Using emulated clinical trials to investigate the risk of being diagnosed with psychiatric ill health following the cancer diagnosis of a sibling.

BACKGROUND: The sibling bond is often the longest relationship in an individual's life, spanning both good and bad times. Focusing on the latter, we investigated whether a cancer diagnosis in one adult sibling is predictive of psychiatric illness in the other, and if any such effect differs according the 'sociodemographic closeness' between the siblings in terms of sex, age, education, marital status and residence. METHODS: We used hospital records to identify psychiatric diagnoses (2005-2019) in a Swedish total-population cohort born in 1953, and cancer diagnoses (2005-2017) in their full siblings. By means of emulated clinical trials, the cohort member's risk of a diagnosis within two years following a first exposure (or non-exposure) to a sibling's cancer was analyzed through Cox regression. RESULTS: Exposed cohort members had a higher risk of psychiatric diagnosis than unexposed (HR = 1.15; CI: 1.08-1.23), with men displaying a higher risk (1.19; CI: 1.09-1.31) than women (HR = 1.11; CI: 1.01-1.22). Sub-analyses of the exposed group showed that women with a cancer-stricken sister had a higher risk of adverse psychiatric outcomes (HR = 1.31; CI: 1.07-1.61) than women with a cancer-stricken brother. Furthermore, unmarried cohort members ran a higher risk, both when the cancer-stricken sibling was married (HR = 2.03; CI: 1.67-2.46) and unmarried (HR = 2.61; CI: 2.16-3.15), than in cases where both siblings were married. No corresponding difference were detected for 'closeness' in age, education and residence. CONCLUSIONS: In line with theories of linked lives, our findings suggest that negative events in one sibling's life tend to 'spill over' on the other sibling's wellbeing, at least during the 15-year-long period leading up to retirement age.

Perceived problematic alcohol use in the family and adolescents' stress-related complaints: examining the buffering role of the school's degree of student focus as rated by its teachers.

BACKGROUND: A non-negligible proportion of children grow up with problematic alcohol use in the family. Problematic familial drinking can be regarded as a stressor, and prior studies have consistently reported poorer mental health among adolescents who are exposed. However, it is also of relevance to identify modifiable protective factors which may buffer against stress-related ill-health in this group of adolescents. One context where such factors may be present is the school. The aim of this study is to examine the relationship between perceived problematic familial alcohol use and students' stress-related complaints, and specifically to explore if the school's degree of student focus can buffer against any such negative health consequences of problem drinking at home. METHODS: Data were drawn from four separate surveys, the Stockholm School Survey (SSS) and the Stockholm Teacher Survey (STS) conducted in 2014 and 2016 among 7,944 students (~ 15-16 years) and 2,024 teachers in 147 Stockholm senior-level school units. Perceived problematic familial alcohol use was measured by one item in the SSS. Stress-related complaints were captured by co-occurring somatic complaints and psychological distress, and reported by students in the SSS. The school's student focus was measured by an index based on teachers' ratings of four items in the STS. A set of covariates at the student and the school level were also included. Two-level binary logistic and linear regression models were performed. RESULTS: Perceived problematic familial alcohol use was linked with an increased likelihood of reporting co-occurring somatic complaints as well as psychological distress. Cross-level interactions revealed that the association between perceived problematic familial alcohol use and co-occurring somatic complaints was weaker among students attending schools with stronger teacher-rated student focus. Regarding psychological distress, the association was weaker for students attending schools with intermediate or strong teacher-rated student focus, compared with those attending schools with weaker teacher-rated student focus. CONCLUSIONS: The findings provide support for the assumption that favourable conditions in schools can buffer against negative health consequences of problematic conditions in the family, thus serving a compensatory role.

School collective efficacy and gambling: A multilevel study of 11th grade students in Stockholm.

