Mexican-American Women's Lifelong Residence in the United States Is Associated with an Increased Risk of Gastroschisis: A Population-Based Study.

OBJECTIVE: To determine whether nativity is associated with abdominal wall defects among births to Mexican-American women. STUDY DESIGN: Using a cross-sectional, population-based design, stratified and multivariable logistic regression analyses were performed on the 2014-2017 National Center for Health Statistics live-birth cohort dataset of infants of US-born (n = 1 398 719) and foreign-born (n = 1 221 411) Mexican-American women. RESULTS: The incidence of gastroschisis was greater among births to US-born compared with Mexico-born Mexican-American women: 36.7/100 000 vs 15.5/100 000, RR = 2.4 (2.0, 2.9). US-born (compared with Mexico-born) Mexican-American mothers had a greater percentage of teens and cigarette smokers, P < .0001. In both subgroups, gastroschisis rates were greatest among teens and decreased with advancing maternal age. Adjusting for maternal age, parity, education, cigarette smoking, pre-pregnancy body mass index, prenatal care usage, and infant sex), OR of gastroschisis for US-born (compared with Mexico-born) Mexican-American women was 1.7 (95% CI 1.4-2.0). The population attributable risk of maternal birth in the US for gastroschisis equaled 43%. The incidence of omphalocele did not vary by maternal nativity. CONCLUSIONS: Mexican-American women's birth in the US vs Mexico is an independent risk factor for gastroschisis but not omphalocele. Moreover, a substantial proportion of gastroschisis lesions among Mexican-American infants is attributable to factors closely related to their mother's nativity.

Women's Economic Mobility and Small for Gestational Age Rates: The Effect of Paternal Early-Life Socioeconomic Position.

OBJECTIVE: To determine whether paternal early-life socioeconomic position (defined by neighborhood income) modifies the association of maternal economic mobility and infant small for gestational age (weight for gestational age < 10th percentile, SGA) rates. METHODS: Stratified and multilevel binomial regression analyses were executed on the Illinois transgenerational dataset of parents (born 1956-1976) and their infants (born 1989-1991) with appended U.S. census income information. Only Chicago-born women with an early-life residence in impoverished or affluent neighborhoods were studied. RESULTS: The incidence of impoverished-born women's upward economic mobility among births (n = 3777) with early-life low socioeconomic position (SEP) fathers was less than that of those (n = 576) with early-life high SEP fathers: 56% vs 71%, respectively, p < 0.01. The incidence of affluent-born women's downward economic mobility among births (n = 2370) with early-life low SEP fathers exceeded that of those (n = 3822) with early-life high SEP fathers: 79% vs 66%, respectively, p < 0.01. The adjusted RR of infant SGA for maternal upward (compared to lifelong impoverishment) economic mobility among fathers with early-life low and high SEP equaled 0.68 (0.56, 0.82) and 0.81 (0.47, 1.42), respectively. The adjusted RR of infant SGA for maternal downward (compared to lifelong residence in affluent neighborhoods) economic mobility among fathers with early-life low and high SEP were 1.37 (0.91, 2.05) and 1.17 (0.86, 1.59), respectively. CONCLUSIONS: Paternal early-life SEP is associated with maternal economic mobility (both upward and downward); however, it does not modify the relationship between maternal economic mobility and infant SGA rates.

The First-Year Mortality Rates of Singleton Infants Born at Term of US-Born and Foreign-Born Women: The Effect of Paternal Acknowledgment.

