Are women with an unintended pregnancy less likely to breastfeed?

OBJECTIVE: To examine the association between unintended pregnancy and the initiation and duration of breastfeeding. STUDY DESIGN: This was a secondary data analysis of the 1995 Cycle 5 of the National Survey of Family Growth. POPULATION: We studied 6733 first singleton live births to US women aged 15 years to 44 years. OUTCOMES: Using the 1995 Institute of Medicine definitions, pregnancies were classified as intended or unintended; unintended pregnancies were further categorized as either mistimed or unwanted. We measured initiation of breastfeeding and duration of nonexclusive breastfeeding for at least 16 weeks. RESULTS: In this study, 51.5% of women never breastfed, 48.5% initiated breastfeeding, and 26.4% of all women continued breastfeeding for at least 16 weeks. US women with unwanted unintended pregnancies were more likely not to initiate breastfeeding (odds ratio [OR] = 1.76; 95% CI, 1.26-2.44) and more likely not to continue breastfeeding (OR = 1.69; 95% CI, 1.12-2.55) than women with intended pregnancies. White women with unwanted unintended pregnancies were more likely not to breastfeed than those with intended ones (initiation: OR = 2.50; 95% CI, 1.54-4.05; continuation: OR = 2.56; 95% CI, 1.34-4.87). This finding was not seen for black or Hispanic women. CONCLUSIONS: In the United States, women with unwanted pregnancies were less likely either to initiate or to continue breastfeeding than women with intended pregnancies. A strong inverse association between unwanted pregnancies and breastfeeding was observed only for white women. Education for women with unintended pregnancies may improve breastfeeding rates and subsequently, the health of women and infants.     

Association of Family and Health Care Provider Opinion on Infant Feeding with Mother's Breastfeeding Decision

In the United States, about 25% of women choose not to initiate breastfeeding, yet little is known about how opinions of individuals in a woman's support network influence her decision to breastfeed. In the 2005-2007 Infant Feeding Practices Study II, women completed questionnaires from the last trimester of pregnancy until 12 months postpartum. Mothers indicated prenatally their family members' and health care providers' opinion on how newborns should be fed: breastfed only, formula fed only, breast and formula fed, or no opinion/don't know. Breastfeeding initiation was determined by asking mothers around 4 weeks postpartum (n=2,041) whether they ever breastfed. Logistic regression was used to examine the association between mothers' perception of family members' and health care providers' opinion on how to feed the infant and the initiation of breastfeeding, adjusting for sociodemographic characteristics. Nearly 14% of mothers surveyed did not initiate breastfeeding. Mothers who believed their family members or health care providers preferred breastfeeding only were least likely not to initiate breastfeeding. Never breastfeeding was significantly associated with the following perceptions: the infant's father (odds ratio [OR]=110.4; 95% CI 52.0 to 234.4) or maternal grandmother (OR=15.9; 95% CI 7.0 to 36.0) preferred only formula feeding; the infant's father (OR=3.2; 95% CI 1.7 to 5.9) or doctor (OR=2.7; 95% CI 1.2 to 6.2) preferred both breast and formula feeding; and the infant's father (OR=7.6; 95% CI 4.5 to 12.7), maternal grandmother (OR=5.4; 95% CI 2.6 to 11.0), or doctor (OR=1.9; 95% CI 1.0 to 3.7) had no opinion/didn't know their feeding preference. The prenatal opinions of family members and health care providers play an important role in a woman's breastfeeding decisions after the infant's birth.     

