    Previous research suggests that threats to security influence tourists’ risk perceptions and travel decision-making. This qualitative study investigates British domestic tourists’ risk perception in the light of the rapidly growing global trend of terrorism. This study yields three insights: (1) the incidence of terrorism produces an emotional response of fear and anxiety; (2) willingness to travel despite perceived travel risk varies depending on factors such as reason for travel, visual presence of security services, and the one-off nature of the attack; (3) the media’s influence on travel risk perception is a function of how the media is perceived

    Background. In sub-Saharan Africa, substance use among adolescents has continued to be a major public health concern, albeit poorly documented across many settings. Objective. To estimate the prevalence of substance use among adolescents in sub-Saharan Africa. Methods. We searched Pubmed, EMBASE, AJOL and Google Scholar for population-based studies on adolescents (age 10 - 19 years) and reporting on the prevalence of substance use across sub-Saharan Africa. Search dates were from January 2000 to December 2016. A random effects meta-analysis was conducted with pooled prevalence rates (and 95% confidence interval (95% CI)) of estimated substance abuse among adolescents in sub-Saharan Africa. Results. Twenty-seven studies across sub-Saharan Africa including 143 201 adolescents (mean age 15.6 years) were selected. The overall prevalence of ‘any substance use’ in sub-Saharan Africa was 41.6%, with the highest rate in Central Africa at 55.5%. The use of caffeinecontaining products (including coffee or kola nut) was most predominant at 41.2% (95% CI 24.3 - 58.1) but limited to West Africa. These were followed by alcohol at 32.8% (95% CI 26.0 - 39.5), tobacco products 23.5% (95% CI 17.7 - 29.3), khat 22.0% (95% CI 12.5 - 31.5) and cannabis 15.9% (95% CI 12.2 - 19.1). Other abused substances included depressants at 11.3% (95% CI 6.5 - 16.1), amphetamines 9.4% (95% CI 6.0 - 12.9), heroin 4.0% (95% CI 3.5 - 4.5) and cocaine 3.9% (95% CI 1.4 - 6.5). Conclusion. Our study reflects a high use of psychoactive substances and drugs among adolescents in sub-Saharan Africa. It is important that interventions and rehabilitation programmes are comprehensive and targeted at adolescents and parents in these settings

    Health-care workers’ occupational exposures to body fluids in 21 countries in Africa: systematic review and meta-analysis

    Get PDF
    Objective:To estimate the lifetime and 12-month prevalence of occupational exposure to body fluids among health-care workers in Africa. Methods: Embase®, PubMed® and CINAHL databases were systematically searched for studies published from January 2000 to August 2017 that reported the prevalence of occupational exposure to blood or other body fluids among health-care workers in Africa. The continent-wide prevalence of exposure was estimated using random-effects meta-analysis. Findings: Of the 904 articles identified, 65 studies from 21 African countries were included. The estimated pooled lifetime and 12-month prevalence of occupational exposure to body fluids were 65.7% (95% confidence interval, CI: 59.7–71.6) and 48.0% (95% CI: 40.7–55.3), respectively. Exposure was largely due to percutaneous injury, which had an estimated 12-month prevalence of 36.0% (95% CI: 31.2–40.8). The pooled 12-month prevalence of occupational exposure among medical doctors (excluding surgeons), nurses (including midwives and nursing assistants) and laboratory staff (including laboratory technicians) was 46.6% (95% CI: 33.5–9.7), 44.6% (95% CI: 34.1–55.0) and 34.3% (95% CI: 21.8–46.7), respectively. The risk of exposure was higher among health-care workers with no training on infection prevention and those who worked more than 40 hours per week. Conclusion: The evidence available suggests that almost one half of health-care workers in Africa were occupationally exposed to body fluids annually. However, a lack of data from some countries was a major limitation. National governments and health-care institutions across Africa should prioritize efforts to minimize occupational exposure among health-care workers

    Hepatitis B vaccination coverage among health-care workers in Africa: a systematic review and meta-analysis

    Get PDF
    Objective: To estimate full hepatitis B vaccination coverage (uptake of ≥3 doses of vaccine) among health-care workers (HCWs) in Africa. Methods: We systematically searched the PubMed®, Embase®, CINAHL and Psych-Info databases for studies published from January 2010 to October 2017 that reported full hepatitis B vaccination coverage among HCWs in Africa. A random effects meta-analysis was conducted to determine pooled estimates of full vaccination coverage. Results: Of the 331 articles identified, 35 studies from 15 African countries met the inclusion criteria and were included in the review. The estimated full hepatitis B vaccination coverage was 24.7% (95% CI: 17.3 – 32.0). Regional coverage was highest in northern Africa (62.1%, 95% CI: 42.5 – 81.7) and lowest in central Africa (13.4%, 95% CI: 4.5 – 22.3). Doctors were more likely (OR: 2.6, 95% CI: 1.8 – 3.7) to be fully vaccinated than Nurses with estimated pooled estimates of 52.4% (95% CI: 31.1 – 73.8) and 26.3% (95% CI: 9.7 – 42.9), respectively. Also, HCWs with 10 or more years of experience were more likely to be vaccinated than those with less than 10 years of experience (OR: 2.2, 95% CI: 1.5 – 3.3). The common reasons identified for non-vaccination of HCWs were unavailability of vaccine 50.5% (95% CI: 26.5 – 74.4), busy work schedule 37.5% (95% CI: 12.6 – 62.4) and cost of vaccination 18.4% (95% CI: 7.1 – 29.7). Conclusion: The evidence available suggests that many HCWs in Africa are at risk of Hepatitis B infection as only a quarter of them were fully vaccinated against Hepatitis B virus. This study highlights the need for all African governments to establish and implement hepatitis B vaccination policies for HCWs

