Health and health behaviours in adolescence as predictors of education and socioeconomic status in adulthood - a longitudinal study.

Background: The positive association of health with education level and socioeconomic status (SES) is well-established. Two theoretical frameworks have been delineated to understand main mechanisms leading to socioeconomic health inequalities: social causation and health selection but how these work in adolescence is poorly known. We studied if adolescent health and health behaviours predict higher education and higher SES in adulthood and if family background and school performance in adolescence explain these associations.

The role of health literacy in the association between academic performance and substance use.

Background: To address social inequalities in adolescent substance use and consequent disparities in health, it is important to identify the mechanisms of the association between substance use and academic performance. We study the role of health literacy (HL) in the association between academic performance and weekly smoking, monthly alcohol use and cannabis ever-use among adolescents in Europe.

Methods: SILNE-R school survey data, which was collected in 2016-17 with paper-and-pencil-method from Hanover (GE), Amersfoort (NL) and Tampere (FI), were used (N = 5088, age 13-19).

Parents' Participation in School Health Examinations for Their Adolescent Children in Finland.

Engaging parents in school health examinations can promote adolescents' well-being. We examined parents' participation in universal school health examinations in Finland reported by adolescents in school surveys (14 to 16-year-olds,  = 58,232). Further we studied variation between service providers and schools, and student and school-level factors in participation.

Electronic cigarette use among 14- to 17-year-olds in Europe.

Background: Studies comparing adolescent e-cigarette use in different countries are scarce. We study students' e-cigarette and conventional cigarette ever-use, their social correlates and e-liquid use in seven EU countries.

Methods: SILNE-R data (N=12 167, response rate 79.

School tobacco policies and adolescent smoking in six European cities in 2013 and 2016: A school-level longitudinal study.

Assessment of the effectiveness of school tobacco policies (STPs) in reducing adolescent smoking remains inconclusive. Previous studies took insufficient account of different dimensions of STPs, the different views of students and staff, and policy changes over time. This study assessed how a multidimensional STP, as perceived by students and staff, was associated with adolescent smoking over time in six European cities.

Examining retail purchases of cigarettes and nicotine replacement therapy in Finland.

Introduction: Finland's success in achieving the goal of its tobacco endgame largely depends on rectifying deficiencies in the delivery of smoking cessation services. One such weakness, which has not been documented with empirical data, is misuse of nicotine replacement therapy (NRT). This study's objective was to examine purchase patterns of NRT for estimating improper use of the medication.

Nicotine matters in predicting subsequent smoking after e-cigarette experimentation: A longitudinal study among Finnish adolescents.

Background: Several studies indicate an association between e-cigarette use and subsequent smoking among youth. However, most previous studies lack measures of the nicotine content of e-liquid and have not usually measured regular smoking.

Methods: We tested the association between e-cigarette use, with and without nicotine, and subsequent daily use of conventional cigarettes and nicotine e-cigarettes among study population of 3474 students.

Strategies and barriers to achieving the goal of Finland's tobacco endgame.

Objectives: Finland boldly legislated the end of tobacco use in its 2010 Tobacco Act, and subsequently expanded the goal in 2016 to eradicate other nicotine-containing products. This study explored stakeholders' perceptions about the strengths, barriers, solutions and rationale for Finland's comprehensive but conventional strategy to achieve its nicotine-free goal.

Design: Study participants were selected based on expertise in policy or practice of tobacco control (n=32).

Timing of puberty and reserve capacity in adolescence as pathways to educational level in adulthood-a longitudinal study.

Background: Family socioeconomic status (SES) is related to a child's educational success. Intermediate pathways for this relationship, such as through pubertal timing and reserve capacity, occur in adolescence.

Aim: To study whether family SES affects a child's adult education through a psychosocial and behavioural pathway (reserve capacity) and/or a biological pathway (pubertal timing) or only through school achievement in adolescence.

Adolescents notice fewer tobacco displays after implementation of the point-of-sale tobacco display ban in Finland.

Introduction: Finland implemented a point-of-sale (POS) display ban for tobacco products and their trademarks in 2012, and for electronic cigarettes in 2016. In this study we examine whether noticing tobacco products changed among adolescents after the implementation of the display ban and describe the noticing of e-cigarette displays post-implementation.

Methods: Repeated cross-sectional national survey data of 12-to 16-year-olds from years 2011, 2013, 2015 and 2017 were used.

Low schoolwork engagement and schoolwork difficulties predict smoking in adolescence?

Background: Low academic achievement has been associated with smoking but factors behind this association are poorly known. Such factors could include schoolwork disengagement and schoolwork difficulties. To assess the extent to which they contribute to the explanation of how health inequalities emerge, we study in a longitudinal design whether these have an independent effect on smoking or whether their effect is mediated through academic achievement.

A Longitudinal Study of Predictors for Adolescent Electronic Cigarette Experimentation and Comparison with Conventional Smoking.

Little is known of the predictors of electronic cigarette (e-cigarette) use among adolescents, even though the use is increasing. We studied here the predictors for e-cigarette experimentation (tried and tried more than twice) and compared them with predictors for conventional smoking. A baseline school survey was conducted in the Helsinki metropolitan area, Finland, in 2011 for seventh graders (12 to 13-year-olds).

Adolescent reserve capacity, socioeconomic status and school achievement as predictors of mortality in Finland - a longitudinal study.

