RESUMO

Although the high prevalence of intimate partner violence (IPV) in Haiti is well-documented, its association with post-traumatic stress disorder (PTSD) symptoms among adolescents and young adults remains unexplored. Using a representative sample of adolescents and young adults from rural and urban areas across the 10 geographical regions of Haiti, this study investigates the association between IPV and PTSD symptoms. It explores the role of social support, emotion regulation, other traumatic events, and sociodemographic factors. The sample consisted of 3,586 participants, of whom 43.21 % (1,538) reported being in a dating relationship in the past year (56.04 % women). Overall, 25.53 % of the participants were categorized as having probable PTSD. Results showed that participants who experienced at least one episode of IPV victimization presented a higher prevalence of PTSD (32.28 %) compared to those who did not have any experience (16.29 %), χ2 (1) = 44.83, p < .001. The logistic regression model showed that emotional IPV, sexual IPV, traumatic life events, emotional dysregulation, and social support were associated with PTSD symptoms. This study highlights a strong association between IPV and PTSD symptoms, as well as factors that can contribute to the development and implementation of prevention and intervention programs among adolescents and young adults in Haiti.

RESUMO

OBJECTIVE: Despite evidence that Black individuals are confronted with various types of racial discrimination that put them at risk for alcohol and substance use disorders, no study in Canada has assessed the frequency and factors related to substance use in Black communities. This study thus aims to examine the frequency and factors related to substance use in Black communities in Canada. METHOD: A total of 845 Black individuals in Canada (76.6% female) completed questionnaires assessing substance use (i.e., alcohol, cannabis, and other drugs), everyday racial discrimination, resilience, religious involvement, and sociodemographic information. Multivariable regression analyses were used to determine factors related to substance use among Black individuals. RESULTS: The findings showed that 14.8% (95% CI [8.60, 20.94]) of participants reported using any substance (i.e., alcohol, cannabis, and other drugs) in the past 12 months. Men reported a significantly higher frequency of substance use than women (25.7% vs. 11.1%; x² = 27.67, p < .001). Everyday racial discrimination (ß = .27, p < .001) and place of birth (born in Canada, ß = .14, p < .001) were positively associated with substance use, whereas it was negatively associated with religiosity, resilience, and gender (being a female; ß = -.08, p < .05; ß = -.21, p < .001; ß = -.12, p < .001). CONCLUSIONS: Racial discrimination is associated with substance use among Black individuals in Canada. The study findings inform potential prevention and intervention strategies by examining protective factors related to substance use (e.g., religiosity, resilience, gender) among Black individuals.

RESUMO

Very little is known in Haiti and the Caribbean regarding child and lifetime sexual victimization. Using a nationally representative sample of adolescents and young adults aged 15-24, this study aimed to document the prevalence, risk factors and mental health correlates of lifetime and child sexual violence in Haiti. A national cross-sectional surrvey was conducted in Haiti, using a multistage sampling frame, stratified by geographical department, urban or rural setting, gender, and age groups (15-19 and 20-24 years). The final sample included 3586 household participants (47.6% female). A weighted sample of 3945 individuals was obtained and used in the following analyses. Overall rate of lifetime and child sexual violence was, respectively, 27.44% (95% CI 25.94-28.94) and 11.27% (95% CI 10.18-12.35). Lifetime sexual violence rate was significantly higher among female participants (29.02%; 95% CI 27.5-30.55) compared to male (25.73%, 95% CI 24.26-27.2), χ2 = 4.63, p < .05, but there was no significant gender difference for child sexual victimization. Experiences of family physical violence, emotional abuse by mother and father, divorce of parents, and other physical violence were strongly associated with higher odds of sexual victimization. Participants who reported having experienced sexual violence are more at risk to meet criteria of PTSD (OR = 1.96, 95% CI 1.66-2.32; p < .0001), depression (OR = 1.73, 95% CI 1.47-2.02; p < .0001), psychological distress (OR =1.72, 95% CI 1.47-2.02; p < .0001), and substance abuse (OR = 1.33, 95% CI 1.13-1.57; p < .0001). Findings demonstrate that sexual violence is a public health emergency in Haiti. They provide evidence for the development of prevention and intervention programs.

