Longer Duration Of Breastfeeding Research Articles

New York State Paid Family Leave Law Associated with Increased Breastfeeding Among Black Women.

Background: While breastfeeding has increased during the past 50 years, disparities continue, with Black women having the lowest rates. Use of paid leave has been associated with longer breastfeeding duration. Objective: Evaluate the impact of New York (NY)'s Paid Family Leave (PFL) law on breastfeeding, after it became effective on January 1, 2018. Materials and Methods: Women in NY (excluding NY City), who gave birth in 2016-2019 and completed the Pregnancy Risk Assessment and Monitoring System (PRAMS) survey, were included. Data from PRAMS and the NY State Expanded Birth Certificate were combined. Changes in breastfeeding initiation and duration and use of paid leave were compared, before and after NY's PFL law became effective, with separate analysis by sociodemographic factors. Results: Before NYPFL, Black women were least likely to initiate breastfeeding and breastfed for the shortest duration. After NYPFL went into effect, breastfeeding initiation and duration to 8 weeks increased for Black women, but not for other racial/ethnic groups; these findings persisted after adjustment for sociodemographic factors. Use of paid leave after childbirth increased 15% overall, with greater increases among Black women and Hispanic women. Conclusions: Implementation of the NYPFL law was associated with increased breastfeeding among Black women and increased use of paid leave by all. Greater increases in breastfeeding among Black women significantly reduced breastfeeding disparities by race/ethnicity. More widespread implementation of PFL programs in the United States would promote equity in the use of paid leave, which could reduce disparities in breastfeeding initiation and duration and possibly improve infant and maternal health outcomes.

The Relationship between Breastfeeding and Initial Vegetable Introduction with Vegetable Consumption in a National Cohort of Children Ages 1-5 Years from Low-Income Households.

Compared to other food groups, vegetable intakes are lowest relative to recommendations. Breastfeeding and initial introduction to vegetables may help infants establish long-lasting taste preferences. We examined the relationship between breastfeeding and initial vegetable introduction and vegetable intake in early childhood (ages 13–60 months). This repeated cross-sectional study used data from the national WIC Infant and Toddler Feeding Practices Study-2 collected from low-income mother/caregivers about infants from around birth through age 5 (60 months; n = 3773). Survey-weighted adjusted regression models assessed associations between breastfeeding and vegetable introduction measures with vegetable consumption at child ages 13, 24, 36, 48, and 60 months. Longer breastfeeding duration was associated with a slightly, but significantly, greater variety of vegetables consumed/day in early childhood. There was also a small but positive statistically significant association between the number of different types of vegetables consumed on a given day at 9 months and the amount and variety of vegetables consumed/day in early childhood. Age of initial vegetables introduction and whether vegetables were the first/second food introduced were not consistently related to the amount or variety of vegetables consumed later in childhood. Longer breastfeeding and introduction to a greater variety of vegetables at 9 months may be behaviors to target to increase consumption of a greater variety of vegetables by young children.

Delayed secretory activation and low milk production in women with gestational diabetes: a case series

BackgroundGestational diabetes mellitus (GDM) is major pregnancy complication that is associated with short- and long-term consequences for both mother and infant, including increased risk of diabetes later in life. A longer breastfeeding duration has been associated with a reduced risk of diabetes, however, women with GDM are less likely to exclusively breastfeed and have shorter breastfeeding duration. While the timing of breastfeeding initiation and milk removal frequency affects subsequent breastfeeding outcomes, little is known about early infant feeding practices and milk production in women with GDM. This case series offers detailed prospective breastfeeding initiation data, as well as the first report of objective measures of milk production in women with GDM.Case presentationIn this case series, we present the early infant feeding practices of eight women with GDM that gave birth at term gestation. Women recorded the timing of initiation of breastfeeding and secretory activation, as well as their breastfeeding, expression and formula feeding frequencies on postpartum days 1, 7 and 21. Measurement of 24 h milk production volume was performed at 3 weeks postpartum using the test weight method. We observed a delayed first breastfeed (> 1 h) in 6 (75%) cases, formula use in hospital in 5 (63%) cases and delayed secretory activation in 3 (38%) cases. At 3 weeks postpartum, 2 cases had measured milk productions that were insufficient to sustain adequate infant weight gain.ConclusionsOur data suggest that despite early and frequent milk removal, women with GDM are at greater risk of delayed secretory activation and low milk supply. Cohort studies that consider co-morbidities such as obesity are needed to determine the lactation outcomes of women with GDM.