OBJECTIVE: To determine the whether a greater percentage of deaths of infants born at term among US-born (vs foreign-born) women is attributable to paternal nonacknowledgement. STUDY DESIGN: Using a cross-sectional population-based design, stratified and multivariable binomial regression analyses were performed on a subset of the 2017 National Center for Health Statistics linked live birth-infant death cohort dataset of singleton infants born at term (37-42 weeks) of US-born (N = 2 127 243) and foreign-born (N = 334 664) women. RESULTS: Infants of US-born women had a prevalence of paternal nonacknowledgement of 11.3% vs 7.5% for foreign-born women, P < .001. The infant mortality rate of term births to US-born women with paternal nonacknowledgment equaled 5.0/1000 vs 2.0/1000 for those with paternal acknowledgment; relative risk (RR) = 2.47 (2.31, 2.86). The infant mortality rate of term births to foreign-born women with paternal nonacknowledgment equaled 2.5/1000 vs 1.6/1000 for those with paternal acknowledgment, RR = 1.61 (1.24, 2.10). The adjusted (controlling for selected covariates) RR of first-year mortality of term births among US-born and foreign-born women with nonacknowledged (vs acknowledged) fathers equaled 1.43 (1.33, 1.54) and 1.38 (1.04, 1.84), respectively. The population-attributable risk percent of deaths in infants born at term for paternal nonacknowledgement among US-born and foreign-born women equaled 4.9% (246 deaths) and 2.8% (15 deaths), respectively. CONCLUSIONS: Paternal nonacknowledgement is associated with a 40% greater infant mortality rate among term births to US-born and foreign-born women; however, a greater proportion of first-year deaths among term births to US-born (vs foreign-born) women is attributable to paternal nonacknowledgment. These findings highlight the importance of a father's involvement in the outcomes of infants born at term.

Non-Hispanic White Women's Exposure to Decreased Neighborhood Income and Small for Gestational Age Births: A Population-Based Study.

BACKGROUND: The relationship between non-Hispanic White (NHW) women's decreased neighborhood income between early-life and adulthood, individual risk-status at delivery, and small for gestational age (weight for gestation < 10th percentile, SGA) rates is unknown. OBJECTIVE: To determine the extent to which NHW women's exposure to decreased neighborhood income is a risk factor for SGA births, and whether their own birth weight modifies this relationship. METHODS: Stratified and multilevel logistic regression analyses were executed on the Illinois transgenerational dataset of mothers (born 1956-1976) and their infants (born 1989-1991) with appended U.S. census income information. Only NHW women with an early-life residence in top income quartile Chicago neighborhoods were studied. RESULTS: NHW women (n = 4889) unexposed to decreased neighborhood income between early-life and adulthood had an SGA rate of 7.1%. In contrast, NHW women exposed to slightly (n = 5112), modestly (n = 2158), or severely (n = 339) decreased neighborhood income by the time of delivery had SGA rates of 8.2%, 10.8%, and 10.8%, respectively; RR (95% CI) equaled 1.2 (1.0-1.3), 1.5 (1.3-1.8) and 1.5 (1.1-2.1), respectively. The relationship between maternal exposure to modestly decreased neighborhood income and SGA rates was present only among former non-low birth weight (> 2500 g, non-LBW) mothers. In multilevel logistic regression models, the adjusted (controlling for age, parity, prenatal care usage, and cigarette smoking) OR of SGA birth for former low birth weight (< 2500 g, LBW) and non-LBW NHW women exposed to modestly (compared to no) decreased neighborhood income equaled 0.7 (0.4, 1.4) and 1.3 (1.1-1.6), respectively. CONCLUSIONS FOR PRACTICE: NHW women's exposure to modestly decreased neighborhood income is associated with an increased risk of SGA birth; this phenomenon is absent among former low birth weight women.

Excess Early (< 34 weeks) Preterm Rates Among Non-acknowledged and Acknowledged Low Socioeconomic Position Fathers: The Role of Women's Selected Pregnancy-Related Risk Factors.

OBJECTIVE: To determine the proportion of the excess early preterm birth (< 34 weeks, PTB) rates among non-acknowledged and acknowledged low socioeconomic position (SEP) fathers attributable to White and African-American women's selected pregnancy-related risk factors for PTB. METHODS: Oaxaca-Blinder decomposition methods were performed on the Illinois transgenerational birth-file of infants (1989-1991) and their parents (1956-1976) with appended U.S. census income information. The neighborhood income of father's place of residence at the time of his birth and at the time of his infant's birth were used to measure lifetime SEP. RESULTS: Among non-Latina White women, the early PTB rate for non-acknowledged (n = 3260), acknowledged low SEP (n = 1430), and acknowledged high SEP (n = 9141) fathers equaled 4.02%, 1.82%, and 1.19, respectively; p < 0.001. White women's selected pregnancy-related risk factors for PTB (inadequate prenatal usage, suboptimal weight gain, and/or cigarette smoking) were responsible for 19.3% and 41.2% of the explained disparities in early PTB rates for non-acknowledged and acknowledged low (compared to acknowledged high) SEP fathers, respectively. Among African-American women, the early PTB rate for non-acknowledged (n = 22,727), acknowledged low SEP (n = 4426), and acknowledged high SEP (n = 365) fathers equaled 6.72%, 4.34%, and 3.29%, respectively; p < 0.001. African-American women's selected pregnancy-related risk factors for PTB were responsible for 21.4% and 20.2% of the explained disparities in early PTB rates for non-acknowledged and acknowledged low SEP fathers, respectively. CONCLUSIONS: Non-Latina White and African-American women's selected pregnancy-related risk factors for PTB explain a significant percentage of excess early PTB rates among non-acknowledged and acknowledged low (compared to acknowledged high) SEP fathers.

