Body size, reproductive factors, and XXXX survival.

@entity1 @entity204 @entity0 @entity28
Mortality rates among 838 white female @entity0 @entity1 were examined for relationships to personal characteristics assessed at time of diagnosis. These included weight and body mass index, oral contraceptive use, and prior menstrual and reproductive events. Multivariate analyses were used to determine the importance of these characteristics in predicting @entity204 rates specific for age and extent of disease at time of diagnosis. Weight was associated with poor prognosis among premenopausal @entity1 , but not among postmenopausal @entity1 . Premenopausal @entity1 weighing more than 140 lbs at diagnosis had @entity204 rates 1.7 times those of lighter @entity1 (P = 0.04). This effect was not explained by differences in the distribution of disease stage between the two groups. Body mass index was positively associated with mortality in both premenopausal and postmenopausal @entity1 . In the entire group, the @entity204 rate ratio was 1.4 (P = 0.02) for @entity28 (body mass index greater than 30.4 X 10(-3) lbs/in.2) vs lean @entity1 . Among premenopausal @entity1 , parous @entity1 had higher mortality rates than nulliparous @entity1 ( @entity204 rate ratio = 2.0, P = 0.06). Although the data were sparse, @entity204 rates were higher for @entity1 having a full-term pregnancy within 2 years of diagnosis than for premenopausal @entity1 with earlier pregnancies. Oral contraceptive use, age at menarche, age at first full term birth, and age at menopause were unrelated to mortality.
