associated with khat chewing in the Ethiopian regions. Therefore, this study is aimed at showing spatial distribution and factors associated with khat chewing among male adults 15-59 years in Ethiopia.

Methods

A total of 12,594 men were included in this study. ArcGIS version 10.7 software was used to show the spatial distribution of chewing khat among adult men in Ethiopia. The Bernoulli model was applied using Kilduff SaTScan version 9.6 software to identify significant purely spatial clusters for chewing khat in Ethiopia. A multilevel logistic regression model was fitted to identify factors associated with khat chewing. A P value < 0.05 was taken to declare statistically significant predictors.

Results

The EDHS 2016 survey showed that the high proportion of chewing khat was found in Dire Dawa, Harari, Southern Oromia, Somali, and Benishangul Gumuz regions. In spatial scan statistics analysis, a total of 126 clusters (LLR = 946.60, P value < 0.001) were identified. Age group 30-44 years old (AOR = 1.60, 95% CI: 1.37, 1.86) and 45-59 years old (AOR = 1.33, 95% CI: 1.09, 1.61), being single (AOR = 1.86, 95% CI: 1.64, 2.12), Muslim religion followers (AOR = 15.03, 95% CI: 11.90, 18.90), media exposed (AOR = 0.77, 95% CI: 0.68, 0.86), had work (AOR = 2.48, 95% CI: 2.08, 2.95), alcohol drinker (AOR = 3.75, 95% CI: 3.10, 4.53), and region (Afar, Amhara, Benishangul Gumuz, Gambela, Harari, Oromia, Somali, Southern Nations, Nationalities, and People's Region (SNNPR), and Tigray) and two cities (Addis Ababa and Dire Dawa) were statistically significant factors affecting chewing khat in Ethiopia.

Conclusions

In Ethiopia, the spatial distribution of khat chewing among adult men was nonrandom. A high proportion of khat chewing was observed in Dire Dawa, Harari, Southern Oromia, Somali, and Benishangul Gumuz regions. Older age group, being single marital status, alcohol drinker, media unexposed, had no work, and Muslim religion follower were factors affecting khat chewing. Policymakers should be given spatial attention in reducing the prevalence of chewing khat by teaching the health impact of khat chewing through media in the identified regions.

A qualitative exploration of substance misuse among homeless women in Addis Ababa, Ethiopia

BACKGROUND

Substance use among homeless people is higher compared to the general population. In some studies, reported rates of problematic drug use among the homeless vary, with estimates ranging from 25 to 70%. There is a common perception that substance abuse and homelessness are linked, but there is considerable debate about the direction of the relationship. Despite observations of high levels of substance use among the homeless population in Addis Ababa, there are limited studies to date conducted on the topic. This study aims to explore the factors associated with onset of substance use and its continued use, patterns of substance use and its social and health consequences among female residents of a shelter in Addis Ababa, Ethiopia.

METHODS

A qualitative study was conducted in 2019. In-depth interviews were conducted on 14 study participants who were selected purposively. The qualitative data analysis software QDA Miner 5.0.30 was used for data processing and analysis.

RESULTS

Four major thematic areas were identified and they comprised the categories under which sub-themes were identified and coded. The major segments or categories included the following: reasons for the onset of substance use after becoming homeless, experiences of substance use and reasons for continued use, the harms which resulted on them from substance use, and the means of obtaining supply of the substances.

CONCLUSION

Factors related to life on streets were strong reasons for onset of substance use, as well as for its continued use. Homeless women suffered untimely death, addiction, and ill health from use of substances; however, they gave priority to obtaining substances than any other thing, and used every means to grab a supply of the substances.

A Systematic Umbrella Review on the Epidemiology of Modifiable Health Influencing Factors and on Health Promoting Interventions Among University Students

Background: Universities represent an important setting for health promotion. The unique collective of university students is of particular relevance since they are the leaders, decision-makers, and parents of tomorrow. In this context, modifiable health influencing factors as well as interventions to prevent these, play a crucial role. Therefore, the present umbrella review aims to (i) provide an overview of review articles addressing epidemiological issues (prevalence and determinants) of modifiable health influencing factors in university students and (ii) to provide an overview of review articles addressing the evidence of interventions to promote/enhance modifiable health influencing factors in university students.