Early and Late Preterm Birth Rates Among US-Born Urban Women: The Effect of Men's Lifelong Class Status.

OBJECTIVE: To ascertain the relation of men's lifelong class status (as measured by neighborhood income) to the rates of early (< 34 weeks) and late (34-36 weeks) preterm birth (PTB). METHODS: Stratified and multilevel, multivariable binomial regression analyses were computed on the Illinois transgenerational birth-file of infants (born 1989-1991) and their parents (born 1956-1976) with appended U.S. census income information. The median family income of men's census tract residence at two-time periods were utilized to assess lifelong class status (defined by residence in either the lower or upper half of neighborhood income distribution). RESULTS: In Cook County Illinois, the preterm rate for births (n = 8115) to men with a lifelong lower class status was twice that of births (n = 10,330) to men with a lifelong upper class status: 13% versus 6.0%, RR = 2.2 (2.0, 2.4). This differential was greatest in early PTB rates: 3.9% versus 1.4%, RR = 3.0 (2.5, 3.7). The relation of men's lifelong class status to both PTB components persisted among non-teens, married, college-educated, and non-Latina White women, respectively. The adjusted (controlling for maternal demographic characteristics) RR of early and late PTB for men with a lifelong lower (versus upper) class status were 1.4 (1.1, 1.9) and 1.2 (1.0, 1.4), respectively. The population attributable risk of early PTB for men's lifelong lower class status equaled 16%. CONCLUSIONS: Men's lifelong lower (versus upper) class status is a novel risk factor for early preterm birth regardless of maternal demographic characteristics. This intriguing finding has public health relevance.

Application of an Implementation Science Framework to Policies on Immediate Postpartum Long-Acting Reversible Contraception.

OBJECTIVES: Implementation science provides useful tools for guiding and evaluating the integration of evidence-based interventions with standard practice. The objective of our study was to demonstrate the usefulness of applying an implementation science framework-the Consolidated Framework for Implementation Research (CFIR)-to increase understanding of implementation of complex statewide public health initiatives, using the example of Medicaid immediate postpartum long-acting reversible contraception (LARC) policies. METHODS: We conducted semistructured telephone interviews with the 13 state teams participating in the Immediate Postpartum LARC Learning Community. We asked teams to describe the implementation facilitators, barriers, and strategies in 8 focus areas of the Learning Community. We audio-recorded and transcribed interviews and then coded each interview according to the domains and constructs (ie, theoretical concepts) of the CFIR. RESULTS: Cosmopolitanism (ie, networking with external organizations) was the most frequently coded construct of the framework. A related construct was networks and communications (ie, the nature and quality of social networks and formal and informal communications in an organization). Within the construct of cost, state teams identified barriers that were often unable to be overcome. Trialability (ie, ability to test the intervention on a small scale) and engaging champions (ie, attracting and involving persons who dedicate themselves to supporting the intervention in an organization) were among the most salient constructs of the framework and were the sources of many implementation strategies. CONCLUSIONS: State leaders and program staff members may benefit from considering the CFIR domains and constructs in the planning, implementation, and evaluation of complex statewide public health initiatives.

Low Birth Weight Among Infants Born to Black Latina Women in the United States.

