Failure to detect tuberculosis in Black lechwe antelopes (Kobus leche smithemani) in Zambia

<p>Abstract</p> <p>Background</p> <p>Two types of lechwe antelopes exclusively exist in their natural ecosystems in Zambia; the Black lechwe (<it>Kobus leche smithemani</it>) and the Kafue lechwe (<it>Kobus leche kafuensis</it>). Despite inhabiting similar ecosystems, tuberculosis has been reported in Kafue lechwe without its documentation in Black lechwe antelopes. However, the past few decades have seen a drastic decline in both lechwe populations. Whereas studies have postulated that infectious diseases such as tuberculosis are having a negative impact on the Kafue lechwe population, no information is available on Black lechwe antelopes. Thus this study was conducted to investigate tuberculosis in Black lechwe antelopes of the Bangweulu swamps in comparison with the Kafue lechwe antelopes of Lochinvar.</p> <p>Findings</p> <p>A total of 44 lechwe antelopes (Black (<it>n </it>= 30): Kafue (<it>n </it>= 14) were sampled from Bangweulu and Lochinvar respectively. A positive case was defined with findings of gross lesions with Ziehl Nielsen and culture confirmation. Out of the 14 animals examined in Lochinvar, 21.4% [95% CI: 15.4, 44.4%] had necropsy lesions consistent with tuberculosis. The corresponding samples from 30 Black lechwe of Bangweulu yielded negative results on all the three tests.</p> <p>Conclusions</p> <p>Current findings from this study intimate the possible absence of tuberculosis in Black lechwe antelopes whilst confirming the presence of tuberculosis in Kafue lechwe of the Kafue basin. The absence of tuberculosis in the Black lechwe suggests that the observed population decline may not be caused by tuberculosis. However, without detailed molecular epidemiological studies it is not possible to determine the association of <it>M. bovis </it>infection in sympatric animal populations. The possible role of transmission of tuberculosis between wildlife and cattle is discussed herein. <b>Findings</b></p

Support for Texting-Based Condom Negotiation Among Forcibly Displaced Adolescents in the Slums of Kampala, Uganda: Cross-sectional Validation of the Condom Use Negotiated Experiences Through Technology Scale

BackgroundPromoting sexual health among forcibly displaced adolescents is a global public health priority. Digital sexual communication strategies (eg, sexting) may increase adolescents’ confidence in discussing sexual health issues and negotiating condom use. However, limited evidence exists describing validated measures for text-based condom negotiation in the literature. ObjectiveThis study helps fill this gap by adapting and examining the psychometric properties of a condom use experience through technology (condom use negotiated experiences through technology [CuNET]) scale. MethodsUsing peer network sampling, 242 forcibly displaced adolescents (aged 16-19 years) living in Kampala’s slums were recruited for participation between January and March 2018. A subscale (embarrassment to negotiate condom use) of the Multidimensional Condom Attitudes Scale was adapted to incorporate sexting, yielding CuNET. Participants were randomly assigned to calibration and validation subsamples to conduct exploratory and confirmatory factor analyses to establish and validate the scale. CuNET measured participants’ support levels for texting-based condom negotiation via sexting based on gender, and multivariable logistic regression was used to explore its associations with sexual health outcomes (recent consistent condom use, access to sexual and reproductive health services, and lifetime sexually transmitted infection testing). ResultsThe one-factor CuNET with the validation sample was valid (χ24=5.3; P=.26; root mean square error of approximation=0.05, 90% CI 0.00-0.16; comparative fit index=0.99; Tucker-Lewis index=0.99; standardized root mean square residual=0.006), and reliability (Cronbach α=.98). Adolescent girls showed significantly lower levels of support for using sexting to negotiate condom use (mean 13.60, SE 0.70 vs mean 21.48, SE 1.23; P=.001). In multivariable analyses, a 1-point increase in the CuNET score was associated with increased odds of recent consistent condom use (adjusted odds ratio [aOR] 1.73, 95% CI 1.24-2.41) but not with access to sexual and reproductive health services (aOR 1.51, 95% CI 0.99-2.30) or lifetime sexually transmitted infection testing (aOR 0.90, 95% CI 0.64-1.26). ConclusionsThe unidimensional CuNET scale is valid and reliable for forcibly displaced adolescents living in slums in Kampala, gender-sensitive, and relevant for predicting consistent condom use among urban displaced and refugee adolescents. Further development of this scale will enable a better understanding of how adolescents use digital tools for condom negotiation

