RESUMO Objetivo: Avaliar a sazonalidade da bronquiolite aguda no Brasil durante a temporada 2020–2022 e compará-la com a das temporadas anteriores. Métodos: Os dados de incidência de internações por bronquiolite aguda em lactentes <1 ano de idade foram obtidos do Departamento de Informática da base de dados da Saúde Pública Brasileira para o período entre 2016 e 2022. Esses dados também foram analisados por macrorregiões do Brasil (Norte, Nordeste, Sudeste, Sul e Centro-Oeste). Para descrever características sazonais e de tendência ao longo do tempo, utilizamos o Modelo de Médias Móveis Integradas Autorregressivas Sazonais. Resultados: Em comparação com o período pré-COVID-19, a incidência de hospitalizações relacionadas com bronquiolite aguda diminuiu 97% durante as intervenções não farmacológicas (março de 2020 – agosto de 2021), mas aumentou 95% após a flexibilização das intervenções não farmacológicas (setembro de 2021 – dezembro de 2022), resultando no aumento geral de 16%. Durante o período pré-COVID-19, as hospitalizações por bronquiolite aguda seguiram um padrão sazonal, que foi interrompido em 2020–2021, mas recuperaram-se em 2022, com um pico ocorrido em maio, aproximadamente 4% superior ao pico pré-COVID-19. Conclusões: Este estudo ressalta a influência significativa das intervenções contra a COVID-19 nas hospitalizações por bronquiolite aguda no Brasil. A restauração de um padrão sazonal em 2022 sublinha a interação entre as medidas de saúde pública e a dinâmica das doenças respiratórias em crianças pequenas.

ABSTRACT Objective: To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020–2022 season and compare it with the previous seasons. Methods: Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. Results: Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 – August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 – December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020–2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. Conclusions: This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

El descubrimiento de conocimiento en bases de datos de KDD - Educacional, el análisis de técnicas de minería de datos de clasificación y agrupación, y el complemento de análisis de datos con la inteligencia de negocios determinaron los factores desde la perspectiva de la institución, del docente y de los estudiantes que inciden en el proceso de educación en línea, donde se demuestra además, la importancia del modelo de educación, la metodología del proceso de enseñanza aprendizaje, el entorno de aprendizaje y el bienestar de los docentes y estudiantes que garantizan una educación superior en línea de calidad con igualdad de oportunidades en el acceso.

Abstract: The COVID-19 pandemic significantly impacted higher education, forcing a rapid transition from face-to-face modality to the emerging online learning modality. This transition exposed several challenges, including, inequitable access to technology, global health and economic crisis, and specific difficulties faced by both teachers and students in Ecuador. Knowledge discovery in KDD - Educational databases, the analysis of classification and clustering data mining techniques and the complement of data analysis with business intelligence determined the factors from the perspective of the institution, teachers and students that influence the online education process. In addition, the importance of the education model, the teaching-learning process methodology, the learning environment, and the well-being of teachers and students that guarantee quality online higher education with equal access opportunities is demonstrated.

Abstract The present study aims to identify the impact generated by the information media, social networks and the media on Peruvian university students in the context of the COVID19 quarantine in Peru, and to know how it relates to the emotional state, and to the compliance with health recommendations. This retrospective correlational study collected information from 396 students from a Peruvian university, Universidad Nacional Mayor de San Marcos, through a virtual survey conducted during two weeks of the Peruvian quarantine (March 13 - May 13, 2021). The main results show that there is an association between the effects of the media and compliance with health recommendations. The most reassuring messages came from authorities such as the president of Peru, the university, and government text messages; as well as television; while the most disturbing messages were spread through social networks and other media. Furthermore, the findings show that university students mostly complied with the main recommendations of the Peruvian government and the WHO.