RESUMO

OBJECTIVE: Most Black individuals in Canada report having experienced racial discrimination. Although previous studies have shown that there is a strong relationship between racial discrimination and posttraumatic stress disorder (PTSD), no studies in Canada have documented this association among Black individuals. The present study documents (1) the prevalence of PTSD among Black individuals using data from the Black Communities Mental Health project and (2) risk factors associated with PTSD, including racial microaggressions, everyday racial discrimination, and internalized racism. METHOD: A total of 860 participants (75.6% of women) aged 15 to 40 years old (M = 24.96, SD = 6.29) completed questionnaires assessing PTSD, experience of traumatic events, racial microaggressions, everyday racial discrimination, and internalized racism. RESULTS: Findings showed that 95.1% of participants reported exposure to at least one traumatic event during their lifetime. In total, 67.11% of participants reported probable PTSD with no significant difference between men and women (68.2% and 67.8%, χ2 = 0.132, p = 0.72). Participants born in Canada were more likely to experience significant PTSD symptoms, compared to those born abroad (70.92% and 53.14%, χ2 = 19.69, p < 0.001). A multivariable linear regression model of PTSD symptoms was computed using sociodemographic variables and exposure to traumatic events as independent variables, which explained 25.9% of the variance. In addition to these variables, a second model included racial microaggressions, everyday racial microaggressions, and internalized racism, which explained 51.8% of the variance. The model showed that traumatic events (b = 0.6; p = 0.02), racial microaggressions (b = 0.5; p < 0.001), everyday discrimination (b = 0.2; p = 0.03) and internalized racism (b = 0.5; p < 0.001) were positively associated with PTSD symptoms. CONCLUSIONS: This article highlights the detrimental consequences of racial discrimination against Black people in Canada. Prevention and mental health programs aimed at mitigating its consequences on the lives of Black people and other racialized populations must be implemented.

RESUMO

On-site experiences and reports have shown that the multiple outbreaks of Ebola virus disease (EVD) in the Democratic Republic of the Congo (DRC) resulted in pervasive experience of stigma against many people who have recovered from EVD as well as their families and close relatives. Three evidence-based protective factors which are supposed to mitigate the impact of enacted Ebola stigma on health-related quality of life (HRQoL) of individuals in this epidemic context were identified. We expected that positive religious coping, perceived social support, and general self-efficacy would mediate the relationship between enacted Ebola stigma and HRQoL. These hypotheses were tested through multiple mediation model using the structural equation modeling among a large sample of adult populations (N = 1614; 50% women) in the province of Equateur in the DRC, in the aftermath of the 9th Ebola outbreak. The mediation model yielded adequate fit statistics and the results provided strong evidence that higher levels of enacted Ebola stigma were associated with lower HRQoL. They confirmed the synergetic mediating effects of positive religious coping, perceived social support from family (but not from others sources) and general self-efficacy. Futher exploratory findings revealed that the perceived social support from family buffered the impact of enacted Ebola stigma on HRQoL. If replicated by a longitudinal study, our findings lay a solid foundation for empirical-based community mental health interventions for reducing enacted Ebola stigma and promoting HRQoL during epidemics, especially in the DRC.