Exploring the Concept of Positive Deviance Related to Breastfeeding Initiation in Black and White WIC Enrolled First Time Mothers

Positive deviance inquiry is effective in identifying advantageous health behaviors and improving health outcomes among disadvantaged resource-poor populations. The objective of this study was to apply the positive deviance concept to explore the characteristics of positive deviants for breastfeeding among WIC-enrolled first-time mothers in Louisiana. The cross sectional study included data on 2,036 WIC-enrolled first time mothers (52.6% black) from the LaPRAMs, 2000?C2004. Chi-square test was used to compare groups. Multivariable logistic regression was applied to calculate adjusted OR and 95% CI by breastfeeding initiation status. The average age was 21.3?years, 31.5% had less than 12?years of education, and 44.6% of the sample reported having initiated breastfeeding. Black mothers were less likely to initiate breastfeeding than their white counterparts (OR 0.39 (95% CI: 0.31, 0.48)). Among 641 WIC-enrolled first time mothers with less than 12?years of education, 28.4% were identified as positive deviants for breastfeeding initiation. Among the black mothers 19.8% were positive deviants compared to 40.3% of the white mothers. Breastfeeding in the hospital after delivery (P?<?0.0001) and having received help on how to breastfeed in the hospital (P?<?0.0001) were significantly associated with breastfeeding initiation in white and black mothers. In addition, the black positive deviants were more likely, OR 2.80 (95% CI: 1.20, 6.56) to have initiated breastfeeding if their baby was low birth weight. Breastfeeding practices shortly after delivery including assistance and education from staff in the hospital, are related to breastfeeding initiation among less educated WIC-enrolled mothers.     

The Association of Maternal Pre-pregnancy Body Mass Index with Breastfeeding Initiation

Recent evidence extends the health benefits of breastfeeding to include reduction of maternal body mass index (BMI) and childhood obesity. Since most women decide if they will breastfeed prior to pregnancy, it is important to understand, given the high population prevalence of obesity, if maternal underweight, overweight or obese status is associated with breastfeeding initiation. Population-based study. Florida resident birth certificate records. All live singleton births (2004–2009), excluding observations that lacked the primary outcomes of maternal pre-pregnancy BMI and breastfeeding initiation (final sample of 1,161,949 unique observations). Odds of initiating breastfeeding, adjusted by maternal and infant factors, stratified by pre-pregnancy BMI, categorized as underweight, normal, overweight and obese. Adjusting for the known maternal factors associated with breastfeeding initiation, underweight and obese women were significantly less likely to initiate breastfeeding than women with normal BMI, (adjusted odds ratio 0.87, 95 % confidence interval 0.85–0.89 for underweight women; 0.84, 95 % CI 0.83–0.85 for obese women). The magnitude of these findings did not significantly vary by race or ethnicity. Medicaid status and adherence to the Institute of Medicine’s 2009 pregnancy weight gain recommendations had only minor influences on breastfeeding initiation. Among adolescents, only underweight status predicted breastfeeding initiation; obesity did not. Underweight and obese women have significantly lower rates of breastfeeding initiation compared to women with normal pre-pregnancy BMI. Future studies need to address the health care, social, and physical barriers that interfere with breastfeeding initiation, especially in underweight and obese women, regardless of race, ethnicity or income.     

Maternal obesity is negatively associated with breastfeeding success among Hispanic but not Black women

Prepregnant overweight and obesity have been associated with failure to initiate and to sustain breastfeeding (BF) among Caucasian women; however, this relationship has not been studied among either Black or Hispanic women. Information extracted from medical records was used to examine the relationship between prepregnant overweight (BMI = 26.1-29.0 kg/m(2)) and obesity (BMI > 29.0 kg/m(2)) and the initiation and duration of BF among Black and Hispanic women living in an urban area. Among 587 Hispanic women, those who were obese were more likely than normal-weight women to feed formula and breast milk rather than to feed breast milk alone before discharge [odds ratio (OR): 1.9; 95% CI: 1.2-3.1]. Obese Hispanic women also had higher rates of discontinuation of exclusive BF [relative risk (RR): 1.5; 95% CI: 1.1-2.0]) and higher rates of discontinuation of BF to any extent (RR: 1.5; 95% CI: 1.1-2.1) during the first 6 mo postpartum. Among 640 Black women, prepregnant BMI was neither associated with differences in feeding pattern before discharge nor with differences in rates of discontinuation of exclusive or any BF. We concluded that among healthy women who attempt to breastfeed in the hospital, maternal prepregnant obesity was negatively associated with initiation and duration of BF in Hispanic women. In contrast, prepregnant BMI did not have the same association among Black women who attempted to breastfeed. We speculate that obesity may have a different biological meaning for BF success in Black women than it does in those who are Caucasian or Hispanic.     

