Neighborhood context and breastfeeding behaviors among urban mothers

Neighborhood Socioeconomic Status and Breastfeeding Initiation and Duration Among Primiparous Black Women

Background: Social determinants of health account for racial inequities in breastfeeding rates in the United States. There is a gap in the role of neighborhood socioeconomic status (NSES) as it relates to breastfeeding disparities. Methods: Using longitudinal data from the Black Women's Health Study, we assessed associations of NSES with breastfeeding initiation and duration in a cohort of primiparous U.S. Black women. We also explored associations within strata of important economic indicators, including education, occupation, and marital status. Results: Breastfeeding initiation (n = 2,705) increased with NSES quartile, from 75.2% in the lowest quartile to 88.3% in the highest quartile (p < 0.0001). Compared with women living in the highest NSES quartile, those in the lowest quartile had a 41% (odds ratio: 0.59 [95% confidence interval: 0.43, 0.81]) decreased odds of initiating breastfeeding. For breastfeeding duration (n = 2,172), women residing in NSES quartiles 1-3 were significantly less likely (p < 0.0001) to breastfeed (44.4%) for 6+ months compared with those living in the highest quartile (62.8%). Adjusted relative risks for those in quartiles 1-3 compared with 4 (highest) were 0.63 (0.45, 0.87), 0.50 (0.37, 0.68), and 0.64 (0.47, 0.86), respectively (p = 0.0001). There was no statistically significant evidence of effect modification by education, occupation, marital status, and region (Pinteraction = >0.05). Conclusion: Living in a lower NSES environment was associated with reduced breastfeeding initiation and duration compared with a higher NSES environment. Research is needed to understand the mechanisms by which neighborhood-level factors influence breastfeeding initiation and duration for Black women in the United States.

Neighborhood Disadvantage, Greenness, and Population Density as Predictors of Breastfeeding Practices: A Population Cohort Study from Finland

BACKGROUND

Many environmental factors are known to hinder breastfeeding, yet the role of the family living environment in this regard is still poorly understood.

OBJECTIVES

We used data from a large cohort to identify associations between neighborhood characteristics and breastfeeding behavior.

METHODS

Our observational study included 11,038 children (0-2 years) from the Southwest Finland Birth Cohort. Participant information was obtained from the Medical Birth Register and municipal follow-up clinics. Neighborhood socioeconomic disadvantage, greenness, and population density were measured for a period of 5 years prior to childbirth within the residential neighborhood on a 250 × 250-m grid. Any breastfeeding and breastfeeding at 6 months were the primary outcomes. Binary logistic regression models were adjusted for maternal health and socioeconomic factors.

RESULTS

Adjusted analyses suggest that mothers living in less populated areas were less likely to display any breastfeeding (OR: 0.46; 95% CI: 0.36, 0.59) and breastfeeding at 6 months (OR: 0.37; 95% CI: 0.34, 0.40). Mothers living in highly disadvantaged neighborhoods were less likely to display any breastfeeding if the neighborhood was less populated (OR: 0.54; 95% CI: 0.30, 0.95) but more likely to breastfeed at 6 months if the neighborhood was highly populated (OR: 3.74; 95% CI: 1.92, 7.29). Low greenness was associated with higher likelihood of any breastfeeding (OR: 3.82; 95% CI: 1.53, 9.55) and breastfeeding at 6 months (OR: 4.41; 95% CI: 3.44, 5).

CONCLUSIONS

Our results suggest that neighborhood characteristics are associated with breastfeeding behavior in Finland. Unravelling breastfeeding decisions linked to the living environment could help identify interventions that will allow the appropriate support for all mothers and infants across different environmental challenges.

Neighborhood Socioeconomic Disadvantage and Childhood Body Mass Index Trajectories From Birth to 7 Years of Age

BACKGROUND

The epidemic of increasing childhood overweight and obesity is a major global health concern, with local contextual factors identified as possible contributors. Robust research is needed to establish an evidence base supporting health policy decisions to reverse the trend. We aimed to examine the association between neighborhood socioeconomic disadvantage and trajectories of body mass index (BMI) from birth to age 7.

