Abstinence beliefs in early adolescence and sexual risk behavior two years later.

INTRODUCTION: The United States has the highest teen pregnancy rate and sexually transmitted infection rates among developed countries. One common approach that has been implemented to reduce these rates is abstinence-only-until-marriage programs that advocate for delaying sexual intercourse until marriage. These programs focus on changing adolescents' beliefs toward abstinence until marriage; however, it is unclear whether adolescents' beliefs about abstinence predict their sexual behavior, including sexual risk behavior (SRB). An alternative approach may be encouraging youth to delay their sexual debut until they reach the age of maturity, but not necessarily until marriage. METHODS: To address this question, we compare the longitudinal association between abstinence beliefs (i.e., abstaining completely until marriage) and beliefs about delayed sexual debut with subsequent SRB 24 months later. The harmonized data set included 4620 (58.2% female, Mage = 13.0, SDage = 0.93) participants from three randomized controlled trials attending 44 schools in the southern United States. Negative binomial regressions were employed to examine the association of abstinence until marriage beliefs and beliefs regarding delaying sex with SRB. RESULTS: We identified that beliefs supporting delaying sex until an age of maturity were associated with lower odds of engaging in SRB, such as having multiple sex partners and frequency of condomless sex, for both sexes. However, stronger abstinence beliefs had no significant associations with all SRB outcomes. CONCLUSIONS: Findings suggest prevention programming that focuses on encouraging youth to delay sex until an appropriate age of maturity may be more effective at preventing SRB and consequent negative sexual health outcomes.

Sexual violence in early adolescence is associated with subsequent teen pregnancy and parenthood.

Being a victim of sexual violence (SV) is associated with risk for teen pregnancy in cross-sectional research. However, longitudinal data are necessary to determine if SV victimization plays a causal role in early pregnancy. To address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with pregnancy and having children by mid-adolescence. The current sample comprised 4594 youth (58% female; 51% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected via audio computer-assisted self-interview (ACASI) when students were in 7th or 8th grade and again approximately 24 months later. Approximately 2.9% of boys and 8.2% of girls reported SV victimization at baseline. At follow-up, 3.4% of boys and 4.0% of girls reported being involved with one or more pregnancies; 1.1% of boys and girls reported having one or more children. Being a victim of SV at baseline was associated with pregnancy and having a child at follow-up for girls. SV was not related to outcomes among boys. The present findings indicate that girls victimized by SV are at risk of becoming pregnant and becoming teen parents. The combined sequelae of SV and teen pregnancy impair health, economic, and social functioning across the lifespan and carry forward into future generations. Future research should explore mechanisms through which victimization confers risk for pregnancy to inform prevention strategies.

Who Benefits from School-Based Teen Pregnancy Prevention Programs? Examining Multidimensional Moderators of Program Effectiveness Across Four Studies.

Recent research has suggested the importance of understanding for whom programs are most effective (Supplee et al., 2013) and that multidimensional profiles of risk and protective factors may moderate the effectiveness of programs (Lanza & Rhoades, 2012). For school-based prevention programs, moderators of program effectiveness may occur at both the individual and school levels. However, due to the relatively small number of schools in most individual trials, integrative data analysis across multiple studies may be necessary to fully understand the multidimensional individual and school factors that may influence program effectiveness. In this study, we applied multilevel latent class analysis to integrated data across four studies of a middle school pregnancy prevention program to examine moderators of program effectiveness on initiation of vaginal sex. Findings suggest that the program may be particularly effective for schools with USA-born students who speak another language at home. In addition, findings suggest potential positive outcomes of the program for individuals who are lower risk and engaging in normative dating or individuals with family risk. Findings suggest potential mechanisms by which teen pregnancy prevention programs may be effective.

Examining Sex and Racial/Ethnic Differences in Co-use of Alcohol, Cannabis, and Cigarettes in a Community Sample of Adolescents.

