Multivariate analysis of state variation in breastfeeding rates in the United States

Structural Sexism and Breastfeeding in the United States, 2016-2021

INTRODUCTION

Recent studies demonstrate that structural sexism erodes women's health and impedes access to healthcare. This study extends this research to examine the relationship between structural sexism and breastfeeding initiation and duration in the United States.

METHOD

A multifaceted state-level structural sexism index was constructed and merged with responses from the 2016-2021 National Survey of Children's Health by state and child's birth year. For children ages six months to 5 years, the prevalence of being ever breastfed and breastfed for at least six months was measured across levels of structural sexism. Multivariable logistic regression analyzed the association of structural sexism with breastfeeding outcomes, net of individual and family characteristics.

RESULTS

Higher levels of structural sexism were associated with lower odds of breastfeeding initiation and lower odds of breastfeeding for at least six months net of family and child characteristics. In addition, sensitivity analyses show that variations in state breastfeeding laws did not explain these differences.

DISCUSSION

This study highlights structural sexism's role in limiting breastfeeding initiation and duration. Breastfeeding promotions and guidelines should consider the broader context of structural sexism.

In-Hospital Formula Supplementation in Appalachian Women Intending to Exclusively Breastfeed

OBJECTIVE

In-hospital formula supplementation places infants at risk for early breastfeeding cessation. The study's aim was to identify predictive and protective factors for in-hospital formula supplementation in individuals documented as wanting to exclusively breastfeed and residing in a geographic region with adverse social determinants of health and low breastfeeding rates. Additionally, we wished to determine if lactation consultation served as a protective factor against supplementation.

METHODS

In this cross-sectional study, we retrospectively reviewed 500 randomly selected charts of newborns born in a 12 month period at a regional tertiary care hospital. We included healthy, full-term neonates having a recorded maternal decision to exclusively breastfeed. Maternal-newborn dyad characteristics were compared between those exclusively breastfeeding and those with in-hospital formula supplementation.

RESULTS

Of the 500 charts, 70% of individuals desired to exclusively breastfeed. Overall, 41% of breastfed newborns were supplemented with formula before discharge, and 32% of women met with lactation consultants prior to supplementation. No statistically significant association was present between exclusive breastfeeding at discharge and meeting with a hospital lactation consultant (p = 0.55). When controlling for the confounders of maternal demographics and lactation consultation, significant associations with formula supplementation included Cesarean delivery (odd ratio: 2.08, 95% confidence interval: 1.04-4.16), primiparity (2.48, 1.27-4.87), and high school level of education (2.78, 1.33-5.78).

CONCLUSIONS

Maternal characteristics of high school level educational, primiparity, and Caesarean delivery place individuals at risk for in-hospital formula supplementation in individuals wishing to exclusively breastfeed. Addressing barriers to exclusive breastfeeding is essential to enhance maternal and newborn health equity.

Achieving healthy people 2030 breastfeeding targets in the United States: challenges and opportunities

OBJECTIVES

To estimate the national and states-specific gaps in breastfeeding rates in the United States for achieving the Healthy People 2030 (HP2030) targets, which are: 42.4% of infants to exclusively breastfeed through 6th months, and 54.1% of infants to breastfeed through 12th month of age.

STUDY DESIGN

The differences between the HP2030 breastfeeding targets and the respective state-specific baseline rates in the 2022 National Immunization Survey report for infants born in 2019 were computed.

RESULTS

The gaps in breastfeeding rates for achieving either of the two HP2030 targets varied greatly. Relative to their 2019 baseline estimates, 7 U.S. states need to increase breastfeeding rates between 100% and 207%, 27 states between 50% and 99%, 9 states and 2 territories between 20% and 49% and the remaining 7, between 0% and 19%.

CONCLUSIONS

Thirty-four of 50 (68%) states face huge gaps in achieving the HP2030 breastfeeding targets.

Racial Inequities in Breastfeeding Counseling Among Pregnant People Who Use Cannabis

We examined how breastfeeding advice in the context of cannabis use differed by race and ethnicity. Data from the 2017-2018 PRAMS (Pregnancy Risk Assessment Monitoring System) survey were used to assess differences in breastfeeding guidance related to cannabis use among 1,213 individuals who self-reported cannabis use 3 months before or during pregnancy. A multivariable logistic regression model was specified to examine the extent to which the odds of receiving prenatal advice against breastfeeding if using cannabis differed by self-reported race and ethnicity. We found that non-Hispanic Black people were four times more likely than non-Hispanic White people to be advised against breastfeeding if using cannabis (adjusted odds ratio 4.1, 95% CI 2.1-8.2). Pregnant non-Hispanic Black people were disproportionately advised not to breastfeed if using cannabis.

The role of state breastfeeding laws and programs on exclusive breastfeeding practice among mothers in the special supplemental nutrition program for Women, Infants, and Children (WIC)

BACKGROUND

It is unclear if state laws supporting breastfeeding are associated with exclusive breastfeeding (EBF) practice among low-income mothers participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). The main objectives of our study were to assess the relationship between such laws and EBF among WIC-participating mothers and to assess whether this association varied by employment status. We also assessed how mother's exposure to WIC breastfeeding consultation was associated with EBF.

METHODS

A cross-sectional study was conducted across seven WIC program locations (i.e., Georgia, Massachusetts, Nevada, Pennsylvania, Wisconsin, Wyoming, Chickasaw Nation) between July-August 2020. Data were collected using convenient sampling from each program location and surveys were administered electronically or on paper to WIC-participating mothers. We restricted our analysis to data from 1161 WIC-participating mothers with infants aged zero to five months old. Multivariable mixed models were used to estimate the relationship between our exposures of interest (i.e., number of laws supporting breastfeeding, employment-related breastfeeding laws, WIC breastfeeding consultation) and EBF, while controlling for potential confounders and accounting for clustering by program location. Effect modification by employment status was assessed on the additive and multiplicative scales.

RESULTS

Among WIC-participating mothers living in program locations with no employment-related breastfeeding laws, EBF was 26% less prevalent for employed mothers compared to unemployed mothers (adjusted prevalence ratios [aPR]: 0.74, 95% CI: 0.67,0.83). Among all mothers, a one-unit increase in laws supporting breastfeeding was not associated with EBF (aPR: 0.88, 95% CI: 0.71,1.10). However, among employed mothers, living in areas with more employment-related laws was associated with a higher prevalence of EBF (aPR: 1.43, 95% CI: 0.83, 2.44). Infants whose mothers received a WIC breastfeeding consultation had 33% higher prevalence of being exclusively breastfed compared to infants whose mothers did not receive a WIC breastfeeding consultation (aPR: 1.33, 95% CI: 1.05,1.70).

CONCLUSIONS

Infants whose WIC-participating mothers were employed, were less likely to be exclusively breastfed, but our effect modification analyses showed that laws supporting breastfeeding at the workplace may promote EBF among employed women. EBF was more prevalent among mothers who received a WIC breastfeeding consultation compared to those who did not receive such a consultation.

Towards a comprehensive breastfeeding-friendly workplace environment: insight from selected healthcare facilities in the central region of Ghana

Background

In the last three decades, Ghana has championed the objectives of Baby-Friendly Hospital Initiatives to provide pregnant women and nursing mothers with the skills and support systems necessary for attaining optimal breastfeeding. Yet, little is known in literature on how these intervention regimes practically promote breastfeeding-friendly work environment in healthcare facilities and their level of effectiveness. This study explores the extent to which healthcare facilities in Ghana’s Effutu Municipality provide breastfeeding-friendly workplace environment to breastfeeding frontline health workers.

