Cross-Sectional Analysis of Infant Diet, Outcomes, Consumer Behavior and Parental Perspectives to Optimize Infant Feeding in Response to the 2022 U.S. Infant Formula Shortage. Nutrients 2024; 16:748. [PMID: 38474876 DOI: 10.3390/nu16050748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 02/23/2024] [Accepted: 02/27/2024] [Indexed: 03/14/2024] Open
Abstract
In May of 2022, millions of U.S. parents encountered uncertainty in safely feeding their infants due to the infant formula shortage. METHODS An anonymous, electronic, cross-sectional, retrospective survey was used. RESULTS U.S. parents (n = 178) whose infants were ~10 weeks old during the shortage completed the survey. Of parents, 81% switched formulas during the shortage, 87% switched because they could not find the formula they typically used, 34% switched 3-5 times, 29% of parents visited ≥4 stores/24 h and 26% of parents traveled >20 miles/24 h to purchase formula. Use of infant formula increased (p < 0.01); in infants requiring specialty formula, use of intact cow's milk formula increased (p < 0.05) and use of premature infant formulas decreased (p < 0.05). Infants relying on specialty formulas experienced at least one undesirable outcome compared with non-specialty users. Parents used social media, relatives/friends and healthcare providers for support during the shortage, but their helpfulness scores were suboptimal. Parents reported the need for greater infant formula availability, free prenatal lactation education and postpartum lactation support. CONCLUSIONS Government, regulatory and healthcare policy oversight are needed to protect the infant feeding system, including more commercially available products, access to banked donor milk and lactation support.

Abstract
BACKGROUND In May of 2022, parents living in the United States experienced a dramatic infant formula shortage caused by supply chain issues and the recall of several infant formula products over contamination concerns. METHODS An anonymous, electronic, cross-sectional survey was designed to understand infant feeding practices, parental experience and perceived support during the crisis. RESULTS Ninety-nine parents that lived in the U.S. and fulfilled study criteria completed the survey. 66% of respondents were female, and 75% of respondents were recipients of the Special Supplemental Nutrition Program for Women Infant Children (WIC). Parental mean age was 30.0 years, and the mean infant age was 26.8 weeks. The number of individuals that used at least one unsafe infant feeding practice increased from 8% before the infant formula shortage to 48.5% during the shortage (p < 0.001). 79% of parents fed their infants U.S. infant formula brands and 39% of parents fed their infants imported infant formula brands before the shortage which were significantly reduced during the shortage to 27% (p < 0.005) and 11% (p < 0.005), respectively. The percentage of parents that reported infant feeding practices before and during the infant formula shortage significantly increased from 2 to 28% for banked donor milk use (p < 0.005); 5-26% for use of human milk from informal sharing (p < 0.005); and 2-29% for use of watered-down infant formula (p < 0.005). The resources that parents reported as most helpful in navigating the crisis differed by parental sex and WIC recipient status and included other parents, friends, and family; lactation consultants; healthcare providers; and WIC. CONCLUSIONS Our study found that feeding practices in response to the infant formula shortage may pose health risks to infants including nutrition and food insecurity. These data suggest the need for policy changes within regulatory and the healthcare system to provide families with clinical prenatal and postnatal lactation support, access to pasteurized banked donor milk, and access to more commercially available products.

MATERNAL & CHILD NUTRITION 2022; 18:e13389. [PMID: 35757994 PMCID: PMC9480963 DOI: 10.1111/mcn.13389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2021] [Revised: 03/04/2022] [Accepted: 03/14/2022] [Indexed: 11/28/2022]
Abstract
Human milk sharing (HMS) is growing in popularity as an infant-feeding strategy in the United States. HMS families are a hidden population because HMS is a nonnormative and stigmatized behaviour. Thus, gaining access to HMS participants is challenging, and research on this topic remains limited. In particular, little is known about the broader infant-feeding behaviours of HMS parents. This study aimed to describe and compare the infant-feeding behaviours and HMS practices among a network of HMS donors and recipients. A detailed online survey was distributed to HMS parents in the Washington, DC region. Bivariate analyses were used to summarize the data by donor/recipient status when possible. Group differences were tested using analysis of variance for continuous variables and χ2 tests for categorical variables. Donors and recipients did not differ in their sociodemographic characteristics. Recipients were significantly more likely than donors to have experienced complications of labour and delivery, traumatic birth, postpartum depression or a negative breastfeeding experience. Donors and recipients did not differ significantly in their duration of lactation or HM-feeding. Interestingly, 30% of recipients ever produced excess milk and 21% of donors ever had difficulty producing enough milk for their child. Compared with donors, recipients faced numerous maternal health challenges, but were still able to achieve a long duration of HM-feeding. HMS recipients represent a vulnerable group who may benefit from additional psychosocial and lactation support to improve their health and breastfeeding outcomes. Additional research is needed to investigate the associations between HMS participation, infant-feeding behaviours and lactation outcomes.

Abstract
Mastitis is a debilitating condition that can impact around 20% of mothers and is characterized by fever, flu-like symptoms and tender, swollen areas of the breasts. Despite the emerging evidence that breast milk dysbiosis is an underlying cause of mastitis, breast pumps have been implicated as a predisposing risk factor in the pathophysiology of mastitis in breastfeeding mothers. Previous studies have suggested that the use of a breast pump increases a mother's risk for developing mastitis, however, incidence rates of mastitis over the stages of lactation do not match breast pump usage rates. Furthermore, breast pumps, even when used at low vacuum, still promote some breast drainage, thus avoiding milk stasis, which is considered a key factor in the development of mastitis. As a consequence, these data suggest that the literature association of breast pumps with mastitis is more a case of reverse causation and not direct association. Moreover, it is important to note that breast pumps are actually a part of the conservative management of mastitis. In combination, these data show that the breast pump should not be considered a driver in the pathophysiology of mastitis in women.

Abstract
BACKGROUND There 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. METHODS Patterns 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. RESULTS Two 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). CONCLUSIONS Overall, 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.

Abstract
The belief that breastfeeding promotes maternal bonding is widely held by both the public and professional health organizations. Yet to our knowledge, all research examining the link between breastfeeding and maternal behavior in humans has been correlational, limiting our ability to draw causal conclusions. In many mammals, the hormone prolactin, which is central to milk production, rises in response to each breastfeeding session and promotes maternal sensitivity, yet there is a dearth of research in human mothers. To fill these research gaps, we randomly assigned 28 breastfeeding mothers to either breastfeed in the lab or feed their infants previously expressed breastmilk in a bottle before participating in a video-recorded free play session with their infant. Plasma prolactin was measured 40 min after the start of the feeding session and video observations were coded for maternal sensitivity. We found that women randomly assigned to breastfeed were more sensitive to infant cues than women randomly assigned to bottle-feed. Prolactin levels did not differ between feeding groups, although prolactin was positively correlated with maternal sensitivity. Our results suggest that feeding milk directly from the breast (compared to bottle-feeding) increases maternal sensitivity towards infants, at least in the short term.