METHODS

The present study included 11,023 children born within the Southwest Finland Birth Cohort who were free of severe conditions affecting growth with adequate exposure and growth data. We obtained child growth data until school age from municipal follow-up clinics. We based cumulative childhood neighborhood socioeconomic disadvantage on the average annual income, unemployment, and level of education in a residential area defined using a geographic grid at a spatial resolution of 250 m by 250 m.

RESULTS

Cumulative neighborhood socioeconomic disadvantage was associated with distinct childhood BMI z score trajectories from birth to age 7. Despite being born in the lowest BMI z scores, children growing up in disadvantaged neighborhoods subsequently exhibited a trajectory of increasing BMI z scores starting at 4 years of age, ending up with a higher risk of overweight at the end of the follow-up (30%) as compared with children living in more affluent neighborhoods (22%). The corresponding risk of obesity was 5 % for those in affluent neighborhoods and 9 % and those in disadvantaged neighborhoods.

CONCLUSION

Cumulative exposure to neighborhood socioeconomic disadvantage is independently associated with unfavorable BMI development and obesity in childhood.

Social Determinants of Breastfeeding in the United States

Despite overall improvement in breastfeeding in the past 3 decades in the United States, significant and alarming social disparities persist. Adverse social determinants of health are increasingly recognized as root causes of social disparities in health outcomes, including breastfeeding initiation and continuation. We provide an overview of the evidence and mechanisms by which social determinants of health, including education, employment, food, neighborhood, and housing contribute to ongoing social disparities in breastfeeding in the United States, including current research gaps. We also review the intersection of social determinants of health with income, racism, and theory of planned behavior, a commonly used decision-making framework for breastfeeding promotion. Future interventions to address social determinants of breastfeeding should occur at the policy, community, organization, and individual levels.

Multilevel prenatal socioeconomic determinants of Mexican American children's weight: Mediation by breastfeeding

Objective: Mexican American (MA) children are more likely to grow up in poverty than their non-Hispanic/Latinx white peers and are at an elevated risk for early onset obesity. The current study evaluated the effects of prenatal family- and neighborhood-level disadvantage on children's weight and weight gain from 12 months through 4.5 years of age. Maternal breastfeeding duration was evaluated as a potential mechanism underlying the relation between multilevel disadvantage and weight. Methods: Data was collected from 322 low-income, MA mother-child dyads. Women reported the degree of family socioeconomic disadvantage and breastfeeding status. Neighborhood disadvantage was evaluated with census-level metrics. Children's weight and height were measured at laboratory visits. Results: Greater prenatal neighborhood disadvantage predicted higher child Body Mass Index (BMI) at 12 months, over and above family-level disadvantage; this effect remained stable through 4.5 years. Breastfeeding duration partially mediated the effect of neighborhood disadvantage on child BMI. Breastfeeding duration predicted child BMI at all timepoints. Conclusions: Maternal prenatal residence in a neighborhood with high concentrated disadvantage may place low-income, MA children at increased risk of elevated weight status during the first few years of life. Breastfeeding duration emerged as potentially modifiable pathway through which the prenatal neighborhood impacts children's early life weight.

