Abstract
INTRODUCTION Firearms are now the number one killer of children and adolescents in the United States. Firearm homicides among Black male youth are the driver of this increase. Prevention requires a multi-faceted life course approach. Academic achievement has been identified as a protective factor. Early childhood education, which is linked to later achievement, is thus an intervention area of interest. Conceptualizing the potential links between early childhood education and reduced risk for youth firearm homicide is important for guiding policy advocacy and informing future research. METHODS This paper presents a conceptual model linking early childhood education to reduced risk for firearm homicide. Each link in the model is discussed, and a corresponding review of the literature is presented. The need for anti-racist policies to strengthen the impact of early childhood education is highlighted. RESULTS Early education and firearm homicide research are each well-established but largely disconnected. There are clear immediate benefits of early childhood education; however, these effects wane with time, particularly for youth of color. At the same time, juvenile delinquency-a major risk factor for firearm homicide-is influenced by educational inequities. CONCLUSIONS Effective interventions to reduce firearm homicides among Black male youth in the United States are needed. Early childhood education shows promise as an intervention. However, to have an impact, this education needs to be accessible and affordable for all, particularly families of color and low income. Societal structures and policies must also better support the positive gains seen through early childhood education to avoid dissipation.

Abstract
BACKGROUND Life course factors may be associated with pre-pregnancy body mass index and gestational weight gain; however, collecting information on pre-pregnancy exposures and pregnancy health in the same cohort is challenging. OBJECTIVES The Life-course Experiences And Pregnancy (LEAP) study aims to identify adolescent and young adult risk factors for pre-pregnancy weight and gestational weight gain (GWG). We built upon an existing cohort study to overcome challenges inherent to studying life course determinants of pregnancy health. POPULATION Participants in an ongoing prospective cohort study of weight-related health who identified as women. DESIGN Retrospective cohort study. METHODS In 2019-2020, 1,252 women participating since adolescence in a cohort study of weight-related health were invited to complete an online reproductive history survey. Participants who reported a live birth were invited to release their prenatal, delivery, and postpartum medical records for validation of survey reports. Descriptive analyses were conducted to assess the characteristics of the overall cohort and the medical record validation subsample, and to describe adolescent and young adult characteristics of those with high (>80th percentile), moderate (20th-80th percentile), and low (<20th percentile) GWG z-score for gestational age and pre-pregnancy weight status. PRELIMINARY RESULTS Nine hundred seventy-seven women (78%) completed the LEAP survey and 656 reported a live birth. Of these, 379 (58%) agreed to release medical records, and 250 records were abstracted (66% of the 379). Of the 977 survey respondents 769 (79%) reported attempting a pregnancy, and 656 (67%) reported at least one live birth. The validation subsample was similar to the overall cohort. Women with a high GWG had a higher adolescent BMI percentile and prevalence of unhealthy weight control behaviors than those with moderate or low GWG. CONCLUSIONS LEAP offers a valuable resource for identifying life course factors that may influence the health of pregnant people and their offspring.

Abstract
BACKGROUND Growing evidence on the long-term deleterious impacts of emotional abuse highlights the need to further understand childhood emotional abuse and its context to strengthen prevention efforts. OBJECTIVE To describe emerging adults' experiences of emotional abuse in their childhoods and the household context surrounding that abuse. PARTICIPANTS AND SETTING Fifty-eight interviews were conducted with emerging adults, ages 18-25, recruited from four 2- and 4-year institutions of higher education. METHODS Thematic analysis was conducted to identify and describe patterns in the data. A cyclical approach to codebook development and data analysis was followed by a team of four coders. RESULTS Themes related to participants' experiences of emotional abuse included: inability to meet parent expectations; parent attacks on the child's character; parent negative comparisons to siblings and others; parent invalidation of the child's emotions and mental health needs; and evolution over time in the parent-child relationship. Aspects of childhood family environments contemporaneous with the childhood emotional abuse included: financial stress; parent mental illness; parent divorce, separation, or volatile relationship; parent adversity or trauma; physical abuse; and young parent age. Many participants identified these aspects of their family environment, most of which could potentially be improved with sufficient support, as playing causal roles in the emotional abuse they experienced. CONCLUSION This descriptive qualitative study provides additional insight into child emotional abuse and its associated factors, providing invaluable insights that can enhance current measurement and intervention approaches.

Abstract
OBJECTIVE Low childhood socio-economic status (SES) and adverse childhood experiences (ACE) are associated with poor health outcomes in adulthood. Determining how ACE may be linked to food insecurity among young people from socio-economically diverse households can inform health-protective strategies. This study examined if ACE are associated with food insecurity during the transition to adulthood and investigated prevalence differences across SES strata. SETTING Participants were recruited from twenty secondary schools in Minneapolis-St. Paul, Minnesota. PARTICIPANTS The analytic sample (n 1518) completed classroom surveys in 2009-2010 (mean age = 14·5 years) and follow-up surveys in 2017-2018 (mean age = 22·0 years). DESIGN Past-year food insecurity was reported at both time points, and ACE were reported at follow-up. Logistic regression models were used to estimate emerging adult food insecurity prevalence by ACE exposure; models were stratified by childhood SES (low, middle and high). RESULTS The adjusted prevalence of food insecurity was 45·3 % among emerging adults who reported three or more ACE compared with 23·6 % among those with one or two ACE and 15·5 % among those with no ACE (P < 0·001). All forms of ACE were related to an elevated prevalence of food insecurity in emerging adulthood. ACE-food insecurity associations were strongest for emerging adults from lower and middle SES households. Among emerging adults from low SES households, childhood experiences of emotional abuse and substance use by a household member were associated with the largest prevalence differences in food insecurity. CONCLUSIONS Findings suggest a need for trauma-informed services within food assistance programs to better serve individuals with a history of ACE.

Abstract
INTRODUCTION Despite research showing substantial weight disparities along the rural-urban continuum, little work has attempted to identify differences in prepregnancy weight status or gestational weight gain (GWG) outcomes between rural and urban birthing people. As such, the goals of this research were to 1) document the prevalence of prepregnancy overweight and obesity and excessive GWG in rural and urban birthing people and 2) examine changes in rural and urban prepregnancy overweight or obesity and excessive GWG over time. METHODS Birth certificate data provided sociodemographic variables, prepregnancy body mass index, GWG, and rurality status on 465,709 respondents who gave birth in Minnesota from 2012 to 2019. A series of regression models estimated risk differences in 1) prepregnancy weight status and 2) excessive GWG between rural and urban respondents over time, controlling for relevant covariates. RESULTS Rural individuals had a 4.9 percentage-point (95% confidence interval, 4.5-5.3) higher risk of having prepregnancy overweight or obesity compared with urban individuals, and a 2.6 percentage-point (95% confidence interval, 1.9-3.3) higher risk of gaining excessive gestational weight. The disparities in prepregnancy overweight or obesity and excessive gestational weight between rural and urban individuals widened over time. CONCLUSIONS These findings contribute to accumulating evidence documenting notable health disparities between rural and urban individuals during the perinatal period and support the need to develop prevention and treatment efforts focused on improving the weight-related health of individuals living in rural communities.

Abstract
Background: Gonorrhea incidence in the United States has risen by nearly 50% in the last decade, while screening rates have increased. Gonorrhea sequelae rates could indicate whether increased gonorrhea incidence is due to better screening. We estimated the association of gonorrhea diagnosis with pelvic inflammatory disease (PID), ectopic pregnancy (EP), and tubal factor infertility (TFI) in women and detected changes in associations over time. Materials and Methods: This retrospective cohort study included 5,553,506 women aged 18-49 tested for gonorrhea in the IBM MarketScan claims administrative database from 2013-2018 in the United States. We estimated incidence rates and hazard ratios (HRs) of gonorrhea diagnosis for each outcome, adjusting for potential confounders using Cox proportional hazards models. We tested the interaction between gonorrhea diagnosis and the initial gonorrhea test year to identify changes in associations over time. Results: We identified 32,729 women with a gonorrhea diagnosis (mean follow-up time in years: PID = 1.73, EP = 1.75, TFI = 1.76). A total of 131,500 women were diagnosed with PID, 64,225 had EP, and 41,507 had TFI. Women with gonorrhea diagnoses had greater incidence per 1000 person-years for all outcomes (PID = 33.5, EP = 9.4, TFI = 5.3) compared to women without gonorrhea diagnoses (PID = 13.9, EP = 6.7, TFI = 4.3). After adjustment, HRs were higher in women with a gonorrhea diagnosis vs. those without [PID = 2.29 (95% confidence interval, CI: 2.15-2.44), EP = 1.57, (95% CI: 1.41-1.76), TFI = 1.70 (95% CI: 1.47-1.97)]. The interaction of gonorrhea diagnosis and test year was not significant, indicating no change in relationship by initial test year. Conclusion: The relationship between gonorrhea and reproductive outcomes has persisted, suggesting a higher disease burden.

