“…History of breastfeeding significantly decreased the risk of mortality among those who survived 10 years or more yet was not significantly associated with short-term survival. Breastfeeding may significantly impact long-term survival, as it is a protective risk factor for overall mortality in the general population [ 26 ]. Smoking history and obesity increased the risk of mortality among long-term survivors but had no impact on short-term survival.…”

Tumor- and treatment-related factors are established predictors of ovarian cancer survival. New studies suggest a differential impact of exposures on ovarian cancer survival trajectories (i.e., rapidly fatal to long-term disease). This study examined the impact of pre-diagnostic risk factors on short- and long-term ovarian cancer survival trajectories in the Canadian context. This population-based longitudinal observational study included women diagnosed with invasive epithelial ovarian cancer from 1995 to 2004 in Ontario. Data were obtained from medical records, interviews, and the provincial cancer registry. Extended Cox proportional hazard models estimated the association between risk factors and all-cause and ovarian cancer-specific mortality by survival time intervals (<3 years (i.e., short-term survival), 3 to <6 years, 6 to <10 years, and ≥10 years (i.e., long-term survival)). Among 1421 women, histology, stage, and residual disease were the most important predictors of all-cause mortality in all survival trajectories, particularly for short-term survival. Reproductive and lifestyle factors did not strongly impact short-term overall survival but were associated with long-term overall survival. As such, among long-term survivors, history of breastfeeding significantly decreased the risk of all-cause mortality (HR 0.65; 95% CI 0.46, 0.93; p < 0.05), whereas smoking history (HR 1.75; 95% CI 1.27, 2.40; p < 0.05) and obesity (HR 1.81; 95% CI 1.24, 2.65; p < 0.05) significantly increased the risk of all-cause mortality. The findings were consistent with ovarian cancer-specific mortality. These findings suggest that pre-diagnostic exposures differentially influence survival time following a diagnosis of ovarian cancer.

Objective To explore associations between early life physical and sexual abuse and subsequent risk of premature mortality (death before age 70 years). Design Prospective cohort study. Setting The Nurses’ Health Study II (2001-19). Participants 67 726 female nurses aged 37-54 years when completing a violence victimization questionnaire in 2001. Main outcome measures Hazard ratios and 95% confidence intervals for total and cause specific premature mortality by childhood or adolescent physical and sexual abuse, estimated by multivariable Cox proportional hazard models. Results 2410 premature deaths were identified over 18 years of follow-up. Nurses who experienced severe physical abuse or forced sexual activity in childhood and adolescence had a higher crude premature mortality rate than nurses without such abuse in childhood or adolescence (3.15 v 1.83 and 4.00 v 1.90 per 1000 person years, respectively). The corresponding age adjusted hazard ratios for premature deaths were 1.65 (95% confidence interval 1.45 to 1.87) and 2.04 (1.71 to 2.44), respectively, which were materially unchanged after further adjusting for personal characteristics and early life socioeconomic status (1.53, 1.35 to 1.74, and 1.80, 1.50 to 2.15, respectively). Cause specific analyses indicated that severe physical abuse was associated with a greater risk of mortality due to external causes of injury and poisoning (multivariable adjusted hazard ratio 2.81, 95% confidence interval 1.62 to 4.89), suicide (3.05, 1.41 to 6.60), and diseases of the digestive system (2.40, 1.01 to 5.68). Forced sexual activity as a child and adolescent was associated with greater risk of mortality due to cardiovascular disease (2.48, 1.37 to 4.46), external injury or poisoning (3.25, 1.53 to 6.91), suicide (4.30, 1.74 to 10.61), respiratory disease (3.74, 1.40 to 9.99), and diseases of the digestive system (4.83, 1.77 to 13.21). The association of sexual abuse with premature mortality was stronger among women who smoked or had higher levels of anxiety during adulthood. Smoking, low physical activity, anxiety, and depression each explained 3.9-22.4% of the association between early life abuse and premature mortality. Conclusion Early life physical and sexual abuse could be associated with a greater risk of adult premature mortality.

“…Infants breastfed for at least 7 months have a reduced risk of respiratory infections and hospitalizations due to any infection (Bartick et al, 2017;Christensen et al, 2020). In a large US study, the lifetime total breastfeeding duration was associated with a lower subsequent risk of all-cause mortality in a non-linear manner, suggesting that a longer lifetime breastfeeding duration have a modestly lower risk of mortality (Wang et al, 2022). Despite the bene ts of extended breastfeeding duration, the rate of mothers who breastfed (any amount) at 3 months in 2019 was 69.1% (CDC, 2022b).…”

Background There is limited research on the interaction between pre-pregnancy behaviours of folic acid intake and smoking, and breastfeeding duration. Pre-pregnancy folic acid intake and breastfeeding are health promoting behaviours benefiting mothers and infants, whereas smoking has adverse effects. This study aims to examine the association between maternal pre-pregnancy folic acid intake frequency and 3-month breastfeeding with further examination of the moderating influence of pre-pregnancy smoking. Methods A secondary data analysis was conducted using data from the 2016–2019 Pregnancy Risk Assessment and Monitoring System (n = 70,947 postpartum mothers). Results Overall, 28.5% did not breastfeed at least 3 months, 42.0% reported not taking folic acid pre-pregnancy, and 13.2% reported pre-pregnancy smoking. In the multivariable model, there was a significant interaction between pre-pregnancy smoking and folic acid intake on 3-month breastfeeding. For the subgroup of non-smokers, the odds of breastfeeding for at least 3 months were significantly higher among mothers who took folic acid (1 to 3 times per week, aOR 1.21, p = 0.001; 4 to 6 times per week aOR 1.74, p < 0.001; and daily aOR 1.25, p < 0.001; p-trend < 0.001) compared to those who did not take folic acid. Conclusions In the population-based study, pre-pregnancy folic acid intake was associated with higher odds of breastfeeding at least 3 months among women who did not smoke pre-pregnancy. Nurse-midwives and other healthcare professionals caring for women of childbearing age should encourage a positive health-promoting lifestyle before pregnancy, including folic acid intake and smoking abstinence, which may contribute to positive health behaviour of breastfeeding.