Methods: A systematic literature search was performed in the databases PubMed, Cochrane Reviews Library und Web of Science according to the PRISMA guidelines. Only systematic reviews and meta-analyses were included. The AMSTAR-2-Tool was used for the quality assessment.

Result: The initial search resulted in 10,726 records of which 81 fulfilled the inclusion criteria, with a further distinction in articles with an epidemiological focus (n = 39) and in articles with interventional approaches (n = 42). Topics of the different review articles ranged from physical activity over mental health, substance use, sleep, diet and nutrition, and media consumption. Many review articles had a specific focus on medical and nursing students and originated from the U.S.A., U.K., or China.

Discussion: This umbrella review provides an overview of review articles on the epidemiology of modifiable health influencing factors and on the evidence of interventions targeting these factors among university students. Thereby, experts as well as stakeholders in the field could gain insights into crucial target points for health promotion. It identifies research gaps in terms of study region and groups of students.

Prevalence and risk factors for khat use among youth students in Ethiopia: systematic review and meta-analysis, 2018

BACKGROUND

Khat use is a widely spreading public health problem affecting the most economically productive population areas in Ethiopia. Khat use among students has been linked with mental, physical, social, and psychological problems. Reliable prevalence has not been recognized because of varying published rates. The objective of this systematic review and meta-analysis is to synthesize evidence on the prevalence and potential risk factors of khat use in Ethiopia.

METHODS

We found 284 studies of which 266 were removed due to duplication, irrelevant topics, and other reasons, respectively. All studies conducted in Ethiopia on khat chewing among students irrespective of time frame were included. Subsequently, 18 studies were used for synthesis of prevalence. Figures were extracted from published reports, and any lost information was requested from investigators. The quality of the included literature was evaluated by using the Newcastle-Ottawa Scale (NOS). Prevalence was pooled using random-effects meta-analyses. The presence of association was declared using P-values and an odds ratio with a corresponding 95% CI.

RESULTS

The pooled prevalence of khat use among students was 16.7% (13.7-19.7%). In the subgroup analysis, the highest prevalence was observed in the Oromia region, at 21.1% (15.5%, 26.7%), and an almost equal prevalence of 14.8% (10.6, 18.9) and 14.3% (10.3, 18.3) was observed in Amhara and the Southern Nation, Nationalities, and People's Region of Ethiopia, respectively. Being male (OR: 2.43 (1.73, 3.13)), being a Muslim religion follower (OR: 2.22 (1.6, 2.8)), being an alcohol user (OR: 2.3 (1.5, 3.0)), khat use by a family member (OR: 1.8 (1.4, 2.2)), peer pressure (OR: 4.4 (3.1, 5.6)), and being a cigarette smoker (OR: 8.5 (5.3, 11.7)) were found to be risk factors for khat chewing.

CONCLUSIONS

Khat use is a common problem among students. Health promotion, awareness on effect of khat, set policy on khat and substance use on the male sex, Muslim religion, alcohol user, having a family-member khat user, peer pressure, and being a cigarette smoker as possible risk factors for khat use among students.

LIMITATIONS

Irrespective of time restriction, all studies conducted in Ethiopia are included and cross-sectional in nature. Protocol no. CRD-42017081886.