Objectives To explore associations between race, nativity, and low birth weight (LBW) among Latina and non-Latina women, with special attention to the Black Latina subgroup. Methods Using US natality data from 2011 to 2013, we designed a population-based study to compare LBW (< 2500 g) rates across six groups of women with self-identified race (N = 7,865,264)-White and Black Latina, foreign-born and US-born; non-Latina Black; and non-Latina White-creating 4 models for analysis: unadjusted (Model 1) and adjusted for sociodemographic factors (Model 2), sociodemographic plus medical risk factors (Model 3), and Model 3 factors plus smoking (Model 4). Results Infant LBW rate for Black Latinas (7.9%) was higher than White Latinas (5.6%) and varied by nativity: US-born (8.9%) versus foreign-born (6.1%). Among all study groups, US-born Black Latinas' LBW rate (8.9%) was second only to non-Latina Blacks (11.0%). In unadjusted Model 1, US-born Black Latinas had 81% (odds ratio [OR]: 1.81; 95% confidence interval [CI]: 1.74-1.88) and foreign-born Black Latinas had 22% (OR: 1.22; 95% CI 1.15-1.29) higher odds of LBW than non-Latina White women (reference group). However, in Model 2, ORs for foreign-born Black Latinas were nearly identical to non-Latina Whites (OR: 1.03; 95% CI 0.97-1.1), while US-born Black Latinas' odds were still 47% higher (OR: 1.47; 95% CI 1.42-1.53). Model 3 ORs for each group were similar to Model 2. Conclusions for Practice A significant subgroup of Latina women self-identify as Black, and their LBW rates are higher than White Latinas. Black Latinas born in the United States fare worse than their foreign-born counterparts, implicating negative effects of Black race specific to the US context.

Mental Health and Substance Use-Related Hospitalizations Among Women of Reproductive Age in Illinois and Wisconsin.

INTRODUCTION: Mental health and substance use are growing public health concerns, but established surveillance methods do not measure the burden of these conditions among women of reproductive age. We developed a standardized indicator from administrative data to identify inpatient hospitalizations related to mental health or substance use (MHSU) among women of reproductive age, as well as co-occurrence of mental health and substance use conditions among those hospitalizations. MATERIALS AND METHODS: We used inpatient hospital discharge data from 2012-2014 for women aged 15-44 residing in Illinois and Wisconsin. We identified MHSU-related hospitalizations through the principal International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnosis and first-listed ICD-9-CM external cause of injury code (E code). We classified hospitalizations as related to 1 of 3 mutually exclusive categories: a mental disorder, a substance use disorder, or an acute MHSU-related event. We defined co-occurrence as the presence of both mental health and substance use codes in any available diagnosis or E-code field. RESULTS: Of 1 173 758 hospitalizations of women of reproductive age, 150 318 (12.8%) were related to a mental disorder, a substance use disorder, or an acute MHSU-related event, for a rate of 135.6 hospitalizations per 10 000 women. Of MHSU-related hospitalizations, 115 163 (76.6%) were for a principal mental disorder, 22 466 (14.9%) were for a principal substance use disorder, and 12 709 (8.5%) were for an acute MHSU-related event; 42.4% had co-occurring mental health codes and substance use codes on the discharge record. PRACTICE IMPLICATIONS: MHSU-related disorders and events are common causes of hospitalization for women of reproductive age, and nearly half of these hospitalizations involved co-occurring mental health and substance use diagnoses or events. This new indicator may improve public health surveillance by establishing a systematic and comprehensive method to measure the burden of MHSU-related hospitalizations among women of reproductive age.

State-Identified Implementation Strategies to Increase Uptake of Immediate Postpartum Long-Acting Reversible Contraception Policies.

BACKGROUND: In 2014, the Association of State and Territorial Health Officials (ASTHO) convened a multistate Immediate Postpartum Long-Acting Reversible Contraception (LARC) Learning Community to facilitate cross-state collaboration in implementation of policies. The Learning Community model was based on systems change, through multistate peer-to-peer learning and strategy-sharing activities. This study uses interview data from 13 participating state teams to identify state-implemented strategies within defined domains that support policy implementation. MATERIALS AND METHODS: Semistructured interviews were conducted by the ASTHO team with state team members participating in the Learning Community. Interviews were transcribed and implementation strategies were coded. Using qualitative analysis, the state-reported domains with the most strategies were identified. RESULTS: The five leading domains included the following: stakeholder partnerships; provider training; outreach; payment streams/reimbursement; and data, monitoring and evaluation. Stakeholder partnership was identified as a cross-cutting domain. Every state team used strategies for stakeholder partnerships and provider training, 12 reported planning or engaging in outreach efforts, 11 addressed provider and facility reimbursement, and 10 implemented data evaluation strategies. All states leveraged partnerships to support information sharing, identify provider champions, and pilot immediate postpartum LARC programs in select delivery facilities. CONCLUSIONS: Implementing immediate postpartum LARC policies in states involves leveraging partnerships to develop and implement strategies. Identifying champions, piloting programs, and collecting facility-level evaluation data are scalable activities that may strengthen state efforts to improve access to immediate postpartum LARC, a public health service for preventing short interbirth intervals and unintended pregnancy among postpartum women.

