We utilized Global Adult Tobacco Survey data to examine singlestick purchases and related demographic characteristics in 10 African countries (Botswana, Cameroon, Ethiopia, Kenya, Nigeria, Mauritania, Senegal, South Africa, Uganda and Tanzania). Results show the weighted percentages and prevalence ratios with predicted marginal means to evaluate significant differences between groups (P < 0.05). The prevalence of singlestick purchases among the 10 African countries ranged from 48.4% in South Africa to 92.0% in Tanzania. Across countries, the incidence of singlestick purchases was higher in urban areas than rural areas in Kenya; among those aged 15-24 years versus those aged 45 years and older in Botswana, Ethiopia, Mauritania, Nigeria and South Africa; and among those aged 25-44 years versus those aged 45 years and older in Botswana, South Africa and Tanzania. The incidence in Botswana was higher among adults with no formal or primary education than among those with secondary or higher education. In South Africa, the incidence was higher among adults in the middle or lower wealth index than among those in the high or highest wealth index. The findings suggest opportunities for strengthening efforts to prevent singlestick purchases through effective legislation and enforcement in line with Article 16 of the World Health Organization Framework Convention on Tobacco Control., (Published by Oxford University Press 2024.

Introduction: Secondhand tobacco smoke (SHS) exposure causes diseases and death in adults and children. Evidence indicates that most SHS exposures occur at home and in the workplace. Therefore, home is a major place where adults and children can be effectively protected from SHS. This study examined the magnitude of SHS exposure at home and associated factors in eight sub-Saharan African countries., Aims and Methods: We analyzed 2012-2018 Global Adult Tobacco Survey data for Botswana, Cameroon, Ethiopia, Kenya, Nigeria, Senegal, Tanzania, and Uganda. We computed prevalence estimates of self-reported monthly SHS exposure at home reported as anyone smoking inside their home daily, weekly, or monthly. We calculated SHS exposure at home prevalence and applied multivariable logistic regression models to identify related factors., Results: Overall median prevalence of SHS exposure at home was 13.8% in the eight countries; ranging from 6.6% (95% CI: 5.7%, 7.6%) in Nigeria to 21.6% (95% CI: 19.4%, 24.0%) in Senegal. In multivariable analysis across the countries, SHS exposure at home was associated with living with a smoker, ranging from an adjusted odds ratio (AOR) of 4.6 (95% CI: 3.6, 5.8) in Botswana to 27.6 (95% CI: 20.1, 37.8) in Nigeria. SHS exposure at home was significantly associated with lower education attainment (Kenya and Ethiopia), and lower wealth index (Uganda, Senegal, and Botswana)., Conclusions: SHS exposure in homes was associated with the presence of a smoker in the home and lower socioeconomic status., (Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco 2022.)

Introduction: Increases in electronic cigarette (e-cigarette) awareness and current use have been documented in high income countries but less is known about middle and low income countries., Methods: Nationally representative household survey data from the first four Global Adult Tobacco Surveys to assess e-cigarettes were analyzed, including Indonesia (2011), Malaysia (2011), Qatar (2013), and Greece (2013). Correlates of e-cigarette awareness and current use were calculated. Sample sizes for Greece and Qatar allowed for further analysis of e-cigarette users., Results: Awareness of e-cigarettes was 10.9% in Indonesia, 21.0% in Malaysia, 49.0% in Qatar, and 88.5% in Greece. In all four countries, awareness was higher among male, younger, more educated, and wealthier respondents. Current e-cigarette use among those aware of e-cigarettes was 3.9% in Malaysia, 2.5% in Indonesia, 2.2% in Greece and 1.8% in Qatar. Across these four countries, an estimated 818 500 people are currently using e-cigarettes. Among current e-cigarette users, 64.4% in Greece and 84.1% in Qatar also smoked cigarettes, and, 10.6% in Greece and 6.0% in Qatar were never-smokers., Conclusions: E-cigarette awareness and use was evident in all four countries. Ongoing surveillance and monitoring of awareness and use of e-cigarettes in these and other countries could help inform tobacco control policies and public health interventions. Future surveillance should monitor use of e-cigarettes among current smokers and uptake among never-smokers and relapsing former smokers., Competing Interests: Declaration of Interests None declared., (© The Author 2015.
