Analysis of State-Level Immigrant Policies and Preterm Births by Race/Ethnicity Among Women Born in the US and Women Born Outside the US.

ABSTRACT:

Importance

Criminalizing immigrant policies, a form of structural racism, are associated with preterm birth; however, to date, few population studies have examined this association by race and nativity status or examined the association of inclusive immigrant policies with preterm birth.

Objective

To assess the extent to which variation in preterm birth by race/ethnicity and nativity status is associated with state-level criminalizing vs inclusive immigrant policies.

Design, setting, and participants

This retrospective, cross-sectional study analyzed birth record data from all 50 states and the District of Columbia in 2018, as well as state-level indicators of inclusive and criminalizing immigrant policies. White, Black, Asian, and Latina women who had singleton births were included in the study. Statistical analysis was performed from June 1, 2020, to February 5, 2021. Two continuous variables were created to capture the number of criminalizing vs inclusive immigrant policies in effect as of 2017 in each state.

Main outcomes and measures

The main outcome measure was preterm birth (<37 weeks' gestation).

Results

Among the 3 455 514 live births that occurred in 2018, 10.0% were preterm, and 23.2% were to mothers born outside the US. Overall, for women born outside the US, each additional state-level inclusive policy was associated with a 2% decrease in preterm birth (adjusted odds ratio [aOR], 0.98 [95% CI, 0.96-1.00]); there were no significant associations between inclusive policies and preterm birth among women born in the US. In models examining the combined associations of criminalizing and inclusive immigrant policies with preterm birth, each additional criminalizing policy was associated with a 5% increase in preterm birth among Black women born outside the US (aOR, 1.05 [95% CI, 1.00-1.10]). Each additional inclusive immigrant policy was associated with a lower likelihood of preterm birth for Asian women born in the US (aOR, 0.95 [95% CI, 0.93-0.98]) and White women born outside the US (aOR, 0.97 [95% CI, 0.95-0.99]). No significant associations were found among other groups.

Conclusions and relevance

This study suggests that criminalizing immigrant policies are associated with an increase in preterm birth specifically for Black women born outside the US. Inclusive immigrant policies are associated with a decrease in preterm birth for immigrants overall, Asian women born in the US, and White women born outside the US. No associations were found between criminalizing or inclusive immigrant policies and preterm birth among Latina women.

Project description:Importance:Severe morbidity in very preterm infants is associated with profound clinical implications on development and life-course health. However, studies of racial/ethnic disparities in severe neonatal morbidities are scant and suggest that these disparities are modest or null, which may be an underestimation resulting from the analytic approach used. Objective:To estimate racial/ethnic differences in severe morbidities among very preterm infants. Design, Setting, and Participants:This population-based retrospective cohort study was conducted in New York City, New York, using linked birth certificate, mortality data, and hospital discharge data from January 1, 2010, through December 31, 2014. Infants born before 24 weeks' gestation, with congenital anomalies, and with missing data were excluded. Racial/ethnic disparities in very preterm birth morbidities were estimated through 2 approaches, conventional analysis and fetuses-at-risk analysis. The conventional analysis used log-binomial regression to estimate the relative risk of 4 severe neonatal morbidities for the racial/ethnic groups. For the fetuses-at-risk analysis, Cox proportional hazards regression with death as competing risk was used to estimate subhazard ratios associating race/ethnicity with each outcome. Estimates were adjusted for sociodemographic factors and maternal morbidities. Data were analyzed from September 5, 2017, to May 21, 2018. Main Outcomes and Measures:Four morbidity outcomes were defined using International Classification of Diseases, Ninth Revision, diagnosis and procedure codes: necrotizing enterocolitis, intraventricular hemorrhage, bronchopulmonary dysplasia, and retinopathy of prematurity. Results:In total, 582 297 infants were included in this study. Of these infants, 285 006 were female (48.9%) and 297 291 were male (51.0%). Using the conventional approach in the very preterm birth subcohort, black compared with white infants had an increased risk of only bronchopulmonary dysplasia (adjusted risk ratio [aRR], 1.34; 95% CI, 1.09-1.64) and a borderline increased risk of necrotizing enterocolitis (aRR, 1.39; 95% CI, 1.00-1.93). Hispanic infants had a borderline increased risk of necrotizing enterocolitis (aRR, 1.39; 95% CI, 0.98-1.96), and Asian infants had an increased risk of retinopathy of prematurity (aRR, 1.85; 95% CI, 1.15-2.97). In the fetuses-at-risk analysis, black infants had a 4.40 times higher rate of necrotizing enterocolitis (95% CI, 2.98-6.51), a 2.73 times higher rate of intraventricular hemorrhage (95% CI, 1.63-4.57), a 4.43 times higher rate of bronchopulmonary dysplasia (95% CI, 2.88-6.81), and a 2.98 times higher rate of retinopathy of prematurity (95% CI, 2.01-4.40). Hispanic infants had an approximately 2 times higher rate for all outcomes, and Asian infants had increased risk only for retinopathy of prematurity (adjusted hazard ratio, 2.43; 95% CI, 1.43-4.11). Conclusions and Relevance:In this study, racial/ethnic disparities in neonatal morbidities among very preterm infants appear to be sizable, but may have been underestimated in previous studies, and may have implications for the future. Understanding these racial/ethnic disparities is important, as they may contribute to inequalities in health and development later in the child's life.

