The effect of smokeless tobacco use and exposure to cigarette promotions on smoking intention among youths in Ghana

Cigarette Prices and Smoking Experimentation Among Zimbabwean Children: A Survival Analysis of the 2014 Global Youth Tobacco Survey

INTRODUCTION

Zimbabwe has a smoking prevalence of 11.7% among the adult population (15 years and older). Thus, in the absence of effective tobacco control measures, the economic burden of tobacco use will be aggravated, especially considering the increasing tobacco industry activity in the country. Increasing cigarette prices is one possible strategy to reduce tobacco consumption. This study seeks to examine the relationship between cigarette prices and smoking experimentation among children in Zimbabwe, thereby expanding the evidence base for the likely impact of excise taxes on cigarette demand in low- and middle-income countries.

AIMS AND METHODS

A survival analysis using the Zimbabwe 2014 Global Youth Tobacco Survey data.

RESULTS

A 10% increase in the price of cigarettes reduces the probability of experimenting with smoking by 9%. Also, children are more likely to experiment with smoking if they have a smoking brother or father who smokes, or see teachers who smoke. The likelihood of experimenting with smoking is higher among boys than girls and is positively associated with age.

CONCLUSIONS

There is strong evidence that increasing excise taxes can play an effective role in discouraging children from experimenting with cigarette smoking. Considering the relatively low excise tax burden in Zimbabwe, the government should consider substantially increasing the excise tax burden.

IMPLICATIONS

With the number of smokers in low- and middle-income countries expected to increase as the industry intensively expands its market by targeting the youth, increasing excise taxes will play a significant role in preventing children from initiating smoking and help those who are already using tobacco to quit. An increase in the excise tax increases the retail price of tobacco products, making them less affordable, and reduces the demand for them.

Disparities in self-reported exposure to tobacco marketing among youth and young adults from low-socioeconomic status neighbourhoods in Mexico City

Exposure to tobacco marketing is positively associated with smoking initiation and behaviours. There is limited literature examining disparities among reported exposure in low- and middle-income countries. This study sought to fill this gap with a survey among 1427 adolescents and 889 adult smokers in Mexico City in 2020. Data were analysed using chi-square and hierarchical regression models. Two-thirds of adolescents noticed cigarette pack displays in stores. Participants from low- and mid-socioeconomic status (SES) neighbourhoods were more exposed to tobacco marketing than their counterparts through several channels. After addressing the shared variance among participants from the same household nested in neighbourhood SES level and controlling for gender, adolescent non-smokers and adult smokers who noticed pack displays were more likely to be susceptible to smoking (OR = 1.8, 95% CI 1.4-2.4) and to smoke more (OR = 1.7, 95% CI 1.21-2.47); adult smokers who noticed tobacco marketing at more places were less likely to be certain about smoking risks (OR = 0.9, 95% CI 0.8-0.9). The results suggest that the tobacco industry targets youth and individuals from low-SES neighbourhoods through several channels. Greater exposure to tobacco marketing was associated with increased susceptibility to smoking and decreased risk perception. These findings support a comprehensive ban on tobacco marketing in Mexico.

Effect of price on the decision to experiment with cigarette smoking among Gambian children: a survival analysis using the Gambia 2017 Global Youth Tobacco Survey data

OBJECTIVES

To investigate the relationship between cigarette prices and smoking experimentation among children in the Gambia, and thereby expanding the evidence base of the likely impact of excise taxes on cigarette demand in low-income and middle-income countries.

DESIGN

A survival analysis using the Gambia 2017 Global Youth Tobacco Survey data.

SETTING

The Gambia.

PARTICIPANTS

The survey sample was 12 585 youths, aged 12-17 years, but our analysis was restricted to 11 030 respondents with information on smoking status.

PRIMARY AND SECONDARY OUTCOME MEASURES

Our outcome variable was smoking experimentation defined as the first time the respondent smoked (at least part of) a cigarette.

RESULTS

A 1% increase in the price of cigarettes reduces the probability to experiment with smoking by 0.7%. We also found that children are more likely to experiment with smoking if they have at least one smoking parent, friends who smoke and see teachers who smoke. The probability to experiment with cigarette smoking increases with age and is higher among boys than girls.