Associations Between Peer Counseling and Breastfeeding Initiation and Duration: An Analysis of Minnesota Participants in the Special Supplemental Nutrition Program for Women,Infants, and Children (WIC)

Background Peer counseling (PC) has been associated with increased breastfeeding initiation and duration, but few analyses have examined the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) model for peer counseling or the continuation of breastfeeding from birth through 12 months postpartum. Objectives Identify associations between Minnesota WIC Peer Breastfeeding Support Program services and breastfeeding initiation and continuation. Methods Retrospective analysis of observational data from the Minnesota WIC program’s administrative database of women who gave birth in 2012 and accepted a PC program referral prenatally (n?=?2219). Multivariate logistic regression and Cox regression models examined associations between peer services and breastfeeding initiation and continuation of any breastfeeding. Results Among women who accepted referral into a PC program, odds of initiation were significantly higher among those who received peer services (Odds Ratio (OR): 1.66; 95% CI 1.19–2.32), after adjusting for confounders. Women who received peer services had a significantly lower hazard of breastfeeding discontinuation from birth through 12 months postpartum than women who did not receive services. (Hazard Ratio (HR) month one: 0.45; 95% CI 0.33–0.61; months two through twelve: 0.33; 95% CI 0.18–0.60). The effect of peer counseling did not differ significantly by race and ethnicity, taking into account mother’s country of origin. Conclusion for practice Receipt of peer services was positively associated with breastfeeding initiation and continued breastfeeding from birth through 12 months postpartum. Making peer services available to more women, especially in communities with low initiation and duration, could improve maternal and child health in Minnesota.     

Breastfeeding and breast cancer: a case-control study in Southern Brazil

To investigate the relationship between breastfeeding and breast cancer in Southern Brazil, a case-control design was employed, with two age-matched control groups. A total of 250 cases of breast cancer were identified in women from 20 to 60 years of age, with 1,020 hospital and community controls. The main study variables were occurrence of breastfeeding and duration of breastfeeding. A multivariate conditional logistic regression analysis was employed. According to the results, breastfeeding did not have a protective effect against breast cancer. The odds ratio (OR) for women who breastfed was 0.9 (95% CI: 0.8-1.2) compared to women who did not breastfeed. For women who breastfed for six months or less, the OR was 1.0 (95% CI: 0.6-1.8). In pre-menopausal women who breastfed for more than 25 months, the OR was 0.95 (95% CI: 0.5-3.5), and in post-menopausal women OR was 1.27 (95% CI: 0.5-3.1), compared to women who had not breastfeed.     

Chemical hair treatments and adverse pregnancy outcome among Black women in central North Carolina

Several studies suggest that toxic chemicals in hair products may be absorbed through the scalp in sufficient amounts to increase the risks of adverse health effects in women or their infants. This case-control study of 525 Black women from three counties in North Carolina who had delivered a singleton, liveborn infant examined whether exposure to chemicals used in hair straightening and curling increased the odds that the infant was preterm or low birth weight. Cases consisted of 188 preterm and 156 low birth weight births (for 123 women, their infant was both low birth weight and preterm). Controls were 304 women who delivered term and normal birth weight infants. Women who used a chemical hair straightener at any time during pregnancy or within 3 months prior to conception had an adjusted odds ratios (OR) of 0.7 (95% confidence interval (CI) 0.4-1.1) for preterm birth and 0.6 (95% CI 0.4-1.1) for low birth weight. Exposure to chemical curl products was also not associated with preterm delivery (adjusted OR = 0.9, 95% CI 0.5-1.8) or low birth weight (adjusted OR = 1.0, 95% CI 0.5-1.9). Despite this failure to find an association, continued search for risk factors to which Black women are uniquely exposed is warranted.     

