A focus on adolescent substance use in Europe, central Asia and Canada. Health Behaviour in School-aged Children international report from the 2021/2022 survey. Volume 3

The Health Behaviour in School-aged Children (HBSC) study is a large school-based survey carried out every four years in collaboration with the WHO Regional Office for Europe. HBSC data are used at national/regional and international levels to gain new insights into adolescent health and well-being, understand the social determinants of health and inform policy and practice to improve young people’s lives. The 2021/2022 HBSC survey data are accompanied by a series of volumes that summarize the key findings around specific health topics. This report, Volume 3 in the series, focuses on adolescent substance use, using the unique HBSC evidence on adolescents aged 11, 13 and 15 years across 44 countries and regions in Europe, central Asia and Canada. It describes the status of adolescent substance use (cigarette smoking, electronic cigarette use, alcohol consumption, drunkenness and cannabis use), the role of gender, age and social inequality, and how adolescent substance use has changed over time. Findings from the 2021/2022 HBSC survey provide an important evidence benchmark for current research, intervention and policy-planning.

Smoking is a Risk Factor for Generation Z, Too: The Evolution of the Attitudes.

Objectives: Generation Z, defined as "post-millennial," is considered to be the first generation that could end smoking. The objective is also to take into account the evolutionary aspect of the smoking and attitudes of the Generation Z. The aim of this study was to explore the willingness of Generation Z in Slovakia to comply with the legislation adopted in the field of anti-tobacco policy and to investigate some selected social factors-intention, subjective norm and percevied behavioral control-that contribute to a lower rate of compliance. Methods: Global Youth Tobacco Survey (GYTS) data on cigarette smoking among 3,557 adolescents (age range 13-15) in 2016 as well as on attitudes towards tobacco use and control measures were used to explore the level of compliance of adolescents with anti-tobacco regulations in Slovakia within the Framework Convention of Tobacco Control (FCTC). We used the concept of intention as explained in Ajzen's theory of planned behaviour (1985), focusing on the role of subjective norm and perceived behavioural control. Results: We found a decrease in ever smoking, current smoking and frequent smoking. We found that these adolescents start experimenting with dependence-causing substances, such as tobacco, regardless of existing rules. Conclusion: Adolescents were attracted to smoking, although they were aware of health effects of passive smoking, and a vast majority liked smoke-free places. They are also influenced by their peers and parental models.

Alcohol Use and Its Affordability in Adolescents in Slovakia between 2010 and 2018: Girls Are Less Adherent to Policy Measures.

BACKGROUND: The article analyzes selected indicators of alcohol use (weekly use, drunkenness within last month) and the ability of adolescents to buy alcohol in Slovakia between 2010 and 2018. METHODS: Health Behavior in School-Aged Children (HBSC) is a cross-sectional questionnaire study. A standardized uniform questionnaire was used to create a representative sample of 15-year-old adolescents. Two surveys carried out in Slovakia in 2010 (n = 1568) and 2018 (n = 1298) were analyzed. RESULTS: Weekly alcohol use and drunkenness declined only in boys, not in girls. Affordability of alcohol (not being prevented from buying it) declined among weekly drinking boys (from 60.4 to 34.1%) but remained almost unchanged in girls from a higher socioeconomic group compared to those from a lower one (57.9% vs. 30.6% in 2018). CONCLUSIONS: Affordability of alcohol in boys decreased with a decline in alcohol use, corresponding with implemented legislative measures. However, it remained unchanged in girls from a higher socioeconomic group.

Is educational differentiation associated with smoking and smoking inequalities in adolescence? A multilevel analysis across 27 European and North American countries.

This study aims to determine whether educational differentiation (i.e. early and long tracking to different school types) relate to socioeconomic inequalities in adolescent smoking. Data were collected from the WHO-Collaborative 'Health Behaviour in School-aged Children (HBSC)' study 2005/2006, which included 48,025 15-year-old students (Nboys = 23,008, Ngirls = 25,017) from 27 European and North American countries. Socioeconomic position was measured using the HBSC family affluence scale. Educational differentiation was determined by the number of different school types, age of selection, and length of differentiated curriculum at the country-level. We used multilevel logistic regression to assess the association of daily smoking and early smoking initiation predicted by family affluence, educational differentiation, and their interactions. Socioeconomic inequalities in both smoking outcomes were larger in countries that are characterised by a lower degree of educational differentiation (e.g. Canada, Scandinavia and the United Kingdom) than in countries with higher levels of educational differentiation (e.g. Austria, Belgium, Hungary and The Netherlands). This study found that high educational differentiation does not relate to greater relative inequalities in smoking. Features of educational systems are important to consider as they are related to overall prevalence in smoking and smoking inequalities in adolescence.

Socioeconomic inequalities in the impact of tobacco control policies on adolescent smoking. A multilevel study in 29 European countries.