RESUMO

Ebola virus disease (EVD) survivors and healthcare workers (HCWs) face stress, fear, and stigma during the COVID-19 pandemic that can induce severe symptoms of anxiety and post-traumatic stress disorder (PTSD). We examined the prevalence and factors related to severe PTSD and anxiety symptoms, using a representative sample of survivors of the 2018-2020 EVD epidemic in DR Congo in comparison HCWs. Five hundred sixty-three participants (55.25% women, 309 survivors, 202 HCWs, and 52 HCWs and survivors) completed questionnaires assessing anxiety, PTSD, exposure to EVD and COVID-19, stigmatization related to EVD and COVID-19, interpersonal traumas, social support. During the COVID-19 pandemic, 45.6 and 75.0% of survivors and HCWs reported severe symptoms of PTSD and anxiety. Significant difference was observed among the three groups for both PTSD (53.7% survivors, 37.1% HCWs, and 30.8% HCWs-survivors, χ2= 18.67, p < 0.0001) and anxiety (88.3% survivors, 56.9% HCWs, and 65.4% HCWs- survivors, χ2= 67.03, p < 0.0001). Comorbidity of severe PTSD and anxiety symptoms was 42.3% between the three groups. Results revealed that exposure to EVD (b = 0.53; p = 0.001; b = 0.12; p = 0.042), EVD-related stigmatization (b = 0.14; p = 0.018; b = 0.07; p = 0.006), COVID-19-related stigmatization (b = 0.22; p < 0.0001; b = 0.08; p = 0.0001) and social support (b = -0.30; p < 0.0001; b = -0.14; p < 0.0001) predicted severe PTSD and anxiety symptoms. The last models explained 63.8 and 56.4% of the variance of PTSD and anxiety. Symptoms of PTSD and anxiety are common among EVD survivors and HCWs during the COVID-19 pandemic. Culturally-sensitive programs that address stigma are necessary to mitigate the cumulative effects of EVD and the COVID-19 pandemic on EVD survivors and HCWs.

RESUMO

OBJECTIVE: Anxiety disorders are highly prevalent worldwide but vary significantly by country and ethnoracial background. Minimal published data exist on the prevalence of clinically significant anxiety among Black people in Canada and none using validated measures. Therefore, this study sought to establish the frequency of clinically significant anxiety symptoms among a sample of Black people living in Canada as well as examine the association with two forms of racism (racial discrimination and racial microaggressions). METHODS: Data collected from the Black Community Mental Health project in Canada was analyzed. Participants provided (N= 845) sociodemographic information and completed measures assessing anxiety symptomology (GAD-7), everyday racial discrimination, racial microaggressions, and resilience. Prevalence of anxiety symptomatology was determined across sociodemographic variables as well as categories of everyday racial discrimination and racial microaggressions. Two regression models were conducted to examine the relationship between anxiety symptoms and the two forms of racism controlling for sociodemographic factors. RESULTS: Overall, nearly a third of participants endorsed clinically significant levels of anxiety symptoms, with higher rates observed among men, unemployed people, those with higher education, people who are separated, and those with no reported family history of mental health problems. Logistic regression models demonstrated that, except for those reporting the greatest frequency of racial discrimination, there is a general linear trend such that those experiencing higher levels of racial discrimination or racial microaggressions are increasingly more likely to present with anxiety symptoms when compared to those reporting low levels of discrimination or microaggressions. Psychological resilience afforded nominal protection but only against exposure to racial microaggressions. CONCLUSIONS: Rates of clinically significant anxiety are higher among Black people in Canada than reported previously. Both racial discrimination and racial microaggressions predicted higher rates of anxiety symptoms. The results are discussed in relation to previous findings from the US that report similar findings.

RESUMO

OBJECTIVES: Black Canadians report experiencing various forms of racial discrimination disproportionately. This study aimed to: (a) examine the association between everyday racial discrimination and self-esteem; (b) test the mediating role of internalized racism and social support in the association between racial discrimination and self-esteem, and (c) test the moderating role of gender and age in this same relationship. METHOD: A total of 860 participants (76.60% female) aged 15-40 (Mage = 24.96, SD = 6.31) completed questionnaires assessing racial discrimination, self-esteem, internalized racism, and social support. Descriptive and moderated mediation analyses were performed. RESULTS: A total of 65.33% of participants were categorized as endorsing low self-esteem, with no significant difference between males and females (66.67% and 62.20%, respectively; χ² = 1.56, p = .47). Participants aged 25-40 exhibited a higher prevalence of low self-esteem compared to those aged 15-24 (89.91% and 58.54%, respectively, χ² = 37.31, p < .001). The results showed a progressive increase in the prevalence of low self-esteem commensurate with increasing levels of reported racial discrimination. Internalized racism (ß = -.09, SE = .01, p < .001) and social support (ß = .10, SE = .01, p < .001) mediated the association between everyday racial discrimination and self-esteem; whereas gender moderated the latter association (ß = .17, SE = .04, p < .001; being a woman). CONCLUSIONS: Results indicate a strong association between racial discrimination and low self-esteem. These findings provide a better understanding of the mechanisms underlying the development of self-esteem problems among Black individuals in Canada. They also have important relevance for the development of educational and clinical programs for prevention and intervention. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

