BACKGROUND The Global Burden of Disease Study 2013 (GBD 2013) aims to bring together all available epidemiological data using a coherent measurement framework, standardised estimation methods, and transparent data sources to enable comparisons of health loss over time and across causes, age-sex groups, and countries. The GBD can be used to generate summary(More)
Background Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specifi c mortality for 249 causes in 195 countries and territories from 1980 to 2015. These(More)
OBJECTIVE To examine and compare the prospective effect of the common mental disorders (CMD) anxiety and depression on duration and recurrence of sickness absence (SA), and to investigate whether the effect of CMD on SA is detectable over time. METHOD Information from a large epidemiological health study (N = 13 436) was linked with official records of SA(More)
OBJECTIVES Mental disorders are prevalent diagnoses in disability benefit statistics, with awards often granted at younger age than for other diagnoses. We aimed to compare the number of lost working years following disability benefit award for mental disorders versus other diagnostic groups. METHODS Data from the complete Norwegian official registry over(More)
The authors aimed to examine whether nonparticipation in a population-based health study was associated with poorer health status; to determine whether specific health problems were overrepresented among nonparticipants; and to explore potential consequences of participation bias on associations between exposures and outcomes. They used data from the(More)
BACKGROUND Common mental disorders (CMDs) are associated with occupational impairment and the receipt of disability benefits (DBs). Little is known about the relationship between personality disorders (PDs) and work disability, and whether the association between CMDs and work disability is affected by the presence of co-morbid PDs. The aim of this study(More)
BACKGROUND The social gradient in disability pension is well recognized, however mechanisms accounting for the gradient are largely unknown. The aim of this study was to examine the association between occupational class and subsequent disability pension among middle-aged men and women, and to what extent work-related factors accounted for the association.(More)
BACKGROUND Low socioeconomic status is a known risk factor for disability pension, and is also associated with health problems. To what degree health problems can explain the increased risk of disability pension award associated with low socioeconomic status is not known. METHODS Information on 15,067 participants in the Hordaland Health Study was linked(More)
The aim of the study was to examine the psychometric properties of the CRAFFT-questionnaire, and its concurrent validity with self-reported measures of alcohol consumption and illicit drug use ever among Norwegian adolescents. This study employs data from the ung@hordaland survey (N=9680). The concurrent validity of the CRAFFT-questionnaire was examined(More)
BACKGROUND Aggregated measures are often employed when prevalence, risk factors and consequences of alcohol use in the population are monitored. In order to avoid time-dependent bias in aggregated measures, reference periods which assess alcohol use over longer time-periods or measures assessing typical alcohol use are considered superior to reference(More)