Obese Mothers have Lower Odds of Experiencing Pro-breastfeeding Hospital Practices than Mothers of Normal Weight: CDC Pregnancy Risk Assessment Monitoring System (PRAMS), 2004–2008

Objectives This study examines the extent to which a mother’s pre-pregnancy body mass index (BMI) category is associated with her exposure to pro-breastfeeding hospital practices. Methods Data from the 2004–2008 CDC PRAMS were analyzed for three states (Illinois, Maine, and Vermont) that had administered an optional survey question about hospital pro-breastfeeding practices. Results Of 19,145 mothers surveyed, 19 % were obese (pre-pregnancy BMI ≥ 30). Obese mothers had lower odds than mothers of normal weight of initiating breastfeeding [70 vs. 79 % (unweighted), p < 0.0001]. Compared with women of normal weight, obese mothers had lower odds of being exposed to pro-breastfeeding hospital practices during the birth hospitalization. Specifically, obese mothers had higher odds of using a pacifier in the hospital [odds ratio (OR) 1.31, 95 % confidence interval (CI) (1.17–1.48), p < 0.0001] and lower odds of: a staff member providing them with information about breastfeeding [OR 0.71, 95 % CI (0.57–0.89), p = 0.002], a staff member helping them breastfeed [OR 0.69, 95 % CI (0.61–0.78), p < 0.0001], breastfeeding in the first hour after delivery [OR 0.55, 95 % CI (0.49–0.62), p < 0.0001], being given a telephone number for breastfeeding help [OR 0.65, 95 % CI (0.57–0.74), p < 0.0001], rooming in [OR 0.84, 95 % CI (0.73–0.97), p = 0.02], and being instructed to breastfeed on demand [OR 0.66, 95 % CI (0.58–0.75), p < 0.0001]. Adjusting for multiple covariates, all associations except rooming in remained significant. Conclusions Obesity stigma may be a determinant of breastfeeding outcomes for obese mothers. Breastfeeding support should be improved for this at-risk population.     

Breastfeeding Laws and Breastfeeding Practices by Race and Ethnicity

ObjectivesWe sought to examine breastfeeding practices by race and ethnicity in areas with and without eight specific breastfeeding laws.MethodsThe 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.FindingsRelative 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).ConclusionsBreastfeeding 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.     

WIC Participation and Breastfeeding in South Carolina: Updates from PRAMS 2009–2010

Few studies examined breastfeeding initiation and duration among mothers who were eligible for the Women Infants Children (WIC) program and did not participate. This study is sought to understand the role of WIC participation and poverty level in breastfeeding initiation and duration in South Carolina. The data came from the 2009–2010 South Carolina Pregnancy Risk Assessment Monitoring System (unweighted N = 1,796). All participants were classified as WIC participants, income-eligible non-WIC participants, and income-ineligible non-WIC participants. Logistic regression models were used to analyze the association between breastfeeding initiation and WIC participation. The Kaplan–Meier method and Cox proportional hazards models were used to determine whether the continuation of breastfeeding and hazards of discontinuing breastfeeding differed by WIC participation groups. In South Carolina, two out of three women (67.2 %) initiated breastfeeding. The breastfeeding initiation rate was higher among income-ineligible (84.0 %) and income-eligible (78.9 %) non-WIC participants than among WIC participants (55.5 %). Compared to WIC participants, both income-ineligible [odds ratio (OR) = 2.1, 95 % confidence interval (CI) 1.2–4.0] and income-eligible (OR = 2.6, 95 % CI 1.1–4.3) non-WIC participants were more likely to initiate breastfeeding. Among mothers who already initiated breastfeeding, after adjusting covariates, the hazard ratios for weaning within 34 weeks postpartum were not significantly different by WIC participation groups. This study confirmed WIC participants were less likely to initiate breastfeeding. Once initiated, WIC participation did not significantly impact breastfeeding duration in the early postpartum period. Poverty status may not play an important role in explaining disparities in breastfeeding initiation between WIC and non-WIC participants.     