The aim of the present study was to investigate variations between schools when it comes to gambling and risk gambling, and, in particular, to analyse the links between school collective efficacy and student gambling and risk gambling. The data consists of official register information on schools as well as survey data collected in 2016 among 1,061 teachers and 5,191 students in 46 Stockholm upper secondary schools. School collective efficacy was operationalized on the basis of teacher responses, which were aggregated to the school level. Gambling and risk gambling were based on students' self-reports. Two-level binary logistic regression analyses were performed. The results show that there is between-school variation in gambling and in all the study's indicators of risk gambling. Both gambling and risk gambling were more commonly reported by students attending schools with weak collective efficacy, even when adjusting for student- and school-level sociodemographic characteristics. The findings suggest that conditions at school may counteract students' engagement in gambling and risk gambling.

Is there a peer status gradient in mortality? Findings from a Swedish cohort born in 1953 and followed to age 67.

BACKGROUND: Similar to having a less advantaged socioeconomic position, children in lower peer status positions typically experience a situation characterized by less power, influence and command over resources, followed by worse health outcomes. The aim of this study was to examine whether peer status position is further associated with increased risks for premature all-cause mortality. METHODS: Data were drawn from a 1953 cohort born in Stockholm, Sweden. Peer status positions were established through survey data on peer nominations within the school class at age 13, whereas national registers were used to identify all-cause mortality across ages 14-67. Differences in hazard rates and median survival time, according to peer status position, were estimated with Cox regression and Laplace regression, respectively. RESULTS: Although differences in hazard rates were not large, they were consistent and clear, also after taking childhood socioeconomic status into account. Regarding median survival time, the number of years lost increased gradually as peer status decreased, with a difference of almost 6 years when comparing individuals in the lowest and highest positions. CONCLUSIONS: Children's positions in the peer status hierarchy play a role for their chances of health and survival, pointing to the relevance of addressing opportunities for positive peer interaction and mitigating any adverse consequences that may stem from negative experiences within the peer context.

Pathways from Childhood Economic Conditions to Adult Mortality in a 1953 Stockholm Cohort: The Intermediate Role of Personal Attributes and Socioeconomic Career.

Although both childhood and adult economic conditions have been found to be associated with mortality, independently or in combination with each other, less is known about the role of intermediate factors between these two life stages. This study explores the pathways between childhood economic conditions and adult mortality by taking personal attributes as well as adult socioeconomic career into consideration. Further, we investigate the role of intergenerational income mobility for adult mortality. We used data from a prospective cohort study of individuals that were born in 1953 and residing in Stockholm, Sweden, in 1963 who were followed for mortality between 2002 and 2021 (n = 11,325). We fit Cox proportional hazards models to assess the association of parental income, cognitive ability, social skills, educational attainment, occupational status, and adult income with mortality. The income mobility is operationalized as the interaction between parental and adult income. Our results show that the association between parental income and adult mortality is modest and largely operates through cognitive ability and adult educational attainment. However, our results do not provide support for there being an effect of intergenerational income mobility on adult mortality. In a Swedish cohort who grew up in a comparatively egalitarian society during the 1950s and 1960s, childhood economic conditions were found to play a distinct but relatively small role for later mortality.

Psychosocial School Conditions and Mental Wellbeing Among Mid-adolescents: Findings From the 2017/18 Swedish HBSC Study.

Objectives: To investigate mid-adolescent boys' and girls' experiences of school demands, teacher support, and classmate support, and explore the associations of these factors with mental wellbeing. Methods: Data were derived from the Swedish Health Behaviour in School-aged Children (HBSC) study of 2017/18, with information collected among 1,418 students in grade 9 (∼15-16 years). School demands, teacher support, and classmate support were measured by indices based on three items each. Mental wellbeing was measured by the Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS). Linear regression analyses were performed. Results: Higher demands were associated with lower mental wellbeing. Conversely, mental wellbeing increased with greater teacher support and classmate support. Interactions between demands and the support variables showed that at the lowest levels of teacher and of classmate support, mental wellbeing was low and not associated with school demands. With increasing levels of teacher and classmate support, the overall level of mental wellbeing increased and revealed an inverse association between school demands and mental wellbeing. Conclusion: The study contributes with knowledge about how psychosocial conditions in school may hinder or enhance wellbeing among students.

