The association between witnessing firearm violence and firearm carriage: Results from a national study of teens.

The association between witnessing firearm-involved violence and firearm carriage among teens, independent of non-firearm involved violence, has yet to be identified. The present analyses estimate associations of witnessing firearm-involved violence and non-firearm involved violence with firearm carriage in a nationally representative sample of teens. Data are from the FACTS National Survey-a cross-sectional web-based survey of 2140 US teenagers (ages 14-18) fielded in June-July 2020. The team first estimated the correlation between witnessing firearm-involved and non-firearm involved violence. Bivariate and multivariable logistic regression then assessed the associations of witnessing firearm-involved and non-firearm involved violence with firearm carriage. The team pooled results over fifteen imputed datasets to account for missing data, and analyses incorporated survey weights to create nationally representative estimates. The correlation between witnessing firearm-involved and non-firearm involved violence was low (ϕ = 0.19[0.15, 0.23]). Witnessing firearm-involved violence and witnessing non-firearm involved violence were both associated with teen firearm carriage in bivariate models (OR: 3.55[1.86, 6.79]; 4.51[1.75, 11.6]). These associations persisted in the multivariable model that adjusted for violence victimization, demographic characteristics, and both witnessing firearm-involved and non-firearm involved violence (aOR for witnessing firearm-involved violence = 3.67[1.77, 7.59]; aOR for witnessing non-firearm involved violence = 4.30[1.56, 11.9]). We found no difference in the strength of these associations (Wald χ2(df = 1) = 0.25, p = 0.80). Results suggest that witnessing firearm-involved and non-firearm involved violence are uniquely associated with teens' firearm carriage. Identifying means to reduce both exposures, in addition to recognizing factors that may weaken the associations between witnessing different types of violence and firearm carriage, may disrupt cycles of violence.

The association between perceived community violence, police bias, race, and firearm carriage among urban adolescents and young adults.

Firearms are a leading cause of death among youth and young adults. Given community violence is an important correlate of youth firearm carriage, we evaluated: 1) If the association between perceived community violence and firearm carriage is stronger when perceived police bias is greater; and 2) If this moderated association differs by race. Cross-sectional data came from screening data for a longitudinal study of firearm behaviors among young adults seeking urban emergency department treatment between July 2017-June 2018 (N = 1264). We estimated Poisson regressions with robust error variance to evaluate associations between perceived community violence, police bias, race, and firearm carriage. Community violence was positively associated with firearm carriage (average marginal effect [AME]: 0.05; 95% Confidence Interval [CI]: 0.03, 0.07). We also found that the positive association between community violence and firearm carriage increased with higher perceptions of police bias (interaction p < 0.05). We did not find evidence of a three-way interaction by which the moderated association between violence exposure and firearm carriage by perceived police bias varied by race of the respondents. Our findings suggest that community-level strategies to reduce violence and police bias may be beneficial to decrease youth firearm carriage in socio-economically disadvantaged urban settings.

Is late bedtime an overlooked sleep behaviour? Investigating associations between sleep timing, sleep duration and eating behaviours in adolescence and adulthood.

