Changes in the association between educational achievement, attainment and subsequent mental health: A survival analysis of 21 Swedish graduation cohorts.

Background: Low academic achievement and low educational attainment in adolescence is associated with higher risks of internalizing disorders later in life. However, less is known regarding if these associations vary over time across cohorts. The aim of this study was to investigate temporal changes in the association between academic achievement or educational attainment and subsequent inpatient treatment for internalizing disorders among Swedish youths.

Associations between academic achievement and internalizing disorders in Swedish students aged 16 years between 1990 and 2018.

Background: Rising rates of internalizing disorders and rising rates of school failure among adolescents are growing concerns. Despite the strong association between academic achievement and internalizing disorders, possible links between these two trends have not been investigated. Thus, the aim of this study was to investigate the development of the cross-sectional associations between academic achievement and internalizing disorders in Swedish students aged 16 years between 1990 and 2018.

Trends in adolescent psychosomatic complaints: a quantile regression analysis of Swedish HBSC data 1985-2017.

Background And Aims: According to recent criticism, survey-based measures of adolescent psychosomatic complaints have poor content validity insofar as they conflate trivial with severe complaints. It is argued that this means that estimates of prevalence and trends in complaints may reflect trivial complaints that are not indicators of health problems. In this study, two observable implications of this criticism were investigated: (a) that self-reported psychosomatic complaints should have a bimodal distribution; and (b) that the increase in complaints over time should be of approximately equal size throughout the distribution of complaints.

Recurrent pain in school-aged children: a longitudinal study focusing on the relation to academic achievement.

Recurrent pain is an increasing public health problem among school-aged children, with potential negative impact on children's daily lives, such as schoolwork. The overall aim of this study was to investigate whether recurrent pain in school year 6 was associated with poorer academic achievement at the end of elementary school in school year 9. The study was a follow-up study based on data from " The Study of Health in School-Aged Children from Umeå".

Feasibility, reliability and validity of the health-related quality of life instrument Child Health Utility 9D (CHU9D) among school-aged children and adolescents in Sweden.

Background: This study was conducted in a general population of schoolchildren in Sweden, with the aim to assess the psychometric properties of a generic preference-based health related quality of life (HRQoL) instrument, the Swedish Child Health Utility 9D (CHU9D), among schoolchildren aged 7-15 years, and in subgroups aged 7-9, 10-12 and 13-15 years.

Methods: In total, 486 school aged children, aged 7-15 years, completed a questionnaire including the CHU9D, the Pediatric quality of life inventory 4.0 (PedsQL), KIDSCREEN-10, questions on general health, long-term illness, and sociodemographic characteristics.

The Bidirectional Relationship Between Subjective Well-Being and Academic Achievement in Adolescence.

The well-being of young people in relation to their school performance has received increased attention in recent years. However, there is a lack of knowledge about the longitudinal and reciprocal relationship between adolescents' subjective well-being and their academic achievements. The current study examined the bidirectional relationship between subjective well-being and academic achievement across two timepoints (T1 and T2) during the course of mid to late adolescence, i.

Hypophosphatemic Hypovitaminosis D Induces Osteomalacia in the Adult Female Rat.

Osteomalacia is a bone-demineralizing disease of adulthood, often caused by hypovitaminosis D. Current animal models of the disease mimic osteomalacia as a consequence of gastric bypass or toxic exposure to metals, but a relevant model of diet-induced osteomalacia is lacking. For that purpose, 7-month-old female Sprague Dawley rats were randomly assigned into 2 weight-stratified groups and maintained for 4 months on synthetic diets containing negligible or normal levels of vitamin D.

School-related physical activity interventions and mental health among children: a systematic review and meta-analysis.

Background: Low levels of physical activity, sedentary behaviour and mental health problems are issues that have received considerable attention in the last decade. The aim of this systematic review and meta-analysis was to investigate effects of interventions targeting school-related physical activity or sedentary behaviour on mental health in children and adolescents and to identify the features of effective interventions.

Methods: Scientific articles published between January 2009 and October 2019 fulfilling the following criteria were included: general populations of children and adolescents between age 4 and 19, all types of school-related efforts to promote physical activity or reduce sedentary behaviour.

Health-Related Quality of Life in Children With Low Language or Congenital Hearing Loss, as Measured by the PedsQL and Health Utility Index Mark 3.

Objectives: To examine health-related quality of life (HRQoL) in young children with low language or congenital hearing loss and to explore the value of assessing HRQoL by concurrently administering 2 HRQoL instruments in populations of children.