Sense of Unity and Self-Reported Health Among 15-year-Olds: Findings From the Swedish 2017/18 Health Behavior in School-Aged Children Study.

Objectives: Sense of unity refers to the positive feeling of being part of a larger social structure. This study aimed to investigate to what extent adolescents report sense of unity and if this differs across groups, and to assess the associations between sense of unity and self-reported health while taking into account sociodemographic characteristics and tangible social relationships. Methods: Data were obtained from the 2017/18 Swedish Health Behavior in School-aged Children study, using information collected among 15-year-old students (n = 1,392). Linear and binary logistic regression analyses were performed. Results: The participants reported overall high levels of sense of unity. Sense of unity did not differ by gender, but adolescents without an immigrant background and those with higher family affluence reported higher levels. Sense of unity was inversely associated with psychological complaints, somatic complaints, and less than good self-rated health, even when adjusting for sociodemographic characteristics and family, classmate, and teacher relationships. Conclusion: This study suggests that sense of unity may be an important social determinant for adolescent health. More research is needed on the origins and implications of sense of unity.

Teacher-Rated School Leadership and Adolescent Gambling: A Study of Upper Secondary Schools in Stockholm, Sweden.

So-called "effective schools" are characterised by properties such as a strong and purposeful school leadership and a favourable school ethos. In a previous study we showed that a school's degree of teacher-rated ethos was inversely associated with student gambling and risk gambling. Building on these findings, the current study aims to examine the associations that teachers' ratings of the school leadership share with gambling and risk gambling among students in the second grade of upper secondary school in Stockholm (age 17-18 years). Data were drawn from the Stockholm School Survey and the Stockholm Teacher Survey with information from 5191 students and 1061 teachers in 46 upper secondary schools. School-level information from administrative registers was also linked to the data. The statistical method was two-level binary logistic regression analysis. Teachers' average ratings of the school leadership were inversely associated with both gambling (OR 0.96, 95% CI 0.93-0.998, p = 0.039) and risk gambling (OR 0.94, 95% CI 0.89-0.99, p = 0.031) among upper secondary students, whilst adjusting for sociodemographic characteristics at the student and the school level. The findings lend further support to the hypothesis that characteristics of effective schools may reduce students' inclination to engage in gambling and risk gambling behaviours.

Problematic familial alcohol use and heavy episodic drinking among upper secondary students: a moderator analysis of teacher-rated school ethos.

OBJECTIVE: Building on findings reported in a previous publication, the objective of this study is to explore if teacher-rated indicators of school ethos modify the association between problematic familial alcohol use and heavy episodic drinking among upper secondary students. Data were based on combined information from two separate surveys conducted in 2016 among 4709 students and 1061 teachers in 46 Stockholm upper secondary schools, with linked school-level information from administrative registers. Multilevel binary logistic regression analyses were performed. RESULTS: Problematic familial alcohol use was associated with an increased likelihood of heavy episodic drinking among upper secondary students (OR 1.36, 95% CI 1.12-1.65). Cross-level interactions revealed that the association was weaker among students attending schools with higher levels of teacher-rated ethos. This was true for overall school ethos (OR 0.79, 95% CI 0.65-0.97) and for four of five studied sub-dimensions of ethos: staff stability (OR 0.78, 95% CI 0.65-0.95); teacher morale (OR 0.79, 95% CI 0.65-0.97); student focus (OR 0.80, 95% CI 0.65-0.97); and academic atmosphere (OR 0.79, 95% CI 0.65-0.96). The sub-dimension "structure and order for dealing with unwanted behaviour" did however not moderate the association between problematic familial alcohol use and heavy episodic drinking (OR 0.95, 95% CI 0.77-1.18).