Predictors of Prenatal Breastfeeding Self-Efficacy in Expectant Mothers with Gestational Diabetes Mellitus.

Breastfeeding is beneficial for mothers with gestational diabetes mellitus (GDM). Saudi Arabia is considered one of the countries with the highest prevalence of GDM. Mothers with GDM have a low intention to breastfeed and are less likely to continue breastfeeding. This study aimed to measure breastfeeding self-efficacy among expectant mothers with GDM and quantify its determinants. This cross-sectional study recruited expectant mothers with GDM from an antenatal care clinic and queried them on breastfeeding knowledge and attitudes using the Arabic validated prenatal breastfeeding self-efficacy scale (PBSES). The study took place at the Medical City of King Saud University, during January–April 2021. The average PBSES score among 145 GDM Saudi participants was 64.07 ± 16.3. Higher academic level, previous satisfactory breastfeeding experiences, breastfeeding intention, six months or more breastfeeding experience, and health education were significantly positively correlated with PBSES score. A higher knowledge score was also correlated with a higher PBSES score (p = 0.002). Longer breastfeeding duration (β.197, p = 0.036), satisfactory previous breastfeeding experience (β.218, p = 0.020), and higher knowledge score (β.259, p = 0.004) were significant predictors of a high PBSES score. Breastfeeding self-efficacy is low among expectant Saudi mothers with GDM, especially those with unsatisfactory previous experience or low knowledge scores. Establishing systematic education about breastfeeding during antenatal care is recommended to improve breastfeeding experience and improve GDM outcomes.

Association of Breastfeeding Duration with 12-Month Postpartum Blood Lipids in a Predominately Lower-Income Hispanic Pregnancy Cohort in Los Angeles.

Breastfeeding may protect women’s long-term cardiovascular health; however, breastfeeding-related postpartum lipid changes remain unclear. We aim to examine associations of breastfeeding duration with maternal lipids at 12 months postpartum. In a subsample (n = 79) of the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) cohort, breastfeeding status and duration at 3, 6, and 12 months postpartum were self-reported. Serum levels of lipids, including total cholesterol, triglycerides (TG), high-, low-, and very low-density lipoprotein cholesterol (HDL-C, LDL-C, VLDL-C), were measured from blood samples collected at 12 months postpartum. We used linear regression models to compare lipids by breastfeeding duration, adjusting for potential confounders. Women who were breastfeeding at 12 months had higher HDL-C (mean: 41.74 mg/dL, 95% CI: 37.27–46.74 vs. 35.11 mg/dL, 95% CI: 31.42–39.24), lower TG (80.45 mg/dL, 95% CI: 66.20–97.77 vs. 119.11 mg/dL, 95% CI: 98.36–144.25), and lower VLDL-C (16.31 mg/dL, 95% CI: 13.23, 20.12 vs. 23.09 mg/dL, 95% CI: 18.61–28.65) compared to women who breastfed for <6 months. No lipids were significantly different between women who breastfed for 6–11 months and for <6 months. Each month’s increase in breastfeeding duration was significantly, inversely associated with TG and VLDL-C and positively with HDL-C. Adjusting for fasting status, demographics, pre-pregnancy body mass index, breastfeeding frequency, and pregnancy complications did not appreciably change effect estimates. Breastfeeding at 12 months postpartum and a longer duration of breastfeeding in the first year postpartum were both associated with increased HDL-C and decreased TG and VLDL-C at 12 months postpartum.

