<p><i>Background</i>: Cigarette smoking is associated with earlier menopause, but the impact of being a former smoker and any dose-response relationships on the degree of smoking and age at menopause have been less clear. If the toxic impact of cigarette smoking on ovarian function is irreversible, we hypothesized that even former smokers might experience earlier menopause, and variations in intensity, ...

Background - Indicators of socioeconomic position (SEP) and health behaviours (HB) are widely used predictors of health variations. Their relative importance is hard to establish, because HB takes a mediating role in the link between SEP and health. We aim to provide new knowledge on how SEP and HB are related to health and wellbeing.<p> <p>Methods - The analysis considered 14,713 Norwegians aged ...

Objective Although metabolic profiles have been associated with chronic disease risk, lack of temporal stability of metabolite levels could limit their use in epidemiological investigations. The present study aims to evaluate the reliability over a two-year period of 158 metabolites and compare reliability over time in fasting and non-fasting serum samples. <p>Methods Metabolites were measured ...

Given the higher suicide rates among the adult population in the northernmost part of Norway and some unfavourable psychosocial outcomes associated with the Laestadian revival movement in this region, it is reasonable to investigate the relationship between religiosity/spirituality and suicidal behaviour in this context. This study used cross-sectional data from the population-based SAMINOR 2 ...

Nordic Nutrition Recommendations recommend reducing red and processed meat and increasing fish consumption, but the impact of this replacement on mortality is understudied. This study investigated the replacement of red and processed meat with fish in relation to mortality. Of 83 304 women in the Norwegian Women and Cancer Study (NOWAC) study, 9420 died during a median of 21·0 years of follow-up. ...

Background: Previous studies of the reproducibility of self-reported age at menarche have been limited because of small study samples, short follow-up and the limited age span of the women included. Methods: The present study assessed the reproducibility of age at menarche in 6731 women with a wide variation of age when giving the information about age at menarche. The women reported age at ...

Background: Reproductive factors influence the risk of developing epithelial ovarian cancer (EOC), but little is known about their association with survival. We tested whether prediagnostic reproductive factors influenced EOC-specific survival among 1025 invasive EOC cases identified in the European Prospective Investigation into Cancer and Nutrition (EPIC) study, which included 521 330 total ...

Background: Reproductive events are associated with important physiologic changes, yet little is known about how reproductive factors influence long-term health in women. Our objective was to assess the relation of reproductive characteristics with all-cause and cause-specific mortality risk. <p>Methods: The analysis was performed within the European Investigation into Cancer and Nutrition ...

Årsrapport for 2013 fra Register for Eksepsjonelle Sykdomsforløp (RESF).

Social differences in health and illness are well-documented in Denmark. However, very little is known about how health practices manifest in the everyday lives of different social classes. We propose acts of resistance and formation of health subjectivities as helpful concepts to develop our understanding of how dominant health discourses are appropriated by different social classes and transformed ...