Prevalence of, Factors Associated with and Level of Dependence of Psychoactive Substance Use among Mekelle University Students, Ethiopia

Background: Psychoactive substance use is a major public health concern globally. Though youth attending higher education institutions are considered particularly vulnerable to psychoactive substances, there is a paucity of evidence in Ethiopia. We aimed to determine the prevalence of psychoactive substance use, factors associated with psychoactive substance use and level of dependence among Mekelle University undergraduate students in Ethiopia. Methods: An institution-based quantitative cross-sectional survey was used to randomly (using multistage sampling) invite 1220 undergraduate students in April and May 2017 to participate. Multinomial logistic regression was used to identify factors associated with psychoactive substance use. Level of dependence was determined using the WHO’s Alcohol, Smoking and Substance Involvement Screening Test classification. Results: Among the eligible students approached, 1214 participants completed the survey, which yields a 99.5% response rate. The lifetime prevalence of psychoactive substance use was 66.5% (95% Confidence Interval (CI) = 64% to 69%) while the current prevalence was 49% (95% CI = 46% to 52%). A history of, but not current, psychoactive substance use was reported by 18%, while 33.5% reported never having used psychoactive substances. The current prevalence of alcohol use was 35.5%, tobacco 7.8% and khat 5.7%. Of the current users, 17% (95% CI = 14% to 20%) were at a moderate to high risk of dependency. Being over 21 years of age (adjusted odds ratio (AOR) = 1.6, 95% CI = 1.37 to 2.25), male (AOR = 3.13; 95% CI = 2.26 to 4.34), living in urban areas (AOR = 2.39, 95% CI = 1.77 to 3.23), an Orthodox Christian (AOR = 7.55, 95% CI = 4.56 to 12.48), and being in their 3rd year (AOR = 2.3, 95% CI = 1.49 to 3.55), 4th year (AOR = 2.0, 95% CI = 1.2 to 3.51) and 5th year (AOR = 4.0, 95% CI = 2.81 to 7.67) at university were associated with currently using psychoactive substances. Being male and Orthodox Christian was associated with being an ex-smoker. Conclusions: Approximately half of Mekelle University undergraduate students were using psychoactive substances with almost one in five at risk of dependency. The likelihood of use increased with seniority. Evidence-based strategies are needed to prevent school-aged children from using psychoactive substances and university students becoming dependent on substances. Interventions designed to stop current psychoactive substance use may also have promise for reducing dependency.

Factors affecting current khat chewing among male adults 15-59 years in Ethiopia, 2016: a multi-level analysis from Ethiopian Demographic Health Survey

BACKGROUND

Regular khat chewing causes gingivitis, tooth loss, gastric disorders, cardiac complications, male impotence, sleeplessness, and several mental health problems. Based on the Ethiopian Demographic and Health Survey (EDHS) 2016, 12% of women and 27% of men have reported having ever chewed khat. Even though khat addiction is a major public health problem, studies that consider both individual level and community level factors are limited. Therefore, this study aimed to determine the prevalence and factors affecting current khat chewing among male adults in Ethiopia.

METHODS

Data from EDHS, a community-based cross-sectional study conducted from January 18, 2016, to June 27, 2016, was used. A multistage stratified cluster sampling technique was used to select participants. Both descriptive and analytical statistics were done. Bi-variable and multivariable multilevel logistic regression analyses were performed to determine factors affecting current khat chewing. Adjusted Odds ratio (AOR) with 95% Confidence Interval (CI) for variables with P-value < 0.05 was used as a measure of association.

RESULT

A total of 12,595 male adults were included. The prevalence of current khat chewing was 23.61% (95% CI: 22.87, 24.36). Age 20-24 years; (AOR = 2.68, 95% CI: 2.02, 3.56), being uneducated (AOR = 1.62, 95% CI: 1.10, 2.39), professional/technical/managerial job (AOR = 3.59, 95% CI: 2.18, 5.91), Muslim religion (AOR = 18.30, 95% CI: 13.54, 24.74), poorest wealth index (AOR = 0.67, 95% CI: 0.51, 0.89), being divorced (AOR = 0.38, 95% CI: 0.21, 0.69), history of alcohol drinking in the last 30 days (AOR = 2.15, 95% CI: 1.69, 2.73), and history of cigarette smoking in the last 30 days (AOR = 14.92, 95% CI: 10.88, 20.47), and Amhara region (AOR = 0.07, 95% CI: 0.04, 0.14) were significantly associated with khat chewing.

