  1. 1. Methods for measuring physical workload with relevance for musculoskeletal disorders of neck and upper limb

    Författare :Gert-Åke Hansson; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; shoulder; exposure-response relation; exposure; repetitiveness; movements; postures; questionnaire; EMG; electromyography; accelerometer; Goniometer; inclinometer; arm; wrist; hand.; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : Work-related musculoskeletal disorders of the neck and upper limb are a major problem. Women in repetitive manual work is one large affected group. Preventive actions are hampered by the lack of knowledge regarding quantitative exposure-response relations for physical workload. LÄS MER

  3. 2. Prenatal nicotine exposure and effects on the health of the newborn

    Författare :Anna Gunnerbeck; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Maternal smoking is one of the most important preventable risk factors in pregnancy. Whether it is nicotine or combustion products, or possibly both, that cause the adverse effects is not clear. The common substance in snuff and cigarette smoke is nicotine. LÄS MER

  4. 3. Fluoride and health : epidemiological studies of fluoride exposure and hip fracture, myocardial infarction and osteosarcoma

    Författare :Peggy Näsman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of this thesis was to investigate the association between drinking water fluoride exposure and risk of hip fracture, myocardial infarction, and osteosarcoma. Swedish nation- wide population-based registers have been used throughout the thesis. LÄS MER

  5. 4. Environmental and genetic factors in lung cancer : epidemiologocal and biomolecular studies focusing on nonsmokers

    Författare :Fredrik Nyberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Lung cancer; case-control study; smoking misclassification; exposure misclassification; validation; bias; nonsmoker; smoking; environmental tobacco smoke; ETS; diet; biomarker; glutathione S transferase; GSTM1; N-acetyl transferase; NAT2; hypoxanthine-guanine phosphoribosiyl transferase; hprt; DNA; adducts;

    Sammanfattning : Tobacco smoking is the major cause of lung cancer. Other risk factors include exposure to environmental tobacco smoke (ETS), dietary habits and genetic factors. When studying such risk factors, confounding from smoking presents a pervasive methodological problem. LÄS MER

  7. 5. Truncation and missing family links in population-based registers

    Författare :Monica Leu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Left-trunction; Swedish Cancer Registry; MultiGeneration Register; family history; misclassification; simulation; Poplab;

    Sammanfattning : Studies of familial aggregation of disease routinely use linked population registers to construct retrospective cohorts. Although such resources have provided numerous estimates of familial risk, little is known regarding the sensitivity of the estimates to assumed disease models and incompleteness of the data, such as truncation and/or missing family links.