OBJECTIVE: To examine whether bedtime is associated with usual sleep duration and eating behaviour among adolescents, emerging adults and young adults. DESIGN: Cross-sectional multivariable regression models, stratified by developmental stage, to examine: (1) association between bedtime and sleep duration and (2) associations between bedtime and specific eating behaviours at each developmental period, controlling for sleep duration. All models adjusted for sociodemographic characteristics, depressive symptoms and screen time behaviours. SETTING: National Longitudinal Study of Adolescent to Adult Health, waves I-IV, USA. PARTICIPANTS: A national probability sample surveyed in adolescence (aged 12-18 years, wave I: 1994-1995, n 13 048 and wave II: 1996, n 9438), emerging adulthood (aged 18-24 years, wave III: 2001-2002, n 9424) and young adulthood (aged 24-34 years, wave IV: 2008, n 10 410). RESULTS: Later bedtime was associated with shorter sleep duration in all developmental stages, such that a 1-h delay in bedtime was associated with 14-33 fewer minutes of sleep per night (Ps < 0·001). Later bedtime was also associated with lower odds of consuming healthier foods (i.e. fruits, vegetables; range of adjusted OR (AOR), 0·82-0·93, Ps < 0·05) and higher odds of consuming less healthy foods and beverages (i.e. soda, pizza, desserts and sweets; range of AOR, 1·07-1·09, Ps < 0·05). Later bedtime was also associated with more frequent fast-food consumption and higher sugar-sweetened beverage consumption (Ps < 0·05). CONCLUSIONS: Later bedtime was associated with shorter sleep duration and less healthy eating behaviours. Bedtime may be a novel behaviour to address in interventions aiming to improve sleep duration and dietary intake.

Why some parents made firearms more accessible during the beginning of the COVID-19 pandemic: results from a national study.

The objective of this study was to assess parents' firearm storage behaviors during the COVID-19 pandemic and characterize reasons why some parents made their firearms more accessible during this time. In June-July 2020, the study team conducted the FACTS National Survey-a cross-sectional, web-based, survey of 2,924 parents and their teens (ages14-18) regarding firearm-related practices. We weighted descriptive analyses to be nationally representative of parents of teens in the United States. We utilized qualitative thematic analysis to identify parents' reasons for making firearms more accessible. Five percent of firearm-owning parents of teens reported making their firearms more accessible during the beginning of the COVID-19 pandemic. Reasons why parents increased the ease of firearm access included: (1) Increased civil unrest and riots; (2) Threat of home invasion and/or crime victimization; (3) Fear of panic and the unknown; and (4) Easier access and greater protection, threat unspecified. Some parents-largely motivated by fear-chose to store firearms in a more accessible manner during the beginning of the COVID-19 pandemic to protect their family against possible external threats. Understanding the fear that motivates parents' decisions regarding storage practices might aid interventions focused on harm reduction and safer storage.

Firearm purchasing during the beginning of the COVID-19 pandemic in households with teens: a national study.

To describe and identify the correlates of firearm purchasing at the beginning of the COVID-19 pandemic among US families with teenagers. In June-July 2020, we conducted a national survey of 2924 parents and their teenagers in the US. We report results from this survey to describe firearm purchasing behaviors following the start of the COVID-19 pandemic and investigate correlates of purchasing. Between the beginning of the pandemic and July 2020, 10% of households with teenagers purchased a firearm, and 3% became first-time firearm-owning households. Among firearm-owning households, firearm storage was associated with purchasing such that households that stored at least one firearm loaded and unlocked were more likely to purchase a firearm (OR: 2.02[1.07-3.79]) compared to households that stored all firearms unloaded and/or locked. Firearms purchased at the beginning of the pandemic were more likely to go to homes where at least one firearm was stored loaded and unlocked, which may contribute to increased risk for teen firearm injury and death.

Sleep duration and body mass: direction of the associations from adolescence to young adulthood.

Research suggests that sleep duration and obesity are related, but the direction of this association remains uncertain. We applied autoregressive cross-lag models to evaluate the directionality of the relationship between sleep duration and BMI from adolescence through emerging and young adulthood, life stages where the risk for developing obesity are particularly high. Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we examined sex-stratified associations between sleep duration and BMI in this cohort from adolescence (ages 12-18, year 1996), to emerging adulthood (ages 18-24, 2001-2002), to young adulthood (ages 24-32, 2008), controlling for key confounders. For both males and females, higher BMI during an earlier developmental stage was associated with shorter sleep duration in the subsequent stage (both Bs = -0.02, ps < 0.01). However, sleep duration at an earlier developmental stage was not associated with BMI at the subsequent stage. Findings suggest that researchers should be cautious when interpreting cross-sectional relationships between sleep and BMI, as higher BMI may precede shorter sleep during adolescence to young adulthood. Researchers may also wish to account for potential bi-directional associations when modeling sleep and BMI using longitudinal data.