Prenatal and early childhood predictors of intelligence quotient (IQ) in 7-year-old Danish children from the Odense Child Cohort.

Cognitive development measured as intelligence quotient can predict socioeconomic markers in adulthood. It is therefore of interest to determine predictors of childhood intelligence quotient. To assess intelligence quotient scores based on standardised Danish age-appropriate scores and to evaluate potential predictors of intelligence quotient. At 7 years of age children in the Odense Child Cohort completed an abbreviated version of the Wechsler intelligence scale for children 5th edition consisting of four subtests (vocabulary, similarities, block design and matrix reasoning) from which the full scale intelligence quotient and verbal comprehension index were estimated. Potential predictors from pregnancy through childhood were collected from questionnaires, birth records and clinical examinations. Intelligence quotient scores were investigated through descriptive statistics and linear regression models. The mean full scale intelligence quotient among 1375 children was 99.1 (95% confidence interval 98.5; 99.8) points. Higher full scale intelligence quotient scores were observed in girls 100.8 (95% confidence interval 100.0; 101.8) compared to boys 97.6 (96.7; 98.4), and in children of mothers with high and intermediate education 101.7 (100.4; 103.1) and 99.6 (98.7; 100.5), respectively, compared to low education 96.1 (94.9; 97.3). In linear regression analyses, longer maternal education and child sex (girls) remained strong predictors of intelligence quotient at age 7 years. In addition, paternal education, child head circumference and longer duration of breastfeeding were associated with higher intelligence quotient, whereas maternal overweight and obesity before pregnancy was associated with lower intelligence quotient. Mean intelligence quotient scores were comparable to the standardised mean intelligence quotient of 100 point of Danish peers. It is important to follow up these children to determine which predictors persist into adulthood.

Reciprocal Associations Between Maternal Smoking Cessation and Breastfeeding.

Background: Pregnancy is a motivating factor to quit smoking, but many women relapse postpartum. The underlying mechanisms and the necessary duration of breastfeeding that provide long-term protection against postpartum smoking relapse are unknown. Aims: We aimed to examine (1) associations of smoking cessation with breastfeeding initiation and duration; (2) necessary breastfeeding duration to reduce or prevent risk of postpartum smoking relapse. Methods: In this cohort study, we recruited 55 mothers, either smoking or have quit smoking, who recently delivered their baby from the Greater Buffalo area, NY, USA. Results: Quitters had a higher breastfeeding initiation rate (73.7% versus 30.8%; p = 0.029) and breastfed longer (p < 0.024) than nonquitters. Mothers who never breastfed relapsed quicker than mothers who did (p = 0.039). There was a 28% reduction in smoking relapse at 12 months postpartum for every month longer of breastfeeding duration (confounder-adjusted hazard ratio, 0.72 [95% confidence interval, 0.55-0.94]; p = 0.014). The estimated smoking relapse risk was 60.0% for nonbreastfeeding, 22.4% for 3 months of breastfeeding, 8.4% for 6 months of breastfeeding, and 1.2% for 12 months of breastfeeding. Conclusion: Smoking cessation was associated with increased breastfeeding initiation and duration. Smoking relapse risk decreased with longer breastfeeding duration, and 12 months of breastfeeding may help to prevent smoking relapse. An integrated intervention of maternal smoking cessation and breastfeeding promotion is promising to enhance both behaviors.

Risk Factors for Enterotoxigenic Bacteroides fragilis Infection and Association with Environmental Enteric Dysfunction and Linear Growth in Children: Results from the MAL-ED Study.

