Electronic cigarette (e-cigarette) and narghile use is increasing in Brazil, with younger, higher socioeconomic status individuals being more likely to use them than traditional cigarette users. Public health strategies should target youth for both e-cigarette and narghile prevention.
Area of Science:
- Public Health
- Epidemiology
- Tobacco Control
Background:
- Cigarette smoking prevalence is declining, but novel tobacco products like electronic cigarettes (e-cigarettes) and narghile are emerging.
- Narghile sales are legal in Brazil, while e-cigarette sales are prohibited, necessitating accurate prevalence data for monitoring.
- Understanding the use of these alternative tobacco products is crucial for effective public health interventions.
Purpose of the Study:
- To determine the prevalence of e-cigarette and narghile use in Brazil.
- To investigate sociodemographic differences between users of e-cigarettes, narghile, and manufactured cigarettes.
- To identify risk factors associated with the use of these tobacco products.
Main Methods:
- A nationally representative survey of Brazilians aged 12-65 years was conducted in 2015.
- Prevalence rates were estimated for e-cigarettes, narghile, and manufactured cigarettes within the past 12 months.
- Multivariable logistic regression models analyzed determinants of use, accounting for complex sample design and stratifying by various sociodemographic factors.
Main Results:
- Prevalence rates were 0.43% for e-cigarettes (0.6 million users), 1.65% for narghile (2.5 million users), and 15.35% for cigarettes (23.5 million users).
- Non-heterosexual individuals showed higher risk for all tobacco product use. E-cigarette/narghile users were younger and had higher socioeconomic status than cigarette users.
- Youthful recent cigarette use was more associated with e-cigarette/narghile use compared to adults.
Conclusions:
- Findings provide critical data on e-cigarette and narghile use patterns in Brazil.
- Integrated prevention strategies targeting youth for both narghile and e-cigarette use are recommended.
- These combined strategies may help prevent a new generation of tobacco users in Brazil.

Over the many stages of cellular respiration, glucose breaks down into carbon dioxide and water. Electron carriers pick up electrons lost by glucose in these reactions, temporarily storing and releasing them into the electron...
Electron Affinity
Electron Behavior
Electrons are negatively charged subatomic particles that are attracted to an orbit around the positively-charged nucleus of an atom. They reside in locations that are associated with energy levels called shells and are further organized into sub-shells and orbitals within each shell.
Electrons Orbit the Nucleus
Electrons are found in specific locations outside of the nucleus. The shell in which an electron resides indicates the general energy level of the electron: those closer to the...
