Sociodemographic factors associated with smoking risk perception in adolescents in São Paulo, Brazil

Demographic and lifestyle factors associated with perception about risk of passive smoking in the Malaysian adolescent population

AIMS

Exposure to passive smoking among adolescents is a public health concern. This study aims to explore demographic and lifestyle factors associated with perception of passive smoking risk and the mediating effects of exposure to anti-smoking advertisements and education about the dangers of smoking on the relationship between grade levels and the perception.

METHOD

Data from the Tobacco and E-Cigarette Survey among Malaysian Adolescents (n = 13,117) were analysed. Ordered probit models were used to assess factors associated with passive smoking risk perception (i.e. not harmful, probably not harmful, probably harmful, harmful).

RESULTS

About one-third of adolescents did not perceive that passive smoking was harmful (30.4%). Adolescents with the perception that passive smoking was not harmful were more likely to be students at low grade levels, be males, be non-Malays and be low-pocket-money recipients and those who used e-cigarettes and who smoked. Being aware of anti-smoking advertisements (direct effect = 0.174; indirect effect = 0.012) and taught on the dangers of smoking (direct effect = 0.179; indirect effect = 0.003) partially mediated the positive relationship between grade levels and perceived risk of passive smoking.

CONCLUSION

Policies implemented to reduce exposure to passive smoking should highlight the important role of demographic factors, lifestyle profiles, anti-smoking advertisements and education about the dangers of smoking in improving passive smoking risk perception among adolescents.

Knowledge of smoking and influencing factors among school-going adolescents in Timor-Leste

OBJECTIVES

Knowledge of smoking is a protective factor for adolescent smoking. This study is the first to examine sociodemographic and lifestyle factors associated with adolescents' knowledge of smoking in Timor-Leste. It is also a pioneering investigation into the ways in which exposure to anti-tobacco messages and health warnings on cigarette packages, and involvement in smoking-related education at schools and home mediate the relationship between school grade levels and smoking knowledge.

METHODS

Data were obtained from the Global Youth Tobacco Survey Timor-Leste. Ordered logistic regressions were used to examine the associations between knowledge of smoking and sociodemographic, and lifestyle factors. Structural equation modelling was utilized to explore the mediating effects.

RESULTS

Adolescents were less likely to have high knowledge of smoking if they were lower-secondary students, were males, had unemployed parents and had no closest friends who smoked. The relationship between grade levels and smoking knowledge was partly mediated by awareness of anti-tobacco messages on mass media, school education about the dangers of smoking and family discussion about smoking.

CONCLUSIONS

Sociodemographic and lifestyle factors play an important role in determining knowledge of smoking among adolescents. To some extent, awareness-, education- and family-related variables explain how grade levels affect smoking knowledge.

Parenting and Courage: Exploring the Mediating Role of Self-esteem and Emotion Regulation among Adolescents

With adolescence being a period for potential challenges but also positive growth, courage can aid adolescents in rising to some of these challenges. Yet few studies have investigated predictors and mechanisms of courage. The present study examined how three parenting constructs (attachment, autonomy support, and helicopter parenting) predict courage and if self-esteem or emotion regulation serve as mediators. The present study assessed predictors at Time 1 and courage at one-year follow-up. The sample included 203 American adolescents (51.7% girls, 14-15 year olds). Results suggested that relations between several parental variables (anxious attachment to parents, avoidant attachment to fathers, autonomy support of parents) and adolescent courage were mediated by self-esteem. In addition, cognitive reappraisal mediated associations between two mother-related variables (avoidant attachment, helicopter parenting) and courage. Findings contribute to the limited empirical research on adolescents' development of courage.

Association between secondhand smoke exposure in pregnant women and their socioeconomic status and its interaction with age: a cross-sectional study

Background

Existing evidence highlights that exposure to secondhand smoke (SHS) is a risk factor for pregnant women’s health and is possibly affected by individual characteristics. This study aimed to explore the effect of individual socioeconomic status (SES) on SHS exposure among pregnant women in the third trimester and the interaction effect of age.

Methods

A total of 678 nonsmoking pregnant women with a median age of 29.0 years from 14 communities in a medium-sized city were recruited for this survey. Exposure to SHS was defined as the self-reported smoking habit of a spouse/partner. Individual SES characteristics consisted of marital status, educational attainment, employment and per capita monthly income.

Results

There were 238 (35.1%) participants who suffered from SHS exposure. Compared to the pregnant women who were employed, those who were unemployed were more likely to suffer from SHS exposure (OR = 1.572, 95% CI: 1.013–2.441). Participants who had a high school or technical secondary school education were more likely to be exposed to SHS than those with a college education or above (OR = 1.601, 95% CI: 1.029–2.449). Advanced age was a protective factor for participants with a college education or above (OR = 0.939, 95% CI: 0.884–0.997), but age increased the risk of SHS exposure among women who had unstable marriages (OR = 1.256, 95% CI: 1.019–1.549).

Conclusion

Exposure to SHS was very common among pregnant women in the third trimester. Pregnant women with a low SES and an older age should be considered a key population for the implementation of public health interventions.