CONCLUSION

There is strong evidence that increasing excise taxes can play an effective role in discouraging children from experimenting with cigarette smoking. Considering the relatively low excise tax burden in the Gambia, the government should consider substantially increasing the excise tax burden.

Smokeless tobacco consumption and its association with tobacco control factors in the Western Pacific Region: results from the Global Youth Tobacco Survey 2015-2019

OBJECTIVES

We estimated the prevalence of smokeless tobacco (ST) consumption and its associations with tobacco control factors among school-going youth in 18 Western Pacific Region (WPR) countries.

METHODS

We analyzed school-based Global Youth Tobacco Survey (2014-2019) microdata from 18 WPR countries and estimated weighted prevalence rates of ST consumption, cigarette smoking, and dual use. We used multilevel binary logistic regression to examine the associations of ST consumption and dual use with demographic variables, exposure to pro-tobacco and anti-tobacco factors, national income, and MPOWER indicators.

RESULTS

Data from 58,263 school-going youth were analyzed. The prevalence of past 30-day ST consumption was highest in Kiribati (42.1%), the Marshall Islands (26.1%), Micronesia (21.3%), Palau (16.0%), and Papua New Guinea (15.2%). In adjusted multilevel models, ST consumption and dual use were significantly associated with sex, age, parental smoking, pro-tobacco factors, national income, and MPOWER score. For each unit increase in score for cessation programs, we observed approximately 1.4-fold increases in the odds of youth ST consumption (adjusted odds ratio [aOR], 1.38; 95% confidence interval [CI], 1.15 to 1.66) and dual use (aOR, 1.47; 95% CI, 1.16 to 1.86). Similarly, for each unit increase in score for health-related warnings, the odds of both ST consumption (aOR, 0.47; 95% CI, 0.42 to 0.53) and dual use (aOR, 0.35; 95% CI, 0.30 to 0.42) decreased by approximately 60%.

CONCLUSIONS

The prevalence of youth ST consumption was substantial in the Pacific Islands, exceeding that of cigarette smoking in some countries. Implementing MPOWER measures for ST products could help reduce ST consumption.

Effect of relative income price on smoking initiation among adolescents in Ghana: evidence from pseudo-longitudinal data

OBJECTIVE

Many smokers initiate smoking during adolescence. Making tobacco products less affordable is one of the best ways to control tobacco use. Studies on the effect of relative income price (RIP (ie, affordability)) of cigarettes on smoking initiation are scarce in low-income and middle-income countries, especially in Sub-Saharan Africa where data are limited. The goal of this study is to examine the effect of cigarette RIP on adolescent smoking initiation in Ghana.

SETTING

The study uses a pseudo-longitudinal data set constructed from the Global Youth Tobacco Surveys (GYTS (2000-2009 and 2017)) and RIP for the most sold cigarette brand in Ghana.

PARTICIPANTS

The GYTS is a national survey on adolescents.

PRIMARY AND SECONDARY OUTCOME

Effect of RIP on adolescent smoking initiation in Ghana.

RESULTS

Using the GYTS 2000-2009 data, we find that the probability of smoking initiation falls significantly in response to a higher RIP, with an elasticity of -0.372 (95% CI -0.701 to -0.042) for the unmatched sample and -0.490 (95% CI -0.818 to -0.161) for the matched sample. The RIP elasticity for women ((-0.888) (95% CI -1.384 to -0.392) and (-0.928) (95% CI -1.434 to -0.422)) is statistically significant at 1% in both the unmatched and the matched samples, respectively, while the RIP elasticity for men is statistically insignificant in the 2000-2009 surveys. Analysis of the 2017 GYTS shows a similar outcome: a negative relationship between RIP and smoking initiation, and the results are statistically significant for both men and women, and for both matched and unmatched samples.

CONCLUSION

The affordability (RIP) of cigarettes is negatively related to the probability of smoking initiation among adolescents in Ghana. Raising tobacco taxes in line with income growth would make cigarettes less affordable and dissuade adolescents from initiating smoking.
