Sentences with phrase «duration of exclusive breastfeeding in»

[Effect of the baby friendly hospital initiative on the duration of exclusive breastfeeding in Kinshasa: a cluster randomized trial]

Our main exposures were the following: (1) duration of any breastfeeding in months; (2) duration of exclusive breastfeeding in months, defined as feeding breast milk but no solid foods or non — breast milk liquids (except water) to age 6 months; and (3) breastfeeding status at age 6 months, categorized as «formula only, never breast fed,» «formula only, weaned,» «mixed formula and breast milk,» and «breast milk only, no formula.»

In determining the optimal duration of exclusive breastfeeding in specific contexts, it is important that functional outcomes, e.g. infant morbidity and mortality, also are taken into consideration.

Maternal and perinatal factors influencing duration of exclusive breastfeeding in the first 6 months of life

Purpose: The purpose of this project was to determine if supplementing pregnant and lactating women with DHA and extending the duration of exclusive breastfeeding through the first year of life will improve neurological development in infants.

Longer duration of exclusive breastfeeding is especially important in countries where clean water, healthy food and healthcare are more of an issue, but ALL babies benefit the longer that mom continues to provide her milk.

The Lullaby Trust's Lucy Lyus, Research and Information Manager said in response to the study: «We recommend that women breastfeed their babies, if they can, as breastfeeding for any duration, whether exclusive or in combination with formula feeding, has been found to reduce the chance of Sudden Infant Death Syndrome (SIDS).

Our use of observational data reflects the existing literature on lactation and maternal health; apart from a single randomized trial examining the effect of exclusive lactation duration on maternal weight loss, 48 there are no published studies of maternal health outcomes in randomized trials of breastfeeding.

Most studies have revealed protective effects of breastfeeding on common infections in the first 8 to12 months of life.8, 27,29,30 One study, which distinguished between infectious diseases until and from the age of 6 months, revealed results similar to those from our study.24 Although the authors used exclusive breastfeeding for 3 months as the reference group, exclusive breastfeeding for 6 months reduced the risk of gastrointestinal tract infections between the ages of 3 and 6 months but not between the ages of 6 and 12 months.24 We can not explain why breastfeeding duration was only associated with lower risks of lower respiratory tract infection from 7 to 12 months.

However, the organization also called for more research regarding the benefits of 6 vs 4 months of exclusive breastfeeding.25 Thus far, several studies in industrialized countries revealed that a shorter duration of breastfeeding increases the risk of common infectious diseases, such as respiratory and gastrointestinal tract infections.8, 19,24,26, — , 32 However, in these studies, various definitions of the exclusiveness of breastfeeding were used24, 27,28,30 or the combination of duration and exclusiveness of breastfeeding was not taken into account.8, 31

Although not directly comparable, our findings are in broad agreement with those from routine data in Scotland that have indicated a positive association between Baby Friendly accreditation, but not certification, and breastfeeding at 1 week of age.17 Our findings reinforce those of Coutinho and colleagues who reported that high exclusive breastfeeding rates achieved in Brazilian hospitals implementing staff training with the course content of the Baby Friendly Hospital Initiative were short -

BFHI has been shown to be very effective in increasing breastfeeding initiation, exclusive breastfeeding and breastfeeding duration in many countries, as well as improving mother's health care experiences and reducing rates of infant abandonment.12 Given the short and long - term benefits of breastfeeding to the infant, mother and society, implementing BFHI — alongside with the other objectives stated in the Global Strategy for Infant and Young Child Feeding - continues to have an important role to play in health services worldwide.

In particular, breastfeeding may be of concern because it has been shown to be associated with both child's use of antibiotics36, 37 and cow's milk allergy, although inconsistently so.38 In a large Finnish birth cohort, the median durations of exclusive and total breastfeeding were 1.4 months and 7.0 months, respectively, and the proportion of breastfed infants decreased from 95 % at the age of 1 month to 58 % at the age of 6 months.39 Another limitation is our reliance on pharmacy records, which provides only a rough estimation of drug use.

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 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 diffExclusive 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 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 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 diffexclusive 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 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 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 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 breastfeeding as the infant feeding method of choice through antenatal counselling and education and breastfeeding support to prevent and resolve breastfeeding breastfeeding support to prevent and resolve breastfeeding breastfeeding difficulties.

The second measure was duration in months of exclusive breastfeeding.

In particular, there were significant adjusted associations between duration of exclusive breastfeeding and high school outcomes measured at age 18.

