RESUMEN
AIM: Study the association between neighbourhood risk and behaviour in extreme preterm (EPT) children. We hypothesised that EPT children living in high-risk neighbourhoods have increased risk of clinical range behaviour problems at age 30-36 months. METHODS: Retrospective analyses of Child Behavior Checklist (CBCL)scores for 739 EPTs born 2005-2016. Addresses were geocoded to identify census block groups and create high versus low-risk groups. Regression analyses assessed the impact of neighbourhood risk on behaviour. RESULTS: Children from high-risk (N = 272, 39%) and low-risk (N = 417, 61%) neighbourhoods were compared. In adjusted analyses, odds of clinical range scores remained greater in high-risk neighbourhoods for Emotionally Reactive (OR: 4.32, CI: 1.13, 16.51), Somatic Complaints (2.30, CI 1.11,4.79), Withdrawn (OR: 2.56, CI: 1.21, 5,42), Aggressive Behaviour (OR: 4.12, CI: 1.45, 11.68), Internalising (OR: 1.96, CI: 1.17, 3.28), and Total score (OR: 1.86, OR: CI: 1.13, 3.07). Cognitive delay was higher in high-risk neighbourhoods and a risk factor for Attention Problems (2.10,1.08, 4.09). Breast milk was protective for Emotionally Reactive (OR: 0.22, CI: 0.06, 0.85) and Sleep Problems (OR: 0.47, CI:0.24, 0.94). CONCLUSION: Neighbourhood risk provided an independent contribution to preterm adverse behaviour outcomes with cognitive delay an additional independent risk factor. Breast milk at discharge was protective.

Peer alcohol use, commonly assessed via perceptions of how many drinks peers consume, is a robust predictor of college drinking. These perceptions are formed by in-person exposure to peer drinking but also may be affected by seeing alcohol-related content (ARC) shared on peer social media accounts. Most research assesses exposure by asking about the frequency of ARC sharing by a whole friend group, potentially missing influences from specific friends. Social network methods collect information about specific friends and their behavior but few studies have used these methods to examine the effects of ARC on drinking, nor have they examined potential moderators of this relationship. The purpose of this study was to examine whether perceived frequency of exposure to ARC shared by social network members on social media is associated with participant alcohol use after controlling for network members' self-reported alcohol use, and if participant gender and relationship qualities with network members moderate this association. Participants were 994 college students (Mage = 21.17, SD = 0.47; 61.8 % female; 55.4 % White; 12.3 % Hispanic) who completed a web-based survey. Due to the social network design, network autocorrelation analyses were conducted, which revealed that greater perceived frequency of exposure to network member ARC was significantly associated with higher alcohol quantity above and beyond network members' alcohol use. Peer ARC had a unique association with drinking behavior independent of in-person peer alcohol use, although the cross-sectional design precludes making causal inferences. Clinicians delivering alcohol interventions to college students may wish to discuss exposure to ARC as another important source of peer influence and how media literacy may help reduce the effects.

BACKGROUND: The COVID-19 pandemic negatively affected adolescent mental health due to school closures, isolation, family loss/hardships, and reduced health care access. METHODS: We compared adolescent mental health in Rhode Island before versus during the pandemic, separately among middle and high schoolers. This serial cross-sectional study used Youth Risk Behavior Survey data from 2019 and 2021 (N = 7403). Multivariable logistic regression models estimated the association between year and mental health status, adjusting for sociodemographics. RESULTS: Middle schoolers in 2021 had higher odds of ever seriously considering suicide (22.6% vs 16.7%) and ever attempting suicide (9.3% vs 6.1%) compared to 2019. Among high schoolers, those in 2021 had higher odds of experiencing persistent sadness/hopelessness in the past year (37.4% vs 32.0%). However, high schoolers in 2019 and 2021 had similar odds of considering suicide in the past year, while those in 2021 had lower odds of having attempted suicide in the past year (8.5% vs 14.6%). CONCLUSION: The COVID-19 pandemic may have worsened multiple aspects of adolescent mental health in Rhode Island, particularly among middle schoolers. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Promoting school connectedness, creating supportive environments, and diversifying the mental health workforce may help overcome adverse pandemic effects.

