Relationship between prenatal infant feeding intention and initiation and duration of breastfeeding: a cohort study

AIM: To report the relationship between maternal prenatal intention to breastfeed and the actual initiation and duration of breastfeeding. METHODS: Pregnant women resident within Avon, UK, expected to give birth between 1 April 1991 and 31 December 1992 were recruited in a longitudinal cohort study. Main outcome measures included maternal infant feeding intention (breastfeed, breast and bottle feed, bottle feed, or uncertain) at 32 wk of pregnancy: intention in the first week, intention for the rest of the first month and intention in months 2 to 4; initiation and duration of breastfeeding up to six months. RESULTS: Data were available on 10,548 women. Prenatal intention to breastfeed had an influence on both initiation and duration of breastfeeding. Of the women intending to bottle feed from birth, only 3.4% initiated breastfeeding compared with 96.6% of women planning to breastfeed for at least four months. At six months postpartum, the mean duration of breastfeeding for women intending to breastfeed for at least five months was 4.4 mo (95% CI 4.3, 4.4), compared with 2.5 mo (95% CI 2.4, 2.6) for women with a prenatal intention to breastfeed for only one month. Logistic regression, using intended duration as the only explanatory variable, correctly predicted 91.4% of breastfeeding initiation and 72.2% of infant feeding at six months. CONCLUSIONS: This large population-based study confirms the strength of the relationship between maternal prenatal intention to breastfeed and both breastfeeding initiation and duration. Maternal intention was a stronger predictor than the standard demographic factors combined. This should be taken into account in future research, and trials should be undertaken to establish whether interventions could alter maternal intention and thereby increase rates of breastfeeding initiation and duration.     

The association of maternal overweight and obesity with breastfeeding duration

OBJECTIVE: To determine whether maternal prepregnancy overweight or obesity has an independent effect on breastfeeding duration. STUDY DESIGN: A prospective birth cohort study of 1803 live-born children and their mothers ascertained through antenatal clinics at the major tertiary obstetric hospital in Perth, Australia, were followed until 3 years of age. Unconditional logistic, Cox regression, and Kaplan Meier analyses were used to model the association between maternal prepregnancy overweight and obesity and the duration of predominant or any breastfeeding allowing for adjustment of confounders (infant factors: gender, birth weight, gestational age, age solids introduced, and older siblings; maternal factors: smoking, education, age, race, marital status, pregnancy and birth complications, cesarean section, and socioeconomic status). RESULTS: Overweight and obese women were more likely to have discontinued breastfeeding at any time before 6 months than normal weight women (P < .0005) following adjustment for potential confounders. CONCLUSION: We have shown that prepregnancy body mass index is associated with reduced breastfeeding duration, and that mothers who are overweight or obese before pregnancy tend to breastfeed their infants for a shorter duration than normal weight mothers independent of maternal socioeconomic and demographic characteristics.     

Working mothers breastfeed babies more than housewives

AIM: To examine the prevalence and determinants of breastfeeding and to identify perinatal, sociodemographic, psychosocial and environmental factors associated with maternal infant feeding intention. METHODS: A sample of 3734 Greek mothers that delivered their infants in 2000 was recruited in a longitudinal cohort study. Data on duration of breastfeeding was based on a questionnaire answered by 76.6% of the participants at 8-12 months postpartum. RESULTS: The rates of any breastfeeding at 3 and 6 months were 52% and 24%, respectively. The corresponding rates of exclusive breastfeeding were 37% and 17%. From Cox regression analysis mother's intention to breastfeed for a short time and upbringing in the area of Athens were significantly associated with early termination of any breastfeeding and exclusive breastfeeding. A positive intention to breastfeed was influenced by maternal entitlement more than 6 months, delivery in autumn or winter, mother's upbringing abroad and previous breastfeeding experience. CONCLUSIONS: The rates of any breastfeeding and exclusive breastfeeding during the first year of life were fairly satisfactory. Programs to support breastfeeding are necessary and should encourage women to feel positive to breastfeed, focusing particularly on non-working mothers, mothers with a maternity entitlement less than 6 months and mothers who lack previous breastfeeding experience.     