Methods

A descriptive mixed-method approach was employed to collect data from fifty-four participants, comprising healthcare facility representatives and breastfeeding frontline health workers. A self-administered questionnaire with structured responses was administered to frontline health workers, followed by interview guides for representatives of hospital management. Thematic analysis was used to analyze interview responses. Responses to questionnaires were processed with SPSS version 23.0 and presented using frequencies and percentages.

Results

Three main themes emerged, namely, Standpoints on workplace breastfeeding support; Breastfeeding support, and Suggested future directions. Beyond this, six sub-themes emerged, including backings for workplace breastfeeding support; perceived benefits of breastfeeding support; factors of poor breastfeeding workplace support; maternity protection benefits; workplace support gaps, and awareness creation on benefits. Breastfeeding frontline health workers held that their hospitals have no breastfeeding policy (96%), no breastfeeding facility (96%), they do not go to work with baby (96%), but had 12 weeks maternity leave (96%) and worked half-day upon return to work (70%).

Conclusion

Health facilities in the study do not provide a breastfeeding-friendly work environment except for the privileges provided by the Labor Act and conditions of service. Continuous advocacy on breastfeeding workplace support and stakeholder engagement to build consensus on the mix of strategies suitable to cushion breastfeeding frontline health workers is recommended for optimal breastfeeding and improved productivity.

Integrating motherhood and employment: A 22-year analysis investigating impacts of US workplace breastfeeding policy

The United States has one of the lowest exclusive breastfeeding rates among high-income countries. Most experts agree that there is a lack of mother-friendly workplace policies compared to other countries. Since 1995, 25 states have implemented workplace breastfeeding legislation allowing mothers to express and store breast milk in the workplace. There is heterogeneity in policy enforceability where 17 states have weak enforceability while eight states have strict enforceability and require employers to offer provisions to breastfeed at the workplace. Using difference-in-differences methods, we examine the impact of this policy on state-level breastfeeding rates and assess how that impact differs with policy enforceability. We use data from the Centers for Disease Control on breastfeeding, supplementing with socio-economic data from the Panel Study of Income Dynamics, Current Population Survey, the US Census Bureau and several other datasets over 22 years from 1990 to 2011. We find that states with legislation experienced a 2.3-percentage point increase in breastfeeding rates compared to states without legislation while states with weak enforceability experienced a 3.1-percentage point increase compared to states without legislation. We also find that policies do not start to have an impact until 1-2 years after they were signed into law. Considering the recent assault on breastfeeding from the current administration, our study is a timely and important contribution that strengthens the evidence base for the health benefits of workplace breastfeeding policies.

Improving Drug Exposure Knowledge During Lactation: Quality Improvement Initiative in Low-Income Women

Objectives: To improve maternal knowledge on medication and substance usage during lactation through prenatal breastfeeding education and assess breastfeeding rates at 2-4 and 6-8 weeks postpartum. Study Design: This quality improvement initiative occurred between August 2016 and October 2017. Pregnant women without contraindications to breastfeeding receiving prenatal care at one of four prenatal sites in Florida were eligible. Enrolled women participated in a 1-hour interactive session consisting of basic breastfeeding education and medication or substance use during lactation. Demographic information, medical history, and pre/post breastfeeding knowledge scores were obtained. Regression analysis was utilized to evaluate the influence of medication usage on breastfeeding rates at 2-4 and 6-8 weeks postpartum. Results: The majority of participants (N = 121; median age = 26) were Hispanic (64%), unmarried (70%), and unemployed (60%). Approximately 25% were on medications other than supplements. Of those, one-third reported concerns regarding medication usage and infant safety during lactation. Knowledge regarding postpartum medications or substances and their breastfeeding compatibility increased significantly postintervention; however, women who were using medications at 2-4 and 6-8 weeks postpartum were 4 times as likely to mix feed or formula feed as compared with mothers not taking medications (adjusted odds ratio [OR] at 2-4 weeks = 3.693 confidence interval [95% CI]: 1.398-9.757) and adjusted OR at 6-8 weeks = 4.208 (95% CI: 1.009-17.548). Conclusions: This prenatal breastfeeding education targeting low-income women improved knowledge on medication usage and lactation. However, despite increasing breastfeeding knowledge, medication use appears to influence infant feeding behaviors at 2-4 and 6-8 weeks postpartum.

Breastfeeding Trends by Race/Ethnicity Among US Children Born From 2009 to 2015

IMPORTANCE

Large racial/ethnic disparities in breastfeeding are associated with adverse health outcomes.

OBJECTIVES

To examine breastfeeding trends by race/ethnicity from 2009 to 2015 and changes in breastfeeding gaps comparing racial/ethnic subgroups with white infants from 2009-2010 to 2014-2015.

DESIGN, SETTING, AND PARTICIPANTS

This study used data from 167 842 infants from the National Immunization Survey-Child (NIS-Child), a random-digit-dialed telephone survey among a complex, stratified, multistage probability sample of US households with children aged 19 to 35 months at the time of the survey. This study analyzed data collected from January 1, 2011, through December 31, 2017, for children born between 2009 and 2015.

EXPOSURES

Child's race/ethnicity categorized as Hispanic or non-Hispanic white, black, Asian, or American Indian or Alaskan Native.

MAIN OUTCOMES AND MEASURES

Breastfeeding rates, including ever breastfeeding, exclusive breastfeeding through 6 months, and continuation of breastfeeding at 12 months.

RESULTS

This study included 167 842 infants (mean [SD] age, 2.33 [0.45] years; 86 321 [51.4%] male and 81 521 [48.6%] female). Overall unadjusted breastfeeding rates increased from 2009 to 2015 by 7.1 percentage points for initiation, 9.2 percentage points for exclusivity, and 11.3 percentage points for duration, with considerable variation by race/ethnicity. Most racial/ethnic groups had significant increases in breastfeeding rates. From 2009-2010 to 2014-2015, disparities in adjusted breastfeeding rates became larger between black and white infants. For example, the difference for exclusive breastfeeding through 6 months between black and white infants widened from 0.5 to 4.5 percentage points with a 4.0% difference in difference (P < .001) from 2009-2010 to 2014-2015. In contrast, the breastfeeding differences between Hispanic, Asian, and American Indian or Alaskan Native infants and white infants became smaller or stayed the same except for continued breastfeeding at 12 months among Asians. For example, the difference in continued breastfeeding at 12 months between Hispanic and white infants decreased from 7.8 to 3.8 percentage points between 2 periods, yielding a -4.0% difference in difference (P < .001). Because of positive trends among all race/ethnicities, these reduced differences were likely associated with greater increases among white infants throughout the study years.

CONCLUSIONS AND RELEVANCE

Despite breastfeeding improvements among each race/ethnicity group, breastfeeding disparities between black and white infants became larger when breastfeeding improvements decreased even further among black infants in 2014-2015. The reduced breastfeeding gaps among all other nonwhite groups may be associated with greater increases among white infants. More efforts appear to be needed to improve breastfeeding rates among black infants.

Can environment or allergy explain international variation in prevalence of wheeze in childhood?

