Early, regular breast-milk pumping may lead to early breast-milk feeding cessation.

ABSTRACT:

Objective

To estimate the effect of early, regular breast-milk pumping on time to breast-milk feeding (BMF) and exclusive BMF cessation, for working and non-working women.

Design

Using the Infant Feeding Practices Survey II (IFPS II), we estimated weighted hazard ratios (HR) for the effect of regular pumping (participant defined) compared with non-regular/not pumping, reported at month 2, on both time to BMF cessation (to 12 months) and time to exclusive BMF cessation (to 6 months), using inverse probability weights to control confounding.

Setting

USA, 2005-2007.

Subjects

BMF (n 1624) and exclusively BMF (n 971) IFPS II participants at month 2.

Results

The weighted HR for time to BMF cessation was 1·62 (95 % CI 1·47, 1·78) and for time to exclusive BMF cessation was 1·14 (95 % CI 1·03, 1·25). Among non-working women, the weighted HR for time to BMF cessation was 2·05 (95 % CI 1·84, 2·28) and for time to exclusive BMF cessation was 1·10 (95 % CI 0·98, 1·22). Among working women, the weighted HR for time to BMF cessation was 0·90 (95 % CI 0·75, 1·07) and for time to exclusive BMF cessation was 1·14 (95 % CI 0·96, 1·36).

Conclusions

Overall, regular pumpers were more likely to stop BMF and exclusive BMF than non-regular/non-pumpers. Non-working regular pumpers were more likely than non-regular/non-pumpers to stop BMF. There was no effect among working women. Early, regular pumpers may need specialized support to maintain BMF.

Project description:In spite of high rates of initiating breast milk feeding (BMF) among preterm infants, a significant rate of discontinuation occurs shortly after discharge. To investigate the effect of mode (direct feeding at the breast vs. expressing) and exclusivity (breast milk combined with formula vs. breast milk only) as well as maternal perceptions on the duration of BMF among preterm infants. The study included mothers whose infants were born before 32 weeks gestation, between January 2012 and August 2015 at Sheba Medical Center (SMC). Perinatal data were collected retrospectively from infants' computerized charts. Mothers were approached >12 months postpartum and were asked to complete a questionnaire. Those who agreed to participate were asked (during their visit to the follow-up clinic or by phone or mail) to complete a questionnaire regarding mode and duration of BMF as well as reasons for its discontinuation. Mothers were also asked about their pre-partum intentions to feed directly at the breast. Out of 162 eligible mothers, 131 (80.8%) initiated BMF during their intensive care unit (ICU) hospitalization. Of these, 66 (50.3%) discontinued BMF earlier than six months postpartum. BMF ≥ 6 months was significantly associated with direct feeding at the breast, duration of exclusive BMF, and singleton birth. Regression analysis revealed that direct feeding at the breast (any or only) and duration of BMF exclusivity were the only significant variables associated with BMF duration (Odds ratio (OR) 5.5 and 95% confidence interval (CI) 2.00-15.37; OR 1.5 and 95% CI 1.25-1.88, respectively). Milk supply (inadequate or nonexistent) was the most commonly reported cause for BMF discontinuation <6 months. Direct feeding at the breast was significantly associated with BMF duration and was more common among singletons. Direct feeding at the breast and duration of exclusive BMF are associated with duration of BMF among infants born <32 weeks of gestational age (GA). These findings suggest that targeting these two factors may play a key role in prolonging BMF duration among preterm infants.

Project description:IntroductionNational and international organizations have done an excellent job of advocating and promoting breast feeding for all mothers. This study assessed to what extent an intervention increased delivery of cessation assistance to breast-feeding mothers who smoke.MethodsData were collected between April and October 2015 in five US states as part of a cluster randomized controlled trial in 10 pediatric practices. Practices were randomized to the Clinical Effort Against Secondhand Smoke Exposure (CEASE) intervention or usual care control arms. Mothers were asked about their smoking status and breast-feeding history during a screening interview upon exiting the practice and eligible mothers who agreed to participate in an enrollment interview were asked if they received smoking cessation assistance during their child's visit. Mothers with a child 1 year old and younger were included in the analyses.ResultsCurrent breast feeding was associated with a reduced likelihood of current smoking (adjusted odds ratio [aOR] = 0.38, 95% confidence interval [95% CI] = 0.25 to 0.57) and a greater likelihood of quitting smoking (aOR = 2.33, 95% CI = 1.29 to 4.21) after controlling for known confounders. Mothers who concurrently smoked and breast-fed were more likely to be asked about smoking (66.7% vs. 28.6%, p = .01), advised to quit (61.1% vs. 21.4%, p < .01), prescribed nicotine replacement therapy (50.0% vs. 0%, p < .001), and enrolled into the quitline (27.8% vs. 0%, p < .01) at CEASE practices compared to control practices.ConclusionBreast-feeding mothers were less likely to be current smokers and more likely to have recently quit smoking. Among mothers who continue to smoke and breast feed, the CEASE intervention enhances delivery of smoking cessation assistance.ImplicationsBreast feeding and eliminating infants' exposure to tobacco smoke are important protective factors for serious pediatric health risks including sudden infant death. This study shows that breast feeding was positively associated with desirable tobacco control outcomes, specifically that breast feeding was associated with a lower likelihood of smoking among ever smokers and a greater likelihood of recently quitting smoking. This is also the first study to look specifically at delivery of smoking cessation assistance to breast-feeding mothers seen at pediatric offices and demonstrates the effectiveness of delivering evidence-based smoking cessation assistance to them in this context.Trial registrationwww.ClinicalTrials.gov (identifier NCT01882348).