ABSTRACT.Despite reports of enterotoxigenic Bacteroides fragilis (ETBF) isolation from asymptomatic children, no reports exist regarding the possible association of ETBF with long-term complications such as development of environmental enteric dysfunction (EED) and subsequent linear growth faltering in childhood. We aimed to establish a potential association between the burden of asymptomatic ETBF infection and EED and linear growth at 24 months of age using the data collected from 1,715 children enrolled in the multi-country birth cohort study, known as the Etiology, Risk Factors, and Interactions of Enteric Infections and Malnutrition and the Consequences for Child Health study. Using Poisson regression models, we evaluated the site-specific incidence rate and, subsequently, identified the risk factors and assessed the association between the burden of ETBF infection and EED score and linear growth at 24 months of age. The overall incidence rate of ETBF infections per 100 child-months across all study sites was 10.6%, with the highest and lowest incidence of ETBF infections being reported in Tanzania (19.6%) and Peru (3.6%), respectively. Female gender, longer duration of breastfeeding, and improved water access, sanitation, and hygiene practices, such as improved drinking water source, improved sanitation, and improved floor material in households, along with enhanced maternal education and less crowding in the households were found to be protective against incidences of ETBF infection. The burden of ETBF infections was found to have significant associations with EED and linear growth faltering at 24 months of age across all the study sites. Our findings warrant regular clinical monitoring to reduce the burden of ETBF infections and diminish the burden of enteropathy and linear growth faltering in childhood.

Association Between Infant Sleep Location and Breastfeeding.

Objective: Studies have shown that mothers sleeping with their babies have longer breastfeeding duration. Bedsharing (BS) is thought to be a risk factor for Sudden Infant Death Syndrome. The aim was to investigate the frequency of BS and roomsharing (RS) and the effect of those on breastfeeding during the first 2 years of life. Also to evaluate risk-bearing situations regarding sleep environment. Methods and Study Design: This is a cross-sectional study, with retrospective cohort features for the evaluation of some data. The setting was a Well-Child Clinic at Bakırköy Research and Training Hospital. The children were followed from the first month until survey. Feeding history was collected retrospectively from child health records. Parents were surveyed concerning sleeping location and sleeping arrangements with a questionnaire. The study encompassed 351 children and their families. Results: The rate of exclusive breastfeeding was found to be 50.2% for the first 6 months of life and BS increased in exclusively breastfed infants. When breastfeeding continued after 6 months, the trend of increased BS through months was observed. RS, BS, and breastsleeping rates were 80.6%, 22.8%, 56.1%, respectively, in the whole cohort. Working mothers and mothers >35 years of age were significantly more likely to bedshare. Cigarette smoking in BS parents was identified as a child health risk. Unsafe sleep environment was found in 72.4% of the group. Conclusions: BS increases breastfeeding for the first 6 months. Families need guidance on safe sleeping practices and should be advised regarding avoidable risks and unsafe situations in BS. Parents should be counseled to make informed decisions.

Association of early feeding practices with dietary patterns of 7-year-olds from the birth cohort Generation XXI

Early feeding practices have been related to child's body mass index (BMI), however, their role in establishing dietary patterns is less well understood. The aim of this study was to examine the association of parent-reported early feeding practices (breastfeeding duration, type of foods and timing of complementary feeding) and dietary patterns identified at age 7 to explain BMI z-scores at 10 years of age. Participants were children from the Generation XXI cohort, evaluated at 4, 7 and 10 years of age (n = 3673). At 7 years-old, dietary intake was assessed with a validated food-frequency questionnaire. Two dietary patterns were previously derived: “Energy-dense foods” (higher in energy-dense foods, and lower in vegetable soup, significantly associated with BMI z-score at 10 years-old, and the “Fish-based” dietary pattern (higher in fish consumption and low in energy-dense foods). Adjusted sex-stratified associations were estimated by generalized linear models. Boys and girls who were never breastfed or were breastfed for a very short duration had lower scores in the “Fish-based” dietary pattern, compared to those with longer breastfeeding durations (Boys: β = −0.219; 95%CI: 0.361; −0.077; Girls: β = −0.223; 95%CI: 0.358; −0.088). No significant associations between breastfeeding and the “Energy-dense foods” dietary pattern were found. Boys and girls who were offered cereals as a first food during complementary feeding, in comparison with soup, presented lower scores in the “Energy-dense foods” dietary pattern (Boys: β = −0.183; 95%CI: 0.292; −0.074; Girls: β = −0.155; 95%CI: 0.259; −0.050), but only girls presented higher scores in the ‘Fish-based’ dietary pattern (β = 0.137; 95%CI: 0.006; 0.267). The age of introduction of complementary feeding was not significantly associated with the dietary patterns. Parents should be supported in their infant feeding decisions, given the potential effects of breastfeeding duration and first foods at complementary feeding on shaping longer term dietary patterns of young children.