Abstract
OBJECTIVE A growing body of literature suggests that the COVID-19 pandemic is a traumatic stressor capable of causing posttraumatic stress symptoms. People with a history of trauma, particularly those with posttraumatic stress disorder (PTSD), may be particularly vulnerable to the negative mental health impacts of the pandemic. However, qualitative research exploring potential differences in the lived experiences of and reactions to COVID-19 between people with and without PTSD is lacking. METHOD Semistructured interviews were conducted with 31 women (n = 15 women with probable PTSD, n = 16 women without probable PTSD) recruited from an ongoing U.S.-based cohort study. Themes were identified using inductive thematic analysis. RESULTS The majority of women with PTSD described their level of fear or perceived safety related to COVID-19 as a major factor influencing their mental health during the pandemic. In contrast, women without PTSD indicated that their level of distress was largely driven by pandemic-related restrictions on normal activities and family events. Many women with PTSD also described feeling anger or frustration toward people they perceived as not taking the COVID-19 pandemic seriously. Only one participant without PTSD expressed similar feelings. CONCLUSIONS This study found notable differences in reactions to the COVID-19 pandemic between people with and without PTSD, with findings that are likely relevant to future disasters. These findings can inform the development of preparedness policies for future disasters, pandemics, or other collective traumas to prevent distress and improve mental health, particularly for vulnerable populations such as individuals with preexisting PTSD.

Abstract
Pap tests are still underutilized by minority women due to limited awareness of cervical cancer screening (CCS), inadequate health care access, and cultural or religious beliefs. Human papillomavirus (HPV) self-sampling, a new CCS tool, has demonstrated potential to overcome some of these barriers. In 2021, women aged 30-65 years old were recruited across Minnesota to complete an online survey. The survey assessed five outcome measures related to HPV self-sampling: (1) awareness of test; (2) self-efficacy to conduct test; (3) location preference of test (clinic vs. home); 4) collector preference (self vs. clinician); and (5) preference of CCS strategy (HPV self-sampling vs. Pap test). Modified Poisson regressions tested associations between sociodemographic variables and outcomes. A total of 420 women completed the survey, of which 32.4% identified as Non-Hispanic white, 22.2% as Hispanic, 12.6% as Black/African-American, 28.3% as Asian, 1.9% as American Indian/Alaskan Native, and 1.4% as more than two races. Few women had heard of HPV self-sampling (6.5%), but a majority reported high self-efficacy to perform self-sampling (75.3%). Women also reported higher preferences for completing an HPV test in the clinic (52.2%) and for performing a self-collected HPV test themselves (58.7%), yet would choose a traditional Pap test over HPV self-sampling (56.0%). The low level of HPV self-sampling awareness, across all racial/ethnic groups, suggests a strong opportunity to promote widespread educational efforts around this new tool. Future HPV self-sampling research efforts should examine educational interventions targeted at healthcare providers to educate and encourage women on the importance of self-collection options.

Abstract
Background: This study examined the associations between BMI trajectories and emerging cardiometabolic risk (CMR) in children living in low-income and racially and ethnically diverse households in the United States. Methods: Data were drawn from NET-Works randomized intervention trial and NET-Works 2 prospective follow-up study (N = 338). BMI was measured across 6 follow-up visits and biomarkers of cardiometabolic risk (CMR) at the sixth visit. Group-based trajectory modeling identified child BMI trajectories. Adjusted multivariable linear regressions evaluated the associations between BMI trajectories and CMR. Results: We identified two BMI trajectories: 25% followed a trajectory of steep BMI increase, and 75% followed a moderate decreasing BMI trajectory over time. Relative to children in the moderate decreasing trajectory, children in the increasing trajectory had higher adjusted mean levels of C-reactive protein [CRP; 3.3; 95% confidence interval (CI): 1.6 to 5.0], leptin (63.1; 95% CI: 44.3 to 81.8), triglycerides (35.4; 95% CI: 22.1 to 48.6), triglyceride/high-density lipoprotein (HDL) ratio (1.2; 95% CI: 0.8 to 1.6), hemoglobin A1c (HbA1C; 0.1; 95% CI: 0.03 to 0.2), fasting glucose (1.8; 0.1 to 3.5) and insulin (8.8; 95% CI: 6.5 to 11.0), overall CMR score (0.7; 95% CI: 0.5 to 0.9), and lower adiponectin (-1.3; 95% CI: -2.5 to -0.1) and HDL (-10.8; 95% CI: -14.3 to -7.4). Conclusions: Children with high BMIs early in childhood were more likely to maintain an accelerated BMI trajectory throughout childhood, which was associated with adverse CMR in pre-adolescence. To advance health equity and support children's healthy weight and cardiovascular health trajectories, public health efforts are needed to address persistent disparities in childhood obesity and CMR.

Abstract
Economic hardship during childhood has been linked to poor physical and mental health. This study examines cross-sectional and longitudinal associations of a summed economic hardship score of poverty, food insecurity, and financial hardship with hair cortisol in young children. Data from 24-month (Time 1, mean age 5 years) and 36-month (Time 2, mean age 6 years) follow-up from the NET-Works obesity prevention trial (NET-Works, NCT0166891) were used. Hair cortisol measures obtained at each time point were log-transformed and regressed on economic hardship at Time 1 and a cumulative economic hardship from Time 1 to Time 2, using generalized linear regressions. All models were adjusted for child age, sex, race/ethnicity, and intervention (prevention vs. control) arm. The final analytic sample sizes ranged from 248 to 287. Longitudinal analyses indicated that for every 1-unit higher economic hardship score at Time 1, hair cortisol at Time 2 follow-up was on average 0.07 log-picograms per milligram (pg/mg) higher (95% confidence interval [CI]: 0.01, 0.13). For every 1-unit increase in the cumulative economic hardship score between Time 1 and 2, there was a 0.04 log-pg/mg (95% CI: 0.00, 0.07) average higher level of hair cortisol at Time 2 follow-up. Results show suggestive but limited evidence for an association between economic hardship and cortisol in young children.

Abstract
Economic hardship may lead to a wide range of negative outcomes, including violence. However, existing literature on economic hardship and violence is limited by reliance on official reports of violence and conflation of different measures of economic hardship. The goals of this study are to measure how violence-related injuries are associated with five measures of county-level economic shocks: unemployment rate, male mass layoffs, female mass layoffs, foreclosure rate, and unemployment rate change, measured cross-sectionally and by a 1-year lag. This study measures three subtypes of violence outcomes (child abuse, elder abuse, and intimate partner violence). Yearly county-level data were obtained on violence-related injuries and economic measures from 2005 to 2012 for all 87 counties in Minnesota. Negative binomial models were run regressing the case counts of each violence outcome at the county-year level on each economic indicator modeled individually, with population denominator offsets to yield incidence rate ratios. Crude models were run first, then county-level socio-demographic variables and year were added to each model, and finally fully-adjusted models were run including all socio-demographic variables plus all economic indicators simultaneously. In the fully-adjusted models, a county's higher foreclosure rate is the strongest and most consistently associated with an increase in all violence subtypes. Unemployment rate is the second strongest and most consistent economic risk factor for all violence subtypes. Lastly, there appears to be an impact of gender specific to economic impacts on child abuse; specifically, male mass-lay-offs were associated with increased rates while female mass-lay-offs were associated with decreased rates. Understanding the associations of different types of economic hardship with a range of violence outcomes can aid in developing more holistic prevention and intervention efforts.

Abstract
Interest in using internet search data, such as that from the Google Health Trends Application Programming Interface (GHT-API), to measure epidemiologically relevant exposures or health outcomes is growing due to their accessibility and timeliness. Researchers enter search term(s), geography, and time period, and the GHT-API returns a scaled probability of that search term, given all searches within the specified geographic-time period. In this study, we detailed a method for using these data to measure a construct of interest in 5 iterative steps: first, identify phrases the target population may use to search for the construct of interest; second, refine candidate search phrases with incognito Google searches to improve sensitivity and specificity; third, craft the GHT-API search term(s) by combining the refined phrases; fourth, test search volume and choose geographic and temporal scales; and fifth, retrieve and average multiple samples to stabilize estimates and address missingness. An optional sixth step involves accounting for changes in total search volume by normalizing. We present a case study examining weekly state-level child abuse searches in the United States during the coronavirus disease 2019 pandemic (January 2018 to August 2020) as an application of this method and describe limitations.