Asthma prevalence in children varies substantially around the world, but the contribution of known risk factors to this international variation is uncertain. The International Study of Asthma and Allergies in Childhood (ISAAC) Phase Two studied 8-12 year old children in 30 centres worldwide with parent-completed symptom and risk factor questionnaires and aeroallergen skin prick testing. We used multilevel logistic regression modelling to investigate the effect of adjustment for individual and ecological risk factors on the between-centre variation in prevalence of recent wheeze. Adjustment for single individual-level risk factors changed the centre-level variation from a reduction of up to 8.4% (and 8.5% for atopy) to an increase of up to 6.8%. Modelling the 11 most influential environmental factors among all children simultaneously, the centre-level variation changed little overall (2.4% increase). Modelling only factors that decreased the variance, the 6 most influential factors (synthetic and feather quilt, mother's smoking, heating stoves, dampness and foam pillows) in combination resulted in a 21% reduction in variance. Ecological (centre-level) risk factors generally explained higher proportions of the variation than did individual risk factors. Single environmental factors and aeroallergen sensitisation measured at the individual (child) level did not explain much of the between-centre variation in wheeze prevalence.

Impact of NICU admission on Colorado-born late preterm infants: breastfeeding initiation, continuation and in-hospital breastfeeding practices

OBJECTIVE

Compare breastfeeding initiation and continuation rates, and in-hospital breastfeeding practices, of late preterm infants (LPIs) cared for in a NICU versus those cared for exclusively in the nursery (non-NICU).

STUDY DESIGN

Using data from the 2009-2014 Colorado Pregnancy Risk Assessment Monitoring System (PRAMS), breastfeeding initiation, continuation, and in-hospital breastfeeding practices of NICU versus non-NICU LPIs (34 0/7 to 36 6/7 weeks gestation, n = 20,767) were analyzed, and multivariate models were created controlling for maternal and infant characteristics.

RESULTS

Mothers of NICU LPIs were equally likely to initiate breastfeeding (APR 1.0; 95% CI 0.95-1.06) but less likely to continue breastfeeding at 10 weeks (APR 0.86; 95% CI 0.76-0.99) compared to mothers of non-NICU LPIs. Mothers of NICU LPIs were less likely to breastfeed in the hospital, less likely to be told to feed infants on demand, and more likely to be given a breast pump during hospitalization.

CONCLUSIONS

There are significant differences in both breastfeeding continuation and several in-hospital breastfeeding practices for NICU versus non-NICU LPIs. Further research is needed so that targeted policies and programs can be developed to improve breastfeeding rates in this vulnerable population.

Reproductive risk factor associations with lobular and ductal carcinoma in the Carolina Breast Cancer Study

BACKGROUND

Invasive lobular breast tumors display unique reproductive risk factor profiles. Lobular tumors are predominantly Luminal A subtype, and it is unclear whether reported risk factor associations are independent of molecular subtype.

METHODS

Polytomous logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the associations between risk factors and histologic subtype [ductal (n = 2,856), lobular (n = 326), and mixed ductal-lobular (n = 473)] in the Carolina Breast Cancer Study (1993-2013). Three-marker immunohistochemical clinical subtypes were defined as Luminal A (ER+ or PR+/HER2-), Luminal B (ER+ or PR+/HER2+), Triple Negative (ER-/PR-/HER2-), and HER2+ (ER-/PR-/HER2+).

RESULTS

In case-case analyses compared to ductal, lobular tumors were significantly associated with lactation duration > 12 months [OR 1.86, 95% CI (1.33-2.60)], age at first birth ≥ 26 years [OR: 1.35, 95% CI: (1.03-1.78)], and current oral contraceptive use [OR: 1.86, 95% CI: (1.08-3.20)]. Differences in risk factor associations between ductal and lobular tumors persisted after restricting to Luminal A subtype.

CONCLUSIONS

Lobular tumors were associated with older age at first birth, increased lactation duration, and current oral contraceptive use. Etiologic heterogeneity by histology persisted after restricting to Luminal A subtype, suggesting both tumor histology and intrinsic subtype play integral parts in breast cancer risk.

Early feeding in child care in the United States: Are state regulations supporting breastfeeding?

Most women in the US are not meeting the recommendation of exclusively breastfeeding their infants for the first 6months of life. The child care environment can be especially influential in a mother's ability to continue breastfeeding after returning to employment. For this study, we reviewed child care regulations related to breastfeeding for centers and homes in all 50 states and the District of Colombia in late 2016, and compared them to 5 national standards. We coded regulations as either not meeting, partially meeting, or fully meeting each standard. We assessed correlations between number of regulations consistent with standards and 1) geographic census region and 2) last year of update. This study provides an update to a previous review conducted in 2012. No state met all 5 of the included standards, and only 2 states for centers and 1 state for homes at least partially met 4 of the 5 standards. More states had regulations consistent with standards encouraging general support for breastfeeding and requiring a designated place for mothers to breastfeed onsite. Number of regulations consistent with standards was associated with geographic census region, but not last year of update. States in the South had a greater number of regulations consistent with standards and states in the West had the fewest number of regulations consistent with standards. Overall support for breastfeeding at the state child care regulation level continues to be insufficient. States should improve child care regulations to include greater support for breastfeeding in child care facilities.

Association Between Type of Health Professional at Birth and Exclusive Breastfeeding

INTRODUCTION

Although benefits of breastfeeding for infants, women, and society are well established, breastfeeding rates in the United States remain below the Healthy People 2020 goals. Various factors are known to influence breastfeeding practices. Limited research has been conducted to examine the influence of type of birth attendant on exclusive breastfeeding.

METHODS

A cross-sectional analysis was conducted using data from the Infant Feeding Practices Study II collected between May 2005 and June 2007.

RESULTS

The study sample included 2026 women, aged 18 years or older. At discharge, 74.6% of women exclusively breastfed, and 27.6% exclusively breastfed at 3 months postpartum. Bivariate analysis showed a statistically significant association between type of health professional at birth and exclusive breastfeeding at discharge (P = .001) and 3 months postpartum (P < .001). After adjusting for potential confounders, the association between type of health professional at birth and exclusive breastfeeding at discharge was no longer significant. However, the odds of exclusive breastfeeding at 3 months postpartum were higher among women whose birth was attended by a midwife or nurse-midwife compared to those whose birth was attended by an obstetrician (odds ratio [OR], 1.87; 95% confidence interval [CI], 1.34-2.61; P < .001).

DISCUSSION

Exclusive breastfeeding continuation may be influenced by the type of health professional attending the birth. In addition to having a skilled workforce, health care professionals involved in perinatal care need to be educated and trained to promote and support exclusive breastfeeding as recommended. The complex and multifactorial nature of the maternal decision to exclusively breastfeed requires broader understanding of contextual factors.

Paid parental leave and family wellbeing in the sustainable development era

Background

The Sustainable development goals (SDGs) have the potential to have a significant impact on maternal and child health through their commitments both to directly addressing health services and to improving factors that form the foundation of social determinants of health. To achieve change at scale, national laws and policies have a critical role to play in implementing the SDGs’ commitments. One particular policy that could advance a range of SDGs and importantly improve maternal and infant health is paid parental leave.

Methods

This article analyzes literature on paid leave and related policies relevant to SDG 1 (poverty), SDG 3 (health), SDG 5 (gender equality), SDG 8 (decent work), and SDG 10 (inequality). In addition, this article presents global data on the prevalence of policies in all 193 UN Member States.

Results

A review of the literature finds that paid parental leave may support improvements across a range of SDG outcomes relevant to maternal and child health. Across national income levels, paid leave has been associated with lower infant mortality and higher rates of immunizations. In high-income countries, studies have found that paid leave increases exclusive breastfeeding and may improve women’s economic outcomes. However, factors including the duration of leave, the wage replacement rate, and whether leave is made available to both parents importantly shape the impacts of paid leave policies. While most countries now offer at least some paid maternal leave, many provide less than the 6 months recommended for exclusive breastfeeding, and only around half as many provide paternal leave.