INTRODUCTION: Although adolescents often co-use alcohol, cigarettes, and cannabis, little is known about sex and racial/ethnic differences in the co-use of these substances. Therefore, this investigation examined sex and racial/ethnic differences in alcohol, cigarette, and cannabis co-use in a large and ethnically diverse group. Methods: Participants were drawn from a large, multi-site study of adolescents from three regions in the United States (N = 4,129; Mage=16.10 years, SD = 0.59; 51% female, 49% male; 37% Black, 37% Hispanic, 25% White). Participants were categorized into eight mutually exclusive groups based on their self-reported use of alcohol, cannabis, and cigarettes in the last 30 days. Results: Unadjusted multinomial logistic regression revealed that males were more likely than females to use cannabis-only and to co-use all three substances. Additionally, Black and Hispanic adolescents were more likely to use cannabis-only, while White adolescents were more likely than Black and Hispanic adolescents to co-use alcohol and cigarettes. After adjusting for other sociodemographic variables (age, household income, parental education, and parent marital status), males were more likely to use cannabis-only than females; White youth were more likely than Hispanic youth to use cigarettes only and co-use cigarettes and alcohol. White youth were more likely than Black youth to co-use alcohol and cigarettes and co-use all three substances. Discussion: These results indicate sex and racial/ethnic differences in substance co-use that were not explained by socioeconomic factors. Results of this work suggest potential strategies for targeted prevention efforts and underscore the importance of continued efforts to better understand patterns of alcohol and substance co-use.

Violence exposure, affective style, and stress-induced changes in resting state functional connectivity.

Chronic childhood stress is linked to greater susceptibility to internalizing disorders in adulthood. Specifically, chronic stress leads to changes in brain connectivity patterns, and, in turn, affects psychological functioning. Violence exposure, a chronic stressor, increases stress reactivity and disrupts emotion regulation processes. However, it is unclear to what extent violence exposure affects the neural circuitry underlying emotion regulation. Individual differences in affective style also moderate the impact of stress on psychological function and can thus alter the relationship between violence exposure and brain function. Resting-state functional connectivity (rsFC) is an index of intrinsic brain activity. Stress-induced changes in rsFC between the amygdala, hippocampus, and prefrontal cortex (PFC) are associated with emotion dysregulation and may elucidate how affective style modulates the relationship between violence exposure and brain connectivity. Therefore, the present study examined the impact of violence exposure and affective style on stress-induced changes in rsFC. Participants (n = 233) completed two 6-minute resting-state functional magnetic resonance imaging scans, one before (pre-stress) and one after (post-stress) a psychosocial stress task. The bilateral amygdala, hippocampus, and ventromedial prefrontal cortex (vmPFC) were used as seed regions for rsFC analyses. Significant stress-induced changes in the prefrontal, fronto-limbic, and parieto-limbic rsFC were observed. Further, pre-stress to post-stress differences in rsFC varied with violence exposure and affective style. These findings suggest that prefrontal, fronto-limbic, and parieto-limbic connectivity is associated with the emotional response to stress and provide new insight into the neural mechanisms through which affective style moderates the impact violence exposure has on the brain.

Neighborhood Disorder, Family Functioning, and Risky Sexual Behaviors in Adolescence.

