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. METHODS: Surveys on health and health behaviours were sent to representative samples of 12-18-year-old Finns in 1981-1997 every second year (response rate 77.8%, N = 55,682). The survey data were linked with the respondents' and their parents' socioeconomic data from the Finnish national registries. Both latent variables, namely, health (perceived health, health complaints, chronic disease), health-compromising behaviours (smoking status, drunkenness frequency), and family background (parents' occupation-based SES, education, family type) and variables directly measuring health-enhancing behaviours (toothbrushing, physical activity) and school performance were used to predict higher education and higher occupation-based SES at age 34. Logistic regression analysis and structural equation models (SEM) were used. RESULTS: In logistic regression analyses, good health, health-enhancing behaviours, and lack of health-compromising behaviours were related to higher education and SES, also after controlling for family background and school performance. In the SEM analyses, good health, health-enhancing behaviours, and lack of health-compromising behaviours directly predicted higher SES and higher education, although the standardised coefficients were low (from 0.034 to 0.12). In all models, health, lack of health-compromising behaviours, and health-enhancing behaviours predicted school performance, which in turn, predicted the outcomes, suggesting indirect routes to these. Good socioeconomic prospects in terms of family background predicted good health, healthy behaviours, and good school performance in adolescence and higher SES and higher education in adulthood. CONCLUSION: Health and health behaviours in adolescence predicted education and SES in adulthood. Even though the relationships were modest, they support the health selection hypotheses and emphasise the importance of adolescence for health inequalities during the life-course. Health and health behaviours were strongly associated with school performance and family background which together modified the paths from health and health behaviours to the outcomes.

Towards Tobacco-Free Generation: implementation of preventive tobacco policies in the Nordic countries.

AIMS: Europe's Beating Cancer Plan set a goal of creating a Tobacco-Free Generation in Europe by 2040. Prevention is important for achieving this goal. We compare the Nordic countries' preventive tobacco policies, discuss the possible determinants for similarities and differences in policy implementation, and provide strategies for strengthening tobacco prevention. METHODS: We used the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) to identify the key policies for this narrative review. We focused on Articles 6, 8, 9, 11, 13 and 16 of the WHO FCTC, and assessed the status of the required (core) and recommended (advanced) policies and their application to novel tobacco and nicotine products. Information on the implementation of strategies, acts and regulations were searched from global and national tobacco control databases, websites and scientific articles via PubMed and MEDLINE. RESULTS: The WHO FCTC and European regulations have ensured that the core policies are mostly in place, but also contributed to the shared deficiencies that are seen especially in the regulations on smokeless tobacco and novel products. Strong national tobacco control actors have facilitated countries to implement some advanced policies - even as the first countries in the world: point-of-sale display bans (Iceland), outdoor smoking bans (Sweden), flavour bans on electronic cigarettes (Finland), plain packaging (Norway), and plain packaging on electronic cigarettes (Denmark). CONCLUSIONS: Collaboration and participation in reinforcing the European regulations, resources for national networking between tobacco control actors, and national regulations to provide protection from the tobacco industry's interference are needed to strengthen comprehensive implementation of tobacco policies in the Nordic countries.

School and class closures and adolescent mental health during the second and later waves of the COVID-19 pandemic in Finland: a repeated cross-sectional study.