Abstract
BACKGROUND Infant nutrition can influence development, eating behaviors and obesity risk. Nearly half of infants in the U.S. are in non-parental care where they consume much of their daily nutrition. Because little is known about the quality of infant nutrition in childcare, the study objective was to characterize the foods and beverages provided to infants in childcare in California. METHODS From a randomly selected sample of 2,400 licensed childcare in California, 736 responded to a 2016 survey; a subset of 297 cared for infants. Differences in 26 foods and 7 beverages provided between centers and homes, and by CACFP participation, were assessed using logistic regression models adjusted for CACFP participation and whether the site was a center or home, respectively. RESULTS Several differences between centers and homes were identified. One the day prior to the survey, more centers than homes ever provided cow's milk (25.1% vs 13.0%, p = 0.02) and whole grains (76.7% vs 62.9%, p = 0.03), and fewer centers than homes provided frozen treats (1.4% vs 10.3%, p = 0.003). When comparing difference by CACFP participation, fewer CACFP than non-CACFP sites usually provided breastmilk (32.6% vs 54.2%, p = 0.0004) and ever provided cow's milk (14.2% vs 37.1%, p < 0.0001). On the day prior to the survey, more CACFP than non-CACFP provided vegetables (91.0% vs 80.8%, p = 0.02), fruit (centers only) (97.2% vs 80.8%, p = 0.0003), and infant cereals (86.0% vs 61.2%, p < 0.0001). Fewer CACFP than non-CACFP provided sweetened yogurt (14.8% vs 36.7%, p < 0.0001). CONCLUSIONS FOR PRACTICE Childcare centers and CACFP participants tended to serve nutritious foods more than childcare homes and non-CACFP participants, respectively. Additional education and policies for childcare providers on appropriate foods and beverages for infants is recommended.

Effects of Fluoride Exposure on Primary Human Melanocytes from Dark and Light Skin. TOXICS 2020; 8:toxics8040114.

Abstract
Fluoride exposure has adverse effects on human health that have been studied in vitro in cell culture systems. Melanocytes are the melanin pigment-producing cells that have a significant role in the regulation of the process of melanogenesis, which provides several health benefits. Melanocytes are present in the oral cavity, skin, brain, lungs, hair, and eyes. However, to date, there has been no study on the effects of fluoride exposure on melanocytes. Hence, in the current study, we have studied the effects of sodium fluoride (NaF) exposure on neonatal human epidermal melanocytes (HEMn) derived from two different skin phototypes, lightly pigmented (LP) and darkly pigmented (DP). We have assessed the impact of a 24 h and 72 h NaF exposure on metabolic activity and membrane integrity of these cells. In addition, we have evaluated whether NaF exposure might have any impact on the physiological functions of melanocytes associated with the production of melanin, which is regulated by activity of the enzyme tyrosinase. We have also assessed if NaF exposure might induce any oxidative stress in LP and DP melanocytes, by evaluation of production of reactive oxygen species (ROS) and measurement of mitochondrial membrane potential (MMP) levels. Our results showed that HEMn-LP cells showed a higher sensitivity to NaF cytotoxicity than HEMn-DP cells, with significant cytotoxicity at concentrations >1 mM, while concentration range 0.25–1 mM were nontoxic and did not lead to oxidative stress, and also did not alter the levels of intracellular melanin or cellular tyrosinase activity, indicating that treatment up to 1 mM NaF is generally safe to melanocytes from both pigmentation phototypes.

Abstract
Dental caries remains the most common chronic disease of childhood in the United States. Caries is a largely preventable condition, and fluoride has proven effectiveness in caries prevention. This clinical report aims to clarify the use of available fluoride modalities for caries prevention in the primary care setting and to assist pediatricians in using fluoride to achieve maximum protection against dental caries, while minimizing the likelihood of enamel fluorosis. Fluoride varnish application is now considered the standard of care in pediatric primary care. This report highlights administration, billing, and payment information regarding the fluoride varnish procedure.

Abstract
Breast surgery increases the risk for difficulties with milk production and breastfeeding. Research on lactation outcomes of breast augmentation with implants is reassuring, but reveals a significant risk of low milk production that varies with the type of surgery and position of the implants. Understanding the potential effects of breast implants on breastfeeding can help lactation professionals optimize outcomes for families with a history of augmentation mammaplasty.

Abstract
Objective: An efficient method for measuring maternal milk production is needed. Our objectives were to: (1) validate a milk production rate (MPR) protocol in exclusively breastfeeding mothers; (2) determine MPR change following 48 hours of increased breast emptying; (3) assess agreement between MPR and infant test-weighing; and (4) characterize MPR in early postpartum exclusively breastfeeding mothers. Materials and Methods:N = 23 mothers emptied both breasts hourly over 3 hours (h0, h1, h2, and h3). We estimated steady-state MPR as mean (h2 and h3). Subset A mothers (n = 5) also completed MPR measurements after 48 hours of increased breast emptying. Subset B mothers (n = 16) also test-weighed for 48 hours. We used paired t-test to examine within-participant change in hourly milk yield and MPR; and we used Bland-Altman analysis to compare 24-hour milk production (g/24 hours) measured using test-weight versus MPR. Results are reported as mean ± standard deviation or (±95% limits of agreement). Results: Mothers were 54 ± 14 days postpartum. Paired difference in h3-h2 hourly milk yield was not significantly different (p > 0.05, 3 ± 10 g/hour). In Subset A (n = 5), MPR declined from 50 ± 13 to 43 ± 16 g/hour (p = 0.003) following 48 hours of increased breast emptying. In Study B (n = 16), mean infant test-weighed intake (TW) was 717 ± 119 g/24 hours, and mean MPR was 1,085 ± 300 g/24 hours. Mean difference (MPR-test-weigh) and mean ratio (MPR/test-weigh) significantly increased as MPR increased (p < 0.05). For infants with adequate weight gain (>20 g/24 hours, n = 12), mean MPR = 48 ± 12 g/hour (range, 35-78 g/hour). Conclusion: MPR is a valid measure of current maternal milk production capacity, but is not accurate for evaluating infant intake in exclusively breastfeeding dyads.

Abstract
OBJECTIVE To examine the relationships among food insecurity, breastfeeding, and other related feeding practices by race/ethnicity among US infants and toddlers. DESIGN National Health and Nutrition Examination Surveys 2009-2014, a nationally representative cross-sectional survey. PARTICIPANTS Infants and toddlers aged 0-24 months with complete data on household food security status (n = 2,069). MAIN OUTCOME MEASURES Initiation of breastfeeding (yes or no), duration of breastfeeding, and age of introduction to foods/drinks. ANALYSIS Differences in feeding practices by food security status were tested in survey-weighted, stratified multiple regression models. RESULTS Breastfeeding initiation rates among non-Hispanic whites, Hispanics, and non-Hispanic blacks were estimated at 80.0%, 77.5%, and 57.4%, respectively (P < .001). A total of 43% of infants and toddlers were introduced to foods/drinks before 4 months. After adjusting for household income, education, and other covariates, food insecurity was not a significant predictor of poor feeding behaviors. CONCLUSIONS AND IMPLICATIONS Racial/ethnic disparities existed, with non-Hispanic black infants at the highest risk for never being breastfed, nor to continue through the recommended period of breastfeeding. Food insecurity was not shown to affect breastfeeding and other infant feeding practices directly. Further investigation is needed to understand whether food insecurity, through stress and other sociostructural pathways, mediates poor infant feeding practices.

