Perceived effectiveness of graphic health warnings as a deterrent for smoking initiation among adolescents in selected schools in southwest Nigeria

A Scoping Review of Tobacco Control Health Communication in Africa: Moving towards Involving Young People

Health communication has been highlighted as a cost-effective preventive intervention in Africa, where the prevalence of tobacco use is still relatively low compared to other World Health Organization (WHO) regions. This scoping review aimed to examine tobacco control health communication interventions in Africa. The review was guided by the PRISMA-ScR checklist. Data was extracted from 20 peer-reviewed papers, WHO Global Health Observatory on anti-tobacco mass-media campaigns for 54 African countries, and 6 WHO Framework Convention on Tobacco Control reports on Article 12. Data extraction informed by the Joanna Briggs Institute (JBI) data-extraction questions was used for peer-reviewed studies while a pre-determined template was used for the other sources. Narrative data synthesis informed by the JBI manual for evidence synthesis was employed. A lack of research that comprehensively addresses all areas of health communication and inconsistent use of health communication campaigns were identified. Only an average of 6 countries had ever implemented high-quality national mass-media campaigns in a decade, while an average of 33 countries consistently failed to conduct campaigns that lasted more than 3 weeks. Although the involvement of key populations was clearly vital to ensure content relevance and message clarity, a lack of health communication informed by young people was observed, as they rarely participated in key decision-making despite reportedly being the targets of interventions. Clear health communication for tobacco-use prevention informed by young people is lacking in African countries. Active participation of young people in developing targeted campaigns is needed to facilitate content relevance and comprehension to ultimately contribute to tobacco-use prevention.

Effects of immediate and distant health consequences: different types of health warning messages on sweets affect the purchase probability

BACKGROUND

Several health control policies have been discussed as a regulatory approach to tackle the increasing prevalence of obesity and other health risks related to sugar consumption. Health warnings, like the ones used in tobacco control worldwide, are one of the most promising approaches. However, in the case of health warning messages for food products, it is much more complicated and involves much more consumer involvement than tobacco guidance. Therefore, it is important to better understand the efficacy, evaluation, and reactance of health warning labels in the food sector regarding consumers' behavior, persuasion, and perceptions. The aim of this study was to examine how different types (design and message) of health warning messages in combination with graphical applications affect consumer behavior.

METHODS

In a 3 × 3 × 3 symmetrical design, 1,040 German participants completed an online discrete choice experiment including various text-only and image-and-text health warning labels on sweets. An accompanying questionnaire assessed socio-demographic variables as well as psychometric scales to understand the relationship between fear, control, reactance, and shocking/inhibiting/mediating health-related warnings.

RESULTS

Our results suggest that especially emotional graphical images combined with text health warning labels might be more influential. The health effects of immediate (caries) and more distant health consequences (diabetes/obesity) differ in their impact. Further, results show that especially when consumers engage in a danger control process for overweight, warning messages have a negative impact on their choices.

CONCLUSION

Hence, warning labels on sweets can potentially be a decisive factor when communicating health threats related to excessive sugar consumption. In the context of a targeted health policy, we see the need for further research, especially concerning the perception and understanding of noncommunicable diseases (NCDs) in the population.

Quasi-experimental evaluation of Kenya's pictorial health warnings versus Zambia's single text-only warning: findings from the International Tobacco Control (ITC) Project

BACKGROUND

Population studies in mostly high-income countries have shown that pictorial health warnings (PHWs) are much more effective than text-only warnings. This is the first quasi-experimental evaluation of the introduction of PHWs in Africa, comparing the change from text-only to PHWs in Kenya to the unchanged text-only health warning in Zambia.

