  • LANCET BREASTFEEDING SERIES 2016

On 29th Jan the Lancet published a new Series on Breastfeeding (http://www.thelancet.com/series/breastfeeding). It presented new evidence on the health and economic benefits of breastfeeding. The Key conclusion is “Not breastfeeding is associated with lower intelligence and economic losses of about $302 Billion annually, or 0.49% of world Gross National Income. Breastfeeding provides short-term and long-term health, economic and environment advantages to children, women, and society". According to the Lancet report breastfeeding could save 820,000 lives annually, i.e. preventing 13% of all deaths of children under five. Breastfeeding could reduce one third of respiratory infections and about half of all diarrhea episodes in low- and middle-income countries. The report says children who are breastfed longer have been found to have higher intelligence than those who are breastfed for shorter periods. This crucial difference could be  3 points across all income levels, in rich or poor, on average. Studies have shown this translates to improved academic performance, increased long term earnings and productivity as well.

  • What science tells us about the risks when children are not breastfed 

Breastfeeding as the norm for infant and young child feeding 
Since time immemorial the human species has been fed and nurtured by mother’s milk. As the normal continuum from pregnancy, through birthing, breastfeeding is the bond that sustains the mother baby relationship and provides the perfect nutrition, immunological protection and optimal physical and neurological development for the first years of life.

Scientific research has shown us the critical importance of breastfeeding. It is irreplaceable as the way to feed children.. Its intricate composition to both protect and nourish; its capacity to perfectly match growth and development needs make it an irreplaceable way to feed babies. Breastfeeding is vital for child survival and also important for mothers’ health. Breastfeeding contributes positively to the nation’s economy, to employers, families and communities. Below readers will find basic information about the importance of breastfeeding.

Breastfeeding is important for Children
Before a baby is born, the uterus protects him or her against most of the germs to which the mother is exposed. After birth, the mother’s breastmilk continues to protect against many of the viruses, bacteria and parasites to which the baby is now exposed. Several substances in breastmilk not only prevent diseases;
some stimulate and strengthen the development of the baby’s immature immune system. This results in better health, even years after breastfeeding has ended. For these and other reasons, based on scientific evidence, the World Health Assembly has adopted, as a public health recommendation, that babies should be fed exclusively on breastmilk for six months and continue breastfeeding at least until two years of age (1).

Breastfeeding promotes child survival:

  • If all babies were fed only breastmilk for the first six months of life, the lives of an estimated 1.5 million infants would be saved every year and the health and development of millions of others would be greatly improved,” states UNICEF in its 2002 edition of Facts for Life (2).
  • In resource-poor settings, exclusive breastfeeding may be the best option for HIV-positive mothers (3). This is confirmed by the November 2006 WHO Consensus Statement on HIV and Infant Feeding. http://www.who.int
  • Breastfeeding is an essential means of providing food security for millions of infants worldwide (4),
  • and even more so in developing countries and in regions having to cope with war, conflict, population displacement, natural disasters, or economic crises.
  • Bhutta et al. study shows how breastfeeding initiation immediately after birth is one of the more effectiven interventions. Read full article

Breastfeeding protects against infectious diseases:

  • Otitis media: Middle ear infections are one of the most frequent reasons for seeing the doctor. In a US study, infants from birth to twelve months who were not breastfed had twice as many ear infections as babies who were exclusively breastfed for about four months (5).
  • Diarrhoea: The antibodies in a mother’s milk protect her baby from the germs causing diarrhoea. In poor communities, diarrhoea caused by bottle-feeding is responsible for acute sickness. The cycle of illness, dehydration and malnutrition weakens the child, often fatally. A study from the Republic of Belarus
    shows that infants exclusively breastfeeding at three months have 40% less risk of developing gastrointestinal infections (6).
  • Pneumonia: Worldwide, pneumonia is one of the leading causes of death in children under five years of age. A study in Brazil showed that the risk of hospitalization for pneumonia among non-breastfed
    infants was 17 times greater than that for breastfed infants (7).

Breastfeeding  protects against asthma and other allergies:

  • In Australia, risk of childhood asthma decreases by at least 40% in infants breastfed for four months(8).
  • A Medline review of twelve studies relating breastfeeding and asthma points out that exclusive breastfeeding reduced the risk of asthma by 30%, and showed still better results (48%) in families with a history of asthma-related illnesses (9).

Breastfeeding confers optimal cognitive, linguistic and motor development:

  • In Denmark a recent study confirmed that breastfeeding affected brain development as measured
    in the child’s ability to crawl, to grip and to babble in polysyllables: the longer the duration of breastfeeding, the higher the child’s capacities (10).

Long-term importance of breastfeeding on health:

  • Bone mass: In Tanzania, a study demonstrated that there was significant association between breastfeeding in infancy and higher bone mineral density among the eight year-old boys examined, in comparison with children that had not been breastfed (11).
  • Haemophilus influenzae meningitis: In Sweden a study showed that low breastfeeding rates were followed, five to ten years later, by increased meningitis rates (12).
  • Obesity: In a number of countries (Germany, Czech Republic, the UK, the USA) research demonstrates that breastfeeding reduces the risk of obesity and overweight (13) (14).

Breastfeeding  is important for Mothers
Breastfeeding is an integral part of the reproductive cycle: exclusive breastfeeding, followed at six months by the introduction of appropriate complementary foods. Continued breastfeeding until the age of two years or more brings the reproductive cycle full circle. Studies have shown that there are many women for whom contraception is unavailable, unaffordable or unacceptable. For these women, breastfeeding (according to the LAM criteria mentioned below) is the primary means of delaying pregnancy and spacing births. Moreover, breastfeeding develops emotional and psychological well-being in mothers, and has numerous health advantages.