    Copyright \ua9 2023 Sun, Ren, Zhu, Cheng, Liu, Li, Xia, Yuan, Adeloye, Rudan, Canoy, Song, on behalf of the Global Health Epidemiology Research Group (GHERG). Background: Adverse childhood experiences (ACEs) are associated with higher depressive risks in adulthood. Whether respondents’ ACEs are associated with their own depressive symptoms in adulthood and whether this association extends to their spouses’ depressive symptoms remain unexplored. Methods: Data were from China Health and Retirement Longitudinal Study (CHARLS), the Health and Retirement Study (HRS), and the Survey of Health, Ageing and Retirement in Europe (SHARE). ACEs were categorized into overall, intra-familial, and extra-familial ACEs. Correlations of couples’ ACEs were calculated using Cramer’s V and partial Spearman’s correlation. Associations of respondents’ ACEs with spousal depressive symptoms were assessed using logistic regression, and mediation analyses were conducted to explore the mediating role of respondents’ depressive symptoms. Results: Significant associations between husbands’ ACEs and wives’ depressive symptoms, with odds ratios (ORs) and 95% confidence intervals (CIs) of 2.09 (1.36–3.22) for 4 or more ACEs in CHARLS, and 1.25 (1.06–1.48) and 1.38 (1.06–1.79) for 2 or more ACEs in HRS and SHARE. However, wives’ ACEs were associated with husbands’ depressive symptoms only in CHARLS and SHARE. Findings in intra-familial and extra-familial ACEs were consistent with our main results. Additionally, respondents’ depressive symptoms mediated more than 20% of the effect of respondents’ ACEs on spousal depressive symptoms. Conclusion: We found that ACEs were significantly correlated between couples. Respondents’ ACEs were associated with spousal depressive symptoms, with respondents’ depressive symptoms mediating the association. The bidirectional implications of ACEs on depressive symptoms should be considered within household and effective interventions are warranted

    Background The burden of dementia is poorly understood in Nigeria. We sought to gather available epidemiologic evidence on dementia in Nigeria to provide country-wide estimates of its prevalence and associated risks. Methods We searched MEDLINE, EMBASE, Global Health, Africa Journals Online (AJOL) and Google Scholar for epidemiologic studies on dementia in Nigeria from 1990 to 2018. We pooled crude estimates using random effects meta-analysis. A meta-regression epidemiologic model, using the United Nations demographics for Nigeria, was used to estimate the absolute number of people living with dementia in Nigeria in 1995 and 2015. Results Our searches returned 835 studies, of which nine were selected. These included 10,820 individuals with a median age of 74.4 years. Heterogeneity ( I2 =98.8%, P<0.001) was high across studies. Five studies were conducted in the South-west, and four studies were rated as high quality. The pooled crude prevalence of dementia in Nigeria was 4.9% (95% confidence interval (CI) 3.0-6.9) with prevalence significantly higher in women (6.7%, 3.6-9.9) compared to men (3.1%, 1.2-5.0). Age 80+ (odds ratio (OR) 1.6, 1.3-1.9), female sex (OR 2.2, 1.4-3.4) and BMI ≤18.5 (OR 3.5, 1.2-10.1) were significant risks for dementia in Nigeria. Using our epidemiologic model, we estimated that the number of dementia cases increased by over 400% over a 20-year period, increasing from 63,512 in 1995 to 318,011 in 2015 among persons aged ≥60 years. Conclusion Our findings suggest the prevalence and cases of dementia have increased in Nigeria over the last two decades. Population-wide response to dementia is lacking