Abstract
Background The risk of pregnancy-related mortality in the United States has nearly doubled since 1990, with venous thromboembolism (VTE) accounting for approximately 10% of these deaths. Objectives The objective of this study was to assess whether preexisting autoimmune disease is a risk factor for postpartum VTE. Methods Using the MarketScan Commercial and Medicare Supplemental administrative databases, a retrospective cohort study analyzed whether postpartum persons with autoimmune disease had a higher risk of postpartum VTE incidence than postpartum persons without autoimmune disease. Using International Classification of Diseases codes, we identified 757,303 individuals of childbearing age who had a valid delivery date with at least 12 weeks of follow-up. Results Individuals were, on average, 30.7 years old (SD, 5.4), and 3.7% (N = 27,997 of 757,303) of them had evidence of preexisting autoimmune disease. In covariate-adjusted models, postpartum persons with preexisting autoimmune disease had higher rates of postpartum VTE than postpartum persons without autoimmune disease (hazard ratio [HR], 1.33; 95% CI, 1.07-1.64). When analyzed by individual autoimmune disease, those with systemic lupus erythematosus (HR, 2.49; 95% CI, 1.47-4.21) and Crohn's disease (HR, 2.49; 95% CI, 1.34-4.64) were at an elevated risk of postpartum VTE compared with those without autoimmune disease. Conclusion Autoimmune disease was associated with a higher rate of postpartum VTE, with evidence that the association was most pronounced among individuals with systemic lupus erythematosus and Crohn's disease. These findings suggest that postpartum persons of childbearing age with autoimmune disease may require more monitoring and prophylactic care after delivery to prevent potentially fatal VTE events.

Abstract
Abstract
Background: Cervical cancer rates have declined since the implementation of cervical cancer screening methods such as Pap tests. However, Pap tests are still underutilized by many minority women due to limited awareness about human papillomavirus (HPV) and cervical cancer, difficulties accessing health care services, and cultural or religious beliefs. HPV self-sampling has been proposed as an alternative to overcome some of these barriers. This study aimed to assess awareness, self-efficacy, and preferences of HPV self-sampling among racially- and ethnically-diverse women. Methods: From May – November 2021, women, ages 30-65 years old, were recruited in person and virtually to complete an online survey. The survey included 15 sociodemographic questions and five outcome measures related to HPV self-sampling: (1) awareness of test; (2) self-efficacy to conduct test; (3) location preference of test (clinic vs. home); 4) collector preference for screening strategy (self-collected vs. clinician-collected); and 5) preference of cervical cancer screening strategy (HPV self-sampling vs. Pap test). Modified Poisson regression was conducted to assess exploratory associations between sociodemographic variables and each outcome measure; relative risks were adjusted for age. Results: A total of 420 women completed the online survey, of which 32.4% identified as non-Hispanic white, 22.2% as Hispanic, 12.6% as Black/African American, 28.3% as Asian, 1.9% as American Indian/Alaskan Native, and 1.4% as more than two races. The majority of women had not heard of HPV self-sampling (93.5%) but reported high self-efficacy (75.3%). Women also reported higher preferences for completing an HPV test in the clinic (52.2%) and for performing a self-collected HPV test themselves (58.7%) yet would choose a traditional Pap test over HPV self-sampling (56.0%). Conclusion: The low level of HPV self-sampling awareness, across all racial and ethnic groups, suggests a strong opportunity to promote widespread educational efforts around this new tool. While many women, including those that are racially- and ethnically-diverse, still prefer the Pap test, the biggest barrier to their potential uptake of HPV self-sampling is a strong reliance on provider expertise. Future research should leverage the provider role in HPV self-sampling interventions as well as explore the feasibility of home-based or clinic-based HPV self-sampling approaches.

Abstract
BACKGROUND Persistent infection with high-risk human papillomavirus (hrHPV) types is a well-documented cause of cervical cancer. Since the implementation of cervical cancer screening methods (e.g., Pap tests), cervical cancer rates have declined. However, Pap tests are still unacceptable to many women and require complex infrastructure and training. Self-sampling techniques for collecting HPV specimens (or "HPV self-sampling") have been proposed as a possible alternative to overcome these barriers. The objective of this study was to capture perspectives from health care personnel (providers, leaders, and clinic staff) across primary care systems on the potential implementation of an HPV self-sampling practice. METHODS Between May and July 2021, a study invitation was emailed to various health care professional networks across the Midwest, including a snowball sampling of these networks. Eligible participants were invited to a 45-60-min Zoom-recorded interview session and asked to complete a pre-interview survey. The survey collected sociodemographics on age, occupation, level of educational attainment, race/ethnicity, gender, and awareness of HPV self-sampling. The semi-structured interview was guided by the Consolidated Framework for Implementation Research and asked participants about their views on HPV self-sampling and its potential implementation. All interviews were audio-recorded, transcribed, and analyzed using NVivo 12. RESULTS Key informant interviews were conducted with thirty health care personnel-13 health care providers, 6 clinic staff, and 11 health care leaders-from various health care systems. Most participants had not heard of HPV self-sampling but reported a general enthusiasm for wanting to implement it as an alternative cervical cancer screening tool. Possible barriers to implementation were knowledge of clinical evidence and ease of integration into existing clinic workflows. Potential facilitators included the previous adoption of similar self-sampling tools (e.g., stool-based testing kits) and key decision-makers. CONCLUSION Although support for HPV self-sampling is growing, its intervention's characteristics (e.g., advantages, adaptability) and the evidence of its clinical efficacy and feasibility need to be better disseminated across US primary care settings and its potential adopters. Future research is also needed to support the integration of HPV self-sampling within various delivery modalities (mail-based vs. clinic-based).

Abstract
Childhood maltreatment (abuse and neglect) is associated with a range of negative outcomes, but a gap remains in understanding of how specific maltreatment types, particularly neglect and non-familial sexual abuse, relate to health and behavior. This study examined the association of neglect and sexual abuse (both familial and non-familial), as well as familial physical and emotional abuse, with: depressive mood and eating disorders; tobacco and marijuana use; and BMI ≥ 25 kg/m2 and BMI ≥ 30 kg/m2 in young adults. Data came from Project EAT (Eating and Activity in Teens and Young Adults), a population-based longitudinal study of weight-related health from adolescence into young adulthood. Maltreatment before age 18 was retrospectively reported at ages 26-33. Risk differences (RDs) and 95% confidence intervals (CIs) were estimated for those with a given maltreatment type to those without, and also for the cumulative number of maltreatment types experienced. One in 3 participants reported abuse or neglect. All maltreatment types were associated with at least one adverse health outcome, with physical abuse being least consistently related to the outcomes. Emotional abuse showed the strongest association with depressive mood. All maltreatment types were associated with eating disorder diagnosis, tobacco use, and marijuana use (except physical abuse for eating disorder). There was little evidence of a maltreatment association with BMI ≥ 25 kg/m2; emotional abuse and neglect were associated with BMI ≥ 30 kg/m2. Prevention of maltreatment needs to be a top public health priority.

Abstract
Substantial evidence suggests that economic hardship causes violence. However, a large majority of this research relies on observational studies that use traditional violence surveillance systems that suffer from selection bias and over-represent vulnerable populations, such as people of color. To overcome limitations of prior work, we employed a quasi-experimental design to assess the impact of the Great Recession on explicit violence diagnoses (injuries identified to be caused by a violent event) and proxy violence diagnoses (injuries highly correlated with violence) for child maltreatment, intimate partner violence, elder abuse, and their combination. We used Minnesota hospital data (2004-2014), conducting a difference-in-differences analysis at the county level (n = 86) using linear regression to compare changes in violence rates from before the recession (2004-2007) to after the recession (2008-2014) in counties most affected by the recession, versus changes over the same time period in counties less affected by the recession. The findings suggested that the Great Recession had little or no impact on explicitly identified violence; however, it affected proxy-identified violence. Counties that were more highly affected by the Great Recession saw a greater increase in the average rate of proxy-identified child abuse, elder abuse, intimate partner violence, and combined violence when compared with less-affected counties.

Abstract
ObjectiveTo evaluate female students' expectations and experiences related to their sexual and reproductive health (SRH) during international travel. Participants: Female students from a US university with a history of sex with men completed a cross-sectional survey about their upcoming (Pre-travelers; n = 170) or recent (Travelers; n = 340) international travel. Methods: Descriptive statistics were used to characterize pre-travel SRH expectations (for Pre-travelers) and to determine the prevalence of 15 SRH experiences during both recent and lifetime travel (for Travelers). Results: Pre-travelers overwhelmingly expected to be abstinent and many were unsure of whether SRH supplies would be accessible in their destination. During Travelers' recent trip, SRH experiences included getting off schedule with contraception (30%), unwanted sexual touching (18%), new male sex partners (17%), and unexpected sex (15%); lifetime prevalence estimates were higher. Conclusions: International travel poses risks to female students' SRH that can be addressed by pre-travel counseling from study-abroad programs and clinicians.