Conclusions

To accelerate progress on the SDGs’ commitments to maternal and child health, we should monitor countries’ actions on enacting or strengthening paid leave policies. Further research is needed on the duration, wage replacement rate, and availability of leave before and after birth that would best support both child and parental health outcomes and social determinants of health more broadly. In addition, further work is needed to understand the extent to which paid leave policies extend to the informal economy, where the majority of women and men in low- and middle-income countries work.

Examining the Washington State Breastfeeding-Friendly Policy Development Process Using the Advocacy Coalition Framework

Objectives Breastfeeding promotion is increasingly recognized as a key public health strategy. Policies can promote breastfeeding by creating supportive environments and addressing challenges. In 2014, the Washington State legislature considered bills to create a voluntary recognition system for breastfeeding-friendly hospitals, clinics, worksites and childcare settings. These Breastfeeding-Friendly Washington (BFW) bills (SB 6298 and HB 2329) did not pass. Methods The purpose of this case study was to analyze the policy development process for the BFW bills using the Advocacy Coalition Framework. Data were collected through semi-structured interviews with key stakeholders in the state policy process, and document review. We used thematic analysis to identify deductive and inductive themes. Results Though all policy actors indicated general support for breastfeeding, two main coalitions (proponents and opponents) diverged in their support of the BFW bills as policy solutions to address barriers to breastfeeding. We conducted 29 interviews with mainly bill proponents, and 54 documents confirmed data about bill opponents. Proponents supported the bills given increasingly strong evidence of breastfeeding's benefits and that public policy could address environmental challenges to breastfeeding. Opponents saw the bills as government overreach into the private matter of choosing to breastfeed. Opposition to the bills came late in the session, and proponents felt opponents' messaging misconstrued the intent of the legislation. Conclusions for Practice Key learnings for developing breastfeeding-friendly state policies include analyzing differences between proponents' and opponents' beliefs, framing advocacy messages beyond individuals and health, expanding the coalition outside of traditional health entities, and anticipating the opposition.

A new performance measurement system for maternal and child health in the United States

Objective

The Title V Maternal and Child Health (MCH) Block Grant is the linchpin for US MCH services. The first national performance measures (NPMs) for MCH were instituted in 1997. Changing trends in MCH risk factors, outcomes, health services, data sources, and advances in scientific knowledge, in conjunction with budgetary constraints led the Maternal and Child Health Bureau (MCHB) to design a new performance measurement system.

Methods

A workgroup was formed to develop a new system. The following guiding principles were used: (1) Afford States more flexibility and reduce the overall reporting burden; (2) Improve accountability to better document Title V’s impact; (3) Develop NPMs that encompass measures in: maternal and women’s health, perinatal health, child health, children with special health care needs, adolescent health, and cross-cutting areas.

Results

A three-tiered performance measurement system was proposed with national outcome measures (NOMs), NPMs and evidence-based/informed strategy measures (ESMs). NOMs are the ultimate goals that MCHB and States are attempting to achieve. NPMs are measures, generally associated with processes or programs, shown to affect NOMs. ESMs are evidence-based or informed measures that each State Title V program develops to affect the NPMs. There are 15 NPMs from which States select eight, with at least one from each population area. MCHB will provide the data for the NOMs and NPMs, when possible.

Conclusions

The new performance measurement system increases the flexibility and reduces the reporting burden for States by allowing them to choose 8 NPMs to target, and increases accountability by having States develop actionable ESMs.

Significance

The new national performance measure framework for maternal and child health will allow States more flexibility to address their areas of greatest need, reduce their data reporting burden by having the Maternal and Child Health Bureau provide data for the National Outcome and Performance Measures, yet afford States the opportunity to develop measurable strategies to address their selected performance measures.

External Validation of Early Weight Loss Nomograms for Exclusively Breastfed Newborns

INTRODUCTION

Nomograms that show hour-by-hour percentiles of weight loss during the birth hospitalization were recently developed to aid clinical care of breastfeeding newborns. The nomograms for breastfed neonates were based on a sample of 108,907 newborns delivered at 14 Kaiser Permanente medical centers in Northern California (United States). The objective of this study was to externally validate the published nomograms for newborn weight loss using data from a geographically distinct population.

MATERIALS AND METHODS

Data were compiled from the Penn State Milton S. Hershey Medical Center located in Hershey, PA. For singleton neonates delivered at ≥36 weeks of gestation between January 2013 and September 2014, weights were obtained between 6 hours and 48 hours (vaginal delivery) or 60 hours (cesarean delivery) for neonates who were exclusively breastfeeding. Quantile regression methods appropriate for repeated measures were used to estimate 50th, 75th, 90th, and 95th percentiles of weight loss as a function of time after birth. These percentile estimates were compared with the published nomograms.

RESULTS

Of the 1,587 newborns who met inclusion criteria, 1,148 were delivered vaginally, and 439 were delivered via cesarean section. These newborns contributed 1,815 weights for vaginal deliveries (1.6 per newborn) and 893 weights for cesarean deliveries (2.0 per newborn). Percentile estimates from this Penn State sample were similar to the published nomograms. Deviations in percentile estimates for the Penn State sample were similar to deviations observed after fitting the same model separately to each medical center that made up the Kaiser Permanente sample.

CONCLUSIONS

The published newborn weight loss nomograms for breastfed neonates were externally validated in a geographically distinct population.

Predictors of breastfeeding initiation in Hong Kong and Mainland China born mothers

BACKGROUND

In recent years there has been a steady influx of immigrants into Hong Kong from Mainland China, where breastfeeding patterns differ. Studies in other regions have found substantial differences in breastfeeding rates between native-born and immigrant mothers. The purpose of this study was to examine factors associated with breastfeeding initiation in Hong Kong born and Mainland China born mothers living in Hong Kong.

METHODS

We used a multi-center cross-sectional study design and recruited 2761 new mothers from the postnatal wards of all eight public hospitals in Hong Kong that offer obstetric services. We assessed breastfeeding status as well as various socio-demographic, maternal and birth characteristics. Chi-square tests and multivariable logistic regression were used to identify the predictors of breastfeeding initiation in Hong Kong born and Mainland China born participants.

RESULTS

80.3 % of Hong Kong and 81.1 % of Mainland Chinese born women initiated breastfeeding. In the fully adjusted models, multiparity (Odds Ratio [OR] 0.53, 95 % CI 0.43-0.66) and maternal smoking (OR 0.29, 95 % CI 0.18-0.45) were strongly associated with failure to initiate breastfeeding in both Hong Kong and Mainland China born participants. In Hong Kong born mothers, participants with lower maternal education and those who had a cesarean section were significantly less likely to breastfeed. For Mainland China born mothers, paternal smoking (OR 0.70, 95 % CI 0.49-0.99) and having a pregnancy-related health problem (OR 0.60, 95 % CI 0.38-0.94) were both additional risk factors for not breastfeeding.

CONCLUSION

This study has identified predictors of breastfeeding initiation in Hong Kong and Mainland China born mothers. Given the current high breastfeeding initiation rates among both groups, antenatal breastfeeding education and promotion programmes need to specifically intervene with sub-groups of pregnant women at risk for not breastfeeding so that their efforts are more strategic and cost-effective.

Changes in Breastfeeding Attitudes in a Metropolitan Community in Tennessee

BACKGROUND

The Southern United States has low breastfeeding rates, particularly among African Americans. Breastfeeding rates are influenced by community attitudes and norms.

OBJECTIVE

This study aimed to examine changes in breastfeeding attitudes and demographic factors related to these attitudes.