RESUMO

BACKGROUND: Studies examining both victimization and perpetration of dating violence among both women and men are virtually non-existent in Haiti. This study aimed to document the prevalence and factors associated with victimization and perpetration of dating violence (DV) among adolescents and young adults aged 15-24 years in Haiti. PARTICIPANTS AND SETTING: A total of 3586 participants (47.6% women; mean age = 19.37; SD = 2.71) were sampled in the 10 geographical departments according to residence areas (urban/rural), age group (15-19/20-24 years old), and gender (men/women). METHOD: Participants completed questionnaires assessing DV victimization and perpetration, witnessing interparental violence, parental violence, violence acceptance, social desirability, and self-esteem. RESULTS: Overall, 1538 participants (56% women) were in a romantic relationship in the past year. Results showed that men were more likely to experience both psychological (49.4% of women and 57% of men, X2 = 8.17, p = .004), and physical violence (11.1% of women and 18.8% of men, X2 = 8.13, p = .004). There were marginally significant differences for sexual violence between gender for adolescents aged 15 to 19 (26.5% of girls and 20.5% of boys, X2 = 3.25, p = .07), and not for young adults (21.8% of women and 24.0% of men, X2 = 0.49, p = .48). No significant difference was observed for any forms of DV perpetration. DV perpetration was positively associated with victimization (b = 0.5, p = .002), however victimization was not associated with perpetration. Results also showed different associations between violence perpetration and victimization, gender, social desirability, acceptance of violence, parental violence, and witnessing interparental violence. CONCLUSIONS: This study highlights avenues for prevention and intervention that must begin at an early age, engage teachers, train peer-educators, promote healthy, non-violent and egalitarian romantic relationships.

RESUMO

OBJECTIVES: High mortality rates, anxiety and distress associated with Ebola virus disease (EVD) are risk factors for mood disorders in affected communities. This study aims to document the prevalence and risk factors associated with depressive symptoms among a representative sample of individuals affected by EVD. DESIGN: Cross-sectional study. SETTING: The current study was conducted 7 months (March 11, 2019 to April 23, 2019) after the end of the ninth outbreak of EVD in the province of Equateur in the Democratic Republic of the Congo (DRC). PARTICIPANTS: A large population-based sample of 1614 adults (50% women, Mage=34.05; SD=12.55) in health zones affected by the ninth outbreak in DRC. PRIMARY AND SECONDARY OUTCOME MEASURES: Participants completed questionnaires assessing EVD exposure level, stigmatisation related to EVD and depressive symptoms. The ORs associated with sociodemographic data, EVD exposure level and stigmatisation were analysed through logistic regressions. RESULTS: Overall, 62.03% (95% CI 59.66% to 64.40%) of individuals living in areas affected by EVD were categorised as having severe depressive symptoms. The multivariable logistic regression analyses showed that adults in the two higher score categories of exposure to EVD were at two times higher risk of developing severe depressive symptoms (respectively, OR 1.94 (95% CI 1.22 to 3.09); OR 2.34 (95% CI 1.26 to 4.34)). Individuals in the two higher categories of stigmatisation were two to four times more at risk (respectively, OR 2.42 (95% CI 1.53 to 3.83); OR 4.73 (95% CI 2.34 to 9.56)). Living in rural areas (OR 0.19 (95% CI 0.09 to 0.38)) and being unemployed (OR 0.68 (95% CI 0.50 to 0.93)) increased the likelihood of having severe depressive symptoms. CONCLUSIONS: Results indicate that depressive symptoms in EVD affected populations is a major public health problem that must be addressed through culturally adapted mental health programs.