Abstract
Adverse childhood experiences (ACEs) include childhood abuse, neglect, and household substance abuse. Childhood abuse is a risk factor for disordered eating (DEB). Less well established are associations of childhood neglect and household substance abuse with DEB, and little research has examined ACE associations with DEB in middle adulthood. The objective of this study was to examine associations between ACEs and DEBs among middle-aged adults and examine sex differences. ACEs prior to age 18 were retrospectively assessed in the Coronary Artery Risk Development in Young Adults study in 2000-2001 (N = 3340, ages 32 to 46). DEB outcomes (i.e., concerns about weight and shape, anxiety about eating or food, unhealthy weight control behaviors, chronic dieting, overeating, and binge eating) were assessed in 1995-1996 (ages 27 to 41). Modified Poisson regressions estimated risk ratios (RRs) for associations of a history of any ACE, each ACE, and cumulative ACEs with DEB outcomes. Among women, emotional abuse, physical neglect, and emotional neglect were each modestly associated with most DEBs (RRs = 1.21-1.35, 1.21-1.45, and 1.23-1.41 across DEBs, respectively) after adjustment for sociodemographic variables, BMI, and depressive symptoms. A cumulative ACE score was associated with all DEBs in a stepwise manner (p for trend ≤0.05) except concerns about weight and shape and overeating. Among men, emotional abuse was most consistently related to the majority of DEBs (RRs = 1.23-1.92); household substance abuse was modestly associated with overeating (RR = 1.26, 95% CI = 1.04-1.53). ACEs were cumulatively associated with unhealthy weight control behaviors, overeating, and binge eating (p for trend <0.01).

Abstract
BACKGROUND The COVID-19 pandemic has created environments with increased risk factors for household violence, such as unemployment and financial uncertainty. At the same time, it led to the introduction of policies to mitigate financial uncertainty. Further, it hindered traditional measurements of household violence. OBJECTIVE Using an infoveillance approach, our goal was to determine if there were excess Google searches related to exposure to child abuse, intimate partner violence (IPV), and child-witnessed IPV during the COVID-19 pandemic and if any excesses are temporally related to shelter-in-place and economic policies. METHODS Data on relative search volume for each violence measure was extracted using the Google Health Trends application programming interface for each week from 2017 to 2020 for the United States. Using linear regression with restricted cubic splines, we analyzed data from 2017 to 2019 to characterize the seasonal variation shared across prepandemic years. Parameters from prepandemic years were used to predict the expected number of Google searches and 95% prediction intervals (PI) for each week in 2020. Weeks with searches above the upper bound of the PI are in excess of the model's prediction. RESULTS Relative search volume for exposure to child abuse was greater than expected in 2020, with 19% (10/52) of the weeks falling above the upper bound of the PI. These excesses in searches began a month after the Pandemic Unemployment Compensation program ended. Relative search volume was also heightened in 2020 for child-witnessed IPV, with 33% (17/52) of the weeks falling above the upper bound of the PI. This increase occurred after the introduction of shelter-in-place policies. CONCLUSIONS Social and financial disruptions, which are common consequences of major disasters such as the COVID-19 pandemic, may increase risks for child abuse and child-witnessed IPV.

Abstract
PURPOSE Growing evidence indicates that experiencing household food insecurity during adolescence is associated with disordered eating and elevated body mass index (BMI). However, little is known about the temporal nature of these relationships. The current longitudinal study examined how adolescent experiences of household food insecurity are related to disordered eating and weight status 8 years later. METHODS A population-based sample of ethnically/racially and socioeconomically diverse participants (n = 1,340) were surveyed as adolescents (mean age = 14.5 years) and as young adults (mean age = 22.0 years). Parents/caregivers completed the six-item U.S. Household Food Security Survey Module at baseline. RESULTS Household food insecurity was common at baseline (37.8% of sample). In analyses adjusted for ethnicity/race and parental education, adolescent food insecurity longitudinally predicted a higher new onset of binge eating (food insecure: 21.3% vs. food secure: 16.2%, p = .038) and BMI ≥30 kg/m2 (food insecure: 15.9% vs. food secure: 11.0%, p = .024), but not unhealthy weight control behaviors in young adulthood. The majority of adolescents with unhealthy weight control behaviors and elevated BMI still had these problems in young adulthood, but persistence was not associated with adolescent household food insecurity for any outcome. DISCUSSION Results of this longitudinal study suggest that household food insecurity during adolescence is a risk factor for disordered eating and elevated BMI in young adulthood, highlighting a need to comprehensively address these intersecting problems.

Abstract
Childhood and adult adversities occur more frequently among women and persons of colour, possibly influencing racial/ethnic disparities in substance use behaviours. This study investigates how childhood and adult adversities cluster together by race/ethnicity and how these clusters predict binge drinking, tobacco, e-cigarette, and marijuana use. Latent class analysis (LCA) was used in a combined sample from the 2015 to 2018 Minnesota College Student Health Survey to identify clusters of childhood and adult adversities among Asian, Black, Latina, and White women aged 18-25. Each substance use outcome was regressed on each adversity cluster across each race/ethnicity group. Across all racial/ethnic groups and substance use outcomes, the high adversity cluster exhibited the greatest risk. Significant racial/ethnic disparities were observed across several substance use behaviours; these were attenuated among women with fewer adversities. The reduced substance use disparities found among those with lower adversities suggest that prevention of adversities may advance health equity.

Abstract
Various types of stressors are associated with maladaptive eating, but how the stressor of everyday discrimination (e.g., less respect, poorer service) relates to maladaptive eating and adaptive eating remains unclear. We examined everyday discrimination as a predictor of maladaptive and adaptive eating. Data were collected in a population-based study, Eating and Activity over Time (N = 1410, ages 18-30). Everyday discrimination was categorized as none, low, moderate, or high. Outcomes included maladaptive eating (i.e., overeating and binge eating) and adaptive eating (i.e., intuitive eating and mindful eating). Modified Poisson regressions estimated the prevalence ratios (PRs) for overeating and binge eating associated with everyday discrimination. Linear regressions estimated associations between everyday discrimination and intuitive and mindful eating scores. After adjustment for age, ethnicity/race, gender, and socioeconomic status, moderate and high levels of discriminatory experiences were each associated with a significantly greater prevalence of binge eating (PR = 2.2, [95% CI = 1.3-3.7] and PR = 3.1, [95% CI = 2.0-4.7], respectively) and lower intuitive (β = -0.4, [95% CI = -0.7, -0.2] and β = -0.5 [95% CI = -0.8, -0.3], respectively), and mindful eating scores (β = -0.3, [95% CI = -0.6, -0.1] and β = -0.5 [95% CI = -0.8, -0.3], respectively) compared to young adults with no discriminatory experience. Public health efforts to prevent maladaptive eating and encourage the adoption of adaptive eating should consider the potential contribution of everyday discrimination and the need to advocate for equity and inclusion.

Abstract
PURPOSE Despite recommendations from the World Health Organization and the American Academy of Pediatrics to exclusively breastfeed infants for their first 6 months of life, 75% of women do not meet exclusive breastfeeding guidelines, and 60% do not meet their own breastfeeding goals. Numerous observational studies have linked maternal psychological distress (eg, perceived stress, anxiety, and depression) with nonoptimal breastfeeding outcomes, such as decreased proportion and duration of exclusive breastfeeding. The physiological mechanisms underlying these associations, however, remain unclear. METHODS For this narrative review, we evaluated the evidence of relationships between maternal psychological distress and lactation and breastfeeding outcomes in pregnancy and post partum and the possible physiological mechanisms that facilitate these relationships. We searched PubMed using the following terms: stress, anxiety, depression, breastfeeding, and lactation. Additional search by hand was conducted to ensure a thorough review of the literature. FINDINGS Among the studies examined, methods used to assess maternal psychological distress were not uniform, with some studies examining perceived distress via a variety of validated tools and others measuring biological measures of distress, such as cortisol. Evidence supports a role for psychological distress in multiple breastfeeding outcomes, including delayed secretory activation and decreased duration of exclusive breastfeeding. One physiological mechanism proposed to explain these relationships is that psychological distress may impair the release of oxytocin, a hormone that plays a critical role in milk ejection during lactation. Continued impairment of milk ejection may lead to decreased milk production because of incomplete emptying of the breast during each feed. Maternal distress may also yield elevated levels of serum cortisol and decreased insulin sensitivity, which are associated with decreased milk production. The relationship between psychological distress and breastfeeding is likely to be bidirectional, however, in that breastfeeding appears to reduce maternal distress, again possibly via effects on the pleasure or reward pathway and calming effects of oxytocin on the mother. This finding suggests that interventions to support lactation and breastfeeding goals in women who score high on measures of psychological distress would be beneficial for both maternal and infant well-being. IMPLICATIONS Evidence to date suggests that maternal psychological distress may impair lactation and breastfeeding outcomes, but stronger study designs and rigorous assessment methods are needed. A better understanding of the physiological mechanisms leading to impaired lactation may assist in the development of early interventions for mothers experiencing distress. In addition, stress-reducing programs and policies should be investigated for their potential to improve breastfeeding outcomes.