Maternal cigarette smoking and breastfeeding duration

AIM: To examine the relationship between cigarette smoking and breastfeeding duration at 2 wk, 6 mo, and longer. METHODS: Design. A 12-mo longitudinal study. Setting. Two public maternity hospitals in the Perth metropolitan area (Western Australia). Subjects. Eligible mothers of healthy newborn infants. Interventions. Participants completed a self-administered baseline questionnaire while in hospital or shortly after discharge. All women regardless of their chosen infant feeding method were followed up by telephone interview at 4, 10, 16, 22, 32, 40 and 52 wk postpartum. Main outcome measures. Prevalence of breastfeeding at 2 wk, 2 wk to 6 mo and >6 mo in women who smoked during pregnancy, and breastfeeding duration. RESULTS: Women who smoked during pregnancy had a lower prevalence and shorter duration of breastfeeding than non-smoking mothers (28 vs 11 wk, 95% CI 8.3-13.7). This effect remained even after adjustment for age, education, income, father's smoking status, mother's country of birth, intended duration of breastfeeding >6 mo and birthweight (risk ratio 1.59, 95% CI 1.22-2.08). CONCLUSION: Women who smoke during pregnancy are at greater risk of not achieving national and international targets for breastfeeding. Encouraging smoking cessation in the antenatal setting is an area for considerable public health gain.     

Duration of breastfeeding and breastfeeding problems in relation to length of postpartum stay: a longitudinal cohort study of a national Swedish sample

AIM: To investigate the association between length of postpartum stay and duration of breastfeeding and breastfeeding problems, with special focus on early hospital discharge. METHODS: Swedish-speaking women were recruited from all antenatal clinics in Sweden during 3 wk evenly spread over 1 y in 1999 to 2000. In total, 3293 women (71% of those who were eligible) consented to participate in the study. Data were collected by questionnaires in early pregnancy, 2 mo and 1 y postpartum, and from the Swedish Medical Birth Register. For the purpose of this study, only data from the 2709 women (82%) who filled in the question about length of stay in the 2-mo questionnaire were analysed. Women were divided into six groups according to length of postpartum stay (day 1: < 24 h to day 6: > or = 120 h). RESULTS: The median duration of any breastfeeding was 7 mo in women discharged on day 1, and 8 mo in women discharged on any of the following days; a non-significant difference (p = 0.66). Besides hospital policies regarding length of stay (residential area) and number of domiciliary visits, early discharge was associated with the following maternal characteristics, which could be divided into three categories: (1) older, multipara, many children; (2) positive experience of the first breastfeeding after birth; (3) low education, economic problems, smoking, lack of support from partner. Late discharge was associated with operative delivery, preterm birth and low infant birthweight. When these factors were controlled for by Cox regression analysis, no statistical differences were found between the six groups in the relative risk of discontinuing to breastfeed. Breastfeeding problems, such as engorgement and mastitis, did not differ, but women discharged on day 6 or later had fewer problems with sore or cracked nipples during the first week and more problems 4-8 wk postpartum. CONCLUSION: Maternal characteristics may be more important predictors of the duration of breastfeeding than length of stay in hospital after the birth. The effect of domiciliary support needs further research.     

Breastfeeding failure in a longitudinal post-partum maternal nutrition study in Hong Kong

OBJECTIVE: To describe factors associated with breastfeeding failure during the first 6 months post-partum in a sample of Hong Kong Chinese women participating in a longitudinal study of maternal nutrition. METHODOLOGY: Forty-four Hong Kong Chinese lactating mothers who intended to breastfeed exclusively for at least 3 months were recruited and followed for 6 months post-partum. Demographic data were compared with 20 mothers who intended to use formula feeding. Mothers were followed up at 2 and 6 weeks and 3 and 6 months and details of infant feeding practices were obtained. Information was sought on breastfeeding management in hospital, reasons for discontinuation of breastfeeding or for providing supplements to babies and intention to seek, and sources of, lactation support. RESULTS: Thirty-nine mothers who planned to breastfeed completed the follow up. Compared with mothers in the formula-feeding group, breastfeeding mothers were more likely to be professionals or housewives. Continuation of any breastfeeding (total and partial) was noted in 30 (77%), 22 (57%), 16 (41%) and 12 (31%) mothers at 2 and 6 weeks and 3 and 6 months post-partum, respectively. The majority (97%) of mothers stated that they were given information on the benefits and management of breastfeeding. However, late initiation of breastfeeding and providing supplements to babies were common. Perceptions of insufficient milk supply (44%), breast problems (31%) and being too tired (28%) were the main reasons stated for stopping breastfeeding or for providing supplements to babies. Midwives from the postnatal wards and hotlines were the main sources of lactation support. CONCLUSIONS: These results highlight difficulties in sustaining breastfeeding, either exclusive or partial, in Hong Kong Chinese women. Despite being recruited on the basis of intending to exclusively breastfeed for 3 months, less than half these mothers were still breastfeeding and only approximately one-third were exclusively or predominantly breastfeeding at 3 months. More needs to be done within the hospital environment to initiate breastfeeding immediately after birth and to avoid giving unnecessary supplements and more effort is needed to foster a mother's confidence, commitment and knowledge of breastfeeding.     

