Metabolic Dysfunction-Associated Fibrosis 5 (MAF-5) Score Predicts Liver Fibrosis Risk and Outcome in the General Population With Metabolic Dysfunction.

BACKGROUND & AIMS: There is an unmet need for noninvasive tests to improve case-finding and aid primary care professionals in referring patients at high risk of liver disease. METHODS: A metabolic dysfunction-associated fibrosis (MAF-5) score was developed and externally validated in a total of 21,797 individuals with metabolic dysfunction in population-based (National Health and Nutrition Examination Survey 2017-2020, National Health and Nutrition Examination Survey III, and Rotterdam Study) and hospital-based (from Antwerp and Bogota) cohorts. Fibrosis was defined as liver stiffness ≥8.0 kPa. Diagnostic accuracy was compared with FIB-4, nonalcoholic fatty liver disease fibrosis score (NFS), LiverRisk score and steatosis-associated fibrosis estimator (SAFE). MAF-5 was externally validated with liver stiffness measurement ≥8.0 kPa, with shear-wave elastography ≥7.5 kPa, and biopsy-proven steatotic liver disease according to Metavir and Nonalcoholic Steatohepatitis Clinical Research Network scores, and was tested for prognostic performance (all-cause mortality). RESULTS: The MAF-5 score comprised waist circumference, body mass index (calculated as kg / m2), diabetes, aspartate aminotransferase, and platelets. With this score, 60.9% was predicted at low, 14.1% at intermediate, and 24.9% at high risk of fibrosis. The observed prevalence was 3.3%, 7.9%, and 28.1%, respectively. The area under the receiver operator curve of MAF-5 (0.81) was significantly higher than FIB-4 (0.61), and outperformed the FIB-4 among young people (negative predictive value [NPV], 99%; area under the curve [AUC], 0.86 vs NPV, 94%; AUC, 0.51) and older adults (NPV, 94%; AUC, 0.75 vs NPV, 88%; AUC, 0.55). MAF-5 showed excellent performance to detect liver stiffness measurement ≥12 kPa (AUC, 0.86 training; AUC, 0.85 validation) and good performance in detecting liver stiffness and biopsy-proven liver fibrosis among the external validation cohorts. MAF-5 score >1 was associated with increased risk of all-cause mortality in (un)adjusted models (adjusted hazard ratio, 1.59; 95% CI, 1.47-1.73). CONCLUSIONS: The MAF-5 score is a validated, age-independent, inexpensive referral tool to identify individuals at high risk of liver fibrosis and all-cause mortality in primary care populations, using simple variables.

Stronger together than apart: The role of social support in adopting a healthy plant-based eating pattern.

The influence of the social environment on health behaviors is well documented. In recent years, there is mounting evidence of the health benefits of a plant-based eating pattern, yet little is known about how the social environment impacts the adoption of a plant-based eating pattern, specifically. In this convergent parallel mixed-methods study, we analyzed quantitative survey data and qualitative focus group data to assess how social support impacted participants of a lifestyle medicine intervention focused on the adoption of a plant-predominant eating pattern. Regression analysis of survey data showed a positive association between positive social support and healthy plant-based eating, while no association was found between negative social support and healthy plant-based eating. Focus groups yielded further insights into how positive aspects of social relationships with family and friends facilitated the adoption of plant-predominant eating among participants. Qualitative findings also showed the ways in which negative social support hindered progress to adopt a plant-predominant eating pattern including not eating the same foods as participants, being judgmental about new dietary behaviors, and encouraging participants to eat non-plant-based foods. Taken together, social support appears to be an important factor for individuals adopting a plant-predominant eating pattern. Future research is needed to explore mechanisms to enhance positive social support while mitigating negative aspects of social relationships for individuals participating in similar lifestyle medicine interventions that emphasize on plant-predominant eating.

Prenatal oxidative stress and rapid infant weight gain.

