<p>Background: Studies examining diet scores in relation to health outcomes are gaining ground. Thus, control for dietary factors not part of the score, and lifestyle associated with adherence, is required to allow for a causal interpretation of studies on diet scores and health outcomes. <p>Objective: The study objective is to describe and investigate dietary composition, micronutrient density, ...

Background: We aimed to estimate the effect of alcohol consumption on breast cancer risk and to test whether overweight and obesity modifies this association. <p>Methods: We included in the analysis 45,233 women enrolled in the Swedish Women’s Lifestyle and Health study between 1991 and 1992. Participants were followed for occurrence of breast cancer and death until December 2009. Poisson regression ...

Purpose: <br>Sun exposure is associated with risk of several chronic diseases including cancer. The study aim is to investigate whether sun behaviours are related to other lifestyle risk factors of cancer. <br> Methods: <br>We analysed data collected in 2003-2004 by self-completed questionnaire from 34,402 Swedish women aged 40-61 years, who comprised 70% of a cohort of originally recruited from ...

<i>Background</i>: Parity is widely recognized as protective for breast cancer, but breast cancer risk may be increased shortly after childbirth. Whether this risk varies with breastfeeding, family history of breast cancer, or specific tumor subtype has rarely been evaluated.<p> <p><i>Objective</i>: To characterize breast cancer risk in relation to recent childbirth.<p> <p>Design</i> : Pooled ...

Objective:<br> To describe the determinants of 12‐year weight change among middle‐aged women in Sweden. <br>Methods:<br> In 1991/1992, 49,259 women across Sweden were recruited into a cohort. In 2003, 34,402 (73%) completed follow‐up. Lifestyle and health characteristics including weight were collected, and 12‐year weight change and substantial weight gain (≥+5.0 kg) were calculated; association ...

Background: Nulliparity is an endometrial cancer risk factor, but whether or not this association is due to infertility is unclear. Although there are many underlying infertility causes, few studies have assessed risk relations by specific causes.<p> <p>Methods: We conducted a pooled analysis of 8153 cases and 11 713 controls from 2 cohort and 12 case-control studies. All studies provided selfreported ...

Breast cancer is a leading cancer diagnosis among premenopausal women around the world. Unlike rates in postmenopausal women, incidence rates of advanced breast cancer have increased in recent decades for premenopausal women. Progress in identifying contributors to breast cancer risk among premenopausal women has been constrained by the limited numbers of premenopausal breast cancer cases in individual ...

<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, ...

<i>Background</i> - Regular use of aspirin has been associated with a reduced risk of cancer at several sites but the data for endometrial cancer are conflicting. Evidence regarding use of other analgesics is limited.<p><p> <i>Patients and methods</i> - We pooled individual-level data from seven cohort and five case–control studies participating in the Epidemiology of Endometrial Cancer ...