Abstract
The first 2 y of life are characterized by several transitions that can affect growth, development, and eating patterns long term. These include a shift from a primarily milk-based eating pattern to introduction of complementary foods at ∼4-6 mo of age, and passage to family-meal patterns in toddler years. Recognizing the importance of this critical period, the Dietary Guidelines for Americans from 2020 onwards will include guidance for children aged birth to 24 mo (B-24). Few large-scale surveys provide comprehensive, nationally representative, quantitative, recent data on infant and toddler nutrition in the United States. The continuous NHANES has collected data relevant to this initiative since 1999 using standardized interview and examination protocols. These include data on infant feeding practices, dietary intakes (foods, beverages, and supplements), anthropometry, and blood-based nutritional status on nationally representative samples of infants and toddlers. NHANES data can be used to describe large group-level consumption patterns, as well as trends over time for B-24 children overall, and by demographic groups (e.g., race-ethnic and income groups). In addition, NHANES data can be analyzed to examine adherence to nutrition-related recommendations, such as those from the American Academy of Pediatrics (AAP), and to track Healthy People 2020 objectives. This paper provides an update on NHANES nutrition monitoring in B-24 children since our previous publication (which provided details through NHANES 2009-2010) and describes data collection since 2010 and plans for upcoming cycles. It also describes key NHANES-based findings published in the last 5 y on infant feeding practices, dietary intakes and supplement use, and nutritional status of US children aged <2 y. Findings related to existing recommendations, such as from the AAP, are presented when available. This information can inform researchers and policymakers on the state of nutrition in the US B-24 population and its subgroups of interest.

Human milk as "chrononutrition": implications for child health and development. Pediatr Res 2019; 85:936-942. [PMID: 30858473 DOI: 10.1038/s41390-019-0368-x] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2018] [Revised: 02/25/2019] [Accepted: 03/01/2019] [Indexed: 12/12/2022]
Abstract
Human biology follows recurring daily rhythms that are governed by circadian cues in the environment. Here we show that human milk is a powerful form of "chrononutrition," formulated to communicate time-of-day information to infants. However, 85% of breastfed infants in the US consume some milk that does not come directly from the breast but is pumped and stored in advance of feeding. Expressed milk is not necessarily circadian-matched (e.g., an infant might drink breastmilk pumped in the evening on the following morning). Ingesting mistimed milk may disrupt infants' developing circadian rhythms, potentially contributing to sleep problems and decreased physiological attunement with their mothers and environments. Dysregulated circadian biology may compromise infant health and development. Despite wide-ranging public health implications, the timing of milk delivery has received little empirical study, and no major pediatric or public health organization has issued recommendations regarding the circadian-matching of milk. However, potential adverse developmental and health consequences could be ameliorated by simple, low-cost interventions to label and circadian-match stored milk. The current paper reviews evidence for human milk as chrononutrition and makes recommendations for future research, practice, and policy.

Abstract
OBJECTIVE The goal of the present study was to estimate prevalence and maternal risk factors for infant beverage consumption. DESIGN Observational birth cohort. SETTING Central North Carolina, USA. PARTICIPANTS Mothers 20-36 weeks pregnant were surveyed every 3 months through their infant's first year (n 666) on their sociodemographics and infant's consumption frequency of 100 % fruit and vegetable juices and sugar-sweetened-beverages (SSB). Repeated-measure models, using a compound symmetry covariance structure, were used to assess the association of sociodemographic and maternal predictors with introducing juice and SSB separately and explored interaction terms with time to determine how the effects of the predictors change over time. RESULTS On average, mothers were 28 years old, 72 % were non-Hispanic Black and 59 % were low-income. We found time by race, income, education, maternal age and breast-feeding duration interactions for both juice and SSB consumption. At approximately 6-7 months of age through 12 months of age, being Black, having a lower income (≤$US 20 000 v. >$US 20 000 per year) and education (less than high-school degree v. high-school degree or higher), being younger (<26 years v. ≥26 years) and breast-feeding for fewer than 26 weeks were each associated with introduction of both juice and SSB consumption. CONCLUSIONS Future efforts are needed to raise awareness on the importance of national recommendations of limiting juice and SSB for infants, together with decreasing disparities in unhealthy beverage intake early in life.

Abstract
INTRODUCTION Breast feeding is associated with many health benefits for mothers and infants. But despite extensive public health efforts to promote breast feeding, many mothers do not achieve their own breastfeeding goals; and, inequities in breastfeeding rates persist between high and low-income mother-infant dyads. Developing targeted programme to support breastfeeding dyads and reduce inequities between mothers of different socioeconomic status are a priority for public health practitioners and health policy decision-makers; however, many jurisdictions lack the timely and comprehensive population-level data on infant-feeding practices required to monitor trends in breastfeeding initiation and duration. This protocol describes the establishment of a population-based infant-feeding database in the Canadian province of Manitoba, providing opportunities to develop and evaluate breastfeeding support programme. METHODS AND ANALYSIS Routinely collected administrative health data on mothers' infant-feeding practices will be captured during regular vaccination visits using the Teleform fax tool, which converts handwritten information to an electronic format. The infant-feeding data will be linked to the Manitoba Population Research Data Repository, a comprehensive collection of population-based information spanning health, education and social services domains. The linkage will allow us to answer research questions about infant-feeding practices and to evaluate how effective current initiatives promoting breast feeding are. ETHICS AND DISSEMINATION Approvals have been granted by the Health Research Ethics Board at the University of Manitoba. Our integrative knowledge translation approach will involve disseminating findings through government and community briefings, presenting at academic conferences and publishing in scientific journals.

Soto-Ramírez N, Kar S, Zhang H, Karmaus W. Infant feeding patterns and eczema in children in the first 6 years of life. Clin Exp Allergy 2017; 47:1285-1298. [PMID: 28815821 DOI: 10.1111/cea.12998] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2017] [Revised: 07/10/2017] [Accepted: 08/05/2017] [Indexed: 11/28/2022]
Abstract
BACKGROUND Modes of infant feeding such as direct and indirect breastfeeding, and formula feeding, and their combinations may play a role in child health. OBJECTIVE The aim was to investigate which feeding patterns in the first 6 months pose risks of eczema/skin allergy in children up to 6 years compared to direct breastfeeding for at least 3 months. METHODS The Infant Feeding Practices Study II in the United States and its 6-year follow-up provided data on feeding modes in infancy and doctor's diagnosed eczema/skin allergy in the first 6 years of life (1387 infants), based on parental reports. Different feeding patterns were identified. Log-linear models were used to estimate prevalence ratios (PRs) of feeding patterns for doctor's diagnosed eczema/skin allergy in the first 6 years of life, adjusting for confounders. RESULTS Compared to "direct breastfeeding for at least 3 months" (DBF3m), the combination of "direct feeding at the breast (DBF), pumping and feeding breast milk (BM), and formula (FF) in the first months" (DBF/BM/FF) showed a statistically significant higher risk of eczema/skin allergy in the first 6 years of life (PR = 1.46), adjusting for confounders. DBF combined with BM for the first 3 months followed by mixed feeding also had an increased risk (PR = 1.26), although not statistically significant. Formula feeding introduced since birth had no effect on eczema. Among the confounders, paternal eczema and race/ethnicity (Hispanic vs White) were associated with a higher risk of eczema/skin allergy. CONCLUSIONS & CLINICAL RELEVANCE Mixed infant feeding may carry a higher risk of eczema/skin allergy compared to direct feeding at the breast. The recent epidemic of pumping and feeding in the United States and the use of mixed infant feeding modes requires additional studies to provide appropriate and renewed assessments of the risks of feeding modes for the future development of allergies.

Early Feeding Practices and Weight Status at One Year of Age: A Comparison of Hispanic Immigrant Mother-Infant Dyads with Participants of the Infant Feeding Practices Study II. Child Obes 2016; 12:384-91.

