Association of neighborhood-level social determinants and food environments with pediatric hypertension care

Fighting behavior, conflict perceptions, and firearm access among U.S. adolescents in a pediatric emergency department

OBJECTIVE

Prior evidence demonstrates that both firearm access and fighting can predict future violence and injury in adolescents. We aimed to examine associations between firearm access with fighting behavior and conflict perception in a sample of adolescents in an urban emergency department (ED) setting.

METHODS

In 2023, we conducted a secondary analysis of 13,610 adolescent encounters in the ED of a U.S. children's hospital from 2013 to 2020, using a universally applied, self-administered computerized behavioral health survey. We compared patient characteristics by reported firearm access and fighting behavior using chi-squared tests. Generalized estimating equations (GEE) were used to investigate associations between 1) fighting behavior and firearm access, and 2) between fighting behavior and respondent preference to and reporting of fighting incident to law enforcement after adjusting for race and ethnicity, age, and gender.

RESULTS

Approximately one-quarter of the sample reported past year fighting. Youth who reported fighting were more likely to report firearm access (AOR = 1.66, 95%CI = [1.49-1.86]). This association strengthened among youth who perceived continued conflict after a fight (AOR = 2.05, 95%CI = [1.73-2.43]). Youth who perceived continued conflict following a fight were more likely to report (AOR = 1.97, 95%CI = [1.65-2.36]) or want to report (AOR = 2.63, 95%CI = [1.81-3.81]) the fight to law enforcement.

CONCLUSIONS

Those perceiving continued conflict after a fight were more likely to report access to firearms and endorse retaliation; however, they were more likely to want to report the fight to law enforcement. These findings highlight the potential for more comprehensive ED risk assessment to reduce retaliation and reinjury for adolescents reporting fighting behavior.

Adolescent individual, school, and neighborhood influences on young adult diabetes risk

Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), this study examines the association between adolescent school and neighborhood contexts and the likelihood of diabetes in young adulthood. We apply cross-classified multi-level modeling (CCMM) techniques to examine the simultaneous influence of non-nested school and neighborhood contexts as well as individual, school, and neighborhood-level factors (N = 14,041 participants from 128 schools, 1933 neighborhoods). Our findings suggest that individual-level factors are most associated with young adult diabetes, with small contributions from school and neighborhood factors and a small proportion of the variation explained by school and neighborhood contexts.

Biomarkers, Socioeconomic Factors, and Right Ventricular Function After Surgical Repair for Tetralogy of Fallot

Right ventricular (RV) dysfunction early after tetralogy of Fallot (TOF) increases post-operative morbidity. We investigated associations of circulating biomarkers and socioeconomic factors with early post-operative RV systolic function. Single-center prospective cohort study of infants undergoing TOF repair. Six serologic biomarkers of myocardial fibrosis and wall stress collected at the time of surgery were measured with immunoassay. Geocoding was performed for socioeconomic factors. Multivariate adaptive regression splines (MARS) models identified factors associated with RV function parameters: fractional area change (FAC), global longitudinal strain and strain rate, and free wall strain and strain rate. Seventy-one patients aged 3.5 months (IQR 2.4, 5.2) were included. Galectin-3 was the highest ranked predictor for FAC, global longitudinal strain, and free wall strain, and procollagen type-I carboxy-terminal propeptide (PICP) was the highest ranked predictor for global longitudinal strain rate and free wall strain rate. Several neighborhood characteristics were also highly ranked. Models adjusted R² ranged from 0.71 to 0.85 (FAC, global longitudinal strain/strain rate), and 0.55-0.57 (RV free wall strain/strain rate). A combination of serologic biomarkers, socioeconomic, and clinical variables explain a significant proportion of the variability in RV function after TOF repair. These factors may inform pre-operative risk-stratification for these patients.

Investigating Racial and Socioeconomic Characteristics in Pediatric Sepsis Using Electronic Health Data

BACKGROUND AND OBJECTIVES

Racial/ethnic and socioeconomic disparities are reported in sepsis, with increased mortality for minority and low socioeconomic status groups; however, these studies rely on billing codes that are imprecise in identifying sepsis. Using a previously validated algorithm to detect pediatric sepsis using electronic clinical data, we hypothesized that racial/ethnic and socioeconomic status disparities would be evident in this group.

METHODS

We performed a retrospective study from a large, quaternary academic center, including sepsis episodes from January 20, 2011, to May 20, 2021, identified by an algorithm indicative of bacterial infection with organ dysfunction (cardiac, respiratory, renal, or hematologic). Multivariable logistic regression was used to measure association of race/ethnicity, insurance status, and social disorganization index, with the primary outcome of mortality, adjusting for age, sex, complex chronic conditions, organ dysfunction on day 1, source of admission, and time to hospital. Secondary outcomes were ICU admission, readmission, organ dysfunction-free days, and sepsis therapies.