BACKGROUND AND OBJECTIVES: Infant weight patterns predict subsequent weight outcomes. Rapid infant weight gain, defined as a >0.67 increase in weight-for-age z-score (WAZ) between two time points in infancy, increases obesity risk. Higher oxidative stress, an imbalance between antioxidants and reactive oxygen species, has been associated with low birthweight and paradoxically also with later obesity. We hypothesized that prenatal oxidative stress may also be associated with rapid infant weight gain, an early weight pattern associated with future obesity. METHODS: Within the NYU Children's Health and Environment Study prospective pregnancy cohort, we analyzed associations between prenatal lipid, protein, and DNA urinary oxidative stress biomarkers and infant weight data. Primary outcome was rapid infant weight gain (>0.67 increase in WAZ) between birth and later infancy at the 8 or 12 month visit. Secondary outcomes included: very rapid weight gain (>1.34 increase in WAZ), low (<2500 g) or high (≥4000 g) birthweight, and low (< -1 WAZ) or high (>1 WAZ) 12 month weight. RESULTS: Pregnant participants consented to the postnatal study (n = 541); 425 participants had weight data both at birth and in later infancy. In an adjusted binary model, prenatal 8-iso-PGF2α, a lipid oxidative stress biomarker, was associated with rapid infant weight gain (aOR 1.44; 95% CI: 1.16, 1.78, p = 0.001). In a multinomial model using ≤0.67 change in WAZ as a reference group, 8-iso-PGF2α was associated with rapid infant weight gain (defined as >0.67 but ≤1.34 WAZ; aOR 1.57, 95% CI: 1.19, 2.05, p = 0.001) and very rapid infant weight gain (defined as >1.34 WAZ; aOR 1.33; 95% CI: 1.02, 1.72, p < 0.05) Secondary analyses detected associations between 8-iso-PGF2α and low birthweight outcomes. CONCLUSIONS: We found an association between 8-iso-PGF2α, a lipid prenatal oxidative stress biomarker, and rapid infant weight gain, expanding our understanding of the developmental origins of obesity and cardiometabolic disease.

Impact of the COVID-19 pandemic on digestive endoscopists: an Ibero-American study.

INTRODUCTION: the COVID-19 pandemic has seriously affected the world population, and has put health personnel in the spotlight as they are tasked with its management. Given their important role in the current health crisis, physicians have been heavily affected in terms of their professional practice, financial conditions and physical and mental health. The objective of this study was to determine the consequences of the COVID-19 pandemic for Colombian endoscopists and compare the effects on endoscopists from South America and from Spain. METHODS: in June 2021, an electronic survey was sent to 292 endoscopists from Colombia, South America and Spain to determine the impact of the pandemic on their professional practice, economic situation, physical and mental health, and training of the residents under their charge. Participants were recruited via convenience sampling. RESULTS: a reduction in the number of endoscopic procedures was reported by 69.9 % of the respondents, and 72.3 % of endoscopists in Colombia stated that their income had decreased. Regarding the doctor-patient relationship, 43.8 % of the respondents believed it had worsened. In addition, 70.9 % reported having experienced changes in their emotional state, especially those related to feeling sad or depressed, and 56.5 % reported that the pandemic had negatively affected the training of residents. Finally, 24.7 % of endoscopists tested positive for COVID-19, and 19.2 % reported the death of a family member due to COVID-19. CONCLUSION: the COVID-19 pandemic has had a negative impact on the professional practice, financial situation and physical and mental health of Ibero-American endoscopists. These problems must be identified in a timely manner to develop and implement strategies aimed to prevent their occurrence.

Comparison of shear wave elastography (supersonic) with liver biopsy in a cohort of patients from a medium-income country: an observational study.

INTRODUCTION: shear-wave elastography is a non-invasive diagnostic test that calculates the degree of liver fibrosis by measuring liver elasticity. This technique was recently introduced in Colombia. Thus, cutoff points delineating the change between fibrosis stages (using the Metavir scale) have not been previously defined in our patient population. PATIENTS AND METHODS: a retrospective study was performed of patients who had undergone two-dimensional shear-wave elastography (2D-SWE) and liver biopsy (LB) between June 2010 and June 2018 at a private outpatient hepatology center in Bogota, Colombia. We used a training dataset (subjects with time between biopsy and 2D-SWE of ≤ 6 months) to establish diagnostic cutoff values and a test dataset (subjects with time between biopsy and 2D-SWE of > 6 months) to validate our results. RESULTS: a total of 453 subjects (training dataset, n = 153; test dataset, n = 300) were included. In the training dataset, the cutoff points were 7.6, 8.4, 9.5 and 10.9 kPa, and the areas under the curve were 0.75, 0.83, 0.89 and 0.94 for mild fibrosis, significant fibrosis, advanced fibrosis and cirrhosis, respectively. In the test dataset, the areas under the curve were 0.77, 0.78, 0.83 and 0.89 for mild fibrosis, significant fibrosis, advanced fibrosis, and cirrhosis, respectively. CONCLUSION: two-dimensional shear-wave elastography was reliable and useful for the non-invasive evaluation of liver fibrosis, particularly in patients with advanced fibrosis and cirrhosis. Cutoff points for fibrosis in a Hispanic population were described.