Are breastfeeding rates higher among mothers delivering in Baby Friendly accredited maternity units in the UK?

BACKGROUND: The promotion and support of breastfeeding is a global priority with benefits for maternal and infant health, particularly in low-income and middle-income countries where its relevance for child survival is undisputed. However, breastfeeding rates are strikingly low in some higher-income countries, including the UK. Evidence to support the effectiveness of public health interventions to increase rates of breastfeeding initiation and duration in this setting is limited. We examined whether mothers were more likely to start and continue to breastfeed if they delivered in a UNICEF UK Baby Friendly accredited maternity unit, in a cohort with a high representation of disadvantaged and lower socioeconomic groups with traditionally low rates of breastfeeding. METHODS: We analysed maternally reported breastfeeding initiation and prevalence of any breastfeeding at 1 month for 17 359 singleton infants according to maternity unit Baby Friendly Initiative participation status at birth (accredited, certificated, or neither award). RESULTS: Mothers delivering in accredited maternity units were more likely to start breastfeeding than those delivering in units with neither award [adjusted rate ratio: 1.10, 95% confidence interval (CI) 1.05-1.15], but were not more likely to breastfeed at 1 month (0.96, 95% CI 0.84-1.09), after adjustment for social, demographic, and obstetric factors. Antenatal class attendance (1.14, 95% CI 1.11-1.17), vaginal delivery (1.05, 1.03-1.08), a companion at delivery (1.09, 1.04-1.16), and maternal post-partum hospital stay >24 h (1.06, 1.04-1.09) were also independently associated with breastfeeding initiation. CONCLUSIONS: Policies to increase the proportion of maternity units participating in the UNICEF UK Baby Friendly Initiative are likely to increase breastfeeding initiation but not duration. Other strategies are required in order to support UK mothers to breastfeed for the recommended duration.     

Breastfeeding Practices among Adolescent Mothers and Associated Factors in Bangladesh (2004–2014)

Optimal breastfeeding practices among mothers have been proven to have health and economic benefits, but evidence on breastfeeding practices among adolescent mothers in Bangladesh is limited. Hence, this study aims to estimate breastfeeding indicators and factors associated with selected feeding practices. The sample included 2554 children aged 0–23 months of adolescent mothers aged 12–19 years from four Bangladesh Demographic and Health Surveys collected between 2004 and 2014. Breastfeeding indicators were estimated using World Health Organization (WHO) indicators. Selected feeding indicators were examined against potential confounding factors using univariate and multivariate analyses. Only 42.2% of adolescent mothers initiated breastfeeding within the first hour of birth, 53% exclusively breastfed their infants, predominant breastfeeding was 17.3%, and 15.7% bottle-fed their children. Parity (2–3 children), older infants, and adolescent mothers who made postnatal check-up after two days were associated with increased exclusive breastfeeding (EBF) rates. Adolescent mothers aged 12–18 years and who watched television were less likely to delay breastfeeding initiation within the first hour of birth. Adolescent mothers who delivered at home (adjusted OR = 2.63, 95% CI:1.86, 3.74) and made postnatal check-up after two days (adjusted OR = 1.67, 95% CI: 1.21, 2.30) were significantly more likely to delay initiation breastfeeding within the first hour of birth. Adolescent mothers living in the Barisal region and who listened to the radio reported increased odds of predominant breastfeeding, and increased odds for bottle-feeding included male infants, infants aged 0–5 months, adolescent mothers who had eight or more antenatal clinic visits, and the highest wealth quintiles. In order for Bangladesh to meet the Sustainable Development Goals (SDGs) 2 and 3 by 2030, breastfeeding promotion programmes should discourage bottle-feeding among adolescent mothers from the richest households and promote early initiation of breastfeeding especially among adolescent mothers who delivered at home and had a late postnatal check-up after delivery.     