Abstract
BACKGROUND Hispanic preschoolers have higher rates of BMI ≥85th percentile than any other racial/ethnic group. To identify underpinnings of this disparity, we compared early feeding practices and subsequent weight status for a sample of infants of low-income, Hispanic immigrant mothers with participants from the Infant Feeding Practices Study II (IFPS II). METHODS Proyecto de Bebés Hispanos Saludables (PBHS) collected medical record data for mother-infant dyads (n = 550) from a large pediatric clinic for low-income families and merged it with IFPS II data (n = 1502) to compare early feeding practices and late infancy weight status. RESULTS Mode of milk delivery for PBHS mothers was less likely to be exclusive breastfeeding at 6 months (9.0% vs. 27.5%), but more likely to be both breast and bottle feeding (43.5% vs. 26.3%) compared to IFPS II mothers. No difference was found in age for solid food introduction. Weight for age of PBHS infants was more likely to be ≥85th percentile at 12 months than IFPS II infants (39.1% vs. 25.4%). Both PBHS and IFPS II infants were more likely to be ≥85th percentile at 1 year if mode of milk delivery was bottle only at 6 months compared to those who were breastfed only, even after adjusting for potential confounders. CONCLUSION Differences in PBHS and IFPS II feeding practices and weight status suggest additional studies of modifiable, early life risk factors are needed to inform clinical and public health interventions that reduce childhood obesity for this growing sector of the US population.

Abstract
BACKGROUND Breastfeeding is important, however not all infants can feed at the breast and methods of expressing milk need evaluation. OBJECTIVES To assess acceptability, effectiveness, safety, effect on milk composition, contamination and costs of methods of milk expression. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (21 March 2016), handsearched relevant journals and conference proceedings, and contacted experts in the field to seek additional published or unpublished studies. We also examined reference lists of all relevant retrieved papers. SELECTION CRITERIA Randomised and quasi-randomised trials comparing methods at any time after birth. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS This updated review includes 41 trials involving 2293 participants, with 22 trials involving 1339 participants contributing data for analysis. Twenty-six of the trials referred to mothers of infants in neonatal units (n = 1547) and 14 to mothers of healthy infants at home (n = 730), with one trial containing mothers of both neonatal and healthy older infants (n = 16). Eleven trials compared one or more types of pump versus hand expression and 14 studies compared one type of pump versus another type of pump, with three of these studies comparing both hand expression and pump types. Twenty studies compared a specific protocol or adjunct behaviour including sequential versus simultaneous pumping protocols, pumping frequency, provision of an education and support intervention, relaxation, breast massage, combining hand expression with pumping and a breast cleansing protocol.Due to heterogeneity in participants, interventions, and outcomes measured or reported, we were unable to pool findings for most of the specified outcomes. It was not possible therefore to produce a 'Summary of findings' table in this update. Most of the included results were derived from single studies. Trials took place in 14 countries under a variety of circumstances and were published from 1982 to 2015. Sixteen of the 30 trials that evaluated pumps or products had support from the manufacturers. The risk of bias of the included studies was variable. Primary outcomesOnly one of the 17 studies examining maternal satisfaction/acceptability with the method or adjunct behaviour provided data suitable for analysis. In this study, self-efficacy was assessed by asking mothers if they agreed or disagreed with the following statement: 'I don't want anyone to see me (hand expressing/pumping)'. The study found that mothers who were using the electric pump were more likely to agree with the statement compared to mothers hand expressing, (mean difference (MD) 0.70, 95% confidence interval (CI) 0.15 to 1.25; P = 0.01, participants = 68). Mothers who were hand expressing reported that the instructions for expression were clearer compared to the electric pump, (MD -0.40, 95% CI -0.75 to -0.05; P = 0.02, participants = 68). Descriptive reporting of satisfaction in the other studies varied in the measures used, did not indicate a clear preference for one pump type, although there was satisfaction with some relaxation and support interventions.We found no clinically significant differences between methods related to contamination of the milk that compared any type of pump to hand expression (risk ratio (RR) 1.13, 95% CI 0.79 to 1.61; P = 0.51, participants = 28), manual pump compared to hand expression, (MD 0.20, 95% CI -0.18 to 0.58; P = 0.30, participants = 142) a large electric pump compared to hand expression (MD 0.10, 95% CI -0.29 to 0.49; P = 0.61, participants = 123), or a large electric pump compared to a manual pump (MD -0.10, 95% CI -0.46 to 0.26; P = 0.59, participants = 141).The level of maternal breast or nipple pain or damage was similar in comparisons of a large electric pump to hand expression (MD 0.02, 95% CI -0.67 to 0.71; P = 0.96, participants = 68). A study comparing a manual and large electric pump, reported sore nipples in 7% for both groups and engorgement in 4% using a manual pump versus 6% using an electric pump; and in one study no nipple damage was reported in the hand-expression group, and one case of nipple damage in each of the manual pump and the large electric pump groups.One study examined adverse effects on infants, however as the infants did not all receive their mothers' expressed milk, we have not included the results. Secondary outcomesThe quantity of expressed milk obtained was increased, in some studies by a clinically significant amount, in interventions involving relaxation, music, warmth, massage, initiation of pumping, increased frequency of pumping and suitable breast shield size. Support programmes and simultaneous compared to sequential pumping did not show a difference in milk obtained. No pump consistently increased the milk volume obtained significantly.In relation to nutrient quality, hand expression or a large electric pump were found to provide higher protein than a manual pump, and hand expression provided higher sodium and lower potassium compared to a large electric pump or a manual pump. Fat content was higher with breast massage when pumping; no evidence of difference was found for energy content between methods.No consistent effect was found related to prolactin change or effect on oxytocin release with pump type or method. Economic aspects were not reported. AUTHORS' CONCLUSIONS The most suitable method for milk expression may depend on the time since birth, purpose of expression and the individual mother and infant. Low-cost interventions including initiation of milk expression sooner after birth when not feeding at the breast, relaxation, massage, warming the breasts, hand expression and lower cost pumps may be as effective, or more effective, than large electric pumps for some outcomes. Variation in nutrient content across methods may be relevant to some infants. Small sample sizes, large standard deviations, and the diversity of the interventions argue caution in applying these results beyond the specific method tested in the specific settings. Independently funded research is needed for more trials on hand expression, relaxation and other techniques that do not have a commercial potential.

Abstract
BACKGROUND Recommendations on timing for introduction of allergenic foods in an infant diet have changed twice during the past decade. How families with different demographic characteristics implement the change has not been studied in the United States. OBJECTIVE To compare the age of introduction of allergenic foods between an urban Medicaid-based population and a suburban private insurance-based population in Cincinnati, Ohio. METHODS Two hundred parent surveys were distributed at well-child checkups between 4 and 36 months of age. Data were analyzed using distribution mapping to determine the difference in the age of introduction of infant formula, infant solids, whole cow's milk, eggs, peanut, and fish. Random forest analysis was used to determine the most important factors affecting the age of introduction for both populations. RESULTS There was no statistically significant difference in the age of infant solid introduction, but urban populations introduced allergenic foods earlier than suburban populations, with a statistically significant difference in the age of introduction of infant formula, whole cow's milk, eggs, peanut, and fish. The most important factor for the timing of all food introductions was the recommended age of introduction from health care professionals. CONCLUSION There is a difference between urban and suburban populations in the timing of introduction of allergenic foods but not in other infant solid foods. The reliance on physician recommendation for both populations supports the need for education and guidance to health care professionals on up-to-date guidance and recommendations.

