    • Local public health physicians in Norway from 1994 to 2002 : workload, work content, and interaction : a story of everyday life in primary health care 

      Pettersen, Betty Johanne (Doctoral thesis; Doktorgradsavhandling, 2008-03-07)
      Avhandlingens tema er utviklingen innenfor lokal samfunnsmedisinsk legetjeneste fra 1994 til 2002. Desentraliserings- og liberaliseringsreformer i primærhelsetjenesten, endringer i helseforhold og etterspørsel etter helsetjenester endret arbeidsarenaen for samfunnsmedisinerne, og gav økonomiske, organisatoriske og faglige utfordringer. Avhandlingen er basert på tre tverrsnittsundersøkelser, gjennom ...

      Sakshaug, Solveig; Hartz, Ingeborg; Furu, Kari; Skurtveit, Svetlana; Engeland, Anders; Eggen, Anne Elise; Njølstad, Inger (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-12-05)
      Background: A previous study has shown that variations in threshold and intensity (lipid goal attainment) of statins for primary prevention contribute to regional differences in overall consumption of statins in Norway. Our objective was to explore how differences in prevalences of use, dosing characteristics, choice of statin and continuity of therapy in individual patients adds new information ...
    • Assessing medical students' attitudes towards learning communication skills : which components of attitudes do we measure? 

      Gude, Tore; Anvik, Tor; Bærheim, Anders; Risberg, Terje; Fasmer, Ole B.; Hjortdahl, Per; Holen, Are; Vaglum, Per (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-03-30)
      Background: The Communication Skills Attitudes Scale (CSAS) created by Rees, Sheard and Davies and published in 2002 has been a widely used instrument for measuring medical students' attitudes towards learning communication skills. Earlier studies have shown that the CSAS mainly tests two dimensions of attitudes towards communication; positive attitudes (PAS) and negative attitudes (NAS). The ...

      Background: Several countries are discussing new legislation on the ban of smoking in public places, and on the acceptable levels of traffic-related air pollutants. It is therefore useful to estimate the burden of disease associated with indoor and outdoor air pollution. Methods: We have estimated exposure to Environmental Tobacco Smoke (ETS) and to air pollution in never smokers and ex-smokers ...
    • Curriculum factors influencing knowledge of communication skills among medical students 

      Bærheim, Anders; Anvik, Tor; Risberg, Terje; Hjortdahl, Per; Holen, Are; Fasmer, Ole Bernt; Grimstad, Hilde; Gude, Tore; Vaglum, Per (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-10-10)
      Background: Communication training builds on the assumption that understanding of the concepts related to professional communication facilitates the training. We know little about whether students' knowledge of clinical communication skills is affected by their attendance of communication training courses, or to what degree other elements of the clinical training or curriculum design also play a ...
    • Different measures of smoking exposure and mammographic density in postmenopausal Norwegian women : a cross-sectional study 

      Bremnes, Yngve; Bjurstam, Nils; Ursin, Giske; Gram, Inger Torhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2007-10-26)
      Background: Recent cohort studies have suggested an increased risk of breast cancer with long duration of smoking, and with smoking initiation before first birth. Cigarette smoking may have both carcinogenic effects and antiestrogenic effects on the breast tissue. We decided to examine the relationship between different measures of smoking exposure and mammographic density. Methods: Lifetime ...

      Background: In this study, we wanted to investigate the relationship between background variables, communication skills, and the bio-psychosocial content of a medical consultation in a general practice setting with a standardized patient. Methods: Final-year medical school students (N = 111) carried out a consultation with an actor playing the role of a patient with a specific somatic complaint, ...
    • Qualitative research methods in complementary and alternative treatment 

      Rieper, Olaf; Launsø, Laila (Forskningsrapport; Research report, 2007-01)
      Denne rapport giver en introduction til kvalitative forskningsmetoder, der er velegnede til forskning i komplementær og alternativ behandling. Kvalitative og kvantitative metoder producerer meget forskellige former for kundskaber, som er rettet mod forskellige brugssammenhænge og formål. Vi starter med at forholde os til evidens-baseret viden og beskriver epistemologiske baggrunde for at vælge ...

Methods: From a sub-group of 2078 parous women ...
    • Length of sick leave – Why not ask the sick-listed? Sick-listed individuals predict their length of sick leave more accurately than professionals 

      Johnsen, Roar; Fleten, Nils; Førde, Olav Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2004-10-12)
      Background: The knowledge of factors accurately predicting the long lasting sick leaves is sparse, but information on medical condition is believed to be necessary to identify persons at risk. Based on the current practice, with identifying sick-listed individuals at risk of long-lasting sick leaves, the objectives of this study were to inquire the diagnostic accuracy of length of sick leaves ...
    • Reliability of sickness certificates in detecting potential sick leave reduction by modifying working conditions. A clinical epidemiology study 

      Johnsen, Roar; Fleten, Nils; Østrem, Bente Skipenes (Journal article; Tidsskriftartikkel; Peer reviewed, 2004-03-25)
      Background: Medical sickness certificates are generally the main source for information when scrutinizing the need for aimed intervention strategies to avoid or reduce the individual and community side effects of sick leave. This study explored the value of medical sickness certificates related to daily work in Norwegian National Insurance Offices to identify sick-listed persons, where modified ...

      Lebedintseva, Jelena A.; Vaktskjold, Arild; Lund, Eiliv; Korotov, Dmitrij S.; Tkatsjov, Anatolij V.; Podjakova, Tatjana S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2005-07-19)
      Background: Data concerning incidence and prevalence of cancer in the different regions of Russia have traditionally not been provided on a basis that facilitated comparison with data from countries in western parts of Europe. The oncological hospital in Arkhangelsk, in co-operation with Universitetet i Tromsø (Norway), has established a population based cancer registry for Arkhangelskaja Oblast ...

Method: Mammograms and epidemiological data were collected from 987 women, aged 55 to 71 years, attending the Norwegian Breast Cancer Screening Program. Two readers each classified the mammograms according ...