Resumen El presente estudio tiene como objetivo identificar el impacto que generan los medios de información, las redes sociales y los medios de comunicación en los estudiantes universitarios peruanos en el contexto de la cuarentena de COVID19 en Perú, y conocer cómo se relaciona con el estado emocional y el cumplimiento de las recomendaciones de salud. Este estudio correlacional retrospectivo recopiló información de 396 estudiantes de una universidad peruana, la Universidad Nacional Mayor de San Marcos, a través de una encuesta virtual realizada durante dos semanas de la cuarentena peruana (del 13 de marzo al 13 de mayo del 2021). Los principales resultados muestran que existe una asociación entre los efectos de los medios y el cumplimiento de las recomendaciones sanitarias. Los mensajes más tranquilizadores vinieron de autoridades como el presidente del Perú, la universidad y los mensajes de texto del gobierno; así como de la televisión; mientras que los mensajes más inquietantes se difundieron a través de las redes sociales y los otros medios de comunicación. Además, los hallazgos muestran que los estudiantes universitarios cumplieron mayormente con las recomendaciones principales del gobierno peruano y de la OMS.

Abstract As a result of COVID-19, new dynamics emerged in many urban systems, including the acquisition and distribution of food. The pandemic revealed vulnerabilities in the functioning of facilities and intensified problems such as informality, insecurity, and immigration. In order to contribute to the identification and characterization of these dynamics within food markets, a case study methodology was adopted for this article using mixed techniques - a quantitative approach using a survey and a qualitative approach featuring a focus group. Both methods were applied in the San Roque market in the Metropolitan District of Quito, an iconic food market and distribution facility. The results highlight new commercial dynamics and preferences, as in recent years informal trade and the presence of supermarket chains have proliferated; new logistic means have been created; and wholesale trade has intensified. In addition, the pandemic accentuated the vulnerability of the market at the administrative level and the precariousness of some informal jobs, in turn, accelerated changes among traders. It is concluded that these dynamics merit new conceptual, organizational, and spatial approaches in architectural and urban terms, as well as different policies that favor the sustainable management of markets.

Resumen A raíz de la covid-19 se dieron nuevas dinámicas en muchos sistemas urbanos entre las que destaca la de adquisición y distribución de alimentos. La pandemia mostró la vulnerabilidad en el funcionamiento de equipamientos e intensificó problemáticas como la informalidad, la inseguridad y la inmigración. Con el objetivo de aportar a la identificación y caracterización de estas dinámicas dentro de los mercados de alimentos, para el presente artículo se adoptó una metodología de caso de estudio con técnicas mixtas: cuantitativas por medio de una encuesta y cualitativas a partir de un grupo focal. Ambas técnicas se aplicaron en el mercado San Roque en el Distrito Metropolitano de Quito, equipamiento icónico en cuanto a la comercialización y distribución de alimentos. En los resultados sobresalen las nuevas dinámicas y preferencias comerciales, ya que en los últimos años han proliferado el comercio informal y la presencia de cadenas de supermercados, se han creado nuevos medios logísticos y se ha intensificado el comercio mayorista. Además, la pandemia acentuó la vulnerabilidad del mercado a nivel administrativo y la precarización de algunos trabajos informales, a su vez, aceleró un cambio entre el grupo de comerciantes. Se concluye que estas dinámicas ameritan nuevas aproximaciones conceptuales, organizativas y espaciales a escala arquitectónica y urbana, y también distintas políticas que favorezcan la gestión sostenible de los mercados.

RESUMEN Introducción: el SARS-CoV-2 desde el 2020 generó innumerables desafíos. El decúbito prono se utilizó para mejorar la oxigenación, y la terapia nutricional se adaptó para cubrir los requerimientos y reducir complicaciones. Objetivos: evaluar la tolerancia de la nutrición enteral y su adecuación energética en pacientes ventilados en decúbito prono con infección por SARS-CoV-2, en sala respiratoria del Departamento de Cuidados Intensivos Adultos del Hospital de Clínicas-Facultad de Ciencias Médicas - Universidad Nacional de Asunción, de marzo a julio 2021. Metodología: estudio observacional, descriptivo, retrospectivo, de corte transversal, de casos consecutivos, con información obtenida de fichas de pacientes de terapia intensiva, que recibieron soporte nutricional en posición prona. Se tomaron datos demográficos, clínicos y nutricionales. Se evaluó la tolerancia nutricional durante la posición prona, definiéndola como la presencia de un volumen de residuo gástrico < 500 mL cada 6 h.. La adecuación energética fue determinada teniendo en cuenta el porcentaje cumplido de la prescripción nutricional. Resultados: se reclutaron 41 pacientes. El 60,9 % eran hombres; la mediana de edad fue 55 años (RIC=23). Las principales comorbilidades fueron obesidad (57,3 %) e hipertensión arterial (43,9 %). El 85,4 % presentó buena tolerancia gástrica en posición prono, con residuo gástrico menor a 500 ml. El porcentaje de adecuación energética fue de 84 %. Conclusión: la terapia nutricional enteral en decúbito prono fue bien tolerada por la mayoría de nuestros pacientes, posibilitando alcanzar los requerimientos nutricionales indicados.

