[Smoking prevalence in Portuguese school-aged adolescents by gender: can we be optimistic?]

O consumo de tabaco pelos pais e filhos: Um estudo numa escola do interior alentejano

A exposição ao fumo ambiental do tabaco (FAT) representa um risco acrescido para a saúde pública. É nas suas próprias casas que as crianças correm maior risco de exposição ao FAT, em especial quando a mãe ou o pai são fumadores. Este estudo procurou conhecer a prevalência de crianças e jovens de uma escola do interior da região Alentejo expostas ao FAT. Aplicou-se um questionário a uma amostra de 141 alunos. Os resultados revelam que são em menor número os pais que fumam em casa dos alunos mais novos.

Smoking among adolescents is associated with their own characteristics and with parental smoking: cross-sectional study

BACKGROUND

This study aimed to analyze the association between smoking during adolescence and the characteristics of smoking and alcohol consumption among their parents.

DESIGN AND SETTING

Cross-sectional study in Londrina (PR), Brazil.

METHODS

The subjects comprised 1,231 adolescents aged 14-17 years. The adolescents and their parents answered a self-report questionnaire that asked for sociodemographic information and data on smoking and alcohol consumption. Multiple logistic regression models were used to analyze associations between smoking among adolescents and their characteristics (age, sex, period of the day for attending school, alcohol consumption and socioeconomic level) and their parents' characteristics (smoking, alcohol consumption, age and education level), adjusted according to the adolescents' characteristics (sex, age and socioeconomic level).

RESULTS

The prevalence of smoking among adolescents was 3.4% (95% confidence interval, CI: 2.4-4.4). Adolescents whose mothers or fathers were smokers were 2.0 and 2.5 times more likely to be smokers, respectively. The prevalence of smoking among adolescents with a smoking mother was 7.1% (95% CI: 2.6-10.7) and a smoking father, 5.4% (95% CI: 1.6-8.5). There were significant associations between smoking adolescents and age [5.2% (95% CI: 3.3-6.6)], studying at night [9.6% (95% CI: 4.0-15.5)] and alcohol consumption [69.0% (95% CI: 55.0-83.0)]. It was observed that the number of alcoholic beverage doses consumed was higher among smoking adolescents (P = 0.001).

CONCLUSION

Adolescent smoking was associated with smoking by their parents, regardless of the gender of the parents or adolescents. Age, alcohol consumption and studying at night are characteristics of adolescents that can contribute towards smoking.

Prevalence of and factors influencing smoking among medical and non-medical students in Tbilisi, Georgia

OBJECTIVE:

Smoking is a serious problem that has a devastating impact on health. The objective of this study was to describe the prevalence of and factors influencing smoking among medical and non-medical students in Tbilisi, Georgia, as well as to determine whether medical education has an impact on smoking.

METHODS:

A cross-sectional study was carried out at Tbilisi State Medical University and Tbilisi State University, both of which are located in Tbilisi, Georgia. A total of 400 4th-year students (200 students at each university) were asked to complete standardized questionnaires.

RESULTS:

Of the sample as a whole, 48.75% were identified as smokers and 51.25% were identified as nonsmokers. The mean age was 20.24 years among smokers and 20.26 years among nonsmokers. Of the medical students, 49.5% were smokers, as were 48.0% of the non-medical students. The male-to-female ratio in the study population was 0.9:1.1. Smoking was found to have a strong relationship with gender, males accounting for 65% of all smokers. Of the smokers, 56.9% stated that they would like to quit smoking (for health or financial reasons). Of the medical students, 59.5% expressed a willingness to quit smoking, as did 54.2% of the non-medical students.

CONCLUSIONS:

There is a need to improve smoking education for undergraduate students. Special attention should be given to the inclusion of anti-smoking education in undergraduate curricula, as well as to the implementation of smoking prevention campaigns at institutions of higher education. However, such measures will be effective only if tobacco control policies are strictly enforced on the national level as well.