BACKGROUND: Although viral infections, including SARS-CoV-2, can cause persistent symptoms and functional limitations, the impact of post-viral syndromes on workplaces is uncertain. METHODS: We conducted a cross-sectional study of workplaces in Rhode Island in the D&B Hoovers database (September-October 2022). Eligible workplaces had ≥1 contact with a valid email address and ≥2 paid employees. Participants completed a survey on the impact of Long COVID (post-viral syndrome of SARS-CoV-2) on their workplace. RESULTS: Of 6,149 eligible workplaces, 484 (8%) participated. Awareness of Long COVID among workplace leaders was limited. Overall, 28% of workplaces had any employees report having Long COVID. Of those, 14% had ≥1 employee discontinue employment, 45% had ≥1 employee reduce their workload, and 22% had ≥1 employee request an accommodation due to having Long COVID; 80% of employers reported improvement in employee productivity with accommodations. CONCLUSION: Pandemic preparations for the long-term impacts of post-viral syndromes should consider workplace settings.

BACKGROUND: To assess the persistence of neighborhood-level lead poisoning disparities in Rhode Island. METHODS: Rhode Island Department of Health blood lead levels (BLL) collected from 2006-2019 were linked to census block group rates of poverty and housing built pre-1950. We computed multivariate logistic regression models of elevated BLLs (≥5 µg/dL and ≥10 µg/dL). RESULTS: Of the 197,384 study children, 12.9% had BLLs ≥5 µg/dL and 2.3% had BLLs ≥10 µg/dL. The proportion of children with BLL ≥ 5 µg/dL increased across quintiles of poverty and old housing. The odds ratio for highest quintiles was 1.44 (95% CI: 1.29, 1.60) and 1.92 (95% CI: 1.70, 2.17) for poverty and pre-1950 housing, respectively. A significant temporal decline was observed for BLL ≥ 5 µg/dL (2006: 20.5%, 2019: 3.6%). Disparities narrowed over the study period across quintiles of poverty and old housing with a similar trend appearing in the proportion of children with BLL ≥ 10 µg/dL. CONCLUSION: Despite tremendous progress in reducing lead exposure, substantial neighborhood disparities in lead poisoning persist. These findings provide valuable considerations for primary childhood lead exposure prevention. IMPACT: Through linkage of Rhode Island Department of Health childhood lead poisoning and census data, this study captures neighborhood-level disparities in lead poisoning from 2006-2019. This study demonstrates that the odds of lead poisoning increased in a stepwise fashion for neighborhood quintiles of poverty and housing built pre-1950. While the magnitude of lead poisoning disparities narrowed across quintiles of poverty and old housing, disparities persist. Children's exposure to sources of lead contamination continues to be an important public health concern. The burden of lead poisoning is not equally distributed among all children or communities.

BACKGROUND: Evidence of a biologically plausible association between maternal smoking during pregnancy (MSP) and the risk of depression is discounted by null findings from two sibling studies. However, valid causal inference from sibling studies is subject to challenges inherent to human studies of MSP and biases particular to this design. We addressed these challenges in the first sibling study of MSP and depression conducted among adults past the peak age for the onset of depression, utilizing a prospectively collected and biologically validated measure of MSP and accounting for non-shared as well as mediating factors. METHODS: We fit GEE binomial regression models to correct for dependence in the risk of depression across pregnancies of the same mother. We also fit marginal structural models (MSM) to estimate the controlled direct effect of MSP on depression that is not mediated by the offspring's smoking status. Both models allow the estimation of within- and between-sibling risk ratios. RESULTS: The adjusted within-sibling risk ratios (RRW) from both models (GEE: RRW = 1.97, CI 1.16-3.32; MSM: RRW = 2.08, CI 1.04-4.17) evinced an independent association between MSP and risk of depression. The overall effects from a standard model evinced lower associations (GEE: RRT = 1.12, CI 0.98-1.28; MSM: RRT = 1.18, CI 1.01-1.37). CONCLUSIONS: Based on within-sibling information free of unmeasured shared confounders and accounting for a range of unshared factors, we found an effect of MSP on the offspring's risk of depression. Our findings, should they be replicated in future studies, highlight the importance of considering challenges inherent to human studies of MSP and affective disorders.

