1. Neighborhood environment and physical activity
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
2. Physical activity, bone density, and fragility fractures in women
Sammanfattning : Scandinavia has among the highest incidence of fragility fractures in the world. The reasons for this are unknown, but might involve differences in genetic and/or environmental factors, such as sunlight exposure and levels of physical activity. LÄS MER
3. Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods
Sammanfattning : Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. LÄS MER
4. Bone mass and physical activity
Sammanfattning : Abstract Weak and osteoporotic bones in old age are an increasing cause of mortality and painful physical impairment of the elderly, especially in the western world. Bone mineral accrual during childhood and adolescence is thought to play a vital role in preventing osteoporosis. LÄS MER
5. Physical activity and regional bone mass
Sammanfattning : This thesis considers the effect of physical activity on bone mass in weight-loaded and unloaded regions of the skeleton. Bone mass was measured by Dual X-ray Absorptiometry (DXA) and by Quantitative Ultrasound (QUS). LÄS MER
