OBJECTIVE Large body size has been associated with decreased risk of breast cancer in premenopausal women but with increased risk in postmenopausal women. Limited information is available about African-American women and differences by estrogen and progesterone receptor status. METHODS We analyzed data from the Women's Contraceptive and Reproductive(More)
Established dietary predictors of plasma total homocysteine (tHcy) include folate, riboflavin, and vitamins B6 and B12, while information is scarce regarding other dietary components. The aim of this study was to examine the relation between a variety of food groups, food items and nutrients, and plasma tHcy in a large population-based study. The study(More)
BACKGROUND Limited information is available on the association between vitamin B-12 status and intake from different dietary sources. OBJECTIVE We investigated the relation of dietary intake of different food items with plasma vitamin B-12 concentrations in the general population. DESIGN A cross-sectional, population-based study of 5937 subjects in 2(More)
Alcohol intake has been consistently associated with breast cancer risk, but the importance of timing of intake and the impact of beverage type are unclear. We evaluated whether early, lifetime or recent alcohol intake was associated with breast cancer risk, and whether risk varied by type of alcoholic drinks in 1,728 newly diagnosed population-based breast(More)
We have investigated the effect of fish oil supplementation on the association between serum non-esterified fatty acid (NEFA) pattern and atherosclerotic activity. We studied correlations between serum non-esterified very long-chain eicosapentaenoic (EPA), docosahexaenoic acid (DHA) and arachidonic acid (AA) and biochemical markers of endothelial activation(More)
BACKGROUND Dietary factors and very-long-chain n-3 polyunsaturated fatty acids (n-3 PUFAs) may influence the atherothrombotic process. Elevated concentrations of circulating cell adhesion molecules, thrombomodulin (TM), von Willebrand factor (vWF), and tissue-type plasminogen activator antigen (tPAag) are related to atherothrombotic cardiovascular disease.(More)
BACKGROUND The intake of n-3 (formerly called omega-3) fatty acids (FAs) may be inversely associated with plasma total homocysteine (tHcy) concentrations, but the epidemiologic data are sparse. OBJECTIVE We examined the association between dietary fat and tHcy in a Norwegian population. DESIGN A cross-sectional, population-based study of 5917 subjects(More)
Fatty acid metabolism is altered in colorectal cancer (CRC). We aimed to investigate incorporation of dietary n-6 and n-3 polyunsaturated fatty acids (PUFAs) into plasma phospholipids (PLs), tumour tissue, and normal mucosa in young CRC patients. We also aimed to study differences in PUFA composition between tumour and normal mucosa, and PUFA status(More)
AIM To investigate the association between adherence to health recommendations and detection of advanced colorectal neoplasia (ACN) in colorectal cancer (CRC) screening. METHODS A total of 14832 women and men were invited to CRC screening, 6959 in the fecal immunochemical test arm and 7873 in the flexible sigmoidoscopy arm. These were also sent a(More)
When planning national screening programs, it is important to investigate potential changes in health behavior initiated by the screening. Knowledge of the consequences of different colorectal cancer (CRC) screening modalities for health behavior is limited. We aimed to investigate differences in 1-year health behavior changes after testing negative in CRC(More)