BACKGROUND: Since the start of the COVID-19 pandemic, several studies have shown deterioration of adolescents' mental health when comparing periods before and after the start of the pandemic when there were national school closures. Less is known of the following waves with more variation in school closures and their duration. We study here, if variation in school or class closures was related to adolescents' mental health, if the duration mattered, and if the relationships were gender sensitive. METHODS: All comprehensive schools in Finland were invited to participate. Students (grades 7-9, age 13-16 years) answered digitally in November-December 2020 (n = 41,041) and April-May 2021 (n = 28,501). The responses were given anonymously. Mental health was measured by daily health complaints and moderate/severe anxiety (GAD-7, only in 2021). School and class closures were combined to a variable (yes/no). The duration of a closure was analysed in weeks. Logistic regression analysis was used. RESULTS: In 2020, 14% of pupils reported a school closure and 33% in 2021. The gender-adjusted odds for daily health complaints were higher among those with the school or class closure compared to those without (OR = 1.2 (1.1-1.3) in 2020; OR = 1.3 (1.2-1.3) in 2021). For anxiety, the corresponding OR was 1.3 (1.2-1.4). Girls had higher odds for both measures than boys and the non-binary gender had the highest. A one-week increase in the duration of closure had a small effect on daily health complaints OR = 1.05 (1.02-1.09) in 2020; OR = 1.05 (1.02-1.08) in 2021) and anxiety OR = 1.05 (1.01-1.08). Gender differences in the associations of the school or class closure with mental health were negligible. CONCLUSIONS: A specific negative influence of school or class closures on adolescents' mental health was seen when comparing those who had school/class closure and those who did not during the further waves of the pandemic. The duration of closure had a small effect, too. The non-binary gender had lowest mental health, but the influence of school closure on mental health was mainly similar between the genders. School closures are one of the factors in adolescents' mental health, but not the only one.

Online health information-seeking behaviour and mental well-being among Finnish higher education students during COVID-19.

Online health information-seeking behaviour has increased since the World Health Organization declared COVID-19 a global pandemic in March 2020. This study examined whether health-related information on COVID-19 searched on the internet was associated with mental well-being among higher education students. A cross-sectional internet survey was conducted among 18- to 34-year-old students in Finland (N = 2976; mean age 24.61 years and median 24) in the spring of 2020. The data were analysed using descriptive statistics, Pearson's chi-square tests, Kruskal-Wallis nonparametric H tests, and a two-way ANOVA. The results indicated that most students (86% of females, 82% of males) used the internet to search for information on COVID-19. Students' self-perceived abilities to determine the relevance of online information on COVID-19 were associated with mental well-being.

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). Health Literacy for School-aged Children instrument was used to assess students' HL. Logistic regression analyzed the association of substance use with academic performance and HL, separately and in the same model. Linear and multinomial logistic regression analyzed the association between academic performance and HL. RESULTS: Poor academic performance compared with high was associated with smoking [odds ratio (OR) 3.94, 95% confidence interval (CI) 2.83-5.49], alcohol use (OR: 2.94, 95% CI: 2.34-3.68) and cannabis use (OR: 2.56, 95% CI: 1.89-3.48). Poor HL was also associated with each substance use (with ORs of 2.32, 1.85 and 1.29). HL was positively associated with academic performance (ß = 1.04, 95% CI: 0.89-1.20). The associations between academic performance and substance use were only slightly attenuated after controlling for HL. CONCLUSIONS: Academic performance and HL were both determinants of substance use, confirming their role in tackling the disparities in substance use. However, HL did not demonstrably mediate the association between academic performance and substance use. A wider set of factors needs to be tackled to address emerging social inequalities in adolescent substance use.

The association between migration and smoke-free families: how do migrants from different world regions compare?

BACKGROUND: Studies on adolescent secondhand smoke exposure within the family often dichotomously operationalize migration background without paying attention to social and cultural diversity within migrant populations. As a result, little is known about variation within migrant groups in smoke-free family environments (SFFEs). This study analyses the association between SFFEs and parental migration from different world regions. METHODS: Data from 14- to 16-year-old adolescents (N = 17 144) on SFFEs and parental migration were obtained from cross-sectional repeated SILNE-R surveys. A multivariable multinomial regression was applied, presenting relative risks (RRs) with 95% confidence intervals (CIs) for maternal or paternal tobacco smoking and home smoking bans. Variation in migration background was measured according to parental sex and place of birth. RESULTS: Approximately 18% of adolescents are exposed to maternal smoking, and 25% are exposed to paternal smoking. Almost half of the respondents do not live in SFFEs but are subject to permissive (5%) or partial (39%) smoking bans at home. We found that adolescents of Eastern European descent are at a higher risk of being exposed to both paternal and maternal smoking. A sex difference in parental smoking was found among Arabic/Islamic migrants, where mothers are less likely to be smokers. Maternal and paternal African origins are associated with prohibitive smoking bans at home. Eastern European mothers show higher odds of permissiveness and freely allowing smoking at home. CONCLUSION: Notable within-differences according to parental sex and place of birth were found for SFFEs and should be taken into account when implementing equity-sensitive tobacco prevention programs.