Project description:ImportanceThe association of state-level immigrant policies with uninsurance among Latino youths remains unknown.ObjectiveTo assess the association of state-level immigrant integration and criminalization policies with health insurance coverage among US-born Latino youths by maternal citizenship.Design, setting, and participantsThis cross-sectional study analyzed secondary data from the American Community Survey, January 1, 2016, to December 31, 2018, for US-born Latino youths (age, ≤17 years) and their mothers (age, 18-64 years) as well as state-level indicators of immigrant integration and criminalization policies (in all 50 states and the District of Columbia).ExposuresImmigrant integration and criminalization policies.Main outcomes and measuresThe main outcome was maternal reports of youth uninsurance status at the time of the American Community Survey interview. Variation in youth uninsurance by maternal citizenship, state immigrant integration policy context, and state immigrant criminalization policy context were examined. All analyses were conducted with weighted survey data.ResultsOf the 226 691 US-born Latino youths (115 431 [50.92%] male; mean [SD] age, 7.66 [4.92] years) included in the study, 36.64% (95% CI, 36.21%-36.92%) had noncitizen mothers. Overall, 7.09% (95% CI, 6.78%-7.41%) of noncitizen mothers reported that their youths were uninsured compared with 4.68% (95% CI, 4.49%-4.88%) of citizen mothers. Of uninsured youths who resided in states with a low level of immigrant integration policies, 9.10% (8.22%-10.06%) had noncitizen mothers and 4.75% (95% CI, 4.19%-5.37%) had citizen mothers; of uninsured youths who resided in states with high criminalization policies, 9.37% (95% CI, 8.90%-9.87%) had noncitizen mothers and 5.91% (95% CI, 5.64%-6.20%) had citizen mothers. In states with few immigrant integration policies, the probability of uninsurance among youths with noncitizen mothers was 3.3% (95% CI, 2.3%-4.4%) higher than that among youths with citizen mothers. Among youths with noncitizen mothers, the difference in the probability of uninsurance between those residing in states with a low level vs a high level of immigrant integration policies was 2.1% (95% CI, 0.6%-3.6%). Among youths residing in states with high levels of immigrant criminalization policies, those with noncitizen mothers had a 2.6% (95% CI, 1.9%-3.0%) higher probability of being uninsured compared with those whose mothers were citizens. Among youths with noncitizen mothers, the difference in the probability of uninsurance between those who resided in a state with a low level vs a state with a high level of immigrant criminalization policies was 1.7% (95% CI, 0.7%-2.7%).Conclusions and relevanceThe findings of this cross-sectional study suggest that among US-born Latino youths, disparities in uninsurance by maternal citizenship are associated with state-level immigrant integration and criminalization policies and that anti-immigrant policies may be associated with disparities in health care access for US-born Latino youths.

Project description:Importance:Large racial/ethnic disparities in breastfeeding are associated with adverse health outcomes. Objectives:To examine breastfeeding trends by race/ethnicity from 2009 to 2015 and changes in breastfeeding gaps comparing racial/ethnic subgroups with white infants from 2009-2010 to 2014-2015. Design, Setting, and Participants:This study used data from 167?842 infants from the National Immunization Survey-Child (NIS-Child), a random-digit-dialed telephone survey among a complex, stratified, multistage probability sample of US households with children aged 19 to 35 months at the time of the survey. This study analyzed data collected from January 1, 2011, through December 31, 2017, for children born between 2009 and 2015. Exposures:Child's race/ethnicity categorized as Hispanic or non-Hispanic white, black, Asian, or American Indian or Alaskan Native. Main Outcomes and Measures:Breastfeeding rates, including ever breastfeeding, exclusive breastfeeding through 6 months, and continuation of breastfeeding at 12 months. Results:This study included 167?842 infants (mean [SD] age, 2.33 [0.45] years; 86?321 [51.4%] male and 81?521 [48.6%] female). Overall unadjusted breastfeeding rates increased from 2009 to 2015 by 7.1 percentage points for initiation, 9.2 percentage points for exclusivity, and 11.3 percentage points for duration, with considerable variation by race/ethnicity. Most racial/ethnic groups had significant increases in breastfeeding rates. From 2009-2010 to 2014-2015, disparities in adjusted breastfeeding rates became larger between black and white infants. For example, the difference for exclusive breastfeeding through 6 months between black and white infants widened from 0.5 to 4.5 percentage points with a 4.0% difference in difference (P?<?.001) from 2009-2010 to 2014-2015. In contrast, the breastfeeding differences between Hispanic, Asian, and American Indian or Alaskan Native infants and white infants became smaller or stayed the same except for continued breastfeeding at 12 months among Asians. For example, the difference in continued breastfeeding at 12 months between Hispanic and white infants decreased from 7.8 to 3.8 percentage points between 2 periods, yielding a -4.0% difference in difference (P?<?.001). Because of positive trends among all race/ethnicities, these reduced differences were likely associated with greater increases among white infants throughout the study years. Conclusions and Relevance:Despite breastfeeding improvements among each race/ethnicity group, breastfeeding disparities between black and white infants became larger when breastfeeding improvements decreased even further among black infants in 2014-2015. The reduced breastfeeding gaps among all other nonwhite groups may be associated with greater increases among white infants. More efforts appear to be needed to improve breastfeeding rates among black infants.
