Electronic Cigarette and Heated Tobacco Product Use and Their Association With Tobacco Control Factors Among Adults in Indonesia, Kazakhstan, and the Philippines.

INTRODUCTION

Data on e-cigarette (EC) and heated tobacco product (HTP) use and the reasons for their use are useful for policy making. We report comparable nationally representative estimates of EC and HTP use and their associated factors.

AIMS AND METHODS

Global Adult Tobacco Survey data from Indonesia (2021), Kazakhstan (2019), and the Philippines (2021) were analyzed. The weighted prevalence rates and 95% CI of EC and HTP awareness, current use, and ever use, and their distribution by cigarette smoking status were calculated. Binary logistic regression analyses assessed socioeconomic, and tobacco control factors associated with EC and HTP use.

RESULTS

The prevalence (%) of EC awareness, ever use and current use were 48.7-69.4, 3.6-8.8, and 1.9-3.0, respectively. The prevalence(%) of HTP awareness, ever use and current use were 2.7-21.7, 0.2-2.1, and 0.1-1.2, respectively. The main reasons for EC and HTP use were attractive flavors(45.8%-73.9%), less harmful than smoking(23.0%-70.1%), and enjoyment(40.8%-76.7%). Avoiding going back to smoking(0.9%-54.4%) and quitting smoking(19.4%-49.8%) were less frequently cited reasons (except in the Philippines). EC/HTP use was associated with younger age, higher education and wealth, current/past smoking, exposure to information about the dangers of tobacco use, and advertisements about tobacco products and smoke-free rules at home.

CONCLUSIONS

The prevalence of EC and HTP use was higher among younger men with higher education and wealth, and current/past smoking. EC and HTP use should be closely monitored. Regulations to restrict the widespread marketing and sales of EC and HTP are needed to prevent the escalation of their use.

IMPLICATIONS

The population-level data provide the benchmark for future monitoring use of e-cigarettes and HTPs and identify population subgroups for future surveillance in low- and middle-income countries. The association of EC/HTP use with tobacco control-related factors provides leads for policies that should be formulated and implemented to regulate the product contents, marketing, and sales of EC and HTP.