Contextual factors associated with depression among urban refugee and displaced youth in Kampala, Uganda: findings from a cross-sectional study

Background: Advancing mental health among refugee and displaced adolescents and youth is critically important, as chronic psychological stress can have lifelong harmful impacts. These groups experience socio-environmental stressors that can harm mental health. Informed by a social contextual framework, this study explored the prevalence of depression among urban refugee and displaced youth in Kampala, Uganda and associations with symbolic (violence), relational (social support), and material (food and community insecurity) contexts. Methods: We implemented a cross-sectional survey with refugee and displaced adolescent girls and young women and adolescent boys and young men aged 16–24 living in Kampala’s informal settlements. We conducted peer-driven recruitment, whereby peer navigators shared study information with their networks and in turn participants were invited to recruit their peers. We conducted gender disaggregated analyses, including stepwise multiple regression to examine factors associated with depression. We then conducted structural equation modeling (SEM) using weighted least squares estimation to examine direct paths from violence, food insecurity, and community insecurity to depression, and indirect effects through social support. Results: Among participants (n = 445), young women (n = 333) reported significantly higher depression symptoms than young men (n = 112), including any symptoms (73.9% vs. 49.1%, p < 0.0001), mild to moderate symptoms (60.4% vs. 45.5%, p = 0.008), and severe symptoms (13.5% vs 3.6%, p = 0.002). SEM results among young women indicate that the latent violence factor (lifetime sexual and physical violence) had direct effects on depression and social support, but social support did not mediate the path from violence to depression. The model fit the data well: χ2(3) = 9.82, p = 0.020; RMSEA = 0.08, 90% CI [0.03, 0.14], CFI = 0.96). Among young men, SEM findings indicate that food insecurity had direct effects on social support, and an indirect effect on depression through the mediating role of social support. Fit indices suggest good model fit: χ2(3) = 2.09, p = 0.352; RMSEA = 0.02, 90% CI [0.000, 0.19], CFI = 0.99. Conclusions: Findings reveal widespread depression among urban refugee and displaced youth in Kampala, disproportionately impacting young women. Contextual factors, including food insecurity and violence, increase depression risks. Strategies that reduce gender-based violence and food insecurity, and increase social support networks, have the potential to promote mental health among urban refugee and displaced youth.The study was funded by the Canadian Institutes of Health Research.

Exploring resource scarcity and contextual influences on wellbeing among young refugees in Bidi Bidi refugee settlement, Uganda: findings from a qualitative study

Background: Contextual factors including poverty and inequitable gender norms harm refugee adolescent and youths’ wellbeing. Our study focused on Bidi Bidi refugee settlement that hosts more than 230,000 of Uganda’s 1.4 million refugees. We explored contextual factors associated with wellbeing among refugee adolescents and youth aged 16–24 in Bidi Bidi refugee settlement. Methods: We conducted 6 focus groups (n = 3: women, n = 3: men) and 10 individual interviews with young refugees aged 16–24 living in Bidi Bidi. We used physical distancing practices in a private outdoor space. Focus groups and individual interviews explored socio-environmental factors associated with refugee youth wellbeing. Focus groups were digitally recorded, transcribed verbatim, and coded by two investigators using thematic analysis. Analysis was informed by a social contextual theoretical approach that considers the interplay between material (resource access), symbolic (cultural norms and values), and relational (social relationships) contextual factors that can enable or constrain health promotion. Results: Participants included 58 youth (29 men; 29 women), mean age was 20.9 (range 16–24). Most participants (82.8%, n = 48) were from South Sudan and the remaining from the Democratic Republic of Congo (17.2% [n = 10]). Participant narratives revealed the complex interrelationships between material, symbolic and relational contexts that shaped wellbeing. Resource constraints of poverty, food insecurity, and unemployment (material contexts) produced stress and increased sexual and gender-based violence (SGBV) targeting adolescent girls and women. These economic insecurities exacerbated inequitable gender norms (symbolic contexts) to increase early marriage and transactional sex (relational context) among adolescent girls and young women. Gendered tasks such as collecting water and firewood also increased SGBV exposure among girls and young women, and this was exacerbated by deforestation. Participants reported negative community impacts (relational context) of COVID-19 that were associated with fear and panic, alongside increased social isolation due to business, school and church closures. Conclusions: Resource scarcity produced pervasive stressors among refugee adolescents and youth. Findings signal the importance of gender transformative approaches to SGBV prevention that integrate attention to resource scarcity. These may be particularly relevant in the COVID-19 pandemic. Findings signal the importance of developing health enabling social contexts with and for refugee adolescents and youth.This work was supported by Grand Challenges Canada’s Stars in Sexual and Reproductive Health and Rights fund (grant number R-ST-POC-1908-26653).

