High burden of abnormal cervical smears in South African primary health care
Cervical cancer is the second most common malignancy among South African women and the load of abnormal cervical smears has clinical, programmatic and policy implications. This cross-sectional study of women who presented for cervical cancer screening aimed to determine the prevalence of abnormal cervical smears and associated factors in primary health care (PHC) facilities in Gauteng—the most densely populated province in South Africa. A questio…
Trends in the prevalence and factors associated with indoor smoking in 24 countries Party to the WHO FCTC
INTRODUCTION: The health consequences of secondhand smoke (SHS) are a long-standing concern. The WHO Framework Convention on Tobacco Control (FCTC) is an evidence-based treaty that aims to protect people from health and environmental harms of commercial tobacco use and exposure to SHS. This study quantified the prevalence of daily smoking inside the house (indoor smoking) and change over time and examined the determinants of indoor smoking in 24 …

Acting on the Commercial Determinants of Health
‘Our world won’t be here if you continue to devastate the lands. There will be no more money to make.’ 19-year-old Australian (Arnot et al., 2023b) In 1986, when Health Promotion International was launched, the founding Chair of the Editorial Board, Professor Ilona Kickbusch, stressed that promoting health is not easy in the face of the well planned strategies of ‘powerful interest groups’ and the ‘wheelings and dealings of power politics’ [(Kick…