Developmental Differences in the Association of Peer Relationships with Traumatic Stress Symptoms.

Although childhood trauma exposure has a high incidence, traumatic stress often goes untreated in children and youth. We investigated peer relationship quality as a prevention strategy for reducing traumatic stress across different developmental periods. We analyzed longitudinal data from the National Survey of Child and Adolescent Wellbeing (NSCAW I) using a time-varying effect model (TVEM) to investigate the association between peer relationship quality and traumatic stress symptoms across ages 8-17 years. We controlled for a robust set of confounders identified through a Directed Acyclic Graph (DAG). The unique association between peer relationship quality and traumatic stress symptoms was negative and significant from ages 8 to 8.5 years, and again from ages 9.4 to 10.9 years and at age 16.4 to 16.8 years, with maximum associations of - 1.45 T score points at age 8.5 years (95% CI = [- 2.87, - 0.40]), - 1.57 at age 9.4 years (95% CI = [- 3.13,- 0.01]), and - 1.89 at 16.7 years (95% CI = [- 3.70, - 0.09]). Peer relationship quality protected against traumatic stress during specific times during adolescent development. Our results suggest that helping youth establish and maintain positive peer relationships may be a useful prevention approach for helping them cope with trauma experiences.

Transitions into and out of post-traumatic stress among children involved in the child welfare system.

PURPOSE: To describe the transition patterns into and out of post-traumatic stress (PTS) for youth and identify social supports preceding these transitions. METHODS: We used inhomogeneous, continuous-time, 1Markov Chain models to model transitions in and out of PTS using data from Waves 1, 3, 4, and 5 of the National Survey of Child and Adolescent Wellbeing (NSCAW I)-a longitudinal study of children who first had contact with the child welfare system between 1999 and 2000. Our analytic sample contained 915 individuals aged 11-17 years. We analyzed data in 2020. RESULTS: Youth with stronger peer relationships were less likely to transition into PTS (HR: 0.82; 95% CI [0.70-0.96]), and these individuals were also more likely to transition out of PTS (HR: 1.21; 95% CI [1.04, 1.42]). Youth with adult support were less likely to transition into PTS at any given time interval (HR: 0.37; 95% CI [0.17-0.78]), but adult support was not associated with the transition out of PTS. CONCLUSIONS: Strengthening peer relationships may help at-risk children both avoid PTS altogether and recover from PTS after its onset. Promoting adult support, however, may only be most effective when attempting to prevent PTS-onset.

Does a parsimonious measure of complex body mass index trajectories exist?

BACKGROUND: A single measure that distills complex body mass index (BMI) trajectories into one value could facilitate otherwise complicated analyses. This study creates and assesses the validity of such a measure: average excess BMI. METHODS: We use data from Waves I-IV of the National Longitudinal Study of Adolescent to Adult Health (n = 17,669). We calculate average excess BMI by integrating to find the area above a healthy BMI trajectory and below each subject-specific trajectory and divide this value by total study time. To assess validity and utility, we (1) evaluate relationships between average excess BMI from adolescence to adulthood and adult chronic conditions, (2) compare associations and fit to models using subject-specific BMI trajectory parameter estimates as predictors, and (3) compare associations to models using BMI trajectory parameter estimates as outcomes. RESULTS: Average excess BMI from adolescence to adulthood is associated with increased odds of hypertension (OR = 1.56; 95% CI: 1.47, 1.67), hyperlipidemia (OR = 1.36; 95% CI: 1.26, 1.47), and diabetes (OR = 1.57; 95% CI: 1.47, 1.67). The odds associated with average excess BMI are higher than the odds associated with the BMI intercept, linear, or quadratic slope. Correlations between observed and predicted health outcomes are slightly lower for some models using average excess BMI as the focal predictor compared to those using BMI intercept, linear, and quadratic slope. When using trajectory parameters as outcomes, some co-variates associate with the intercept, linear, and quadratic slope in contradicting directions. CONCLUSIONS: This study supports the utility of average excess BMI as an outcome. The higher an individual's average excess BMI from adolescence to adulthood, the greater their odds of chronic conditions. Future studies investigating longitudinal BMI as an outcome should consider using average excess BMI, whereas studies that conceptualize longitudinal BMI as the predictor should continue using traditional latent growth methods.