RESULTS

Among 4532 patient episodes, the mortality rate was 9.7%. There was no difference in adjusted odds of mortality on the basis of race/ethnicity, insurance status, or social disorganization. There was no significant association between our predictors and ICU admission. Hispanic patients and publicly insured patients were more likely to be readmitted within 1 year (Hispanic odds ratio 1.28 [1.06-1.5]; public odds ratio 1.19 [1.05-1.35]).

CONCLUSIONS

Previously described disparities were not observed when using electronic clinical data to identify sepsis; however, data were only single center. There were significantly higher readmissions in patients who were publicly insured or identified as Hispanic or Latino, which require further investigation.

Adolescent individual, school, and neighborhood influences on young adult hypertension risk

BACKGROUND

Geographic and contextual socioeconomic risk factors in adolescence may be more strongly associated with young adult hypertension than individual-level risk factors. This study examines the association between individual, neighborhood, and school-level influences during adolescence on young adult blood pressure.

METHODS

Data were analyzed from the National Longitudinal Study of Adolescent to Adult Health (1994-1995 aged 11-18 and 2007-2008 aged 24-32). We categorized hypertension as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg. Secondary outcomes included continuous systolic and diastolic blood pressure. We fit a series of cross-classified multilevel models to estimate the associations between young adulthood hypertension with individual-level, school-level, and neighborhood-level factors during adolescence (i.e., fixed effects) and variance attributable to each level (i.e., random effects). Models were fit using Bayesian estimation procedures. For linear models, intra-class correlations (ICC) are reported for random effects.

RESULTS

The final sample included 13,911 participants in 128 schools and 1,917 neighborhoods. Approximately 51% (7,111) young adults were hypertensive. Individual-level characteristics-particularly older ages, Non-Hispanic Black race, Asian race, male sex, BMI, and current smoking-were associated with increased hypertension. Non-Hispanic Black (OR = 1.21; 95% CI: 1.03-1.42) and Asian (OR = 1.28; 95% CI: 1.02-1.62) students had higher odds of hypertension compared to non-Hispanic White students. At the school level, hypertension was associated with the percentage of non-Hispanic White students (OR for 10% higher = 1.06; 95% CI: 1.01-1.09). Adjusting for individual, school, and neighborhood predictors attenuated the ICC for both the school (from 1.4 null to 0.9 fully-adjusted) and neighborhood (from 0.4 to 0.3).

CONCLUSION

We find that adolescents' schools and individual-level factors influence young adult hypertension, more than neighborhoods. Unequal conditions in school environments for adolescents may increase the risk of hypertension later in life. Our findings merit further research to better understand the mechanisms through which adolescents' school environments contribute to adult hypertension and disparities in hypertension outcomes later in life.

Retail food outlets and metabolic syndrome: a systematic review of longitudinal studies

CONTEXT

The community food environment covers the type, quantity, density, location, and access to retail food outlets, and its influence on eating behavior, obesity, and metabolic syndrome has been investigated.

OBJECTIVE

To evaluate the evidence on longitudinal associations between objectively measured retail food outlets and metabolic syndrome components in children, adolescents, and adults.

DATA EXTRACTION

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study quality and risk of bias were assessed with the Newcastle-Ottawa Scale.

DATA SOURCES

The Scopus, Embase, Web of Science, Scielo, PubMed, MEDLINE, and Lilacs databases were searched without any restriction on publication dates.

DATA ANALYSIS

Of the 18 longitudinal studies included, significant associations were reported in 9 between retail food outlets and metabolic syndrome components in adults (6 positive associations, 2 negative, and 1 both positive and negative), and in 3 studies of children and adolescents (2 negative associations and 1 both positive and negative). Six studies with adults found no association.

CONCLUSION

Limited evidence was found for longitudinal associations between retail food outlets and metabolic syndrome components. In future studies, researchers should consider the use of standardized retail food outlet measurements and accurate analysis to better understand the influence of the community food environment on metabolic syndrome.

The pressure's on: understanding neurocognitive and psychological associations with pediatric hypertension to inform comprehensive care

The prevalence of hypertension is increasing in pediatric populations. While clinical data and practice guidelines identify the impact of hypertension on organ dysfunction and emphasize the importance for end-organ damage screening, the bidirectional effects of pediatric hypertension on neurocognitive and psychological outcomes are understudied. The objective of this review is to highlight the association between hypertension and cognition, attention, learning, and mental health in children and adolescents. In doing so, this review provides a framework and toolkit to integrate neuropsychology and psychology into the screening and management stages of pediatric hypertension. By recognizing the effects of hypertension on cognition, behavior, and mental health, screenings and interventions can be implemented to proactively and comprehensively improve the health outcomes for children with blood pressure concerns.
