Breastfeeding up to two years of age or beyond and its influence on child growth and development: a systematic review

Early cessation of breastfeeding and the associated factors among mothers with children aged 2 to 3 years in rural Southern Ethiopia: a community-based cross-sectional study

BACKGROUND

Breast milk is the first natural food for babies. It has nutritional, immunological, developmental, psychological, societal and environmental advantages. Failing to feed children for twenty-four months has so many negative consequences to children. Though studies have well documented the duration of breast feeding in the first six months, the proportion of women completing the recommended duration and factors associated with it has not been well investigated in rural places of Ethiopia. Therefore, this study aims to fill this gap in evidence among mothers with children aged 2 to 3 years in Arba Minch Health and Demographic Surveillance Site in 2021 E.C.

METHODS

A community-based cross-sectional study was conducted in all kebeles of the surveillance site by employing multi-stage sampling technique. Descriptive statistics was done to summarize findings and binary logistics regression model was used to identify factors significantly associated with early breast-feeding cessation respectively. OR with its 95% CI was obtained to quantify the degree of association between explanatory variables and early breastfeeding cessation.

RESULT

The proportion of early cessations of breast feeding was 29.30% (25.02, 33.64%). Being from a household with no fathers 'education or primary education [AOR=0.22; 95%CI (0.07, 0.74)] and [AOR=0.30; 95%CI (0.12, 0.76)], farmer mothers [AOR=6.40; 95%CI: (1.38, 29.74)], birth interval of less than 2 years [AOR=2.07; 95%CI: (1.03, 4.16)], and with mothers' one or two to three antenatal care visits [AOR = 2.73; 95%CI: (1.27,5.88)] were factors significantly associated with early cessations of breast feeding.

CONCLUSION AND RECOMMENDATION

The proportion of early cessations of breast feeding was high. Father's education, being farmer, birth interval and ante natal care visit were significant factors. Health education about proper breast feeding practice and improving ante natal care attendance might improve premature cessation of breast feeding among women.

Predictors for the duration of breastfeeding among ethiopia women of childbearing age with babies; application of accelerate failure time and parametric shared frailty models

Introduction

Duration of breastfeeding is the length of the time that infants who were initially breastfed continue to receive breast milk until weaning. The duration of breastfeeding is important for a child's health, growth, and development. However, the duration of breastfeeding decreases from time to time and further leads children to be exposed to malnutrition (stunting, wasting, and weight loss). Children who did not get enough breastfeeding are also exposed to different diseases. Previous studies used a simple survival model and didn’t see the shared frailty model on the variable of interest. Therefore, the current study aimed to investigate the factors affecting the duration of breastfeeding among Ethiopian women of reproductive age with babies.

Methods

A cross-sectional study design was conducted on 15,400 women of childbearing age with babies in nine regional states and two city administrations. The data source for the analysis was the 2016 EDHS data. The Cox-proportional hazard model, AFT, and parametric shared frailty models were conducted for the current investigation. Weibull-gamma shared frailty model was in favor of others for current data analysis.

Results

Among the covariates, women living in urban area (Φ = 0.96; 95% CI; (0.94,0.97); p-value = 0.001), non-educated women(Φ = 1.03; 95% CI; (1.00,1.06); p-value = 0.039), primary educated women (Φ = 1.13; 95% CI; (1.11,1.15); p-value < 0.001), age of a child (Φ = 0.99; 95% CI; (0.76.0.99); p-value < 0.001) and non-smoker mothers (Φ = 1.60; 95% CI; (1.57, 1.63); p-value < 0.001),birth interval between 2–3 years(Φ = 1.02; 95% CI;(1.09, 1.25, p-value = 0.027), birth interval, > 3 years(Φ = 1.28; 95% CI; (1.06, 1.43); p-value < 0.01 significantly affected the duration of breastfeeding. The median survival time of breastfeeding of women of reproductive age with babies considered under study was 23.4 months. Clustering had a significant effect on the variable of interest.

Conclusion

Residence area, level of education, age of the child, smoking status of women, and birth interval of successive birth significantly affected the duration of breastfeeding in the current investigation. Hence, the health staff should conduct health-related education for young women, educated women, urban women, smoker women, and women with a shorter interval of birth to increase the women's attitude and awareness towards the use of long-duration of breastfeeding.