The importance of sleep and parity in understanding changes in weight and breastfeeding behavior among postpartum women

BackgroundBreastfeeding duration has been linked with the health of both women and their children, but research that considers women's weight change postpartum and practical factors that may impact their quality of life (i.e., sleep quantity, number of children) is limited. MethodA survey was administered to 568 women (M age = 31.32 years; SD = 4.21) who had given birth within the past year. The survey included assessments of pre- and post-pregnancy weight and height, breastfeeding practices, current sleep quantity, presence of breastfeeding-specific support, and other demographics including their total number of children. ResultsGreater pre-pregnancy to postpartum weight increase was related to shorter duration of breastfeeding. Mothers who exclusively breastfed for the first six months had less postpartum weight increase (i.e., the discrepancy between their pre-pregnancy and post-pregnancy weight was smaller) than those who did not. Fewer children and greater hours of sleep were significantly associated with longer duration of breastfeeding. Sleep partially accounted for the relationship between body mass index change and breastfeeding duration. Breastfeeding-specific support did not impact the effect of low sleep on shorter breastfeeding duration. ConclusionsDuration of breastfeeding may suffer due to fatigue. Sleep plays a key role in understanding the ways in which weight change impact breastfeeding behavior. Greater holistic support for mothers in the postpartum period is needed to foster an environment that encourages breastfeeding.

Childhood obesity and adverse cardiometabolic risk in large for gestational age infants and potential early preventive strategies: a narrative review.

Accumulating evidence indicates that obesity and cardiometabolic risks become established early in life due to developmental programming and infants born as large for gestational age (LGA) are particularly at risk. This review summarizes the recent literature connecting LGA infants and early childhood obesity and cardiometabolic risk and explores potential preventive interventions in early infancy. With the rising obesity rates in women of childbearing age, the LGA birth rate is about 10%. Recent literature continues to support the higher rates of obesity in LGA infants. However, there is a knowledge gap for their lifetime risk for adverse cardiometabolic outcomes. Potential factors that may modify the risk in early infancy include catch-down early postnatal growth, reduction in body fat growth trajectory, longer breastfeeding duration, and presence of a healthy gut microbiome. The early postnatal period may be a critical window of opportunity for active interventions to mitigate or prevent obesity and potential adverse metabolic consequences in later life. A variety of promising candidate biomarkers for the early identification of metabolic alterations in LGA infants is also discussed. IMPACT: LGA infants are the greatest risk category for future obesity, especially if they experience rapid postnatal growth during infancy. Potential risk modifying secondary prevention strategies in early infancy in LGA infants include catch-down early postnatal growth, reduction in body fat growth trajectory, longer breastfeeding duration, and presence of a healthy gut microbiome. LGA infants may be potential low-hanging fruit targets for early preventive interventions in the fight against childhood obesity.

Association between breastfeeding and breast, thyroid, and cervical cancer among Korean adult women based on the Korean Genome and Epidemiology Study: a cohort study.