Peer support opportunities across the cancer care continuum: a systematic scoping review of recent peer-reviewed literature.

OBJECTIVE: Evidence suggests peer support (PS) is as an effective strategy for enhancing prevention and control of chronic and infectious diseases, including cancer. This systematic scoping review examines the range and variety of interventions on the use of PS across the cancer care continuum. METHOD: We used a broad definition of PS to capture a wide-range of interventions and characterize the current status of the field. Literature searches were conducted using PubMed, SCOPUS, and CINAHL to identify relevant articles published from January 2011 to June 2016. We screened the title and abstracts of 2087 articles, followed by full-text screening of 420 articles, resulting in a final sample of 242 articles of which the most recent 100 articles were reviewed (published June 2014 to May 2016). RESULTS: A number of the recent intervention studies focused on breast cancer (32%, breast cancer only) or multiple cancer sites (23%). Although the interventions spanned all phases of the cancer care continuum, only 2% targeted end-of-life care. Seventy-six percent focused on clinical outcomes (e.g., screening, treatment adherence) and 72% on reducing health disparities. Interventions were primarily phone-based (44%) or delivered in a clinic setting (44%). Only a few studies (22%) described the impact of providing PS on peer supporters. CONCLUSION: PS appears to be a widely used approach to address needs across the cancer care continuum, with many opportunities to expand its reach.

Explaining Excessive Weight Gain during Early Recovery from Addiction.

BACKGROUND: Many people receiving treatment for addiction gain an excessive amount of weight during early recovery. We outline two hypothesized mechanisms that might explain weight gain: The Addiction Transfer Hypothesis, which suggests that some individuals respond to cravings with non-nutritive eating behavior, and the Propensity for Behavioral Addiction Hypothesis, which suggests that some people are at higher risk for addiction, and that excess weight gain results from a rebound of appetitive processes that were temporarily suppressed during active addiction. METHOD: We evaluate the extent of support for these alternative hypotheses using repeated measures of cravings and eating behavior collected in real time using a combination of ecological momentary assessment methodology and interviewer-based 24-hour dietary recall. Participants included N = 111 individuals receiving treatment for substance use disorder who were currently abstaining from use, but who had used their primary treatment substance within the past 12 months. RESULTS: Using linear mixed models to test the temporal effects of cravings on subsequent eating behaviors hypothesized by the Addiction Transfer Hypothesis and generalized linear models to evaluate the effect of a common propensity for behavioral addiction factor on eating behaviors (a test of the Propensity for Behavioral Addiction Hypothesis), we find no evidence to support the Addiction Transfer Hypothesis, but we find modest support for the Propensity for Behavioral Addiction Hypothesis. Findings do not account for appetitive effects of psychotropic medications. CONCLUSIONS: General nutrition education and encouragement of health eating behaviors may be useful for reducing excessive weight gain among people recovering from substance dependence.

Child Maltreatment and Body Mass Index over Time: The Roles of Social Support and Stress Responses.