OBJECTIVES: This study aimed to describe which infants with a skull fracture (1) receive a child abuse pediatrician (CAP) consultation, (2) receive a skeletal survey, and (3) re-present to medical care before age 3 years with concerns for physical abuse. METHODS: We conducted a retrospective chart review of infants younger than 12 months who presented to the emergency department between January 1, 2005, and December 30, 2015, with a skull fracture. Medical records were reviewed for the skull fracture presentation and for all future medical evaluations at the same institution with concerns for physical abuse until 3 years of age. RESULTS: Of 366 infants with a skull fracture, a CAP was contacted for 272 (74%) and 76 (20.8%) infants who received a skeletal survey. Factors associated with skeletal survey acquisition included younger age (<6 months), no history to explain the skull fracture, other injuries on examination, and social risk factors. Six children (1.6%) re-presented to medical care with concerns of physical abuse before age 3 years. Five of these infants did not have a skeletal survey at the time of their skull fracture, and 1 was likely a case of missed physical abuse at the time of the skull fracture. DISCUSSION: Most skull fractures in infancy occur accidentally, and a skeletal survey may not be necessary for every infant. Obtaining a thorough history including social risk factors, performing a complete physical examination, and consulting with a CAP is an effective first step in the evaluation of physical abuse in infants with skull fractures.

OBJECTIVE: To study the association between neighborhood risk and moderate to severe neurodevelopmental impairment (NDI) at 22-26 months corrected age in children born at <34 weeks of gestation. We hypothesized that infants born preterm living in high-risk neighborhoods would have a greater risk of NDI and cognitive, motor, and language delays. STUDY DESIGN: We studied a retrospective cohort of 1291 infants born preterm between 2005 and 2016, excluding infants with congenital anomalies. NDI was defined as any one of the following: a Bayley Scales of Infant and Toddler Development-III Cognitive or Motor composite score <85, bilateral blindness, bilateral hearing impairment, or moderate-severe cerebral palsy. Maternal addresses were geocoded to identify census block groups and create high-risk versus low-risk neighborhood groups. Bivariate and regression analyses were run to assess the impact of neighborhood risk on outcomes. RESULTS: Infants from high-risk (n = 538; 42%) and low-risk (n = 753; 58%) neighborhoods were compared. In bivariate analyses, the risk of NDI and cognitive, motor, and language delays was greater in high-risk neighborhoods. In adjusted regression models, the risks of NDI (OR, 1.43; 95% CI, 1.04-1.98), cognitive delay (OR, 1.62; 95% CI, 1.15-2.28), and language delay (OR, 1.58; 95% CI, 1.15-2.16) were greater in high-risk neighborhoods. Breast milk at discharge was more common in low-risk neighborhoods and was protective of NDI in regression analysis. CONCLUSIONS: High neighborhood risk provides an independent contribution to preterm adverse NDI, cognitive, and language outcomes. In addition, breast milk at discharge was protective. Knowledge of neighborhood risk may inform the targeted implementation of programs for socially disadvantaged infants.

OBJECTIVE: This research aims to take an in-depth look into the child, housing, and neighborhood characteristics associated with Providence children's likelihood of having elevated blood lead levels (BLLs). DESIGN AND SETTING: The 2019 Providence, Rhode Island, Property Tax Assessor's database, containing each property owner's address, was geocoded and spatially joined with the 2017-2019 blood lead tests for children aged 0 to 6 years from the Rhode Island Department of Health. MAIN OUTCOME MEASURES: The prevalence of elevated BLLs (≥5 µg/dL) overall, as well as by property type, number of properties owned, owner occupancy, assessed value, and neighborhood rates of old housing and poverty, was computed. We assessed the relationship between having elevated BLLs and these housing and neighborhood characteristics, adjusting for gender, age at test, and test method. RESULTS: We found that, compared with children living in properties with landlords who owned only one property, children living in properties with landlords who owned 4 or more properties had lower odds of having elevated BLLs (odds ratio = 0.98; 95% confidence interval, 0.97-0.99). The proportion of houses built pre-1950 in the neighborhood was associated with increased odds of elevated BLLs. There was no significant association between owner-occupancy status and property type with children having elevated BLLs. CONCLUSIONS: Children living in properties with landlords who owned 4 or more properties were less likely to have elevated BLLs. This association may suggest that the current lead legislation is having some impact, but public health efforts should address lead exposure in properties that are currently exempt from the law.