Adolescent risky sexual behaviors can result in negative consequences such as sexually transmitted infection. However, much research effort has been placed on understanding individual characteristics, rather than the role of neighborhood environment. This study addressed the prospective effects of neighborhood and family functioning in preadolescence on risky sexual behaviors. Participants included 4179 youth (Mage = 11.01 years, range 8.64-13.83; 51% female) and their caregivers. Using objective and self-reported measures of neighborhood and family functioning, results from multilevel regression analyses indicated that youth residing in disordered neighborhoods or had poorer family functioning in preadolescence were more likely to initiate sexual intercourse at younger ages 5 years later. Specifically, neighborhood poverty and decay were linked to early sexual initiation, whereas neighborhood social and family processes were protective against early sexual initiation. Males were more likely to engage in risky sexual behaviors in neighborhoods with greater poverty or decay; neighborhood poverty was linked with sexual initiation in White but not African American youth. Finally, parental monitoring moderated relationships between neighborhood social resources and contraceptive use, with neighborhood social resources linked with greater contraceptive use at low levels of parental monitoring, but lower contraceptive use at high levels of parental monitoring. These findings underscore the importance of neighborhood and family contexts in adolescents' risky sexual behavior, suggesting that males and White youth are more vulnerable to the effects of neighborhood poverty and that more research is needed on the possible counterproductive function of parental monitoring in neighborhoods with greater social resources.

Adolescent Dating Violence Prevention Program for Early Adolescents: The Me & You Randomized Controlled Trial, 2014-2015.

Objectives. To test the efficacy of Me & You, a multilevel technology-enhanced adolescent dating violence (DV) intervention, in reducing DV perpetration and victimization among ethnic-minority early adolescent youths. We assessed secondary impact for specific DV types and psychosocial outcomes.Methods. We conducted a group-randomized controlled trial of 10 middle schools from a large urban school district in Southeast Texas in 2014 to 2015. We used multilevel regression modeling; the final analytic sample comprised 709 sixth-grade students followed for 1 year.Results. Among the total sample, odds of DV perpetration were lower among intervention students than among control students (adjusted odds ratio = 0.46; 95% confidence interval = 0.28, 0.74). Odds of DV victimization were not significantly different. There were significant effects on some specific DV types.Conclusions. Me & You is effective in reducing DV perpetration and decreasing some forms of DV victimization in early middle-school ethnic-minority students.

Racial/ethnic disparities in health-related quality of life and health status across pre-, early-, and mid-adolescence: a prospective cohort study.

PURPOSE: To examine (1) racial/ethnic disparities in health-related quality of life (HRQOL) and overall health status among Black, Latino, and White youth during adolescence; (2) whether socioeconomic status (SES) and family contextual variables influence disparities; and (3) whether disparities are consistent from pre- to early- to mid-adolescence. METHODS: A population sample of 4823 Black (1755), Latino (1812), and White (1256) youth in three US metropolitan areas was prospectively assessed in a longitudinal survey conducted on three occasions, in 5th, 7th, and 10th grades, when youth reported their HRQOL using the PedsQL™ short-form Total, Physical and Psychosocial scales and youth and parents separately reported on youth's overall health status. Parents reported their education and household income to index SES, family structure, and use of English at home. RESULTS: Based on analysis conducted separately at each grade, marked racial/ethnic disparities were observed across all measures of HRQOL and health status, favoring White and disfavoring Black, and especially Latino youth. More strongly present in 5th and 7th grade, HRQOL disparities decreased by 10th grade. Most disparities between White and Black youth disappeared when adjusting for SES. However, even after adjusting for SES, family structure, and English use, overall health status disparities disfavoring Latino youth remained across all three assessments. CONCLUSIONS: Racial/ethnic disparities in adolescent HRQOL and health are substantial. These disparities appear consistent from pre- to early-adolescence but diminish for HRQOL by mid-adolescence. As disparities appear influenced by SES and other family contextual variables differently in different racial/ethnic groups, efforts to reduce health disparities in youth should address culturally specific conditions impinging on health.

Replication of It's Your Game Keep It Real! in Southeast Texas.