Abstract
BACKGROUND Many women in developed countries do not meet their breastfeeding goals and wean early because of breast pain. OBJECTIVE This study aimed to describe clinical response to therapeutic breast massage in lactation (TBML) in the management of engorgement, plugged ducts, and mastitis. METHODS Breastfeeding women presenting with engorgement, plugged ducts, or mastitis who received TBML as part of their treatment were enrolled (n = 42). Data collected at the initial visit included demographic, history, and exam data pre-TBML and post-TBML. Email surveys sent 2 days, 2 weeks, and 12 weeks following the initial visit assessed pain and breastfeeding complications. A nested case control of engorged mothers (n = 73) was separately enrolled to compare engorgement severity. RESULTS Reasons for the visit included engorgement (36%), plugged ducts (67%), and mastitis (29%). Cases, compared to controls, were significantly more likely to have severe engorgement (47% vs 7%, P < .001). Initial mean breast pain level among those receiving TBML was 6.4 out of 10. Following TBML, there was significant improvement in both breast (6.4 vs 2.8, P < .001) and nipple pain (4.6 vs 2.8, P = .013). All women reported immediate improvement in their pain level. At the 12-week survey, 65% found the massage treatment very helpful. The majority of the women with a new episode of mastitis or plugged duct during the study follow-up found the techniques learned during the office visit very helpful for home management of these episodes. CONCLUSION In office, TBML is helpful for the reduction of acute breast pain associated with milk stasis. Mothers find TBML helpful both immediately in-office and for home management of future episodes.

Abstract
BACKGROUND There is controversy over whether a lack of breastfeeding is related to obesity development. OBJECTIVE We examined the effects of feeding different types of milk in late infancy on childhood growth. DESIGN A cohort of 1112 term, singleton children (born in 1992) from the Avon Longitudinal Study of Parents and Children, United Kingdom, were studied prospectively. Food records collected at 8 mo of age were used to define the following 5 mutually exclusive feeding groups on the basis of the type and amount of milk consumed: breast milk (BM), <600 mL formula milk/d (FMlow), ≥600 mL formula milk/d (FMhigh), <600 mL cow milk/d (CMlow), and ≥600 mL cow milk/d (CMhigh). Weight, height, and BMI were measured at 14 time points from birth to 10 y of age, and SD scores (SDSs) were calculated. Dietary energy and macronutrient intakes were available at 7 time points. RESULTS CMhigh children were heavier than were BM children from 8 mo to 10 y of age with weight differences (after adjustment for maternal education, smoking, and parity) ≥0.27 SDSs and an average of 0.48 SDSs. The maximum weight difference was at 18 mo of age (0.70 SDS; 95% CI: 0.41, 1.00 SDS; P = <0.0001). CMhigh children were taller at some ages (25-43 mo; P < 0.01) and had greater BMI SDSs from ≥8 mo of age (at 9 y of age; P = 0.001). FMhigh children were heavier and taller than were BM children from 8 to 37 mo of age. There were marked dietary differences between milk groups at 8 mo of age, some of which persisted to 18 mo of age. Adjustments for current energy and protein intakes did not attenuate the growth differences observed. CONCLUSIONS The feeding of high volumes of cow milk in late infancy is associated with faster weight and height gain than is BM feeding. The feeding of bottle-fed infants with high volumes of cow milk in late infancy may have a persisting effect on body habitus through childhood.

Abstract
OBJECTIVE To examine the effect of separation for early-onset sepsis (EOS) evaluations due to perinatal risk factors on breastfeeding practices among asymptomatic term newborns. METHODS This observational study included 692 nulliparous women with term, singleton uncomplicated pregnancies who intended to breastfeed and whose infants were well appearing at birth. We examined the rate of early breastfeeding initiation (within 2 hours of birth) and formula supplementation (in the first 24 hours) among this mother-infant cohort. RESULTS Asymptomatic infants separated for EOS evaluation within 2 hours of birth were more likely to have delayed initiation of breastfeeding (46.5% vs 12.5%; P<.001). This association remained significant when adjusted for potential confounders (adjusted odds ratio [aOR]: 5.5 [95% confidence interval (CI): 3.4-8.9]; P<.001). Among infants separated for EOS evaluation, mother-infant time together of ≤0.5 hour in the first 2 hours of life significantly delayed initiation (aOR: 8.9 [95% CI: 1.5-53.7]; P=.02) compared with infants spending >1.5 hours with their mothers. In bivariate analysis, both separation and initiation were associated with formula supplementation. After adjusting for confounders, only delayed initiation remained significantly associated with supplementation (aOR: 1.9 [95% CI: 1.1-3.5]; P=.03). CONCLUSIONS Early separation of asymptomatic infants from their mothers for EOS evaluation was significantly associated with delayed initiation of breastfeeding, which in turn was associated with increased formula supplementation in the first day of life. This unintended consequence of EOS evaluations among asymptomatic infants may be minimized by delaying early separation for performance of the evaluation, attempting breastfeeding initiation before separation, and/or applying more efficient criteria for identifying infants requiring evaluation.

Abstract
BACKGROUND This is an update of a 2008 Cochrane review. Breastfeeding is important. However, not all infants can feed at the breast and methods of expressing milk need evaluation. OBJECTIVES To assess acceptability, effectiveness, safety, effect on milk composition, contamination and cost implications of methods of milk expression. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (March 2014), CINAHL (1982 to March 2014), conference proceedings, secondary references and contacted researchers. SELECTION CRITERIA Randomised and quasi-randomised trials comparing methods at any time after birth. DATA COLLECTION AND ANALYSIS Three authors independently assessed trials, extracted data and assessed risk of bias. MAIN RESULTS This updated review includes 34 studies involving 1998 participants, with 17 trials involving 961 participants providing data for analysis. Eight studies compared one or more types of pump versus hand expression and 14 studies compared one type of pump versus another type of pump, with three of these studies comparing both hand expression and multiple pump types. Fifteen studies compared a specific protocol or adjunct behaviour including sequential versus simultaneous pumping protocols (five studies), pumping > 4 times per day versus < 3 times per day (one study), provision of a milk expression education and support intervention to mothers of preterm infants versus no provision (one study), provision of audio/visual relaxation to mothers of preterm infants versus no specific relaxation (two studies), commencing pumping within one hour of delivery versus between one to six hours (one study), breast massage before or during pumping versus no massage (two studies, of which one also tested a second behaviour), therapeutic touch versus none (one study), warming breasts before pumping versus not warming breasts (one study), combining hand expression with pumping versus pumping alone (one study) and a breast cleansing protocol versus no protocol (one study).There were insufficient comparable data on outcomes to undertake meta-analysis and data reported relates to evidence from single studies.Only one of the 17 studies examining maternal satisfaction/acceptability provided data in a way that could be analysed, reporting that mothers assigned to the pumping group had more agreement with the statement 'I don't want anyone to see me pumping' than mothers in the hand expression group and the statement 'I don't want anyone to see me hand expressing' (n = 68, mean difference (MD) -0.70, 95% confidence interval (CI) -1.25 to -0.15, P = 0.01), and that mothers found instructions for hand expression were clearer than for pumping (n = 68, MD 0.40, 95% CI 0.05 to 0.75, P = 0.02). No evidence of a difference was found between methods related to adverse effects of milk contamination (one study, n = 28, risk ratio (RR) 0.89, 95% CI 0.62 to 1.27, P = 0.51), (one study, n = 142 milk samples, MD 0.20, 95% CI -0.18 to 0.58, P = 0.30), (one study, n = 123 milk samples, MD 0.10, 95% CI -0.29 to 0.49, P = 0.61), (one study, n = 141 milk samples, MD -0.10, 95% CI -0.46 to 0.26, P = 0.59 ); or level of maternal breast or nipple pain or damage (one study, n = 68, MD 0.02, 95% CI -0.67 to 0.71, P = 0.96).For the secondary outcomes, greater volume was obtained when mothers with infants in a neonatal unit were provided with a relaxation tape or music-listening interventions to use while pumping, when the breasts was warmed before pumping or massaged while pumping.Initiation of milk pumping within 60 minutes of birth of a very low birthweight infant obtained higher mean milk quantity in the first week than the group who initiated pumping later. No evidence of difference in volume was found with simultaneous or sequential pumping or between pumps studied. Differences between methods was found for sodium, potassium, protein and fat constituents; no evidence of difference was found for energy content.No consistent effect was found related to prolactin change or effect on oxytocin release with pump type or method. Economic aspects were not reported.Most studies were classified as unclear or low risk of bias. Most studies did not provide any information regarding blinding of outcome assessment. Fifteen of the 25 studies that evaluated pumps or products had support from the manufacturers. AUTHORS' CONCLUSIONS The most suitable method for milk expression may depend on the time since birth, purpose of expression and the individual mother and infant. Low-cost interventions including early initiation when not feeding at the breast, listening to relaxation music, massage and warming of the breasts, hand expression and lower cost pumps may be as effective, or more effective, than large electric pumps for some outcomes. Small sample sizes, large standard deviations, and the diversity of the interventions argue caution in applying these results beyond the specific method tested in the specific settings.