Tobacco Vendors’ Perceptions and Compliance with Tobacco Control Laws in Nigeria
Tobacco vendors are critical stakeholders in the tobacco supply chain. This study examined their perception, compliance, and potential economic impact of Nigeria's tobacco control laws related to the retail setting. This was a qualitative study involving in-depth interviews of 24 purposively selected tobacco vendors. The face-to-face interviews were aided by a semi-structured interview guide, audio-recorded, transcribed verbatim, and analyzed usi…
Cervical cancer screening in a population of black South African women with high HIV prevalence
Cervical cancer is largely preventable through early detection, but screening uptake remains low among black women in South Africa. The purpose of this study was to determine the prevalence and factors associated with cervical cancer screening in the past 10 years among black African women in primary health care (PHC) clinics, in Gauteng Province, South Africa. This was a cross-sectional study involving 672 consecutively recruited black women at …
Landscape of tobacco control in sub-Saharan Africa
Yearly, tobacco use kills about 8 million people globally, 80% of whom live in low/middle-income countries. Given sub-Saharan Africa's (SSA) rapidly increasing and youthful population, growing incomes and the increased presence of the tobacco industry, the number of tobacco users is growing. The region is predicted to face a heavier burden of tobacco-related diseases and deaths in the future. We examined the policy, advocacy, economic and media l…
Associations between electronic cigarette use and quitting behaviours among South African adult smokers
e-Cigarette use depressed long-term cessation. These findings can inform restrictions on unsubstantiated claims of e-cigarettes as cessation aids within South Africa
Geospatial spread of e-cigarette vape shops in South Africa and the relationship with tobacco product use among adults
Non-Smoker’s Exposure to Second-Hand Smoke in South Africa during 2017
Current South African tobacco control law allows for 25% designated smoking areas in some indoor public places. This study investigates non-smokers' exposure to second-hand smoke (SHS) in workplaces, homes, cafés/restaurants, and shebeens (local bars) using data from the 2017 South African Social Attitude Survey. Factors associated with any level of exposure were explored using multiple-variable-adjusted logistic regression analysis. The sample o…
Permissiveness toward tobacco sponsorship undermines tobacco control support in Africa
School personnel, who are respected members of the community, may exert significant influence on policy adoption. This study assessed the impact of school personnel's permissiveness toward tobacco industry sponsorship activities on their support for complete bans on tobacco advertisements, comprehensive smoke-free laws and increased tobacco prices. Representative data were obtained from the Global School Personnel Survey for 29 African countries …
Exposure to secondhand smoke and voluntary adoption of smoke-free home and car rules among non-smoking South African adults
Over half of South African adults reported SHS exposure in the home or at public places such as the workplace and at hospitality venues. This underscores the need for comprehensive smoke-free laws that prohibit smoking in all public indoor areas without exemptions
Poverty and Substance Use in South African Tuberculosis Patients
Poverty alleviation and social support-based interventions may benefit male TB patients with substance use
A Comparison of Cessation Counseling Received by Current Smokers at US Dentist and Physician Offices During 2010–2011
Objectives. We compared patient-reported receipt of smoking cessation counseling from US dentists and physicians. Methods. We analyzed the 2010 to 2011 Tobacco Use Supplement of the Current Population Survey to assess receipt of smoking cessation advice and assistance by a current smoker from a dentist or physician in the past 12 months. Results. Current adult smokers were significantly less likely to be advised to quit smoking during a visit to …
Health Insurance, Socio-Economic Position and Racial Disparities in Preventive Dental Visits in South Africa
Reporting making routine yearly PDVs as a preventive measure. Education, material wealth index and nutritional status indicated socio-economic position. Multi-level logistic regression analysis was conducted to determine the predictors of PDVs. A variant of Blinder-Oaxaca decomposition analysis was also conducted. Health insurance coverage was most common among Whites (70%) and least common among black Africans (10.1%) in South Africa. Similarly,…
Influence of Rural Non-Smoking Adolescents’ Sense of Coherence and Exposure to Household Smoking on Their Commitment to a Smoke-Free Lifestyle
This 18-month longitudinal study examined the influence of adolescents' sense of coherence (SOC) and exposure to household smoking on their commitment to a smoke-free lifestyle. This study investigated a representative sample of 8th graders from 21 randomly selected high schools in the rural Limpopo Province of South Africa (n = 2,119). Of the total sample of 2,119 participants, 294 (14%) reported smoking at baseline and were therefore excluded f…
Tobacco use patterns in tuberculosis patients with high rates of human immunodeficiency virus co-infection in South Africa
Despite documented evidence of its harmful effects, smoking is prevalent among male TB patients in this high HIV-prevalence population. Few patients have managed to quit smoking on their own. However, patients are highly motivated to stop smoking. We recommend implementing and evaluating a smoking cessation programme in tandem with TB services
Roll-your-own’ cigarette smoking in South Africa between 2007 and 2010
Despite an aggregate decline in smoking prevalence, roll-your-own cigarette smoking has increased and is particularly common among smokers in the lower socio-economic group. The findings also suggest the need for a more intensive treatment intervention to increase self-efficacy to quit among roll-your-own cigarette smokers
Socio-Environmental Factors Associated with Self-Rated Oral Health in South Africa
The findings highlight the potential role of social capital in improving the population's oral health
Dual Use of Cigarettes and Smokeless Tobacco Among South African Adolescents
Dual tobacco use forms part of multiple-risk-taking behavior
Tobacco smoke pollution in the ‘non-smoking’ sections of selected popular restaurants in Pretoria, South Africa
Exposure to second-hand tobacco smoke (SHS) has been associated with several adverse \n health effects including increased risk of lung cancer, heart disease and also asthma in \n children. Hence, the WHO's Framework Convention on Tobacco Control (FCTC) obligates \n parties to the Convention, to implement measures to protect all people from the exposure to \n SHS. Even prior to signing the WHO FCTC in 2005, the South African government in 2001 \n…
Global surveillance of oral tobacco products
These data have important implications for risk assessment because they show that very different exposure risks may be posed through the use of these chemically diverse oral tobacco products. Because of the wide chemical variation, oral tobacco products should not be categorised together when considering the public health implications of their use
Applying toxicological risk assessment principles to constituents of smokeless tobacco products
This study's findings provide an empirical risk assessment that could guide STP regulation using an existing toxicological assessment framework. The study findings question the scientific rationale of the industry-set standards and highlight the need for regulatory actions to reduce specific toxicants in all STPs
Association of snuff use with chronic bronchitis among South African women
These data suggest that snuff use, in the form predominantly used in South Africa, increases the risk of CB. This challenges the idea that snuff may be a much less harmful alternative to smoking in South Africa

Nicotine delivery capabilities of smokeless tobacco products and implications for control of tobacco dependence in South Africa
South African SLT users are mostly exposed to potentially very highly addictive levels of nicotine that may favour tobacco dependence and its consequent health risks. The increasing use of SLT by women of childbearing age support the need for intensified policy action to control its use