Association of Social and Community Factors with U.S. Breastfeeding Outcomes

Objective: To explore, in a large, nationally representative U.S. sample of children, potential independent associations between social and community factors and breastfeeding outcomes, using the Social Ecological Model as a theoretical framework. Materials and Methods: A secondary data analysis of the 2011-2012 National Survey of Children's Health was conducted (N = 29,829). Multivariate logistic regression was performed to estimate associations between predictor variables (parental emotional support, neighborhood social support, neighborhood safety, neighborhood amenities, and medical home) and breastfeeding outcomes (breastfeeding initiation [BFI] and exclusive breastfeeding for 6 months [EBF6m]). For predictor variables reaching statistical significance in the adjusted models, we performed subgroup analyses by race-ethnicity. Results: After adjusting for individual- and family-level sociodemographic and maternal-child health factors, living in a neighborhood with 4 amenities was associated with 1.54 (95% confidence interval [CI] 1.06-2.23) times the odds of BFI, compared to children living in neighborhoods with no amenities. There was a negative association (adjusted odds ratio [aOR] 0.83; 95% CI 0.70-0.99) between neighborhood social support and BFI, although living in a supportive neighborhood was associated with 1.37 (95% CI 1.11-1.69) times the odds of EBF6m. There was a negative association (aOR 0.71; 95% CI 0.54-0.93) between perceived neighborhood safety and EBF6m. The observed associations differed by race-ethnicity. Conclusion: Community-level structural and social support factors influence breastfeeding outcomes, independent of previously described individual level sociodemographic factors, and the observed associations differ by race-ethnicity. These findings have implications for the development of "breastfeeding-friendly" communities and public policies.

Association of the Individual and Context Inequalities on the Breastfeeding: A Study from the Sicily Region

Despite the advantages of breastfeeding being widely recognized, the economic level can have an influence on breastfeeding rates, with rich women breastfeeding longer than poor in high-income countries. In Italy, socio-economic differences affect breastfeeding start and continuation among most deprived people, such as in Southern Italy. The objective of the study was to evaluate the prevalence of the initiation and continuation of exclusive breastfeeding and its association with the levels of socio-economic deprivation in Sicily. A prospective cohort study with a two-phase survey in three breastfeeding detection times was conducted. Overall, 1,055 mothers were recruited with a mean age of 31 years. Breastfeeding decreased from 86% during hospitalization to 69% at the first month and 42% at the sixth month, yet at the same time, exclusive breastfeeding increased from 34% to 38% during hospitalization to the first month and went down to 20.2% at the sixth month. The adjusted multivariate analysis showed no association with individual inequalities. On the other hand, the context inequalities had a significant association with the risk of not following exclusive breastfeeding in the deprived class (odds ratio (OR): 2.08, confidence interval (CI) 95% 1.01-4.27) and in the very deprived class (OR: 1.83, CI 95% 1.00-3.38) at the six-month survey. These results indicate that the context inequalities begin to emerge from the return home of the mother and the child.

Mediators of racial and ethnic disparity in mother's own milk feeding in very low birth weight infants

BACKGROUND

Despite high initiation rates for mother's own milk (MOM) provision, MOM feeding at discharge from the neonatal intensive care unit (NICU) drops precipitously and reveals a racial/ethnic disparity. This study sought to identify factors that (1) predict MOM feeding at NICU discharge, and (2) mediate racial/ethnic disparity in MOM feeding at discharge.

METHODS

Secondary analysis of prospective cohort study of 415 mothers and their very low birth weight infants. Variables were grouped into five categories (demographics, neighborhood structural, social, maternal health, and MOM pumping). Significant predictors from each category were entered into a multivariable logistic regression model.

RESULTS

Although 97.6% of infants received MOM feedings, black infants were significantly less likely to receive MOM feeding at discharge. Positive predictors were daily pumping frequency, reaching pumped MOM volume ≥500 mL/day by 14 days, and maternal age. Negative predictors were low socioeconomic status (SES) and perceived breastfeeding support from the infant's maternal grandmother. Low SES, maternal age, and daily pumping frequency mediated the racial/ethnic differences.

CONCLUSIONS

Multiple potentially modifiable factors predict MOM feeding at NICU discharge. Importantly, low SES, pumping frequency, and maternal age were identified as the mediators of racial and ethnic disparity. Strategies to mitigate the effects of modifiable factors should be developed and evaluated in future research.

Experiences of Racism and Breastfeeding Initiation and Duration Among First-Time Mothers of the Black Women's Health Study

BACKGROUND

Breastfeeding rates are lower for black women in the USA compared with other groups. Breastfeeding and lactation are sensitive time points in the life course, centering breastfeeding as a health equity issue. In the USA, experiences of racism have been linked to poor health outcomes but racism relative to breastfeeding has not been extensively investigated.

AIMS

This study aims to investigate the association between experiences of racism, neighborhood segregation, and nativity with breastfeeding initiation and duration.

