RESUMEN
AIMS: Most previous prospective studies have examined workplace social capital as a resource of the individual. However, literature suggests that social capital is a collective good. In the present study we examined whether a high level of workplace aggregated social capital (WASC) predicts a decreased risk of individual-level long-term sickness absence (LTSA) in Danish private sector employees. METHODS: A sample of 2043 employees (aged 18-64 years, 38.5% women) from 260 Danish private-sector companies filled in a questionnaire on workplace social capital and covariates. WASC was calculated by assigning the company-averaged social capital score to all employees of each company. We derived LTSA, defined as sickness absence of more than three weeks, from a national register. We examined if WASC predicted employee LTSA using multilevel survival analyses, while excluding participants with LTSA in the three months preceding baseline. RESULTS: We found no statistically significant association in any of the analyses. The hazard ratio for LTSA in the fully adjusted model was 0.93 (95% CI 0.77-1.13) per one standard deviation increase in WASC. When using WASC as a categorical exposure we found a statistically non-significant tendency towards a decreased risk of LTSA in employees with medium WASC (fully adjusted model: HR 0.78 (95% CI 0.48-1.27)). Post hoc analyses with workplace social capital as a resource of the individual showed similar results. CONCLUSIONS: WASC did not predict LTSA in this sample of Danish private-sector employees.

BACKGROUND: Symptoms of depression and musculoskeletal pain have both been found to be associated with increased risk of long term sickness absence (LTSA). The comorbidity between depression and pain i.e. simultaneous presence of both symptoms, is well established in the literature. The aim for the current investigation was to investigate whether the presence of comorbid pain influences the associations between depressive symptoms and LTSA or if the presence of comorbid depressive symptoms influences associations between musculoskeletal pain and LTSA. METHODS: A sample of 6572 Danish female health care workers responding to a questionnaire about health and working conditions were followed up in a national register of social transfer payments (DREAM) for 550 days. We estimated the risk for LTSA of four weeks or more, associated with depressive symptoms and number of musculoskeletal pain locations using a Cox proportional hazards model allowing multiple observations per individual. We conducted a test for multiplicative interaction between musculoskeletal pain locations and depressive symptoms, and presented stratified regression models to facilitate the interpretation of the results. RESULTS: The severity of depressive symptoms was correlated with the number of pain locations reported (Spearman's rho = .24, p < 0.001). We found a significant multiplicative interaction between depressive symptoms and musculoskeletal pain in predicting the risk of LTSA. Depressive symptoms and number of musculoskeletal pain locations were associated with increased risk of LTSA for individuals who did not have comorbid symptoms. However, we found no significant associations between the two predictors and LTSA among participants who reported comorbid symptoms. CONCLUSIONS: The risk of LTSA associated with depressive symptoms and musculoskeletal pain appears to be moderated by the presence of comorbid symptoms. The modified risk for LTSA among workers with comorbid symptoms requires further investigation.

OBJECTIVES: The aim of the present study was to examine the factor structure, model-based reliability, measurement invariance and concurrent validity of the five-item version of the Mindfulness Attention Awareness Scale (MAAS) in Norwegian adolescents. METHODS: An initial pilot study was carried out using a sample of 77 fifteen year olds. For the main analyses, a sample of 2140 Norwegian adolescents was used who participated in the cross-sectional Health Behaviour in School-Aged Children (HBSC) study. All participants were asked to complete a questionnaire. RESULTS: Confirmatory factor analyses found support for the one-factor structure of the five-item version of the MAAS. Acceptable model fit was found in both the pilot sample (χ2=6.48, df=5, p=0.26; root mean square error of approximation [RMSEA]=0.06; comparative fit index [CFI]=0.99; standardised root mean square residual [SRMR]=0.03) and the HBSC sample (χ2=27.1, df=4, p<0.001; RMSEA=0.05; CFI=0.99; SRMR=0.01). The model-based reliability of the scale was good (ω=0.84 and ω=0.81, respectively). Scalar measurement invariance was established for sex, age and material affluence. Finally, the five-item MAAS displayed concurrent validity through moderate negative associations with health complaints ( r=-0.44; p<0.001) and school stress ( b=-0.44, p<0.001), and a positive moderate correlation with life satisfaction ( r=0.26; p<0.001). CONCLUSIONS: The five-item version of the MAAS is an adequate measure of mindfulness in Norwegian adolescents. Due to the brief nature of the scale, it can easily be included in epidemiological and clinical studies with an interest for trait mindfulness. The five-item MAAS may therefore have great potential to facilitate more knowledge about the role of mindfulness in adolescent health.