The age-related patterns of preterm birth among urban African-American and non-Latina White mothers: The effect of paternal involvement.

Few studies have examined contributions of paternal factors to birth outcomes. Weathering is a pattern of increasing rates of adverse birth outcome with increasing maternal age. This study evaluates for an association between paternal involvement and weathering in the context of preterm birth (PTB, <37 weeks) among non-Hispanic African-American and non-Hispanic White women with and without lifelong exposure to neighborhood poverty. Using the Illinois transgenerational dataset with appended US census income information of infants (1989-1991) and their mothers (1956-1976), we compared infants of women by degree of paternal involvement: married, unmarried with father named on birth certificate, and unnamed father. Data were stratified by maternal residence in higher or lower income neighborhoods at both the time of mothers' birth and infants' birth, estimating maternal lifelong economic context. We computed race-specific PTB rates according to maternal age, lifelong neighborhood income, and paternal involvement. We calculated Mantel-Haenszel chi-square tests of linear trend from contingency tables to evaluate weathering. Among African-Americans (n = 39,991) with unnamed fathers and lifelong residence in lower income neighborhoods, PTB rate was lowest among teens at 18.8%, compared to 21.5% for 30-35 year-old mothers (p for linear trend <0.05). Among African-Americans with unnamed fathers and lifelong residence in higher income neighborhoods, PTB rate among teens was 16%, compared to 25% for 30-35 year-old mothers (p = 0.21). Among married African-Americans with lifelong residence in lower income neighborhoods, PTB rate among teens was 16.4%, compared to 12.5% for 30-35 year-old mothers (p = 0.79). Among married African-Americans with lifelong residence in higher income neighborhoods, PTB rate among teens was 20%, compared to 11.4% for 30-35 year-old mothers (p = 0.40). White mothers (n = 31,981) did not demonstrate weathering, regardless of paternal involvement and neighborhood poverty. We conclude that weathering was not seen among married African-Americans, independent of neighborhood income, suggesting a potentially protective mechanism associated with paternal involvement.

Acceptability of Postpartum Contraception Counseling at the Well Baby Visit.

Objectives The postpartum period is a high-risk time for unintended pregnancy, and additional opportunities to provide contraception are needed. Our objective was to evaluate the acceptability of providing postpartum contraceptive counseling at a pediatric well baby visit, and compare it to counseling at the routine postpartum visit. Methods Postpartum women (100 per group) were recruited for this cohort study at pediatric well baby visits and obstetric postpartum visits at an academic medical center. Well baby participants completed a baseline survey followed by contraceptive counseling by an obstetrician or midwife and a post-counseling survey. Postpartum participants were surveyed after their visit only. Results All well baby visit participants completed the intervention and were enrolled earlier in the postpartum period than postpartum visit participants (mean = 4.1 vs. 6.6 weeks, respectively, p < 0.01). Following counseling, 95% of well baby participants reported being very comfortable discussing contraception, compared to 83% before counseling (RR 1.14, 95% CI 1.06, 1.25) and a higher proportion reported being very likely to use a contraception prescription obtained at the well baby visit (79% after counseling vs. 65% before; RR 1.23, 95% CI 1.08, 1.39). Similar proportions of postpartum and well baby participants were very comfortable discussing contraception at their visits (91 vs. 95%, respectively). Conclusions for practice Contraceptive counseling paired with well baby visits is acceptable among postpartum women. Acceptability increased further after the counseling intervention at the well baby visit. Obstetricians and Pediatricians can partner to offer contraceptive counseling at the well baby visit to increase opportunities for contraception education at an earlier time postpartum.

Affluent-Born White Mother's Descending Neighborhood Income and Infant Mortality: A Population-Based Study.