ABSTRACT Introduction: SARS-CoV-2 since 2020 has generated countless challenges. Prone position was used to improve oxygenation, and nutritional therapy was adapted to meet requirements and reduce complications. Objectives: evaluate the tolerance of enteral nutrition and its energetic adequacy in ventilated patients in the prone position with SARS-CoV-2 infection, in the respiratory room of the Adult Intensive Care Department of the Hospital de Clínicas - Facultad de Ciencias Médicas - Universidad Nacional de Asunción, from March to July 2021. Methodology: observational, descriptive, retrospective, cross-sectional study of consecutive cases, with information obtained from records of intensive care patients, who received nutritional support in a prone position. Demographic, clinical and nutritional data were taken. Nutritional tolerance was evaluated during the prone position, defining it as the presence of a volume of gastric residue < 500 mL every 6 h. Energy adequacy was determined taking into account the percentage fulfilled of the nutritional prescription. Results: 41 patients were recruited. 60.9 % were men; the median age was 55 years (IQR=23). The main comorbidities were obesity (57.3 %) and high blood pressure (43.9 %). 85.4 % had good gastric tolerance in the prone position, with gastric residue less than 500 ml. The percentage of energy adequacy was 84 %. Conclusion: enteral nutritional therapy in the prone position was well tolerated by the majority of our patients, making it possible to achieve the indicated nutritional requirements.

Effective pandemic decision-making depends on scientific expert evidence, transparency about public health policy decision-making, its rationales and the evidence on which it is based. The South African government laudably committed its COVID-19 response to be guided by science and evidence. Yet, the expert advice that it received was not always readily made available to the public. This submission analyses the time elapsed between the submission of COVID-19 Ministerial Advisory Committees memoranda to the Minister of Health, and the Department of Health's subsequent publication of these for the period August 2020 - January 2024. It also summarises the outcomes of the Health Justice Initiative's access to information legal action against the department on expert advice and government decision-making during the pandemic.

BACKGROUND. South Africa (SA) has committed to eliminating malaria by 2028. However, the initial target was set for 2023. Additionally, the ongoing COVID-19 pandemic and the emergence of drug and insecticide resistance have been identified as potential stumbling blocks in the achievement of this goal. The impact of COVID-19 on the prevalence and distribution of malaria in SA is unclear. OBJECTIVE. To describe the trends and distribution of malaria before and during the pandemic and its associated lockdown strategies in one of the country's malaria-endemic provinces, Mpumalanga Province. METHOD. A descriptive, retrospective and cross-sectional study was conducted using Mpumalanga provincial malaria case data extracted from the provincial District Health Information System 2. The impact of COVID-19 on the prevalence and distribution of malaria was assessed in Mpumalanga Province between 2017 and 2022 using descriptive trend analysis. Malaria cases before (2017 - 2019) and post-COVID-19 (2020 - 2022) were cross-tabulated using Stata version 17. We used χ² tests to test for significant differences, set at p<0.05. RESULTS. During the study period, 25 380 malaria cases were reported, with the majority men (61%) >26 years old, with reported international travel, primarily to Mozambique. Limpopo Province (93%) accounted for most of the locally imported cases. Headaches and fever were the most common symptoms before and post COVID-19, while asymptomatic malaria carriage was higher during and post COVID (p<0.05). Prior to the pandemic reporting of the preferred treatment for uncomplicated malaria, Coartem use was at 53%, declining to 21% thereafter. Although COVID-19-related restrictions on human movement greatly reduced the malaria burden in Mpumalanga Province, the high-risk group (young mobile men) remained unchanged over the study period. Of concern were the marked reduction in the reporting of Coartem doses administered and the increased prevalence of asymptomatic carriage since 2020. The importation of malaria poses one of the biggest challenges to malaria elimination in Mpumalanga Province. CONCLUSION. This study highlighted the impact of COVID-19 and its related lockdown restrictions on the delivery of malaria health services in Mpumalanga Province. If malaria elimination is to be achieved, all aspects of the malaria programme must be strengthened urgently. Additionally, the health system and cross-border collaborations must also be strengthened.

