Background and aims: Population‐level alcohol use data are available from high‐income countries, but limited research has been conducted in sub‐Saharan Africa. This systematic review and meta‐analysis aimed to summarize population‐level alcohol use in sub‐Saharan Africa.Method: Databases searched included PubMed, EMBASE, PsycINFO and AJOL, without language restrictions. Searches were also conducted in the Global Health Data Exchange (GHDx) and Google Scholar. Search terms encompassed ‘substance’ or ‘substance‐related disorders’ and ‘prevalence’ and ‘sub‐Saharan Africa’. We included general population studies on alcohol use (including any use, high‐risk alcohol use and alcohol use disorders) from 2018 onwards. Prevalence data for alcohol use among sub‐Saharan African adolescents (10–17) and adults (18+) were extracted. Analyses included life‐time and past 12‐ and 6‐month alcohol use.Results: We included 141 papers. Among adolescents, the life‐time prevalence of alcohol use was 23.3% [95% confidence interval (CI) = 11.3–37.1%], 36.2% (CI = 18.4–56.1%) in the past year and 11.3% (CI = 4.5–20.4%) in the past 6 months. Among adolescents, 12‐month prevalence of alcohol use disorder and alcohol dependence were 7.7% (CI = 0.0–27.8%) and 4.1% (CI = 1.4–7.9%), respectively. Among adults, the life‐time prevalence of alcohol use was 34.9% (CI = 17.7–54.1%), 27.1% (CI = 5.0–56.4%) in the past year and 32.2% (CI = 19.8–46.0%) in the past 6 months. Among adults, the 12‐month prevalence of alcohol use disorder and alcohol dependence were 9.5% (CI = 0.0–30.4%) and 4.3% (CI = 0.8–9.8%), respectively. The highest weighted life‐time prevalence of alcohol use, 86.4%, was reported in Tanzania among adults. The highest weighted past 6‐month prevalence of alcohol use, 80.6%, was found in Zambia among adolescents.Conclusion: Alcohol use patterns vary across countries and subregions within sub‐Saharan Africa, and comprehensive population‐level data on alcohol use remain scarce in numerous sub‐Saharan African countries. The prevalence of alcohol use disorder is common among adolescents in sub‐Saharan Africa.

Objective. Attention deficit hyperactivity disorder (ADHD) is one of the most common behavioral disorders in childhood with long-term outcomes. Although ADHD is the most studied behavioral disorders of childhood in developed countries, few studies have been conducted in Ethiopia. The aim of this study was to determine the prevalence of ADHD in rural parts of Ethiopia. Method. A cross-sectional study was conducted from May to June 2015 among children aged 6 to 17 years living in rural areas. A multistage cluster sampling technique was used to select 1302 participants. The Disruptive Behavior Disorder Rating Scale was used to collect the data. Logistic regression analysis was used to see statistically significant variables. Result. The prevalence rate of attention deficit hyperactivity disorder (ADHD) among children was 7.3%. Being male (Adjusted Odds Ratio (AOR) = 1.81, 95% CI: (1.13, 2.91)); living with a single parent (AOR = 5.0, 95% CI: (2.35, 10.65)); child birth order/rank (AOR = 2.35, 95% CI: (1.30, 4.25)); and low family socioeconomic status (AOR = 2.43, 95% CI: (1.29, 4.59)) were significantly associated with ADHD. Conclusion. The ADHD prevalence rate was found to be similar with global reports. Prevention and early management of maternal complications is important to reduce the prevalence of ADHD among children.

Background and Aims: The most available data on the prevalence of cannabis use come from population surveys conducted in high‐income countries in North America, Oceania and Europe. Less is known about the prevalence of cannabis use in Africa. This systematic review aimed to summarize general population‐level cannabis use in sub‐Saharan Africa since 2010.Methods: A comprehensive search was conducted in PubMed, EMBASE, PsycINFO and AJOL databases in addition to Global Health Data Exchange and grey literature without language restriction. Search terms related to ‘substance’, ‘Substance‐Related Disorders’ and ‘Prevalence’ and ‘Africa South of the Sahara’ were used. Studies that reported cannabis use in the general population were selected, while studies from clinical populations and high‐risk groups were excluded. Prevalence data on cannabis use in the general population of adolescents (10–17 years) and adults (≥ 18 years) in sub‐Saharan Africa were extracted.Results: The study included 53 studies for the quantitative meta‐analysis and included 13 239 participants. Among adolescents, the life‐time, 12‐month and 6‐month prevalence of cannabis use were 7.9% [95% confidence interval (CI) = 5.4–10.9%], 5.2% (95% CI = 1.7–10.3%) and 4.5% (95% CI = 3.3–5.8%), respectively. The corresponding life‐time, 12‐month and 6‐month prevalence of cannabis use among adults were 12.6% (95% CI = 6.1–21.2%), 2.2% (95% CI = 1.7–2.7%, with data only available from Tanzania and Uganda) and 4.7% (95% CI = 3.3–6.4%), respectively. The male‐to‐female life‐time cannabis use relative risk was 1.90 (95% CI = 1.25–2.98) among adolescents and 1.67 (CI = 0.63–4.39) among adults.Conclusions: Life‐time cannabis use prevalence in sub‐Saharan Africa appears to be approximately 12% for adults and just under 8% for adolescents.

