OBJECTIVE The aim of the present study was to examine the association of insomnia symptoms with demographic and physical and mental conditions in a large population-based study. METHODS Cross-sectional data on insomnia and comorbid conditions were gathered from 47,700 individuals aged 20-89 in Norway. Comorbid conditions included anxiety and depression(More)
The fetal origins of adult disease (FOAD) hypothesis suggests that risk factors from intrauterine environmental exposures affect the fetus' development during sensitive periods, and increases the risk of specific diseases in adult life. This link was initially observed between prenatal exposures and adult coronary heart disease, but corresponding(More)
PURPOSE It is generally accepted that mental health problems are unequally distributed across population strata defined by socioeconomic status (SES), with more problems for those with lower SES. However, studies of this association in children and adolescents are often restricted by the use of global measures of mental health problems and aggregation of(More)
Cigarette smoking is increased in people with trait anxiety and anxiety disorders, however no longitudinal data exist illuminating whether smoking in adolescence can influence the developmental trajectory of anxiety symptoms from early vulnerability in infancy to adult anxiety expression. Using The Tracing Opportunities and Problems in Childhood and(More)
OBJECTIVE To examine the hypothesized effect of health anxiety on subsequent disability pension award. Mental disorders are consistently underrecognized in general health care, leading to underestimation of its effects on related social security expenditures. According to medicolegal diagnoses for disability pension award, there are almost no awards of(More)
OBJECTIVE Rates of disability pension (DP) awards remain high in most developed countries. We aimed to estimate the impact of anxiety and depression on DPs awarded both for mental and for physical diagnoses and to estimate the relative contribution of sub case-level anxiety and depression compared with case-level symptom loads. METHODS Information from a(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)
OBJECTIVE Depression and insomnia are closely linked, yet our understanding of their prospective relationships remains limited. The aim of the current study was to investigate the directionality of association between depression and insomnia. METHODS Data were collected from a prospective population-based study comprising the most recent waves of the(More)
BACKGROUND Studies on adolescent smoking indicate that the smoking behaviours of their parents, siblings and friends are significant micro-level predictors. Parents' socioeconomic status (SES) is an important macro-level predictor. We examined the longitudinal relationships between these predictors and the initiation and development of adolescents' smoking(More)
BACKGROUND Improvements in treatment of mental disorders are repeatedly called for. General practitioners (GPs) are responsible for the majority of treatment of mental disorders. Consequently, we interviewed GPs about their opinions on how treatment of mental disorders in primary health care contexts could be improved. METHODS Among GPs affiliated within(More)