Prospective associations of breastfeeding and smoking cessation among low‐income pregnant women

Although low‐income pregnant women have high rates of smoking and low rates of breastfeeding, few studies have examined prospective associations between these risk factors in community samples. Doing so may help improve breast‐feeding support programs in this population. We used a secondary analysis of 247 low‐income pregnant smokers in Memphis, Tennessee, who were interviewed up to 4 times (twice during pregnancy and twice through 6 months postpartum). Smoking cessation during prepartum and postpartum was defined as a self‐report of not smoking for ≥1 week and an expired carbon monoxide level of <10 ppm. Multivariable logistic regression analyses were used to determine whether intent to breastfeed was associated with smoking cessation and whether smoking cessation was associated with actual breastfeeding. Models were adjusted for sociodemographic, pregnancy‐related, and smoking‐related confounders. Thirty‐nine percent of participants intended to breastfeed, and 38% did so. Women who intended to breastfeed were 2 times more likely to quit smoking prepartum (adjusted OR = 1.99, 95% CI [1.06, 3.74]), but not postpartum (adjusted OR = 1.27, 95% CI [0.57, 2.84]). Quitting smoking at baseline and during pregnancy was associated with subsequent breastfeeding (adjusted OR 2.27, 95% CI [1.05, 4.94] and adjusted OR = 2.49, 95% CI [1.21, 5.11]). Low‐income women who intended to breastfeed were more likely to quit smoking during pregnancy and those who quit smoking at baseline and prepartum were more likely to breastfeed. Simultaneously supporting breastfeeding and smoking cessation may be very useful to change these important health behaviours among this high‐risk population.     

Maternal smoking and reduced duration of breastfeeding: a review of possible mechanisms

AIM: To systematically review the possible mechanisms by which maternal smoking affects lactation. METHODS: Databases (Medline, CINAHL, Current Contents, Psychinfo, Sociological Abstracts and the Cochrane Library) were searched for smoking and breastfeeding or infant feeding. The Journal of Human Lactation and Birth were hand-searched, searches were also conducted at NMAA's Lactation Resource Centre and references cited were located where appropriate. Articles were divided into the various ways that smoking could affect breastfeeding and were tabulated. RESULTS: Most studies were conducted on small samples of animals or humans; the majority were prior to 1985. Most animal studies exposed the animals to much greater levels of nicotine than those to which humans are exposed. Most studies did not examine if breastfeeding behaviour was similar in smokers and non-smokers, and did not consider that any physiological difference found could be the result of poor lactation practices, rather than the cause of poor lactation in smokers. The definition of breastfeeding infants was also problematic in many studies. The effect of smoking on oxytocin in women was only examined in one study, and no effect was found, yet a negative effect of smoking on oxytocin release is reported in the breastfeeding literature. CONCLUSION: Although there is consistent evidence that women who smoke breastfeed their infants for a shorter duration than non-smokers, the evidence for a physiological mechanism is not strong.     