RESUMO

The prevalence and correlates of different forms of racial discrimination among Black Canadians are unknown. This article aims to examine the prevalence of different forms of racial discrimination (daily, major and microaggressions) and their association with self-esteem and satisfaction with life among Black Canadians. A convenience sample of 845 Black Canadians aged 15-40 was recruited. We assessed frequencies of everyday and major racial discrimination, and racial microaggressions against Black Canadians and their association with self-esteem and satisfaction with life, controlling for gender, age, job status, education, and matrimonial status. At least 4 out of 10 participants declared having being victims of everyday racial discrimination at least once per week. Between 46.3% and 64.2% of participants declared having been victims of major racial discrimination in various situations including education, job hiring, job dismissal, health services, housing, bank and loans, and police encounters. Significant gender differences were observed for everyday and major racial discrimination with higher frequencies among female participants. A total of 50.2% to 93.8% of participants declared having been victims of at least one episode of racial microaggressions. Results showed a significant negative association between racial discrimination and satisfaction with life (b = -0.26, p = .003), and self-esteem (b = -0.23, p = .009). This study highlights the need to stop colorblind policies in different sectors in Canada, and for a public commitment to combat racism at the municipal, provincial and federal levels. Implications are discussed for prevention, research and public health.

RESUMO

Respiratory monitoring, using impedance with implanted telemetry in socially housed animals, was not possible until the recent development of digital signal transmission. The objective of this study was to evaluate digital telemetry monitoring of cardiopulmonary parameters (respiratory rate, tidal volume, minute volume, electrocardiography (DII), systemic arterial blood pressure, physical activity, and body temperature) in conscious, single-housed, non-rodent species commonly used in toxicology studies following administration of positive/negative controls (saline, dexmedetomidine, morphine, amphetamine, and doxapram), and also, the effects of various social housing arrangements in untreated female and/or male cynomolgus monkeys, Beagle dogs, and Göttingen minipigs (n = 4 per species). Aggressions were observed in socially housed male minipigs, however, which prevented pair-housed assessments in this species. All tested pharmacological agents significantly altered more than one organ system, highlighting important inter-organ dependencies when analyzing functional endpoints. Stress-related physiological changes were observed with single-housing or pair-housing with a new cage mate in cynomolgus monkeys and Beagle dogs, suggesting that stable social structures are preferable to limit variability, especially around dosing. Concomitant monitoring of cardiovascular and respiratory parameters from the same animals may help reduce the number of animals (3 Rs) needed to fulfill the S7A guidelines and allows for identification of organ system functional correlations. Globally, the data support the use of social housing in non-rodents for safety pharmacology multi-organ system (heart and lungs) monitoring investigations.

RESUMO

Few instruments assess community resilience. In the midst of the COVID-19 pandemic, the capacity of communities to support resilience of members deserves to be assessed to develop programs for improving mental health of affected populations. This article presents the development of the Ottawa-Community Resilience Scale (O-CRS), its underlying factorial structure and transcultural validity with a multilingual (English, French, Creole, Kinyarwanda), multinational (DR Congo, Haiti, Rwanda, Togo) and multicultural sample affected by this pandemic. A sample of 1,267 participants (40.9% women) were recruited in the four countries: DRC (n = 626, 43.4% women), Haiti (n = 225, 42.0% women), Rwanda (n = 174, 40.5% women), and Togo (n = 242, 33.2% women), with a mean age of 32 (SD = 10.1). They completed measures assessing individual resilience, depression and the O-CRS. Exploratory and confirmatory Factor Analyses, Cronbach alpha, coefficient H and the McDonald's Omega, and bivariate regression were used to estimate the underlying components of the O-CRS, its internal consistency and concurrent validity. Parallel factorial analysis and confirmatory factor analysis results revealed an excellent fit 3-factor structure. Internal consistency coefficients varied between 0.82 and 0.95. The O-CRS showed a good construct validity with a positive association with individual resilience and negative association with depression score. Developed with a collaborative approach involving researchers, practitioners, and clients/patients, the O-CRS and its three factors (community strengths and support, community trust and faith, and community values) demonstrated excellent psychometric properties for assessing community resilience among adults during the COVID-19 pandemic.