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 79.4%) of 14-17-year-olds from Amersfoort (NL), Coimbra (PT), Dublin (IR), Hanover (GE), Latina (IT), Namur (BE) and Tampere (FI) were used. E-cigarette and conventional cigarette ever-use, dual-use, type of e-liquid and social correlates were measured with a school survey and analyzed with cross-tabulations and multinomial logistic regression. RESULTS: About 34% had tried e-cigarettes, but the variation was large between the cities (Latina 50%; Hanover 23%). Of e-cigarette ever-users, 37% had used nicotine e-liquid, 43% exclusively non-nicotine liquid and 20% did not know the content. Nicotine e-liquid was more prevalent among monthly e-cigarette users and weekly smoking e-cigarette users. The social correlates were mainly the same for exclusive e-cigarette ever-use, exclusive conventional cigarette ever-use and dual-use. Boys had greater odds for exclusive e-cigarette and dual-use compared to girls. Of social correlates, low academic achievement and parental smoking were positively associated with all categories of use, but parental education and immigrant background were not. The strongest association was found between peer smoking (most/all best friends smoke) and dual-use (OR 34.29). CONCLUSIONS: Students' e-cigarette ever-use varies greatly between EU countries. E-cigarettes seem not to be a substitute for conventional cigarettes but more a complementary product. Tobacco control policies might also prevent e-cigarette use but specific regulations on e-cigarettes are needed to prevent nicotine addiction originating from them.

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, N = 58,232). Further we studied variation between service providers and schools, and student and school-level factors in participation. National data were analyzed using multilevel logistic regression models. Less than half of the adolescents reported parents' participation. The variation between service providers and schools was large. Non-participation was associated with mother's low education, students' immigrant background, daily health complaints, heavy drinking, and discussion difficulties with parents. Boys and those who did not live with both mother and father had a higher risk for parents' non-participation. Adolescents with a long-term illness or being bullied reported participation more often. Inviting parents and the school health nurse resource were not associated with participation. Our results raise the question of barriers to participation in health examinations.

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. The SILNE and SILNE-R surveys were conducted among students (n = 18,502) and staff (n = 438) in 38 schools in 2013 and 2016. Three dimensions (comprehensiveness, enforcement, and communication) were assessed and we calculated total STP scores. Multilevel logistic regressions estimated associations of STPs with adolescent smoking on and just outside school premises and with weekly smoking. Further analyses estimated associations between 2013 and 2016 STP changes and smoking outcomes in 2016, controlling for STP and smoking prevalence in 2013. On average, there were few increases in STP scores over time. Greater STP enforcement, as perceived by students, was associated with lower odds of weekly smoking (OR:0.93, 95%CI:0.89-0.97) and of smoking on school premises (OR:0.80, 95%CI:0.72-0.90). Higher total STP scores were associated with lower odds of smoking on school premises (OR:0.76, 95%CI:0.67-0.86), but not of smoking just outside premises or smoking weekly. Greater increases in STP scores over time were associated with lower odds of smoking on school premises in 2016 (OR:0.65, 95%CI:0.47-0.89). Well-enforced STPs may help reduce adolescent smoking at school. Schools should be supported in adopting comprehensive policies that also extend to the surroundings of their premises.

Economic Evaluation of Five Tobacco Control Policies Across Seven European Countries.