Objectives To determine whether affluent-born White mother's descending neighborhood income is associated with infant mortality rates (< 365 day, IMR). Methods Stratified and multilevel logistic regression analyses were completed on the Illinois transgenerational dataset of singleton births (1989-1991) to non-Latina White mothers (1956-1976) with an early-life residence in affluent neighborhoods (defined as the fourth quartile of income distribution). The breadth of descending neighborhood income was defined by mother's neighborhood income at the time of delivery. Results Infants of White mothers (n = 4890) who did not suffer descending neighborhood income by the time of delivery had a first-year mortality rate of 5.1/1,000. Infants of White mothers who experienced minor (n = 5112), modest (n = 2158), or extreme (n = 339) descending neighborhood income had IMR of 6.5/1,000, 14.4/1,000, and 11.8/1,000, respectively; RR [95% CI] = 1.3 [0.8, 2.1], 2.8 [1.7, 4.8], and 2.3 [0.8, 6.6], respectively. The incidence of young maternal age, inadequate prenatal care utilization, and cigarette smoking rose as descending neighborhood income increased, p < 0.01. In multilevel logistic regression models, the adjusted (controlling for selected individual-level co-variates) OR [95% CI] of infant mortality for White women with an early-life residence in affluent neighborhoods who subsequently experienced minor or modest to extreme (versus absent) descending neighborhood income equaled 1.0 [0.6, 1.8] and 2.1 [1.1, 3.8] respectively. Conclusions White mother's modest to extreme descending neighborhood income from early-life residence in affluent neighborhoods is associated with a twofold greater risk of infant mortality independent of selected biologic, medical, and behavioral characteristics.

Relationship between mother-infant mutual dyadic responsiveness and premature infant development as measured by the Bayley III at 6 weeks corrected age.

BACKGROUND: The quality of mother-preterm infant interaction has been identified as a key factor in influencing the infant's later development and language acquisition. The relationship between mother-infant responsiveness and later development may be evident early in infancy, a time period which has been understudied. AIM: Describe the relationship between mother-infant mutual dyadic responsiveness and premature infant development. DESIGN: This study employed a secondary analysis of data from the 6-week corrected age (CA) follow-up visit of the Hospital-Home Transition: Optimizing Prematures' Environment (H-HOPE) study, a randomized clinical trial testing the efficacy of a mother- and infant- focused intervention for improving outcomes among premature infants. SUBJECTS: Premature infants born between 29 and 34 weeks gestational age and their mothers who had social-environmental risks. OUTCOME MEASURES: At 6-weeks corrected age, a play session was coded for the quality of mutual responsiveness (Dyadic Mutuality Code). Development was assessed via the Bayley Scales of Infant and Toddler Development, 3rd edition. RESULTS: Of 137 mother-infant dyads, high, medium and low mutual responsiveness was observed for 35.8%, 34.3% and 29.9%, respectively. Overall motor, language and cognitive scores were 115.8 (SD = 8.2), 108.0 (7.7) and 109.3 (7.9). Multivariable linear models showed infants in dyads with high versus low mutual responsiveness had higher scores on the motor (ß = 3.07, p = 0.06) and language (ß = 4.47, p = 0.006) scales. CONCLUSION: High mutual responsiveness in mother-premature infant dyads is associated with significantly better language development and marginally better motor development.

Policy change is not enough: engaging provider champions on immediate postpartum contraception.

Rates of short-interval pregnancies that result in unintended pregnancies remain high in the United States and contribute to adverse reproductive health outcomes. Long-acting reversible contraception methods have annual failure rates of <1%, compared with 9% for oral contraceptive pills, and are an effective strategy to reduce unintended pregnancies. To increase access to long-acting reversible contraception in the immediate postpartum period, several State Medicaid programs, which include those in Iowa and Louisiana, recently established reimbursement policies to remove the barriers to reimbursement of immediate postpartum long-acting reversible contraception insertion. We used a mixed-methods approach to analyze 2013-2015 linked Medicaid and vital records data from both Iowa and Louisiana and to describe trends in immediate postpartum long-acting reversible contraception provision 1 year before and after the Medicaid reimbursement policy change. We also used data from key informant interviews with state program staff to understand how provider champions affected policy uptake. We found that the monthly average for the number of insertions in Iowa increased from 4.6 per month before the policy to 6.6 per month after the policy; in Louisiana, the average number of insertions increased from 2.6 per month before the policy to 45.2 per month. In both states, the majority of insertions occurred at 1 academic/teaching hospital. In Louisiana, the additional increase may be due to the engagement of a provider champion who worked at both the state and facility level. Recruiting, training, engaging, and supporting provider champions, as facilitators, with influence at state and facility levels, is an important component of a multipart strategy for increasing successful implementation of state-level Medicaid payment reform policies that allow reimbursement for immediate postpartum long-acting reversible contraception insertions.

