Barriers to Smoking Cessation Among Drug-Resistant Tuberculosis Patients in South Africa
Background: Drug-resistant tuberculosis (DR-TB) remains a significant cause of morbidity and mortality. The long-term health effects of smoking and the risk of adverse TB outcomes, including increased periods of infectiousness, have been reported among DR-TB patients in South Africa. Objectives: This study aimed to identify the barriers to smoking cessation among DR-TB inpatients at a hospital in Durban, South Africa. Methods: A qualitative design using in-depth interviews with a purposive sample of 20 DR-TB inpatients was employed. The sample included 15 men and 5 women aged 18-70 years who self-identified as smokers. Open-ended questions were used to explore barriers militating against smoking cessation among this sample. Data were analyzed with the aid of the software QSR NVivo10. Findings: Personal and structural-level barriers (factors) to smoking cessation were identified. Personal factors included addiction and non–addiction-related barriers. Addiction-related barriers included smoking history, cravings for a cigarette, smoking as part of a daily routine, and failed quit attempts. Non–addiction-related barriers included lack of knowledge about quit strategies, psychosocial stress, lack of the willpower to quit smoking, and the influence of peers. Structural barriers included ineffective health education programs, lack of extramural activities when on admission in hospital leading to a lot of spare time, lack of smoking cessation interventions, and access to cigarettes within and around the hospital environment. Patients expressed interest in smoking cessation and conveyed their frustration at the lack of appropriate support to do so. ConclusionsThe findings reiterate the need for smoking cessation intervention to be incorporated as an integral component of DR-TB management in South Africa. Many patients expressed an interest in pharmacological aids and psychological support to help them to quit smoking. Additionally, offering extramural activities and enforcing smoke-free policies in hospital facilities will help to reduce patients' access to cigarettes while at the hospital
E-cigarette advertising exposure among South African adults in 2017 : findings from a nationally representative cross-sectional survey
OBJECTIVES : In South Africa, the Control of Tobacco and Electronic Delivery Systems Bill seeks to regulate e-cigarettes as tobacco products, including their advertising, promotion and sponsorship. Population data on e-cigarette advertising in South Africa are needed to inform public health programs, practice and policy. We examined self-reported e-cigarette advertising exposure during 2017. DESIGN Cross-sectional. SETTING : Household-based survey. PARTICIPANTS : 3063 individuals who participated in the 2017 South African Social Attitudes survey, a nationally representative, in-person survey of the non-institutionalised civilian adult population aged ≥16 years EXPOSURE ‘In the past 12 months, have you seen advertisements or promotions for e-cigarettes (including e-shisha, e-pipe) on any of the following media: newspapers/ magazines, billboards, in the malls or any other source?’ MAIN OUTCOMES : Beliefs and attitudes regarding e-cigarettes. FINDINGS : Participants’ mean age was 37.7 years. Overall, 20.1% reported exposure to e-cigarette advertisements. By age, exposure was most prevalent among those aged 16–19 years (24.6%). Top sources of exposure among those exposed were stores, 40.7%; malls, 30.9%; and television, 32.5%. Of those aware of e-cigarettes, 61.2% believed ‘e-cigarette advertisements and promotion may make adolescents think of smoking traditional cigarettes’; 62.7% believed that ‘e-cigarette advertisements and promotions may make ex-smokers think of starting smoking cigarettes again’; and 59.5% supported the statement that ‘e-cigarette smoking should be banned indoors just as traditional cigarette smoking’. Notably, teens aged 16–19 reported the lowest prevalence (49.0%) of those believing that ‘e-cigarette advertisements and promotion may make adolescents think of smoking traditional cigarettes’, whereas this percentage was highest among those aged 55–64 years (73.2%). CONCLUSION : Comprehensive regulatory efforts are needed to address e-cigarette advertising, marketing and sponsorship in order to protect public health. The urgent enactment of the new tobacco control legislation, The Control of Tobacco Products and Electronic Delivery Systems Bill, can help reduce youth exposure to e-cigarette advertising in South Africa.http://bmjopen.bmj.comam2022School of Health Systems and Public Health (SHSPH
Tobacco use and nicotine dependence among people living with HIV who drink heavily in South Africa: a cross-sectional baseline study
Abstract
Systematic review of feasibility and acceptability of psychosocial interventions for schizophrenia in low and middle income countries
Abstract
Background
In low and middle income countries there is evidence to suggest effectiveness of community-based psychosocial interventions for schizophrenia. Many psychosocial interventions have however been conceptualized in high income countries and assessing their feasibility and acceptability in low and middle income countries is pertinent and the objective of this review.
Methods
Six databases were searched using search terms (i) “Schizophrenia”; (ii) “Low and middle income or developing countries” and (iii) “Psychosocial interventions”. Abstracts identified were extracted to an EndNote Database. Two authors independently reviewed abstracts according to defined inclusion and exclusion criteria. Full papers were accessed of studies meeting these criteria, or for which more information was needed to include or exclude them. Data were extracted from included studies using a predesigned data extraction form. Qualitative synthesis of qualitative and quantitative data was conducted.
Results
14 037 abstracts were identified through searches. 196 full articles were reviewed with 17 articles meeting the inclusion criteria. Little data emerged on feasibility. Barriers to feasibility were noted including low education levels of participants, unavailability of caregivers, and logistical issues such as difficulty in follow up of participants. Evidence of acceptability was noted in high participation rates and levels of satisfaction with interventions.
Conclusions
While there is preliminary evidence to suggest acceptability of community-based psychosocial interventions for schizophrenia in low and middle income countries, evidence for overall feasibility is currently lacking. Well-designed intervention studies incorporating specific measures of acceptability and feasibility are needed
Promotion, prevention and protection: interventions at the population- and community-levels for mental, neurological and substance use disorders in low- and middle-income countries
Background In addition to services within the health system, interventions at the population and community levels are also important for the promotion of mental health, primary prevention of mental, neurological and substance use (MNS) disorders, identification and case detection of MNS disorders; and to a lesser degree treatment, care and rehabilitation. This study aims to identify “best practice” and “good practice” interventions that can feasibly be delivered at these population- and community-levels in low- and middle-income countries (LMICs), to aid the identification of resource efficiencies and allocation in LMICs. Methods A narrative review was conducted given the wide range of relevant interventions. Expert consensus was used to identify “best practice” at the population-level on the basis of existing quasi-experimental natural experiments and cost effectiveness, with small scale emerging and promising evidence comprising “good practice”. At the community-level, using expert consensus, the ACE (Assessing Cost-Effectiveness in Prevention Project) grading system was used to differentiate “best practice” interventions with sufficient evidence from “good practice” interventions with limited but promising evidence. ResultsAt the population-level, laws and regulations to control alcohol demand and restrict access to lethal means of suicide were considered “best practice”. Child protection laws, improved control of neurocysticercosis and mass awareness campaigns were identified as “good practice”. At the community level, socio-emotional learning programmes in schools and parenting programmes during infancy were identified as “best practice”. The following were all identified as “good practice”: Integrating mental health promotion strategies into workplace occupational health and safety policies; mental health information and awareness programmes as well as detection of MNS disorders in schools; early child enrichment/preschool educational programs and parenting programs for children aged 2–14 years; gender equity and/or economic empowerment programs for vulnerable groups; training of gatekeepers to identify people with MNS disorders in the community; and training non-specialist community members at a neighbourhood level to assist with community-based support and rehabilitation of people with mental disorders. Conclusion Interventions provided at the population- and community-levels have an important role to play in promoting mental health, preventing the onset, and protecting those with MNS disorders. The importance of inter-sectoral enga

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