Association between support from a health professional and breastfeeding knowledge and practices among obese women: evidence from the Infant Practices Study II. Womens Health Issues 2014; 24:641-8.

Abstract
BACKGROUND Obese women are less likely to initiate and continue breastfeeding. We described barriers to breastfeeding and examined the association between support from a health professional and breastfeeding knowledge and practices, by prepregnancy obesity status. METHODS Using data from the Infant Feeding Practices Study II, a cohort of U.S. women (N = 2,997), we performed descriptive statistics to describe barriers to breastfeeding by prepregnancy obesity status. We conducted multivariable regression to examine the association of breastfeeding support from a physician or nonphysician health professional with knowledge of the recommended duration of breastfeeding, breastfeeding initiation, and breastfeeding duration, and whether breastfeeding support had different associations with outcomes by prepregnancy obesity status. Average marginal effects were calculated from regression models to interpret results as percentage-point changes. FINDINGS Believing that formula was as good as breast milk was the most commonly cited reason for not initiating breastfeeding, and milk supply concerns were cited as reasons for not continuing breastfeeding. Physician breastfeeding support was associated with a 9.4 percentage-point increase (p < .05) in breastfeeding knowledge among obese women, although no increase was observed among nonobese women. Breastfeeding support from a physician or nonphysician health professional was associated with a significantly increased probability of breastfeeding initiation (8.5 and 12.5 percentage points, respectively) and breastfeeding for 6 months (12.5 and 8.4 percentage points, respectively), without differential associations by prepregnancy obesity. CONCLUSIONS Support for exclusive breastfeeding is an important predictor of breastfeeding initiation and duration among obese and nonobese women. Health educational interventions tailored to obese women might improve their breastfeeding initiation and continuation.

Abstract
OBJECTIVE The goal of this study was to identify the frequency of physician-diagnosed food allergies among 6-year-old US children and study the impact of exclusive breastfeeding and complementary food introduction on this frequency. METHODS Data were analyzed from children who participated in the Infant Feeding Practices Study II Year 6 Follow-Up Study (Y6FU). Children with probable food allergy (pFA) were defined as children with report of physician-diagnosed food allergy at age 6 years. Subgroups of pFA included children who were not diagnosed before 1 year of age (new pFA) and those with atopic risk factors (high risk). RESULTS Prevalence of total pFA in the Y6FU was 6.34%. The majority of these children had new pFA and high-risk factors. Higher maternal education, higher family income, family history of food allergy, and reported eczema before 1 year of age were significantly associated with higher odds of total or new pFA. Exclusive breastfeeding duration and timing of complementary food introduction were not significantly associated with total pFA. However, exclusive breastfeeding of ≥4 months compared with no breastfeeding was marginally associated with lower odds of new pFA (adjusted odds ratio: 0.51; P = .07); this effect was not observed with high-risk children. CONCLUSIONS Analysis of infant and maternal variables in the Y6FU cohort of US children revealed that socioeconomic and atopic factors were the main predictors of pFA at age 6 years. Exclusive breastfeeding of ≥4 months may have a preventive effect on development of pFA after 1 year of age in non high-risk children.

Abstract
There have been dramatic changes in timing of first exposure to solid foods for children over the last 40 years, ranging from exposure prior to 4 months of age for most infants in the 1960s, to guidelines recommending delaying solids until after 6 months of age introduced in the 1990s. Infant diet, specifically age of weaning and age at introduction of allergenic foods, has long been thought to play a role food allergy. However, controversy surrounding the relationship between timing of introduction of foods and development of food allergy has lead to a plethora of inconsistent infant feeding guidelines both between and within countries. The aims of this article were to discuss the history of changing guidelines for optimal timing of introduction of solids in general and allergenic solids in particular and the evidence (or lack thereof) underpinning recommendations at each of these time-points. We present the current clinical equipoise with regards to recently revised guidelines published almost simultaneously in the UK, US and Australia and argue that guideline modification about timing of introduction (both for high risk infants but also for the general population) will require careful review of emerging literature to provide a true evidence base to inform public health practice such as infant feeding guidelines.

Abstract
The period from birth to 24 mo (B-24) is a critical phase in which nutrient requirements for growth and development are high and several transitions in food consumption practices occur. A few large-scale national studies (eg, the Feeding Infants and Toddlers Study and Infant Feeding Practices Study) offer important insights into infant feeding practices and food consumption patterns in young children in the United States. The NHANES collects comprehensive cross-sectional data on the nutrition and health of Americans including infants and toddlers. This article describes the NHANES program and data from NHANES 1999-2010 on young children that are relevant for the B-24 Project. NHANES is a nationally representative survey of the noninstitutionalized US population that combines personal interviews with standardized physical examination and measurements via mobile examination centers. Data on infant feeding practices (breastfeeding and timing of introduction and nature of complementary foods), dietary intake (two 24-h recalls), and nutrient supplements are collected. Data on demographic characteristics, anthropometric measurements, biomarkers of nutrient status, food security, and participation in federal nutrition programs are also available. Data can be accessed online, downloaded, and pooled over several survey cycles, allowing examination of infant feeding practices, food and nutrient intakes, and nutritional status of Americans <2 y old. Subgroup analyses by race-ethnicity and income status are also possible. NHANES responds to evolving data needs, as feasible, in the context of the survey design, research priorities, and funding. It offers a vehicle for potentially gathering additional data on children <2 y to address the objectives of the B-24 Project in the future.

Abstract
Many lactating mothers participate in the workforce and have their infants cared for outside of their home, yet little is known about their child care providers' (CCPs') support of breastfeeding. This study examines the association between CCPs' breastfeeding support as reported by mothers at 3 months and mother's breastfeeding at 6 months. Infant Feeding Practices Study II, a longitudinal study, followed mothers of infants via mail questionnaires almost monthly from late pregnancy throughout the first year. This study consisted of 183 mothers who breastfed and had their infant in child care at 3 months and answered 5 questions regarding CCPs' supports. Total number of CCPs' support was a summary of responses to individual items and categorized into 3 levels (0-2, 3-4, or 5 total supports). Multiple logistic regressions examined how each breastfeeding support and total number were associated with breastfeeding at 6 months. Breastfeeding at 6 months was significantly associated with CCP support to feed expressed breast milk (AOR = 4.55; 95% CI = 1.09, 18.95) and allow mothers to breastfeed at the child care place before or after work (AOR = 6.23; 95% CI = 1.33, 29.16). Compared to mothers who reported fewer than 3 total supports, mothers who reported 5 supports were 3 times as likely to be breastfeeding at 6 months (AOR = 3.00, 95% CI = 1.11, 8.13). Our findings suggest that CCPs' breastfeeding support at 3 months, particularly feeding expressed breast milk and allowing mothers to breastfeed before or after work, may help mothers maintain breastfeeding at 6 months.