Breastfeeding Support Offered at Delivery is Associated with Higher Prevalence of Exclusive Breastfeeding at 6 Weeks Postpartum Among HIV Exposed Infants: A Cross-Sectional Analysis

Objective HIV-exposed uninfected infants are almost twice as likely to die compared to infants born to HIV-uninfected women. HIV-exposed uninfected children whose mothers are on ART and who are breastfed have the lowest risk of dying by 24 months of age. Interventions to improve breastfeeding among HIV-infected mothers are needed. We aimed to assess the association between support/counseling provided by healthcare workers following delivery and the rate of exclusive breastfeeding (EBF) at 6-week postpartum. Methods This is a secondary analysis of data collected as part of a trial to evaluate the effect of conditional cash transfers on retention in and uptake of PMTCT services. Between April 2013 and August 2014, newly diagnosed HIV-infected women,?≤?32 weeks pregnant, registering for antenatal care (ANC), in 89 clinics in Kinshasa, Democratic Republic of Congo, were recruited and followed through 6 weeks postpartum. At 6-week, participants were asked if they had given anything other than breastmilk to their infant in the 24 h preceding the interview (No?=?EBF) and whether a nurse or a doctor talked to them about breastfeeding after they gave birth (YES?=?received breastfeeding support/counseling). Logistic regression was used to estimate the odds ratios (OR) and 95% confidence intervals (CI) measuring the strength of the association between EBF and receiving breastfeeding support/counseling by a healthcare provider following delivery. Results Of 433 women enrolled, 328 attended a 6-week postpartum visit including 320 (97%) with complete information on EBF. Of those 320, 202 (63%) reported giving nothing other than breastmilk to their infant in the previous 24 h; 252 (79%) reported that a healthcare provider came to talk to them about breastfeeding following delivery. Mothers who reported receiveing breastfeeding support/counseling from a healthcare provider were more likely to exclusively breastfeed compared to those who did not (69% vs. 38%, OR 3.74; 95% CI 2.14–6.54). Adjustment for baseline sociodemographic characteristics did not change the association substantially, (adjusted OR 3.72; 95% CI 2.06–6.71). Conclusion for Practice Receipt of breastfeeding support/counseling from a healthcare provider after delivery among HIV-infected mothers in care at 6-weeks postpartum in Kinshasa almost quadrupled the odds of EBF.

     

The Association of State Law to Breastfeeding Practices in the US

We assessed the relationship between breastfeeding initiation and duration with laws supportive of breastfeeding enacted at the state level. We analyzed breastfeeding practices using the 2003–2010 National Health and Nutrition Examination Survey. We evaluated three measures of breastfeeding practices: Mother’s reported breastfeeding initiation, a proxy report of infants ever being breastfeed, and a proxy report of infants being breastfeed for at least 6 months. Survey data were linked to eight laws supportive of breastfeeding enacted at the state level. The most robust laws associated with increased infant breastfeeding at 6 months were an enforcement provision for workplace pumping laws [OR (95 % CI) 2.0 (1.6, 2.6)] and a jury duty exemption for breastfeeding mothers [OR (95 % CI) 1.7 (1.3, 2.1)]. Having a private area in the workplace to express breast milk [OR (95 % CI) 1.3 (1.1, 1.7)] and having break time to breastfeed or pump [OR (95 % CI) 1.2 (1.0, 1.5)] were also important for infant breastfeeding at 6 months. This research responds to breastfeeding advocates’ calls for evidence-based data to generate the necessary political action to enact legislation and laws to protect, promote, and support breastfeeding. We identify the laws with the greatest potential to reach the Healthy People 2020 targets for breastfeeding initiation and duration.     

Caffeine consumption during pregnancy and fetal growth.