INTRODUCTION: Economic evaluations of tobacco control policies targeting adolescents are scarce. Few take into account real-world, large-scale implementation costs; few compare cost-effectiveness of different policies across different countries. We assessed the cost-effectiveness of five tobacco control policies (nonschool bans, including bans on sales to minors, bans on smoking in public places, bans on advertising at points-of-sale, school smoke-free bans, and school education programs), implemented in 2016 in Finland, Ireland, the Netherlands, Belgium, Germany, Italy, and Portugal. METHODS: Cost-effectiveness estimates were calculated per country and per policy, from the State perspective. Costs were collected by combining quantitative questionnaires with semi-structured interviews on how policies were implemented in each setting, in real practice. Short-term effectiveness was based on the literature, and long-term effectiveness was modeled using the DYNAMO-HIA tool. Discount rates of 3.5% were used for costs and effectiveness. Sensitivity analyses considered 1%-50% short-term effectiveness estimates, highest cost estimates, and undiscounted effectiveness. FINDINGS: Nonschool bans cost up to €253.23 per healthy life year, school smoking bans up to €91.87 per healthy life year, and school education programs up to €481.35 per healthy life year. Cost-effectiveness depended on the costs of implementation, short-term effectiveness, initial smoking rates, dimension of the target population, and weight of smoking in overall mortality and morbidity. CONCLUSIONS: All five policies were highly cost-effective in all countries according to the World Health Organization thresholds for public health interventions. Cost-effectiveness was preserved even when using the highest costs and most conservative effectiveness estimates. IMPLICATIONS: Economic evaluations using real-world data on tobacco control policies implemented at a large scale are scarce, especially considering nonschool bans targeting adolescents. We assessed the cost-effectiveness of five tobacco control policies implemented in 2016 in Finland, Ireland, the Netherlands, Belgium, Germany, Italy, and Portugal. This study shows that all five policies were highly cost-effective considering the World Health Organization threshold, even when considering the highest costs and most conservative effectiveness estimates.

The Association Between Smoke-Free School Policies and Adolescents' Perceived Antismoking Norms: Moderation by School Connectedness.

INTRODUCTION: Many European schools implement smoke-free school policies (SFSPs). SFSPs may decrease adolescent smoking by causing adolescents to perceive stronger antismoking norms, yet there exists no quantitative evidence that indicates for which norms and for whom such effects may occur. This study therefore assessed to what extent adolescents' perceived antismoking norms among best friends, teachers, and society at large were associated with SFSPs, and whether these associations were moderated by adolescents' level of school connectedness. AIMS AND METHODS: Survey data were collected in 2016/2017 on 10,653 adolescents aged 14-16 years old and 315 staff members in 55 schools from seven European cities. Associations of adolescent-perceived SFSPs and staff-reported SFSPs with best friend, teacher, and societal antismoking norms were estimated in multilevel logistic regression models, adjusted for demographics and school-level smoking prevalence. We tested for interaction between school connectedness and SFSPs. RESULTS: Adolescent-perceived SFSPs were positively associated with antismoking norms by teachers (odds ratio [OR]: 1.46, 95% confidence interval [CI]: 1.15-1.85), were negatively associated with antismoking norms by best friends (OR: 0.81, 95% CI: 0.67-0.99), but were not significantly associated with antismoking norms by society at large (OR: 0.87, 95% CI: 0.74-1.02). All interaction tests between adolescent-perceived SFSPs and school connectedness were nonsignificant. Staff-reported SFSPs were not associated with any norm and showed no significant interaction with school connectedness. CONCLUSIONS: We found that SFSPs are associated with adolescents' perception of more antismoking norms by teachers, but less antismoking norms by best friends, irrespective of adolescents' level of school connectedness. IMPLICATIONS: Smoke-free school policies, just as many other tobacco control policies, are assumed to foster adolescents' perception of antismoking norms. Still, current evidence does not demonstrate which antismoking norms may be influenced by SFSPs and whether this influence is equal for adolescents with different levels of school connectedness. This study suggests that SFSPs foster adolescents' perception of antismoking norms by teachers, but may concurrently lead to the perception of less antismoking norms by best friends, irrespective of adolescents' school connectedness. SFSPs may therefore need to be complemented with interventions that target antismoking norms in adolescent peer groups.

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). Semi-structured interviews, conducted in 2017 and 2018, covered topics ranging from consensus among stakeholders to Finland's ranking on the 2016 Tobacco Control Scale. The framework method was chosen for analysing interview transcripts. RESULTS: A perceived strength of Tobacco-Free Finland 2030 was the consensus and cooperation among members of the tobacco control community. The objective of becoming a nicotine- versus smoke-free society had almost unanimous support, challenged by a small minority who argued for greater discussion of harm reduction approaches. The need for maintaining legitimacy and historical successes in tobacco control were reasons for using a conventional strategy. Barriers to achieving the endgame goal included insufficient funding and over-reliance on non-governmental organisations, political/legal constraints, impact of institutional practices on tobacco disparities, ambivalence about the role of mass media and lack of prioritising smoking cessation. CONCLUSIONS: Stakeholders' broad confidence in reaching the goal of Finland's tobacco endgame suggests that future policy initiatives will reflect the current, conventional strategy. If the Finnish government chooses to continue this approach, then it should designate separate funds for Tobacco-Free Finland 2030 and implement structural changes that will facilitate tobacco control initiatives.