BACKGROUND: Alcohol use shows age-graded patterning, with normative use progressing through characteristic milestones of escalating use or severity. Despite some knowledge about the timing of milestone attainment and sequencing across milestones, there is a gap in our understanding of the earliest stages of use. This study characterizes the timing, sequencing, and speed of progression through milestones beginning with the first sip of alcohol. METHODS: Sixth through eighth graders (N = 1023; 52% female; 76% White; M = 12.23 years old) completed web surveys through the end of high school. Participants reported on alcohol experiences including the first sip, full drink, consumption of 3+ drinks/occasion (heavy drinking), being drunk, and experiencing acute consequences, from which milestone age and speed of progression (duration) were calculated. Milestone prevalence, sequencing, and timing were characterized, and associations between age of attainment and speed of progression were examined. We also examined whether milestone timing and progression varied by sex and racial/ethnic group. RESULTS: Overall, milestones followed the expected ordering with the exception of heavy drinking (3+ drinks/occasion) and being drunk, which appear to index similar experiences. An earlier age of attainment was associated with an increased likelihood of attaining each of the milestones. In contrast, once a milestone was achieved, there was reduced risk of initiation of subsequent adjacent milestones for individuals with an earlier first sip and full drink, and earlier initiation was associated with a longer duration to subsequent milestones. Girls were more likely to attain all milestones than boys, but there was no sex difference in the age of attainment. In contrast, Hispanic youth reported earlier ages of initiation than White non-Hispanic youth, but the likelihood of attainment did not vary by race/ethnicity. Rapid progression was observed in females but did not vary by race/ethnicity. DISCUSSION: Risks associated with early drinking are complex, with little support for normative ordering of milestones beyond the first sip. Although early drinking is associated with an increased risk of subsequent drinking, it does not appear to place the drinker on an accelerated course to heavier use. A nuanced understanding of risks associated with milestone timing may inform intervention efforts.

BACKGROUND: Burn injury continues to cause significant morbidity and mortality in the US pediatric population. Many studies using inpatient samples have found a relationship between low socioeconomic status (SES) and burn injury. The purpose of our study was to evaluate the association between SES and the likelihood of admission for Emergency Department (ED) visits for pediatric burn injury. STUDY DESIGN: A retrospective database review of pediatric ED visits for burn injury from a statewide hospital system, from January 1, 2005 to December 31, 2014. SES was assigned using an eight factor Neighborhood Risk Index (NRI) created from census block group data, with a higher score indicative of lower SES. The outcome measure was ED visits admitted to inpatient care. RESULTS: We analyzed a sample of 1845 pediatric ED visits for burn injuries. Most visits were discharged from the ED (88.4%) while 10.5% were admitted to inpatient care and 1.0% were transferred to another hospital. In a multivariable logistic regression model, patients from high risk areas (>75th percentile NRI) had 1.58 higher odds of inpatient admission compared to patients from low risk areas (<75th percentile NRI; 95% CI: 1.08-2.30), after adjusting for age, gender, ethnicity, distance to the hospital, and previous ED visit for burn injury in the past 30 days. In addition, for every 1-mile increase in distance, a child's likelihood of admission increased by 6% (95% CI: 4-9%). CONCLUSIONS: Children with a burn injury from the highest risk socioeconomic areas in Rhode Island had a higher likelihood of inpatient admission. Further research is needed to determine what factors associated with socioeconomic status impact this finding.