Sexual jokes at school and students' life satisfaction: findings from the 2017/18 Swedish Health Behaviour in School-aged Children study.

OBJECTIVE: In a previous study we demonstrated that the occurrence of sexual jokes in the class was associated with higher levels of psychological health complaints. Building on and extending these findings, the aim of the current study was to examine if exposure to sexual jokes at the student and at the class level was inversely associated with students' life satisfaction. Data were derived from the 2017/18 Swedish Health Behaviour in School-aged Children (HBSC) study, with students aged 11, 13 and 15 years (n = 3710 distributed across 209 classes). Exposure to sexual jokes at the student level was captured by one item. Exposure to sexual jokes at the class level was calculated by aggregating this measure. The Cantril ladder was used to operationalise life satisfaction. Two-level logistic regression analyses were performed. RESULTS: Students who were exposed to sexual jokes at school were less likely to report high life satisfaction (OR 0.38, 95% CI 0.27-0.53). An inverse association was found between the class proportion of students who were exposed to sexual jokes and students' likelihood of reporting high life satisfaction, whilst adjusting for exposure to sexual jokes at the student level (OR 0.98, 95% CI 0.97-0.9994). The findings highlight the importance of promoting a school climate without sexual harassment.

Psychosocial Working Conditions in School and Life Satisfaction among Adolescents in Sweden: A Cross-Sectional Study.

Poor psychosocial working conditions in school have consistently been shown to be associated with adverse health among adolescents. However, the relationships between school demands, teacher support, and classmate support and positive aspects of health have not been explored to the same extent. The aim of this study was to examine differences in psychosocial working conditions in school and in life satisfaction by gender and by grade, and to investigate the association between psychosocial working conditions in school and life satisfaction among boys and girls, and among students in different grades. Data from the Swedish Health Behavior in School-Aged Children (HBSC) study of 2017/18 were used, consisting of 3614 students in Grades 5, 7, and 9 (~11, 13, and 15 years). Psychosocial working conditions in school were captured by indices of perceived school demands, teacher support, and classmate support. Life satisfaction was measured by the 11-step Cantril's ladder (using cutoffs at >5 and >8, respectively). Whereas girls reported higher school demands than boys, higher levels of teacher and classmate support were reported by boys. Students in lower grades reported lower school demands but higher levels of teacher and classmate support compared with students in higher grades. Boys and students in lower grades were more likely to report high life satisfaction compared with girls and students in higher grades. Results from binary logistic regression analyzes showed that school demands were inversely associated with life satisfaction, and that higher levels of teacher support and classmate support were associated with high life satisfaction. These results were found for both boys and girls, and for students in all grades. The findings indicate that schools have the potential to promote positive health among students.

Excellent Self-Rated Health among Swedish Boys and Girls and Its Relationship with Working Conditions in School: A Cross-Sectional Study.

The aim of this study was to investigate the extent to which school demands, teacher support, and classmate support were associated with excellent self-rated health among students, and to examine if any such statistical predictions differed by gender. Data were drawn from the Swedish Health Behaviour in School-aged Children (HBSC) study of 2017/18, performed among adolescents in grades five, seven, and nine (n = 3701). Linear probability models showed that school demands were negatively associated with excellent self-rated health, whereas teacher and classmate support showed positive associations. The link with school demands was stronger for girls than boys, driven by the finding that in grades five and nine, school demands were associated with excellent self-rated health only among girls. In conclusion, the study suggests that working conditions in school in terms of manageable school demands and strong teacher and classmate support may benefit adolescents' positive health. The finding that the link between school demands and excellent self-rated health was more evident among girls than among boys may be interpreted in light of girls' on average stronger focus on schoolwork and academic success. The study contributes to knowledge about how working conditions in school may impede or promote students' positive health.

The Role of Academic Achievement in the Relationship between School Ethos and Adolescent Distress and Aggression: A Study of Ninth Grade Students in the Segregated School Landscape of Stockholm.

