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.

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.

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.

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.

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

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. 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.