Examining the substance use, violence, and HIV and AIDS (SAVA) syndemic among urban refugee youth in Kampala, Uganda: cross-sectional survey findings

BACKGROUND: Interactions between substance use, violence, HIV and AIDS, known as the ‘SAVA’ syndemic, are understudied among refugee youth. We assessed the synergistic effects of frequent alcohol use, depression and violence on HIV vulnerability among urban refugee youth aged 16–24 years in Kampala, Uganda. METHODS: We conducted a cross-sectional survey between January and April 2018 with a convenience sample of refugee youth aged 16–24 years living in informal settlements in Kampala (Kabalagala, Rubaga, Kansanga, Katwe, Nsambya). We assessed non-communicable health conditions (frequent [≥3 times per week] alcohol use [FAU]; depression); violence (young adulthood violence [YAV] at age ≥16 years, intimate partner violence [IPV]), and HIV vulnerability (past 12-month transactional sex; recent [past 3-month] multiple [≥2] sex partners). We calculated the prevalence and co-occurrence of non-communicable health conditions, violence and HIV vulnerability variables. We then conducted multivariable logistic regression analyses to first create unique profiles of FAU, depression, YAV and IPV exposures, and second to assess for interactions between exposures on HIV vulnerability outcomes. RESULTS: Most participants (n=445; mean age: 19.59, SD: 2.6; women: n=333, 74.8%, men: n=112, 25.2%) reported at least one non-communicable health condition or violence exposure (n=364, 81.8%), and over half (n=278, 62.4%) reported co-occurring exposures. One-fifth reported FAU (n=90; 20.2%) and one-tenth (n=49; 11%) major depression. In logistic regression models including all two-way product terms, adjusted for sociodemographics, we found (a) multiplicative interaction for joint effects of FAU and IPV (adjusted OR (aOR)=4.81, 95% CI: 1.32 to 17.52) on multiple sex partners, and (b) multiplicative interaction for joint effects of FAU and IPV (aOR=3.72, 95% CI: 1.42 to 9.74), and YAV and depression (aOR=7.13, 95% CI: 1.34 to 37.50), on transactional sex. CONCLUSION: Findings signal the importance of addressing the SAVA syndemic among urban refugee youth in Uganda. Synergistic interactions indicate that addressing FAU, depression or violence may concomitantly reduce HIV vulnerability with urban refugee youth

Mixed-methods findings from the Ngutulu Kagwero (agents of change) participatory comic pilot study on post-rape clinical care and sexual violence prevention with refugee youth in a humanitarian setting in Uganda

There is a dearth of evidence-based post-rape clinical care interventions tailored for refugee adolescents and youth in low-income humanitarian settings. Comics, a low-cost, low-literacy and youth-friendly method, integrate visual images with text to spark emotion and share health-promoting information. We evaluated a participatory comic intervention to increase post-exposure prophylaxis (PEP) knowledge and acceptance, and prevent sexual and gender-based violence, in Bidi Bidi refugee settlement, Uganda. Following a formative qualitative phase, we conducted a pre-test post-test pilot study with refugee youth (aged 16–24 years) (n = 120). Surveys were conducted before (t0), after (t1), and two-months following (t2) workshops. Among participants (mean age: 19.7 years, standard deviation: 2.4; n = 60 men, n = 60 women), we found significant increases from t0 to t1, and from t0 to t2 in: (a) PEP knowledge and acceptance, (b) bystander efficacy, and (c) resilient coping. We also found significant decreases from t0 to t1, and from t0 to t2 in sexual violence stigma and depression. Qualitative feedback revealed knowledge and skills acquisition to engage with post-rape care and violence prevention, and increased empathy to support survivors. Survivor-informed participatory comic books are a promising approach to advance HIV prevention through increased PEP acceptance and reduced sexual violence stigma with refugee youth.