ABSTRACT The aim of this study was to determine the differences in perceptions of learning in virtual and in-person modalities experienced during and after the COVID-19 pandemic in a group of pre-service teachers at the National University of the Altiplano (Puno - Peru). The method used was the hypothetical-deductive approach, of a descriptive nature, with an intrinsic comparative design, and data collection was conducted cross-sectionally. The sample consisted of 116 students from the fifth to the tenth semester during the academic period of 2022-II. A validated instrument with an internal consistency of 0.978 on the Cronbach's alpha was employed. Data processing was carried out using descriptive statistics and Student's t-tests to determine significant differences. The results reveal the presence of significant differences in the perception of learning between virtual and in-person modalities, with an average score of 3.20 and 2.88, respectively, on a scale of 1 to 4. In conclusion, these findings imply that, at least during the academic period of 2022-II at this institution, students experienced more effective and satisfying learning in the in-person modality. This could be attributed to several factors, such as direct interaction with teachers and peers, access to physical resources on the university campus, and greater structure in in-person classes.

RESUMEN El objetivo fue determinar las diferencias sobre las percepciones del aprendizaje en la modalidad virtual y presencial experimentadas durante y después de la pandemia por COVID-19 en un grupo de profesores en formación de la Universidad Nacional del Altiplano (Puno - Perú). El método empleado fue el hipotético deductivo, de tipo descriptivo, de diseño comparativo intrínseco y su forma de obtención de datos fue la transversal. La muestra estuvo conformada por 116 estudiantes del quinto al décimo ciclo correspondientes al periodo académico de 2022-II. Se empleó un instrumento validado con una consistencia interna de 0.978 en el alfa de Cronbach. El procesamiento de datos se realizó mediante pruebas de estadística descriptiva y pruebas t de Student para determinar si existen diferencias significativas. Los resultados indican la presencia de diferencias significativas en la percepción del aprendizaje entre las modalidades virtual y presencial, con una puntuación media de 3.20 y 2.88, respectivamente, en una escala del 1 al 4. En conclusión, estos hallazgos sugieren que, al menos durante el periodo académico de 2022-II en esta institución, los estudiantes experimentaron un aprendizaje más efectivo y satisfactorio en la modalidad presencial. Esto podría deberse a una serie de factores, como la interacción directa con profesores y compañeros, la accesibilidad a recursos físicos en el campus universitario y una mayor estructura en las clases presenciales.

Resumen: La pandemia de COVID-19 demostró que las políticas públicas relacionadas con la propiedad intelectual y el derecho de la competencia no fueron adecuadas o suficientemente articuladas para permitir el acceso oportuno de la población a las vacunas de manera equitativa, debido a distorsiones en su fabricación, distribución y venta cuando éstas estuvieron disponibles durante la pandemia. Esta investigación tiene como objetivo analizar, desde una perspectiva jurídica, si los problemas observados se originan en una inadecuada aplicación de la legislación que regula la propiedad intelectual y su relación con otras políticas públicas vinculadas a la competencia, o, eventualmente, en el ejercicio abusivo de tales derechos, y que, como consecuencia, distorsionaría el proceso de competencia en los mercados nacionales y regionales.

Abstract: The COVID 19 pandemic demonstrated that public policies related to intellectual property and competition law were not adequate or sufficiently articulated to allow timely access to vaccines in an equitable manner, due to distortions in the manufacture, distribution, and sale of COVID-19 vaccines when they were available during the pandemic. This research aims to analyze, from a legal perspective, whether the observed problems originate in an inadequate application of intellectual property legislation and its relationship with other public policies related to competition, or, eventually, in the abusive exercise of such rights, which, as a consequence, would distort the process of competition in national and regional markets.

