Different measures of smoking exposure and mammographic density in postmenopausal Norwegian women : a cross-sectional study
(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 ... -

Use of hormonal contraceptives and occurrence of pregnancy-related pelvic pain. A prospective cohort study in Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2004-06-22)Background: Pregnancy-related pelvic pain is a common condition, and use of hormonal contraceptives before pregnancy has been proposed as a risk factor. We used data from a sub-sample of women participating in the "Norwegian Women and Cancer study" (NOWAC) to assess the association between hormonal contraceptive use and pelvic pain in pregnancy. 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
(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
(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 ... -
Cancer incidence in Arkhangelskaja Oblast in northwestern Russia. The Arkhangelsk Cancer Registry
(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 ... -
Percentage density, Wolfe's and Tabár's mammographic patterns. Agreement and association with risk factors for breast cancer
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005-08-25)Introduction: The purpose of this report was to classify mammograms according to four methods and to examine their agreement and their relationship to selected risk factors for breast cancer. 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 ... -
TP53 mutations in ovarian carcinomas from sporadic cases and carriers of two distinct BRCA1 founder mutations. Relation to age at diagnosis and survival
(Journal article; Tidsskriftartikkel; Peer reviewed, 2005-10-17)Background: Ovarian carcinomas from 30 BRCA1 germ-line carriers of two distinct high penetrant founder mutations, 20 carrying the 1675delA and 10 the 1135insA, and 100 sporadic cases were characterized for somatic mutations in the TP53 gene. We analyzed differences in relation to BRCA1 germline status, TP53 status, survival and age at diagnosis, as previous studies have not been conclusive. Methods: ... -
Test-retest reproducibility of a food frequency questionnaire (FFQ) and estimated effects on disease risk in the Norwegian Women and Cancer Study (NOWAC)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-01-31)Background: The Norwegian Women and Cancer Study (NOWAC) is a national population-based cohort study with 102 443 women enrolled at age 30–70 y from 1991 to 1997. The present study was a methodological sub-study to assess the test-retest reproducibility of the NOWAC food frequency questionnaire (FFQ), and to study how measurement errors in the data can affect estimates of disease risk. Methods: A ... -
"When patients have cancer, they stop seeing me". The role of the general practitioner in early follow-up of patients with cancer. A qualitative study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-03-21)Background The role of the general practitioner (GP) in cancer follow-up is poorly defined. We wanted to describe and analyse the role of the GP during initial follow-up of patients with recently treated cancer, from the perspective of patients, their relatives and their GPs. Methods One focus group interview with six GPs from the city of Bodø and individual interviews with 17 GPs from the ... -
Acute psychiatric admissions from an out-of-hours Casualty Clinic. How do referring doctors and admitting specialists agree?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-03-29)Background: Over the last decades there has been an increasing pressure on the acute psychiatric wards in Norway. The major contributor to psychiatric acute admissions at the University Hospital of North Norway in the city of Tromsø in 2001 was the GP-based Tromsø Casualty Clinic, only open out-of-hours. We explored all acute psychiatric referrals from Tromsø Casualty Clinic in 2001. The purpose ... -
Regression analysis with categorized regression calibrated exposure. Some interesting findings
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-07-04)Background: Regression calibration as a method for handling measurement error is becoming increasingly well-known and used in epidemiologic research. However, the standard version of the method is not appropriate for exposure analyzed on a categorical (e.g. quintile) scale, an approach commonly used in epidemiologic studies. A tempting solution could then be to use the predicted continuous ... -
Plasma levels of leptin and mammographic density among postmenopausal women. A cross-sectional study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2006-09-29)Introduction Obesity has been linked to increased risk of breast cancer in postmenopausal women. Increased peripheral production of estrogens has been regarded as the main cause for this association, but other features of increased body fat mass may also play a part. Leptin is a protein produced mainly by adipose tissue and may represent a growth factor in cancer. We examined the association ... -