Prevalence of Infant and Young Child Feeding Practices and Differences in Estimates of Minimum Dietary Diversity Using 2008 and 2021 Definitions: Evidence from Bangladesh

Background

Infant and young child feeding (IYCF) practices directly impact the health of <2-y-old children. Minimum dietary diversity (MDD) is an IYCF indicator to assess feeding practices of children aged 6-23 mo. The definition of MDD has recently been updated by the WHO and UNICEF, substituting "≥4 out of 7 food groups" (MDD-7FG) with "≥5 out of 8 food groups" (MDD-8FG).

Objectives

The goals of this study were to estimate the prevalence of IYCF indicators and identify the implications of the change in the prevalence of MDD at the national and regional levels of Bangladesh.

Methods

This study used data from the National Food Security and Nutrition Surveillance 2018-2019 round. A total of 1992 children aged 0-23 mo were included in this analysis. IYCF indicators and MDD were calculated according to the WHO-UNICEF guidelines. The difference between the prevalence of MDD-7FG and MDD-8FG is presented as percentage points.

Results

The prevalence of early initiation of breastfeeding was 43.8%, and exclusive breastfeeding was 56.2%. Approximately 55% of children maintained MDD (MDD-7FG), 48% received minimum meal frequency, and 28% received a minimum acceptable diet. Compared with MDD-7FG, the prevalence of MDD-8FG was lower among 6-23-mo-old children. The difference between MDD prevalence (MDD-8FG vs. MDD-7FG) was high for boys (44.0% vs. 53.2%), children aged 12-23 mo (53.4% vs. 63.4%), in urban areas (30.2% vs. 42.4%), in the Dhaka administrative division (42.0% vs. 56.3%), among uneducated mothers (37.1% vs. 47.1%), in households with ≤4 members (44.3% vs. 55%), and for middle-class households (40.3% vs. 57.6%).

Conclusions

The new method led to a decrease in the prevalence of MDD in Bangladesh. As the country prepares to implement the new indicator, it is critical to disseminate the new knowledge and its positive implication for improved child feeding and nutrition.

Breastfeeding Beyond 12 Months: Is There Evidence for Health Impacts?

Because breastfeeding provides optimal nutrition and other benefits for infants (e.g., lower risk of infectious disease) and benefits for mothers (e.g., less postpartum bleeding), health organizations recommend that healthy infants be exclusively breastfed for 4 to 6 months in the United States and 6 months internationally. Recommendations related to how long breastfeeding should continue, however, are inconsistent. The objective of this article is to review the literature related to evidence for benefits of breastfeeding beyond 1 year for mothers and infants. In summary, human milk represents a good source of nutrients and immune components beyond 1 year. Some studies point toward lower infant mortality in undernourished children breastfed for >1 year, and prolonged breastfeeding increases interbirth intervals. Data on other outcomes (e.g., growth, diarrhea, obesity, and maternal weight loss) are inconsistent, often lacking sufficient control for confounding variables. There is a substantial need for rigorous, prospective, mixed-methods, cross-cultural research on this topic. Expected final online publication date for the Annual Review of Nutrition, Volume 41 is September 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Assessing the level of knowledge and practice of breastfeeding among factory working mothers in Kathmandu, Nepal

Purpose

The purpose of this paper is to assess the level of knowledge and practice of breastfeeding among factory working mothers in Kathmandu who had a minimum of one child of less than two years of age.

Design/methodology/approach

A cross-sectional survey, with the help of a semi-structured questionnaire, was completed. χ2 or Fisher exact tests were applied for analysis using the SPSS program.

Findings

In total, 36.0 percent of the mothers had adequate knowledge, and 40.0 percent had an appropriate practice of breastfeeding (BF). Also, 30 percent of them were supplementing their BF with additional milk and 54.0 percent began to give additional food at less than six months of age, mainly due to insufficient breast milk. However, 40.0 percent of mothers practiced exclusive BF; 34.0 percent of mothers continued BF until their child reached two years of age. BF was initiated within an hour by 64.0 percent of mothers. Regarding knowledge, the majority of them (82 percent) knew about initiation time of the feed, 64.0 percent of mothers knew that breast milk had positive effects on a child’s health while 48.0 percent knew that it also had good effects on the mothers’ health. There was a positive association between available facilities and BF knowledge levels (p-value<0.00, χ2=4.25, df=1). The associations of knowledge levels against the education status of mothers (p-value=0.11, χ2=2.59, df=1) and practice level of initiation of breast milk (p-value=0.96, χ2=0.02, df=1) were not significant.