METHODS

Cross-sectional data from a community-based survey, repeated annually from 2004 to 2008, were analyzed. Univariable analysis examined trends over time and log binomial regression estimated the strength of the association between year of the survey, demographic factors, and outcome responses related to the survey questions.

RESULTS

After adjusting for sex, race, marital status, age, and education, compared to 2004, 2008 respondents were 26% more likely to rate breastfeeding as extremely important compared to formula feeding (prevalence ratio [PR] = 1.26; 95% confidence interval [CI], 1.10-1.43). Similarly, 2008 respondents were 29% more likely to rate the importance of breastfeeding for long-term health as extremely important (PR = 1.29; 95% CI, 1.14-1.46). Comfort levels with breastfeeding outside the home also increased. Respondents to the 2008 survey were more likely to report that they were comfortable with a mother breastfeeding in their workplace (PR = 1.20; 95% CI, 1.11-1.31) and in a mall or restaurant (PR = 1.15; 95% CI, 1.06-1.26). After controlling for demographic factors, there were no significant differences in responses between African Americans and other races.

CONCLUSION

Despite significantly lower breastfeeding rates among African Americans, this analysis revealed significant positive changes in attitudes regarding breastfeeding between 2004 and 2008, regardless of race. These changes in attitude coincided with increased breastfeeding initiation rates, suggesting that federal, state, and local breastfeeding promotion efforts had an effect.

Promoting breastfeeding in child care through state regulation

Policies supporting breastfeeding vary by state, but little is known about the geographical aspects of this variation. This study describes state breastfeeding licensing and administrative regulations targeting child care settings, compares regulations with national standards, and examines the spatial patterning and clustering of these regulations throughout the United States (US). We compared regulations for child care centers (centers) and family child care homes (homes) with national standards for: (1) general breastfeeding support; (2) designated place for breastfeeding; (3) no solids before infants are four months of age; and (4) no formula for breastfed infants without parent permission. We scored state regulations as 0 = standard not addressed, 1 = standard partially addressed, and 2 = standard fully addressed. We considered each regulation individually, and also summed scores to provide an overall rating of regulations by state. We mapped regulations using geographic information systems technology, and explored overall and local spatial autocorrelation using global and local variants of Moran's I. Five states had regulations for centers and two for homes that addressed all four standards. Mean regulation scores were 0.35, 0.20, 0.98, 0.74 for centers, and 0.17, 0.15, 0.79, 0.58 for homes. Local Moran's I revealed that New York and Pennsylvania had substantially stronger regulations than their adjacent states, while Florida had weaker regulations than its neighbors. Overall, few states had regulations that met breastfeeding standards. We identified some patterns of spatial correlation, suggesting avenues for future research to better understand distributions of regulations across the US.

Facilitating working mothers' ability to breastfeed: global trends in guaranteeing breastfeeding breaks at work, 1995-2014

BACKGROUND

Mothers who work away from home tend to stop breastfeeding earlier than their nonworking counterparts due to workplace barriers. Barriers to breastfeeding discriminate against women and may lead to inequities in children's health outcomes. Guaranteeing paid breastfeeding breaks at work is 1 mechanism that can improve mothers' opportunity to breastfeed in the workplace.

OBJECTIVE

This study aimed to assess the trends in the share of countries guaranteeing breastfeeding breaks in the workplace and paid maternal leave that lasts until the infant is 6 months old (the World Health Organization recommended duration for exclusive breastfeeding), between 1995 and 2014.

METHODS

Legislation and secondary source data were collected and reviewed for 193 United Nations member states. Legislation was analyzed for content on breastfeeding breaks and maternal leave guarantees.

RESULTS

Fifty-one countries (26.7%) in 2014 did not guarantee breastfeeding breaks in any form and 4 countries provided only unpaid breaks or breaks that did not cover the first 6 months of life; since 1995, around 15 countries (10.2%) legislated for such a policy. In 2014, out of 55 countries that did not guarantee paid breastfeeding breaks for the first 6 months after birth, 7 countries guaranteed paid maternal leave for the same duration; 48 countries (25.1%) provided neither paid maternal leave nor paid breastfeeding breaks.

CONCLUSION

Progress in the number of countries guaranteeing breastfeeding breaks at work is modest. Adopting measures to facilitate breastfeeding at work can be a critical opportunity for countries to increase breastfeeding rates among the growing number of women in the labor force.

Breastfeeding laws and breastfeeding practices by race and ethnicity

OBJECTIVES

We sought to examine breastfeeding practices by race and ethnicity in areas with and without eight specific breastfeeding laws.

METHODS

The 2003 through 2010 National Health and Nutrition Examination Survey provides national breastfeeding practice information. We assessed eight breastfeeding laws before and after legislation was enacted and linked to population-based estimates of breastfeeding initiation and duration for children between birth and age one.

FINDINGS

Relative to Whites, Mexican-American infants were 30% more likely to breastfeed for at least 6 months in areas with laws protecting break-time from work to pump, and 20% more likely to breastfeed for at least 6 months in areas with pumping law enforcement provisions. Unexpectedly, five laws with the intention of supporting breastfeeding duration were significantly less helpful for African-American women relative to White women. African-American women were nearly half as likely to breastfeed for at least 6 months, relative to Whites in areas with provisions to provide break-time from work (adjusted odds ratio [AOR], 0.6; 95% confidence interval [CI], 0.5-0.8), private areas to pump at work (AOR, 0.6; 95% CI, 0.4-0.8), exemption from jury duty (AOR, 0.6; 95% CI, 0.4-0.9), awareness education campaigns (AOR, 0.5; 95% CI, 0.3-0.8), and pumping law enforcement provisions (AOR, 0.6; 95% CI, 0.5-0.8).

CONCLUSIONS

Breastfeeding laws influence African Americans and Mexican Americans differently than Whites. Examination of specific laws in conjunction with the interaction of known specific barriers for African-American mothers could help to achieve the Healthy People 2020 goals for breastfeeding.

Social and demographic determinants for breastfeeding in a rural, suburban and city area of South East China

Breastfeeding is a traditional practice in China, yet few studies have explored its current trend after socioeconomic reform. This study aims to characterize breastfeeding rates and possible associations with sociodemographic factors using a breastfeeding questionnaire administered to 1,385 mothers of 6-year-old children. Rates were lowest among city residents and negatively associated with parental and grandmother education levels as well as mothers' professional occupational status. These findings highlight the impact of urbanization on maternal and child health and the effect of marketing tactics for breast milk substitutes (BMS). Public health education promoting breastfeeding should target urban families, particularly those educated.

Neighborhood context and breastfeeding behaviors among urban mothers

BACKGROUND

Research consistently shows that breastfeeding behaviors vary according to individual-level sociodemographic characteristics, yet few studies examine contextual variations in breastfeeding.

OBJECTIVE

The purpose of this study is to examine the association between neighborhood context and breastfeeding among a sample of predominately unmarried urban mothers, a group with relatively low rates of breastfeeding.

METHODS

This study combines census tract information with data from 2 waves of the Fragile Families and Child Wellbeing Study (n = 4228) to predict the odds of initiating and sustaining breastfeeding.

RESULTS

Findings indicate that neighborhood socioeconomic composition, rather than racial or ethnic concentration, is associated with breastfeeding behaviors. More specifically, living in a highly educated neighborhood is associated with higher odds of initiating and sustaining breastfeeding.

CONCLUSION

These results suggest that the breastfeeding behaviors of urban mothers vary according to neighborhood educational context. Understanding how breastfeeding behaviors are shaped by one's neighborhood environment will allow public health initiatives to more effectively target vulnerable populations.