Methods: Data were from 2 Australian community-based studies: Language for Learning (children with typical and low language at age 4 years, n = 1012) and the Statewide Comparison of Outcomes study (children with hearing loss, n = 108). HRQoL was measured using the parent-reported Health Utilities Index Mark 3 (HUI3) and the Pediatrics Quality of Life Inventory 4.

Perceived problems with academic achievement in school-aged children with recurrent pain - a longitudinal study.

The overall aim was to explore the relationship between recurrent pain and perceived problems with academic achievement among boys and girls in middle and late elementary school. This 3-year follow-up study was based on data from the Study of Health in School-aged Children from Umeå (Sweden) and included children attending grade 6 in years 2003 and 2006, and a follow-up 3 years later in grade 9 ( = 1524, participation rate 90%). Recurrent pain (head, stomach or back) at least doubled the odds of concurrent- and subsequent perceived problems with academic achievement.

The interplay between national and parental unemployment in relation to adolescent life satisfaction in 27 countries: analyses of repeated cross-sectional school surveys.

Background: Previous research shows that parental unemployment is associated with low life satisfaction in adolescents. It is unclear whether this translates to an association between national unemployment and adolescent life satisfaction, and whether such a contextual association is entirely explained by parental unemployment, or if it changes as a function thereof. For adults, associations have been shown between unemployment and mental health, including that national unemployment can affect mental health and life satisfaction of both the employed and the unemployed, but to different degrees.

Recurrent Pain and Academic Achievement in School-Aged Children: A Systematic Review.

Recurrent pain and school failures are common problems in children visiting the school nurses office. The overall aim of the current study was to investigate the relationship between recurrent pain and academic achievement in school-aged children. Literature was searched in seven electronic databases and in relevant bibliographies.

Preteen children's health related quality of life in Sweden: changes over time and disparities between different sociodemographic groups.

Background: Assessing disparities in health-related quality of Life (HRQoL) is important as a part of health-related disparities in the society. The aim of this study was to explore HRQoL among 12-year-olds in Sweden in terms of differences between years 2005 and 2009 and disparities related to sociodemographic background.

Methods: During the school years 2005 and 2009, a total of 18,325 sixth grade students in Sweden were invited to a celiac disease screening study; 13,279 agreed to participate.

School experiences in relation to emotional and conduct problems in adolescence: a 3-year follow up study.

Background: Mental health in adolescents has become a major public health issue. This study examined school experiences in relation to mental health (emotional problems and conduct problems) from early to middle adolescence.

Methods: This longitudinal 3-year follow up study used data from the Swedish Study of Health in School Children in Umeå.

Education system stratification and health complaints among school-aged children.

Research shows that the school environment is an important social determinant of health among children and adolescents. However, we know virtually nothing of the health consequences of national education systems and policies, for example the stratification of pupils by academic ability. This study aimed to investigate if education system stratification is related to self-reported psychological and somatic health complaints of pupils aged 11 to 15, and social inequalities in such health complaints.

Correction to: Health-related quality of life in girls and boys with juvenile idiopathic arthritis: self- and parental reports in a cross-sectional study.

Bone turnover is altered in transgenic rats overexpressing the P2Y2 purinergic receptor.

It is now widely recognized that purinergic signaling plays an important role in the regulation of bone remodeling. One receptor subtype, which has been suggested to be involved in this regulation, is the P2Y2 receptor (P2Y2R). In the present study, we investigated the effect of P2Y2R overexpression on bone status and bone cell function using a transgenic rat.

School-based systems change for obesity prevention in adolescents: outcomes of the Australian Capital Territory 'It's Your Move!'.

Objective: The Australian Capital Territory 'It's Your Move!' (ACT-IYM) was a three-year (2012-2014) systems intervention to prevent obesity among adolescents.

Methods: The ACT-IYM project involved three intervention schools and three comparison schools and targeted secondary students aged 12-16 years. The intervention consisted of multiple initiatives at individual, community, and school policy level to support healthier nutrition and physical activity.

P2X7Rs are involved in cell death, growth and cellular signaling in primary human osteoblasts.

The ionotropic ATP-gated P2X7 receptor (P2X7R) is involved in the regulation of many physiological functions including bone metabolism. Several studies on osteoblasts from rodents and human osteoblast-like cell lines have addressed the expression and function of P2X7R on these bone-forming cells however; its role in human primary osteoblasts has not yet been reported. The aim of this study was to assess the expression of the P2X7R in bone marrow-derived stromal cells and in primary human trabecular osteoblasts and to determine the function in bone formation and cell signaling.