Quantifying the influence of child abuse history on the cardinal symptoms of fibromyalgia.

OBJECTIVES: To quantify the influence of abuse, particularly in childhood, with pain sensitivity and other adverse symptoms experienced by women with fibromyalgia (FM). METHODS: Subjects with FM completed a detailed abuse interview, dolorimetry, and questionnaire-based assessments of fatigue, cognitive self-appraisal, and depression. Student's t- and chi-square tests were used to analyse differences in FM symptoms between those with and without a history of childhood abuse. Linear regression was used to evaluate the relationship between abuse and symptom severity, adjusting for possible confounders. RESULTS: In 111 women with FM, physical abuse during childhood demonstrated a clinically modest, yet statistically significant, association with increased tenderness as measured by pain pressure thresholds (ß=-0.25, p=0.011) and tender points (ß=0.23, p=.022). Physical child abuse was also associated with cognitive language impairment after adjusting for depression (ß=0.27, p=0.001). While emotional child abuse was associated with fatigue, the association did not persist after adjustment for depressive symptoms. CONCLUSIONS: Group differences are of small magnitude and might not directly impact clinical practice, however, the experience of child abuse is associated with FM symptom severity and may shape the biological development of interoception in ways that predispose to pain and polysymptomatic distress.

Feasibility, Acceptability, and Health Outcomes Associated With Telehealth for Children in Families With Limited English Proficiency.

BACKGROUND: Telehealth use in pediatrics increased during the COVID-19 pandemic and may improve health care access. It may also exacerbate health care disparities among families with limited English proficiency (LEP). OBJECTIVE: To systematically review the feasibility, acceptability, and/or associations between telehealth delivery and health outcomes for interventions delivered synchronously in the United States. DATA SOURCES: PubMed, Embase, and Scopus. STUDY ELIGIBILITY CRITERIA: Original research exploring pediatric health outcomes after telehealth delivery and studies that explored the feasibility and acceptability including surveys and qualitative studies. PARTICIPANTS: Patients 0 to 18 years with LEP and/or pediatric caregivers with LEP. STUDY APPRAISAL AND SYNTHESIS METHODS: Two authors independently screened abstracts, conducted full-text review, extracted information using a standardized form, and assessed study quality. A third author resolved disagreements. RESULTS: Of 1831 articles identified, 9 were included in the review. Half of the studies explored videoconferencing and the other half studied health care delivered by telephone. Feasibility studies explored telehealth for children with anxiety disorders and mobile phone support for substance abuse treatment among adolescents. Acceptability studies assessed parental medical advice-seeking behaviors and caregivers' general interest in telehealth. Health outcomes studied included follow-up of home parenteral nutrition, developmental screening, and cognitive behavioral therapy. LIMITATIONS: The articles were heterogeneous in approach and quality. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Telehealth appears acceptable and feasible among children in families with LEP, with a limited evidence base for specific health outcomes. We provide recommendations both for the implementation of pediatric telehealth and future research. PROSPERO REGISTRATION: CRD42020204541.

Parent Education and Adolescent Health Outcomes: The Potential Role of Adolescent Academic Intention.

Parental educational attainment significantly shapes child socioeconomic status, potentially influencing various aspects of adolescent health. This study aimed to uncover the relationships between parental education and self-reported adolescent health outcomes, including overall health, mental well-being, and body mass index (BMI). Analyzing data from 1,448 participants in the Future of Families and Child Wellbeing Study, we identified notable associations. Our findings revealed that higher maternal and paternal education correlated with reduced odds of adolescent obesity. Furthermore, increased adolescent academic intention was associated with better overall and mental health in adolescents. Notably, it also played a mediating role in lowering adolescent BMI, thereby potentially explaining the association between parent education and adolescent BMI category (overweight vs. obese). These findings emphasize the significant impact of both parent education and adolescent academic intention on adolescent health. Future research should explore interventions leveraging academic intention to positively influence the health trajectory of adolescents.