RESUMO

BACKGROUND: Mechanisms worsening the development of Posttraumatic stress disorder (PTSD) symptoms among individuals affected by high-mortality epidemics are unclear. This study examined the prevalence of PTSD and related risk factors among populations affected by the Ebola virus disease (EVD) outbreak, and investigated whether peritraumatic distress mediates the impact of exposure level to EVD on PTSD symptoms, and the moderation role of stigmatization. METHODS: The sample included 1614 participants (50% women) affected by EVD in Democratic Republic of the Congo (DRC). Participants completed the PTSD Check-List for DSM-5, Peritraumatic Distress Inventory, and measures evaluating levels of exposure and stigmatization related to EVD. Descriptive analyses and a moderated mediation model were computed. RESULTS: A total of 58.81% participants (95% CI: 56.41%; 61.21%) met PTSD diagnostic criteria. Participants living in rural areas presented greater risk, while there is no significant difference between men and women. Peritraumatic distress mediated partially the association between exposure to EVD and PTSD symptoms. Moreover, this relationship was moderated by stigmatization related to EVD. LIMITATIONS: As the design was cross-sectional, this study could not examine the causality of PTSD symptoms among communities affected by EVD. CONCLUSIONS: This study shows high prevalence rates and important risk factors associated with PTSD in populations affected by EVD. It indicates elements that could help to develop and implement prevention and intervention programs in affected communities.

RESUMO

BACKGROUND: Depression is a common mental health problem causing significant disability globally, including in Canada. Prevalence estimates for depression within Black communities in Canada are unknown. This study determined the prevalence of depression in a sample of Black Canadians and the association between everyday racial discrimination experiences and depression. METHODS: We analyzed data collected from the Black Community Mental Health project in Canada. Participants provided sociodemographic information and completed measures assessing depressive symptomology, everyday racial discrimination, and social support. The prevalence of depressive symptomatology was computed across sociodemographic variables and categories of everyday racial discrimination. Different regression models were conducted to examine the relationship between depressive symptoms and everyday racism controlling for sociodemographic factors. RESULTS: In total, 65.87% of participants reported severe depressive symptoms, with higher rates among women, those who are employed, and those born in Canada. The linear regression models showed that everyday racial discrimination is the best predictor of depressive symptoms, with a final model explaining 25% of the variance. A logistic regression model demonstrated that those experiencing a high level of racial discrimination are 36.4 more likely to present severe depressive symptoms when compared to those reporting a low level of discrimination. CONCLUSIONS: Rates of depressive symptoms among Black individuals are nearly six times the 12-month prevalence reported for the general population in Canada. Racial discrimination, which significantly predicts greater depressive symptomatology, is consistent with earlier studies in the United States and suggests that Canadian colorblind policies may inadvertently reinforce racial discrimination with detrimental effects on mental health.

RESUMO

OBJECTIVES: Currently, there is little data on the mental health consequences of the COVID-19 pandemic in low- and middle-income countries (LMICs). This study aims to examine the pooled and separate prevalence and determinants of depression during the pandemic in samples from four LMICs. METHODS: Participants (N= 1267, 40.9% women) were recruited from the Democratic Republic of the Congo (DRC), Haiti, Rwanda, and Togo. They completed an online cross-sectional survey on sociodemographics, exposure and stigmatization related to COVID-19, the Hopkins Symptom Checklist depression subscale, and the Connor-Davidson Resilience Scale-2. RESULTS: The pooled prevalence for depression symptoms was 24.3% (95% CI: 22.08-26.79%), with significant differences across countries. Younger age, gender (women), and high levels of exposure and stigmatization related to COVIID-19, and resilience were associated with depression in the pooled data. There were significant variations at the country level. Stigmatization (but not exposure to COVID-19 and resilience) was a strong predictor among the four countries. CONCLUSIONS: The prevalence of depression symptoms in the LMICs are similar to those reported in China and in most high-income countries during the pandemic. The findings emphasize the need for implementing non-fear-based education programs during epidemics to reduce stigmatization.