An unhealthy body mass index (BMI) trajectory can exacerbate the burdens associated with child maltreatment. However, we have yet to explain why the relationship between maltreatment and BMI trajectories exists and what allows individuals to attain healthy BMI trajectories despite adversity. Guided by the Transactional Model of Stress and Coping, we evaluated (1) if peer friendship and adult mentors moderate, and (2) if impulsivity and depressive symptoms mediate, the relationship between maltreatment experiences and average excess BMI. We used data from four waves of the National Longitudinal Study of Adolescent to Adult Health (n = 17,696), following adolescents from ages 13-21 (Wave I) to 24-31 years (Wave IV). We did not find evidence of significant moderation or mediation of the maltreatment experience to average excess BMI relationship. However, models did demonstrate a relationship between peer friendship quality and average excess BMI, such that higher quality protected against higher average excess BMI (B = -0.073, s.e. = 0.02, p < 0.001). Age of maltreatment onset was also associated with average excess BMI, such that maltreatment onset in adolescence was associated with a higher average excess BMI (B = 0.275-0.284, s.e. = 0.11, p = 0.01). Although we found no evidence of moderation by social support or mediation by stress responses of the relationship between maltreatment experiences and average excess BMI, peer friendship appears to protect against higher average excess BMI from adolescence to young adulthood for all adolescents. Future public health interventions should consider how to leverage friendship in obesity prevention efforts.

Relationship between Child Maltreatment and Adolescent Body Mass Index Trajectories.

This study examines the relationship between childhood maltreatment experiences and body mass index (BMI) over time. Using data from the National Longitudinal Study of Adolescent to Adult Health, we use latent profile analysis to create child maltreatment experience classes and latent growth modeling to understand how classes relate to BMI trajectories from adolescence to early adulthood. The best-fitting model suggests four child maltreatment experience classes: 1) poly-maltreatment (n=607); 2) physical abuse (n=1,578); 3) physical abuse and neglect (n=345); and 4) no childhood maltreatment (n=4,188). Class membership differentially predicts BMI trajectories, such that individuals in the no maltreatment, physical abuse, and physical abuse plus neglect classes exhibit the most stable BMI, and individuals in the poly-maltreatment class increase most rapidly (Χ2[9]=149.9, p < 0.001). Individuals in the poly-maltreatment class experience significantly higher BMI over time compared to the other three classes. In addition to overall growth differing between classes, there is substantial inter-individual variability in BMI trajectories within each class. Because BMI trajectories differ across different childhood maltreatment experiences-and substantial variability in BMI trajectories exists within these different experiences-future analyses should investigate mediators and moderators of this relationship to inform trauma-based therapies and interventions.

Associations Between Perceived Threats and Firearm Behaviors Among U.S. Adults.

INTRODUCTION: The number of U.S. adults who own and carry a firearm for self-defense is rising. Research has established that owning or carrying a firearm increases the risk of injury and death for firearm owners and the people in their lives. This study sought to better understand this paradox by estimating associations of perceived specific and diffuse threats with firearm behaviors among U.S. adults. METHODS: The authors used data from the 2023 National Firearm Attitudes and Behaviors Study, a nationally representative cross-sectional survey of U.S. adults. Binary and ordinal logistic regression estimated associations of perceived specific (fear of attack in the community, fear of someone breaking into the home) and diffuse threats (belief in a dangerous world) with firearm ownership and carriage frequency, overall and stratified by gender. Adjusted models controlled for violence exposures and demographic characteristics. The authors conducted analyses in 2024. RESULTS: Among all U.S. adults, the perceived specific threat of someone breaking into the home was associated with firearm ownership (AOR: 1.09 [0.98, 1.23]). Among firearm-owning adults, the diffuse threat of belief in a dangerous world was associated with firearm carriage frequency (1.11 [0.98, 1.25]). Both the associations persisted among men (AORs = 1.27 [1.05-1.52] and 1.15 [1.01-1.31], respectively), but analyses found no associations between perceived threats and firearm behaviors among women. CONCLUSIONS: Perceived threats are associated with firearm behaviors among U.S. men, even after accounting for the actual violence they report experiencing or witnessing.

Firearm suicide risk beliefs and prevention: The role of fear of community violence and firearm ownership for protection.