Breastfeeding provides child-spacing (LAM):

  • As long as a mother breastfeeds fully or nearly fully and as long as her periods have not returned, her protection against pregnancy during the first six months is 98 % (15). This family planning method is called the Lactational Amenorrhea Method - LAM.

Breastfeeding results in the reduction of anaemia:

  • In the first hours and days after birth, early breastfeeding brings about uterine contractions, preventing excessive blood loss.
  • Over the following months, breastfeeding reduces the frequency and severity of anaemia by delaying the return of monthly periods and helping the mother build her iron reserves (16).

Long-term importance of breastfeeding on mothers’ health (17):

  • Breast cancer: Studies from the US, China, Japan, New Zealand, the UK and Mexico show that women who breastfed their children have reduced risk of developing breast cancer and that the risk declines with increased duration of breastfeeding (18).
  • Ovarian cancer: Breastfeeding for at least two months per child decreases the mother’s risk of developing epithelial ovarian cancer (19).
  • Osteoporosis:  The risk of hip fracture amongst women over 65 is reduced by half for those who have breastfed. It decreases by another quarter for those who have breastfed each of their children at least nine months (20) (21).

Importance for Families
Preparing for the arrival of the new baby, undergoing the birth process, and adapting to the child’s first
months are among the most extraordinary, testing, and emotional periods that parents and families experience. Loving, caring for, nurturing, but also worrying about one’s child are normal feelings and are sometimes overwhelming. Any illness takes an emotional toll on families; sickness in a newborn baby or a working mother causes even more worry. Health care costs are constantly increasing and can represent considerable strain on the family budget.

Breastfeeding strengthens family ties:

  • Studies have shown the emotional and psychological importance, as well as the bonding effects of breastfeeding to both mother and child. The importance of bonding is even greater when mothers return to work (22).
  • Breastfeeding develops a mother’s confidence in her physical and emotional capacities (23).

Breastfeeding saves money and time:

  • Saving of time because there is no need to go out to buy breastmilk substitutes or other goods.
  • Savings on the purchase of breastmilk substitutes and other feeding equipment.
  • Formula feeding increases costs for medical care and medication.
  • Formula feeding increases costs for child spacing and birth control methods.
  • Less time preparing bottles, including fetching water, fuel, and cleaning utensils.
  • Less time and worry spent on having to care for illnesses that could often be avoided.

Importance for Employers
When infants and children are sick, mothers or fathers often stay home to care for them. National laws may allow parents to take holiday leave or to call in sick themselves. This absenteeism is costly to employers – and to national budgets for health care. Moreover, many employed women have only a short period of paid maternity leave. If they want to breastfeed their babies, it is important to set up favourable conditions at the workplace. Many labour laws provide paid or unpaid daily breastfeeding breaks, and many employers set up breastfeeding facilities on-site for their female workers. Adequate hygienic facilities for breastfeeding or expressing and storing breastmilk are relatively easy and inexpensive to provide.

Formula feeding increases staff absenteeism:

  • Studies in the USA and elsewhere have shown that breastfed babies had statistically fewer episodes of illness than formula-fed infants and that mothers of breastfed babies were less absent (only 25% of one-day maternal absences) than mothers of bottle-fed babies (24).

Breastfeeding contributes towards a more stable workforce:
Employers who support their female employees (maternity benefits, breastfeeding breaks, rest periods...) note improved staff morale, less turnover and increased loyalty to the enterprise.

Importance for Society
Breastmilk is a living substance. It is unique and irreplaceable, specifically tailored to the changing needs of each baby. It is the first human food par excellence, the best example of how humanity can sustain itself through provision of a complete food for human babies. Breastfeeding also makes economic sense because it is less costly to produce than formula; it also allows society to make considerable savings in health care costs.

Breastfeeding helps to protect the environment:

  • Environmentally-friendly in its production, consumption and disposal: breastfeeding is a natural and renewable resource.
  • Reduction in industrial production, transportation, packaging, and disposal pollution: breastfeeding produces hardly any waste.

Breastfeeding  has economic importance: 

  • Nations can save huge amounts on the purchase and distribution of commercial breastmilk substitutes (often in foreign exchange). In India for example, at the national level, women produce approximately 3,900 million litres of milk over a two-year period (which corresponds to the usual lactation period of Indian mothers). If the milk had been purchased in the form of tinned cow’s milk, it would have cost close to three billion dollars, or more than three times the combined budgets of the Departments of Education, Health and Family Welfare, and Science and Technology during that same period of time. In Guatemala, annual spending on breastmilk substitutes amounts to approximately 48 million dollars (25).
  • Savings on health care expenses for preventable acute and chronic illnesses: an Australian study calculated that if breastfeeding at three months of age increased in prevalence from 60% to 80%, Australian $3.7 million would be saved on treating gastro-intestinal diseases alone (26). Researchers in Newfoundland, Canada, estimated that improved prevalence of breastfeeding could save the province up to Canadian $370,000 per year on the care of babies with asthma and eczema (27).

Breastfeeding has a positive impact on society at every level, it is all the more important that the responsibility for protecting and promoting breastfeeding and for supporting women to optimally breastfeed is borne by society as a whole.

Moreover, concerning the very controversial subject of transmission of HIV/AIDS from mother to child through breastmilk, WHO and UNICEF recommend that as long as artificial feeding is not acceptable, feasible, affordable, sustainable and safe, HIV+ mothers should exclusively breastfeed for the first months of their baby’s life. And in
all cases, mothers should be sufficiently informed to be able to make an informed decision about the way they will feed their child.
