Factors that influence women’s decision on infant feeding: An integrative review

BackgroundMany women stop breastfeeding earlier than what they intended prior to birth. Although there are many studies that focus on the factors that influence women’s antenatal breastfeeding decisions, the factors that influence women’s decisions during the continuum of antenatal and postnatal period are less known.AimTo understand and synthesise the contemporary factors that influence women’s decisions on infant feeding from the antenatal period and across the breastfeeding continuum.MethodFive online databases (CINAHL, Medline, PubMed, Scopus and Web of Science) were searched. We included original search articles that were published since 2015 to August 2021 and were available in English. The framework of Whittemore and Knafl was used to guide this integrative literature review. Out of the 872 articles identified, 14 studies met the inclusion criteria of our study. We used theory of birth territory and midwifery guardianship to synthesise the interactions between the themes.FindingsFive main themes were identified: (a) Women’s own views, (b) Family and friend’s preferences and advice, (c) Health professional’s preference, advice and practice, (d) Sociocultural norms, and (e) Media representation. The interaction between the themes was explained based on women’s intrinsic and extrinsic power outlined in the birth territory and midwifery guardianship theory.ConclusionThe factors that influence women’s decisions towards infant feeding methods are complex and multi-dimensional. Promoting and supporting women towards breastfeeding need to focus on the factors that are tailored for a woman within her social network where she can feel safe about her breastfeeding decisions.     

Analyzing fertility histories: Do restrictions bias results?

The straightforward tests we have conducted lead to two major conclusions. First, parameter estimates, such as the proportions that practice contraception or that breastfeed, can be biased in data restricted to the last closed and open interval. This is particularly true the further back in time one goes. However, the second conclusion is that these restrictions do not bias estimates of the structure of the relationships predicting fertility. This may seem surprising, and perhaps even magical. The reason is that multivariate life table techniques allow one to reach the same conclusion even if the proportions in various categories are altered by a criterion such as limiting the analysis to intervals begun by the last and next-to-last live births. Limiting the analysis in this way means that there are fewer short intervals and thus fewer cases of intervals with characteristics associated with short intervals (e.g., no contraceptive use, no breastfeeding, or infant mortality). As long as the model specified in the multivariate life table is an appropriate one, that is, it is not misspecified, and as long as the skew produced by the WFS restriction is not too extreme, then the multivariate life table procedures can produce unbiased estimates of the structure of the relationships predicting birth interval dynamics. Thus even though the WFS data are in fact inappropriate for some simple parameter estimation procedures, they appear to be adequate for the more complex multivariate procedures of the sort used here. Several caveats must be added to the foregoing results. First, we have performed this test in only one country, Korea; it is possible that the same results might not be obtained in other countries. We expect, however, that they would. Second, our procedure only looks at the first 40 months of experience in the birth interval. A procedure that incorporates the long tails of the birth interval distribution may obtain different results. In fact, we caution against analyzing the tail of the distributions using data from the normal WFS sample, since these would be most affected by the restriction to last closed and open intervals. Third, the extent to which these results are generalizable to other types of substantive problems is unknown at present. We suspect, however, that examining the determinants of lengths of breastfeeding will produce similar results. Finally, even with multivariate procedures, it would be highly misleading to impose the WFS restrictions and then examine trends in the length of birth intervals.(ABSTRACT TRUNCATED AT 400 WORDS)     

Intensive Parenting: Fertility and Breastfeeding Duration in the United States

Using 30 years of longitudinal data from a nationally representative cohort of women, we study the association between breastfeeding duration and completed fertility, fertility expectations, and birth spacing. We find that women who breastfeed their first child for five months or longer are a distinct group. They have more children overall and higher odds of having three or more children rather than two, compared with women who breastfeed for shorter durations or not at all. Expected fertility is associated with initiating breastfeeding but not with how long mothers breastfeed. Thus, women who breastfeed longer do not differ significantly from other breastfeeding women in their early fertility expectations. Rather, across the life course, these women achieve and even exceed their earlier fertility expectations. Women who breastfeed for shorter durations (1–21 weeks) are more likely to fall short of their expected fertility than to achieve or exceed their expectations, and they are significantly less likely than women who breastfeed for longer durations (≥22 weeks) to exceed their expected fertility. In contrast, women who breastfeed longer are as likely to exceed as to achieve their earlier expectations, and the difference between their probability of falling short versus exceeding their fertility expectations is relatively small and at the boundary of statistical significance (p = .096). These differences in fertility are not explained by differences in personal and family resources, including family income or labor market attachment. Our findings suggest that breastfeeding duration may serve as a proxy for identifying a distinct approach to parenting. Women who breastfeed longer have reproductive patterns quite different than their socioeconomic position would predict. They both have more children and invest more time in those children.     