CONCLUSION

Khat chewing remains high in Ethiopia with certain regional variations. The uneducated, older age, Alcohol and cigarette users, Muslims, and professional workers were at higher risk of khat chewing whereas the poorest wealth index and being divorced reduced its risk. Policymakers should consider a multi-faceted policy approach that accounts for regional variation and the identified risk factors to alleviate the problem.

Predictors of substance use among Jimma University instructors, Southwest Ethiopia

BACKGROUND

Use of substances such as alcohol, khat leaves (Catha edulis) and tobacco has become one of the rising major public health and socioeconomic problems worldwide and dramatically increased in developing countries. The aim of this study was to assess the predictors of substance use among Jimma University instructors.

METHOD

Institutional based cross-sectional study design was conducted in 2018 among Jimma University instructors. A two-stage cluster sampling procedure was employed to select study participants by their departments and data was collected using structured, self-administered questionnaire with severity assessed by the standardized fifth version of a diagnostic statistical manual of mental health criteria for substance use disorder. Multivariate logistic regression was used to identify independent predictors of substance use. Variables with a P-value < 0.05 in the final fitting model were declared to be associated with the outcome variable.

RESULTS

A total of 330 instructors were involved in this study, with a response rate of 96.2%. About 225 of the respondents have ever used the substance in life (khat, alcohol, or cigarette or all) making the lifetime prevalence of substance use 68.2%. The lifetime prevalence of khat chewing, alcohol use, and smoking cigarette was 51.6, 81.3, and 17.3% respectively. The prevalence of substance uses disorder among users was 36.9%. Living with family (AOR = 0.220 [2.004-8.536] 95%CI), no family substance use history (AOR = 0.220 [0.098-0.495] 95% CI), friends substance use (AOR = 9.047 [4.645-17.620] 95% CI), Social norm favors substance use, (AOR = 1.123 [1.020-1.238] 95% CI), perceived benefit of substance use (AOR = 1.077 [1.008-1.151] 95% CI) were predictors of substance use.

CONCLUSION

Perception toward substance, the influence of family and peer were associated with substance use. Therefore, designing a multifaceted approach directed to an individual, interpersonal and community-level intervention targeted to substance misperception and social norms contributing to substance use.

Prevalence of Common Mental Disorder and Its Association with Khat Chewing among Ethiopian College Students: A Systematic Review and Meta-Analysis

Background

Mental disorder is a global burden that affects all groups of people. Young people, particularly college/university students, are more vulnerable to common mental disorders than the general population. Thus, students may use khat to gain immediate relief from their psychological distress which may worsen again after longer time of chewing. In Ethiopia, there are studies showing discrepant and inconsistent results of common mental disorder among college/university students. Therefore, this review sought to determine the prevalence of common mental disorder and its association with khat chewing among Ethiopian college/university students.

Methods

Different kinds of literature were searched from the databases of Google Scholar, PubMed/Medline, ScienceDirect, and PsycINFO. A total of 10 primary studies which report the prevalence of common mental disorder among Ethiopian college/university students were included in the review. The data were extracted using a standardized data extraction format prepared in Microsoft Excel. STATA version 14 statistical software was used for analysis. Cochran's Q test statistics and I ² test were used to assess heterogeneity. A random effects meta-analysis model was used to estimate the pooled prevalence of common mental disorder due to the variability of the studies. Lastly, the association between common mental disorder and khat chewing was conducted.

Results

The pooled prevalence of common mental disorder among Ethiopian college/university students was 37.73% (95% CI: 30.43, 45.03). The subgroup analysis showed the highest [51.9% (95% CI: 30.19, 73.70)] and lowest [33.28% (95% CI: 19.95, 46.60)] prevalences of common mental disorder among Ethiopian college/university students found in Amhara and South Nation Nationality and People regions, respectively. The pooled effect (odds ratio) of khat chewing on common mental disorder was 2.01 (95% CI: 1.38, 2.95).

Conclusions

In our review, it is found that more than one-third of college/university students suffered from common mental disorder. Khat chewers were found to be twofolds more vulnerable to develop common mental disorder than nonchewers.