METHODS

Data were from International Tobacco Control (ITC) Surveys in Kenya (n=1495), and Zambia (n=1628), cohort surveys of nationally representative samples of adult smokers in each country. The ITC Kenya Survey was conducted in 2012 and 2018 (2 years after the 2016 introduction of three PHWs). The ITC Zambia Survey was conducted in 2012 and 2014 with no change to the single text-only warning. Validated indicators of health warning effectiveness (HWIs) (salience: noticing, reading; cognitive reactions: thinking about health risks, thinking about quitting; and behavioural reactions: avoiding warnings; forgoing a cigarette because of the warnings), and a summary measure-the Labels Impact Index (LII)-measured changes in warning impact between the two countries.

RESULTS

PHWs implemented in Kenya led to a significant increase in all HWIs and the LII, compared with the text-only warning in Zambia. The failure to implement PHWs in Zambia led to a substantial missed opportunity to increase warning effectiveness (eg, an estimated additional 168 392 smokers in Zambia would have noticed the warnings).

CONCLUSIONS

The introduction of PHWs in Kenya substantially increased the effectiveness of warnings. These results provide strong empirical support for 34 African countries that still have text-only warnings, of which 31 are Parties of the Framework Convention on Tobacco Control and are thus obligated to implement PHWs.

Country Participation in the WHO Framework Convention on Tobacco Control Health Warnings Database

Background

The World Health Organization’s (WHO) Framework Convention on Tobacco Control (FCTC) Health Warnings Database is an online, publicly available resource created for countries to upload and share pictorial health warnings for tobacco packaging. The purpose of this study was to evaluate the extent to which the database is used by countries for the sharing of pictorial warnings.

Methods

The study’s sample included parties to the FCTC who required graphic health warning labels on cigarette packaging from. Those countries were categorized as having a low, middle, and high Socio-Demographic Index (SDI). The Health Warnings Database was then analyzed for those countries’ unique pictorial images, as well as the number of pictorials that were shared between countries.

Results

Of the 110 countries that required pictorial warnings on cigarette packaging, only 53 (48%) voluntarily contributed pictorials to the database, with most of those (53%) being high SDI-level countries. There were 342 unique pictorials on the database, with 62 images posted by seven countries that were used by 13 other countries.

Conclusion

While sharing was evident from the database, there remains a need for more countries to upload the pictorials to the database. There is also a need to expand the database to include alternative tobacco products, such as waterpipe tobacco and e-cigarettes.

Impact of tobacco-pack pictorial warnings on youth and young adults: A systematic review of experimental studies

INTRODUCTION

We conducted a systematic review of the experimental literature on the impact of tobacco-pack pictorial warning labels (PWLs) on youth and young adults.

METHODS

We systematically searched computerized databases and the reference lists of relevant articles. We included studies that used an experimental protocol to assess PWLs. Studies had to report findings for youth or young adult samples (aged <30 years). Thirty-one studies met the inclusion criteria, with a total sample size of 27506. Two coders independently coded all study characteristics and outcomes.

RESULTS

Twenty-eight studies experimentally evaluated PWLs for cigarette packs while three studies evaluated PWLs for smokeless tobacco packs. Generally, PWLs led to higher attention, stronger cognitive and affective reactions, more negative pack attitudes and smoking attitudes, and increased intentions not to use tobacco products compared to text warnings. PWLs were perceived to be more effective than text warnings for both cigarette packs and smokeless tobacco packs.

CONCLUSIONS

The systematic review showed that PWLs on tobacco products are effective across a wide range of tobacco-related outcomes among young people. Gaps in the literature include a lack of research on tobacco initiation and cessation and a dearth of literature on non-cigarette tobacco products.

A systematic review of the perceptions of adolescents on graphic health warnings and plain packaging of cigarettes

BACKGROUND

Graphic health warnings on tobacco packaging and the plain packaging of tobacco products are key tobacco control interventions. This systematic review investigates the perceptions of adolescents towards these packaging interventions.

METHODS

Published, original-research, English-language articles from 1 January 2000 to 1 September 2017 were identified through a systematic literature search of the PubMed, CINAHL, PsycINFO, Web of Science, and Scopus databases. Articles describing investigations into the perceptions of adolescents aged 11 to 19 years towards graphic health warnings and/or plain-packaged cigarettes were included in this review.