Using Retrospective Surveys for Estimating the Effects of Breastfeeding and Childspacing on Infant and Child Mortality

Recent contributions to our knowledge about the effects of breastfeeding and pace of childbearing on early child mortality have originated in the analysis of birth histories elicited from retrospective interviews. The validity of these findings has been questioned on the ground that when the timing of events is systematically distorted, estimates of effects will be affected by serious biases. In addition, it has been argued that the results obtained are highly sensitive to the models used and the techniques of estimation applied to calculate estimates of effects. In this paper we review the most important criticisms levelled against recent findings and interpretations and show that they rest on propositions of questionable validity.     

Birth of a very low birth weight preterm infant and the intention to breastfeed 'naturally'

An interpretive phenomenological study involving 17 Australian parents was undertaken to explore parents' experiences of breastfeeding very low birth weight (VLBW) preterm infants from birth to 12 months of age. Data were collected from 45 individual interviews held with both mothers and fathers, which were then transcribed verbatim and analysed using thematic analysis. From this study, the analysis identified the following themes: the intention to breastfeed naturally; breast milk as connection; the maternal role of breast milk producer; breastmilk as the object of attention; breastfeeding and parenting the hospitalised baby and the demise of breastfeeding. The discussion presented here presents the theme of the intention to breastfeed 'naturally'. This study found that all of the participant women decided to breastfeed well before the preterm birth, and despite the birth of a VLBW preterm infant continued to expect the breastfeeding experience to be normal regardless of the difference of the postpartum experience. It is without doubt that for these parents the pro-breastfeeding rhetoric is powerfully influential and thus successful in promoting breastfeeding. Furthermore, all participants expected breastfeeding to be 'natural' and satisfying. There is disparity between parents' expectations of breastfeeding 'naturally' and the commonplace reality of long-term breast expression and uncertain at-breast feeding outcomes. How the parents came to make the decision to breastfeed their unborn child -- including the situations and experiences that have influenced their decision making -- and how the preterm birth and the dominant cultures subsequently affected that decision will be discussed. The findings have implications for midwifery education and maternity care professionals who support parents making feeding decisions early in pregnancy and those striving to breastfeed preterm infants.     

Breastfeeding practices in women with type 1 diabetes: A discussion of the psychosocial factors and policies in Sweden and Australia

BackgroundWomen with type 1 diabetes (T1DM) face many challenges during their pregnancy, birth and in the postnatal period, including breastfeeding initiation and continuation while maintaining stable glycaemic control. In both Sweden and Australia the rates of breastfeeding initiation are high. However, overall there is limited information about the breastfeeding practices of women with T1DM and the factors affecting them. Similarities in demographics, birth rates and health systems create bases for discussion.AimThe aim of this paper is to discuss psychosocial factors, policies and practices that impact on the breastfeeding practices of women with T1DM.FindingsSwedish research indicates that the overall breastfeeding rate in women with T1DM remains significantly lower than in women without diabetes in the first 2 and 6 months after childbirth with no differences in exclusive breastfeeding. Breastfeeding initiation and continuation among women with T1DM in Sweden has been shown to be influenced by health services delivery, supportive breastfeeding polices and socio-economic factors, particular perceived support from social networks and health professionals.ConclusionThere is limited research on the impact of attitudes towards breastfeeding, emotional and social well-being and diabetes-related stress on the decision of women with T1DM to initiate and continue to breastfeed for at least 6 months. A more comprehensive understanding of the breastfeeding practices and psychosocial factors operating during the first 6 months after birth for women with T1DM will be instrumental in the future design of interventions promoting initiation and continuation of breastfeeding in Sweden, Australia and elsewhere.     

Improving breastfeeding rates in an “at risk” population

A new public health frontier challenging maternity care is addressing the sub-optimal breastfeeding rates of women who are obese. Despite the World Health Organisation's recommendation that breastfeeding is initiated within the first hour of birth and continued exclusively for six months, less than half of infants and young children globally are optimally breastfed. While initiation rates of exclusive breastfeeding immediately after birth are as high as 90 percent in Australia, this rate dramatically declines in the first few weeks postpartum, with only approximately 15 percent of infants exclusively breastfed to five months of age (less than 6 months). The aim of this paper was to highlight difficulties obese women have breastfeeding and highlight implications for research and practice.     