Social determinants of adolescent smoking over three generations.

Aim: We studied how multigenerational socioeconomic circumstances influence adolescents' smoking. Previous studies have shown that low academic achievement as well as parents' low socioeconomic circumstances are associated with adolescents' smoking, but there are few studies on grandparents' influence on their grandchildren's smoking. For the chain of three generations, we hypothesised that high socioeconomic circumstances of both parents and grandparents decrease the probability of smoking and adolescents' own education and circumstances contribute to this association. We further investigated the role of intergenerational social mobility. Method: Survey data from 1979 to 1997 on 12- to 18-year-old Finns (n=54,487) were linked with 1970-2009 registry-based data of their grandparents, parents and themselves. Socioeconomic circumstances among parents and grandparents were measured by socioeconomic status, education and material resources and among adolescents by academic achievement, educational orientation, family structure and parental smoking. Logistic regression analysis was used to study the associations. Results: Associations of adolescent smoking with grandparental socioeconomic circumstances were weak and mediated through parental circumstances. Parental smoking and divorce and living in a non-intact family increased smoking. Adolescents' low academic achievement and orientation to low education level were the most important predictors of smoking. Upward intergenerational social mobility between fathers and children decreased the risk of smoking, whereas downward mobility increased it. Conclusions: The influence of grandparents' low socioeconomic circumstances on grandchildren's smoking is mediated through parents' socioeconomic circumstances. Low academic achievement in adolescence is a strong predictor of smoking and adolescents orient towards the group of their future education level, not that of their parents.

Late start of upper secondary education and health-compromising behaviours among Finnish adolescents-a follow-up study.

BACKGROUND: The Finnish government has emphasized the need to expedite educational transitions. We study if a late start of upper secondary education is related to health-related selection, namely health-compromising behaviours in adolescence. METHODS: A large cohort of adolescents from the seventh (12-13 years) and ninth (15-16 years) grades answered online classroom surveys (total n = 10 873). They were followed to the start of upper secondary education, obtained from the Joint Application Registry. We compared those who continued studies directly from the ninth grade with later starters. We measured late bedtime, breakfast not every school day, tooth brushing less than twice-a-day, monthly alcohol consumption, weekly smoking, daily energy drinks, physical activity <6 days/week and excessive screen time. Multilevel logistic regressions and latent class analyses were conducted. RESULTS: In gender and school adjusted models in the seventh grade, all behaviours except physical activity predicted the late start. The strongest predictor was smoking, OR = 2.96 (CI = 2.25-3.89). In the ninth grade, smoking, breakfast, tooth brushing and energy drinks, OR = 1.80, (CI = 1.36-2.39, strongest), were predictive. After controlling for sociodemographic background and academic achievement, associations for alcohol and screen time became non-significant in the seventh grade. In the ninth grade, only screen time remained significant, OR = 1.33 (CI = 1.04-1.71). Health-compromising behaviours formed clusters. Belonging to the unhealthy cluster predicted the late start in both grades, in adjusted models only in the seventh grade. CONCLUSIONS: Students with health-compromising behaviours are less likely to start upper secondary education directly after the compulsory education. This may increase the risk for fragmentary educational trajectories and work careers.

Cost of youth tobacco-control policies in seven European countries.

