Understanding how the concentration of neighborhood advantage and disadvantage affects spina bifida risk among births to non-Hispanic white and Hispanic women, Texas, 1999-2014

Having more resilience factors only gets you so far in the context of neighborhood disadvantage: understanding differential predictors of internalizing symptoms and body mass index in youth with spina bifida

OBJECTIVE

The primary aim of this study was to determine if neighborhood disadvantage predicted internalizing symptoms and body mass index (BMI) in youth with spina bifida (SB), while accounting for several sociodemographic factors. We also explored whether resilience factors helped explain associations between neighborhood disadvantage and internalizing symptoms or neighborhood disadvantage and BMI.

METHODS

Participants (n = 69, Mage=14.13, Range: 8-20, 51% biological female, 25% Hispanic/Latinx White, 28% Other/Multiracial, 48% non-Hispanic/Latinx White) were drawn from a retrospective chart review of clinical data, including self-reported resilience factors and internalizing symptoms, collected as part of the standard of care in a multidisciplinary pediatric SB clinic. Neighborhood disadvantage scores were extracted from participant addresses. Using structural equation modeling, we examined whether neighborhood disadvantage predicted BMI and internalizing symptoms. We explored whether these paths were mediated by resilience factors.

RESULTS

Higher neighborhood disadvantage predicted higher BMI and lower internalizing symptoms. Higher neighborhood disadvantage predicted higher resilience factors, which predicted lower internalizing symptoms. Higher resilience factors did not predict BMI.

CONCLUSIONS

Neighborhood disadvantage may require youth with SB to navigate their way to additional resilience factors to maintain better psychosocial outcomes. However, having more resilience factors may not help offset the physical health costs of disadvantaged neighborhoods.

Characteristics and Outcomes of Patients With Spina Bifida in Texas by Patient Age

INTRODUCTION

Spina bifida (SB) occurs in 3.5/10,000 live births and is associated with significant long-term neurologic and urologic morbidity. We explored the characteristics and outcomes of pediatric patients with SB and the facilities that treat them in Texas.

METHODS

We retrospectively reviewed a statewide hospital inpatient discharge database (2013-2021) to identify patients aged <18 y with SB using International Classification of Diseases 9/10 codes. Patients transferred to outside hospitals were excluded to avoid double-counting. Descriptive statistics and chi-square test were performed.

RESULTS

Seven thousand five hundred thirty one inpatient hospitalizations with SB were analyzed. Most SB care is provided by a few facilities. Two facilities (1%) averaged >100 SB admissions per year (33% of patients), while 15 facilities (8%) treat 10-100 patients per year (51% of patients). Most facilities (145/193, 75%) average less than one patient per year. Infants tended to be sicker (17% extreme illness severity, P < 0.001). Overall mortality is low (1%), primarily occurring in the neonatal period (8%, P < 0.001). Most admissions are associated with surgical intervention, with 63% of encounters having operating room charges with an average cost of $25,786 ± 24,884. Admissions for spinal procedures were more common among infants, whereas admissions for genitourinary procedures were more common among older patients (P < 0.001). The average length of stay was 8 ± 16 d with infants having the longest length of stay (19 ± 33, P < 0.001).

CONCLUSIONS

Patients have significant long-term health needs with evolving pediatric surgical indications as they grow. Pediatric SB care is primarily provided by a small number of facilities in Texas. Longitudinal care coordination of their multidisciplinary surgical care is needed to optimize patient care.

Predictors of medical adherence following a bowel management program for youth and young adults with Spina Bifida

PURPOSE

To evaluate individual and community sociodemographic factors that predict bowel regimen adherence in youth and young adults with Spina Bifida (SB) following participation in a bowel management program (BMP).

METHODS

Participants were drawn from clinical cases seen through an International Center for Colorectal and Urogenital Care. Area deprivation index (ADI) scores were extracted from participant addresses and bowel regimen adherence data were collected from the electronic medical record (EMR).

RESULTS

Participants' mean age was 8.06 years old, 51.7% were male, 72.4% white, 37.9% Hispanic, 56.9% government insurance, 89.7% myelomeningocele, 15.5% non-adherent. Average neighborhood disadvantage was 5.19 (SD:2.83, range:1-10). After controlling for variables correlated with adherence (p < .20), every one decile higher neighborhood disadvantage score was associated with a 48% decrease in the odds of being adherent (OR = 0.52, p = .005, 95% CI: - 101.90, - 0.21).

CONCLUSION

Our results suggest that neighborhood disadvantage is a strong predictor of medical adherence following a BMP, more so than other sociodemographic and health-related variables. These results may assist with identifying which individuals may be at higher risk for poor health outcomes due to neighborhood socioeconomic disadvantage and help health care systems intervene proactively.

Folic Acid and the Prevention of Birth Defects: 30 Years of Opportunity and Controversies

For three decades, the US Public Health Service has recommended that all persons capable of becoming pregnant consume 400 μg/day of folic acid (FA) to prevent neural tube defects (NTDs). The neural tube forms by 28 days after conception. Fortification can be an effective NTD prevention strategy in populations with limited access to folic acid foods and/or supplements. This review describes the status of mandatory FA fortification among countries that fortify (n = 71) and the research describing the impact of those programs on NTD rates (up to 78% reduction), blood folate concentrations [red blood cell folate concentrations increased ∼1.47-fold (95% CI, 1.27, 1.70) following fortification], and other health outcomes. Across settings, high-quality studies such as those with randomized exposures (e.g., randomized controlled trials, Mendelian randomization studies) are needed to elucidate interactions of FA with vitamin B12 as well as expanded biomarker testing.