Despite the recent efforts of the Office of Adolescent Health to replicate programs with demonstrated efficacy, there are still few evidence-based HIV, sexually transmitted infection (STI), and teen pregnancy prevention programs that have been replicated in "real-world" settings. To test the effectiveness of It's Your Game…Keep It Real! (IYG), an evidence-based STI and pregnancy prevention program for middle schools, the curriculum was implemented by teachers in urban and suburban middle schools in Southeast Texas from 2012 to 2015. IYG was evaluated using a group-randomized wait-list controlled effectiveness trial design in which 20 middle schools in nine urban and suburban school districts in Southeast Texas were randomized equally, using a multi-attribute randomization protocol, to either the intervention condition (received IYG) (n = 10 schools comprising 1936 eligible seventh graders) or the comparison condition (received usual care) (n = 10 schools comprising 1825 eligible seventh graders). All students were blinded to condition prior to administering the baseline survey. The analytic sample comprised 1543 students (n = 804, intervention; n = 739, comparison) who were followed from baseline (seventh grade) to the 24-month follow-up (ninth grade). Multilevel regression analyses were conducted to assess behavioral and psychosocial outcomes at follow-up. There were no significant differences in initiation of vaginal or oral sex between study conditions at follow-up. However, at 12-month follow-up, compared with students in the comparison condition, students in the intervention condition reported increased knowledge, self-efficacy, and perceived favorable norms related to HIV/STIs, condoms, and/or abstinence; decreased intentions to have sex; and increased intentions to use birth control. Knowledge outcomes were statistically significant at 24-month follow-up. This IYG effectiveness trial did not replicate the behavioral effects of the original IYG efficacy trials. However, it adds to the growing literature on the replication of evidence-based programs, and underscores the need to better understand how variations in implementation, setting, and measurement affect the behavioral impact of such programs.Clinical trial registration clinicaltrials.gov (NCT03533192).

Perceived Physical Appearance: Assessing Measurement Equivalence in Black, Latino, and White Adolescents.

Objective: This aim of this study was to examine whether the construct of physical appearance perception differed among the three largest racial/ethnic groups in the United States using an adolescent sample. Methods: Black (46%), Latino (31%), and White (23%) adolescents in Grade 10 from the Healthy Passages study ( N = 4,005) completed the Harter's Self-Perception Profile for Adolescents-Physical Appearance Scale (SPPA-PA) as a measure of physical appearance perception. Results: Overall, Black adolescents had a more positive self-perception of their physical appearance than Latino and White adolescents. However, further analysis using measurement invariance testing revealed that the construct of physical appearance perception, as measured by SPPA-PA, was not comparable across the three racial/ethnic groups in both males and females. Conclusions: These results suggest that observed differences may not reflect true differences in perceptions of physical appearance. Measures that are equivalent across racial/ethnic groups should be developed to ensure more precise measurement and understanding.

iCHAMPSS: Usability and Psychosocial Impact for Increasing Implementation of Sexual Health Education.

INTRODUCTION: Diffusion of sexual health evidence-based programs (EBPs) in schools is a complex and challenging process. iCHAMPSS ( CHoosing And Maintaining effective Programs for Sex education in Schools) is an innovative theory- and Web-based decision support system that may help facilitate this process. The purpose of this study was to pilot-test iCHAMPSS for usability and short-term psychosocial impact. METHOD: School district stakeholders from across Texas were recruited ( N = 16) and given access to iCHAMPSS for 3 weeks in fall 2014. Pre- and posttests were administered to measure usability parameters and short-term psychosocial outcomes. Data were analyzed using descriptive statistics and the Wilcoxon signed-rank test. RESULTS: Most participants reported that iCHAMPSS was easy to use, credible, helpful, and of sufficient motivational appeal. iCHAMPSS significantly increased participants' self-efficacy to obtain approval from their board of trustees to implement a sexual health EBP. Positive, though nonsignificant, trends included increased knowledge to locate EBPs, skills to prioritize sexual health education at the district level, and ability to choose an EBP that best meets district needs. CONCLUSIONS: iCHAMPSS is an innovative decision support system that could accelerate uptake of EBPs by facilitating diffusion and advance the field of dissemination and implementation science for the promotion of sexual health EBPs.

Prevalence and Correlates of the Perpetration of Cyber Dating Abuse among Early Adolescents.

Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

Hippocampal gray matter volume in young adulthood varies with adolescent alcohol use.

Adolescent substance use is linked with negative future outcomes (e.g., depression, anxiety, substance use disorder). Given that the brain undergoes significant maturation during adolescence, this developmental period may represent a time of particular vulnerability to substance use. Neuroimaging research has largely focused on heavy or binge patterns of substance use; thus, relatively less is known about the neural impact of a broader range of adolescent substance use. Characterizing the neural impact of a broader range of adolescent substance use may inform prevention and treatment efforts. The present study investigated relationships between adolescent substance use trajectories (i.e., alcohol, tobacco, and cannabis) and gray matter volume in young adulthood. Substance use was assessed in 1,594 participants at ages 11, 13, 16, and 19. Following the last assessment, 320 participants completed a single magnetic resonance imaging session to assess brain gray matter volume. Latent growth curve models were used to estimate growth parameters characterizing alcohol, tobacco, and cannabis use trajectories for each participant. These growth parameters (i.e., intercept, linear slope, and quadratic slope) were then used as predictors of gray matter volume. The gray matter volume of the hippocampus was positively associated with age 14 alcohol use (i.e., intercept) but not other trajectories (i.e., progression or acceleration) or substances (tobacco or cannabis). These results provide new insight into the neural impact of distinct adolescent alcohol, tobacco, and cannabis use trajectories, which may help to refine prevention and treatment efforts.

Sexual Debut in Early Adolescence and Individual, School, and Neighborhood Social Capital.

PURPOSE: Sexual debut in early adolescence is associated with poor health outcomes in adulthood. We examined the associations of social capital within families, schools, and neighborhoods with early sexual debut. METHODS: Using data from the Healthy Passages cohort, a longitudinal multilevel study of adolescents, we performed a series of cross-classified multilevel logistic regression models to examine (1) the relative contribution of schools and neighborhoods to the variance and (2) the association of markers of social cohesion/social capital in families, schools, and neighborhoods with sexual debut by 10th grade. RESULTS: There were 4,001 youth participants nested in 115 schools and 751 neighborhoods, with a high degree of cross-classification (1,340 unique combinations of school and neighborhoods). In models adjusting for individual demographics, neighborhoods contributed more to the variance (log odds U [95% confidence interval {CI}] [intra class correlation {ICC}%]) in sexual debut than schools: Uneighborhoods = 0.11 (0.02, 0.23) [3.2%] versus Uschools = 0.07 (0.01, 0.16) [2%]. Restriction of dating and family cohesion, markers of family social capital, were associated with reduced odds of sexual debut by 10th grade (odds ratio = 0.45 95% CI: 0.41-0.49 and 0.93, 95% CI: 0.86, 1.00). Neighborhood cohesion and education level were associated with early debut. Although reduced, there remained significant, unexplained variance in both the school and neighborhood level in the fully adjusted model (Uschool = 0.08 [0.01, 0.17] [2.3%], Uneighborhood = 0.08 [0.02, 0.17] [2.2%]). DISCUSSION: Markers of social capital at the family and neighborhood levels were associated with sexual debut by 10th grade. Developers of public health programs aiming to delay sexual debut should consider family-focused and neighborhood-focused interventions.

Self-Efficacy to Refuse Sex Mediates the Relationship Between Dating Violence Victimization and Sexual Risk Behavior.