Originality/value

The knowledge and practices of BF among factory working mothers are not satisfactory. Hence, an effective way to encourage BF is to increase the availability of facilities for the practice of BF at a mother’s workplace.

Variation in the Protein Composition of Human Milk during Extended Lactation: A Narrative Review

The aim of this review is to evaluate changes in protein parameters in the second year postpartum. There is considerable agreement among authors about the declining trend of human milk protein concentrations, but most research on protein content in breast milk focuses on the first year of life and comes from developed countries. Whereas this is the case for exclusive breastfeeding or for breastfeeding into the first year of life, the opposite applies to weaning or extended breastfeeding. This review is predominantly based on observational epidemiological evidence and on comparative research linking breast milk composition with cutting down on breastfeeding. Studies dating back several decades have shown an increase in the proportion of immunoglobulins, lactoferrin, and serum albumin during weaning. According to the limited data available, it seems likely that the regulation of milk protein composition during involution can be ascribed to alterations in tight junctions. In studies on humans and other mammalian species, offspring suckle more from mothers that produce more dilute milk and the increase in milk protein concentration is positively correlated to a decrease in suckling frequency during weaning. High milk protein contents were first reported in nonindustrial communities where breastfeeding is sustained the longest, but recent papers from urbanized communities have taken credit for rediscovering the increase in protein content of human milk that becomes evident with prolonged breastfeeding. This review presents an overview of the changes in breast milk protein parameters in the second year postpartum to enable milk banks' practitioners to make informed nutritional decisions on preterm infants.

Determinants of Stunting, Wasting, and Anemia in Guinean Preschool-Age Children: An Analysis of DHS Data From 1999, 2005, and 2012

Wasting, stunting, and anemia are persistent and important forms of malnutrition in preschool-age children in the less developed world, in particular the Republic of Guinea, which was the site of a large outbreak of Ebola virus disease in 2014 to 2015. We analyzed data from 3 Demographic and Health Surveys done in Guinea in 1999, 2005, and 2012 to identify possible determinants of wasting, stunting, and anemia. All analyses, both bivariate and multivariate, were carried out separately for each of 3 age groups: less than 6 months, 6 to 23 months, and 24 to 59 months. Variables found statistically significantly associated with stunting, wasting, or anemia in bivariate analysis were placed in an age-specific logistic regression model for that outcome. Overall, anthropometric indices were available for 9228 children and hemoglobin concentrations were available for 5681 children. Logistic regression found relatively few variables associated with nutrition outcomes in children younger than 6 months. More variables were associated with nutrition outcomes in children aged 6 to 23 months. Such variables measured a wide variety of conditions, including estimated birth size, child health and nutritional status, child caring practices, mother's nutritional and health status, and household water source and sanitation. A similarly broad range of variables was statistically significantly associated with one or more nutrition outcomes in children aged 24 to 59 months. Few of the standard infant and young child feeding indicators were associated with any nutrition outcome. Improvement in the nutritional status of young children in Guinea may require a broad range of nutrition and health interventions.

Breastfeeding and Oral Health: Evidence and Methodological Challenges

Breastfeeding is a powerful health-promoting behavior. A 2016 Lancet global collaboration to review the health implications of breastfeeding was among the first to consider oral health outcomes. While a role was suggested for breastfeeding in preventing malocclusion, caries was the only included disease condition unfavorably associated with breastfeeding. The present critical review examines the evidence connecting breastfeeding practices to these outcomes and discusses the methodological challenges inherent in reaching causal conclusions. Published systematic reviews show some evidence of a protective effect of breastfeeding against primary dentition malocclusion but no supportive evidence for mixed dentition and permanent dentition malocclusions. Regarding caries, well-conducted studies report a benefit with breastfeeding up to 12 mo but a positive association between caries and breastfeeding of longer duration, at times that vary between 12 and 24 mo, as well as nocturnal feeding. Future studies would be methodologically stronger if focused on specific malocclusion traits that are plausibly associated with sucking movements rather than using general malocclusion indices. Studies should use detailed and consistent terminology for breastfeeding definition, including frequency, intensity, and timing. Analytical studies should be carried out to distinguish between confounders (e.g., prematurity) and mediators (e.g., use of pacifier). Regarding a link to caries, standard terminology for exposures (e.g., nocturnal feeding) is recommended. Statistical analyses must account for known confounding factors (e.g., socioeconomic conditions) but avoid inappropriate adjustment for variables on a causal path between exposure and outcome or for variables not associated with breastfeeding (e.g., tooth brushing), as can be guided using tools such as direct acyclic graphs. For dental practice, the potential caries risk of long-duration breastfeeding should be part of individual patient counseling that incorporates patient values and circumstances. Given the unquestioned overall health benefits of breastfeeding, the dental community should support World Health Organization guidelines that encourage and promote breastfeeding.