Abstract
BACKGROUND Controversies regarding infant feeding and childhood wheezing may result from insufficient differentiation among various feeding modes. OBJECTIVES We conducted prospective analyses of associations between the repeated ascertainment of feeding mode and wheezing in infancy. METHODS The Infant Feeding Practices Study II (2833 infants) provided data on coughing/wheezing episodes (CWEs) at 8 time points and feeding modes at 9 time points from months 1 to 12. Feeding modes were defined as direct breastfeeding, indirect breastfeeding (IBF, bottled breast milk), formula feeding (FF), and their combinations. In concurrent and delayed models using repeated measurements, the relative risks (RR) and their 95% confidence intervals (95% CI) of different feeding modes for CWEs were estimated. In the delayed models, only infants without symptoms were considered at risk for consequent CWE. RESULTS In a model with a 1-month delay, compared to direct breastfeeding, any other feeding mode showed a statistically significant risk for CWEs (IBF: RR = 1.69, 95% CI [1.05, 2.72]; FF: RR = 1.26, 95% CI [1.08, 1.47]; mixed breast feeding plus FF: RR = 1.25, 95% CI [1.01, 1.55]; and FF and direct breastfeeding: RR = 1.38, 95% CI [1.14, 1.68]). In a concurrent effect model, FF, the combination of FF and IBF, and mixed breastfeeding plus formula were risk factors (RR = 1.38, 95% CI [1.19, 1.59], RR = 1.83, 95% CI [1.27, 2.63], and RR=1.35, 95% CI [1.11, 1.65]; respectively). CONCLUSIONS Any mode of feeding that includes formula or bottled breast milk seems to be a moderate risk for cough or wheezing episodes in the first 12 months of life.

Abstract
Late-preterm infants (34 0/7-36 6/7 weeks gestation) are physiologically and developmentally immature at birth. The relationship between brain development and feeding is important since adequate oral intake is imperative to prevent feeding-related morbidity and mortality associated with being late preterm. One third of brain growth occurs in the last 6-8 weeks of gestation. The ontogeny of coordinated oral feeding appears to follow a chronological, predictable pattern in preterm neonates. This suggests that neurodevelopmental maturation, rather than experience or learned behavior, is largely responsible for feeding behaviors. The aim of this article is to provide a review of the literature that establishes the relationship between brain development and feeding in the late-preterm infant.

Abstract
BACKGROUND This is an update of a 2008 Cochrane review. Breastfeeding is important. However, not all infants can feed at the breast and methods of expressing milk need evaluation. OBJECTIVES To assess acceptability, effectiveness, safety, effect on composition, contamination and cost implications of methods of milk expression. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 January 2011), CINAHL (1982 to January 2011), conference proceedings, secondary references and contacted researchers. SELECTION CRITERIA Randomised and quasi-randomised trials comparing methods at any time after birth, and crossover trials commencing at least 28 days after birth. DATA COLLECTION AND ANALYSIS Three authors independently assessed trials, extracted data and assessed risk of bias. Data were checked for accuracy. MAIN RESULTS We included 23 studies with 10 studies (632 mothers) providing data for analysis.Mothers provided with a relaxation tape produced more milk than mothers who were not (mean difference (MD) 34.70 ml/single expression, 95% confidence interval (CI) 9.51 to 59.89, P = 0.007). A lower milk volume over six days was reported when comparing hand expression to the electric pump (standardised mean difference (SMD) -1.00 ml, 95% CI -1.64 to -0.36, P = 0.002); other studies of the same pump using different measures did not find a significant difference (12 to 36 hours postpartum SMD -0.38 cc, 95% CI -0.86 to 0.10, P = 0.12); day five postpartum SMD -0.62 ml/day, 95% CI -1.43 to 0.19, P = 0.13). No evidence of difference in volume was found with simultaneous or sequential pumping, or between manual and electric pumps studied. One study reported a higher sodium concentration in hand expressed milk compared to a manual pump (SMD 0.59 mmol/L, 95% CI 0.22 to 0.96, P = 0.002) and to an electric pump (SMD 0.70 mmol/L, 95% CI 0.32 to 1.09, P = 0.0003), and lower potassium concentration compared to a manual pump (MD -0.37 mmol/L, 95% CI 0.00 to 0.73, P = 0.05) or to an electric pump (SMD -0.32 mmol/L, 95% CI -0.69 to 0.06, P = 0.10). No evidence of difference was found for energy content, milk contamination or adverse effects. Reports of maternal views were not comparable. Economic aspects were not reported. AUTHORS' CONCLUSIONS The most suitable method for milk expression may depend on the time since birth, purpose of expression and the individual mother and infant. Low cost interventions including early initiation when not feeding at the breast, relaxation, hand expression and lower cost pumps may be as effective, or more effective, than large electric pumps for some outcomes. Small sample sizes, large standard deviations, small number of studies reviewed, and the diversity of the interventions argue caution in applying these results beyond the specific method tested in the specific settings.

Abstract
OBJECTIVE To test whether and how human lactation and breastfeeding practices can adapt to fulfill infant energy requirements during exclusive breastfeeding for 6 months. METHODS The First-Feed study was a longitudinal, observational field study to measure milk intake, energy intake (from the doubly labeled water method), anthropometry, and breastfeeding practices at 2 time points around 15 and 25 weeks of age. Fifty healthy exclusively breastfeeding mother-infant dyads were included from breastfeeding support groups in greater Glasgow, Scotland. Forty-seven completed (23 boys), and 41 were exclusively breastfed to 25 weeks of age. RESULTS Milk intakes were higher than literature values (923 [SD: 122] g/day, n = 36; and 999 [SD: 146] g/day, n = 33) at both 15 and 25 weeks of age (both P < .001) and increased significantly between time points (mean increase: 61 g/day [95% confidence interval: 23-99]; P = .003). Infant growth was normal compared with World Health Organization Child Growth Standards, and energy intakes were adequate compared with references for energy requirements. Behavioral data indicated no evidence of strain on breastfeeding practices. CONCLUSIONS Results of this prospective study reveal that when mothers are well supported and follow the World Health Organization recommendation on breastfeeding, milk intakes are high and increase over time, and there is adequate energy intake, normal infant growth, and no marked changes in breastfeeding practices. This new empirical evidence on adaptations during exclusive breastfeeding should help health professionals promote the initiation, duration, and exclusivity of breastfeeding.