INTRODUCTION: Household firearm availability is a risk factor for firearm suicide when a household member at-risk for suicide. Firearm ownership for protection and perceptions of community violence may reduce the likelihood of limiting access to firearms as a way to prevent suicide. The association between a firearm suicide risk belief and the intention to reduce firearm access as a means of preventing suicide, with fear of community violence and firearm ownership for protection as moderators, was examined. MATERIALS AND METHODS: The analytic sample consisted of 388 Missouri firearm owners from a cross-sectional, statewide survey of Missouri adults. Logistic regression models were estimated. RESULTS: Among Missouri firearm owners, firearm suicide risk belief was positively associated with the intention of reducing firearm access for firearm owners who were not afraid of community violence and owned a firearm for non-protection reasons (e.g., hunting). DISCUSSION: Findings suggest that firearm suicide prevention efforts must be tailored to address the underlying beliefs about their violence risk among firearm owners who indicate they principally own for protection.

Complex, Co-occurring Needs Patterns and Evidence-Based Service Planning for Families Involved in Foster Care: A Map for Research and Practice.

This study described the complexity of service need co-occurrence among foster care-involved families and identified prevalent patterns of needs to inform future evidence-based service planning research. We utilized state administrative child maltreatment records, and restricted data to cases where the child entered foster care in 2019 and the caseworker indicated the presence of at least one need from the Family Assessment of Needs and Strengths (FANS; n = 1631). We extracted all unique combinations of needs (i.e., needs profiles), and we used association rule mining to identify patterns within these profiles. A total of 780 unique needs profiles emerged among the 1631 cases, which we condensed into 78 patterns. Although the variability and complexity of needs profiles makes evidence-based service planning difficult, the present analysis mapped prevalent needs patterns to guide future research intended to assist caseworkers in this task. Identification of maltreatment determinants among families involved in foster care, and future research into the needs within different needs patterns that might undermine treatment effectiveness, may result in a better balance between parsimonious service plans and a full consideration of co-occurring service needs.

Firearms Availability Among High-School Age Youth With Recent Depression or Suicidality.

BACKGROUND AND OBJECTIVES: Limiting firearm access is essential to decreasing teen suicide. Previous efforts have focused on household firearms; however, less is known about firearm access and possession among teens at increased suicide risk. Our objective was to estimate prevalence of firearm possession and access among high school-aged teens with recent depression and/or lifetime history of suicidality (DLHS). METHODS: We conducted a probability-based, cross-sectional Web survey of 1914 parent-teen dyads between June 24, 2020, and July 22, 2020, with data weighted to generate a nationally representative sample of US teenagers (aged 14-18). Logistic regression analyses examined the difference between teens with and without DLHS for: (1) personal firearm possession, (2) perceived firearm access, and (3) method of firearm attainment. RESULTS: Among high school-aged teens, 22.6% (95% confidence interval [CI], 19.4-25.8) reported DLHS, 11.5% (95% CI, 8.7-14.3) reported personal firearm possession, and 44.2% (95% CI, 40.2-48.2) endorsed firearm access. Teens experiencing DLHS had increased perceived access (adjusted odds ratio, 1.56; 95% CI, 1.07-2.28) compared with non-DLHS peers. There was no association between DLHS and personal firearm possession (adjusted odds ratio, 0.97; 95% CI, 0.47-2.00). Among teens reporting firearm possession, those with DLHS were more likely to have acquired it by buying/trading for it (odds ratio, 5.66; 95% CI, 1.17-27.37) and less likely receiving it as a gift (odds ratio, 0.06; 95% CI, 0.01-0.36). CONCLUSIONS: High school-aged teens experiencing DLHS have higher perceived firearm access compared with lower-risk peers. Providers should speak directly to high school-aged teens at increased suicide risk about firearm access, in addition to counseling parents.

Medicaid expansion and postpartum depressive symptoms: evidence from the 2009-2018 Pregnancy Risk Assessment Monitoring System survey.