Resumo: A pandemia de COVID 19 demostrou que as políticas públicas relacionadas com a propriedade intelectual e o direito de competência não foram adequados ou suficientemente articulados para permitir o acesso oportuno da população às vacinas de maneira equitativa, devido a distorções na fabricação, distribuição e venda de vacinas COVID-19, quando estavam disponíveis durante a pandemia. Esta investigação tem como objetivo analizar, desde uma perspectiva jurídica, se os problemas observados se originam em uma inadequada aplicação da legislação que regula a propriedade intelectual e sua relação com outras políticas públicas vinculadas à competência ou, eventualmente, no exercício abusivo de tais direitos, e que, como consequência, distorceria o processo de competência nos mercados nacionais e regionais.

Abstract: The Research Ethics Committee (CEP) has become an essential mechanism for social control in Brazilian research involving human subjects, contributing to the development of studies guided by ethical standards and to the protection of research participants. This article analyzes the performance of CEP in Western Amazonian institution, its history, operating conditions, trends, and different aspects between 2018 to 2022. The theoretical framework addresses the history of research involving human subjects, the origins and evolution of bioethics in the international context, bioethics in Brazil, and regulations on the ethical analysis of research. The data were collected through the Brazil Platform and reports from the institution's CEP. The CEP evaluated 865 research protocols, most of which were from Health Sciences. Additionally, it was observed that during 2018 to 2022 the covid-19 pandemic had a negative impact on the number of projects submitted for evaluation to the CEP. The 57% drop in the number of projects registered during 2020/2022 reveals the negative impact of this event on the execution of projects with human participants.

ABSTRACT The COVID-19 pandemic has reduced access to food and increased food insecurity. The objectives were to analyse the prevalence of Food and Nutritional Insecurity (FNI) in Brazilian adolescents during the COVID-19 pandemic according to sociodemographic characteristics and to examine the association between FNI and risk and protective behaviours in Brazilian adolescents during the that period. Cross-sectional study with data from the ‘ConVid teenagers – Behaviour Survey,’ carried out between June and October 2020, using a self-administered questionnaire via mobile phone or computer. The population was made up of teenagers aged 12 to 17, totalling 9,470. The Prevalence Ratio (PR) and 95% Confidence Interval (95% CI) were used, using Poisson regression with robust variance. The prevalence of FNI (26.1%) was higher among adolescents of black and mixed race/colour and who study in public schools. Adolescents who reported FNI had lower consumption of vegetables and fruits, less physical activity, and greater use of cigarettes and alcohol. FNI was more prevalent in adolescents with worse socioeconomic conditions, and adolescents with FNI showed a higher frequency of health risk behaviours, highlighting the importance of intersectoral public policies to reduce inequalities.

RESUMO A pandemia de covid-19 reduziu o acesso aos alimentos e aumentou a insegurança alimentar. Objetivouse analisar a prevalência de Insegurança Alimentar e Nutricional (IAN) em adolescentes brasileiros durante a pandemia de covid-19 segundo características sociodemográficas e examinar a associação entre IAN e comportamentos de risco e proteção em adolescentes brasileiros durante esse período. Estudo transversal com dados da ‘ConVid Adolescentes – Pesquisa de Comportamentos’, realizada entre junho e outubro de 2020, utilizando-se um questionário autoaplicado por meio de celular ou computador. A população foi adolescentes de 12 a 17 anos, totalizando 9.470. Utilizou-se a Razão de Prevalência (RP) e Intervalo de Confiança de 95% (IC95%), por meio da regressão de Poisson com variância robusta.

ABSTRACT The COVID-19 pandemic has reduced access to food and increased food insecurity. The objectives were to analyse the prevalence of Food and Nutritional Insecurity (FNI) in Brazilian adolescents during the COVID-19 pandemic according to sociodemographic characteristics and to examine the association between FNI and risk and protective behaviours in Brazilian adolescents during the that period. Cross-sectional study with data from the ‘ConVid teenagers – Behaviour Survey,’ carried out between June and October 2020, using a self-administered questionnaire via mobile phone or computer. The population was made up of teenagers aged 12 to 17, totalling 9,470. The Prevalence Ratio (PR) and 95% Confidence Interval (95% CI) were used, using Poisson regression with robust variance. The prevalence of FNI (26.1%) was higher among adolescents of black and mixed race/colour and who study in public schools. Adolescents who reported FNI had lower consumption of vegetables and fruits, less physical activity, and greater use of cigarettes and alcohol. FNI was more prevalent in adolescents with worse socioeconomic conditions, and adolescents with FNI showed a higher frequency of health risk behaviours, highlighting the importance of intersectoral public policies to reduce inequalities.