RESULTS

Nineteen articles, involving 15,935 adolescent participants, of which 72.85% were non-smokers or ex-smokers and 27.15% occasional or daily smokers, met the eligibility criteria. Graphic health warnings were perceived as more effective than text-only warnings, with warnings depicting lung cancer, and oral diseases being perceived as particularly effective. Health warnings increased viewer fear, anxiety, shock, and guilt and were considered effective in preventing non-smokers from experimenting with tobacco and prompting current smokers to quit. Plain packaging reduced the attractiveness and other positive attributes of cigarette packaging, with darker colours found to be the most effective. When used in combination, plain packaging increased the visibility of graphic health warnings, with participants also perceiving them as having an increased tar content and having more serious health risks, and increased thoughts of quitting amongst smokers.

CONCLUSIONS

Graphic health warnings and plain packaging appear to increase adolescent awareness of the dangers of tobacco use. Further research into the most effective warnings to use in combination with plain packaging is needed to ensure the greatest reduction in tobacco use and prevent tobacco-attributable morbidity and mortality in this vulnerable population.

Analysis of tobacco control policies in Nigeria: historical development and application of multi-sectoral action

BACKGROUND

Tobacco use is a major risk factor for non-communicable diseases and policy formulation on tobacco is expected to engrain international guidelines. This paper describes the historical development of tobacco control policies in Nigeria, the use of multi-sectoral action in their formulation and extent to which they align with the World Health Organisation "best buy" interventions.

METHODS

We adopted a descriptive case study methodology guided by the Walt and Gilson Policy Analysis Framework. Data collection comprised of document review (N = 18) identified through search of government websites and electronic databases with no date restriction and key informant interviews (N = 44) with stakeholders in public and private sectors. Data was integrated and analyzed using content analysis. Ethical approval was granted by the University of Ibadan and University College Hospital Ethics Review Committee.

RESULTS

Although the agenda for development of a national tobacco control policy dates back to the 1950s, a comprehensive Framework Convention for Tobacco Control (FCTC) compliant policy was only developed in 2015, 10 years after Nigeria signed the FCTC. Lack of funding and conflict of interest (of protecting citizens from harmful effect of tobacco viz. a viz. the economic gains from the industry) are the major barriers that slowed the policy process. Current tobacco -related policies developed by the Federal Ministry of Health were formulated through strong multi-sectoral engagement and covering all the four WHO "best buy" interventions. Other policies had limited multi-sectoral engagement and "best buy" strategies. The tobacco industry was involved in the development of the Standards for Tobacco Control of 2014 contrary to the long-standing WHO guideline against engagement of the industry in policy formulation.

CONCLUSIONS

Nigeria has a comprehensive national policy for tobacco control which was formulated a decade after ratification of the FCTC due to constraints of funding and conflict of interest. Not all the tobacco control policies in Nigeria engrain the principles of multisectorality and best buy strategies in their formulation. There is an urgent need to address these neglected areas that may hamper tobacco control efforts in Nigeria.

Australian community pharmacist experiences with smoking cessation and opinions of health warnings on individual cigarette sticks

OBJECTIVES

We aimed to identify the experiences of Australian community pharmacists with smokers and their associated perceptions of effective health warnings on individual cigarette sticks.

METHODS

A mixed-methods online survey was distributed to Australian pharmacists through pharmacy-specific social media pages, and the Pharmaceutical Society of Australia, followed by semi-structured face-to-face interviews with pharmacists in Townsville, Australia, who were purposively sampled. The interviews continued until data saturation was achieved. Participants described their experiences with smokers, perceptions and effectiveness ratings of current cigarette packaging warnings, and 12 text warnings (divided into four themes) on individual cigarette sticks, and their general opinions on effective anti-tobacco health warnings.