BACKGROUND: Tobacco-control policies have been suggested to reduce smoking among adolescents. However, there is limited evidence on the real-world costs of implementation in different settings. In this study, we aimed at estimating the costs of school smoking bans, school prevention programmes and non-school bans (smoking bans in non-educational public settings, bans on sales to minors and bans on point-of-sale advertising), implemented in Finland, Ireland, the Netherlands, Belgium, Germany, Italy and Portugal, for 2016. METHODS: We retrospectively collected costs related to the inspection, monitoring and sanctioning activities related to bans and educational activities related to smoking prevention programmes. We used an 'ingredients-based' approach, identifying each resource used, quantity and unit value for one full year, under the state perspective. Costs were measured at national, regional, local and school-level and were informed by data on how these activities were performed in reality. RESULTS: Purchasing power parities adjusted-costs varied between €0.02 and €0.74 (average €0.24) per person (pp) for bans implemented outside schools. Mean costs of school smoking bans ranged from €3.31 to €34.76 (average €20.60), and mean costs of school educational programmes from €0.75 to €4.65 (average €2.92). CONCLUSIONS: It is feasible to estimate costs of health policies as implemented in different settings. Costs of the tobacco control policies evaluated here depend mainly on the number of person-hours allocated to their implementation, and on the scale of intervention. Non-school bans presented the lowest costs, and the implementation of all policies cost up to €36 pp for 1 year.

Adolescent Gambling, Gambling Expenditure and Gambling-Related Harms in Finland, 2011-2017.

Existing literature on recent trends in adolescent gambling is scarce. The rapidly changing landscape of gambling, together with the generally applied legal age limits, calls for the continuous monitoring of gambling also among the adolescent population. In Finland, the legal gambling age is 18. We examined changes in adolescents' gambling, gambling expenditure and gambling-related harms from 2011 to 2017. Comparable cross-sectional biennial survey data were collected in 2011, 2013, 2015 and 2017 among 12-18-year-olds (N = 18,857). The main measures were self-reported six-month gambling, average weekly gambling expenditure (€) and harms due to gambling. Data were analyzed using cross-tabulations, χ2-tests and linear regression analysis. A significant decline in gambling among minors (aged 12-16-year-olds) was found (ß = - 0.253), while no significant changes were observed among 18-year-olds (who are not targeted by the law). The mean gambling expenditure also declined from 2011 to 2017. Adolescent gamblers experienced significantly less (p = .003) gambling-related harms in 2017 (7.4%) compared to 2011 (13.5%). Adolescent gambling and its related negative consequences have become less prevalent in Finland between 2011 and 2017. Further monitoring is necessary to ascertain whether the positive direction will continue. Also, empirical analyses providing evidence of reasons for the observed trend are warranted.

Bidirectional Relationship of Sleep with Emotional and Behavioral Difficulties: A Five-year Follow-up of Finnish Adolescents.

The long-term effects of sleep on adolescent psychosocial well-being are mostly unknown, although insufficient sleep has been associated with emotional and behavioral difficulties in cross-sectional studies. With a five-year follow-up of Finnish adolescents (Time 1: n = 8834; Mean age = 13 years, 51.1% female, Time 2: n = 5315, Mean age = 15 years, 51.6% female, Time 3: n = 3712; Mean age = 17 years; 50.2% female), the purpose of this longitudinal study was to investigate the relations between self-reported sleep duration, sleep problems, and emotional and behavioral difficulties during adolescence. Emotional and behavioral difficulties were assessed using The Strengths and Difficulties Questionnaire (SDQ) measuring emotional symptoms, conduct problems, hyperactivity, peer problems and total difficulties. Sleep duration was calculated by counting the hours between self-reported bedtime and wake-up time. Sleep problems were assessed with a single question about the general sleep problems. According to the cross-lagged models for sleep and emotional and behavioral difficulties, the findings of this study indicate a developmental process during adolescence where, firstly, short sleep duration is a stronger predictor for current and prospective emotional and behavioral difficulties than vice versa. Secondly, increased emotional and behavioral difficulties expose adolescents to current and later sleep problems more strongly than reverse. Thus, the results show that short sleep duration predisposed to emotional and behavioral difficulties across adolescence, which then led to more prospective sleep problems. These findings suggest a developmental process where sleep and emotional and behavioral difficulties are intertwined in shaping adolescents' health.

Health and educational aspirations in adolescence: a longitudinal study in Finland.

