The Copenhagen cohort study on infant nutrition and growth:
duration of breast feeding and influencing factors.
We found no clear association between

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.
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.
The only factor in this study, related to
duration of breast feeding, which was also related to child development at 13 months, was maternal Raven score (data not shown).
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.
Duration of breast feeding was classified into three categories based on whether the child was still breast fed at 3 or 6 months of age.
Aim: To examine the relation between
the duration of breast feeding and morbidity as a result of respiratory illness and infection in the first year of life.
Maternal age and maternal Raven score were positively associated with
duration of breast feeding (table 1).
Under these otherwise favourable environmental conditions it may be questioned whether
duration of breast feeding has any effect on cognitive development.
Multivariate relation between upper respiratory infections at 1 year of age (hospital, doctor, or clinic visits, and hospital admission) and
duration of breast feeding
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

duration of 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.
Moreover, information on breast feeding was given prospectively and the examiners did not know
the duration of breast feeding, nor were they aware of the hypothesis.
While there is evidence for the effectiveness of professional support in prolonging
duration of breast feeding and increasing rates of initiation of breast feeding, the strength of its effect on the rate of exclusive breastfeeding is unclear.11 12
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.

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.
If the goal is prolonging the exclusivity and
duration of breast - feeding, according to Dr. Michael Kramer, a professor of pediatrics, epidemiology, and biostatistics at McGill University, some of the 10 steps are sounder than others.