Abstract
Adverse experiences, such as childhood abuse and other violence victimization, are associated with problematic eating. However, whether different types of adversity relate to both maladaptive and adaptive eating behaviors is unclear. This study examined the associations of different adverse experiences with maladaptive (i.e., overeating and binge eating) and adaptive (i.e., intuitive eating and mindful eating) eating by gender. Data were derived from the EAT-2018 (Eating and Activity over Time) study (N = 1411, aged 18-30 years in 2017-2018). Modified Poisson regressions were used to examine the associations between adverse experiences and the prevalence of maladaptive eating. Linear regressions were used to examine the associations between adverse experiences and adaptive eating scores. Each adverse experience was associated with greater prevalence of maladaptive eating and lower adaptive eating scores. Among women, intimate partner sexual violence was strongly associated with more overeating (PR = 2.1 [95% CI = 1.4-3.1]) and binge eating (PR = 2.4 [95% CI = 1.5-3.9]), and less mindful eating (β = -0.6, [95% CI = -0.8, -0.3]); being attacked, beaten, or mugged was most associated with less intuitive eating (β = -0.5, [95% CI = -0.8, -0.2]). Among men, being attacked, beaten, or mugged was strongly associated with more overeating (PR = 2.1 [95% CI = 1.2-3.5]) and binge eating (PR = 3.2 [95% CI = 1.6-6.5]); intimate partner physical violence was strongly associated with less intuitive eating (β = -0.6, [95% CI = -0.9, -0.2]); childhood emotional abuse was strongly associated with less mindful eating (β = -0.8, [95% CI = -1.0, -0.5]). To improve eating behaviors, adverse life experiences and the potential impact on maladaptive and adaptive eating should be considered.

Abstract
OBJECTIVE The study aims were to (1) document the relationship between a history of childhood abuse and weight change during behavioral obesity treatment and (2) estimate the indirect effect of childhood abuse on weight change through binge eating severity. METHODS Participants (n = 431) were enrolled in a behavioral weight-loss intervention. Childhood physical and emotional abuse history and current binge eating severity were self-reported. Percent weight loss at 6 months was calculated using measured weight. Adjusted mediation models examined whether there was an indirect effect of childhood physical and emotional abuse on 6-month percent weight loss that operated through binge eating severity. RESULTS After covariate adjustment, childhood physical abuse, but not emotional abuse, predicted a lower percent weight loss (B = -1.78%; 95% CI: -3.10% to -0.47%). Although childhood physical and emotional abuse were positively related to baseline binge eating severity, binge eating severity did not mediate the associations between either childhood abuse type and percent weight loss. CONCLUSIONS Individuals with a childhood physical abuse history had a lower percent weight loss than those without such histories during behavioral obesity treatment. This effect was not explained by binge eating severity. Individuals with a history of childhood abuse may benefit from trauma-informed obesity care.

Abstract
This cross-sectional study examines the association of childhood and adolescent/adult adversities with obesity across four racial/ethnic groups among emerging adult women aged 18 to 25 (n = 9310). Latent class analysis was used to identify racial/ethnicity-specific classes arising from childhood and adolescent/adult adversity indicators in the 2015 and 2018 College Student Health Surveys (sampled from Minnesota, U.S.) Distal outcome procedure and Bolck-Croon-Hagenaars methods were used to assess each class's association with body mass index (BMI) and obesity probability. Models were adjusted for post-secondary school type and parental education. We identified 7 classes for White women, 4 classes for Asian and Latina women, and 5 classes for Black women. Weight distributions of Black and Latina women leaned towards "overweight", whereas White and Asian women's BMI leaned towards "normal weight." Latina and Black women had a wider BMI range (~5 kg/m2) between classes with the highest versus lowest BMI than White and Asian women (~3 kg/m2), suggesting a stronger association between adversities and BMI. For Asian, Black, and White women, the "Low Adversities" class had the lowest obesity prevalence, while the "High Lifetime Adversities" class had the highest prevalence. In contrast, Latina women had the lowest obesity prevalence in the "High Adolescent/Adult Adversities & Low Childhood Adversities" class, and highest prevalence in the "Household Mental Illness" class. Results indicate that racial/ethnic disparities in obesity-related measures are reduced when racial/ethnic groups experience low adversity. Future research should explore tailored adversity interventions that consider adversity exposure differences across race/ethnicity as a strategy for reducing obesity risk.

Abstract
BACKGROUND The Supplemental Nutrition Assistance Program (SNAP) is the largest anti-hunger program in the United States. Two proposed interventions to encourage healthier food expenditures among SNAP participants have generated significant debate: financial incentives for fruits and vegetables, and restrictions on foods high in added sugar. To date, however, no study has assessed the impact of these interventions on the benefit cycle, a pattern of rapid depletion of SNAP benefits that has been linked to worsening nutrition and health outcomes over the benefit month. METHODS Low-income households not currently enrolled in SNAP (n = 249) received benefits every 4 weeks for 12 weeks on a study-specific benefit card. Households were randomized to one of four study arms: 1) incentive (30% incentive for fruits and vegetables purchased with study benefits), 2) restriction (not allowed to buy sugar-sweetened beverages, sweet baked goods, or candy using study benefits), 3) incentive plus restriction, or 4) control (no incentive or restriction). Weekly household food expenditures were evaluated using generalized estimating equations. RESULTS Compared to the control group, financial incentives increased fruit and vegetable purchases, but only in the first 2 weeks after benefit disbursement. Restrictions decreased expenditures on foods high in added sugar throughout the benefit month, but the magnitude of the impact decreased as the month progressed. Notably, restrictions mitigated cyclical expenditures. CONCLUSIONS Policies to improve nutrition outcomes among SNAP participants should consider including targeted interventions in the second half of the month to address the benefit cycle and attendant nutrition outcomes.

Abstract
BACKGROUND Sexual and physical abuse are risk factors for binge eating and overeating, but few studies have examined association of the identity of the perpetrator with survivors' risk of binge eating and overeating. PURPOSE To examine the risk of binge eating and overeating by (1) type of abuse and identity of the perpetrators and (2) cumulative abuse experiences/perpetrators. METHODS Data came from Eating and Activity over Time (N = 1407; ages 18-30 during 2017-2018). Sexual abuse perpetrators included family members, non-family members, and intimate partners. Physical abuse perpetrators included family members and intimate partners. Cumulative abuse experiences were defined as the number of types of abuse experienced. Modified Poisson regressions were used to examine the risk of binge eating (overeating with loss of control) and overeating (without loss of control), by (1) abuse type and perpetrator and (2) cumulative abuse experiences. RESULTS Abuse was more strongly associated with binge eating than overeating. For binge eating, risk factors included familial and intimate partner sexual abuse (RR = 1.48 [95% CI = 1.01-2.17] and 2.41, [95% CI = 1.70-3.41], respectively) and physical abuse (RR = 1.84, [95% CI = 1.33-2.53] and 1.95, [95% CI = 1.35-2.81], respectively), after adjustment for sociodemographic variables. For overeating, associations with physical abuse were close to the null, and those with sexual abuse were modest, with wide CIs that overlapped the null. Abuse experiences were cumulatively associated with binge eating, but not overeating. CONCLUSION Assessment of identity of the perpetrator, and cumulative abuse experiences/perpetrators may assist in identifying people at the greatest risk of binge eating.

Abstract
BACKGROUND Adverse childhood experiences (ACEs) are associated with a range of health problems, yet protective factors such as self-compassion may help buffer these associations. OBJECTIVE This study examined associations of distinct patterns of ACEs with depressive symptoms, body mass index (BMI), and disordered eating symptoms and investigated self-compassion as a potential protective factor. PARTICIPANTS AND SETTING Data from a diverse sample of 1440 emerging adults (Mage = 22.2 years; 53.7% female; 80.3% with race/ethnicity other than non-Hispanic white) came from the population-based EAT 2018 (Eating and Activity over Time) study. METHODS Seven types of ACEs were retrospectively self-reported and used as model indicators in latent class analysis to identify patterns of ACEs. Self-compassion, depressive symptoms, height and weight (to calculate BMI), and disordered eating symptoms were also assessed. Demographic-adjusted regression models were conducted. RESULTS Three latent classes emerged: "low ACEs" (66.5% of the sample), "household dysfunction" (24.3%), and "household dysfunction and abuse" (9.1%). Compared to participants in the "low ACEs" class, participants in either latent class involving household dysfunction demonstrated higher levels of depressive and disordered eating symptoms. Participants in the "household dysfunction and abuse" class also had higher BMI. Associations differed by self-compassion for depressive symptoms (pinteraction = 0.01), BMI (pinteraction = 0.03), and disordered eating symptoms (pinteraction = 0.005), such that associations for latent classes characterized by ACEs were weaker with higher levels of self-compassion. CONCLUSIONS These findings suggest self-compassion may act as a buffer against adverse mood-, weight-, and eating-related outcomes in the face of adversity and therefore may be an important intervention target.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic increased mothers’ caregiving demands, potentially placing them at increased risk for reduced engagement in healthful behaviors and high psychological distress. Purpose The purpose of this study was to describe perceived changes in moderate-vigorous physical activity (MVPA) and sedentary behaviors and the prevalence of different measures of psychological distress (depressive and anxiety symptoms, perceived stress, and positive and negative affect) among mothers. We also evaluated the associations of perceived change in MVPA and sedentary behaviors with measures of psychological distress. Methods We conducted a cross-sectional survey with 317 mothers living with children (0–20 years old) at home. Mothers self-reported perceived changes in MVPA and sedentary behaviors from before the pandemic to during COVID-19 stay-at-home orders and early reopening, and levels of depression and anxiety symptomatology, perceived stress, and positive and negative affect during the pandemic. Results Compared to pre-pandemic levels, 39% of mothers reported engaging less in MVPA, and 63% reported engaging in more sedentary activities. One-quarter and 31% of mothers reported moderate/severe depressive and anxiety symptoms, respectively, and 78% medium/high levels of perceived stress. Adjusted linear regression analyses revealed that reduced MVPA and increased sedentary behaviors were associated with high average scores of depressive and anxiety symptoms, perceived stress, negative affect, and low scores of positive affect. Conclusion A large proportion of mothers reported being less physically active and more engaged in sedentary behaviors, which were associated with increases in psychological distress. Clinical and public health intervention efforts should consider how to improve mothers’ physical and mental health as the country emerges from this crisis.