Maternal employment and the initiation of breastfeeding

This study examines whether planning to be employed postpartum has an effect on initiation of breastfeeding. Data were collected from questionnaires completed by mothers who were subjects in the prospective, population-based, Avon Longitudinal Study of Pregnancy and Childhood. The mothers of 10,530 full-term singleton infants gave information during pregnancy on their postpartum employment plans and their initial infant feeding methods. Information was also given by 7642 of these mothers on the timing of their postpartum employment plans. Adjusted logistic regression was performed to identify associations between (a) "any" plans to work postpartum and the initiation of breastfeeding, and (b) the timing of the commencement of work postpartum, and the initiation of breastfeeding. A total of 8316 (79%) of the women initiated breastfeeding. The decision to breastfeed was not associated with "any" plans to work postpartum. However, women who planned to commence work prior to 6 wk postpartum were significantly less likely to initiate breastfeeding compared with those not intending to work postpartum. Older, more highly educated women, women who had or were planning to attend childbirth classes, women who were breastfed as infants, women who did not smoke and women who were giving birth to their first child were significantly more likely to initiate breastfeeding. Conclusion: Planning to return to employment prior to 6 wk postpartum reduces the likelihood of initiating breastfeeding. As increasing numbers of mothers are returning to work shortly after the birth of their child, this finding could have implications for maintaining the current level of breastfeeding.     

Socio-economic determinants, maternal smoking and coffee consumption, and exclusive breastfeeding in 10205 children

AIM: To examine socio-economic factors, smoking, coffee consumption and exclusive breastfeeding duration. METHODS: This study was part of a prospective cohort study of children born between 1 October 1997 and 1 October 1999 (the All Babies in Southeast Sweden (ABIS) study). Eleven socio-economic characteristics (parental employment, civil status, whether parents were born in Sweden, parental education, residence at birth and during child's first year, crowded living), maternal smoking, coffee consumption, infant sex, siblings, parental age, and maternal alcohol consumption during pregnancy were analysed using logistic regression and Cox's proportional hazards method. All data were obtained through questionnaires distributed at infant birth and at 1 y of age. Exclusive breastfeeding duration<4 mo and actual breastfeeding duration were our main outcome measures. RESULTS: Out of 10205 infants, 2206 (21.6%) were exclusively breastfed for less than 4 mo ("short exclusive breastfeeding"; SEBF). Backward stepwise regression analysis identified the following risk factors for SEBF: maternal smoking (95% confidence interval for adjusted odds ratio, 95% CI AOR 2.00-2.82), low maternal education (95% CI AOR 1.45-2.19), maternal employment less than 3 mo during pregnancy (95% CI AOR 1.17-1.54), paternal age相似文献   

Seeing other women breastfeed: how vicarious experience relates to breastfeeding intention and behaviour

Vicarious experience gained through seeing women breastfeed may influence infant feeding decisions and self‐efficacy. Our aim was to measure the attributes of seeing breastfeeding and to investigate how these relate to feeding intention (primary outcome) and behaviour (secondary outcome). First, we developed a Seeing Breastfeeding Scale (SBS), which consisted of five attitudes (Cronbach's alpha of 0.86) to most recently observed breastfeeding: ‘I felt embarrassed’; ‘I felt uncomfortable’; ‘I did not know where to look’; and ‘It was lovely’ and ‘It didn't bother me’. Test–retest reliability showed agreement (with one exception, kappas ranged from 0.36 to 0.71). Second, we conducted a longitudinal survey of 418 consecutive pregnant women in rural Scotland. We selected the 259 women who had never breastfed before for further analysis. Following multiple adjustments, women who agreed that ‘It was lovely to see her breastfeed’ were more than six times more likely to intend to breastfeed compared with women who disagreed with the statement [odds ratio (OR) 6.72, 95% confidence interval (CI) 2.85–15.82]. Women who completed their full‐time education aged 17 (OR 3.09, 95% CI 1.41–6.77) or aged 19 (OR 7.41 95% CI 2.51–21.94) were more likely to initiate breastfeeding. Women who reported seeing breastfeeding within the preceding 12 months were significantly more likely to agree with the statement ‘It was lovely to see her breastfeed’ (P = 0.02). Positive attitudes to recently seen breastfeeding are more important determinants of feeding intention than age of first seeing breastfeeding, the relationship to the person seen and seeing breastfeeding in the media.     