Extending the Peters-Belson approach for assessing disparities to right censored time-to-event outcomes

The Peters-Belson (PB) method was developed for quantifying and testing disparities between groups in an outcome by using linear regression to compute group-specific observed and expected outcomes. It has since been extended to generalized linear models for binary and other outcomes and to analyses with probability-based sample weighting. In this work, we extend the PB approach to right-censored survival analysis, including stratification if needed. The extension uses the theory and methods of expected survival on the basis of Cox regression in a reference population. Within the PB framework, among the groups to be compared, one group is chosen as the reference group, and outcomes in that group are modeled as a function of available predictors. By using this fitted model's estimated parameters, and the predictor values for a comparator group, the comparator group's expected outcomes are then calculated and compared, formally with testing and informally with graphics, with their observed outcomes. We derive the extension, show how we applied it in a study of incontinence in nursing home elderly, and discuss issues in implementing it. We used the 'survival' package in the R system to do computations.

Discursive constructions of breastfeeding in U.S. state laws

Previous research has identified several ways that breastfeeding is constructed in public discourses, each with consequences for breastfeeding attitudes, policies, and practices. Researchers analyzed discursive constructions of breastfeeding in U.S. state laws regarding breastfeeding in public to see if common representations were replicated in law and to identify patterns among states that used similar language. Results indicated that laws varied in the level of protection they offered, with the least protective laws decriminalizing breastfeeding in public and the most protective laws criminalizing interference with breastfeeding. The least protective states were located in the Western and North-Central regions, Republican-leaning, and less urban, whereas the most protective states were located in the New England and North-Central regions, Democrat-leaning, and more urban. Most states that fell on either end of this continuum had breastfeeding rates above the national average. Laws also varied in the level of regulation implied in their language, with the most regulative laws specifying that "a mother" can breastfeed "her baby" only in certain places and under certain conditions (discreetly). The most regulative states were located in the Southern and North-Central regions and had low breastfeeding rates, whereas the least regulative states were Western and had high breastfeeding rates.

Comparison of breast-feeding knowledge, attitudes, and beliefs before and after educational intervention for rural Appalachian high school students

OBJECTIVES

Breast-feeding rates in rural and southeastern regions of the United States are lower than national rates and Healthy People 2020 targets. The objectives of this study were to understand current breast-feeding knowledge, attitudes, and beliefs among rural southern Appalachian adolescents and to explore whether a high school educational intervention designed to address the five tenets (knowledge, attitudes, intentions, perceived behavioral control, and subjective norms) of the theory of planned behavior may be effective in increasing future rates of breast-feeding in this population.

METHODS

An educational session including an interactive game was developed and administered to occupational health science students during a single class period in two county high schools. A presurvey and a postsurvey administered 2 weeks after the intervention were completed by students. Pre- and postsurveys were analyzed using paired t tests and Cohen d and potential differences based on sex and grade were explored.

RESULTS

Both pre- and postsurveys were completed by 107 students (78%). Knowledge, attitudes about breast-feeding benefits, subjective norms, and intentions significantly improved following the intervention. Baseline knowledge and attitudes about breast-feeding benefits for mothers were low and demonstrated the greatest improvement.

CONCLUSIONS

Offering breast-feeding education based on the theory of planned behavior in a single high school class session was effective in improving student knowledge, attitudes, and beliefs about breast-feeding and intention to breast-feed.

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

A systematic review was undertaken to identify studies describing the global prevalence of breastfeeding up to two years of age or beyond and its effects on child growth and development. The MEDLINE and LILACS databases were searched without any language or date restrictions, retrieving 3,561 titles. All retrieved titles, 453 abstracts and 49 full-text articles were read. Articles with maximum breastfeeding duration of over two years were included. An analysis was carried out of 19 articles that met the inclusion criteria resulting in a combined prevalence of breastfeeding at two years of age of 33 % (95%CI: 0.23; 0.42). Increasing trends towards breastfeeding up to two years of age or beyond were observed in the past decades in South Asia. The six studies analyzing the effects of breastfeeding up to two years of age or beyond on child growth showed contradictory results. No association was found with child development. It is concluded that evidence on the medium-term effects of breastfeeding up to two years of age or beyond is scarce and contradictory. Hence, further research is needed regarding this practice.

Breastfeeding knowledge, attitudes, prior exposure, and intent among undergraduate students

BACKGROUND

Understanding breastfeeding knowledge, attitudes, and exposures among nonpregnant youth who are likely to be future parents may provide significant pathways to successfully increasing breastfeeding as the normal, accepted way of feeding infants. However, based on a recent review of the literature, only 3 studies have assessed these factors in nonpregnant, young adults in the United States in the past 10 years.

OBJECTIVE

The objective of this study was to gather more recent data regarding breastfeeding knowledge, attitudes, and prior exposure among undergraduate university students.

METHODS

This was a cross-sectional survey, conducted in November 2010. A convenience sample, consisting of undergraduates in attendance in 2 sections of an introductory nutrition class at a large research university, was used for this project (N = 248).

RESULTS

Breastfeeding knowledge was relatively good. However, overall breastfeeding attitudes were more neutral, which appeared to be explained by the belief that breastfeeding is painful, restrictive, and inconvenient, both in general and specifically for the working mother. Though support for breastfeeding in public was low, men were significantly less likely than women to believe it to be embarrassing or unacceptable. In addition, breastfeeding attitudes were more positive among older students and those who were breastfed as infants. Those who were breastfed as infants were also significantly more likely to intend to breastfeed future children.

CONCLUSIONS

Though this sample indicates good breastfeeding knowledge, attitudes were more neutral, and support for breastfeeding in public appears low. This finding is contradictory and warrants further exploration.

Do state breastfeeding laws in the USA promote breast feeding?

OBJECTIVES

Despite the passage of state laws promoting breast feeding, a formal evaluation has not yet been conducted to test whether and/or what type of laws may increase breast feeding. The enactment of breastfeeding laws in different states in the USA creates a natural experiment. We examined the impact of state breastfeeding laws on breastfeeding initiation and duration as well as on disparities in these infant feeding practices.

METHODS

Using data from the Pregnancy Risk Assessment Monitoring System, we conducted differences-in-differences models to examine breastfeeding status before and after the institution of laws between 2000 and 2008 among 326 263 mothers from 32 states in the USA. For each mother, we coded the presence of two types of state breastfeeding laws. Mothers reported whether they ever breast fed or pumped breast milk (breastfeeding initiation) and, if so, how long they continued. We defined breastfeeding duration as continuing to breast feed for ≥4 weeks.

RESULTS

Breastfeeding initiation was 1.7 percentage points higher in states with new laws to provide break time and private space for breastfeeding employees (p=0.01), particularly among Hispanic mothers (adjusted coefficient 0.058). While there was no overall effect of laws permitting mothers to breast feed in any location, among Black mothers we observed increases in breastfeeding initiation (adjusted coefficient 0.056). Effects on breastfeeding duration were in the same direction, but slightly weaker.

CONCLUSIONS

State laws that support breast feeding appear to increase breastfeeding rates. Most of these gains were observed among Hispanic and Black women and women of lower educational attainment suggesting that such state laws may help reduce disparities in breast feeding.

Maternal religious involvement and breastfeeding initiation and duration

Although religious involvement is associated with a number of beneficial health outcomes, few studies have investigated whether religious involvement is associated with breastfeeding behaviors. Our analyses of 2 waves of data from the Fragile Families and Child Wellbeing Study (n = 4,166) indicate that mothers who frequently attend religious services are more likely to initiate breastfeeding than are mothers who never attend services. Understanding religious variations in breastfeeding may allow public health officials to more effectively target vulnerable populations.

