Ingrid Bergström group
Bone metabolism, physical activity, hormones and D-vitamin
Ingrid Bergström became specialist in Obstetrics and Gynecology 1995. She defended her thesis titled "Effects of gonadal hormone deficiency on bone mineral density. Can physical activity increase bone mineral density in women?" in 2006.
She is now doing preclinical and clinical translational research in collaboration with associate professor Sara Windahl Department of Medicine, Endocrine division, Sahlgrenska Academy, University of Gothenburg and professor Göran Andersson, Division of Pathology, Karolinska Institutet, Stockholm concerning the effect of strain on the bone metabolism in different hormonal conditions. Her clinical work since 2001 concerns Osteoporosis, Bone disorders and Gynecological Endocrinology.
Since 2007 she is the principle investigator of the project: Vitamin D deficiency in immigrant pregnant women and its effects on bone metabolism and pain. The project is now continuing as a treatment study.

Vitamin D treatment in immigrant women
Reduced physical activity and hormonal changes are important factors for developing osteoporosis in patients at high risk for this clinically important condition.
The overall aim of this project is to characterize bone metabolism in order to understand how physical activity may prevent osteoporosis and to investigate the effects of vitamin D treatment in immigrant women with vitamin D deficiency. The current method (DEXA) is insufficient to measure the effect of load on bone strength. Other factors such as the macro- and micro-architecture and collagen content and its characteristics affect the strength. We have extensive experience in training effects on bone markers and bone mineral density (BMD) measured by DEXA.
With the help of grants from the Wallenberg Foundation, we have established a method for analysis of bone structure by quantitative computed tomography (pQCT). We have also established a bone biopsy method and will evaluate the effects on micro-architecture, collagen and on the osteocyte. Our studies are performed with a truly translational approach by combining clinical human research with basic mechanistic studies in in vivo model systems.
Lack of sunlight increases the risk of vitamin D deficiency. Our study on 68 pregnant immigrant women shows that 78% have deficiency, and indicate that this is associated with pain. We are analyzing the effects of vitamin D treatment on bone structure, but also on the pain, muscle strength and balance of immigrant women with vitamin D deficiency.