Household Food Insecurity and Maternal-Toddler Fruit and Vegetable Dietary Concordance.

OBJECTIVE: To examine whether prenatal or concurrent household food insecurity influences associations between maternal and toddler fruit and vegetable (FV) intake. DESIGN: Application of a life-course framework to an analysis of a longitudinal dataset. SETTING: Early childhood obesity prevention program at a New York City public hospital. PARTICIPANTS: One-hundred and fifty-six maternal-toddler dyads self-identifying as Hispanic or Latino. VARIABLES MEASURED: Maternal and toddler FV intake was measured using Centers for Disease Control and Prevention dietary measures when toddlers were aged 19 months. Household food insecurity (measured prenatally and concurrently at 19 months) was measured using the US Department of Agriculture Food Security Module. ANALYSIS: Regression analyses assessed associations between adequate maternal FV intake and toddler FV intake. Interaction terms tested whether prenatal or concurrent household food insecurity moderated this association. RESULTS: Adequate maternal FV intake was associated with increased toddler FV intake (B = 6.2 times/wk, 95% confidence interval, 2.0-10.5, P = 0.004). Prenatal household food insecurity was associated with decreased toddler FV intake (B = -6.3 times/wk, 95% confidence interval, -11.67 to -0.9, P = 0.02). There was a significant interaction between the level of maternal-toddler FV association (concordance or similarity in FV intake between mothers and toddlers) and the presence of food insecurity such that maternal-toddler FV association was greater when prenatal household food insecurity was not present (B = -11.6, P = 0.04). CONCLUSIONS AND IMPLICATIONS: Strategies to increase FV intake across the life course could examine how the timing of household food insecurity may affect intergenerational maternal-child transmission of dietary practices.

Preterm Birth Risk and Maternal Nativity, Ethnicity, and Race.

Importance: Immigrant birthing people have lower rates of preterm birth compared with their US-born counterparts. This advantage and associated racial and ethnic disparities across the gestational age spectrum have not been examined nationally. Objective: To examine associations of maternal nativity, ethnicity, and race with preterm birth. Design, Setting, and Participants: This cohort study used birth certificates from the National Vital Statistics System to analyze in-hospital liveborn singleton births in the US between January 1, 2009, and December 31, 2018. Data were analyzed from January to June 2023. Exposure: Mutually exclusive nativity, ethnicity, and race subgroups were constructed using nativity (defined as US-born or non-US-born), ethnicity (defined as Hispanic or non-Hispanic), and race (defined as American Indian or Alaska Native, Asian, Black, Native Hawaiian or Other Pacific Islander, White, or other [individuals who selected other race or more than 1 race]). Main Outcomes and Measures: The primary outcome of interest was preterm birth. Modified Poisson and multinomial logistic regression models quantified relative risk (RR) of preterm birth overall (<37 weeks' gestation) and by gestational category (late preterm: 34-36 weeks' gestation; moderately preterm: 29-33 weeks' gestation; and extremely preterm: <29 weeks' gestation) for each maternal nativity, ethnicity, and race subgroup compared with the largest group, US-born non-Hispanic White (hereafter, White) birthing people. The RR of preterm birth overall and by category was also measured within each racial and ethnic group by nativity. Models were adjusted for maternal demographic and medical covariates, birth year, and birth state. Results: A total of 34 468 901 singleton live births of birthing people were analyzed, with a mean (SD) age at delivery of 28 (6) years. All nativity, ethnicity, and race subgroups had an increased adjusted risk of preterm birth compared with US-born White birthing people except for non-US-born White (adjusted RR, 0.85; 95% CI, 0.84-0.86) and Hispanic (adjusted RR, 0.98; 95% CI, 0.97-0.98) birthing people. All racially and ethnically minoritized groups had increased adjusted risks of extremely preterm birth compared with US-born White birthing people. Non-US-born individuals had a decreased risk of preterm birth within each subgroup except non-Hispanic Native Hawaiian or Other Pacific Islander individuals, in which immigrants had significantly increased risk of overall (adjusted RR, 1.07; 95% CI, 1.01-1.14), moderately (adjusted RR, 1.10; 95% CI, 0.92-1.30), and late (adjusted RR, 1.11; 95% CI, 1.02-1.22) preterm birth than their US-born counterparts. Conclusions and Relevance: Results of this cohort study suggest heterogeneity of preterm birth across maternal nativity, ethnicity, and race and gestational age categories. Understanding these patterns could aid the design of targeted preterm birth interventions and policies, especially for birthing people typically underrepresented in research.

