RESUMO

AIM: The U.S. resettlement program currently resettles refugees in communities of similar or the same ethnic background known as like-ethnic communities. This practice provides resettled refugees with a familiar community who may be able to provide support through the difficult resettlement process. However, by associating with a like-ethnic community, resettled refugees may limit interaction with the host community, which may have subsequent adverse effects on well-being. METHODS: This study examined whether satisfaction with community support is moderated by a premigration factor (trauma history) or a postmigration factor (English fluency) in predicting depressive symptoms in a resettled refugee community (N = 179). Four moderation models were analyzed and compared. RESULTS: The model in which English fluency moderated the relationship between satisfaction with community support and depressive symptoms had the best overall model fit. In addition, trauma history was found to also be a meaningful but secondary moderator within this relationship. English fluency and trauma history within this study did not significantly interact. CONCLUSION: These results highlight the importance of early English language lessons and community support during resettlement. Further, they emphasize the need to integrate refugees with individuals from similar backgrounds, as well as with host communities throughout resettlement.

RESUMO

BACKGROUND: Traumatic events experienced in childhood can lead to increased risk of cardiovascular disorders in adulthood. Black Americans are disproportionately affected, as they are at increased risk for experiencing childhood trauma and cardiovascular diseases in adulthood. One of the hypothesized mechanisms of this association is through long-lasting dysregulation of the autonomic nervous system, a hallmark physiological biomarker of posttraumatic stress disorder (PTSD), which is twice as prevalent in women compared to men. METHODS: Ninety-one, majority Black American children, aged 9 were recruited to be a part of our longitudinal study of child development at research centers in Atlanta, GA and Detroit, MI. Resting HR was measured through a electrocardiogram (ECG) recording using the Biopac MP150. Self-report measures of violence exposure and PTSD symptoms were administered by research staff. RESULTS: Children with more violence exposure reported increased PTSS as well as lower resting HR. Regression analysis showed evidence of sex modifying this relationship, (B = -0.64, p < 0.05), such that the association between resting HR and PTSS was stronger in girls than in boys. In our exploratory analysis with standard clinical cutoffs of resting HR, the normative HR group was found to significantly moderate the relationship between violence exposure and PTSS in boys, (B = -2.14, p < 0.01), but not girls (B = -0.94, p = 0.27). CONCLUSION: In our sample of primarily Black urban children, we found that violence exposure was associated with slower, more adult-like HR, that girls showed greater PTSS associated with slower HR while boys did not, and that girls with lower than normative HR showed significantly higher PTSS compared to girls with normative HR. Our sample's demonstration of psychological consequences in addition to the physiological implications could provide new information about a psychobiological sequelae of violence exposure.


Experiencing traumatic events in childhood can lead to increased risk of heart disease in adulthood. One of the ways this might happen is through long-lasting changes of the autonomic nervous system. This system is dysregulated in posttraumatic stress disorder (PTSD), which is twice as common in women compared to men. We explored whether resting heart rate (HR), a measure of autonomic functioning was associated with violence exposure in children, and whether this relationship was different in boys and girls. We also explored whether categorizing our sample into resting HR groups based off standardized norms for HR predicted differing relationships between violence exposure and posttraumatic stress symptoms (PTSS). Because childhood trauma and heart disease impact Black Americans at greater rates, we recruited our sample of 92 nine-year-old children from research centers in Atlanta, GA and Detroit, MI. We measured their resting HR, exposure to violence, and PTSS. We found that violence exposure was associated with lower HR overall, that girls showed greater PTSS associated with lower HR when compared to boys, and that boys with lower than normative HR showed a stronger association between violence exposure and PTSS compared to boys with normative HR. Future studies should examine potential mechanisms underlying this sex difference to best understand the long-term cardiovascular consequences for sex-related health disparities. Specifically, longitudinal studies may be able to help researchers understand how reduced HR during adolescents might lead to future cardiovascular disease and psychopathology.

RESUMO

Although many children experience trauma, few receive diagnoses and subsequent care despite experiencing trauma-related sequelae. At age nine (M = 9.11), children (N = 62; female = 46.4%) who predominantly identified as Black (78.7%) were enrolled in this first study examining how skin conductance as captured by mobile technology, eSense, related to children's traumatic experiences and trauma-related symptoms. Skin conductance measures were associated with degree of trauma exposure and PTSD hyperarousal symptoms. These findings suggest that physiological responses in addition to self-report measures may be easily used to assess children's trauma exposure and symptoms. Given eSense's ease-of-use, this technology could assist clinics and research institutions assess children's trauma-related needs.

RESUMO

BACKGROUND: Cross-sectional studies have found that individuals with posttraumatic stress disorder (PTSD) exhibit deficits in autonomic functioning. While PTSD rates are twice as high in women compared to men, sex differences in autonomic functioning are relatively unknown among trauma-exposed populations. The current study used a prospective design to examine sex differences in posttraumatic autonomic functioning. METHODS: 192 participants were recruited from emergency departments following trauma exposure (Mean age = 35.88, 68.2% female). Skin conductance was measured in the emergency department; fear conditioning was completed two weeks later and included measures of blood pressure (BP), heart rate (HR), and high frequency heart rate variability (HF-HRV). PTSD symptoms were assessed 8 weeks after trauma. RESULTS: 2-week systolic BP was significantly higher in men, while 2-week HR was significantly higher in women, and a sex by PTSD interaction suggested that women who developed PTSD demonstrated the highest HR levels. Two-week HF-HRV was significantly lower in women, and a sex by PTSD interaction suggested that women with PTSD demonstrated the lowest HF-HRV levels. Skin conductance response in the emergency department was associated with 2-week HR and HF-HRV only among women who developed PTSD. CONCLUSIONS: Our results indicate that there are notable sex differences in autonomic functioning among trauma-exposed individuals. Differences in sympathetic biomarkers (BP and HR) may have implications for cardiovascular disease risk given that sympathetic arousal is a mechanism implicated in this risk among PTSD populations. Future research examining differential pathways between PTSD and cardiovascular risk among men versus women is warranted.
