    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; physical activity; physical fitness; sedentary; questionnaire; validity; self-rated health; sensitivity; specificity; physical activity on prescription; accelerometry; the Ekblom-Bak test; answer modes; movement pattern; health-related quality of life; physical health; Medicin Teknik; Medicine Technology;

    Sammanfattning : Background: Cheap and effective tools for measuring patients’ physical activity (PA) level are needed. The first aim in this thesis was therefore to assess the validity of two PA -questions, and their three associated answer modes, that are used within the Swedish health care system. LÄS MER

  3. 2. Neighborhood environment and physical activity

    Författare :Ulf Eriksson; kardiovaskulär epidemiologi och levnadsvanor Allmänmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; walkability; land use; residential density; physical activity pattern; accelerometer; public health; walking; GIS; physical activity; Neighborhood;

    Sammanfattning : Introduction Insufficient levels of physical activity are one of the top contributors to global mortality, and it is an important public health priority to increase the proportion of physically active people in the population. The interest in environmental determinants of physical activity has been rapidly increasing over the past few years. LÄS MER

  4. 3. Environmental Factors of Importance in Myasthenia Gravis : Emphasis on Physical Activity

    Författare :Elisabet Westerberg; Anna Rostedt Punga; Anne-Marie Landtblom; Chantal Tallaksen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myasthenia Gravis; MG subgroups; Environmental factors; Lifestyle; Physical activity; Exercise; Clinical Neurophysiology; Klinisk neurofysiologi;

    Sammanfattning : Myasthenia Gravis (MG) is an autoimmune disease caused by antibodies directed against proteins at the neuromuscular junction (NMJ). The disturbed neuromuscular transmission induces fatigable weakness in skeletal muscles. LÄS MER

  5. 4. Young today-adult tomorrow! Studies on physical status, physical activity, attitudes, and self-perception in children and adolescents

    Författare :Ann-Christin Sollerhed; Samhällsmedicin; []

    Sammanfattning : The aim was to gain knowledge of young people's physical status and physical activity, and to further the understanding of the role of school physical education in a salutogenic public health perspective. Two studies were performed in southern Sweden. Study 1 was performed in 1996 among 301 adolescents aged 16-19 in upper secondary school. LÄS MER

  7. 5. Solar Wind and Geomagnetic Activity - Predictions Using Neural Networks

    Sammanfattning : This thesis shows how artificial neural networks (ANNs) can be applied to predict geomagnetic activity from solar-wind data. It introduces and summarizes five papers where development of ANN models are reported, and where predictions of geomagnetic activity are discussed. LÄS MER
