Pre-diagnostic copper and zinc biomarkers and colorectal cancer risk in the European Prospective Investigation into Cancer and Nutrition cohort
(Journal article; Tidsskriftartikkel; Peer reviewed; Preprint; Manuskript, 2017-07-01)
Adequate intake of copper and zinc, two essential micronutrients, are important for antioxidant functions. Their imbalance may have implications for development of diseases like colorectal cancer (CRC), where oxidative stress is thought to be etiologically involved. As evidence from prospective epidemiologic studies is lacking, we conducted a case-control study nested within the European Prospective ...
Global, regional, and national incidence, prevalence, and years lived with disability for 328 diseases and injuries for 195 countries, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-09-14)
BACKGROUND: As mortality rates decline, life expectancy increases, and populations age, non-fatal outcomes of diseases and injuries are becoming a larger component of the global burden of disease. The Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) provides a comprehensive assessment of prevalence, incidence, and years lived with disability (YLDs) for 328 causes in 195 ...
Challenges in assessing the sunscreen-melanoma association
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-16)
Whether sunscreen use affects melanoma risk has been widely studied with contradictory results. To answer this question we performed a systematic review of all published studies, accounting for sources of heterogeneity and bias. We searched for original articles investigating the sunscreen‐melanoma association in humans to February 28, 2018. We then used random‐effects meta‐analysis to combine ...
Lifetime number of years of menstruation as a risk index for postmenopausal endometrial cancer in the Norwegian Women and Cancer Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-21)
<p><i>Introduction</i>: Lifetime number of years of menstruation (LNYM) reflects a woman's cumulative exposure to endogenous estrogen and can be used as a measure of the combined effect of reproductive factors related to endometrial cancer (EC) risk.</p>
<p><i>Material and methods</i>: We aimed to study the association between LNYM and EC risk among postmenopausal women and calculate the population ...
Haem iron intake and risk of lung cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-18)
<p><i>Background</i>: Epidemiological studies suggest that haem iron, which is found predominantly in red meat and increases endogenous formation of carcinogenic N-nitroso compounds, may be positively associated with lung cancer. The objective was to examine the relationship between haem iron intake and lung cancer risk using detailed smoking history data and serum cotinine to control for potential ...
Risk of lung cancer and physical activity by smoking status and body mass index, the Norwegian Women and Cancer Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-01)
We aimed to investigate physical activity (PA) and risk of different histological subtypes of lung cancer according to smoking status and body mass index using repeated measurements in a large cohort of women in Norway. The study sample for the multiple imputation analyses consisted of 86,499 and for the complete-case analysis 80,802 women. Repeated measurements of PA level, smoking habits, weight, ...
Nutritional quality of food as represented by the FSAm-NPS nutrient profiling system underlying the Nutri-Score label and cancer risk in Europe: Results from the EPIC prospective cohort study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-18)
<p><i>Background - </i>Helping consumers make healthier food choices is a key issue for the prevention of cancer and other diseases. In many countries, political authorities are considering the implementation of a simplified labelling system to reflect the nutritional quality of food products. The Nutri-Score, a five-colour nutrition label, is derived from the Nutrient Profiling System of the British ...
Methodological issues in a prospective study on plasma concentrations of persistent organic pollutants and pancreatic cancer risk within the EPIC cohort
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-23)
<i>Background</i> - The use of biomarkers of environmental exposure to explore new risk factors for pancreatic cancer presents clinical, logistic, and methodological challenges that are also relevant in research on other complex diseases.<p>
<p><i>Objectives</i> - First, to summarize the main design features of a prospective case-control study –nested within the European Prospective Investigation ...
Attendance to cervical cancer screening among Roma and non-Roma women living in North-Western region of Romania
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-27)
<p><i>Objectives</i>: Romania has Europe’s highest incidence and mortality rates of cervical cancer. Participation in the national cervical cancer-screening programme is low, especially among minority Roma women.</p>
<p><i>Methods</i>: We conducted a cross-sectional study, using a structured questionnaire aiming to quantify reasons for screening attendance among women in North-Western region of ...
Adipokines and inflammation markers and risk of differentiated thyroid carcinoma: The EPIC study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-23)
Other than the influence of ionizing radiation and benign thyroid disease, little is known about the risk factors for differentiated thyroid cancer (TC) which is an increasing common cancer worldwide. Consistent evidence shows that body mass is positively associated with TC risk. As excess weight is a state of chronic inflammation, we investigated the relationship between concentrations of leptin, ...