Abstract
PURPOSE Commonly-used violence surveillance systems are biased towards certain populations due to overreporting or over-scrutinized. Hospital discharge data may offer a more representative view of violence, through use of proxy codes, i.e. diagnosis of injuries correlated with violence. The goals of this paper are to compare the trends in violence in Minnesota, and associations of county-level demographic characteristics with violence rates, measured through explicitly diagnosed violence and proxy codes. It is an exploration of how certain sub-populations are overrepresented in traditional surveillance systems. METHODS Using Minnesota hospital discharge data linked with census data from 2004 to 2014, this study examined the distribution and time trends of explicit, proxy, and combined (proxy and explicit) codes for child abuse, intimate partner violence (IPV), and elder abuse. The associations between county-level risk factors (e.g., poverty) and county violence rates were estimated using negative binomial regression models with generalized estimation equations to account for clustering over time. RESULTS The main finding was that the patterns of county-level violence differed depending on whether one used explicit or proxy codes. In particular, explicit codes suggested that child abuse and IPV trends were flat or decreased slightly from 2004 to 2014, while proxy codes suggested the opposite. Elder abuse increased during this timeframe for both explicit and proxy codes, but more dramatically when using proxy codes. In regard to the associations between county level characteristics and each violence subtype, previously identified county-level risk factors were more strongly related to explicitly-identified violence than to proxy-identified violence. Given the larger number of proxy-identified cases as compared with explicit-identified violence cases, the trends and associations of combined codes align more closely with proxy codes, especially for elder abuse and IPV. CONCLUSIONS Violence surveillance utilizing hospital discharge data, and particularly proxy codes, may add important information that traditional surveillance misses. Most importantly, explicit and proxy codes indicate different associations with county sociodemographic characteristics. Future research should examine hospital discharge data for violence identification to validate proxy codes that can be utilized to help to identify the hidden burden of violence.

Abstract
Assessing drug response within live native tissue provides increased fidelity with regards to optimizing efficacy while minimizing off-target effects. Here, using longitudinal intravital imaging of a Rac1-Förster resonance energy transfer (FRET) biosensor mouse coupled with in vivo photoswitching to track intratumoral movement, we help guide treatment scheduling in a live breast cancer setting to impair metastatic progression. We uncover altered Rac1 activity at the center versus invasive border of tumors and demonstrate enhanced Rac1 activity of cells in close proximity to live tumor vasculature using optical window imaging. We further reveal that Rac1 inhibition can enhance tumor cell vulnerability to fluid-flow-induced shear stress and therefore improves overall anti-metastatic response to therapy during transit to secondary sites such as the lung. Collectively, this study demonstrates the utility of single-cell intravital imaging in vivo to demonstrate that Rac1 inhibition can reduce tumor progression and metastases in an autochthonous setting to improve overall survival.

Abstract
High levels of the anti-apoptotic BCL-2 family member MCL-1 are frequently found in breast cancer and, appropriately, BH3-mimetic drugs that specifically target MCL-1's function in apoptosis are in development as anti-cancer therapy. MCL-1 also has reported non-canonical roles that may be relevant in its tumour-promoting effect. Here we investigate the role of MCL-1 in clinically relevant breast cancer models and address whether the canonical role of MCL-1 in apoptosis, which can be targeted using BH3-mimetic drugs, is the major function for MCL-1 in breast cancer. We show that MCL-1 is essential in established tumours with genetic deletion inducing tumour regression and inhibition with the MCL-1-specific BH3-mimetic drug S63845 significantly impeding tumour growth. Importantly, we found that the anti-tumour functions achieved by MCL-1 deletion or inhibition were completely dependent on pro-apoptotic BAX/BAK. Interestingly, we find that MCL-1 is also critical for stem cell activity in human breast cancer cells and high MCL1 expression correlates with stemness markers in tumours. This strongly supports the idea that the key function of MCL-1 in breast cancer is through its anti-apoptotic function. This has important implications for the future use of MCL-1-specific BH3-mimetic drugs in breast cancer treatment.

Abstract
PURPOSE Well-child care is the foundation of pediatric health promotion and disease prevention. Primary care quality is lower for low-income and African American children compared to white children, and social determinants have an increasingly acknowledged impact on child health. Ensuring that high-quality well-child care fulfills its potential to mitigate the negative effects of social determinants on African American children is imperative. This study provides an understanding of urban, low-income, African American well-child care experiences and expectations. DESIGN AND METHODS A qualitative, focus group method was used. A purposive, volunteer sample of low-income, African American parents with children birth to age five was recruited from St. Louis and Milwaukee. Focus groups were held in convenient, community sites. Data was audio-digitally recorded. Transcribed data were coded and analyzed through inductive content analysis. RESULTS Thirty-five caregivers, 86% females, participated in four focus groups. Categories (and sub-categories) identified include: Community factors (We want better schools, It's getting more rough where I live); Sources of parenting advice (Google it, Call your parent, Older remedies); System challenges (Cost, Frequent new faces, Politics); Challenges with providers (Couldn't help me, Missed something important, Treated differently, Are you really listening?); Anticipatory guidance (Breastfeeding, Discipline, Vaccines, Development); and What parents desire (Know them, trust). CONCLUSIONS This study reveals the contexts that give rise to health care disparities and provides insight into parent's healthcare behaviors. PRACTICE IMPLICATIONS Results offer providers guidance in providing well-child care for this population to improve pediatric care quality and child health.

Abstract
OBJECTIVES Urban, low-income, African American children and parents report lower quality primary care and face negative social determinants of health. High-quality well-child care is critical for this population. The purpose of this qualitative study was to compare and contrast parent and health care provider experiences of well-child care for urban, low-income, African American families to better understand the complex factors involved in care quality and health outcomes. METHODS Two data sets were analyzed using conventional content analysis, parent focus group data, and provider interviews. After analysis, results were sorted into similar categories, and convergence coding was completed to identify areas of agreement, partial agreement, dissonance, and silence. RESULTS Thirty-five parents took part in four focus groups, and nine providers were interviewed. Following convergence coding, five categories and 31 subcategories were identified. The five categories included: social determinants of health, sources of advice and support, challenges with the healthcare system, parent-provider relationships, and anticipatory guidance topics. CONCLUSIONS FOR PRACTICE Triangulation demonstrated convergence between parents and providers understanding of the concepts and functions of well-child care, however the prominence and meaning varied within each category and sub-category. The variance in agreement, areas of silence, and dissonance shed light on why the population reports lower overall quality primary care.

Abstract
Although eating disorder symptoms generally decrease in pregnancy, loss of control eating (LOC), defined by the consumption of food accompanied by a sense of being unable to control what or how much is eaten, often persists and may develop in pregnancy. Given that LOC is associated with higher weight status and psychological distress, it is important to understand factors associated with perinatal LOC. Although childhood traumatic events have been linked to LOC in non-pregnant women, the impact of such events on LOC in pregnancy is unknown. Accordingly, the present study aimed to examine the association between a history of childhood traumatic events and LOC prior to and during pregnancy among a community sample of pregnant women with overweight or obesity. Pregnant women (N = 244) were enrolled in a longitudinal study. Women completed interviews between 12 and 20 weeks gestation to document a history of childhood traumatic events and the presence of LOC in the three months prior to and during their current pregnancy. Women were assessed for LOC monthly for the remainder of pregnancy. Results from a multinomial regression model showed that women with a history of childhood traumatic events had higher odds of engaging in LOC both prior to and during pregnancy (OR = 2.52, 95% CI [1.13, 5.64], p = 0.02) but not during pregnancy only (OR = 1.58, 95% CI [0.87, 2.89], p = 0.39). These findings indicate that women with a history of childhood traumatic events may be especially prone to LOC in the months prior to conception that continues throughout pregnancy.