Bennis, A., Laamiri, F.Z., Chebguiti, A.A., Aguenaou, H., Mrabet, M., Kharbach, A. and Barkat, A. (2017) Impact of Educational Materials on the Duration of Exclusive Breastfeeding Assured by Women Who Delivered at the Souissi Maternity Hospital in Rabat.

An expert consultation was convened to review the scientific evidence on the optimal duration of exclusive breastfeeding, formulate recommendation for practice on the optimal duration of exclusive breastfeeding and develop recommendation for research need in this area.

There is some evidence that breastfeeding education and peer and professional support can increase the initiation of breastfeeding (Balogun 2016), and there is good evidence that support interventions by professionals or peers are effective in increasing the duration of any and exclusive breastfeeding for mothers of healthy term singletons (McFadden 2017).

This review is one in a series of Cochrane reviews examining education and support interventions to promote the initiation of breastfeeding and to increase the duration of breastfeeding and exclusive breastfeeding (Balogun 2016; Lumbiganon 2016; McFadden 2017).

In 2012, the Cochrane study (52 studies, 56,451 mother - infant pairs, 21 countries) found that postnatal support increases both the duration of breastfeeding and exclusive breastfeeding [17].

The duration of exclusive breastfeeding was 7.58 days (SD 8.32, n = 6) compared with 33.14 days (SD 66.51, n = 7) in the control group.

Although there were no important differences in breastfeeding duration between groups, there was a considerably longer duration of exclusive breastfeeding (which was defined as providing only breast milk for the previous 24 h, but did allow formula less than once per week) among women receiving the research bags (either alone or in combination with the research counseling [P < 0.01, 1 - tailed log rank test]-RRB- versus those not receiving research bags.

Although professional lactation support can improve the duration of overall breast feeding, its effect in improving exclusive breast feeding is unclear.11 18 22 Thus far, studies that report improvement of rates of exclusive breastfeeding have involved mainly community based peer counselling strategies.23 24 25 Even then, a randomised trial in the UK recently cast doubt on the efficacy of this approach.26 There are current recommendations from NICE for the UK - wide implementation of the baby friendly initiative.4 5 6 The 2006 NICE costing report on routine postnatal care of women and their babies estimates that efforts to improve rates of breast feeding will result in substantial cost savings for the NHS.6

Approximately one - third of mothers in our analysis strongly valued exclusive breastfeeding, even though they have established intention to exclusively breastfeed; unfortunately, many of them still could not attain the recommended duration of breastfeeding.

Reasons for this slow improvement among mothers in the United States include: (a) breastfeeding has not received sufficient national attention as a public health issue [5]; (b) inadequate attention to the importance of the duration of exclusive breastfeeding [3, 6]; and (c) inadequate research addressing exclusive breastfeeding in the United States [3, 7].

In addition, mothers who are educated about the benefits of exclusive breastfeeding are more likely to value exclusive breastfeeding and may be more determined to breastfeed for longer durations [15, 26].

Investing in programs that focus on maternal education of exclusive breastfeeding benefits would help mothers attain their breastfeeding goals and / or the expert recommended exclusive breastfeeding durations.

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

Fourth, higher quality maternal interactions have been shown to improve brain development at 5, 10 and 24 months.34 Fifth, there is growing evidence to suggest that the beneficial effects of exclusive breastfeeding may be moderated by the infant's genome, 35,36 and the metabolism of the fatty acids in maternal breast milk.37 For example, Krol et al. 36 showed that infants exclusively breastfed for a longer duration (above the 50th percentile) showed a heightened sensitivity and interest in a happy visual stimulus (eyes) than infants exclusively breastfed for a shorter duration (below the 50th percentile).

The relatively long duration of exclusive and any breastfeeding by the participants in the DNBC permitted us to construct statistically adequate prediction models of the potential contribution of breastfeeding to the reduction of PPWR.

Measured the duration of any and exclusive breastfeeding as the age of the infant in weeks when the participant completely stopped breastfeeding and first introduced infant formula, respectively.

The latest systematic review of the evidence on this issue was published in 2009 («Optimal duration of exclusive breastfeeding (Review)», Kramer MS, Kakuma R.

We found little evidence that between - study heterogeneity in estimates was explained by age at measurement of blood pressure (p = 0.5), decade of birth (p = 0.2), stipulation of a minimum duration of breastfeeding (p = 0.5), proportion of the target population in the main analysis (p = 0.2), whether breastfeeding was exclusive for at least 2 months (p = 0.2), method of blood pressure measurement (p = 0.4), or whether effect estimates controlled for socioeconomic factors (p = 0.9), maternal factors in pregnancy (p = 0.9), or current weight (p = 0.9).