Deconstructing a disparity: explaining excess preterm birth among U.S.-born black women.

PURPOSE: To determine components of excess preterm birth (PTB) rates for U.S.-born black women relative to both foreign-born black women and U.S.-born white women attributable to differences in observed sociodemographic, behavioral, and medical risk factors. METHODS: Using the 2013 U.S. natality files, we used Oaxaca-Blinder decomposition on the absolute scale to estimate the contribution of the group differences in the prevalence of PTB predictors between U.S.- and foreign-born black women and U.S.-born black and U.S.-born white women. RESULTS: U.S.-born blacks had a 3.2 (95% confidence interval: 3.0-3.5) and 4.4 (95% confidence interval: 4.3-4.5) percentage point higher risk of PTB than foreign-born blacks and U.S.-born whites, respectively. The variables in the models explained between 18% and 27% of the PTB disparities. Differences in paternal acknowledgment (about 12%), maternal hypertension (about 7%-11%), and maternal education (about 6%-10%) explained the largest proportion of these disparities. CONCLUSIONS: Programs and policies that address both distal and proximate factors, including the social determinants of health and the prevention and management of hypertension, may reduce the higher rates of PTB among U.S.-born black women compared to foreign-born black women and U.S.-born white women.

Using a multi-state Learning Community as an implementation strategy for immediate postpartum long-acting reversible contraception.

BACKGROUND: Implementation strategies are imperative for the successful adoption and sustainability of complex evidence-based public health practices. Creating a learning collaborative is one strategy that was part of a recently published compilation of implementation strategy terms and definitions. In partnership with the Centers for Disease Control and Prevention and other partner agencies, the Association of State and Territorial Health Officials recently convened a multi-state Learning Community to support cross-state collaboration and provide technical assistance for improving state capacity to increase access to long-acting reversible contraception (LARC) in the immediate postpartum period, an evidence-based practice with the potential for reducing unintended pregnancy and improving maternal and child health outcomes. During 2015-2016, the Learning Community included multi-disciplinary, multi-agency teams of state health officials, payers, clinicians, and health department staff from 13 states. This qualitative study was conducted to better understand the successes, challenges, and strategies that the 13 US states in the Learning Community used for increasing access to immediate postpartum LARC. METHODS: We conducted telephone interviews with each team in the Learning Community. Interviews were semi-structured and organized by the eight domains of the Learning Community. We coded transcribed interviews for facilitators, barriers, and implementation strategies, using a recent compilation of expert-defined implementation strategies as a foundation for coding the latter. RESULTS: Data analysis showed three ways that the activities of the Learning Community helped in policy implementation work: structure and accountability, validity, and preparing for potential challenges and opportunities. Further, the qualitative data demonstrated that the Learning Community integrated six other implementation strategies from the literature: organize clinician implementation team meetings, conduct educational meetings, facilitation, promote network weaving, provide ongoing consultation, and distribute educational materials. CONCLUSIONS: Convening a multi-state learning collaborative is a promising approach for facilitating the implementation of new reimbursement policies for evidence-based practices complicated by systems challenges. By integrating several implementation strategies, the Learning Community serves as a meta-strategy for supporting implementation.

Early Preterm Birth Across Generations Among Whites and African-Americans: A Population-Based Study.