Abstract
The aim of this paper was to better understand how child and adult adversities cluster together into classes, and how these classes relate to body weight and obesity. Analyses included 2015 and 2018 data from emerging adults (18-25 years old) who participated in a state surveillance system of 2- and 4-year college students in Minnesota (N = 7475 in 2015 and N = 6683 in 2018). Latent Class Analyses (LCA) of 12 child and adult adversities were run stratified by gender and replicated between 2015 and 2018. The distal outcome procedure and three-step Bolck-Croon-Hagenaars approach were used to estimate predicted BMI means and predicted probabilities of obesity for each class, adjusted for covariates. The LCA identified seven classes in women and 5 in men. In women, BMI ranged from 23.9 kg/m2 in the lowest-BMI class ("Adult Adversities and Childhood Household Dysfunction"; 95% CI: 22.6-25.1) to 27.3 kg/m2 in the highest-BMI class ("High Lifetime Adversities"; 95% CI: 25.9-28.7), a statistically significant difference of 3.4 kg/m2. In men, the adjusted BMIs ranged from 24.6 kg/m2 ("Low Adversities"; 95% CI: 24.3-25.0) to 26.0 kg/m2 ("Childhood Household Mental Illness"; 95% CI: 25.1-26.9), a statistically significant difference of 1.4 kg/m2. The pattern was similar for obesity. These results indicate that specific classes of child and adult adversities are strongly associated with BMI and obesity, particularly in women. A key contribution of LCA appeared to be identification of small classes at high risk for excess weight.

Abstract
BACKGROUND Recessive dystrophic epidermolysis bullosa (RDEB) is associated with a high mortality rate due to the development of life-threatening, metastatic cutaneous squamous cell carcinoma (cSCC). Elevated transforming growth factor-beta (TGF-β) signalling is implicated in cSCC development and progression in patients with RDEB. OBJECTIVES To determine the effect of exogenous and endogenous TGF-β signalling in RDEB cSCC with a view to assessing the potential of targeting TGF-β signalling for RDEB cSCC therapy. METHODS A panel of 11 patient-derived RDEB cSCC primary tumour keratinocyte cell lines (SCCRDEBs) were tested for their signalling and proliferation responses to exogenous TGF-β. Their responses to TGF-β receptor type-1 (TGFBR1) kinase inhibitors [SB-431542 and AZ12601011 (AZA01)] were tested using in vitro proliferation, clonogenicity, migration and three-dimensional invasion assays, and in vivo tumour xenograft assays. RESULTS All SCCRDEBs responded to exogenous TGF-β by activation of canonical SMAD signalling and proliferative arrest. Blocking endogenous signalling by treatment with SB-431542 and AZ12601011 significantly inhibited proliferation (seven of 11), clonogenicity (six of 11), migration (eight of 11) and invasion (six of 11) of SCCRDEBs. However, these TGFBR1 kinase inhibitors also promoted proliferation and clonogenicity in two of 11 SCCRDEB cell lines. Pretreatment of in vitro TGFBR1-addicted SCCRDEB70 cells with SB-431542 enhanced overall survival and reduced tumour volume in subcutaneous xenografts but had no effect on nonaddicted SCCRDEB2 cells in these assays. CONCLUSIONS Targeting TGFBR1 kinase activity may have therapeutic benefit in the majority of RDEB cSCCs. However, the potential tumour suppressive role of TGF-β signalling in a subset of RDEB cSCCs necessitates biomarker identification to enable patient stratification before clinical intervention.

Abstract
Supplemental Nutrition Assistance Program (SNAP) benefits are rapidly depleted after distribution. This phenomenon, known as the benefit cycle, is associated with poor nutrition and health outcomes. Proposed interventions targeting the benefit cycle often focus on impulsive decision-making. However, it remains unclear whether shopper impulsivity is associated with food purchasing behavior. Using data from a prospective trial, we evaluate whether shopper impulsivity is associated with food purchasing behavior before and after households receive nutrition assistance. In this study, 249 low-income households in the Minneapolis-St. Paul, Minnesota, metropolitan area received monthly benefits for three months. Overall impulsivity and impulsivity subtraits of the primary shopper was assessed using the Barratt Impulsiveness Scale-11. Both total food expenditures and expenditures for two specific categories (fruits and vegetables, and foods high in added sugar) were evaluated. Generalized estimating equations were used to model household expenditures as a function of week since benefit distribution, impulsivity, and their interaction. Results showed that during the benefit period, food expenditures were cyclical and patterned by impulsivity. Shoppers with greater overall impulsivity spent $40.62 more in week 1 (p < 0.001). While more impulsive shoppers spent more on foods high in added sugar throughout the month (p < 0.05 for all weeks), no patterns were observed for fruits and vegetables. These findings suggest that greater impulsivity exacerbates cyclical food purchasing behavior. The impact of shopper impulsivity is especially notable for expenditures on foods high in added sugar. SNAP educational interventions to mitigate the benefit cycle may be strengthened by focusing on more impulsive shoppers and on strategies to reduce impulsive purchases of foods high in added sugar.

Abstract
This study examined gender differences in the association between childhood maltreatment and disordered eating attitudes and behaviors in adulthood. Data were derived from 1647 adults (ages 27-33) participating in a population-based, longitudinal study (Project EAT-IV: Eating Among Teens and Young Adults, 1998-2016). Childhood maltreatment (sexual abuse, physical abuse, emotional abuse, emotional neglect) and disordered eating attitudes and behaviors (overeating, binge eating, extreme weight control behaviors, unhealthy weight control behaviors, chronic dieting, weight and shape concerns) were assessed. Relative risk regression models were used to examine whether childhood maltreatment was related to individual disordered eating attitudes and behaviors. Gender differences in these associations were explored. A history of any childhood maltreatment was associated with more than 60% greater risk for chronic dieting and overeating, with additional associations found for binge eating, weight and shape concerns, and unhealthy weight control behaviors. All types of abuse and neglect were associated with at least one type of disordered eating outcome. Examination of the point estimates indicated that emotional neglect was most consistently related to higher risk for disordered eating attitudes and behaviors. Although there were no statistically significant gender differences in the association between childhood maltreatment and disordered eating attitudes and behaviors, the patterning of these effects highlighted unique qualitative similarities and differences in these relationships between men and women. Taken together, these findings implicate childhood maltreatment, particularly emotional neglect, as a meaningful risk factor for problematic eating outcomes in both men and women during adulthood.

Abstract
Intuitive eating has been associated with markers of better health in cross-sectional studies, but less is known about long-term associations between intuitive eating and subsequent eating and weight-related behaviors. This study assessed how intuitive eating in early adulthood is related to weight status, dieting, healthy and unhealthy weight control behaviors, and binge eating with loss of control five years later. Young adults (N = 1660) were asked about intuitive eating as part of the 2008-2009 third wave of the Project EAT (Eating and Activity in Teens and Young Adults) longitudinal cohort study. Weight status, dieting, healthy and unhealthy weight control behaviors, and binge eating with loss of control were assessed during both the third (EAT-III: mean age 25.3 ± 1.5) and fourth (EAT-IV mean age 31.1 ± 1.5) waves. In analyses adjusted for sociodemographic characteristics, both male and female intuitive eaters had a lower prevalence of high weight status and lower engagement in dieting, unhealthy weight control behaviors, and binge eating at the 5-year follow-up, compared to non-intuitive eaters. Among women, after additional adjustment for EAT-III values for the respective outcome measures, intuitive eating was unrelated to any of the behaviors studied at 5-year follow-up. Among men, intuitive eating predicted a lower likelihood of engaging in unhealthy weight control behaviors (intuitive eaters: 30.0% vs. non-intuitive: 41.9%, p = 0.002) and binge eating (intuitive eaters: 0.9% vs. non-intuitive: 1.5%, p = 0.046) independent of participating in these behaviors at EAT-III. In a population-based sample of young adults, intuitive eating was associated with better markers of eating and weight-related behaviors five years later, suggesting intuitive eating may have potential long-term benefits.

Abstract
OBJECTIVE The Project EAT Disordered Eating Attitudes and Behaviors (DEAB) scale was created from disordered eating attitudes and behaviors that tend to interrelate. To examine the appropriateness of the scale, we assessed the fit (i.e., how well a single latent factor fits a set of interrelated disordered eating attitudes and behaviors) and the convergent validity over time. METHOD Five interrelated disordered eating attitudes and behaviors were assessed in a longitudinal cohort (Project EAT, age 11 to 18 in 1998-1999, N = 1492). Confirmatory factor analysis examined the appropriateness of the DEAB scale. To examine whether individual variables function differently in relation to the latent construct across time, two models were compared: one requiring indicator-level factor loadings to remain equivalent across three time points (baseline [EAT-I], five-year follow-up [EAT-II], and 15-year follow-up [EAT-IV]), and the second allowing the factor loadings to vary over time. To examine the convergent validity, Pearson correlation with body satisfaction, self-esteem, depressive symptoms, and BMI was compared across time. RESULTS The fit indices for a single factor structure supported the use of the DEAB scale over time (standardized loadings: 0.60-0.87, 0.67-0.89, 0.59-0.77 at EAT-I, II, and IV respectively). As hypothesized, compared to fewer number of disordered eating attitudes and behaviors, greater number of attitudes and behaviors was associated with lower body satisfaction and self-esteem, and greater depressive symptoms and BMI (p < .01). DISCUSSION The Project EAT DEAB scale can be used as a proxy to measure the severity of disordered eating attitudes and behaviors over time in population-based studies.