BACKGROUND: There is a higher prevalence of anxiety and depression among adults with lower educational attainment. Delayed completion of high school (HS) is common and represents a potentially complicating factor in the relationship between educational attainment and anxiety and depression. This study aims to investigate whether delayed HS completion is associated with symptom levels of anxiety and depression in adulthood and whether it interacts with later educational attainment in predicting symptom-levels of anxiety and depression in adulthood. METHODS: The sample consisted of 10 149 participants from the Nord-Trøndelag Health Survey (HUNT 3) between 30 and 46 years of age in 2006. The outcome variables were symptoms of anxiety and depression as measured by the HADS scale. Variables measuring educational attainment were obtained from the National Educational Database in Norway. We used linear regression to estimate associations between educational attainment, delayed HS completion and symptom levels of anxiety and depression in adulthood. RESULTS: We found delayed HS completion to be associated with higher symptom levels of both anxiety and depression. There was a dose-response association suggesting that each additional year of delay in HS was associated with higher symptom levels for both anxiety and depression. Mean symptom levels of both anxiety and depression were significantly lower among individuals who completed HS within a normative timeframe vs those who were substantially delayed in their HS completion. For anxiety symptoms, we found a statistically significant interaction between delayed HS completion and later educational attainment. This interaction suggested that individuals with a combination of being delayed in HS and having no higher educational attainment had significantly higher levels of anxiety symptoms than all other combinations of later educational attainment and normative/delayed HS completion. For depression, associations between predictors and symptom levels were additive. CONCLUSIONS: Delayed HS completion is associated with symptom levels of both depression and anxiety and interacts with later educational attainment in predicting symptom levels of anxiety. Individuals with a combination of delayed HS completion and lower educational attainment had particularly high symptom levels of anxiety.

This study aimed to examine the long-term prediction of well-being and internalizing symptoms from trajectories of externalizing behavior problems in 921 children from a population-based sample. We found that a high stable trajectory of externalizing behavior from infancy (age 1.5) to mid-adolescence (age 14.5) predicted lower scores on life satisfaction and flourishing for both girls and boys (age 18.5). The high stable trajectory also predicted higher levels of depressive symptoms in boys and anxiety symptoms in girls (age 18.5). The findings are noteworthy as they document how a person-oriented study of externalizing behavior problems starting in infancy can predict well-being and internalizing in late adolescence. The findings underline the importance of early health promotion and problem intervention efforts.

BACKGROUND: The use of electronic media has been found to be a risk factor for higher BMI and for being overweight. Physical activity has been found to be associated with lower BMI and lower risk for being overweight. Little is known about whether the associations between physical activity and electronic media use are additive or interactive in predicting BMI and risk for overweight among adolescents. METHODS: The data used in this study stem from the 2009/2010 survey of "Health Behaviour in School-aged Children (HBSC) study: A WHO Cross-National Survey. The sample consisted of 107184 13 and 15 year students from 30 different countries. Multilevel regression models were used to produce the presented estimates. RESULTS: Overall, 18% of boys and 11% of girls were classified as overweight. EM use was found to be associated with increased BMI z-scores and odds for overweight among both boys and girls who did not comply with physical activity guidelines. Among physically active adolescents, EM was found to be significantly associated with BMI or odds for overweight among girls, but not among boys. CONCLUSION: While the usage of EM appear to be inconsequential for BMI and the risk of overweight among physically active boys, we find evidence indicating that EM use is associated with BMI and risk for overweight among girls, including those who report complying with MVPA guidelines.

BACKGROUND: Recent studies have suggested that functional classifications of aggression should be used to improve the understanding of the heterogeneity of aggression and its management, among inpatients in psychiatric hospitals. AIMS: Our aim was to examine a theoretically derived three-factor model for conceptualising aggressive incidents by inpatients as irritable, instrumental or defensive. METHODS: As part of the routine assessments in a forensic psychiatric high security ward, staff filled out a questionnaire on motives for aggression after all violent incidents. A total of 1652 incidents from 28 patients were analysed by means of exploratory and confirmatory factor analyses. RESULTS: Support was found for the three-factor model. For the most part, the scale items loaded on the factors as predicted, and the model was able to explain 61% of the data variance. Irritable incidents were the most common, but elevated scores for instrumental characteristics were found as well. High psychopathy scores were associated with incidents scoring high values on both irritable and instrumental dimensions, and low values on the defensive dimensions. CONCLUSIONS: Confirming these three dimensions of inpatient aggressive incidents may help caregivers' understanding of aggressive behaviour. If confirmed in future studies, this dimensional approach may prove useful for the management of aggressive inpatients.