INTRODUCTION: There are concerns that tobacco control policies may be less effective in reducing smoking among disadvantaged socioeconomic groups and thus may contribute to inequalities in adolescent smoking. This study examines how the association between tobacco control policies and smoking of 15-year-old boys and girls among 29 European countries varies according to socioeconomic group. METHODS: Data were used from the Health Behaviour in School-aged Children (HBSC) study conducted in 2005/2006 comprising 50,338 adolescents aged 15 years from 29 European countries. Multilevel logistic regression analyses were conducted to assess the association of weekly smoking with components of the Tobacco Control Scale (TCS), and to assess whether this association varied according to family affluence (FAS). Analyses were carried out per gender and adjusted for national wealth and general smoking rate. RESULTS: For boys, tobacco price was negatively associated with weekly smoking rates. This association did not significantly differ between low and high FAS. Levels of tobacco-dependence treatment were significantly associated with weekly smoking. This association varied between low and high FAS, with higher treatment levels associated with higher probability of smoking only for low FAS boys. For girls, no tobacco policy was significantly associated with weekly smoking, irrespective of the FAS. CONCLUSIONS: Results indicated that most tobacco control policies are not clearly related to adolescent weekly smoking across European countries. Only tobacco price seemed to be adequate decreasing smoking prevalence among boys, irrespective of their socioeconomic status.

Prevalence of youth cigarette smoking and selected social factors in 25 European countries: findings from the Global Youth Tobacco Survey.

OBJECTIVES: To present Global Youth Tobacco Survey (GYTS) data on the prevalence of cigarette smoking and selected social factors among students aged 13-15 years in 25 European countries. METHODS: The GYTS is a school-based survey of students aged 13-15 years. The GYTS was conducted in 25 European countries (2002-2005) and produced representative data for each country. RESULTS: In 25 European countries studied, 22% of boys and 18% of girls smoked cigarettes. In 17 of 25 countries, current cigarette smoking did not differ between boys and girls. Exposure to secondhand smoke is very high throughout the 25 countries. Exposure to pro-tobacco indirect advertising (having tobacco company logos on promotional items and being given free cigarettes) is frequent throughout the countries. CONCLUSIONS: Intensified efforts to lessen harm caused by tobacco use among youth in 25 European countries included in this study are urgently needed. These countries need to develop and implement comprehensive tobacco control programs including public education campaigns, cessation programs, enforcement of existing measures, and related policy efforts. The WHO FCTC provides a useful framework for implementing such a comprehensive approach.

Assessment of renal circulation in small for gestational age and appropriate for gestational age term newborns: a prospective study.

PURPOSE: To compare selected parameters of renal circulation between small for gestational age (SGA) and appropriate for gestational age (AGA) newborns. METHODS: Fifty-two SGA and 100 AGA term newborns were examined. The size of the kidneys were measured, and renal blood flow in the central and intraparenchymal renal arteries were assessed via Doppler sonography. Peak systolic velocity (PSV), end diastolic velocity (EDV), mean blood flow velocity (V mean), resistance index (RI), and pulsatility index (PI) were determined and compared between the groups. RESULTS: No statistically significant differences in the velocity parameters were found between SGA and AGA infants in central renal arteries. Slightly higher RIs and PIs were seen in AGA newborns (RI, 0.76 +/- 0.13 versus 0.78 +/- 0.06 [p < 0.05]; PI, 1.65 +/- 0.54 versus 1.84 +/- 0.46 [p < 0.05]). There were statistically significant differences between the groups in all measured parameters in intraparenchymal arteries (RI, 0.57 +/- 0.11 versus 0.63 +/- 0.05 [p < 0.001]; PI, 0.89 +/- 0.26 versus 1.09 +/- 0.16 [p < 0.001]) except PSV (7.11 +/- 1.55 versus 7.14 +/- 0.81 cm/s [p > 0.05]). CONCLUSION: Based on our findings, we suggest that renal circulation is not negatively influenced by intrauterine growth restriction in SGA neonates compared with AGA newborns.

Economic rewarding of smoking cessation-facilitating drugs--a comparison of over-the-counter and prescribed nicotine replacement therapy.

Smoking cessation represents a very difficult task for the smoker, often requiring medical assistance. The introduction of smoking cessation drugs has been crucial to this process. Currently, there are two standardly used treatments: nicotine replacement therapy (NRT) and the antidepressant bupropion. Soon after their introduction, NRTs were sold over-the-counter (OTC), as oppose to on prescription, although in most countries, bupropion remains available only on prescription. Both prescribed and OTC NRTs have similar efficacy (i.e., their use approximately doubles the cessation rate among users and their use has shown a high level of economic rewarding). The most important advantage of OTC NRT is availability, as some patients may not be comfortable with the use of prescribed drugs. The introduction of OTC NRT has led to a substantial rise in their use, increasing the proportion of ex-smokers in the population. However, there are a lack of published, cost-benefit analysis data comparing prescription with OTC NRT. Considering the different economic, social and cultural conditions within particular countries, it is difficult to formulate a common optimal economic model for the distribution of NRT. Authentic studies and trials in this field in order to develop the appropriate policies in each particular country, are clearly required.