Association of Socioeconomic Status With Life's Essential 8 in the National Health and Nutrition Examination Survey: Effect Modification by Sex.

BACKGROUND: Higher scores for the American Heart Association Life's Essential 8 (LE8) metrics, blood pressure, cholesterol, glucose, body mass index, physical activity, smoking, sleep, and diet, are associated with lower risk of chronic disease. Socioeconomic status (SES; employment, insurance, education, and income) is associated with LE8 scores, but there is limited understanding of potential differences by sex. This analysis quantifies the association of SES with LE8 for each sex, within Hispanic Americans, non-Hispanic Asian Americans, non-Hispanic Black Americans, and non-Hispanic White Americans. METHODS AND RESULTS: Using cross-sectional data from the National Health and Nutrition Examination Survey, years 2011 to 2018, LE8 scores were calculated (range, 0-100). Age-adjusted linear regression quantified the association of SES with LE8 score. The interaction of sex with SES in the association with LE8 score was assessed in each racial and ethnic group. The US population representatively weighted sample (13 529 observations) was aged ≥20 years (median, 48 years). The association of education and income with LE8 scores was higher in women compared with men for non-Hispanic Black Americans and non-Hispanic White Americans (P for all interactions <0.05). Among non-Hispanic Asian Americans and Hispanic Americans, the association of SES with LE8 was not different between men and women, and women had greater LE8 scores than men at all SES levels (eg, high school or less, some college, and college degree or more). CONCLUSIONS: The factors that explain the sex differences among non-Hispanic Black Americans and non-Hispanic White Americans, but not non-Hispanic Asian Americans and Hispanic Americans, are critical areas for further research to advance cardiovascular health equity.

Evidence for the Association Between Adverse Childhood Family Environment, Child Abuse, and Caregiver Warmth and Cardiovascular Health Across the Lifespan: The Coronary Artery Risk Development in Young Adults (CARDIA) Study.

BACKGROUND: This study aimed to quantify the association between childhood family environment and longitudinal cardiovascular health (CVH) in adult CARDIA (Coronary Artery Risk Development in Young Adults) Study participants. We further investigated whether the association differs by adult income. METHODS: We applied the CVH framework from the American Heart Association including metrics for smoking, cholesterol, blood pressure, glucose, body mass index, physical activity, and diet. CVH scores (range, 0-14) were calculated at years 0, 7, and 20 of the study. Risky Family environment (range, 7-28) was assessed at year 15 retrospectively, for childhood experiences of abuse, caregiver warmth, and family or household challenges. Complete case ordinal logistic regression and mixed models associated risky family (exposure) with CVH (outcome), adjusting for age, sex, race, and alcohol use. RESULTS: The sample (n=2074) had a mean age of 25.3 (±3.5) years and 56% females at baseline. The median risky family was 10 with ideal CVH (≥12) met by 288 individuals at baseline (28.4%) and 165 (16.3%) at year 20. Longitudinally, for every 1-unit greater risky family, the odds of attaining high CVH (≥10) decreased by 3.6% (OR, 0.9645 [95% CI, 0.94-0.98]). Each unit greater child abuse and caregiver warmth score corresponded to 12.8% lower and 11.7% higher odds of ideal CVH (≥10), respectively (OR, 0.872 [95% CI, 0.77-0.99]; OR, 1.1165 [95% CI, 1.01-1.24]), across all 20 years of follow-up. Stratified analyses by income in adulthood demonstrated associations between risky family environment and CVH remained significant for those of the highest adult income (>$74k), but not the lowest (<$35k). CONCLUSIONS: Although risky family environmental factors in childhood increase the odds of poor longitudinal adult CVH, caregiver warmth may increase the odds of CVH, and socioeconomic attainment in adulthood may contextualize the level of risk. Toward a paradigm of primordial prevention of cardiovascular disease, childhood exposures and economic opportunity may play a crucial role in CVH across the life course.