PurposeThe purpose of this study was to explore the association between breastfeeding and the prevalence of breast, thyroid, and cervical cancer among Korean adult women.MethodsThe study was a secondary analysis of data from the Korea Genome and Epidemiology Study. The final samples were 113,944 Korean women among 173,205 urban-based cohort participants collected between 2004 and 2013 for adults aged forty and over. To determine the association between female cancers and breastfeeding experience, the number of childbirth, and total breastfeeding duration, logistic regression analysis was done. The demographic characteristics, health behavior, and female history were adjusted.ResultsThe prevalence of breast cancer was 1.37 times higher in the non-breastfeeding group than in the breastfeeding group. Compared to having breastfed for more than 36 months, the prevalence of thyroid cancer was 1.68 times higher at breastfeeding for 13 to 36 months, 1.67 times higher at breastfeeding for 6 to 12 months, and 2.06 times higher at breastfeeding less than 6 months. Also, the prevalence of cervical cancer was 1.54 times higher at breastfeeding for 13 to 36 months, compared to breastfeeding for more than 36 months.ConclusionThis study found that breastfeeding experience and a longer breastfeeding duration are associated with reduced risk of breast, thyroid, and cervical cancer in Korean women. It can be used as a basis for encouraging breastfeeding, and suggests further research on modifiable factors that reduce cancer risks.

Longer breastfeeding duration, better child development? Evidence from a large-scale survey in China

Based on a large-scale survey in China, we use the generalized propensity score matching method and instrumental variable method to explore the effect of breastfeeding duration on child development, and find that there is a relatively stable “U” relationship between breastfeeding duration and children’s early behavioral performance, with the optimal breastfeeding duration (6–10 months) promoting children’s early behavioral performance. However, more than the optimal breastfeeding duration will delay child development. We further find that the effect of breastfeeding duration on child development varies among different groups. There is evidence that the optimal breastfeeding duration has a greater positive effect on children from disadvantaged backgrounds. The conclusions of this paper have obvious practical value for the policy of child development strategies and parenting practices. Given the importance of early child development, there should be a reasonable breastfeeding duration, and the feeding interventions for disadvantaged children can bring higher returns.

The Effect of Maternal Self-Regulated Motivation on Breastfeeding Continuation.

Women frequently report breastfeeding problems in the early postpartum period. Women who have self-endorsed beliefs that breastfeeding benefits their babies and themselves are more likely to continue breastfeeding despite breastfeeding barriers. Maternal self-endorsed beliefs is a key component of maternal self-regulated motivation. The present study examined the association between maternal self-regulated motivation, breastfeeding duration and exclusivity in Chinese women. This was a prospective cohort study, of which we recruited participants in postnatal maternity units of publicly funded hospitals in Hong Kong. Postpartum women were asked to fill in the validated breastfeeding self-regulation questionnaire (BSRQ) before hospital discharge and their breastfeeding status was assessed by telephone follow-ups at 6 and 12weeks postpartum. Multiple logistic regression was used to study the relationship between breastfeeding self-regulated motivation and the duration of breastfeeding at follow-up. At 6 and 12weeks postpartum, women who breastfed exclusively scored significantly higher in self-regulated motivation than those who formula-fed. The self-regulated motivation was associated with higher odds of exclusive breastfeeding at 6weeks and any breastfeeding at 12weeks postpartum. The study found that self-regulated motivation was positively related to breastfeeding duration. Maternal self-regulated motivation toward breastfeeding could be enhanced by the availability of social support and breastfeeding-friendly facilities, resulting in longer breastfeeding duration.

COVID-19 mRNA vaccine and antibody response in lactating women: a prospective cohort study

BackgroundImmunological protection via breastfeeding is well known. The immunological profile of human milk changes during lactation. No clinical trials have been conducted in lactating women with the newest mRNA vaccines against SARS- CoV-2. A Few studies have shown the presence of antibodies in breastmilk after vaccination. The aim of this work is to study possible antibodies transfer via breastmilk and also the immunological characteristics of lactating women compared to non-lactating women, after using the BNT162b2 Pfizer vaccine.MethodsThis is a prospective cohort study with a convenience homogenous sample of 24 healthcare workers (14 lactating and 10 non-lactating women) enrolled at the time of COVID-19 vaccination. Clinical data was registered in a questionnaire. Titers of SARS-CoV-2 spike IgG, IgA and IgM were quantified in post vaccination blood and human milk. Antibody quantification was performed by an in-house ELISA to SARS-CoV-2 trimeric spike protein.ResultsAll women showed immunity after vaccination with positive antibodies for IgM, IgA and IgG antibodies. The dominant serum antibody response was IgG. Modest levels of antibodies in breastmilk of lactating mothers were observed in this study, especially IgG in 42.9%. There was a moderate association between higher titers of IgG and a longer duration of breastfeeding (R= 0.55, p=0.041).ConclusionsEvidence of antibody transfer in human milk after COVID-19 vaccination is scarce. The presence of antibodies in human milk is reported, but immunization through breastfeeding is still to be established.