Social ecological factors associated with experiencing violence among urban refugee and displaced adolescent girls and young women in informal settlements in Kampala, Uganda: a cross-sectional study

Abstract Background Research on violence targeting urban forcibly displaced adolescent girls and young women (AGYW) is limited, particularly regarding polyvictimization (exposure to multiple forms of violence). Yet there is a global trend of refugee urbanization, and urban AGYW are at the nexus of violence disparities among adolescents, forcibly displaced persons, and slum dwellers. This study explored factors associated with young adulthood violence (> 16 years) (YAV) and intimate partner violence (IPV) among forcibly displaced AGYW in Kampala, Uganda. Methods We conducted a cross-sectional survey with forcibly displaced AGYW aged 16–24 from five informal settlement (slum) communities across Kampala (Kabalagala, Rubaga, Kansanga, Katwe, Nsambya) using peer network sampling. We assessed YAV (experienced at age 16 or above) (sexual, physical, emotional violence) and recent (past 12-month) IPV (physical, sexual, control violence). We conducted descriptive statistics, followed by multinomial logistic regression analyses to explore social ecological factors (e.g., intrapersonal: depression; interpersonal: sexual relationship power, community: food insecurity) associated with experiencing YAV and YAV polyvictimization, and IPV and IPV polyvictimization. Results Over half of participants (n = 333; mean age = 19.31; SD = 2.56, range = 16–24) reported YAV (n = 179; 53.7%) and 9.3% (n = 41) reported YAV polyvictimization. Most participants that were in an intimate relationship in the last 12 months (n = 200; 85.8%) reported IPV, among these, 45.5% reported one form of IPV and 54.5% reported IPV polyvictimization. In adjusted analyses, experiencing any YAV was significantly associated with: adolescent sexual and reproductive health (SRH) stigma; sexual relationship power; mobile app usage; depressive symptoms; childhood abuse; and childhood polyvictimization. In adjusted analyses YAV polyvictimization was associated with: depressive symptoms; childhood polyvictimization; sexual relationship power; and food insecurity. Recent IPV polyvictimization in adjusted analyses was associated with owning/using a mobile phone and depressive symptoms. Participants with higher sexual relationship power had lower odds of recent IPV polyvictimization. Conclusion Findings suggest that YAV and IPV polyvictimization require urgent attention among forcibly displaced AGYW in Kampala. Multi-level strategies are required to address intrapersonal e.g. (depression), interpersonal (e.g. childhood abuse, sexual relationship power) and community (e.g. adolescent SRH stigma, food insecurity) factors associated with experiencing violence. Future research can tailor approaches to advance health, agency and human rights among urban forcibly displaced AGYW

The role of context in shaping HIV testing and prevention engagement among urban refugee and displaced adolescents and youth in Kampala, Uganda: findings from a qualitative study

OBJECTIVE: To explore experiences, preferences and engagement with HIV testing and prevention among urban refugee and displaced adolescents and youth in Kampala, Uganda, with a focus on the role of contextual factors in shaping access and uptake. METHODS: This qualitative community‐based study with urban refugee and displaced youth aged 16–24 living in Kampala’s informal settlements involved five focus groups (FG), including two with young women, two with young men, and one with sex workers from March to May 2019. We also conducted five in‐depth key informant interviews. We conducted thematic analysis informed by Campbell and Cornish’s conceptualisation of material and symbolic contexts. RESULTS: Refugee/displaced youth participants (n = 44; mean age: 20.25, SD: 2.19; men: n = 17; women: n = 27) were from the Democratic Republic of Congo (n = 29), Rwanda (n = 11), Burundi (n = 3) and Sudan (n = 1). Participant narratives reflected material and symbolic contexts that shaped HIV testing awareness, preferences and uptake. Material contextual factors that presented barriers to HIV testing and prevention engagement included transportation costs to clinics, overcrowded living conditions that limited access to private spaces, low literacy and language barriers. Symbolic contexts that constrained HIV testing engagement included medical mistrust of HIV testing and inequitable gender norms. Religion emerged as an opportunity to connect with refugee communities and to address conservative religious positions on HIV and sexual health. CONCLUSION: Efforts to increase access and uptake along the HIV testing and prevention cascade can meaningfully engage urban refugee and displaced youth to develop culturally and contextually relevant services to optimise HIV and sexual health outcomes