Objectives To determine the extent to which non-Latina White and African-American mother's gestational age is associated with extremely early (<30 weeks), modestly early (30-33 weeks), and late (34-36 weeks) infant preterm birth (PTB) rates. Methods Race-specific stratified and multivariable logistic regression analyses were performed on the Illinois Transgenerational Birth File of non-Latino White and African-American infants (born 1989-1991) and their mothers (born 1956-1976). Results White mothers (n = 184) born at <30 weeks had a greater extremely early infant PTB rate than White mothers (n = 131,980) born at term: 1.6 versus 0.5%, respectively; RR = 3.6 (1.2, 11.0). African-American mothers (n = 269) born at <30 weeks had a greater extremely early infant PTB rate than African-American mothers (n = 34,885) born at term: 4.1 versus 2.1%, respectively; RR = 2.0 (1.1, 3.6). In logistic regression models the adjusted (controlling for maternal age, education, parity, prenatal care, marital status, and cigarette smoking) OR of extremely early PTB for White and African-American mothers born <30 (compared to ≥37) weeks equaled 4.0 (1.2, 12.6) and 2.3 (1.2, 4.3), respectively. The adjusted OR of modestly early PTB for White and African-American mothers born 30-33 (compared to ≥37) weeks equaled 1.6 (1.0, 2.5) and 1.3 (0.9, 1.7), respectively. The adjusted OR of late PTB for White and African-American mothers born 34-36 (compared to ≥37) weeks equaled 1.2 (1.0, 1.3) and 1.1 (1.0, 1.2), respectively. Conclusions A generational association of extremely early, but not modestly early or late, PTB exists among non-Latino Whites and African-Americans.

Maternal weight status and responsiveness to preterm infant behavioral cues during feeding.

BACKGROUND: Parental obesity is highly predictive of child obesity, and preterm infants are at greater risk of obesity, but little is known about obese and non-obese mothers' responsiveness to preterm infant cues during feeding. The relationship between maternal weight status and response to preterm infant behavioral cues during feeding at 6-weeks corrected age was examined. METHODS: This secondary analysis used data from a randomized clinical trial. Maternal weight was coded during a play session. Mother-infant interaction during feeding was coded using the Nursing Child Assessment Satellite Training Feeding Scale (NCAST). We used multivariate linear regressions to examine NCAST scores and multivariate logistic regressions for the two individual items, satiation cues and termination of feeding. RESULTS: Of the 139 mothers, 56 (40.3%) were obese, two underweight women were excluded. Obese mothers did not differ from overweight/normal weight mothers for overall NCAST scores, but they had higher scores on response to infant's distress subscale (mean = 10.2 vs. 9.6, p = 0.01). The proportion of infants who exhibited satiation cues did not differ by maternal weight. Obese mothers were more likely than overweight/normal weight mothers to terminate the feeding when the infant showed satiation cues (82.1% vs. 66.3%, p = 0.04, adjusted OR = 2.31, 95% CI = 0.97, 5.48). CONCLUSIONS: Limitations include lack of BMI measures and small sample size. Additional research is needed about maternal weight status and whether it influences responsiveness to preterm infant satiation cues. Results highlight the need for educating all mothers of preterm infants regarding preterm infant cues. TRIAL REGISTRATION: NCT02041923 .

The Relation of Maternal Birth Weight to African-American and Non-Latina White Twin Pregnancy Outcomes: A Population-Based Study.

Objectives The authors investigated the association between maternal birth weight and adverse birth outcome as measured by rates of low birth weight (<2500 g, LBW), preterm birth (<37 weeks, PTB), and small for gestational age (weight <10th percentile for gestational age, SGA) among African American and White twin pregnancies. Methods Stratified and multivariable regression analyses were performed on the Illinois transgenerational dataset of non-Latina African American and non-Latina White twin pairs (born 1989-1991) and their mothers (born 1956-1976). Results Former LBW (n = 104) and non-LBW (n = 742) African American mothers had LBW rates in both twins of 76 and 56 %, respectively; RR (95 % CI) = 1.4 (1.2-1.6). Former LBW (n = 105) and non-LBW (n = 2136) White mothers had LBW rates in both twins of 41 and 34 %, respectively; RR = 1.2 (0.9-1.5). In multivariable regression models, the adjusted (controlling for maternal age, education, marital status, parity, prenatal care usage, and cigarette smoking) RR of LBW in both twins among former LBW (compared to non-LBW) African American and White mothers equaled 1.4 (1.2-1.6) and 1.2 (0.9-1.5), respectively. Maternal LBW was associated with a modestly increased risk of PTB but not SGA among African American twin pregnancies: adjusted RR = 1.3 (1.1-1.4) and 1.1 (0.8-1.5), respectively. Conclusions In African American twin pregnancies, maternal LBW is a risk factor for LBW in both twins. Further research is needed to determine whether a similar generational association occurs among non-Latina White twin pregnancies.