BACKGROUND: This study proposes a new approach for investigating bias in self-reported data on height and weight among adolescents by studying the relevance of participants' self-reported response capability. The objectives were 1) to estimate the prevalence of students with high and low self-reported response capability for weight and height in a self-administrated questionnaire survey among 11-15 year old Danish adolescents, 2) to estimate the proportion of missing values on self-reported height and weight in relation to capability for reporting height and weight, and 3) to investigate the extent to which adolescents' response capability is of importance for the accuracy and precision of self-reported height and weight. Also, the study investigated the impact of students' response capability on estimating prevalence rates of overweight. METHODS: Data was collected by a school-based cross-sectional questionnaire survey among students aged 11-15 years in 13 schools in Aarhus, Denmark, response rate =89%, n = 2100. Response capability was based on students' reports of perceived ability to report weight/height and weighing/height measuring history. Direct measures of height and weight were collected by school health nurses. RESULTS: One third of the students had low response capability for weight and height, respectively, and every second student had low response capability for BMI. The proportion of missing values on self-reported weight and height was significantly higher among students who were not weighed and height measured recently and among students who reported low recall ability. Among both boys and girls the precision of self-reported height and weight tended to be lower than among students with low response capability. Low response capability was related to BMI (z-score) and overweight prevalence among girls. These findings were due to a larger systematic underestimation of weight among girls who were not weighed recently (-1.02 kg, p < 0.0001) and among girls with low recall ability for weight (-0.99 kg, p = 0.0024). CONCLUSION: This study indicates that response capability may be relevant for the accuracy of girls' self-reported measurements of weight and height. Consequently, by integrating items on response capability in survey instruments, participants with low capability can be identified. Similar analyses based on other and less selected populations are recommended.

Based on data from a 17-year longitudinal study of 1083 adolescents, from the ages of 13 to 30 years, the average development of self-reported global self-esteem was found to be high and stable during adolescence. However, there is considerable inter-individual variance in baseline and development of global self-esteem. This study used latent growth mixture modelling to characterize three trajectory classes of global self esteem between ages 14 and 23 years: consistently high, chronically low, and U-shaped. The respondents in three classes showed statistically significant different levels of life satisfaction, depressive mood, somatic complaints and insomnia at age 30. Attempts to predict trajectories from age 13 were only partially successful, with body image, relations with parents and frequency of physical activity as the significant predictors.

The trajectory of relationship satisfaction among married and cohabiting women in their transition to parenthood was compared in a potential sample of 71,504 women taking part in the Norwegian Mother and Child Cohort Study (MoBa). Prospective longitudinal data were collected in 4 waves over a 2-year period starting 6 months prebirth. Results from latent curve models suggested that married and cohabiting women experience similar negative change in relationship satisfaction during the transition to parenthood. However, cohabiting women start off and stay less satisfied throughout the transition period, suggesting the presence of a negative cohabitation effect that prevailed after controlling for various covariates. Extending investigation on the cohabitation effect to the transition to parenthood, and replicating it in a Scandinavian context, is discussed in relation to the understanding of what causes the cohabitation effect, and its clinical implications.