Aim: To assess the prevalence and associated factors of suicidal behaviour (suicidal ideation, plan or suicide attempt) in postpartum mothers. Method: An institutional cross-sectional study was employed from March to April 2017. Setting: Two primary health centres and one referral hospital in northwestern Ethiopia. Participants: A total of 1065 mothers aged ≥18 years during routine postnatal care were included and 988 of them completed the study. Those who were unable to communicate due to illness were not included. Outcome measure: Mothers who visit for routine postnatal care were assessed for suicidal behaviour using a suicidal screening tool. Logistic analysis was employed with adjusted OR (AOR) and 95% CI, and with p value less than 0.05 as the level of significance. Results: The prevalence of suicidal behaviour (suicidal ideation, plan or suicide attempt) was found at 14.0% (138/988) (95% CI 12.00 to 16.00) in postpartum mothers. Poor wealth of the mother (AOR=2.80, 95% CI 1.18 to 6.84), unplanned pregnancy of the current child (AOR=2.28, 95% CI 1.48 to 3.54), history of rape (AOR=2.26, 95% CI 1.42 to 3.61) and sickness of the new child (AOR=1.68, 95% CI 1.12 to 2.52) were significantly associated with suicidal behaviours. Conclusion: Suicidal behaviour was found pretty high among postpartum mothers and was associated with poor wealth, unplanned pregnancy, history of rape and sickness of the new infant. It is recommended to screen mothers for possible suicidal behaviour during routine postnatal care.

Even though United Nation announced that all persons with a mental illness shall be treated with humanity and respect for the inherent dignity of the human being, up to now, the use of coercion (physical restrain) is still considered as unavoidable in managing abnormal behavior of psychiatric patients. But, there is no information regarding the magnitude and contributing factors of physical restrain among bipolar patients in low-income countries like Ethiopia. A cross-sectional study was conducted at Amanuel Mental Specialized Hospital from May 1 to June 1, 2015 among 400 participants who were selected by systematic random sampling technique. Data were collected by interviewing; adjusted odd ratios (AOR) with 95% confidence intervals (CI) were used and p value <0.05 was considered as statistically significant. The prevalence of physical restrain was 65%. Factors like, having two or more episodes [AOR = 1.84 95% CI (1.16, 2.93)], history of aggression [AOR = 2.14, 95% CI (1.26, 3.63)], comorbid illness [AOR = 1.76, 95% CI (1.26, 3.63)], use of antipsychotic [AOR = 1.79, 95% CI (1.08, 2.95)] and current use of Khat [AOR = 1.83, 95% CI (1.10, 3.04)] were associated significantly. The prevalence of physical restraint is found high among bipolar patients and it needs public health attention.

Objective. Postpartum period is a state of instability that may be accompanied by mood liability, anxiety, insomnia, and neuropsychiatric disturbance in women. This neuropsychiatric disturbance has a negative influence on the child’s psychological and physical development. Our aim was to see the level of sleep difficulties among postpartum mothers in three obstetric care settings in Ethiopia. Method. Institutional based cross-sectional study was conducted at one referral hospital and two health centers. A total of 988 postpartum mothers had been interviewed for sleep difficulties by using Athens Insomnia Scale (AIS). Adjusted Odd Ratio (AOR) and 95% Confidence Interval (CI) were used and P-value <0.05 was used for indicating significant variables. Result. The prevalence of sleep difficulty between four to six weeks of postpartum period was 21.8% (215/988). Marital status of divorced/widowed/separated [AOR= 2.29, 95% CI (1.40, 6.08)], no educational opportunity [AOR= 2.35, 95% CI (1.57, 3.51)], having poor social support [AOR=2.82, 95% CI (1.63, 4.88)], alcohol use [AOR=1.58, 95% CI (1.13, 2.22)], history of depression [AOR=1.93, 95% CI (1.13, 3.31)], and who has poor support from husband [AOR=1.94, 95% CI (1.18, 3.18)] had association with sleep difficulty. Conclusion. There is a high magnitude of sleep difficulties during four to six weeks of postpartum period in postpartum mothers and they are associated with many preventable risk factors.