RESUMO

PURPOSE: Ebola virus disease (EVD) is associated with high anxiety and multiple bereavement that can induce severe psychological distress (SPD) in individuals living in affected communities. Using data from the EVD and Mental Health project (EboMH), this study assessed the prevalence and determinants of SPD symptoms in a representative sample of adults in communities affected by EVD. METHODS: A representative sample of 1614 adults (50% women) aged 18-85 years completed measures assessing exposure level to EVD, stigmatization related to EVD, and psychological distress. RESULTS: In total, 45.58% of individuals from the cities and villages affected by EVD reported SPD. Results showed significant differences for residence area, employment, age, education level, and religion, but not for gender. Exposure level to EVD (ß = 0.11, p < 0.001; OR = 1.12, 95% CI [1.08-1.16]), stigmatization related to EVD (ß = 0.06, p < 0.001; OR = 1.06, 95% CI [1.05-1.07]), and living in rural areas (ß = 0.67, p < 0.001; OR = .51, 95% CI [.36-.72]) predicted SPD symptoms. CONCLUSIONS: Evidence-based global mental health programs in high-risk mortality epidemic contexts should take into account the high psychological distress in the affected areas.

RESUMO

OBJECTIVE: Studies have documented the significant direct and indirect psychological, social, and economic consequences of the Coronavirus disease 2019 (COVID-19) in many countries but little is known on its impact in low- and middle-income countries (LMICs) already facing difficult living conditions and having vulnerable health systems that create anxiety among the affected populations. Using a multinational convenience sample from four LMICs (DR Congo, Haiti, Rwanda, and Togo), this study aims to explore the prevalence of anxiety symptoms and associated risk and protective factors during the COVID-19 pandemic. METHODS: A total of 1267 individuals (40.8% of women) completed a questionnaire assessing exposure and stigmatization related to COVID-19, anxiety, and resilience. Analyses were performed to examine the prevalence and predictors of anxiety. RESULTS: Findings showed a pooled prevalence of 24.3% (9.4%, 29.2%, 28.5%, and 16.5% respectively for Togo, Haiti, RDC, and Rwanda, x2 = 32.6, p < .0001). For the pooled data, exposure to COVID-19 (ß = 0.06, p = .005), stigmatization related to COVID-19 (ß = 0.03, p < .001), and resilience (ß = -0.06, p < .001) contributed to the prediction of anxiety scores. Stigmatization related to COVID-19 was significantly associated to anxiety symptoms in all countries (ß = 0.02, p < .00; ß = 0.05, p = .013; ß = 0.03, p = .021; ß = 0.04, p < .001, respectively for the RDC, Rwanda, Haiti, and Togo). CONCLUSIONS: The findings highlight the need for health education programs in LMICs to decrease stigmatization and the related fears and anxieties, and increase observance of health instructions. Strength-based mental health programs based on cultural and contextual factors need to be developed to reinforce both individual and community resilience and to address the complexities of local eco-systems.

RESUMO

INTRODUCTION: Corrected QT (QTc) interval is an essential proarrhythmic risk biomarker, but recent data have identified limitations to its use. The J to T-peak (JTp) interval is an alternative biomarker for evaluating drug-induced proarrhythmic risk. The aim of this study was to evaluate pharmacological effects using spatial magnitude leads and DII electrocardiogram (ECG) leads and common ECG confounders (ie, stress and body temperature changes) on covariate adjusted QT (QTca), covariate adjusted JTp (JTpca), and covariate adjusted T-peak to T-end (Tpeca) intervals. METHODS: Beagle dogs were exposed to body hyper- (42 °C) or hypothermic (33 °C) conditions or were administered epinephrine to assess confounding effects on heart rate corrected QTca, JTpca, and Tpeca intervals. Dofetilide (0.1, 0.3, 1.0 mg/kg), ranolazine (100, 140, 200 mg/kg), and verapamil (7, 15, 30, 43, 62.5 mg/kg) were administered to evaluate pharmacological effects. RESULTS: Covariate adjusted QT (slope -12.57 ms/°C) and JTpca (-14.79 ms/°C) were negatively correlated with body temperature but Tpeca was minimally affected. Epinephrine was associated with QTca and JTpca shortening, which could be related to undercorrection in the presence of tachycardia, while minimal effects were observed for Tpeca. There were no significant ECG change following ranolazine administration. Verapamil decreased QTca and JTpca intervals and increased Tpeca, whereas dofetilide increased QTca and JTpca intervals but had inconsistent effects on Tpeca. CONCLUSION: Results highlight potential confounders on QTc interval, but also on JTpca and Tpeca intervals in nonclinical studies. These potential confounding effects may be relevant to the interpretation of ECG data obtained from nonclinical drug safety studies with Beagle dogs.