Sociodemographic and atopic factors affecting breastfeeding intention in Chinese mothers

OBJECTIVE: The factors accounting for the low 'ever breastfeeding' rate in Hong Kong remain unclear. The objective of this survey was to study the intention and planned duration of breastfeeding in Chinese women in Hong Kong, and to investigate the sociodemographic and atopic factors affecting the intention to breastfeed. METHODS: All Chinese mothers who were Hong Kong residents and who delivered their babies in a University teaching hospital were given a self administered and anonymous Chinese questionnaire within 1 day postpartum. The questionnaire included items on sociodemographic data, the presence of allergic diseases in the families, and the intention and planned duration of breastfeeding for their newborn babies. RESULTS: A total of 1374 eligible questionnaires were collected. About one-third of mothers were born outside Hong Kong and the majority (78%) of them were aged between 25 and 40 years. Logistic regression revealed that only socioeconomic factors, namely older maternal age (odds ratio (OR) 2.10, 95% confidence interval (CI) 1.14-3.89), parity (OR 3.08, 95% CI 1.02-9.27) and higher educational background (OR 2.87, 95% CI 1.92-4.27), significantly affected the intention to breastfeed. In addition, mothers born outside Hong Kong and those with first babies, had a longer intended duration of breastfeeding (P-values < 0.001 and 0.033, respectively). A family history of atopic disorders in parents or siblings did not influence the breastfeeding intention of these Chinese mothers. CONCLUSION: Several sociodemographic factors, rather than a history of atopic disorders, of Chinese mothers in Hong Kong affected their intention to breastfeed and the planned duration of breastfeeding.     

Which mothers wean their babies prematurely from full breastfeeding? An Australian cohort study

Aim:  To identify the maternal and infant characteristics associated with an early transition from full breastfeeding to complementary or no breastfeeding during the first 2 months of life in a large, representative cohort of Australian infants.
Method:  Multinomial logistic modelling was performed on data for infants with complete breastfeeding and sociodemographic data (N = 4679) including maternal age, education, smoking, employment, pregnancy and birth outcomes.
Results:  Ninety-one percent of women initiated breastfeeding. Sixty-nine percent of infants were being fully breastfed at 1 month, and 59% were fully breastfed at 2 months. Maternal characteristics – age less than 25 years, smoking in pregnancy, early full-time postnatal employment and less educational attainment – were associated with early breastfeeding cessation. Infant factors – multiple birth, caesarean birth, infant or first birth – were associated with a transition to complementary breastfeeding in the first postnatal month.
Conclusion:  Breastfeeding duration is substantially affected by breastfeeding outcomes in the first postpartum month. The first month is an important window for evidence-based interventions to improve rates of full breastfeeding in groups of women identified as at risk of early breastfeeding cessation.     

Severe maternal morbidity and breastfeeding outcomes in the early post‐natal period: a prospective cohort study from one English maternity unit

Previous research has identified potential issues of establishing and maintaining breastfeeding among women who experience severe maternal morbidity associated with pregnancy and birth, but evidence in the UK maternity population was scarce. We explored the association between severe maternal morbidity and breastfeeding outcomes (uptake and prevalence of partial and exclusive breastfeeding) at 6 to 8 weeks post‐partum in a UK sample. Data on breastfeeding outcomes were obtained from a large cohort study of women who gave birth in one maternity unit in England to assess the impact of women's experiences of severe maternal morbidity (defined as major obstetric haemorrhage, severe hypertensive disorder or high dependency unit/intensive care unit admission) on their post‐natal health and other important outcomes including infant feeding. Results indicated that among women who responded (n = 1824, response rate = 53%), there were no statistically significant differences in breastfeeding outcomes between women who did or did not experience severe morbidity, except for women with severe hypertensive disorder who were less likely to breastfeed either partially or exclusively at 6 to 8 weeks post‐partum. Rather, breastfeeding outcomes were related to multi‐dimensional factors including sociodemographic (age, ethnicity, living arrangement), other pregnancy outcomes (neonatal intensive care unit admission, mode of birth, women's perceived control during birth) and post‐natal psychological factors (depressive symptoms). Women who experience severe maternal morbidity can be reassured that establishing successful breastfeeding can be achieved. More studies are required to understand what support is best for women who have complex health/social needs to establish breastfeeding.     