BACKGROUND: The health selection hypothesis suggests that poor health leads to low educational attainment during the life course. Adolescence is an important period as poor health might prevent students from making the best educational choices. We test if health in adolescence is associated with educational aspirations and whether these associations persist over and above sociodemographic background and academic achievement. METHODS: Using classroom surveys, a cohort of students (n = 5.614) from the Helsinki Metropolitan Region was followed from the 7th (12-13 years,) up to the 9th grade (15-16 years) when the choice between the academic and the vocational track is made in Finland. Health factors (Strengths and Difficulties Questionnaire (SDQ), self-rated health, daily health complaints, and long-term illness and medicine prescribed) and sociodemographic background were self-reported by the students. Students' educational aspirations (applying for academic versus vocational track, or both) and their academic achievement were obtained from the Joint Application Registry held by the Finnish National Agency for Education. We conducted multilevel multinomial logistic regression analyses, taking into account that students are clustered within schools. RESULTS: All studied health factors were associated with adolescents' educational aspirations. For the SDQ, daily health complaints, and self-rated health these associations persisted over and above sociodemographic background and academic achievement. Students with better health in adolescence were more likely to apply for the academic track, and those who were less healthy were more likely to apply for the vocational track. The health in the group of those students who had applied for both educational tracks was in between. Inconsistent results were observed for long-term illness. We also found robust associations between educational aspirations and worsening health from grade 7 to grade 9. CONCLUSIONS: Our findings show that selection by health factors to different educational trajectories takes place at early teenage much before adolescents choose their educational track, thus supporting the health selection hypothesis in the creation of socioeconomic health inequalities. Our findings also show the importance of adolescence in this process. More studies are needed to reveal which measures would be effective in helping students with poor health to achieve their full educational potential.

Health and socioeconomic circumstances over three generations as predictors of youth unemployment trajectories.

BACKGROUND: Youth unemployment is a critical life event, which may trigger other labour market-related disadvantages and detrimental health implications. To better understand the processes causing unemployment, we study how socioeconomic circumstances of successive generations and familial and health factors in adolescence predict youth unemployment trajectories between ages 16 and 28 in Finland from 2000 to 2009. METHODS: We used survey data from 1979 to 1997 on 12- to 18-year-old Finns (n = 43 238) linked with 1970-2009 registry-based data of their grandparents, parents and themselves. Growth mixture modelling and multivariate logistic regression analyses were used. RESULTS: Three latent youth unemployment trajectories emerged; low (46%), decreasing (38%) and high (16%) risk groups. Of adolescent factors, low school achievement was the most important predictor of youth unemployment followed by smoking, stress symptoms and poor self-rated health. Grandparents' education predicted their grandchildren's unemployment but the effects of other grandparental socioeconomic circumstances mediated through parents' socioeconomic status (SES). Parents' low SES and education, and long-term unemployment increased the risk of the child's unemployment. Youth unemployment was related to low education at the age of 29. CONCLUSION: Grandparents' education, family socioeconomic circumstances and adolescents' health and school achievement predict the developmental trajectory of youth unemployment. Youth unemployment is also related to low education in early adulthood. Our findings suggest that the health selection of unemployment works already in adolescence.

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. Methods: Longitudinal data were collected in the Helsinki metropolitan area, Finland in 2011 and 2014. Participants were seventh-graders (12 - 13 years, N=9497). In the follow-up, 6534 students reported their smoking status in the ninth grade (15 - 16 years). Smoking, schoolwork behavioural engagement, i.e. participation in academic activities, and disengagement, schoolwork difficulties and cognitive competence were self-reported by adolescents. Academic achievement was obtained from the Finnish national application register on upper secondary education. A mediation analysis was executed with bootstrapped confidence intervals. Results: Higher schoolwork behavioural engagement and cognitive competence in the seventh grade predicted that adolescents were more likely not to smoke in the ninth grade (all P<0.001) while higher schoolwork disengagement and schoolwork difficulties predicted adolescents' smoking (all P<0.001). The effects were mediated through academic achievement. Conclusions: Students' behavioural disengagement with schoolwork and schoolwork difficulties are risks for smoking initiation. Their effect is mediated through poor school achievement. As smoking often continues in adulthood and poor school performance typically leads to lower education, schoolwork disengagement and difficulties in adolescence constitute potential pathways to inequalities in health.