Prolonged breastfeeding for 24 months or more and mental health at 6 years of age: evidence from the 2004 Pelotas Birth Cohort Study, Brazil

BACKGROUND

There is scarce and conflicting evidence on medium- to long-term effects of prolonged breastfeeding on child behavior.

METHOD

A population-based birth cohort study started in 2004 in the city of Pelotas, Southern Brazil. Children were followed up at 3, 12, 24, and 48 months and 6 years of age. Breastfeeding duration was determined based on information collected around the time of weaning. Psychiatric disorders were assessed using the Development and Well-Being Assessment (DAWBA). Children who were never breastfed were excluded from the analysis. Crude and adjusted analyses were performed using Poisson regression with robust variance.

RESULTS

Data on breastfeeding and mental health at the age of 6 years were available for 3377 children. Prevalence of breastfeeding for 24-35 months and ≥36 months was 16.1% (95% CI: 14.8-17.3) and 8.1% (95% CI: 7.2-9.1), respectively. Prevalence of psychiatric disorders among those who were breastfed for <24 months, 24-35 months and ≥36 months was 12.4% (95% CI: 11.1-13.7), 13.1% (95% CI: 10.4-16.2) and 12.3% (95% CI: 8.7-16.8), respectively. No association was found between breastfeeding for 24 months or more and psychiatric disorders among children aged 6 years both in the crude and adjusted analyses.

CONCLUSIONS

In this cohort there was no association between breastfeeding for 24 months or more and an increased prevalence of psychiatric disorders at the age of 6 years. Studies analyzing the medium- and long-term effects of prolonged breastfeeding for 2 years or more are scarce and further research is needed regarding this practice.

Nutrition (Micronutrients) in Child Growth and Development: A Systematic Review on Current Evidence, Recommendations and Opportunities for Further Research

OBJECTIVE

An important aspect of malnutrition is deficiency of different micronutrients during pregnancy or early childhood. We systematically reviewed the role of nutrition in child growth (weight or height gain) and development.

METHODS

A comprehensive literature search was done on PubMed/Cochrane Library browsing through 38,795 abstracts until December 31, 2016 to select systematic reviews/meta-analyses and individual randomized controlled trials (RCTs) of micronutrient supplementation.

RESULTS

Micronutrients studied included iron, iodine, folate, zinc, calcium, magnesium, selenium, vitamin D, vitamin A, vitamin B complex, and multiple micronutrients. We summarize evidence with details and results of RCTs, highlight strengths/weaknesses, and critically interpret findings. Effects of breastfeeding-promotion, food-supplementation (complementary and school feeding), conditional-cash-transfers, and integrated nutrition/psychosocial interventions are discussed.

CONCLUSION

Based on this evidence we make policy and programmatic recommendations for supplementation to mothers and children at high-risk of deficiency.

Factors Associated With Extended Breastfeeding in India

BACKGROUND

Extended breastfeeding duration is common in India. Extended breastfeeding protects the infant from infectious disease and promotes child spacing. In the 1990s, the median breastfeeding duration in India was 24 months. Research aim: This study aimed to investigate the median duration of breastfeeding in India and to identify the factors associated with extended breastfeeding to 24 months as recommended by the World Health Organization.

METHODS

This cross-sectional data analysis used nationally representative data from the 2011-2012 Indian Human Development Survey II. The outcome in this study was extended breastfeeding defined as breastfeeding to 24 months or more. Multivariate logistic regression was used to identify the factors associated with extended breastfeeding.

RESULTS

The median duration of breastfeeding was 12 months; approximately 25% of women breastfed 24 months or more. Women were at greater odds of breastfeeding 24 months or more if the infant was a boy compared with a girl, if the women lived in a rural area compared with an urban area, if the women were married at a young age (< 17 vs. 20 years or older at marriage), and if the delivery was assisted by a friend or relative compared with a doctor.

CONCLUSION

The median duration of breastfeeding has decreased by 50% from 1992-1993 to 2011-2012. The women who continue to breastfeed 24 months or more tend to be more traditional (i.e., living in rural areas, marrying young, and having family/friends as birth attendants). Further research to study the health effect of decreased breastfeeding duration is warranted.