Comparison of breastfeeding in rural areas of Sweden and Australia – a cohort study

BackgroundBreastfeeding rates in Sweden and Australia appears to be decreasing in both countries. National statistics shows that 87% of infants in Sweden and 73% in Australia receive any breastfeeding two months of age.AimTo compare women's experiences of breastfeeding in Sweden and Australia and to identify factors associated with breastfeeding two months after birth.MethodsA cohort study in two rural hospitals in mid Sweden (n = 300) and north-eastern Victoria in Australia (n = 91) during 2007–2009. Participants responded to questionnaires in mid pregnancy and two months after birth. Crude and adjusted odds ratios with a 95% confidence interval were used to detect differences between women in both cohorts.FindingsWomen in Sweden (88.3%) were more likely to report any breastfeeding of the baby two months after birth (OR 2.41; 95% CI: 1.33–4.38) compared to women in Australia (75.8%) but were less satisfied with breastfeeding support and information. The most important factor associated with breastfeeding at two months postpartum for the Swedish women was to have received sufficient information about breastfeeding on the postnatal ward (OR 2.3; 95% CI 1.41–4.76) while for the Australian women receiving the best possible help when breastfeeding for the first time was most important (OR 4.3; 95% CI 1.50–12.46).ConclusionThe results indicate that Swedish women were more likely than their Australian counterparts to breastfeed the baby two months after birth. The findings demonstrated the importance of sufficient information and help when breastfeeding is initiated.     

Breastfeeding as a means of contraception

The University of the Philippines Institute of Public Health (UPIPH) and the Family Health International (FHI) brought together health professionals, nutritionists, and family planning experts from different parts of the world to share and gain insights into the issue of breastfeeding and contraception. The participants met in Manila in 1983 and analyzed research findings on breastfeeding and discussed their implications relevant to nutrition and family planning policies and programs. Studies conducted in several countries show a general decline of breastfeeding practice in both urban and rural areas. The issue appears to be not whether women in developing countries breastfeed their infants but for how long. Popkin cites a study in Thailand, which showed very little change in the proportion of babies ever breastfed but large declines in the duration of breastfeeding from 1969-79. In the Philippines, national surveys since 1973 indicate that mothers throughout the country practice breastfeeding but do so for a relatively short period. Scientific data supporting the folk belief that breastfeeding delays the return of fertility after childbirth is growing. The phenomenon is believed to be governed by a sophisticated control mechanism in the female reproductive system. Some researchers suggest that prolactin may be responsible for the delay of fertility in breastfeeding mothers. In a series of studies done in the Philippines and Australia, researchers Barbara Gross and C.J. Eastman found that high prolactin levels were almost always associated with proloned amenorrhea during lactation. A decline in prolactin concentrations accompanied the resumption of menstruation. Gross and Eastman found evidence of ovulation before the 1st menses in only 1 out of 54 fully breastfeeding mothers, or less than 2%. This implies that at least the first few menses of most fully breastfeeding mothers are not accompanied by ovulation, suggesting that breastfeeding continues to affect fertility even after the resumption of breastfeeding. Zablan's study in the Philippine analyzed the various factors contributing to fertility reduction. Breastfeeding appeared to have the greatest impact on the Filipino woman's level of fertility. Zablan points out that, while breastfeeding is a major factor influencing fertility in the Philippines, it "can be relied upon only to postpone childbearing (and then only at the aggregate level), but not to prevent childbearing altogether." Much work needs to be done to help people realize the value of breastfeeding, to encourage mothers to practice it, and to do so for as long as possible.     

Cessation of breastfeeding in association with oxytocin administration and type of birth. A prospective cohort study

Background

Some studies have suggested an association between synthetic oxytocin administration and type of birth with the initiation and consolidation of breastfeeding.

Dynamics of contraceptive use and breastfeeding during the post-partum period in Peru and Indonesia

This paper examines the interaction between contraceptive use and breastfeeding in relation to resumption of intercourse and duration of amenorrhea post-partum. We used data from the month-by-month calendar of reproductive events from Demographic and Health Surveys (DHS) in Peru and Indonesia. The analyses show that breastfeeding women were less likely than non-breastfeeding women to have resumed sexual intercourse in the early months post-partum in both countries. In Peru, but not in Indonesia, breastfeeding women had a significantly lower odds than non-breastfeeding women of adopting contraception. Although the likelihood of contraceptive adoption was highest in the month women resumed menstruation in both countries, about ten per cent of subsequent pregnancies occurred to women before they resumed menses. These results emphasize the importance of integrating breastfeeding counselling and family planning services in programmes serving post-partum women, as a means of enabling those who wish to space their next birth to avoid exposure to the risk of a pregnancy that may precede the return of menses.     

