   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infancy; Pregnancy; Dietary biomarkers; Cohort; Metabolomics; Breastfeeding; Diet; Allergy; Atopic eczema; Food allergy;

   Sammanfattning : Allergy causes a large burden on society and reduces the quality of life for the individual. The increased allergy incidence over the last decades cannot be explained by genetics. Research has indicated that diet, which is a modifiable factor, might influence the risk of developing allergy. LÄS MER

   Sammanfattning : The overall aim of this thesis is to evaluate the risk for increased morbidity and mortality due to long-term arsenic exposure via drinking water by use of epidemiological and spatial approaches in studies performed in Matlab, Bangladesh. A total of 166,934 individuals aged 4 years and above were screened for skin lesions in 2002-2003. LÄS MER

4. 13. Prospective studies of hormonal and life-style related factors and risk of cancer

   Författare :Sara Wirén; Pär Stattin; Håkan Jonsson; Tanja Stocks; Alicja Wolk; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostate cancer; epidemiology; androgens; risk factors; fatherhood status; dizygotic twins; height; cohort; case-control; prospective; Cancer Epidemiology; cancerepidemiologi;

   Sammanfattning : Background: Androgens are important in prostate cancer development but how circulating levels of androgens affect risk of prostate cancer of different aggressiveness is not clear. Being childless has been associated with a lower risk of prostate cancer, but it is not clear if this association is causal or a result of residual confounding. LÄS MER

5. 14. Diabetes mellitus and risk of prostate cancer - A focus on shared risk factors and survivor bias

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carbohydrates; cohort; competing risk; diabetes mellitus; diet; epidemiology; fiber; gene; gene-environment; lifestyle; prostate cancer; survivor bias; transcription factor 7-like 2; whole-grain; alkylresorcinol metabolites;

   Sammanfattning : Prostate cancer (PCa) is a heterogenous disease including very aggressive lethal tumors to incidentally discovered clinically insignificant tumors. Age, ethnicity, and family history are the only established risk factors. LÄS MER

7. 15. Breast cancer screening with mammography of women 40-49 years in Sweden

   Författare :Barbro Numan Hellquist; Håkan Jonsson; Lennarth Nyström; Nea Malila; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cohort; mortality; breast cancer; mammography screening; risk factors; parity; age at first birth; socio-economic status; overdiagnosis; Oncology; onkologi;

   Sammanfattning : Background The debate regarding the lower age limit for mammography service screening is old and lively; a product in part of the lower breast cancer risk in younger ages as well as the limited data available for studies of the younger age group. Recently the idea of inviting only high risk groups has gained momentum, however high risk might not be equivalent to greater benefit from screening. LÄS MER