PURPOSE: This population-representative study examined the association of Medicaid expansion under the Patient Protection and Affordable Care Act (ACA) with postpartum depressive symptoms among low-income women. METHODS: We used data from the 2009 - 2018 Pregnancy Risk Assessment Monitoring System (PRAMS) surveys for 13 Medicaid expansion and 7 non-expansion states. We used a generalized difference-in-differences approach and log-binomial regression models to calculate prevalence ratios (PRs) and 95% confidence intervals (CIs) comparing the likelihood of postpartum depressive symptoms among low-income women (≤138% of the federal poverty level) who delivered in expansion and non-expansion states. RESULTS: Adjusting for state and year fixed-effects and individual- and state-level confounders, low-income women who delivered in Medicaid expansion states had a decreased likelihood of postpartum depressive symptoms compared to low-income women who delivered in non-expansion states (PR = 0.93, 95% CI 0.80, 1.07). Results were largely consistent across multiple sensitivity analysis specifications. Results were robust to falsification tests among women with incomes >138% of the federal poverty level. CONCLUSION: Our results indicate that Medicaid expansion may be associated with a small reduction in the likelihood of postpartum depressive symptoms. Future research should examine the potential for implementation of multiple supportive policies to achieve larger gains in treatment and prevention.

A text-based approach to measuring opioid-related risk among families involved in the child welfare system.

BACKGROUND: The public health significance of the opioid epidemic is well-established. However, few states collect data on opioid problems among families involved in child welfare services. The absence of data creates significant barriers to understanding the impact of opioids on the service system and the needs of families being served. OBJECTIVE: This study sought to validate binary and count-based indicators of opioid-related maltreatment risk based on mentions of opioid use in written child welfare summaries. DATA AND PROCEDURES: We developed a comprehensive list of terms referring to opioid street drugs and pharmaceuticals. This terminology list was used to scan and flag investigator summaries from an extensive collection of investigations (N = 362,754) obtained from a state-based child welfare system in the United States. Associations between mentions of opioid use and investigators' decisions to substantiate maltreatment and remove a child from home were tested within a framework of a priori hypotheses. RESULTS: Approximately 6.3% of all investigations contained one or more opioid use mentions. Opioid mentions exhibited practically signficant associations with investigator decisions. One in ten summaries that were substantiated had an opioid mention. One in five investigations that led to the out-of-home placement of a child contained an opioid mention. CONCLUSION: This study demonstrates the feasibility of using simple text mining procedures to extract information from unstructured text documents. These methods provide novel opportunities to build insights into opioid-related problems among families involved in a child welfare system when structured data are not available.

Social Determinants of Severe Injury Among Pediatric Patients During the COVID-19 Pandemic: An Exploratory Study.

INTRODUCTION: This study sought to identify social determinants of health (SDH) patterns associated with severe pediatric injuries. METHOD: We used cross-sectional data from children (≤18 years) admitted to a pediatric trauma center between March and November 2021 (n = 360). We used association rule mining (ARM) to explore SDH patterns associated with severe injury. We then used ARM-identified SDH patterns in multivariable logistic regressions of severe injury, controlling for patient and caregiver demographics. Finally, we compared results to naive hierarchical logistic regressions that considered SDH types as primary exposures rather than SDH patterns. RESULTS: We identified three SDH patterns associated with severe injury: (1) having child care needs in combination with neighborhood violence, (2) caregiver lacking health insurance, and (3) caregiver lacking social support. In the ARM-informed logistic regression models, the presence of a child care need in combination with neighborhood violence was associated with an increased odds of severe injury (aOR, 2.77; 95% CI, 1.01-7.62), as was caregiver lacking health insurance (aOR, 2.29; 95% CI, 1.02-5.16). In the naive hierarchical logistic regressions, no SDH type in isolation was associated with severe injury. DISCUSSION: Our exploratory analyses suggest that considering the co-occurrence of negative SDH that families experience rather than isolated SDH may provide greater insights into prevention strategies for severe pediatric injury.