The effects of breastfeeding and pace of childbearing on mortality at early ages

The effects of the pace of childbearing and breastfeeding practices on infant mortality have rarely been considered together. In this paper, we design and use a set of methodological tools to test a variety of hypotheses postulating the effects of breastfeeding and pace of childbearing on mortality in infancy and early childhood, the mechanisms through which those effects operate, and the contingencies that strengthen or weaken them. The strong effects of both length of breastfeeding and the pace of childbearing on the risks of child death suggest that neither of them exerts an impact on mortality totally mediated by the other. Social and demographic factors (such as age of child, education of mother, and region of residence) also condition the impact of breastfeeding and pace of childbearing on mortality.     

Breastfeeding Patterns and Determinants in the Near East: An Analysis for Four Countries

Few detailed studies of the determinants of breastfeeding behaviour have been carried out, especially in the Middle East. We provide a comparative investigation of patterns and determinants of breastfeeding in four Middle East countries (Egypt, Jordan, Tunisia and Yemen) based on WFS data. Differences in factors influencing ever-breastfeeding, continuing breastfeeding from very short to moderate durations, and extending breastfeeding into the second year are observed, indicating ‘structural shifts’ in the determinants of breastfeeding. Differences between countries are also found which can only roughly be associated with differences in modernization and urbanization. Lack of consistently negative effects of women's education and work status variables is attributed to the extremely low levels of both in the region. Interesting results are observed regarding effects of pill use and sex of child (boys being breastfed longer), suggesting the need for thorough studies to explain these findings further.     

Obesity and breastfeeding: The strength of association

Obesity and attendant co-morbidities are an emergent problem in public health. Much attention has focused on prevention, especially during the perinatal period. Breastfeeding is considered a possible protective factor for obesity in childhood, influencing gene–neuroendocrine–environment–lifestyle interaction. Therefore, breastfeeding and its longer duration are probably associated with lower development of childhood obesity. Through human milk, but not formula, the child assumes greater bioactive factors contributing to immunological, endocrine, development, neural and psychological benefits. Contrarily, other studies did not confirm a critical role of breast milk. Confounding factors, especially maternal pre-pregnancy overweight, may influence breastfeeding effects. This review summarises what is known about the possible relationship between breastfeeding and prevention of obesity development.ConclusionBreastfeeding appears to represent a protective factor for obesity in childhood, although evidence is still controversial and underlying mechanisms unclear. Further research is needed to improve knowledge on overweight/obesity and breastfeeding.     

Reliability of reasons for early termination of breastfeeding: application of a bivariate probability model with sample selection to data from surveys in Malaysia in 1976-77 and 1988-89

Although extensively collected, data on people's reasons for their behaviour provided retrospectively have been met with some scepticism on the grounds that they may be subject to biases and errors that jeopardize their usefulness. This study investigates, for a sample of 1,327 births, the reliability with which women in Peninsular Malaysia recalled, at intervals 12 years apart, reasons for not initiating or for stopping breastfeeding less than 3 months after a birth. Overall, we find low to moderate reliability of recall. Levels of reliability are relatively high for some reasons (the child died and no or insufficient milk) but low for some others (child ill, breastfeeding inconvenient). Results from selection models show that reliability does not vary with the length of time since the child's birth but is inversely related to socio-economic status (proxied by education and employment). Social status, social norms, and health-related factors appear to be significant influences on women's consistency of reporting.     

Impact of COVID-19 on breastfeeding intention and behaviour among postpartum women in five countries

BackgroundStudies regarding the impact of COVID-19 on breastfeeding have mostly used single- country samples or a qualitative design.AimThe objective of this study was to examine breastfeeding intention during pregnancy and breastfeeding behaviour among postpartum women in five countries during the COVID-19 pandemic and the associated factors.MethodsAn online questionnaire survey was conducted in Thailand, the United Kingdom, South Korea, Taiwan, and Brazil from July through November 2021. The study participants included 3253 mothers within six months of birth.FindingsAbout 90% of participants intended to breastfeed during pregnancy and 85.7% reported breastfeeding in the past 24 h. More than half reported their breastfeeding duration being as planned or longer despite COVID-19. Multivariate logistic regression models showed that being multiparous, ever tested COVID-19 positive, and having positive breastfeeding beliefs were associated with increased odds for intention to breastfeed during pregnancy. Lower maternal educational level, being primiparous, ever tested COVID-19 positive, and experiencing food insecurity were associated with decreased odds for breastfeeding duration being as planned or longer. Vaginal birth, currently working or on maternity leave, breastfeeding beliefs, breastfeeding support from spouse/partner/friend/relative, online support groups, and in-person or telephone contact with healthcare professionals were associated with increased odds for breastfeeding duration being as planned or longer.ConclusionBreastfeeding intention and behaviour remained high during the COVID-19 pandemic. Online support groups and telephone contact with health professionals were effective during the pandemic.     