The Role of the Mind-Body Connection in Children with Food Reactions and Identified Adversity: Implications for Integrating Stress Management and Resilience Strategies in Clinical Practice.

Child adversity is often associated with poor quality of life in pediatric gastrointestinal disorders, including non-allergic food reactions (food intolerances), which may be improved using mind-body interventions. We conducted an observational study to (1) describe child adversity (stressors) and resilience factors in children with food intolerances, and (2) explore the association between stressors and self-reported use of integrative modalities. A retrospective chart review of children ≥4-years-old presenting to a pediatric food intolerances clinic from 2017 to 2020 was performed (n = 130). Use of integrative medicine at intake, demographic, illness, and social history data were collected. Qualitative analysis identified exposure to stressors and resilience strategies. Correlation was assessed using a chi-square test. Management of the medical condition was the most common stressor, indicating impact on quality of life. Resilience strategies included themes of self-coping and social support. Individuals with one or more stressors were more likely to be using an integrative modality (most commonly, mind-body interventions) prior to their visit (X2 = 8.1, p = 0.004). Our hypothesis-generating study suggests that screening for child adversity and integrative medicine use may be used to better address quality of life and personalized approaches to treat pediatric food intolerances.

Supporting early childhood routines to promote cardiovascular health across the life course.

Optimal cardiovascular health is an essential component of human health and well-being across the life course. Heart healthy practices around diet, physical activity, and sleep early in childhood have the potential to greatly improve lifespan and quality (Mehta et al., 2020). Early childhood routines, defined as functional practices that are predictable and repeatable, predict positive growth and development across the lifecourse (Fiese et al., 2002; Ferretti and Bub, 2017; Spagnola and Fiese, 2007). The American Heart Association has identified key heart healthy routines, such as daily regular activities including diet, physical activity, and sleep that promote cardiovascular health (Lloyd-Jones et al., 2022). Integrating the strength-based relational aspects of routines with the acquisition of cardiovascular health development capabilities allows children to establish their own optimal cardiovascular health trajectory early on. A systematic life course approach to supporting heart healthy routines in early childhood would inform clinical, research, and policy strategies to promote long-term cardiovascular health, and contribute to reducing inequalities in cardiovascular outcomes.

Patient-Reported Outcomes from a Pilot Plant-Based Lifestyle Medicine Program in a Safety-Net Setting.

Lifestyle medicine interventions that emphasize healthy behavior changes are growing in popularity in U.S. health systems. Safety-net healthcare settings that serve low-income and uninsured populations most at risk for lifestyle-related disease are ideal venues for lifestyle medicine interventions. Patient-reported outcomes are important indicators of the efficacy of lifestyle medicine interventions. Past research on patient-reported outcomes of lifestyle medicine interventions has occurred outside of traditional healthcare care settings. In this study, we aimed to assess patient-reported outcomes on nutrition knowledge, barriers to adopting a plant-based diet, food and beverage consumption, lifestyle behaviors, self-rated health, and quality-of-life of participants in a pilot plant-based lifestyle medicine program in an urban safety-net healthcare system. We surveyed participants at three time points (baseline, 3 months, 6 months) to measure change over time. After 6 months of participation in the program, nutrition knowledge increased by 7.2 percentage points, participants reported an average of 2.4 fewer barriers to adopting a plant-based diet, the score on a modified healthful plant-based diet index increased by 5.3 points, physical activity increased by 0.7 days per week while hours of media consumption declined by 0.7 h per day, and the percentage of participants who reported that their quality of sleep was "good" or "very good" increased by 12.2 percentage points. Our findings demonstrate that a lifestyle medicine intervention in a safety-net healthcare setting can achieve significant improvements in patient-reported outcomes. Key lessons for other lifestyle medicine interventions include using a multidisciplinary team; addressing all pillars of lifestyle medicine; and the ability for patients to improve knowledge, barriers, skills, and behaviors with adequate support.

Structural racism and health: Assessing the mediating role of community mental distress and health care access in the association between mass incarceration and adverse birth outcomes.