METHODS

This is a prospective secondary analysis of the Black Women's Health Study, based on data collected from 1995 through 2005. Daily and institutional (job, housing, police) racism, nativity, and neighborhood segregation in relation to breastfeeding were examined. Odds ratios and 95% confidence intervals were calculated using binomial logistic regression for the initiation outcomes (N = 2705) and multinomial logistic regression for the duration outcomes (N = 2172).

RESULTS

Racism in the job setting was associated with lower odds of breastfeeding duration at 3-5 months. Racism with the police was associated with higher odds of breastfeeding initiation and duration at 3-5 and 6 months. Being born in the USA or having a parent born in the USA predicted lower odds of breastfeeding initiation and duration. Living in a segregated neighborhood (primarily black residents) as a child was associated with decreased breastfeeding initiation and duration relative to growing up in a predominantly white neighborhood.

CONCLUSION

Experiences of institutionalized racism influenced breastfeeding initiation and duration. Structural-level interventions are critical to close the gap of racial inequity in breastfeeding rates in the USA.

Breastfeeding practices in the United Kingdom: Is the neighbourhood context important?

Breastfeeding is an important public health issue worldwide. Breastfeeding rates in the United Kingdom, particularly for exclusive breastfeeding, are low compared with other OECD countries, despite its wide-ranging health benefits for both mother and child. There is evidence that deprivation in the structural and social organisation of neighbourhoods is associated with adverse child outcomes. This study aimed to explore whether breastfeeding initiation, exclusive breastfeeding for at least 3 months, and any type of breastfeeding for at least 6 months were associated with neighbourhood context measured by neighbourhood deprivation and maternal neighbourhood perceptions in a nationally representative U.K.

SAMPLE

A cross-sectional analysis was conducted using data from the Millennium Cohort Study. Logistic regression was carried out on a sample of 17,308 respondents, adjusting for individual- and familial-level socio-demographic characteristics. Neighbourhood deprivation was independently and inversely associated with breastfeeding initiation. Compared with the least deprived areas, the likelihood of initiating breastfeeding was 40% lower in the most deprived neighbourhoods (OR: 0.60, 95% CI [0.50, 0.72]). The relationship between both exclusive and any type of breastfeeding at 3 and 6 months respectively with neighbourhood deprivation after adjustment for potential confounders was not entirely linear. Breastfeeding initiation (OR: 0.78, 95% CI [0.71, 0.85]), exclusivity for 3 months (OR: 0.84, 95% CI [0.75, 0.95]), and any breastfeeding for 6 months (OR: 0.82, 95% CI [0.73, 0.93]) were each reduced by about 20% among mothers who perceived their neighbourhoods lacking safe play areas for children. Policies to improve breastfeeding rates should consider area-based approaches and the broader determinants of social inequalities.

Neighborhood Disadvantage and Neighborhood Affluence: Associations with Breastfeeding Practices in Urban Areas

Objective To estimate the associations between neighborhood disadvantage and neighborhood affluence with breastfeeding practices at the time of hospital discharge, by race-ethnicity. Methods We geocoded and linked birth certificate data for 111,596 live births in New Jersey in 2006 to census tracts. We constructed indices of neighborhood disadvantage and neighborhood affluence and examined their associations with exclusive (EBF) and any breastfeeding in multilevel models, controlling for individual-level confounders. Results The associations of neighborhood disadvantage and affluence with breastfeeding practices differed by race-ethnicity. The odds of EBF decreased as neighborhood disadvantage increased for all but White women [Asian: Adjusted odds ratio (AOR) 0.82 (95% confidence interval (CI) 0.69-0.97); Black: AOR 0.77 (95% CI 0.70-0.86); Hispanic: AOR 0.78 (95% CI 0.70-0.86); White: AOR 0.99 (95% CI 0.91-1.08)]. The odds of EBF increased as neighborhood affluence increased for Hispanic [AOR 1.19 (95% CI 1.08-1.31)] and White [AOR 1.12 (95% CI 1.06-1.18)] women only. The odds of any breastfeeding decreased with increasing neighborhood disadvantage only for Hispanic women [AOR 0.85 (95% CI 0.79-0.92)], and increased for White women [AOR 1.16 (95% CI 1.07-1.26)]. The odds of any breastfeeding increased as neighborhood affluence increased for all except Hispanic women [Asian: AOR 1.31 (95% CI 1.13-1.51); Black: AOR 1.19 (95% CI 1.07-1.32); Hispanic: AOR 1.08 (95% CI 0.99-1.18); White: AOR 1.30 (95% CI 1.24-1.38)]. Conclusions Race-ethnic differences in associations between neighborhood disadvantage and affluence and breastfeeding practices at the time of hospital discharge indicate the need for specialized support to improve access to services.