Factors that positively influence in-hospital exclusive breastfeeding among women with gestational diabetes: An integrative review

ProblemWomen with gestational diabetes have higher rates of introducing infant formula before leaving hospital.BackgroundDespite health professional support, less women with gestational diabetes exclusively breastfeed in hospital.AimTo find factors that positively influence in-hospital exclusive breastfeeding practices among women with gestational diabetes.MethodsAn online search was performed in Medline, Scopus, Pubmed, CINAHL and Cochrane databases. Studies containing the keywords gestational diabetes and breastfeeding were retrieved.FindingsAuthors identified 1935 papers from search criteria. Twenty-six papers with no restrictions on research design met inclusion criteria and were included in the review. Factors were divided into personal, antenatal, intrapartum and postnatal factors. The main modifiable factors that were associated with improved in-hospital exclusive breastfeeding rates were having a strong intention to breastfeed, being confident, feeling supported and having continuity of education and support. Women’s main reasons to introduce formula were related to baby’s hypoglycaemia, delayed lactogenesis II and perceived low milk supply. Skin-to-skin contact after birth combined with frequent breastfeeds were effective ways to improve in-hospital exclusive breastfeeding rates.ConclusionInfluencing factors such as women’s breastfeeding intention, confidence and ongoing support are no different to the general population of women. However, promoting skin-to-skin contact after birth combined with frequent feeds are crucial for women with gestational diabetes who are more likely to introduce formula due to delayed lactogenesis II and fear of neonatal hypoglycaemia. There is a need for developing educational and supportive interventions that are tailored specifically for women who have gestational diabetes.     

To what extent does breastfeeding explain Birth-interval effects on early childhood mortality?

This article shows that in Nepal breastfeeding almost completely explains the effects of following birth interval on childhood mortality during the first 18 months of age and partially explains the effect of following birth interval on childhood mortality between 18 and 60 months of age. Breastfeeding does not explain the effect of preceding birth interval on childhood mortality. The analysis is based on application of hazard models to data from the 1976 Nepal Fertility Survey.     

Breastfeeding initiation and support: A literature review of what women value and the impact of early discharge

ProblemEarly discharge following birth has become an emerging phenomenon in many countries. It is likely early discharge has an impact on the establishment of breastfeeding.ObjectiveTo critically appraise the evidence on what women value in relation to breastfeeding initiation and support, and investigate the impact early discharge can have on these values.MethodA literature search was conducted for publications since 2005 using the following databases: Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline, Scopus and PsycINFO; 21 primary articles were selected and included in the review.FindingsThere is no standard definition for ‘early discharge’ worldwide. Due to inconsistent definitions worldwide and minimal literature using a 24 h definition, research defining early discharge as up to 72 h postpartum is included. Seven key factors in relation to breastfeeding initiation and support following early discharge were identified, namely trust and security, consistent advice, practical breastfeeding support, breastfeeding education, comfortable environment, positive attitudes and emotional support, and individualised care.ConclusionThe findings suggest individualised postnatal lengths of stay may be beneficial for the initiation of breastfeeding. Five values were not impacted by early discharge, but rather individual midwives’ practice. There is consensus in the literature that early discharge promoted a comfortable environment to support breastfeeding initiation. Wide variations in the definition of early postnatal discharge made it difficult to draw influential conclusions. Therefore, further research is required.     

Trajectories of Unintended Fertility

Having an unintended birth is strongly associated with the likelihood of having later unintended births. We use detailed longitudinal data from the Add Health Study (N = 8300) to investigate whether a host of measured sociodemographic, personality, and psychosocial characteristics select women into this “trajectory” of unintended childbearing. While some measured characteristics and aspects of the unfolding life course are related to unintended childbearing, explicitly modeling these effects does not greatly attenuate the association of an unintended birth with a subsequent one. Next, we statistically control for unmeasured time-invariant covariates that affect all birth intervals, and again find that the association of an unintended birth with subsequent ones remains strong. This persistent, strong association may be the direct result of experiencing an earlier unintended birth. We propose several mechanisms that might explain this strong association.