Racial/ethnic variation in breastfeeding across the US: a multilevel analysis from the National Survey of Children's Health, 2007

We examined whether differences across states in race/ethnicity-specific breastfeeding rates are due solely to state differences in individual factors associated with breastfeeding or additionally, certain state "contextual" factors. Using data from the 2007 National Survey of Children's Health, multilevel models examined whether state variability in race/ethnicity specific breastfeeding initiation and duration to 6 months were explained by (1) individual sociodemographic characteristics of women in states, and (2) an aggregate state measure of the availability of evidence-based maternity care services related to breastfeeding. Observed variability of race/ethnicity-specific breastfeeding rates was only minimally reduced after adjusting for sociodemographic characteristics (Median Odds Ratios (MOR), breastfeeding initiation: non-Hispanic White = 1.46, non-Hispanic Black = 2.26; Hispanic = 1.89. MOR, breastfeeding for 6 months: non-Hispanic White = 1.36, non-Hispanic Black = 1.84; Hispanic = 1.56). Overall variability in the degree of state gaps changed little in adjusted models (breastfeeding initiation: non-Hispanic Black σ(2) = 0.74, se 0.28, Hispanic σ(2) = 0.45, se 0.11; breastfeeding to 6-months: non-Hispanic Black σ(2) = 0.41, se 0.10, Hispanic σ(2) = 0.22, se 0.05). The measure of maternity care services was positively associated with breastfeeding overall but generally did not explain a substantial portion of between-state variability nor the overall variability in racial/ethnic gaps. Contextual sources of variation in state breastfeeding practices and disparities remain poorly understood. Differences in the socioeconomic makeup of states do not fully explain variability. The association of state breastfeeding rates and disparities with relevant policy and practice factors should be further investigated.

"That's not a beer bong, it's a breast pump!" representations of breastfeeding in prime-time fictional television

Breastfeeding has been recognized as one of the key determinant in one's future health. Yet although most people are aware of the benefits, many women do not breastfeed their babies past the first few months. These low rates can be partially explained by negative cultural attitudes toward breastfeeding, which have been reinforced by media messages. This research explored representations of breastfeeding in entertainment media-an area that has been overlooked. A textual analysis was conducted on 53 fictional television breastfeeding representations, ranging in genre and audience, from Beavis and Butthead to Criminal Minds. Findings indicate that breastfeeding depictions are generally positive, but limited in scope to educated, older, Caucasian women breastfeeding newborns, with little discussion about how to overcome problems. Extended breastfeeding and nursing in public were conveyed as socially unacceptable, making other characters uncomfortable, often within the same storylines that sexualized breasts. While the frequency of representations in recent years was encouraging, the narrow definition of the "normal" nursing experience excluded many types of women and breastfeeding experiences. And, by failing to address breastfeeding challenges and conveying that extended breastfeeding or nursing in public is abnormal or obscene, these depictions reinforce myths about the ease of breastfeeding and may discourage women from breastfeeding past the newborn phase, and outside the privacy of their homes. These portrayals may help explain why breastfeeding has not been "normalized," despite an international consensus that it is the best health choice for babies.

Academy of breastfeeding medicine founder's lecture 2011: inequalities and inequities in breastfeeding: an international perspective

Breastfeeding is the biological norm for infant feeding but is also a social construct. As such, its rates and practices are determined by the same social determinants that shape health inequalities and inequities. In the past 30 years, several reports have drawn attention to the changing pattern of breastfeeding inequalities across countries and population groups. Breastfeeding rates tend to fall and rise following a similar pattern everywhere, although at different times and speed. The role of women within families and societies, the routines of maternity hospitals and other healthcare services, and the pressure exerted by the baby food industry are among the factors that influence the time and speed of changes in breastfeeding rates and practices across countries and population groups. Inequities (i.e., inequalities considered unfair and avoidable by reasonable action) can be redressed by interventions for the protection, promotion, and support of breastfeeding. Evidence-based and quality-implemented support and promotion activities, if applied without an equity lens, may increase inequities. Activities for the protection of breastfeeding (e.g., implementation and enforcement of the International Code of Marketing of Breastmilk Substitutes; legislations, regulations, and policies to remove obstacles and barriers to good-quality breastfeeding support and to protect women and mothers in the workforce; elimination of obstacles and barriers to breastfeeding anywhere, anyhow, and anytime mothers want) apply to all women and are less dependent on take up by the target population. If well designed and enforced, protective interventions contribute to reducing inequalities and inequities and to delivering promotion and support activities more effectively.

Current state of US breastfeeding laws

This study systematically examined state-level laws protecting breastfeeding, including their current status and historical development, as well as identified gaps across US states and regions. The National Conference of State Legislatures summarised breastfeeding laws for 50 states and DC as of September 2010, which we updated through May 2011. We then searched LexisNexis and Westlaw to find the full text of laws, recording enactment dates and definitions. Laws were coded into five categories: (1) employers are encouraged or required to provide break time and private space for breastfeeding employees; (2) employers are prohibited from discriminating against breastfeeding employees; (3) breastfeeding is permitted in any public or private location; (4) breastfeeding is exempt from public indecency laws; and (5) breastfeeding women are exempt from jury duty. By May 2011, 1 state had enacted zero breastfeeding laws, 10 had one, 22 had two, 12 had three, 5 had four and 1 state had laws across all five categories. While 92% of states allowed mothers to breastfeed in any location and 57% exempted breastfeeding from indecency laws, 37% of states encouraged or required employers to provide break time and accommodations, 24% offered breastfeeding women exemption from jury duty and 16% prohibited employment discrimination. The Northeast had the highest proportion of states with breastfeeding laws and the Midwest had the lowest. Breastfeeding outside the home is protected to varying degrees depending on where women live; this suggests that many women are not covered by comprehensive laws that promote breastfeeding.

Mental health conditions among school-aged children: geographic and sociodemographic patterns in prevalence and treatment

OBJECTIVE

To explore geographic differences in diagnosed emotional and behavioral mental health conditions and receipt of treatment.

METHODS

Data are from the 2007 National Survey of Children's Health, a nationally representative, parent-reported, cross-sectional survey. Pediatric mental health conditions were identified using parents' responses to 3 questions regarding whether a health care provider had ever told them that their child had depression, anxiety problems, or behavioral or conduct problems. Parents also reported on past-year treatment or counseling by a mental health professional. State-level differences in condition prevalence were identified using unadjusted and adjusted prevalence estimates. Multivariate logistic regression assessed the odds of not receiving treatment by state and diagnoses.

RESULTS

Nearly 8% of children aged 6 to 17 years have ever been diagnosed with depression or anxiety, and 5.4% have ever been diagnosed with behavioral or conduct problems. State-level estimates of parent-reported depression or anxiety varied from 4.8% in Georgia to 14.4% in Vermont, while prevalence of behavioral problems ranged from 3.2% in California to 9.2% in Louisiana. Nearly 10% of all school-aged children and 53.1% of those ever diagnosed with either condition type received past-year treatment. The odds of receiving past-year parent-reported treatment did not differ by state of residence with the exception of Louisiana and Nevada: children ever diagnosed had approximately 2.5 times the odds of not receiving past-year treatment in these states.

CONCLUSION

The prevalence of parent-reported mental health disorders among children varies by geographic and sociodemographic factors, while receipt of treatment is generally dependent on sociodemographic and health-related factors.