Abstract
BACKGROUND Physical activity and sleep are two time-dependent behaviors with important health implications. The amount of time people have to engage in these behaviors may vary based on their everyday work, social circumstances (e.g., parenthood), and social location (e.g., gender). AIMS The current study aimed to explore the ways work, social circumstances, and social locations combine that lead to heterogeneity in the time-dependent health behaviors of physical activity and time spent in bed (i.e., sleep) among a young adult population. We drew upon two conceptual frameworks-Constrained Choices and an intersectionality perspective-and examined multiple work characteristics (e.g., number of jobs), social circumstances (e.g., household income), and social locations (e.g., U.S. nativity) relevant to young adulthood. METHODS 2015-2016 data from a Minneapolis-St. Paul, U.S. cohort of 1830 young adults (25-36 years) were analyzed using conditional inference tree (CIT)-a data-driven approach which identifies population sub-groups that differ in their outcome values as well as in the interacting factors that predict outcome differences. Sensitivity analyses to evaluate CIT robustness were also performed. RESULTS CITs revealed four relevant sub-groups for physical activity (sub-group averages ranged = 2.9-4.9 h per week), with working mothers achieving the least activity, and six relevant sub-groups for time in bed (range = 7.8-8.7 h per day), with full-time working men obtaining the least. In both models, parent status and employment status/hours were found to consistently differentiate behavior among women but not men. CONCLUSION According to these data, time to engage in physical activity and time in bed was constrained by particular everyday contexts (work and parent status) and the extent to which these contexts mattered also depended on gender. If replicated in other studies, results suggest equitable strategies are necessary to assist all parents and workers in engaging in these time-dependent health behaviors for long-term health.

Abstract
INTRODUCTION Loss of hospital-based intrapartum services is associated with increases in out-of-hospital births, but less is known about associations with planned home birth. This study explores the impact of distance to hospital-based intrapartum care on planned home birth. METHODS Public-use Minnesota birth certificate data were merged with Minnesota Hospital Annual Report data (2011-2016) to test the relationship of miles from maternal residence to hospital-based intrapartum care with planned home birth in Minnesota. Logistic regression models estimated the odds of a planned home birth versus hospital birth as a function of miles to hospital-based intrapartum care. RESULTS The number of hospitals offering birth services in Minnesota declined by 11% from 2011 to 2016. Moderate (>20-50 miles) and great (>50 miles) distances to nearest hospital-based intrapartum care were associated with increased odds of planned home birth compared with short distances (≤20 miles). Adjusted odds ratios were 3.31 (95% CI, 3.04-3.61) and 3.89 (95% CI, 2.37-6.37), respectively, after adjusting for maternal education, age, and race. Planned home birth was the intended birth setting in 4.3% of births among those living great distances from hospital-based intrapartum care, compared with 1.0% among those living a short distance from hospital-based intrapartum care. DISCUSSION Better understanding of how geographical barriers affect preferred birth settings can inform efforts to reduce the impact of hospital-based intrapartum service loss on rural women and their birth outcomes.

Abstract
The recurring association of specific genetic lesions with particular types of cancer is a fascinating and largely unexplained area of cancer biology. This is particularly true of clear cell renal cell carcinoma (ccRCC) where, although key mutations such as loss of VHL is an almost ubiquitous finding, there remains a conspicuous lack of targetable genetic drivers. In this study, we have identified a previously unknown protumorigenic role for the RUNX genes in this disease setting. Analysis of patient tumor biopsies together with loss-of-function studies in preclinical models established the importance of RUNX1 and RUNX2 in ccRCC. Patients with high RUNX1 (and RUNX2) expression exhibited significantly poorer clinical survival compared with patients with low expression. This was functionally relevant, as deletion of RUNX1 in ccRCC cell lines reduced tumor cell growth and viability in vitro and in vivo. Transcriptional profiling of RUNX1-CRISPR-deleted cells revealed a gene signature dominated by extracellular matrix remodeling, notably affecting STMN3, SERPINH1, and EPHRIN signaling. Finally, RUNX1 deletion in a genetic mouse model of kidney cancer improved overall survival and reduced tumor cell proliferation. In summary, these data attest to the validity of targeting a RUNX1-transcriptional program in ccRCC. SIGNIFICANCE: These data reveal a novel unexplored oncogenic role for RUNX genes in kidney cancer and indicate that targeting the effects of RUNX transcriptional activity could be relevant for clinical intervention in ccRCC.

Abstract
Objectives: This study examines the prevalence of exposure to adverse events and associations with stress levels among a diverse population-based sample of young people. The study further explores whether these vulnerable populations, who have the potential to benefit from the mind-body practice of yoga, engage in a regular yoga practice. Design: EAT 2018 (Eating and Activity over Time) is a population-based study in which survey data were collected from 1568 ethnically/racially diverse (81.2% nonwhite) emerging young adults (mean age: 22.0 ± 2.0 years). Results: Exposure to adverse events was highly prevalent. For example, 43.9% reported at least one adverse childhood experience (ACE) (e.g., physical, emotional, or sexual abuse before age 18), whereas 40.1% reported experiencing discrimination. Exposure to adverse events was associated with higher stress levels. Practicing yoga at least 30 min/week was reported by 12.7% of the population, with variation across sociodemographic characteristics. Young adults exposed to adverse events were either more or similarly likely to practice yoga than young adults not reporting adverse events. Conclusions: The high prevalence of exposure to adverse events and associations with higher levels of stress points to a need for public health interventions. Thus, it was promising to find that young people exposed to adverse events, who may have greater emotional burdens, practice yoga at equal or greater proportions to those without these exposures. Given the potential benefits of yoga for populations living with high stress, it is important to develop further outreach efforts and provide accessible, acceptable, and affordable opportunities for practicing yoga.

Abstract
International travel is popular worldwide, yet its implications for sexual and reproductive health are not fully understood. Few studies have examined the contextual factors that shape women's sexual and contraceptive behaviors-and thus, their risk of unintended pregnancy and sexually transmitted infections (STIs)-while traveling outside their home country. In this qualitative study, female university students with recent (n = 25) or upcoming (n = 19) travel outside the U.S. completed semi-structured interviews from October 2015 to March 2017. Transcripts were analyzed for themes related to contraceptive and sexual behaviors: (1) participants' pre-travel expectations of sex; (2) the circumstances surrounding sexual encounters with men while traveling; (3) negotiation about condom and contraception use with partners; and (4) factors affecting contraceptive adherence. Participants generally expected to be abstinent during travel, citing myriad rationales that included personal values, no perceived opportunities for sex, and the nature of the trip. Some travelers had unexpected sexual encounters, involving health-protecting behaviors and risk-taking (e.g., unprotected sex, substance use). New sexual partnerships were fueled by increased attention from men, situational disinhibition, and perceived heightened intimacy. International travel brought many contraceptive considerations (adequacy of supplies, access to refrigeration, time zone differences, etc.) as well as obstacles that triggered contraceptive lapses and discontinuation. Pill users described the most challenges, while travelers using intrauterine devices expressed appreciation for their maintenance-free contraception. This study suggests complex associations between international travel and young women's sexual and reproductive health. Some travelers were more vulnerable to situational risk factors, while others may have been more insulated. We identify potential intervention opportunities via clinical services, education, and policy to reduce young women's risk of adverse sexual and reproductive health outcomes while traveling abroad. We urge greater recognition of and conversations about contraceptive lapse and unintended pregnancy as potential health risks for female travelers of reproductive age, just as clinical guidelines acknowledge travel-associated STI.

Abstract
Epithelial to mesenchymal transition (EMT) is a dynamic process that drives cancer cell plasticity and is thought to play a major role in metastasis. Here we show, using MDA-MB-231 cells as a model, that the plasticity of at least some metastatic breast cancer cells is dependent on the transcriptional co-regulator CBFβ. We demonstrate that CBFβ is essential to maintain the mesenchymal phenotype of triple-negative breast cancer cells and that CBFβ-depleted cells undergo a mesenchymal to epithelial transition (MET) and re-organise into acini-like structures, reminiscent of those formed by epithelial breast cells. We subsequently show, using an inducible CBFβ system, that the MET can be reversed, thus demonstrating the plasticity of CBFβ-mediated EMT. Moreover, the MET can be reversed by expression of the EMT transcription factor Slug whose expression is dependent on CBFβ. Finally, we demonstrate that loss of CBFβ inhibits the ability of metastatic breast cancer cells to invade bone cell cultures and suppresses their ability to form bone metastases in vivo. Together our findings demonstrate that CBFβ can determine the plasticity of the metastatic cancer cell phenotype, suggesting that its regulation in different micro-environments may play a key role in the establishment of metastatic tumours.