Abstract
BACKGROUND Although premastication of food for weaning infants might have nutritional benefit, it is also associated with transmission of pathogens. We investigated premastication practices in Cape Town, South Africa, in lower socioeconomic status caregivers of infants below 2 years of age. METHODS A previously reported questionnaire was adapted for South African conditions. A convenience sample of infant caregivers was captured at public maternal/pediatric and HIV outpatient clinics and home visits. RESULTS We interviewed 154 caregivers, 92% of whom were the biological mothers (median age: 29). Of these, 70% were black, and 29% were colored. There were 106 (69%) caregivers who practiced premastication. The median age of infants who received premasticated food was 6 (interquartile range: 4-6) months. Forty-six (43%) infants were teething, and 44 (42%) had oral mucosal lesions while receiving premasticated food. Fifty-five (52%) caregivers reported an oral condition, mostly bleeding gums, mouth sores, and thrush, and 41 (39%) caregivers reported blood in the food. Premasticating caregivers had a significantly lower educational level than those caregivers who did not engage in this practice. Premastication practices were cultural (40%), habit (20%), and on mother's advice (75%). Reasons for premastication were to pretaste (68%), encourage eating (61%), estimate food temperature (85%), and homogenize food (60%). CONCLUSIONS Counselors and caregivers should be aware of the adverse effects of premastication. Education should include advice to avoid premastication and to seek health advice for oral conditions in the caregiver and child. More studies are needed to better define the extent and risks of premastication, including its possible role in increasing HIV-1 transmission.

Abstract
Women who are overweight or obese prepregnancy have shorter durations of producing milk (PM) and feeding breast milk exclusively (FBM-ex) than normal-weight women. We proposed that infant size at birth may reduce the negative associations between prepregnancy BMI and the durations of PM and FBM-ex. We used data from 2798 participants in the Infant Feeding Practices Study II and characterized infant size at birth as weight-for-gestational age (WGA). To assess possible mediation of the associations between maternal BMI and the durations of PM and FBM-ex by infant size at birth, Baron and Kenny's methods, the Sobel test, and bootstrapping were used. As expected, prepregnancy BMI was negatively associated (P < 0.0001) with the durations of PM and FBM-ex; it also was positively associated (P < 0.0001) with infant size at birth. However, infant WGA was positively associated (P < 0.0003) with the durations of PM and FBM-ex after adjustment for BMI. Thus, the negative associations between BMI and the durations of PM and FBM-ex were reduced by infant WGA; i.e. the statistical removal of infant size at birth increased the magnitude of the negative associations between BMI and the durations of PM and FBM-ex. Thus, the tendency of heavier mothers to deliver heavier infants reduces the true magnitude of the association between maternal prepregnancy BMI and shortened breastfeeding duration.

Abstract
BACKGROUND Breast-milk expression is widely practiced by American mothers, but little is known about who expresses milk, how expression affects breastfeeding, or whether overweight or obese women, who have less breastfeeding success than do normal-weight women, express milk differently. OBJECTIVES We investigated 1) whether breast-milk expression behavior differed by body mass index (BMI; in kg/m(2)) category and 2) whether the different breastfeeding behaviors of overweight (BMI: ≥25 and <30) and obese (BMI: ≥30) women resulted in different breastfeeding outcomes. DESIGN The subjects (n = 2288) provided information on BMI and breast-milk production, feeding, and expression in mail-in questionnaires as part of the Infant Feeding Practices Study II. Longitudinal and cross-sectional data were analyzed by using regression procedures adjusted for confounding. RESULTS Women of different BMI categories overall did not differ in whether, when, or why they expressed breast milk. Before 2 mo postpartum, however, obese women were more likely (P = 0.04, unadjusted) to try milk expression and were less likely (P = 0.01, unadjusted) to express milk successfully. In addition, overweight or obesity was associated (P < 0.03, unadjusted) with a shorter duration of breast-milk production only in women who never expressed milk. In overweight or obese women, those who ever expressed milk had longer durations of breastfeeding (P < 0.003, unadjusted) than did those who never expressed milk. CONCLUSIONS Breast-milk expression behaviors may differ by maternal BMI category only in the early postpartum period. In addition, breast-milk expression may reduce differences between BMI categories in the duration of breastfeeding and support longer durations of breastfeeding.

Abstract
Despite considerable evidence and effort, breastfeeding duration rates in resource-rich countries such as Australia remain below World Health Organization recommendations. The literature on the experience of breastfeeding indicates that women construct and experience breastfeeding differently depending upon their own personal circumstances and the culture within which they live. Breastfeeding has also been described as a deeply personal experience, which can be associated with 'moral' decision-making. The aim of this synthesis was to better understand the social phenomenon of breastfeeding by making the hidden obvious. Using a meta-ethnographic approach, we analysed the findings from 17 qualitative studies exploring women's experience of breastfeeding. Commonly used metaphors, ideas and phrases across the national and international qualitative studies were identified. Two overarching themes emerged. Breastfeeding was described in terms of 'expectation' and 'reality', while the emotional aspects of breastfeeding were expressed in 'connected' or 'disconnected' terms. The prevalence of health professionals and public health discourses in the language women use to describe their experience, and the subsequent impact of this on maternal confidence and self-assessment of breastfeeding are discussed. This synthesis provides insight into some of the subtle ways health professionals can build maternal confidence and improve the experience of early mothering.

Abstract
OBJECTIVES In November 2008, the American Academy of Pediatrics (AAP) doubled the recommended daily intake of vitamin D for infants and children, from 200 IU/day (2003 recommendation) to 400 IU/day. We aimed to assess the prevalence of infants meeting the AAP recommended intake of vitamin D during their first year of life. METHODS Using data from the Infant Feeding Practices Study II, conducted from 2005 to 2007, we estimated the percentage of infants who met vitamin D recommendations at ages 1, 2, 3, 4, 5, 6, 7.5, 9, and 10.5 months (n = 1952-1633). RESULTS The use of oral vitamin D supplements was low, regardless of whether infants were consuming breast milk or formula, ranging from 1% to 13%, varying by age. Among infants who consumed breast milk but no formula, only 5% to 13% met either recommendation. Among mixed-fed infants, 28% to 35% met the 2003 recommendation, but only 9% to 14% would have met the 2008 recommendation. Among those who consumed formula but no breast milk, 81% to 98% met the 2003 recommendation, but only 20% to 37% would have met the 2008 recommendation. CONCLUSIONS Our findings suggest that most US infants are not consuming adequate amounts of vitamin D according to the 2008 AAP recommendation. Pediatricians and health care providers should encourage parents of infants who are either breastfed or consuming <1 L/day of infant formula to give their infants an oral vitamin D supplement.

Abstract
OBJECTIVES Although some caregivers are known to premasticate food for infants, usually during the weaning period, HIV transmission has not been linked to this practice. We describe 3 cases of HIV transmission in the United States possibly related to this practice. PATIENTS AND METHODS Three cases of HIV infection were diagnosed in children at ages 9, 15, and 39 months; clinical symptomatology prompted the testing. A thorough investigation to rule out alternative modes of transmission was conducted. In addition, phylogenetic comparisons of virus from cases and suspected sources were performed by using the C2V3C3 or gp41 region of env and the p17 coding region of gag. RESULTS In 2 cases, the mothers were known to be infected with HIV, had not breastfed their children, and perinatal transmission of HIV had previously been ruled out following US HIV testing guidelines. In the third case, a great aunt who helped care for the child was infected with HIV, but the child's mother was not. All 3 children were fed food on multiple occasions that had been premasticated by a care provider infected with HIV; in 2 cases concurrent oral bleeding in the premasticating adult was described. Phylogenetic analyses supported the epidemiologic conclusion that the children were infected through exposure to premasticated food from a caregiver infected with HIV in 2 of the 3 cases. CONCLUSIONS The reported cases provide compelling evidence linking premastication to HIV infection, a route of transmission not previously reported that has important global implications including being a possible explanation for some of the reported cases of "late" HIV transmission in infants, so far attributed to breastfeeding. Until the risk of premastication and modifying factors (eg, periodontal disease) are better understood, we recommend that health care providers routinely query children's caregivers and expecting parents who are infected with HIV or at risk of HIV infection about this feeding practice and direct them to safer, locally available, feeding options.