Factors associated with exclusive breastfeeding in the United States

OBJECTIVES

To estimate the proportions of US infants who were breastfed exclusively for 6 months, according to characteristics of the mother, child, and household environment, and to compare associations between those characteristics and exclusive breastfeeding with associations between those characteristics and breastfeeding initiation.

METHODS

Data were obtained from the 2007 National Survey of Children's Health, a nationally representative, cross-sectional survey. Multivariate logistic regression was used to calculate the adjusted odds ratios for breastfeeding among all infants and for breastfeeding exclusively for 6 months among infants who had initiated breastfeeding. All analyses were limited to children aged 6 months through 5 years for whom breastfeeding data were available (N = 25 197).

RESULTS

Of the nearly 75% of children in the study who had ever been breastfed, 16.8% had been breastfed exclusively for 6 months. Non-Hispanic black children were significantly less likely to have ever been breastfed compared with their non-Hispanic white counterparts (adjusted odds ratio: 0.54 [95% confidence interval: 0.44-0.66]). However, no significant differences in the odds of exclusive breastfeeding according to race were observed. Children with birth weights of <1500 g were most likely to have ever been breastfed and least likely to have been breastfed exclusively. Maternal age was significantly associated with exclusive breastfeeding; however, maternal age was not associated with breastfeeding initiation.

CONCLUSIONS

In the United States, the prevalence of exclusive breastfeeding for 6 months remains low among those who initiate breastfeeding. Factors associated with breastfeeding exclusively for 6 months differ from those associated with breastfeeding initiation.

State breastfeeding worksite statutes.…breastfeeding rates…and.…

BACKGROUND

State worksite breastfeeding statutes are thought to play a role in increasing rates of breastfeeding duration, which remain below Healthy People 2010 goals. As of 2010 24 states including the District of Columbia had such worksite statutes. Of these only 18 required both break time and a site. This preliminary analysis assessed if infants born in states with worksite breastfeeding statutes had longer breastfeeding duration.

METHODS

Using the 2009 National Immunization Survey we analyzed infants comparing breastfeeding duration at 6 months with type of worksite breastfeeding statute in place, while adjusting for year enacted and other state characteristics (years since founding of state breastfeeding coalition, breastfeeding supportive hospital practices). Other covariates included maternal and infant characteristics. Only those infants whose mothers were at least 18 years old and who had not changed state of residence since birth were included (n=16,145).

RESULTS

Although requiring a site and/or break time for breastfeeding increased the likelihood of breastfeeding at 6 months (odds ratio, 1.20; 95% confidence interval, 1.07-1.35; p=0.002), after accounting for other factors this relationship remained positive but was not significant (adjusted odd ratio, 1.07; 95% confidence interval, 0.92-1.24). Because all mothers, not just those in or returning to the workforce, were included in the analysis this relationship could be underestimated. Breastfeeding at 6 months was associated with being from a state that had had a breastfeeding coalition for a longer period of time (adjusted odds ratio, 1.25; 95% confidence interval, 1.04-1.49; p<0001).

CONCLUSIONS

State worksite breastfeeding statutes alone may not directly affect breastfeeding duration. Analysis of breastfeeding duration using the multiple levels of the social-ecological model is a potentially useful approach to understanding the impact of state breastfeeding statutes. The impact of state breastfeeding coalitions warrants further study.

A qualitative study of attitudes toward public breastfeeding among young Canadian men and women

This research aims to explore, in qualitative terms, attitudes held by a sample of university-educated young men and women residing in New Brunswick and Nova Scotia about breastfeeding in public places. In sum, 20 women and 27 men between the ages of 18 and 23 participated in moderated single-sex focus groups that discussed breastfeeding, following a list of prepared questions and using photographs as discussion cues. Although participants uniformly stated that they desired their future children to be breastfed, 31 of 47 expressed restrictive attitudes toward exposure of the breast (eg, "should use washrooms," "okay if discreet") and breastfeeding in restaurants. Eight expressed positive unrestricted statements about breastfeeding in public spaces. Addressing widely held attitudes toward breastfeeding in public spaces, in addition to providing information about breastfeeding's health benefits, may be helpful in campaigns promoting breastfeeding.

Breastfeeding initiation in a rural sample: predictive factors and the role of smoking

The study objective was to identify demographic, medical, and health behavior factors that predict breastfeeding initiation in a rural population with low breastfeeding rates. Participants were 2323 women who experienced consecutive deliveries at 2 hospitals, with data obtained through detailed chart review. Only half the women initiated breastfeeding, which was significantly associated with higher levels of education, private insurance, nonsmoking and non-drug-using status, and primiparity, after controlling for confounders. Follow-up analyses revealed that smoking status was the strongest predictor of failure to breastfeed, with nonsmokers nearly twice as likely to breastfeed as smokers and with those who had smoked a pack per day or more the least likely to breastfeed. Findings reveal many factors placing women at risk for not breastfeeding and suggest that intervention efforts should encourage a combination of smoking cessation and breastfeeding while emphasizing that breastfeeding is not contraindicated even if the mother continues to smoke.

Working mothers, breastfeeding, and the law

Workplace barriers contribute to low rates of breastfeeding. Research shows that supportive state laws correlate with higher rates, yet by 2009, only 23 states had adopted any laws to encourage breastfeeding in the workplace. Federal law provided virtually no protection to working mothers until the 2010 enactment of the "reasonable break time" provision of the Patient Protection and Affordable Care Act. This provision nonetheless leaves many working mothers uncovered, requires break time only to pump for (not feed) children younger than 1 year, and exempts small employers that demonstrate hardship. Public health professionals should explore ways to improve legal support for all working mothers wishing to breastfeed. Researchers should identify the laws that are most effective and assist policymakers in translating them into policy.

Comfort with the idea of formula feeding helps explain ethnic disparity in breastfeeding intentions among expectant first-time mothers

OBJECTIVES

Little is known regarding modifiable factors that may explain sociodemographic disparities in breastfeeding rates among women in the United States. Using a mediation model approach, we examined the relative contributions of breastfeeding and formula feeding psychosocial factors in explaining disparities in breastfeeding intentions.

METHODS

We interviewed 532 expectant first-time mothers regarding exposure to breastfeeding by others (breastfeeding exposure), comfort with ideas of breastfeeding (breastfeeding comfort) and formula feeding (formula feeding comfort), and breastfeeding self-efficacy. We used logistic regression to evaluate the independent and mediating effects of these variables on strength of intention to fully breastfeed for 6 months (breastfeeding intention).

RESULTS

The ethnic distribution of the sample was 41% white, non-Hispanic; 27% Hispanic; 14% African-American; 12% Asian; and 6% mixed or other ethnicity. In the overall sample, formula feeding comfort, breastfeeding comfort, and breastfeeding self-efficacy all independently predicted breastfeeding intention (p < 0.0001), but formula feeding comfort had the largest effect: adjusted odds of stronger breastfeeding intention increased threefold for each 1-level decrease (among four levels) in formula feeding comfort. The unadjusted odds (95% confidence interval) of stronger breastfeeding intention were 0.37 (0.24-0.58) for African-American versus non-African-American women; African-American women had higher formula feeding comfort (2.08 [1.32-3.29]) but similar breastfeeding comfort, breastfeeding self-efficacy, and breastfeeding exposure. Formula feeding comfort mediated 37% of the disparity in breastfeeding intentions between African-American and non-African-American women.

CONCLUSIONS

Formula feeding comfort strongly predicted and substantially mediated ethnic disparity in breastfeeding intention. These results suggest that research and public health efforts aimed at increasing exclusive breastfeeding rates should include consideration of formula feeding attitudes.