The Association Between Pregnancy Intention and Breastfeeding

BACKGROUND

Although breastfeeding is associated with proven benefits to both mother and child, there are many factors that influence a mother's decision to breastfeed. Pregnancy intentionality at the time of conception is associated with postpartum maternal behavior including breastfeeding. Research aim: We sought to understand how maternal and paternal pregnancy intentions were associated with breastfeeding initiation and duration in a nationally representative sample.

METHODS

We used a cross-sectional, retrospective study of the CDC National Survey of Family Growth data to examine the link between pregnancy intentionality and breastfeeding initiation and duration among women ages 15 to 44 years.

RESULTS

We found that whereas the mother's intention to have a child was a factor in how long she breastfed, the paternal intention to have a child predicted whether the mother breastfed at all. Additionally, Hispanic mothers were most likely to breastfeed and breastfed the longest of any other group. Age and education were also positive predictors of ever breastfeeding.

CONCLUSION

Understanding the father's and mother's attitudes toward the pregnancy and influence on breastfeeding intention is important for intervention planning.

Breastfeeding and Exposure to Past, Current, and Neighborhood Violence

Objectives Breastfeeding has short- and long-term health benefits for children and mothers, but US breastfeeding rates are suboptimal. Exposure to violence may contribute to these low rates, which vary by race/ethnicity. We studied: (1) whether patterns of violence exposure differ by race/ethnicity and (2) whether these patterns are associated with breastfeeding outcomes. Methods We conducted a secondary analysis of data drawn from self-report surveys completed by a convenience sample of low-income postpartum women (n = 760) in upstate New York. Latent class analysis was used to identify groups of women with similar responses to seven violence measures, including childhood physical and/or sexual violence, experience of partner violence during or just after pregnancy (physical, emotional, verbal), and neighborhood violence (perceived or by ZIP code). Logistic regression and survival analysis were utilized to determine if classes were associated with breastfeeding initiation, duration, and exclusivity, controlling for demographics. Results Exposure to at least one form of violence was high in this sample (87%). We identified 4 classes defined by violence exposure (combining current and historical exposures). Violence exposure patterns differed between racial/ethnic groups, but patterns were inconsistently associated with breastfeeding plans or outcomes. For White women, history of violence exposure increased the likelihood of earlier breastfeeding cessation. By contrast, among Black women, history of violence exposure increased the likelihood of having a breastfeeding plan and initiating breastfeeding. Conclusions for Practice Some differences between violence exposure classes are likely due to the correlation between race/ethnicity and socioeconomic status in the community studied. Additional studies are warranted to better understand how exposure to violence is related to breastfeeding and how best to support women making decisions about intention, initiation, and duration of breastfeeding.

Prenatal Exposure to Stressful Life Events and Infant Breastfeeding

BACKGROUND

Of the various barriers to breastfeeding, limited information is available on the relationship between prenatal stress and breastfeeding. This study investigates the association between prenatal stressful life event (SLE) exposure and breastfeeding initiation postpartum.

MATERIALS AND METHODS

Using Rhode Island Pregnancy Risk Assessment Monitoring System data from 2012 to 2014, SLE was defined as self-report of prenatal exposure to 14 predefined life events such as job loss or illness. Exposure to SLE was categorized by number and type of events. Multivariable logistic regression was performed to assess the relationship between SLE and breastfeeding initiation. Results accounted for complex survey design and were adjusted for maternal and infant characteristics (age, race, ethnicity, insurance, delivery type, parity, gestational age, birth weight for gestational age, and neonatal intensive care unit admission).