Duration of breastfeeding among first-time mothers in the United States: results of a national survey

Aim: To determine the characteristics of primiparous women who breastfeed for only short periods of time. Methods: The 2002 National Survey of Family Growth was used to analyze the characteristics of a national probability sample of 3229 first-time US mothers aged 15 to 44 y with children ages 1 to 18 y old, 1960 of whom breastfed. Main outcome measures in the cross-sectional study included breastfeeding at birth and at 3 mo as determined by in-person, computer-assisted interviews conducted by trained female interviewers. Results: Sixty-two percent of first-time mothers with singleton live births initiated any breastfeeding and 36% were still breastfeeding at 3 mo. Those who were older, married, and at higher educational levels were significantly more likely to continue breastfeeding beyond 3 mo. These same demographic factors were associated with differences in breastfeeding rates both early (within the first week of life) and consistently over the first 3 mo. In multivariate analyses, only educational level remained as a predictor of breastfeeding.
Conclusion: Targeted breastfeeding interventions for young, single, less-educated women are warranted in a culturally sensitive context, both prenatally and immediately postpartum, to improve the duration of breastfeeding among first-time mothers in the US.     

Secular trends in breastfeeding and parental smoking

To explore the association between smoking and breastfeeding, we obtained data from a retrospective questionnaire-based national survey comprising a random sample (n = 34 799) of all mothers giving birth in Norway 1970-91. Variables studied were postpartum smoking habits for both parents, duration of breastfeeding, infant's year of birth and parental age. The response rate was 70% (n = 24 438). During the study period, the maternal postpartum smoking prevalence decreased from 38% to 26%. The proportion breastfeeding at 6 months increased from 15% to 44% among smokers, and from 30% to 72% among non-smokers. In spite of a considerable increase in breastfeeding both among smokers and non-smokers, the proportion of breastfeeding, non-smoking women at 6 months was twice that of smoking women during the whole period. Furthermore, the duration of breastfeeding was shorter among young mothers and when the fathers were smoking. There was epidemiological evidence that the effect on breastfeeding of smoking might represent both biological and social mechanisms.     

Infant milk feeding practices in the Netherlands and associated factors

AIM: The aim of the study was to describe infant feeding practices and associated factors, and to explore mothers' main reasons for starting and stopping breastfeeding. METHODS: We performed a national inquiry into milk feeding practices among 9133 Dutch infants aged < 7 mo by means of a questionnaire. RESULTS: 78% of mothers initiated breastfeeding. At 1 and 4 mo, respectively, 51 and 25% of infants were fed primarily on human milk; after 6 mo, only 15% of mothers still provided human milk as the only source of milk feeding. During the whole 6-mo period, another 11 to 18% was fed on both breast and formula milk. Women initiating breastfeeding were more likely to be higher educated, have a higher-educated partner, be non-smokers, have a full-time job, and be primiparous. In addition, breastfeeding initiation rate was higher for women born outside the Netherlands. Longer duration of breastfeeding was mostly found amongst higher-educated, non-smoking women. The odds for continuation of breastfeeding after 4 mo increased when mothers' working hours did not exceed 16 h/wk. Infant delivery at home was associated with a higher initiation rate as well as longer duration of breastfeeding compared to hospital delivery. Infants born after 38 wk of gestation, with a birthweight of 3500 g had higher odds to be breastfed for a longer period. CONCLUSION: Only a minority of Dutch infants is breastfed for 6 mo. Maternal and infant characteristics are important predictors of breastfeeding initiation and duration.     

Maternal obesity and initiation and duration of breastfeeding: data from the longitudinal study of Australian children