RESUMO A pandemia de covid-19 reduziu o acesso aos alimentos e aumentou a insegurança alimentar. Objetivouse analisar a prevalência de Insegurança Alimentar e Nutricional (IAN) em adolescentes brasileiros durante a pandemia de covid-19 segundo características sociodemográficas e examinar a associação entre IAN e comportamentos de risco e proteção em adolescentes brasileiros durante esse período. Estudo transversal com dados da ‘ConVid Adolescentes – Pesquisa de Comportamentos’, realizada entre junho e outubro de 2020, utilizando-se um questionário autoaplicado por meio de celular ou computador. A população foi adolescentes de 12 a 17 anos, totalizando 9.470. Utilizou-se a Razão de Prevalência (RP) e Intervalo de Confiança de 95% (IC95%), por meio da regressão de Poisson com variância robusta. A prevalência de IAN (26,1%) foi mais elevada entre os adolescentes da raça/cor preta e parda e que estudam em escola pública. Os adolescentes que relataram IAN tiveram menor consumo de hortaliças e frutas, menor prática de atividade física e maior uso de cigarros e álcool. A IAN foi mais prevalente em adolescentes com piores condições socioeconômicas, e, adolescentes com IAN apresentaram maior frequência de comportamentos de risco para a saúde evidenciando a importância de políticas públicas intersetoriais para a redução de desigualdades.

BACKGROUND. Trends data up to 2018 suggest that tobacco smoking was increasing in South Africa (SA), but only limited information is available on the impact of the COVID-19 pandemic on the current pattern of use of tobacco and nicotine products (TNPs). OBJECTIVES. To assess trends in sociodemographic patterns in the use of TNPs and the extent to which sociodemographic factors and non-cigarette tobacco use may explain possible changes in rates of TNP use between 2017/18 and 2021. METHODS. Data from three waves (2017, 2018 and 2021) of the South African Social Attitudes Survey (total N=8 140) were analysed. The sociodemographic correlates of current daily and non-daily use of factory-manufactured cigarettes (FMCs), roll-your-own (RYO) cigarettes, waterpipe/hubbly, electronic cigarettes (ECigs), snuff (a smokeless tobacco) and any combination of FMCs, RYO cigarettes and waterpipe/hubbly ('current smoking') in 2017/18 (pre-pandemic) were compared with those for 2021 (during the pandemic). Chi-square analyses and generalised linear models were used to compare the prevalence of TNP use between the two periods. A Blinda-Oaxaca decomposition analysis was also used to explore the roles of various sociodemographic factors, including any differences in the use of TNPs, that may explain any observed differences in smoking rates between 2017/18 and 2021. RESULTS. Current smoking increased significantly from 22.4% (95% confidence interval (CI) 20.4 - 24.5) in 2017/18 to 27.6% (95% CI 24.3 - 31.1) in 2021 (p=0.009). Smoking of FMCs did not change significantly overall between these two periods (20.1% v. 22.1%; p=0.240), except for a significant increase among those who self-identified as black African and a decrease among those who self-identified as coloured and those currently employed. However, the use of waterpipe/hubbly, ECigs, RYO cigarettes and snuff increased significantly. Women, individuals aged <35 years and black Africans had the largest increase in waterpipe/hubbly and ECig use. A decomposition analysis showed that increased waterpipe/hubbly and RYO use explained 52% and 15%, respectively, of the increase in smoking rates, while lower employment during 2021 compared with 2017/18 explained 15% of the increase in smoking rates during 2021. CONCLUSION. The use of all TNPs continued to increase in SA, particularly among women and unemployed people. These findings have policy and practice implications for addressing socioeconomic disparities in tobacco-related diseases.
