Perinatal depressive disorder prevalence in Africa: A systematic review and Bayesian analysis.

OBJECTIVE: To curb the burden of perinatal depression (PND) in Africa, it is important to have an accurate estimate of its burden in the continent. Hence, we determined the prevalence of (major) depressive disorder in the perinatal period in Africa. METHODS: We searched PubMed, EMBASE, Africa Index Medicus, and Africa Journal Online, to identify studies reporting the prevalence of (major) depressive disorder in the perinatal period in Africa, between January 1st 2000 and February 17th 2020. PND prevalence was estimated using Bayesian modelling. RESULTS: We identified 154 studies (192 data points; 113,147 women). In pregnant women, the prevalence of depressive disorder was 22.8% (95%Credible interval [CrI]: 21.5-24.1) among women with no specific condition and 31.9% (95%CrI: 30.2-33.6) among those with HIV. In post-partum, the prevalence was 21.2% (95%CrI: 20.0-22.5), 30.0% (95%CrI: 28.2-31.8), and 44.6% (95%CrI: 35.9-53.8) among women with no specific condition, with HIV, and with poor pregnancy outcomes, respectively. CONCLUSIONS: This study depicted a high prevalence of PND in Africa. This prevalence varied across pre-defined clinical profiles. HIV-infected women or those with poor pregnancy outcomes having a higher prevalence of depression. This highlights the need for more attention and preventive interventions geared towards these sub-groups.

Awareness and Vaccine Coverage of Hepatitis B among Cameroonian Medical Students.

BACKGROUND: The endemic nature of the hepatitis B virus (HBV) in Sub-Saharan Africa is a significant public health problem that places health care providers (medical students inclusive) at increased risk of occupational exposure. However vaccination against HBV is not systematic among medical students in Cameroon. Thus, we sought to evaluate awareness and HBV vaccine coverage among medical students in Cameroon. METHODS: Using semistructured questionnaire and a cross-sectional approach, medical students from 3 State Universities in Cameroon were evaluated for their knowledge, attitudes, and vaccination status against the HBV. Data were collected over a 3-month period. HBV vaccine status was defined as complete (3 doses), partial (1 and 2 doses), and unvaccinated. Data were entered and analyzed using Epi-info 7. RESULTS: There were 714 respondents among whom 186 (26.05%) had been vaccinated at least once against HBV. Sixty-six (9.24%) were partially vaccinated and 120 (16.81%) completely vaccinated. No student had done postvaccination serologic testing to confirm full immunisation. Eighty-three percent (83.00%) of respondents had adequate knowledge on HBV infection and vaccine, while 90.00% had adequate knowledge on HBV transmission. Most medical students had a positive attitude towards the HBV vaccine. The most common negative attitudes were worries about the side effects and fears of being infected by the vaccine. CONCLUSION: Despite adequate knowledge on HBV infection and vaccination only about 1 in 6 medical students had completed the HBV vaccination series. This highlights the need for better health policies aimed at increasing access and coverage of the HBV in at-risk populations like medical students.

Prevalence and predictors of recreational drug use among medical and nursing students in Cameroon: a cross sectional analysis.

OBJECTIVE: Medical and nursing students in Cameroon are likely to have mental health problems given the stressful nature of their studies. Paucity of mental health institutions in the country implies they hardly get access to professional help when needed and are obliged to develop coping strategies such as recreational drug use. This study aims to determine the prevalence and predictors of recreational drug use among a group of Cameroonian medical and nursing students. RESULTS: Cross-sectional analysis of 852 medical and nursing students (mean age 21.78 ± 3.14, 31.49% males) recruited by convenience sampling from three state-owned medical schools; and from two state-owned and two private nursing schools in Cameroon over a four-month period (January-April 2018). Information was collected via a printed self-administered and structured questionnaire from consenting students. Multivariable logistic regression analysis was used to identify independent predictors of recreational drug use. The overall prevalence of recreational drug use was 1.64% with tramadol and marijuana noted as the drugs used by these students. Independent predictors of recreational drug use were: presence of a chronic illness (OR 5.26; 95% CI 1.32, 20.97; p = 0.019), alcohol consumption (OR 5.08; 95% CI 1.54, 16.73; p = 0.008) and Total Oldenburg Burnout Inventory score (OR 1.11; 95% CI 1.02, 1.21; p = 0.021). The use of recreational drugs by medical and nursing students in Cameroon remains worrisome despite its very low prevalence, as it may negatively impact their performance and health.