Depression, Anxiety, Stress, and Associated Factors among Khat Chewers in Amhara Region, Northwest Ethiopia

Individuals with substance use disorder are prone to develop different psychiatric disorders. Substance abuse and associated problems are of current global concern that leads to mental health disorders which contributed about 14% of the global burden of the disease. It has become an epidemic in some parts of the African region with adolescents being the main victims of the ill health and social effects of substance use. This study is aimed at assessing the prevalence of depression, anxiety, and stress and associated factors among khat chewers in the Amhara region, 2019. A community-based cross-sectional study was done from February 14 to April 15, 2019. A purposive sampling technique was used to enroll the subjects. Data was collected using the face-to-face interview technique using the Depression Anxiety Stress Scale 21 (DASS-21) questionnaire. Descriptive statistics and bivariate and multivariate logistic regression were used to summarize the results. p value < 0.05 was considered statistically significant. A total of 478 participants were enrolled in the study with a response rate of 94.1%. The overall prevalence of depression, anxiety, and stress was 27.4%, 40.6%, and 18.8%, respectively. Around 43% of the respondents develop dependency from khat chewing. Working in a private sector, being self-employed, being jobless, spending 90 to 180 minutes and more, chewing 51-100 g and more, and chewing khat more than once per week were positively associated with stress. On the other hand, being a private sector worker, being jobless, completing secondary education, earning 1001-5000 ETB per month, chewing khat more than once per week, being khat dependent, and the presence of chronic illness were positively associated with anxiety. History of chronic illness and being khat dependent were positively associated with depression. The prevalence of depression, anxiety, and stress was high among khat chewers in the Amhara region. Special attention has to be given to khat chewers since khat chewing will double the burden of mental illness. Proper awareness and evaluation activities will reduce the impact of the problem.

Knowledge and Attitudes on Khat Use among Yemeni Health Sciences Students

Background: Khat chewing has a negative impact on an individual's life. Objectives: The study was execute to assess health sciences students' knowledge and attitudes regarding khat use in Yemen. Methods: This survey involved health sciences students from Aden University. Approximately 500 participants were selected through convenience sampling. The data were collected using a structured and validated self-administered questionnaire. The data were tabulated and descriptively analyzed. Results: The total number of respondents was 500. Almost half of the students reported that they chewed khat (n = 239, 48%). Approximately 66% (n = 330) of the students spent 2000 Yemeni riyals or less (USD1 = YER249.9) per day on khat. The main reasons for chewing khat were 'it is a social habit' (n = 155, 31%), followed by 'it improves my concentration when studying or working' (n = 140, 28%). Students knew that the effects of khat are similar to those of amphetamines (n = 210, 42.0%) and that khat is addictive (n = 254, 50.8%). Additionally, they knew that cathinone is the dependence-producing constituent of khat leaves (n = 269, 53.8%). The students agreed with the following statements: 'I will advise people to cease khat use'; 'Khat chewing is harmful to health'; 'Children and adolescents should not chew khat'; 'Khat chewing helps people stay awake'; and 'Health professionals serve as role models for patients and the public'. Conclusions: Khat chewing is prevalent among Yemeni university health sciences students. Only about half of the students recognized health risks associated with khat use. Also, among those who used khat, students endorsed positive benefits such as improved concentration.

Prevalence of lifetime substances use among students in Ethiopia: a systematic review and meta-analysis

BACKGROUND

The use of substances is a growing concern in Ethiopia, and their impacts on younger generation have been a concern of different professionals. Even though students are at high-risk of substance abuse, there is lack of comprehensive evidence for policy decision on substance use among students. Therefore, the aim of this systematic review and meta-analysis was to estimate the prevalence of common substances among students in Ethiopia.

METHOD

A comprehensive literature searches were done from biomedical databases: PubMed/Medline, African Journal Online, HINARI, Science Direct, and Google Scholar for article published until Dcember 31, 2017, and Addis Ababa Uiversity's electronic library search of unpublished thesis and dissertations. Two authors autonomously selected studies, extracted data, and evaluated quality of studies. The prevalence of lifetime substances use was estimated using the random effects model. Q and I2 statistics were computed to measure the extents of heterogeneity.