RESULTS

Among 3,353 respondents, 86% reported breastfeeding initiation, 74% reported exposure to ≥1 SLE, and 17% reported exposure to ≥4 SLE. Decreased odds of breastfeeding initiation were associated with prenatal exposure to ≥4 SLE (adjusted odds ratio [aOR] 0.67; 95% confidence interval [CI]: 0.48-0.95), emotional stressors (aOR 0.77; 95% CI: 0.61-0.98), and traumatic stressors (aOR 0.68; 95% CI: 0.50-0.91).

CONCLUSION

This study underscores the impact of exposure to prenatal SLE on breastfeeding initiation among postpartum women. Findings may assist providers in identifying at-risk women for anticipatory guidance to improve breastfeeding rates.

Barriers to Human Milk Feeding at Discharge of Very Low-Birthweight Infants: Evaluation of Neighborhood Structural Factors

BACKGROUND

Although 98% of mothers in our cohort initiated human milk (HM) provision for their very low-birthweight (VLBW) infants, fewer black infants received HM at neonatal intensive care unit (NICU) discharge than non-black infants. This study examined neighborhood structural factors associated with HM feeding at discharge to identify potential barriers.

MATERIALS AND METHODS

Sociodemographic and HM data were prospectively collected for 410 VLBW infants and mothers. Geocoded addresses were linked to neighborhood structural factors. Bivariate and multivariate logistic regression analyses were conducted for the entire cohort and racial/ethnic subgroups.

RESULTS

HM feeding at discharge was positively correlated with further distance from Women, Infants, and Children (WIC) office, less violent crime, less poverty, greater maternal education, older maternal age, greater infant gestational age, and shorter NICU hospitalization. Multivariate analysis demonstrated that only maternal race/ethnicity, WIC eligibility, and length of NICU hospitalization predicted HM feeding at discharge for the entire cohort. The interaction between access to a car and race/ethnicity significantly differed between black and white/Asian mothers, although the predicted probability of HM feeding at discharge was not significantly affected by access to a car for any racial/ethnic subgroup.

CONCLUSIONS

Neighborhood structural factors did not significantly impact HM feeding at discharge. However, lack of access to a car may be a factor for black mothers, potentially representing restricted HM delivery to the NICU or limited social support, and warrants further study.

Residential environment and breast cancer incidence and mortality: a systematic review and meta-analysis

BACKGROUND

Factors beyond the individual level such as those characterizing the residential environment may be important to breast cancer outcomes. We provide a systematic review and results of meta-analysis of the published empirical literature on the associations between breast cancer risk and mortality and features of the residential environment.

METHODS

Using PRISMA guidelines, we searched four electronic databases and manually searched the references of selected articles for studies that were published before June 2013. We selected English language articles that presented data on adult breast cancer incidence or mortality in relation to at least one area-based residential (ABR) independent variable.

RESULTS

We reviewed 31 eligible studies, and observed variations in ABR construct definition and measurement, study design, and analytic approach. The most common ABR measures were indicators of socioeconomic status (SES) (e.g., income, education, summary measures of several SES indicators or composite SES). We observed positive associations between breast cancer incidence and urbanization (Pooled RR for urban vs. rural: 1.09. 95% CI: 1.01, 1.19), ABR income (Pooled RR for highest vs. lowest ABR income: 1.17, 95% CI: 1.15, 1.19) and ABR composite SES (Pooled RR for highest vs. lowest ABR composite SES: 1.25, 95% CI: 1.08, 1.44). We did not observe consistent associations between any ABR measures and breast cancer mortality.

CONCLUSIONS

The findings suggest modest positive associations between urbanization and residential area socioeconomic environment and breast cancer incidence. Further studies should address conceptual and methodological gaps in the current publications to enable inference regarding the influence of the residential environment on breast cancer.