Equitable access to high-quality schools is important for student achievement. However, the increasing attention placed on adolescent mental health promotion suggests that school contextual factors and school achievement may also play an important role for students' psychological well-being. This study examined the relationships between school ethos, academic achievement, psychological distress and aggressive behaviour among Swedish students, further considering the role of school sociodemographic composition. Analyses were based on two separate data collections in Stockholm, one among teachers (n = 2089) and the other among students aged 15-16 (n = 9776; 49.7% girls). Using multilevel structural equation modelling, the relations between teachers' reports of school ethos and students' reports of achievement, psychological distress and aggressive behaviour were tested. Analyses showed a positive relationship between a school's ethos and average academic achievement. At the school level, higher academic achievement was in turn associated with less psychological distress among students, providing an indirect pathway between school ethos and psychological distress. At the individual level, students with higher academic achievement reported less psychological distress and aggressive behaviour. These findings indicate that schools' value-based policies and practices can play a role for students' academic performance, and through this, for their psychological well-being.

Sexual jokes at school and psychological complaints: Student- and class-level associations.

Background: Students who are subjected to sexual harassment at school report lower psychological well-being than those who are not exposed. Yet, it is possible that the occurrence of sexual harassment in the school class is also stressful for those who are not directly targeted, with potential negative effects on well-being for all students. Aim: The aim was to examine whether exposure to sexual jokes at the student level and at the class level was associated with students' psychological complaints, and if these associations differed by gender. Method: Data from the Swedish Health Behaviour in School-aged Children (HBSC) of 2017/18 was used, with information from students aged 11, 13 and 15 years (N=3720 distributed across 209 classes). Psychological health complaints were constructed as an index based on four items. Exposure to sexual jokes at the student level was measured by one item, and at the class level as the class proportion of students exposed to sexual jokes, in per cent. Two-level linear regression analyses were performed.Results: Students who had been exposed to sexual jokes at school reported higher levels of psychological complaints, especially boys. Furthermore, the class proportion of students who had been exposed to sexual jokes was also associated with psychological complaints, even when adjusting for student-level exposure to sexual jokes, gender, grade and class size. Conclusions: Sexual jokes seem to be harmful for those who are directly exposed, but may also affect indirectly exposed students negatively. Thus, a school climate free from sexual jokes may profit all students.

School ethos and adolescent gambling: a multilevel study of upper secondary schools in Stockholm, Sweden.

BACKGROUND: Gambling is not uncommon among adolescents, and a non-trivial minority has serious problems with gambling. Therefore, enhanced knowledge about factors that may prevent against problematic gambling among youth is needed. Prior research has shown that a strong school ethos, which can be defined as a set of attitudes and values pervading at a school, is associated with a lower inclination among students to engage in various risk behaviours. Knowledge about the link between school ethos and adolescent gambling is however scarce. The aim of the study was to investigate the association between teacher-rated school ethos and student-reported gambling and risk gambling, when controlling also for sociodemographic characteristics at the student- and the school-level. METHODS: Data from two separate cross-sectional surveys were combined. The Stockholm School Survey (SSS) was performed among 5123 students (aged 17-18 years) in 46 upper secondary schools, and the Stockholm Teacher Survey (STS) was carried out among 1061 teachers in the same schools. School ethos was measured by an index based on teachers' ratings of 12 items in the STS. Adolescent gambling and risk gambling were based on a set of single items in the SSS. Sociodemographic characteristics at the student-level were measured by student-reported information from the SSS. Information on sociodemographic characteristics at the school-level was retrieved from administrative registers. The statistical method was multilevel regression analysis. Two-level binary logistic regression models were performed. RESULTS: The analyses showed that higher teacher ratings of the school's ethos were associated with a lower likelihood of gambling and risk gambling among students, when adjusting also for student- and school-level sociodemographic characteristics. CONCLUSIONS: This study showed that school ethos was inversely associated with students' inclination to engage in gambling and in risk gambling. In more general terms, the study provides evidence that schools' values and norms as reflected by the teachers' ratings of their school's ethos have the potential to counteract unwanted behaviours among the students.