Research has linked spatial concentrations of incarceration with racial disparities in adverse birth outcomes. However, little is known about the specific mechanisms of this association. This represents an important knowledge gap in terms of intervention. We theorize two pathways that may account for the association between county-level prison rates and adverse birth outcomes: (1) community-level mental distress and (2) reduced health care access. Examining these mechanisms, we conducted a cross-sectional study of county-level prison rates, community-level mental distress, health insurance, availability of primary care physicians (PCP) and mental health providers (MHP), and adverse birth outcomes (preterm birth, low birth weight, infant mortality). Our data set included 475 counties and represented 2,677,840 live U.S. births in 2016. Main analyses involved between 170 and 326 counties. All data came from publicly available sources, including the U.S. Census and the Centers for Disease Control and Prevention. Descriptive and regression results confirmed the link between prison rates and adverse birth outcomes and highlighted Black-White inequities in this association. Further, bootstrap mediation analyses indicated that the impact of spatially concentrated prison rates on preterm birth was mediated by PCP, MHP, community-level mental distress, and health insurance in both crude and adjusted models. Community-level mental distress and health insurance (but not PCP or MHP) similarly mediated low birthweight in both models. Mediators were less stable in the effect on infant mortality with only MHP mediating consistently across models. We conclude that mass incarceration, health care access, and community mental distress represent actionable and urgent targets for structural-, community-, and individual-level interventions targeting population inequities in birth outcomes.

Childhood environment early life stress, caregiver warmth, and associations with the cortisol diurnal curve in adulthood: The coronary artery risk development in young adults (CARDIA) study.

BACKGROUND: Early life stress (ELS) is associated with increased morbidity and mortality across the lifecourse. Studies observing a relationship between ELS and stress physiology (cortisol), may help explain the connection to poor health outcomes, but have been limited by cortisol measures used. PURPOSE: We examined the association between ELS measured by a Risky Family (RF) environment questionnaire, and adult diurnal cortisol profile inclusive of multiple cortisol measures. METHODS: RF and cortisol were collected from Coronary Artery Risk Development in Young Adults Study participants at follow-up (Year 15). Complete case (n = 672) data were included in multi-variable regression analyses with log transformed cortisol measures (outcomes) including wake-up cortisol, cortisol awakening response [CAR], AUC and five other cortisol diurnal curve measures. RESULTS: Participants were age 39.9 + /- 3.7 years and 51.6% Black. For every 1 unit increase in RF, there was a 1.4% greater wake-up cortisol and flatter CAR after adjustment for age, sex, income, and smoking (B=0.014, p = 0.023; B=-0.014, p = 0.028, respectively). Each unit increase in caregiver warmth/affection was associated with a 6.9% higher (steeper) CAR (B=0.069, p = 0.03). Results remained significant after adjusting for other covariates except social support in adulthood. An interaction between child abuse and caregiver warmth was nearly significant (p = 0.068), such that for those with exposure to the greatest caregiver warmth and lowest child abuse, CAR was steepest CONCLUSIONS: We demonstrate that ELS is associated with altered cortisol regulation in adulthood. However, further research is needed to assess how healthy relationships throughout the life course may modulate cortisol regulation in adulthood.

County-Level Maternal Vulnerability and Preterm Birth in the US.