BACKGROUND: In Australia and the USA, national guidelines exist for limiting children's screen-exposure to two hours per day. This study aims to determine whether exceeding the suggested guidelines for screen-based sedentary behavior is associated with reduced levels of physical activity across different geographical regions. METHODS: Data material were taken from the 2005/2006 survey of "Health Behaviour in School-aged Children (HBSC) study; A WHO cross-National Survey". Data were collected through questionnaires from 11-,13- and,15- year olds. The final sample included 200,615 adolescents from 39 different countries in Europe and North America. Gender and country stratified analyses regressed time spent in leisure-time vigorous physical activity (VPA) and days of 60 minutes moderate to vigorous physical activity (MVPA) on time spent in screen-based sedentary behaviors. To simplify interpretation, the estimates from each country were pooled using a meta-analytic procedure. RESULTS: Exceeding 2 hrs of daily total screen-time was negatively associated with MVPA for both boys and girls, and with VPA for girls. When investigating the different types of screen-based behaviors separately, exceeding 2 hrs daily of TV viewing was associated with less MVPA for both boys and girls and less VPA for girls. Gaming was associated with less MVPA and VPA for boys, and non-gaming computer use was associated with higher levels of VPA for both genders. Stronger negative associations between physical activity and screen-based sedentary behaviors were found in countries where mean levels of physical activity were relatively high. The association between physical activity and sedentary behavior was not significantly associated with national levels of screen-based sedentary behaviors. CONCLUSIONS: The displacement mechanism does not appear to be universal across countries. On a national level, negative associations between physical activity and screen-based sedentary behaviors are less likely to be found in countries with relatively low levels of physical activity. Consequently, national guidelines for limiting children and adolescents time in screen-based sedentary behavior may not be conducive to increasing levels of physical activity in all countries.
RESUMEN
BACKGROUND: Previous studies have shown that adolescent mental health problems are associated with lower employment probabilities and risk of unemployment. The evidence on how earnings are affected is much weaker, and few have addressed whether any association reflects unobserved characteristics and whether the consequences of mental health problems vary across the earnings distribution. METHODS: A population-based Norwegian health survey linked to administrative registry data (N=7885) was used to estimate how adolescents' mental health problems (separate indicators of internalising, conduct, and attention problems and total sum scores) affect earnings (≥30â years) in young adulthood. We used linear regression with fixed-effects models comparing either students within schools or siblings within families. Unconditional quantile regressions were used to explore differentials across the earnings distribution. RESULTS: Mental health problems in adolescence reduce average earnings in adulthood, and associations are robust to control for observed family background and school fixed effects. For some, but not all mental health problems, associations are also robust in sibling fixed-effects models, where all stable family factors are controlled. Further, we found much larger earnings loss below the 25th centile. CONCLUSIONS: Adolescent mental health problems reduce adult earnings, especially among individuals in the lower tail of the earnings distribution. Preventing mental health problems in adolescence may increase future earnings.

PURPOSE: Engaging in prolonged screen-time behaviors (STBs) is detrimental for health. The objective of the present analyses was to examine temporal trends in TV viewing and computer use among adolescents across 30 countries. METHODS: Data were derived from the cross-national Health Behaviour in School-aged Children study. Data on TV viewing and computer use for gaming and nongaming purposes were collected in 2002 (n = 139,725 [51.4% girls]), 2006 (n = 149,251 [51.3% girls]), and 2010 (n = 154,845 [51.2% girls]). The temporal trends in TV viewing and computer use were each tested for all countries combined and for each individual country by sex-specific univariate analysis of variance. RESULTS: Between 2002 and 2010, TV viewing decreased slightly in most of the 30 countries among both boys and girls. This decrease was more than offset by a sharp increase in computer use, which was consistent across all countries. Overall, boys reported more hours of STBs. They also reported a slightly larger decrease in TV viewing and slightly larger increase in computer use. STBs were generally more frequent on weekend days. CONCLUSIONS: The overall cross-national increases in STBs should be a call to action for public health practitioners, policy-makers, and researchers that interventions specifically focused on reducing STBs in youth are sorely needed. Because all countries experienced a trend in the same direction, it might be fruitful to learn more about the determinants of STBs among those countries in which hours of STBs are generally low as compared with other countries.

OBJECTIVES: To examine overweight prevalence and its association with demographic and lifestyle factors in 11-15 year olds in the HBSC 2005-2006 survey. METHODS: Self-reports of height, weight, eating patterns, physical activity and sedentary behaviours were obtained from nationally representative samples in 41 countries (n=204,534). RESULTS: Overweight prevalence was highest in USA (28.8 %) and lowest in Latvia (7.6 %). In most countries, overweight was more prevalent in boys than girls. Overweight was consistently negatively associated with breakfast consumption and moderate to vigorous physical activity; OR range: 0.48-0.79 and 0.50-0.78, respectively. CONCLUSION: Overweight prevalence in youth remained high across the countries examined. The primary factors linked to overweight were breakfast consumption and physical activity. These data should contribute to formulating preventive programs and policies.