    Funding: This research is part of the Data and Connectivity National Core Study, led by Health Data Research UK in partnership with the Office for National Statistics and funded by UK Research and Innovation (grant ref MC_PC_20058). SVK acknowledges funding from a NRS Senior Clinical Fellowship (SCAF/15/02), the Medical Research Council (MC_UU_00022/2) and the Scottish Government Chief Scientist Office (SPHSU17).Background The dynamics of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission and severity of disease among children and young people (CYP) across different settings are of considerable clinical, public health and societal interest. Severe COVID-19 cases, requiring hospitalisations, and deaths have been reported in some CYP suggesting a need to extend vaccinations to these age groups. As part of the ongoing Early Pandemic Evaluation and Enhanced Surveillance of COVID-19 (EAVE II) study, we aim to investigate the uptake, effectiveness and safety of COVID-19 vaccines in children and young people (CYP) aged 0 to 17 years in Scotland. Specifically, we will estimate: (i) uptake of vaccines against COVID-19, (ii) vaccine effectiveness (VE) against the outcomes of symptomatic SARS-CoV-2 infection, hospitalisation, intensive care unit (ICU) admissions, and death; (iii) VE for first/second dose timing among different age groups and risk groups; and (iv) the safety of vaccines. Methods and analysis We will conduct an open prospective cohort study classifying exposure as time-varying. We will compare outcomes amongst first dose vaccinated and second dose vaccinated CYP to those not yet vaccinated. A Test Negative Design (TND) case control study will be nested within this national cohort to investigate VE against symptomatic infection. The primary outcomes will be (i) uptake of vaccines against COVID-19, (ii) time to COVID-19 infection, hospitalisation, ICU admissions or death, and (iii) adverse events related to vaccines. Vaccination status (unvaccinated, one dose and two doses) will be defined as a time-varying exposure. Data from multiple sources will be linked using a unique identifier. We will conduct descriptive analyses to explore trends in vaccine uptake, and association between different exposure variables and vaccine uptake will be determined using multivariable logistic regression models. VE will be assessed from time-dependent Cox models or Poisson regression models, adjusted for relevant confounders, including age, sex, socioeconomic status, and comorbidities. We will employ self-controlled study designs to determine the risk of adverse events following COVID-19 vaccination. Ethics and dissemination Ethics approval was obtained from the National Research Ethics Committee, South East Scotland 02. We will present findings of this study at international conferences, in peer-reviewed journals and to policy-makers.Publisher PDFPeer reviewe

    Get PDF
    Background Healthcare workers (HCWs) are at risk of occupational exposure to blood-borne pathogens through contact with human blood and other body fluids. This study was conducted to estimate the global and regional 1-year prevalence of percutaneous injuries (PCIs) among HCWs. Methods We systematically searched EMBASE, PubMed, CINAHL and PsychInfo databases for studies published from January 2008 to January 2018 that reported the prevalence of PCIs among HCWs. A random-effects meta-analysis was conducted to estimate pooled prevalence of PCIs among HCWs. Results Of the 5205 articles identified, 148 studies from 43 countries met the inclusion criteria. The pooled global 1-year prevalence estimate of PCIs was 36.4% [95% confidence interval (CI): 32.9–40.0]. There were substantial regional variations in the 1-year prevalence of PCIs, ranging from 7.7% (95% CI: 3.1–12.4) in South America to 43.2% (95% CI: 38.3–48.0) in Asia. The estimates for Africa and Europe were comparable with values of 34.5% (95% CI: 29.9–39.1) and 31.8% (95% CI: 25.0–38.5), respectively. The highest 1-year prevalence by job category was among surgeons, at 72.6% (95% CI: 58.0–87.2). The estimates for medical doctors (excluding surgeons), nurses (including midwives) and laboratory staff (including laboratory technicians) were 44.5% (95% CI: 37.5–51.5), 40.9% (95% CI: 35.2–46.7) and 32.4% (95% CI: 20.9–49.3), respectively. PCIs commonly occurred among HCWs working in hospital (41.8%, 95% CI: 37.6–46.0) than non-hospital (7.5%, 95% CI: 5.9–9.1) settings. Conclusions Our findings suggest high rates of PCIs among HCWs with direct patient care across many regions of the world. However, paucity of data from some countries was a major limitation

    Global access to antibiotics without prescription in community pharmacies: a systematic review and meta-analysis

    Get PDF
    Objective: To estimate the proportion of over-the-counter antibiotic requests or consultations that resulted in non-prescription supply of antibiotics in community pharmacies globally. Methods: We systematically searched EMBASE, Medline and CINAHL databases for studies published from January 2000 to September 2017 reporting the frequency of non-prescription sale and supply of antibiotics in community pharmacies across the world. Additional articles were identified by checking reference lists and a Google Scholar search. A random effects meta-analysis was conducted to calculate pooled estimates of non-prescription supply of antibiotics. Results: Of the 3302 articles identified, 38 studies from 24 countries met the inclusion criteria and were included in the review. All the included countries with the exception of one, classified antibiotics as prescription-only medicines. The overall pooled proportion of non-prescription supply of antibiotics was 62% (95% CI 53 – 72). The pooled proportion of non-prescription supply of antibiotics following a patient request was 78% (95% CI 59 - 97) and based on community pharmacy staff recommendation was 58% (95% CI 48 – 68). The regional supply of non-prescription antibiotics was highest in South America, 78% (95% CI 72 - 84). Antibiotics were commonly supplied without a prescription to patients with symptoms of urinary tract infections (68%, 95% CI 42 – 93) and upper respiratory tract infections (67%, 95% CI 55 - 79). Fluoroquinolones and Penicillins respectively were the most commonly supplied antibiotic classes for these indications. Conclusion: Antibiotics are frequently supplied without prescription in many countries. This overuse of antibiotics could facilitate the development and spread of antibiotic resistance