BACKGROUND: The purpose of this study was to examine the association between maternal caffeine consumption and low birthweight, intrauterine growth retardation, and prematurity, adjusting for multiple confounders. METHODS: Data obtained from birth certificates and interviews on 1,230 women with singleton live births were analyzed to evaluate the potential influence of caffeine consumption during the first trimester on fetal growth. RESULTS: The crude odds ratio for intrauterine growth retardation in infants of women reporting heavy caffeine consumption (greater than 300 mg/day) was 3.86 (95% CI = 1.80, 8.40) which decreased to 2.90 (95% CI = 1.23, 6.87) after controlling for confounding factors. The adjusted odds ratio for low birthweight and heavy maternal caffeine consumption was also elevated (OR = 2.05; 95% CI = 0.86, 4.88). Women who reduced their caffeine intake from greater than 300 mg/day to less than that early in pregnancy had lower risks of delivering infants with either intrauterine growth retardation or low birthweight than women who continued to consume that amount. Preterm delivery appeared to be unrelated to caffeine consumption. CONCLUSIONS: Taken together with studies reporting similar findings, these results suggest that heavy caffeine consumption increases the risk for fetal growth retardation.     

Maternity Care Practices and Breastfeeding Experiences of Women in Different Racial and Ethnic Groups: Pregnancy Risk Assessment and Monitoring System (PRAMS)

Research shows that maternity care practices are important to promoting breastfeeding in the early post partum period; however, little is known about the association between maternity care practices and breastfeeding among different racial and ethnic groups. We examined the association between maternity care practices and breastfeeding duration to ??10?weeks overall and among various racial and ethnic groups using data from the Pregnancy Risk Assessment and Monitoring System (PRAMS). PRAMS is a state, population-based surveillance system that collects information on maternal behaviors. We used maternity care practices data from 11 states and New York City with response rates ??70% from 2004 to 2006. Multiple maternity care practices were examined and the analysis adjusted for demographic characteristics, participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), lifestyle, and infant variables. The outcome variable for multivariable analysis was breastfeeding duration to <10?weeks or ??10?weeks. PRAMS data show that 22.1% of women did not breastfeed, about 27.7% breastfed for <10?weeks and 50.2% breastfed for ??10?weeks. Breastfeeding patterns varied with white and Hispanic women reporting highest breastfeeding initiation and duration prevalence. Overall, practices positively associated with ??10 duration were: breastfeeding initiated within the first hour after birth (adjusted OR [AOR]?=?1.29; 95% CI: 1.16?C1.45); fed breast milk only (AOR?=?2.40; 95% CI: 2.15?C2.68); breastfed on demand (AOR?=?1.23; 95% CI 1.08?C1.40) and receiving telephone support (AOR?=?1.20; 95% CI: 1.03?C1.39). Maternity care practices associated with breastfeeding to ??10?weeks varied across three racial/ethnic groups. One practice, that of giving newborns breast milk only, was positively associated with breastfeeding duration of ??10?weeks across all three groups. Maternity care practices associated with breastfeeding continuation to ??10?weeks varied by race/ethnicity. For example: breastfeeding within the first hour, baby given a pacifier, and assistance from hospital staff, were significantly associated with breastfeeding duration among black and white women and not Hispanics. The practice of breastfeeding on demand was significantly associated with breastfeeding to ??10?weeks for black and Hispanic women and not for whites. Hospitals may want to examine the implementation of specific practices in relation to the cultural backgrounds of women to promote breastfeeding.     

Factors Associated with Intention to Breastfeed Among Low-Income,Inner-City Pregnant Women