OBJECTIVE: This study seeks to better understand the relationship between the physical activity environment and child overweight/obesity in Rhode Island. METHODS: Using geographic information systems (GIS), this study calculated distances from residences to physical activity resources to assess the relationship distance has with childhood overweight/obesity. RESULTS: Mean distances in high-risk towns ranged from 0.61 to 3.15 miles compared to physical activity resources in low-risk towns, where distances ranged from 1.25 to 7.43 miles. For each additional mile to reach the closest indoor facility, there is a 0.41 (95% CI: -0.78, -0.03) percentage point decrease in the child overweight/obesity rate. Conclusion: High-risk block groups and towns have higher rates of child overweight/obesity and show shorter distances to physical activity resources. This study demonstrates that simply having physical activity structures in place is not enough to reduce child overweight/obesity and further research should examine the quality and usage patterns of these resources.

Objectives. To characterize statewide seroprevalence and point prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Rhode Island.Methods. We conducted a cross-sectional survey of randomly selected households across Rhode Island in May 2020. Antibody-based and polymerase chain reaction (PCR)-based tests for SARS-CoV-2 were offered. Hispanics/Latinos and African Americans/Blacks were oversampled to ensure adequate representation. Seroprevalence estimations accounted for test sensitivity and specificity and were compared according to age, race/ethnicity, gender, housing environment, and transportation mode.Results. Overall, 1043 individuals from 554 households were tested (1032 antibody tests, 988 PCR tests). The estimated seroprevalence of SARS-CoV-2 antibodies was 2.1% (95% credible interval [CI] = 0.6, 4.1). Seroprevalence was 7.5% (95% CI = 1.3, 17.5) among Hispanics/Latinos, 3.8% (95% CI = 0.0, 15.0) among African Americans/Blacks, and 0.8% (95% CI = 0.0, 2.4) among non-Hispanic Whites. Overall PCR-based prevalence was 1.5% (95% CI = 0.5, 3.1).Conclusions. Rhode Island had low seroprevalence relative to other settings, but seroprevalence was substantially higher among African Americans/Blacks and Hispanics/Latinos. Rhode Island sits along the highly populated northeast corridor, making our findings broadly relevant to this region of the country. Continued monitoring via population-based sampling is needed to quantify these impacts going forward.

OBJECTIVES: Frequent use of the emergency department (ED) is often targeted as a quality improvement metric. The objective of this study was to assess ED visit frequency by the demographic and health characteristics of children who visit the ED to better understand risk factors for high ED utilization. METHODS: The majority of pediatric ED services in Rhode Island are provided by a hospital network that includes the state's only children's hospital. Using 10 years of data (2005-2014) from this statewide hospital network, we examined ED use in this network for all children aged 0 to 17 years. Patients' home addresses were geocoded to assess their neighborhood characteristics. RESULTS: Between 2005 and 2014, 17,844 children visited 1 or more of the network EDs at least once. In their year of maximum use, 67.8% had only 1 ED visit, 20.1% had 2 visits, 6.9% had 3 visits, and 5.2% had 4 or more visits. In the adjusted multinomial logistic regression model, age, race/ethnicity, language, insurance coverage, medical complexity, neighborhood risk, and distance to the ED were found to be significantly associated with increased visit frequency. CONCLUSIONS: Risk factors for frequent ED use by children include age, race/ethnicity, language, insurance coverage, medical complexity, neighborhood risk, and distance to the hospital. To decrease frequent pediatric ED use, improved medical management of complex medical problems is needed, but it is also essential to address modifiable social determinants of health care utilization in this population.

BACKGROUND: This study examined how proximity to food sources differed at the block group and town level, stratified by socioeconomic risk, and how the average distance to a food source was associated with child overweight and obesity rates in Rhode Island. METHODS: Eight correlated variables from the 2014-2018 American Community Survey were used to measure high and low socioeconomic risk at the block group and town level. Linear regression models were used to assess the association between mean driving distance to food sources and prevalence of child overweight and obesity. RESULTS: All food sources were closer to residences in the high-risk group than the low-risk group at the block group and town level. Convenience stores, sit-down restaurants, and snack and beverage stores showed the largest associations with prevalence of overweight and obesity. CONCLUSION: Efforts to better understand the food environment are needed to address overweight and obesity among youth.