We examined associations between stigma (HIV-related and adolescent sexual and reproductive health [SRH]-related) and HIV testing services awareness and HIV testing uptake among urban refugee and displaced youth in Kampala, Uganda. We implemented a cross-sectional survey with refugee and displaced adolescent girls and young women (AGYW) and adolescent boys and young men (ABYM) aged 16-24. We conducted exploratory and confirmatory factor analysis of an adolescent SRH stigma scale and identified a two-factor structure ("Sexual activity & pregnancy stigma","Modern family planning & abortion stigma"). We conducted multivariable logistic regression analysis to determine the adjusted risk ratio for HIV testing services awareness and testing uptake. Among participants (n=445; mean age=19.59, SD=2.60; AGYW: n=333; 74.7%), two-thirds were aware of HIV testing services in their community and over half (56.0%) had received a lifetime HIV test. In adjusted multivariable regression analysis findings with AGYW: (a) higher sexual activity & pregnancy stigma and modern family planning & abortion stigma were associated with reduced odds of HIV testing services awareness, and (b) modern family planning & abortion stigma was associated with reduced lifetime HIV testing odds. Stigma was not associated with HIV testing awareness/uptake among ABYM. HIV testing services awareness among AGYW was lower than among ABYM, yet AGYW were more likely to have been tested and to experience adolescent SRH stigma as a testing barrier. Addressing adolescent SRH stigma may optimise AGYW's HIV testing

Intersecting stigma and HIV testing practices among urban refugee adolescents and youth in Kampala, Uganda: qualitative findings

Introduction: HIV-related risks may be exacerbated in humanitarian contexts. Uganda hosts 1.3 million refugees, of which 60% are aged under 18. There are knowledge gaps regarding HIV testing facilitators and barriers, including HIV and intersecting stigmas, among urban refugee youth. In response, we explored experiences and perspectives towards HIV testing strategies, including HIV self-testing, with urban refugee youth in Kampala, Uganda. Methods: We implemented a qualitative study with refugee cisgender youth aged 16 to 24 living in Kampala's informal settlements from February-April 2019. We conducted five focus groups with refugee youth, including two with adolescent boys and young men, two with adolescent girls and young women and one with female sex workers. We also conducted five key informant (KI) interviews with government, non-government and community refugee agencies and HIV service providers. We conducted thematic analyses to understand HIV testing experiences, perspectives and recommendations. Results: Participants (n = 49) included young men (n = 17) and young women (n = 27) originally from the Democratic Republic of Congo [DRC] (n = 29), Rwanda (n = 11), Burundi (n = 3) and Sudan (n = 1), in addition to five KI (gender: n = 3 women, n = 2 men; country of origin: n = 2 Rwanda, n = 2 Uganda, n = 1 DRC). Participant narratives revealed stigma drivers included fear of HIV infection; misinformation that HIV is a “Ugandan disease”; and blame and shame for sexual activity. Stigma facilitators included legal precarity regarding sex work, same-sex practices and immigration status, alongside healthcare mistreatment and confidentiality concerns. Stigma experiences were attributed to the social devaluation of intersecting identities (sex work, youth, refugees, sexual minorities, people living with HIV, women). Participants expressed high interest in HIV self-testing. They recommended HIV self-testing implementation strategies to be peer supported and expressed concerns regarding sexual- and gender-based violence with partner testing. Conclusions: Intersecting stigma rooted in fear, misinformation, blame and shame, legal precarity and healthcare mistreatment constrain current HIV testing strategies with urban refugee youth. Findings align with the Health Stigma and Discrimination Framework that conceptualizes stigma drivers and facilitators that devalue intersecting health conditions and social identities. Findings can inform multi-level strategies to foster enabling HIV testing environments with urban refugee youth, including tackling intersecting stigma and leveraging refugee youth peer support.Canadian Institutes of Health Research Project Grant.