RESULTS

A total 676 study articles were identified from electronic databases, and 28 of them were included in meta-analysis. The analysis revealed that the lifetime prevalence of any substance use was 52.5% (95% CI 42.4-62.4%), khat 24.7% (95% CI 21.8-27.7%), alcohol 46.2% (95% CI 40.3-52.2%), and smoking cigarette 14.7% (95% CI 11.3-18.5%). Significant heterogeneity was observed but there was no significant publication bias. The lifetime prevalence of khat, alcohol, and cigarette smoking among high school vs university students was 22.5% (95% CI 15.2-30.7%) vs 25.1% (95% CI 21.9-28.5%), 41.4% (95% CI 22.1-62.1%) vs 47.8% (95% CI 39.9-55.7%), and 21.5% (95% CI 12.6-32.1%) vs 12.9% (95% CI 10.1-16.0%), respectively.

CONCLUSION

This meta-analysis highlighted the extent of lifetime prevalence of any substance, khat, alcohol, and cigarettes smoking among students in Ethiopia. Significant percent of high school students have exposed to substances. Policy makers should devise and implement strictly binding regulation to curb widespread of substances around educational institution premises at national level. Priority should be given to intervention strategies that help delay first use of substance to prevent problems later in life. Besides, the problem warrants regular national-level educational institutions based studies focusing on the magnitude, trajectory, and consequences of substance use among students. Systematic review registration: PROSPERO CRD42018082635.

Association between qat chewing and dyslipidaemia among young males

Objectives

This study investigated the association between qat chewing and prevalence and patterns of dyslipidaemia among young Yemeni males.

Methods

In this cross-sectional study, we used a multistage random cluster sampling method. Data were obtained using a questionnaire. Additionally, anthropometric measurements and fasting blood samples were collected. We used Program-Adult Treatment Panel III. The blood samples were analysed for lipid profile measurements including levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C).

Results

A total of 440 Yemeni male with mean age of 21.4 ± 3.6 years were enrolled. The students were divided into the following two groups—qat chewers (n = 283) and non-qat chewers (n = 77). The overall occurrence of dyslipidaemia was significantly higher in qat chewers than that in non-qat chewers (89.8% versus 80.5%) (P < 0.05). Hypercholesterolaemia, hypertriglyceridaemia, high LDL-C level, and mixed hyperlipidaemia were lower in qat chewers than in non-qat chewers (16.6%, 58.3%, 16.3%, and 10.6%, respectively, versus 20.8%, 64.9%, 18.2%, and 20.8%, respectively). Isolated hypertriglyceridaemia was slightly higher in qat chewers than in non-qat chewers (47.7% versus 44.2%). However, the incidence of low HDL-C level, isolated low HDL-C level, and isolated hypercholesterolaemia were generally higher in qat chewers than in non-qat chewers (83%, 25.1%, and 6%, respectively, versus 75.3%, 15.6%, and 0%, respectively).

Conclusion

This study showed high prevalence of dyslipidaemia among Yemeni male qat chewers. Low HDL-C level was the main lipid variable, followed by hypertriglyceridaemia. Genetic factors, war conditions, physical inactivity, and low-fat traditional Yemeni diet were considered the determinants of the study findings.

An assessment of khat consumption habit and its linkage to household economies and work culture: The case of Harar city

Background

This study investigates khat consumption habits and its linkage to the economy of a household and works culture in its ‘homeland,’ Harar. Khat consumption habit includes practices that are performed before, during, and after consuming khat. In Harar, it has permeated the local economy, social, political and spiritual lives. To evaluate how khat consumption habit is related to the economy of a household, this study compares the living standard and characteristics of khat consumers and non-consumers.

Methods

Both qualitative and quantitative approaches were used. Cluster sampling and lottery methods were used to identify respondents. Data were gathered through individual interviews and non-participant observation.