KEY FINDINGS

Seventy pharmacists participated in the survey and 17 pharmacists in the interviews. Both groups of pharmacists cited smoking-related personal or close-contact illness, pressure by family members or physicians and the financial costs of smoking as being the main drivers for quit attempts. Most interviewed pharmacists interact with smokers several times per week. Cigarette stick warnings describing mortality consequences (especially the 'minutes of life lost' warning) and the financial consequences of tobacco use were rated as significantly more effective than current packaging warnings (odds ratio [OR] = 2.23; 95% confidence interval [CI]: 1.12-4.12, P = 0.02, and 1.97; 95%CI: 1.01-3.84, P = 0.04, respectively).

CONCLUSIONS

Pharmacists have considerable experience assisting smokers with quitting and based on these experiences believe that novel and tangible health warnings on cigarette sticks may be an effective future measure to combat tobacco use. Further research on the opinions of a more diverse range of health professionals and the general community will generate more robust findings regarding this method of intervention.

Factors Affecting the Perceived Effectiveness of Pictorial Health Warnings on Cigarette Packages in Gulf Countries: A Cross-sectional Study

Objectives:

To explore the perceived effectiveness of pictorial health warning (PHW) labels required by the Gulf Cooperation Council, to compare them with the Food and Drug Administration–approved PHW labels, and to determine factors affecting their perceived effectiveness.

Methods:

A cross-sectional study using a convenience sample of adult smokers and nonsmokers was conducted. The data were collected through a self-administered online questionnaire. The perceived effectiveness scores of PHW labels were calculated and compared among different subgroups using the Kruskal-Wallis test and the Dunn multiple comparison test at a .05 significance level.

Results:

Of the 90 people invited to participate in the survey, 77 (86%) completed it, with 39 (50%) nonsmokers, 22 (29%) smokers, and 16 (21%) former smokers. Overall, labels having graphic images of illness or pathology are perceived to be most effective. Smokers generally perceived labels significantly less effective compared with former smokers and nonsmokers. Also, 55 respondents (71%) suggested that the presence of a telephone quit-line would be effective.

Conclusions:

Smoking status and image type had the most effect on the perceived effectiveness of the PHW labels on cigarette packs. Pictorial health warning labels with graphic images of pathology and a telephone quit-line are perceived to be most effective.

Global Cancer in Women: Cancer Control Priorities

This review is an abbreviated version of a report prepared for the American Cancer Society Global Health department and EMD Serono, Inc., a subsidiary of Merck KGaA, Darmstadt, Germany, which was released at the Union for International Cancer Control World Cancer Congress in Paris in November 2016. The original report can be found at https://www.cancer.org/health-care-professionals/our-global-health-work/global-cancer-burden/global-burden-of-cancer-in-women.html. Staff in the Intramural Research Department of the American Cancer Society designed and conducted the study, including analysis, interpretation, and presentation of the review. The funding sources had no involvement in the study design, data analysis and interpretation, or preparation of the reviewThe global burden of cancer in women has recently received much attention, but there are few comprehensive reviews of the burden and policy approaches to reduce it. This article, second in series of two, summarizes the most important cancer control priorities with specific examples of proven interventions, with a particular focus on primary prevention in low- and middle-income countries (LMIC). There are a number of effective cancer control measures available to countries of all resource levels. Many of these measures are extremely cost-effective, especially in the case of tobacco control and vaccination. Countries must prioritize efforts to reduce known cancer risk factors and make prevention accessible to all. Effective treatments and palliative care are also needed for those who develop cancer. Given scarce resources, this may seem infeasible in many LMICs, but past experience with other diseases like HIV, tuberculosis, and malaria have shown that it is possible to make affordable care accessible to all. Expansion of population-based cancer registries and research in LMICs are needed for setting cancer control priorities and for determining the most effective interventions. For LMICs, all of these activities require support and commitment from the global community.