PURPOSE: While cross-sectional studies have shown that teen dating violence (TDV) victimization is linked to sexual risk behavior (SRB), the pathway between these variables is not well-understood. To address this knowledge gap, we explore the mediating role of self-efficacy to refuse sex in the longitudinal relationship between physical TDV victimization and subsequent SRB among adolescents. METHODS: Self-report data from three prior longitudinal studies were harmonized to create a single aggregated sample of primarily racial and ethnic minority adolescents (N = 4,620; 51.4% Hispanic, 38.5% Black, and 58% female) from 44 schools in the southwest U.S. Participants' physical TDV victimization at baseline (seventh and eighth grade), self-efficacy to refuse sex at 12-month follow-up, and SRB at 24-month follow-up was tested using mediation models with bias corrected bootstrapped confidence intervals. All regression models controlled for age, race, parental education, SRB at baseline, and intervention status. RESULTS: Physical TDV victimization at baseline was associated with refusal self-efficacy at 12 months and SRB (e.g., frequency of vaginal and oral sex, lifetime number of vaginal sex partners, and number of vaginal sex partners in the past three months without condom use) at 24 months. Refusal self-efficacy mediated the link between physical TDV victimization and increased risk of SRB for females and males, to a lesser extent. DISCUSSION: Adolescent victims of physical TDV report diminished self-efficacy to refuse sex, predisposing them to engage in SRBs, including condomless sex.

Economic Evaluation of an Intervention to Prevent Adolescent Dating Violence (Me & You).

Me & You: Building Healthy Relationships (Me & You) is a multilevel, technology-enhanced adolescent dating violence (DV) prevention program that aimed to reduce DV among ethnic-minority, early adolescent, urban youth. A group-randomized control trial of Me & You, conducted with 10 middle schools from a large urban school district in Southeast Texas in 2014-2015, found it to be effective in reducing DV perpetration and decreasing some forms of DV victimization. Economic evaluations of DV interventions are extremely limited, despite calls for more economic analyses to be incorporated in research. We help fill this gap by evaluating the cost-effectiveness from the payer and societal perspectives of implementing the Me & You program. Using cost data collected alongside the Me & You group-randomized trial, we computed incremental cost-effectiveness ratios. Our primary outcome was "any DV perpetrated" within 12 months of the intervention. We conducted a cost-benefit analysis beyond the intervention endpoint by using literature estimates of per-victim lifetime costs of DV. We performed sensitivity analyses to assess effects of uncertain parameters. Under the base-case scenario, the cost of the Me & You curriculum compared to the standard curriculum was $103.70 per-student from the societal perspective, and the effectiveness was 34.84 perpetrations averted, implying an incremental cost per perpetration averted of $2.98, which ranged from $0.48 to $73.24 in sensitivity analysis. Thus, we find the Me & You curriculum is cost-effective and cost-saving in most scenarios. Policymakers should carefully consider school-based DV prevention programs, and cost data should be regularly collected in adolescent prevention program evaluations.

The longitudinal association between sexual violence victimization and sexual risk behavior in adolescence.

Being a victim of sexual violence (SV) is generally believed to be associated with subsequent sexual risk behavior (SRB) during adolescence. While this assumption makes intuitive sense, it is based on methodologically limited research, including a reliance on cross-sectional data. To address this gap in research, we test whether experiencing SV victimization in early adolescence is associated with self-reported SRB approximately two years later. The sample comprised 4,618 youth (58% female; 52% Hispanic; 39% Black) attending 44 schools in the southern United States. Self-reported data were collected using an audio computer-assisted self-interview (ACASI). Baseline data were collected when students were in 7th or 8th grade and follow-up data were collected approximately 24 months later when students were in 9th or 10th grade. Indices of SRB included behaviors related to oral, vaginal, and anal sex (e.g., number of partners, number of times without a condom). Girls, but not boys, who reported SV victimization at baseline reported engaging more frequently in all oral and vaginal SRBs at 24 month follow-up compared to their non-victimized female counterparts. Additionally, girls reporting SV victimization reported more anal sex partners than non-victimized girls. Girls who are victims of SV engage in significantly more SRB by early high school placing them at greater risk to contract STIs and become pregnant. Victims of SV should be screened for SRB and provided access to the appropriate resources. Teen pregnancy and STI prevention planning should consider SV victimization in their strategy planning.