Importance: Appreciation for the effects of neighborhood conditions and community factors on perinatal health is increasing. However, community-level indices specific to maternal health and associations with preterm birth (PTB) have not been assessed. Objective: To examine the association of the Maternal Vulnerability Index (MVI), a novel county-level index designed to quantify maternal vulnerability to adverse health outcomes, with PTB. Design, Setting, and Participants: This retrospective cohort study used US Vital Statistics data from January 1 to December 31, 2018. Participants included 3 659 099 singleton births at 22 plus 0/7 to 44 plus 6/7 weeks of gestation born in the US. Analyses were conducted from December 1, 2021, through March 31, 2023. Exposure: The MVI, a composite measure of 43 area-level indicators, categorized into 6 themes reflecting physical, social, and health care landscapes. Overall MVI and theme were stratified by quintile (very low to very high) by maternal county of residence. Main Outcomes and Measures: The primary outcome was PTB (gestational age <37 weeks). Secondary outcomes were PTB categories: extreme (gestational age ≤28 weeks), very (gestational age 29-31 weeks), moderate (gestational age 32-33 weeks), and late (gestational age 34-36 weeks). Multivariable logistic regression quantified associations of MVI, overall and by theme, with PTB, overall and by PTB category. Results: Among 3 659 099 births, 298 847 (8.2%) were preterm (male, 51.1%; female, 48.9%). Maternal race and ethnicity included 0.8% American Indian or Alaska Native, 6.8% Asian or Pacific Islander, 23.6% Hispanic, 14.5% non-Hispanic Black, 52.1% non-Hispanic White, and 2.2% with more than 1 race. Compared with full-term births, MVI was higher for PTBs across all themes. Very high MVI was associated with increased PTB in unadjusted (odds ratio [OR], 1.50 [95% CI, 1.45-1.56]) and adjusted (OR, 1.07 [95% CI, 1.01-1.13]) analyses. In adjusted analyses of PTB categories, MVI had the largest association with extreme PTB (adjusted OR, 1.18 [95% CI, 1.07-1.29]). Higher MVI in the themes of physical health, mental health and substance abuse, and general health care remained associated with PTB overall in adjusted models. While the physical health and socioeconomic determinant themes were associated with extreme PTB, physical health, mental health and substance abuse, and general health care themes were associated with late PTB. Conclusions and Relevance: The findings of this cohort study suggest that MVI was associated with PTB even after adjustment for individual-level confounders. The MVI is a useful measure for county-level PTB risk that may have policy implications for counties working to lower preterm rates and improve perinatal outcomes.

A comprehensive framework for operationalizing structural racism in health research: The association between mass incarceration of Black people in the U.S. and adverse birth outcomes.

Structural racism represents a key determinant of the racial health disparities that has characterized the U.S. population throughout its existence. While this reality has recently begun to gain increasing acknowledgment and acceptance within the health sciences, there are still considerable challenges related to defining the concept of structural racism and operationalizing it in empirical study. In this paper, building on the existing evidence base, we propose a comprehensive framework that centers structural racism in terms of its historical roots and continued manifestation in most domains of society, and offer solutions for the study of this phenomenon and the pathways that connect it to population-level health disparities. We showcase our framework by applying it to the known link between spatial and racialized clustering of incarceration - a previously cited representation of structural racism - and disparities in adverse birth outcomes. Through this process we hypothesize pathways that focus on social cohesion and community-level chronic stress, community crime and police victimization, as well as infrastructural community disinvestment. First, we contextualize these mechanisms within the relevant extant literature. Then, we make recommendations for future empirical pathway analyses. Finally, we identify key areas for policy, community, and individual-level interventions that target the impact of concentrated incarceration on birth outcomes among Black people in the U.S.

"The Stay at Home Order is Causing Things to Get Heated Up": Family Conflict Dynamics During COVID-19 From The Perspectives of Youth Calling a National Child Abuse Hotline.

The purpose of this study was to identify changes in family conflict and abuse dynamics during COVID-19 stay-at-home orders from the perspectives of youth calling a national child abuse hotline. We analyzed text and chat transcripts from Childhelp's National Child Abuse Hotline from May-June 2020 that were flagged as coming from a child with a COVID-19-related concern (N = 105). Thematic analysis was used to identify COVID-19 related influences of family conflict as well as how COVID-19 constraints influenced coping and survival for youth reporting distress or maltreatment to the hotline. Family conflict most commonly disclosed stemmed from parental or child mental health concerns, often manifesting in escalated child risk taking behaviors, parental substance use, and violence in the home. Conflict was also mentioned surrounding caregiver issues with child productivity while sheltering-in-place, commonly related to school or chores. Youth often voiced feeling unable to find relief from family conflict, exacerbated from physical distance from alternative social supports, technological isolation, and limited contact with typical safe places or supportive adults. To cope and survive, youth and crisis counselors found creative home-based coping skills and alternative reporting mechanisms. Understanding the unique impact of COVID-19 on youth in homes with family conflict and abuse can point to areas for intervention to ensure we are protecting the most vulnerable as many continue to shelter-in-place. In particular, this study revealed the importance of online hotlines and reporting mechanisms to allow more youth to seek out the help and professional support they need.