The Index of Concentration at the Extremes (ICE) and Pregnancy-Associated Mortality in Louisiana, 2016-2017

OBJECTIVES

Social and contextual factors underlying the continually disproportionate and burdensome risk of adverse health outcomes experienced by Black women in the US are underexplored in the literature. The aim of this study was to use an index based on area-level population distributions of race and income to predict risk of death during pregnancy and up to 1 year postpartum among women in Louisiana.

METHODS

Using vital records data provided by the Louisiana Department of Health 2016-2017 (n = 125,537), a modified Poisson model was fit with generalized estimating equations to examine the risk of pregnancy-associated death associated with census tract-level values of the Index of Concentration at the Extremes (ICE)-grouped by tertile-while adjusting for both individual and tract-level confounders.

RESULTS

Analyses resulted in an estimated 1.73 (95% CI 1.02-2.93) times increased risk for pregnancy-associated death for those in areas which were characterized by concentrated deprivation (high proportions of Black and low-income residents) relative to those in areas of concentrated privilege (high proportions of white and high-income residents), independent of other factors.

CONCLUSIONS FOR PRACTICE

In addition to continuing to consider the deeply entrenched racism and economic inequality that shape the experience of pregnancy-associated death, we must also consider their synergistic effect on access to resources, maternal population health, and health inequities.

Racialized economic segregation and health outcomes: A systematic review of studies that use the Index of Concentration at the Extremes for race, income, and their interaction

Extensive research shows that residential segregation has severe health consequences for racial and ethnic minorities. Most research to date has operationalized segregation in terms of either poverty or race/ethnicity rather than a synergy of these factors. A novel version of the Index of Concentration at the Extremes (ICERace-Income) specifically assesses racialized economic segregation in terms of spatial concentrations of racial and economic privilege (e.g., wealthy white people) versus disadvantage (e.g., poor Black people) within a given area. This multidimensional measure advances a more comprehensive understanding of residential segregation and its consequences for racial and ethnic minorities. The aim of this paper is to critically review the evidence on the association between ICERace-Income and health outcomes. We implemented the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to conduct a rigorous search of academic databases for papers linking ICERace-Income with health. Twenty articles were included in the review. Studies focused on the association of ICERace-Income with adverse birth outcomes, cancer, premature and all-cause mortality, and communicable diseases. Most of the evidence indicates a strong association between ICERace-Income and each health outcome, underscoring income as a key mechanism by which segregation produces health inequality along racial and ethnic lines. Two of the reviewed studies examined racial disparities in comorbidities and health care access as potential explanatory factors underlying this relationship. We discuss our findings in the context of the extant literature on segregation and health and propose new directions for future research and applications of the ICERace-Income measure.

The prevalence of birth defects among non-Hispanic Asian/Pacific Islanders and American Indians/Alaska Natives in Texas, 1999-2015

BACKGROUND

There is considerable variability in the prevalence of birth defects among racial/ethnic groups. This study estimated birth defect prevalence among the less studied non-Hispanic (NH) Asian/Pacific Islander (PI) and American Indian/Alaska Native (AI/AN) populations in Texas relative to NH Whites.

METHODS

Data were obtained from the Texas Birth Defect Registry from 1999 to 2015 for deliveries to Texas-resident women who were NH White, NH Asian/PI, or AI/AN. This covers a live birth population of 2.6 million. Prevalence ratios and 95% confidence intervals (95% CIs) were calculated for NH Asian/PIs and AI/ANs (relative to NH Whites) for 44 birth defects using Poisson regression adjusting for maternal age.

RESULTS

After adjustment there were 33 statistically significant prevalence ratios (aPRs). Among NH Asian/PIs, 23 defects had a lower aPR (0.38-0.86) and three defects had a higher aPR (1.19-2.50). AI/ANs had one defect with a significantly lower aPR (0.64) and six with a higher aPR (1.36-4.63).

CONCLUSIONS

Non-Hispanic Asian/PIs generally have a lower prevalence ratio for many birth defects while AI/ANs have a higher prevalence ratio compared to NH Whites. These findings update the limited literature on this topic and warrant additional research to identify the true associations across a range of birth defects among these understudied racial/ethnic groups.

Prevalence of selected birth defects by maternal nativity status, United States, 1999-2007

OBJECTIVES

We investigated differences in prevalence of major birth defects by maternal nativity within racial/ethnic groups for 27 major birth defects.

METHODS

Data from 11 population-based birth defects surveillance systems in the United States including almost 13 million live births (approximately a third of U.S. births) during 1999-2007 were pooled. We calculated prevalence estimates for each birth defect for five racial/ethnic groups. Using Poisson regression, crude and adjusted prevalence ratios (aPRs) were also calculated using births to US-born mothers as the referent group in each racial/ethnic group.

RESULTS

Approximately 20% of case mothers and 26% of all mothers were foreign-born. Elevated aPRs for infants with foreign-born mothers were found for spina bifida and trisomy 13, 18, and 21, while lower prevalence patterns were found for pyloric stenosis, gastroschisis, and hypospadias.

CONCLUSIONS

This study demonstrates that birth defects prevalence varies by nativity within race/ethnic groups, with elevated prevalence ratios for some specific conditions and lower prevalence for others. More detailed analyses focusing on a broader range of maternal behaviors and characteristics are required to fully understand the implications of our findings.