Stress-induced Changes in Autonomic Reactivity Vary with Adolescent Violence Exposure and Resting-state Functional Connectivity.

Exposure to violence during childhood can lead to functional changes in brain regions that are important for emotion expression and regulation, which may increase susceptibility to internalizing disorders in adulthood. Specifically, childhood violence exposure can disrupt the functional connectivity among brain regions that include the prefrontal cortex (PFC), hippocampus, and amygdala. Together, these regions are important for modulating autonomic responses to stress. However, it is unclear to what extent changes in brain connectivity relate to autonomic stress reactivity and how the relationship between brain connectivity and autonomic responses to stress varies with childhood violence exposure. Thus, the present study examined whether stress-induced changes in autonomic responses (e.g., heart rate, skin conductance level (SCL)) varied with amygdala-, hippocampus-, and ventromedial prefrontal cortex (vmPFC)-whole brain resting-state functional connectivity (rsFC) as a function of violence exposure. Two hundred and ninety-seven participants completed two resting-state functional magnetic resonance imaging scans prior to (pre-stress) and after (post-stress) a psychosocial stress task. Heart rate and SCL were recorded during each scan. Post-stress heart rate varied negatively with post-stress amygdala-inferior parietal lobule rsFC and positively with post-stress hippocampus-anterior cingulate cortex rsFC among those exposed to high, but not low, levels of violence. Results from the present study suggest that post-stress fronto-limbic and parieto-limbic rsFC modulates heart rate and may underlie differences in the stress response among those exposed to high levels of violence.

Evaluation of an Opioid-Free Anesthesia Protocol for Elective Abdominal Surgery in a Community Hospital.

Utilization of opioids for acute pain control during surgical procedures is commonplace for anesthesia providers. Opioid use is associated with many undesirable side effects, including opioid use disorder. Opioid-free anesthesia for surgical procedures using a multimodal approach can reduce these side effects. This quality improvement project evaluated the implementation of an opioid-free anesthesia protocol for elective abdominal surgical procedures in a community hospital. The project had specific aims of detecting a reduction in opioid consumption in the operating room and the first 30 minutes in the post anesthesia recovery unit (PACU) while confirming pain relief comparable to that seen with opioid analgesia. Implementation of the quality improvement protocol resulted in a 79% reduction in the number of patients who received opioids during surgery and provided pain relief through the first 30 minutes in PACU comparable to anesthesia that included opioids. This project confirmed that an opioid-free anesthesia protocol could be successfully implemented within a community hospital for healthy adults undergoing elective abdominal surgery.

Sex-related differences in violence exposure, neural reactivity to threat, and mental health.

The prefrontal cortex (PFC), hippocampus, and amygdala play an important role in emotional health. However, adverse life events (e.g., violence exposure) affect the function of these brain regions, which may lead to disorders such as depression and anxiety. Depression and anxiety disproportionately affect women compared to men, and this disparity may reflect sex differences in the neural processes that underlie emotion expression and regulation. The present study investigated sex differences in the relationship between violence exposure and the neural processes that underlie emotion regulation. In the present study, 200 participants completed a Pavlovian fear conditioning procedure in which cued and non-cued threats (i.e., unconditioned stimuli) were presented during functional magnetic resonance imaging. Violence exposure was previously assessed at four separate time points when participants were 11-19 years of age. Significant threat type (cued versus non-cued) × sex and sex × violence exposure interactions were observed. Specifically, women and men differed in amygdala and parahippocampal gyrus reactivity to cued versus non-cued threat. Further, dorsolateral PFC (dlPFC) and inferior parietal lobule (IPL) reactivity to threat varied positively with violence exposure among women, but not men. Similarly, threat-elicited skin conductance responses varied positively with violence exposure among women. Finally, women reported greater depression and anxiety symptoms than men. These findings suggest that sex differences in threat-related brain and psychophysiological activity may have implications for mental health.