The aim of this paper is to investigate whether the lower rate of breastfeeding at 6 months by overweight and obese mothers is primarily due to these women giving up breastfeeding in the first week postpartum using a cross-sectional population survey. The sample is children from the infant cohort (about 12 months of age) of Wave 1 (2004) of the Longitudinal Study of Australian Children for whom breastfeeding and maternal information were available ( n  = 3075). Definitions used: normal-weight body mass index (BMI, kg/m²) 20 to <25, overweight BMI 25 to <30, obese BMI ≥30. Breastfeeding initiation was 95.1% for normal-weight women, 92.8% for overweight women and 87.1% for obese women. At 6 months, 64% of normal-weight women were breastfeeding, compared with 54% of overweight and 44% of obese women. On multivariate analysis, for women who initiated breastfeeding, overweight women had an odds ratio (OR) of 1.52 [95% confidence interval (CI) 1.02, 2.28] and obese women had an OR of 2.54 (95% CI 1.70, 3.79) of stopping breastfeeding by 1 week compared with normal-weight women (adjusted for maternal age, education, smoking, level of socio-economic disadvantage, caesarean birth, admission to special care nursery). For women who breastfed for at least 1 week, overweight women had an adjusted OR of 1.26 (1.04, 1.53) and obese women had an adjusted OR of 1.38 (1.10, 1.73) of ceasing to breastfeed before 6 months, compared with normal-weight women. In conclusion, among overweight/obese women who initiate breastfeeding, higher rates of cessation of breastfeeding in both the immediate postpartum period and in the first 6 months contribute to the shorter duration.     

Breastfeeding duration and postpartum psychological adjustment: role of maternal attachment styles

Aim:   Depressive and anxiety symptoms are common in new mothers. The aim of this study is to explore the link between postpartum psychological adjustment and feeding preferences of the mothers.
Methods:   Sixty mothers and newborns were enrolled in this prospective, longitudinal study. Maternal depressive symptoms were screened by the Edinburgh Postpartum Depression Scale (EPDS), and maternal anxiety level was assessed by the State-Trait Anxiety Inventory at 1 month postpartum. The Multidimensional Scale of Perceived Social Support was used for the assessment of maternal social support. The Adult Attachment Scale was used to determine the attachment style of the mother. Infants were examined and evaluated at 1 and 4 months of life.
Results:   All mothers started breastfeeding their infants postpartum; 91% and 68.1% continued exclusive breastfeeding at 1 and 4 months, respectively. The first-month median EPDS score of mothers who breastfeed at the fourth month was statistically significantly lower than those who were not breastfeeding (6 and 12, respectively) ( P  = 0001). The first-month median EPDS score of mothers with secure attachment was lower than the median score of mothers with insecure attachment (5 and 9, respectively) ( P  < 0001). Exclusive breastfeeding rate was not statistically different among mothers with secure and insecure attachment styles. The median state and trait anxiety scores and social support scores of mothers were not different between groups according to breastfeeding status.
Conclusions:   This study has shown an association between higher EPDS scores and breastfeeding cessation by 4 months after delivery.     

Predictors of breastfeeding exclusivity among migrant and Canadian‐born women: results from a multi‐centre study

The objective of this study was to examine and compare predictors of breastfeeding exclusivity among migrant and Canadian‐born women. As part of a longitudinal study, a sample of 1184 mothers were recruited from 12 hospitals in Canada and completed questionnaires at 1 and 16 weeks post‐partum that included diverse questions from the following domains: demographic, social, migration, obstetrical, breastfeeding and maternal mood. After bivariate analysis, multivariate logistic regression analysis was completed to examine and compare predictors of exclusive breastfeeding at 16 weeks post‐partum. Among migrant women, factors predictive of breastfeeding exclusivity included non‐refugee immigrant or asylum‐seeking status, residence in Toronto or Vancouver, maternal age of ≥35 years, feels most comfortable in the country of origin or nowhere and higher Gender‐related Development Index of the country of origin. Factors predictive of not exclusively breastfeeding included maternal age of <20 years, not planning to exclusively breastfeed, not making the decision to breastfeed before pregnancy and not exclusively breastfeeding at 1 week post‐partum. Among Canadian‐born women, factors predictive of a lower likelihood of breastfeeding exclusivity included not living with father of infant, infant neonatal intensive care unit admission, planned duration of exclusive breastfeeding for <6 months, not exclusively breastfeeding at 1 week post‐partum and Edinburgh Postnatal Depression Scale score of ≥10. The only similar risk factor predicting a lower likelihood of breastfeeding exclusivity between migrant and Canadian‐born women was not exclusively breastfeeding at 1 week post‐partum; all other risk factors were dissimilar, suggesting that these groups might benefit from different strategies to optimise breastfeeding outcomes.