Early life and socio-economic determinants of dietary trajectories in infancy and early childhood \u2013 results from the HSHK birth cohort study

BackgroundEarly childhood is a period when dietary behaviours are established. This study aimed to examine the longitudinal intake of core and discretionary foods and identify early life and socio-economic factors influencing those intakes.MethodsMother-infant dyads (n = 934) from the Healthy Smiles Healthy Kids study, an ongoing birth cohort study, were interviewed. The information on ‘weekly frequency of core and discretionary foods intake’ using a food frequency questionnaire was collected at 4 months, 8 months, 1 year, 2 years and 3 years age points. Group-based trajectory modelling analyses were performed to identify diet trajectories for ‘core’ and ‘discretionary’ foods respectively. A multinomial logistic regression was performed to identify the maternal and child-related predictors of resulting trajectories.ResultsThe intake of core and discretionary foods each showed distinct quadratic (n = 3) trajectories with age. Overall, core foods intake increased rapidly in the first year of life, followed by a decline after age two, whereas discretionary foods intake increased steadily across the five age points. Multiparity (Relative Risk (RR): 0.46, 95%CI: 0.27–0.77), non-English speaking ethnicity of mother (RR: 0.66, 95%CI: 0.47–0.91) and having a single mother (RR: 0.40, 95%CI: 0.18–0.85) were associated with low trajectories of core foods intake whereas older maternal age (RR: 1.05, 95%CI: 1.01–1.08) and longer breastfeeding duration (RR: 1.02, 95%CI: 1.00–1.03) were associated with higher trajectories of core foods intake. Also, multiparity (RR 2.63, 95%CI: 1.47–4.70), low maternal education (RR 3.01, 95%CI: 1.61–5.65), and socio-economic disadvantage (RR 2.69, 95%CI: 1.31–5.55) were associated with high trajectories of discretionary foods intake. Conversely, longer duration of breastfeeding (RR 0.99, 95%CI: 0.97–0.99), and timely introduction of complementary foods (RR 0.30, 95%CI: 0.15–0.61) had a protective effect against high discretionary foods consumption in infancy and early childhood.ConclusionChildren’s frequency of discretionary foods intake increases markedly as they transition from infancy to preschool age, and the trajectories of intake established during early childhood are strongly influenced by socio-demographic factors and infant feeding choices. Hence, there is a need for targeted strategies to improve nutrition in early childhood and ultimately prevent the incidence of chronic diseases in children.

Children are victims of industrialization and commercialization of early feeding practices: A review of obesity in preschool children in Egypt