This work describes a fully-integrated portable microfluidic analysis system for real-time monitoring of dynamic changes in glucose and lactate occurring in the brain as a result of cardiac arrest and resuscitation. Brain metabolites are sampled using FDA-approved microdialysis probes and coupled to a high-temporal resolution 3D printed microfluidic chip housing glucose and lactate biosensors. The microfluidic biosensors are integrated with a wireless 2-channel potentiostat forming a compact analysis system that is ideal for use in a crowded operating theatre. Data are transmitted to a custom-written app running on a tablet for real-time visualisation of metabolic trends. In a proof-of-concept porcine model of cardiac arrest, the integrated analysis system proved reliable in a challenging environment resembling a clinical setting; noise levels were found to be comparable with those seen in the lab and were not affected by major clinical interventions such as defibrillation of the heart. Using this system, we were able, for the first time, to measure changes in brain glucose and lactate levels caused by cardiac arrest and resuscitation; the system was sensitive to clinical interventions such as infusion of adrenaline. Trends suggest that cardiopulmonary resuscitation alone does not meet the high energy demands of the brain as metabolite levels only return to their values preceding cardiac arrest upon return of spontaneous circulation.

Parental knowledge about adolescents' whereabouts and activities remains one of the strongest predictors of reduced adolescent substance use. A recent study found that across middle childhood and adolescence, parental knowledge is characterized by fluctuations on a year-to-year basis, termed lability, even more-so than by linear trends, and that lability too is a predictor of adolescent substance use (Lippold et al., Dev. Psychol. 17, 274-283, 2016). The present study replicates Lippold et al. (Dev. Psychol. 17, 274-283, 2016) by quantifying developmental change and lability in parental knowledge across adolescence and examining associations with drinking, smoking, and other drug use later in adolescence, and extends the study by examining the sources of knowledge: child disclosure, parental solicitation, and parental control, separately. Using a community-based sample of 1023 youth in the Northeastern region of the USA, all three sources of knowledge were characterized by developmental change and lability. In general, higher levels and steeper developmental declines in knowledge were associated with substance use outcomes. Findings for child disclosure replicated the prior findings: increased lability of child disclosure predicted substance use. Unexpectedly, decreased lability of parental solicitation and control was associated with worse substance use outcomes. Findings suggest different mechanisms by which lability in child- and parent-driven cultivation of knowledge is associated with substance use. If replicated in studies that address causality, these mechanisms could be leveraged for prevention/intervention efforts. For example, increasing the consistency of child disclosure may help prevent substance use, but teaching parents to be more responsive to time-specific challenges with adolescents may be more effective than increasing the consistency of parents' knowledge-building parenting behaviors.

OBJECTIVES: To analyze the distribution of patient-centered medical homes (PCMHs) among US adolescents, and to examine whether disparities exist among subgroups. STUDY DESIGN: Data on adolescents ages 12-17 years (n = 34â601) from the 2011-2012 National Survey of Children's Health were used in this cross-sectional study to determine what proportion had access to a PCMH. Multivariable logistic regression was used to calculate the odds of having a PCMH, adjusting for sociodemographic characteristics and special health care needs. Comparisons were made to distribution of PCMH in 2007. RESULTS: Although most US adolescents had a usual source of care (91%), only about one-half (51%) had access to a PCMH. Disparities in the prevalence of PCMHs were seen by race/ethnicity, poverty, and having special health care needs. There were lower adjusted odds in having a PCMH for Hispanic (aOR, 0.56; 95% CI, 0.45-0.68) and black adolescents (aOR, 0.55; 95% CI, 0.46-0.66) compared with white adolescents. Those living below 4 times the poverty level had lower adjusted odds of PCMH access. Adolescents with 3-5 special health care needs had lower adjusted odds (aOR, 0.43; 95% CI, 0.35-0.52) of having a PCMH compared with adolescents without any special health care needs. Other than receiving family centered care, every component of PCMH was slightly lower in 2011-2012 compared with 2007. CONCLUSIONS: PCMH access was lower among minorities, those living in poverty, and those with multiple special health care needs. These disparities in PCMH access among these typically underserved groups call for further study and interventions that would make PCMHs more accessible to all adolescents.