Background: Despite robust evidence on the inverse relationship between socioeconomic status (SES) and mortality, deviations from expected results have been observed likely due to school achievement and psychosocial resources, termed as "reserve capacity." Since adolescence is a critical period in developing sound psychological and behavioural patterns and adolescent markers of SES were seldom used, we determine if family SES in adolescence predicts later mortality. We also study how reserve capacity (perceived health, health-promoting behaviour and social support) and school achievement modify this relationship and reduce the negative effects of low SES.

Changes in Electronic Cigarette Use from 2013 to 2015 and Reasons for Use among Finnish Adolescents.

Electronic cigarettes are quite a new potential source of nicotine addiction among youth. More research is needed, particularly on e-liquid use and socioeconomic factors as potential determinants. We studied changes from 2013 to 2015 in adolescent e-cigarette awareness and ever-use, types of e-liquids, and determinants in Finland.

Individual and contextual determinants of perceived peer smoking prevalence among adolescents in six European cities.

Background: Young people perceiving a high peer smoking prevalence are more likely to initiate smoking. It is unclear which factors contribute to perceived peer smoking prevalence and if these factors vary according to education. This study aimed to assess the determinants of perceived smoking prevalence and assessed its variation at school and country-level.

Transmission of Smoking across Three Generations in Finland.

The influence of parents' smoking on children's smoking is well known, but few studies have examined the association between grandparents' and grandchildren's smoking. We studied the association between paternal and maternal grandparents' smoking and their grandchildren's tobacco use and assessed whether parents' smoking is a mediator in this process. Data were obtained from a national survey of 12-18-year-old Finns in 2013 (N = 3535, response rate 38%).

School smoking policies and educational inequalities in smoking behaviour of adolescents aged 14-17 years in Europe.

Background: Studies on the effects of school smoking policies are inconclusive and there is no research on whether the effects of school policies vary by educational level. We examined the association between school smoking policies and smoking behaviour among adolescents aged 14-17 years in Europe and assessed educational inequalities in these associations.

Methods: Data on 10,325 adolescents from 50 schools in six European cities were obtained from the 2013 SILNE survey.

Feasibility of using a multilingual web survey in studying the health of ethnic minority youth.

Background: Monolingual Web survey is a common tool for studying adolescent health. However, national languages may cause difficulties for some immigrant-origin youths, which lower their participation rate. In national surveys, the number of ethnic minority groups is often too small to assess their well-being.

Time trends in single versus concomitant neck and back pain in Finnish adolescents: results from national cross-sectional surveys from 1991 to 2011.

Background: Previous studies, in late 20th century, suggest an increase in the prevalence of neck pain and low back pain among children and adolescents, when neck and low back pain were studied separately. This study investigated time trends in adolescent spinal pain between 1991 and 2011 by classifying pain into the following three classes: neck pain alone, low back pain alone, and concomitant neck and low back pain.

Methods: Representative samples of 12 to 18-year-old Finns were sent a questionnaire in 1991, 1999, 2001, 2003, 2005, 2007, 2009 and 2011.

Awareness and determinants of electronic cigarette use among Finnish adolescents in 2013: a population-based study.

Background: A wide range of electronic cigarettes (e-cigarettes) are now on the market. We studied e-cigarette awareness and use, determinants and sources of e-cigarettes, the e-liquids used in them and exposure to e-cigarette advertisements among adolescents in Finland. Among smokers, we studied the association of e-cigarette use and interest in smoking cessation.

Persistence of socioeconomic differences in adolescents' environmental tobacco smoke exposure in Finland: 1991-2009.

Aims: Socioeconomic differences in children's exposure to environmental tobacco smoke (ETS) in favour of those with higher positions are known, but research is scarce on whether differences have persisted when smoking restrictions have been tightened. We examined socioeconomic differences in adolescents' ETS exposure from 1991 to 2009 in Finland where the tobacco law has gradually restricted smoking of population.

Methods: National cross-sectional surveys (1991-2009) in 12-18-year-olds (N=72,726, response rate 77-56%).

From childhood socio-economic position to adult educational level - do health behaviours in adolescence matter? A longitudinal study.

Background: Our interest was in how health behaviours in early and late adolescence are related to educational level in adulthood. The main focus was in the interplay between school career and health behaviours in adolescence. Our conceptual model included school career and health-compromising (HCB) and health-enhancing (HEB) behaviours as well as family background.

Occurrence of violence among 12-18-year-old adolescents in 1999 and 2009 in Finland.

We examined whether the occurrence of violence changed among Finnish adolescents between 1999 and 2009. The study was based on the nationwide Adolescent Health and Lifestyle Survey from samples of 12- to 18-year-olds. The number of respondents was 8136 in 1999 and 5516 in 2009.

Cyberbullying among Finnish adolescents--a population-based study.

Background: Cyberbullying, threatening or harassing another via the internet or mobile phones, does not cause physically harm and thus the consequences are less visible. Little research has been performed on the occurrence of cyberbullying among adolescents or the perception of its seriousness. Only a few population-based studies have been published, none of which included research on the witnessing of cyberbullying.

Musculoskeletal symptoms and computer use among Finnish adolescents--pain intensity and inconvenience to everyday life: a cross-sectional study.

Background: Musculoskeletal symptoms among adolescents are related to the time spent using a computer, but little is known about the seriousness of the symptoms or how much they affect everyday life. The purpose of the present study was to examine the intensity of musculoskeletal pain and level of inconvenience to everyday life, in relation to time spent using a computer.

Methods: In a survey, 436 school children (12 to 13 and 15 to 16 years of age), answered a questionnaire on musculoskeletal and computer-associated musculoskeletal symptoms in neck-shoulder, low back, head, eyes, hands, and fingers or wrists.
