BACKGROUND Because of the quick development and widespread use of mobile phones, and their vast effect on communication and interactions, it is important to study possible negative health effects of mobile phone exposure. The overall aim of this study was to investigate whether there are associations between psychosocial aspects of mobile phone use and(More)
The aim of the study was to evaluate eight questions concerning physical loads, used in public health questionnaires. Working women and men (203) completed a self-administered questionnaire twice, following a test-retest method. The questions were also validated with a structured interview. Response agreement was calculated with Cohen's kappa statistics(More)
BACKGROUND Segregation of men and women into different jobs is often cited as one of the most plausible explanations for gender differences in exposure and musculoskeletal disorders. METHODS Direct measurements of sitting, arm, and trunk postures were taken with two different technical instruments on 156 subjects (78 matched pairs of one female and one(More)
BACKGROUND We have previously studied prospective associations between computer use and mental health symptoms in a selected young adult population. The purpose of this study was to investigate if high computer use is a prospective risk factor for developing mental health symptoms in a population-based sample of young adults. METHODS The study group was a(More)
BACKGROUND Prospective associations have been found between high use of information and communication technology (ICT) and reported mental symptoms among young adult university students, but the causal mechanisms are unclear. Our aim was to explore possible explanations for associations between high ICT use and symptoms of depression, sleep disorders, and(More)

METHODS The study focused upon psychological, ergonomic, and physically loading factors and chemical and physical(More)

Yet, few reports strategies workers carry out to improve detrimental work conditions and consequently their health, such as changing jobs. The aim of this study was to examine if adverse(More)
The purpose of this study was to investigate the prevalence of the excess of metabolic level (metabolic demands in work exceeding one-third of the individual's aerobic capacity) of working men and women today and to describe the population whose metabolic level is exceeded. A second aim was to explore how externally assessed metabolic demands match with the(More)
New methods are needed to complement traditional epidemiological methods in the analyses of complex multivariate exposures. Contextual and comprehensive analyses such as multilevel and cluster analyses are particularly suitable for comparisons of women's and men's risk factors for health in working life as well as for guidance in preventive action. Such(More)
AIMS To explore externally assessed demands and control for both women and men in each of the groups of the job demand-control (JDC) model, which itself was based on self-reported data. A specific aim was to better understand why health conditions among women with active jobs were as bad as those among women with high-strain jobs in some earlier studies. (More)