School Ethos and Recurring Sickness Absence: A Multilevel Study of Ninth-Grade Students in Stockholm.

School absence has been identified as a severe problem in Sweden, both at the individual level and for society as a whole. Despite the multitude and complexity of reasons behind school absence, health-related problems are likely to be one important determinant. This indicates that knowledge about factors that may contribute to preventing health-related absence among students is relevant. The aim was to investigate whether a higher level of teacher-reported school ethos was associated with less recurring sickness absence among students. Data from four cross-sectional surveys performed in 2014 and 2016 were combined. The Stockholm School Survey was carried out among 9482 ninth-grade students (ages 15-16 years) in 150 school units, and the Stockholm Teacher Survey was performed among 2090 teachers in the same units. School ethos was operationalised by an index of 12 teacher-reported items that was aggregated to the school-level. Recurring student sickness absence was captured by self-reports and defined as absence on >10 occasions during the current school year. Two-level logistic regressions were performed. The results show that about 9.5% of the students reported recurring sickness absence. Students attending schools with higher levels of teacher-rated school ethos were less likely to reporting recurring sickness absence than those attending schools with lower levels of ethos, even when adjusting for potential confounders (OR 0.79, 95% CI 0.65-0.97). In conclusion, recurring sickness absence was less common among students attending schools with higher levels of teacher-rated ethos. The findings suggest that schools may contribute to promoting student health.

School Choice at a Cost? Academic Achievement, School Satisfaction and Psychological Complaints among Students in Disadvantaged Areas of Stockholm.

School choice allows students from more disadvantaged district areas in metropolitan Swedish cities to commute to more prestigious schools outside of their residential area. This study examined how such students fare compared to their peers who attend more deprived schools in their own district area. Multilevel analysis was applied, estimating 2-level random intercept linear regression models based on cross-sectional survey data collected among ninth grade students in 2014 and 2016 (n = 2105). Analyses showed that students living in relatively disadvantaged district areas of Stockholm who chose to attend more prestigious schools outside of their residential area performed better academically compared to students who opted to remain at more deprived schools in their catchment area, an association that was partly mediated by school quality in terms of teacher-rated school ethos. Yet, commuting students reported lower school satisfaction and more psychological complaints than students who stayed behind, even when taking academic achievement and school ethos into account. The association with psychological complaints was partly mediated by school satisfaction. Thus, the academic gain associated with having chosen to commute from a disadvantaged area to a more prestigious school does not appear to translate into higher school satisfaction and better psychological well-being.

School effectiveness and students' future orientation: A multilevel analysis of upper secondary schools in Stockholm, Sweden.

INTRODUCTION: Future orientation (FO) refers to individuals' beliefs and feelings about their future. Earlier research has primarily investigated correlates of FO at the individual and family level, but it seems likely that FO is also shaped by other central agents or institutions, such as the school. Earlier studies have found positive associations between "school effectiveness" and student performance, and negative associations in relation to e.g., bullying, delinquency, and health risk behaviors. The current study investigated three teacher-reported features of school effectiveness - school leadership, teacher cooperation and consensus, and school ethos - and their links with student-reported FO. METHODS: Survey data were collected in 2016 among 5131 students (aged 17-18 years) and 1061 teachers in 46 upper secondary schools in Stockholm, Sweden, and merged with school-level register data. Two-level binary logistic regression analyses were performed. RESULTS: The analyses showed that higher teacher ratings of school leadership and school ethos were associated with a greater likelihood of reporting an optimistic FO among students. Teacher cooperation and consensus was however not associated with students' FO. CONCLUSION: The findings indicate that the school environment contributes to shaping students' beliefs about their future. Thus, enhancing features of school effectiveness may be a way of promoting a positive development and brighter objective future prospects for the young, via pathways such as good student-teacher relations and academic motivation and achievement.