Results

The results of the study indicate that khat consumption habit affects the economy of the consumer household by negatively influencing their income usage and time management. Consumer households have significant, additional burdens on their income and time. The average monthly expenditure of a household on khat ceremonies is 1,800 ETB (30% of their income) and consumers spend an average of 112.5 hours monthly on khat related activities only. The habit of khat consumption also negatively associated with the work culture of consumers, as they leave for lunch break early and come back to work late.

Conclusion

Khat consumption habit does have a linkage to the bad economic situation of consumer households. It places a significant financial and time burdens on individuals, and as a result society. The work and saving culture of khat consumers are negatively affected. Khat consumption forces many into a cycle of borrowing and indebtedness. Concerned bodies should not underestimate the impacts of khat consumption on individuals and society.

Khat chewing prevalence and correlates among university staff in Ethiopia: a cross-sectional study

OBJECTIVES

Khat is an herbal cultivated plant growing mainly in Eastern Africa and Arabians. Chronic khat chewing leads to the development of liver toxicity, cardiovascular disease, sleeping disorder, psychosis, memory impairment, poor academic performance and variety of social and economic problems affecting the consumers and their families. Therefore, this study aimed to determine the prevalence of khat chewing and associated factors among Jimma university staff. An institution-based cross-sectional study was employed on 354 university staff. A self-administered questionnaire was used to collect the data. The analysis was done using Stata 14. A multivariable logistic regression model was used to identify associated factors of khat chewing among university staff. p ≤ 0.05 was employed to declare statistically significant factors.

RESULTS

The lifetime prevalence of khat chewing among university staff was 41.0% (95% CI 35.9-46.1%). The odds of khat chewing was higher among males (AOR = 2.66 95%, CI 1.52-4.68), participants who had khat chewer friends (AOR = 2.15 95% CI 1.18-3.93), alcohol users (AOR = 9.02, 95% CI 4.96-16.42) and participants who had khat chewer family member (AOR = 4.03, 95% CI 1.16-13.99). Since a significant proportion of staff chew khat, appropriate measures need to be taken to reduce its prevalence and adverse social and health consequences.

Factors affecting tobacco smoking in Ethiopia: evidence from the demographic and health surveys

Background

Tobacco smoking is growing at an alarming rate in the developing world and sub-Saharan Africa. Although Ethiopia has a relatively low rate in the region, it is not immune to the tobacco epidemic. The government of Ethiopia passed an anti-tobacco bill in 2015 that includes measures governing tobacco consumption, advertising, packaging, and labeling. To effectively address the challenge of tobacco control, the government should consider a number of aspects of tobacco production and consumption, such as local production in rural areas, as well as the complementarity nature of tobacco and khat use.

Methods

Using the World Bank’s Demographic and Health Surveys (2011 and 2016), this paper analyzes the key determinants of tobacco smoking in Ethiopia, emphasizing possible differences in various social contexts, across regions. More specifically, we assess the association between khat use and tobacco smoking while controlling for various observed individual-level, household-level, and community-level covariates. Using GPS data, we are able to capture the neighboring effects of smoking behavior in community clusters bordering other administrative regions as well as differences in smoking patterns between lowland and highland residents. We utilize a multilevel modeling framework and use a two-stage residual inclusion estimation method that accounts for the endogeneity of khat and tobacco use.

Results

The results suggest that chewing khat and geographic regions are statistically significant determinants of tobacco smoking even after controlling for various socioeconomic and demographic factors. Altitude information analysis suggests that people living in lowlands are more likely to smoke compared to those living in highland areas. Additional analysis including interactions between regions and khat use indicate wide inter-regional variations in tobacco smoking by khat users. We also extend our analysis by interacting khat use with religious adherence. Results indicate a wide variation in tobacco smoking by khat chewers across different religious groups.

Conclusions

To effectively control tobacco smoking of the diverse communities in Ethiopia, policymakers should consider a multi-pronged policy approach that combines various policy tools that account for regional variation, the local social contexts, as well as the complementary nature of smoking and khat chewing practices.