Objectives: To examine the relationship between sociodemographic factors, maternal characteristics, and intention to breastfeed among low-income, inner-city pregnant women. Methods: English and Spanish speaking low-income women recruited from local Philadelphia health centers were surveyed at the time of their first prenatal care visit. At the time of the visit, respondents were asked whether or not they planned to breastfeed their infant. The responses of 2,690 women were included in these analyses. Multivariate logistic regression was used to assess the independent associations of race/ethnicity, nativity status, education, and other factors on the odds of intending to breastfeed. Results: About half (53%) of the respondents reported that they intended to breastfeed their infant. In adjusted logistic regression models, immigrant black (adjusted OR [aOR] 5.82; 95% confidence interval [CI] 3.86, 8.77), other Hispanic (who were predominantly foreign-born) (aOR 6.05; 95% CI 3.92, 9.33), and island-born Puerto Rican (aOR 3.48; 95% CI 2.04, 5.95) women were significantly more likely to report that they intended to breastfeed than non-Hispanic whites. Somewhat surprisingly, non-Hispanic, US-born African Americans in this low-income sample were more likely to report that they intended to breastfeed than non-Hispanic white respondents (aOR 1.59; 95% CI 1.20, 2.11). Lower education, not living with the baby's father, multiparous pregnancy, and smoking were negatively and independently associated with intention to breastfeed. Maternal age, household income, public housing, and depressive symptoms were not significant predictors of breastfeeding intention in adjusted multivariate models. Conclusions: Significant differences were documented in breastfeeding intention in our sample of low-income, inner-city women. Most notable was the higher likelihood of anticipated breastfeeding among our immigrant sub-groups when compared with non-Hispanic white women. An unexpected finding was the higher likelihood of anticipated breastfeeding among native-born, non-Hispanic African American women than among non-Hispanic white respondents. Because intentions are important predictors of future behavior, more focus needs to be directed towards breastfeeding promotion during the prenatal period and towards a better understanding of why some mothers intend to breastfeed while others do not.     

The relation between multiple births and maternal risk of breast cancer.

Data from two case-control studies conducted in New York State during 1982-1986 were used to examine the relation between multiple births and the maternal risk of breast cancer. The cases were 2,561 women between 20 and 79 years of age with a diagnosis of primary breast cancer. Controls (n = 2,616) were selected from driver's license files and matched to cases by year of birth and county of residence. The odds ratio for any multiple birth was 0.94 (95% confidence interval (CI) 0.56-1.56) in women less than 55 years of age and 0.95 (95% CI 0.62-1.46) in women aged 55-79 years. A previous study had shown a multiple last birth to be protective against breast cancer in women less than 55 years of age (odds ratio (OR) = 0.60, 95% CI 0.43-0.85). A decreased risk of breast cancer was also observed for this age group in the present study, but the magnitude of the effect was not as strong and the confidence interval included unity (OR = 0.85, 95% CI 0.43-1.68). A logistic model that controlled for age at first pregnancy, number of live births, age, and county of residence increased the odds ratio to 0.97 for a multiple last birth. The current study does not support an association between multiple births and maternal risk of breast cancer.     

Association Between Healthcare Provider Type and Intent to Breastfeed Among Expectant Mothers

Background The primary purpose of this study was to determine the association between type of healthcare provider delivering prenatal care and intent to exclusively breastfeed. Methods A self-report survey was administered to 455 expectant mothers. Logistic regression was performed to determine the association between prenatal care provider type [obstetrician; other primary care physician (family doctor/general practitioner/internist/or other physician); midwife/nurse midwife; more than one provider; and other] with intent to breastfeed (exclusive/non-exclusive). Results Having a midwife/nurse midwife as a prenatal care provider was associated with intent to breastfeed compared to having an obstetrician (OR 2.544, 95 % CI 1.385–4.675). There was no difference in intent between women with another primary care physician and an obstetrician. Women with another type of health care provider, no prenatal care from a health professional, or no knowledge of who is providing prenatal care were less likely to intend to breastfeed (OR 0.228, CI 0.068–0.766) as compared to those with an obstetrician. Discussion/Conclusions Provider type is associated with intent to breastfeed among pregnant women. Women’s intent to breastfeed is an important predictor of breastfeeding initiation, continuation, and duration that may be assessed by healthcare providers during the prenatal period. A consideration of what features of provider care are associated with improved breastfeeding outcomes and characteristics of women seeking prenatal care with midwives may serve to formulate future prenatal care policies and education during prenatal care visits.