Introduction: Obesity Is Global Problem Which Begins From Early Childhood. Early Exclusive Breastfeeding (EBF) without foods or Milk Formula (MF) before 6 months, with continued breastfeeding for two years are optimal feeding practices. Aim: To review studies conducted to assess the nutritional status of preschool children with a focus on obesity and stunting and their association with EBF vs MF feeding. Methods: We used online search engines of the Egyptian university libraries consortium (www.eulc.edu) to search for studies on overweight, obesity stunting and wasting in preschool children. We identified 919 theses that were filtered to 32 studies then to 18 theses fitting the criteria of the study. Analysis of the pooled data was done for the studies with children who were EBF (2 studies) vs children who were exposed to MF (16 studies) by age and sex. Findings: Pooled analysis for children aged 6-59 months among MF vs. EBF studies as follows: overweight 5.4% vs. 3.45%, obesity 13.8% vs. 5.65%, stunting 21.6% vs. 1.15% and wasting 9.7% vs. 0.85% respectively. Obesity and overweight were higher in males in both studies, whereas stunting and wasting were higher in females in both studies (ages 0-72 months). Early and extended MF feeding, foods before 6 months of life, chips and canned drinks were prominent risk factors for obesity. Large family size was associated with obesity and short birth interval with stunting. Colostrum feeding, longer duration of breastfeeding, fruits and vegetables were protective. Obese children showed clinical signs of anemia, vitamin A and D deficiency, severe asthma and developmental delay. Conclusions: Obesity and MF feeding beyond 6 months and well into 5 years of age threaten child health. Policies and legislations are needed to control, counter and monitor marketing tactics supported by guiding messages. Keywords: Obesity; overweight; stunting; wasting; fast foods; breastfeeding; birth spacing; child development; infancy; preschool children; anthropometry; growth.

Breastfeeding and Responsive Parenting as Predictors of Infant Weight Change in the First Year.

To test breastfeeding duration and responsive parenting as independent predictors of infant weight change from birth to 12 months, and to test the moderating effect of a tiered parenting intervention on relations between breastfeeding and responsive parenting in relation to infant weight change. Mother-infant dyads (N = 403) were participants in the ongoing Smart Beginnings (SB) randomized controlled trial testing the impact of the tiered SB parenting model that incorporates two evidence-based interventions: Video Interaction Project (VIP) and Family Check-Up (FCU). The sample was low income and predominantly Black and Latinx. Responsive parenting variables (maternal sensitivity and intrusiveness) came from coded observations of mother-infant interactions when infants were 6 months. Continuous weight-for-age (WFA) z-score change and infant rapid weight gain (RWG) from 0 to 12 months were both assessed. Longer breastfeeding duration was significantly associated with less WFA z-score change. The relationship between breastfeeding duration and WFA z-score change was significant only for infants in the intervention group. Intrusive parenting behaviors were also associated with greater WFA z-score change after accounting for breastfeeding duration. This study is one of the first to test both breastfeeding and parenting in relation to infant weight gain in the first year. Findings may have implications for family-focused child obesity prevention programs.

Examining patterns of postnatal feeding in relation to infant's weight during the first year

BackgroundThere is mixed evidence regarding specific infant feeding behaviors and later risk for overweight and obesity. We sought to detect underlying patterns in duration of breastfeeding, introduction of solid foods and sweetened beverages, in order to understand the relation to later weight. MethodsPatterns of postnatal feeding were examined among infants enrolled in the Infant Feeding Practices Study II (N = 3033). At monthly intervals, mothers reported on the duration of any and exclusive breastfeeding, age of solid food and sweetened beverage introduction, and reported infant weight at ages 9- and 12-months. Latent profile analysis was used to empirically derive patterns of postnatal feeding and examine associations with weight z-scores at 9 and 12 months. ResultsTwo profiles emerged: (1) Short breastfeeding duration and early introduction to solid foods and sweetened beverages (Short BF/Early Introduction; 53%) and (2) longer breastfeeding duration and later introduction to solid foods and sweetened beverages (Longer BF/Later Introduction; 43%). Infants in the Shorter BF/Early Introduction profile had significantly greater weight z-scores at 9 (M = 0.18) and 12 months (M = 0.26), compared to those in the Longer BF/Later Introduction profile (M = −0.21; M = −0.17, respectively). ConclusionsOverall, shorter BF duration and earlier food and sweetened beverage introduction is associated with higher weight z-scores at 9 and 12 months. Early intervention should aim to promote breastfeeding and later introduction of solids and discourage consumption of sweetened beverages. These postnatal patterns of feeding behaviors provides important context to inform targeted interventions aimed at reducing risk for later obesity.
