Purpose Previous studies have shown that low levels of 25-hydroxyvitamin D (25(OH)D) are associated with a poorer breast cancer survival. The relationship between vitamin D status and breast cancer outcomes is however still debated. The aim of the present study was to investigate the association between 25(OH)D blood levels measured at time of diagnosis and event-free survival (EFS) and overall survival (OS) in a large cohort of patients with early-stage primary invasive breast cancer.

Objective: Waist circumference, BMI and hip circumference are differentially associated with mortality. We investigated the potential influence of selected lifestyle aspects such as smoking, alcohol intake, sports activity and education. Method: The Danish prospective study ‘Diet, Cancer and Health’ recruited 27,179 men and 29,875 women from 1993 to 1997. Cox regression models were used to estimate mortality rate ratios. Results: Adjustment for smoking habits attenuated the associations between ...

kg/m 2 among never users of HRT was 0.98 (95% confi- dence interval, 0.93 to 1.03) for BFM index and 1.12 (95% confidence interval, 1.00 to 1.26) for FFM index after mutual adjustment. Discussion: The finding for BMI was in accordance with previous findings. Our results indicate that the FFM com- ponent of BMI may play a role for development of breast cancer among never users of HRT.

We investigated the agreement between 1) self-reported and technician-measured waist circumference at the level of the umbilicus, 2) circumference measured at the level of the umbilicus and halfway between the lower rib and the iliac crest (the natural waist), and 3) self-reported circumference at the level of the umbilicus and technician-measured circumference at the natural waist. At follow-up in the Danish Diet, Cancer and Health study, we recruited 176 men and 240 women for a validation stud...

The evidence for anthropometric factors influencing breast cancer risk is accumulating, but uncertainties remain concerning the role of fat distribution and potential effect modifiers. We used data from 73,542 premenopausal and 103,344 postmenopausal women from 9 European countries, taking part in the EPIC study. RRs from Cox regression models were calculated, using measured height, weight, BMI and waist and hip circumferences; categorized by cohort wide quintiles; and expressed as continuous va...

Objective: To investigate whether the association between BMI and all-cause mortality could be disentangled into opposite effects of body fat and fat-free mass (FFM). Research Methods and Procedures: All-cause mortality was studied in the Danish follow-up study “Diet, Cancer and Health” with 27, 178 men and 29, 875 women 50 to 64 years old recruited from 1993 to 1997. By the end of year 2001, the median follow-up was 5.8 years, and 1851 had died. Body composition was assessed by bioelectrical im...
