Maternal age and maternal Raven score were positively associated
with duration of breast feeding (table 1).

A longer
duration of breastfeeding — for example more than 12 months (and this can be over several babies) is more protective, even if you are breastfeeding at all and whether you are mixed
feeding with some
breast milk and some formula, your
breast cancer risks are reduced.
Breastfeeding is also associated
with maternal health outcomes.5 Shorter
duration of lactation is associated
with increased maternal
breast cancer, 6 ovarian cancer, 7,8 hypertension, 9 — 11 type 2 diabetes mellitus, 9,12 and myocardial infarction (MI).9, 13 We estimate the burden
of maternal disease that might be averted if more mothers were able to adhere to infant
feeding recommendations, assuming a causal association between breastfeeding and maternal health.
Breastfeeding is an unequalled way
of providing ideal food for the healthy growth and development
of infants1, providing protection from morbidity and mortality due to infectious diseases2 and chronic diseases later in life.3 Exclusive breastfeeding is recommended, starting within one hour
of birth and for the first 6 months
of life,
with continued breastfeeding to 2 years
of age and beyond.4 However, rates
of initiation, exclusive breastfeeding and breastfeeding
duration have fallen since the widespread introduction and promotion
of breast - milk substitutes.5 Successful breastfeeding depends on a number
of factors, including a re-normalisation
of breastfeeding as the infant
feeding method
of choice through antenatal counselling and education and breastfeeding support to prevent and resolve breastfeeding difficulties.
Some mums find latching on more successful if they lean forwards slightly to bring the
breast up to baby's mouth, and many need to hold their
breast up
with one hand for the
duration of the
feed.
The intake
of such supplementary fluids is associated in young infants
with an increased risk
of disease and a shortening
of the
duration of breast -
feeding.
Secondary outcomes included the proportion
of women giving any
breast feeds, or bottle
feeds at 4 months, the
duration of any breastfeeding, time to introduction
of bottle
feeds, and satisfaction
with breastfeeding at 6 weeks.
Months since
breast feeding cessation and
duration of breast feeding were both significantly associated
with diarrhoeal disease, but much
of these effects were due to the inclusion
of the currently
breast fed and never
breast fed infants; neither was statistically significant when these infants were omitted.
There was no evidence
of a dose - response effect for
breast feeding duration but there was for time since
breast feeding cessation,
with the protective effect
of breast feeding not persisting long after
breast feeding had stopped.
Ludvigsson et al (32) examined 8300 infants and demonstrated that the
duration of exclusive
breast -
feeding was not associated
with a lower risk
of atopic dermatitis, even among infants
with a family history
of atopy.
While antenatal education and counselling is helpful, 8 68 %
of mothers said that early problems
with breast feeding was the main reason they stopped nursing before two months postpartum.7 Other barriers were lack
of knowledge about
breast feeding and lack
of support from health professionals.7 Women value being shown how to
breast feed rather than being told how to.9 10 Evidence
of effective interventions to improve exclusive
breast feeding for the recommended
duration of six months is sparse.
A randomised trial in Brazil that compared a hospital based protocol (similar to the baby friendly hospital initiative)
with another incorporating intensive home visits, however, found that while the protocol achieved high rates
of exclusive
breast feeding in hospital, the rates fell rapidly thereafter.27 These findings were confirmed in the UK by the millennium cohort study, 5 and the authors recommended that the baby friendly hospital initiative as a strategy for promotion
of breast feeding should be reassessed and that other strategies are required to support mothers in the UK to
breast feed for the recommended
duration.5 27 Although combined antenatal education and postnatal support is ideal, this may be limited by economic or time resources.
The recent NICE evidence into practice briefing on promotion
of initiation and
duration of breast feeding, 4 however, recommended that education and support should be targeted at women
with low incomes to increase rates
of exclusive
breast feeding.
Instead we found that a shorter
duration of breast feeding was associated
with lower scores on mental developmental tests both at 13 months and at 5 years
of age.
The psychomotor index did not differ significantly between the groups (p = 0.09), although there was a trend (p < 0.05) towards increasing scores
with increasing
duration of breast feeding.
The consultation recommended exclusive
breast feeding for six months,
with introduction
of complementary foods and continued
breast feeding thereafter.19 Given this recommendation, it is important that the role
of exclusive, predominant, or any
breast feeding duration in the prevention
of childhood illness and infection is properly quantified and acknowledged.
Most previous studies have compared
breast fed children
with children who were exclusively formula
fed, but some studies have found that the correlation between
breast feeding and cognitive ability increases
with a longer
duration of breast feeding.3 13 30 A Finnish study
of 1163 children found a mean difference
of 2.4 points on a cognitive test at 6 months
of age between children
breast fed for less than five months, compared to children
breast fed for at least five months.10
There was a borderline statistically significant difference in balance scores associated
with different lengths
of breast feeding, whereas no association was found between
duration of breast feeding and the two other motor development tests.
Moreover, although this reduced the power
of the multivariate analysis, the increased risk
of low MDI and total IQ scores associated
with a shorter
duration of breast feeding persisted after adjustment for each
of the confounders, including the Raven score.
We aimed to document the association
of duration of predominant
feeding and
duration of any
breast feeding with respiratory illness and infection morbidity as measured by doctor, hospital, or clinic visits and hospital admissions in the first year
of life.
Breast -
feeding for the same
duration lowered the risk
of the syndrome by 44 percent in women
with gestational diabetes.
