  1. 1. Bone density, bone geometry and bone development in young men - the importance of pubertal timing and fracture history

    Författare :Anna Darelid; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peak bone mass; bone mineral density; bone development; fracture; young adulthood; men;

    Sammanfattning : Background and objective: Peak bone mass, the maximal bone mass attained in young adulthood, is an important factor of the lifetime risk of developing osteoporosis. The aim of this thesis was to study the development of bone mineral density (BMD) and bone geometry around the time of peak bone mass in men, and also to investigate the association between pubertal timing, fracture history, bone turnover markers and BMD and bone geometry in young men.

  3. 2. Peak Bone Mass, Lifestyle Factors and Birth Weight: A study of 25-year old women

    Författare :Mattias Callréus; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Peak bone mass; normative values; birth weight; physical activity; smoking; bone mineral density; bone mineral content; dual energy X-ray absorptiometry;

    Sammanfattning : Background: Osteoporosis is a common bone disease, which does not give symptoms until the ultimate outcome, the fragility fracture occurs. Regulation of bone mass is controlled by genetic, environmental and nutritional influences. LÄS MER

  4. 3. Bone mineral density in pediatric inflammatory bowel disease

    Författare :Susanne Schmidt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone mineral density; inflammatory bowel disease; children; Crohn s disease; ulcerative colitis; vitamin D; parathyroid hormone; familial resemblance; body composition; growth;

    Sammanfattning : Low bone mineral density (BMD) has been highlighted as a potential problem in children with inflammatory bowel disease (IBD), which is one of the most common chronic childhood diseases in the westernized world. The mechanisms behind reduced BMD in pediatric IBD are still not completely understood, but several factors that influence bone mineralization have been discussed. LÄS MER

  5. 4. The role of physical activity on bone density and bone geometry in men

    Författare :Martin Nilsson; Göteborgs universitet; []
    Nyckelord :bone mineral density; bone geometry; trabecular microarchitecture; physical activity; men;

    Sammanfattning : THE ROLE OF PHYSICAL ACTIVITY ON BONE DENSITY AND BONE GEOMETRY IN MEN Introduction: Several studies indicate that peak bone mass, reached during the third decade in life, is an important determinant of osteoporosis later in life. Physical activity with dynamic loading of the bone is an important determinant of peak bone mass. LÄS MER

  7. 5. Physical activity, bone gain and sustainment of peak bone mass

    Författare :Taru Tervo; Anna Nordström; Peter Nordström; Jon Karlsson; Umeå universitet; []
    Nyckelord :BMD; physical activity; men; athletes; trabecular bone; cortical bone; self-perceived health; MEDICINE; MEDICIN; medicin; Medicine;

    Sammanfattning : Weak and osteoporotic bones are an increasing cause of mortality and painful physical impairment among the elderly, especially in the Western world. Bone mineral density (BMD, g/cm2) accrual during childhood and adolescence is thought to influence an individual’s risk of osteoporosis and the related fractures. LÄS MER
