RESUMO

Fasciolosis is a zoonosis that limits the productivity of ruminants worldwide, but there is a lack of information on its occurrence in Burundi. Therefore, this study aimed to fill the information gap by determining the prevalence and risk factors associated with bovine fasciolosis in the Imbo Region of Burundi. Two prevalence studies were conducted in parallel in the five communes of the five provinces in the Imbo region. In the first study, a total of 426 fecal samples were collected from randomly selected cattle farms and microscopically examined to determine Fasciola egg burden. Survey data on cattle husbandry were collected from owners of these cattle and analyzed to determine the risk factors for bovine fasciolosis. In the second study, 467 cattle were randomly selected in abattoirs and their livers were examined postmortem to determine liver fluke burdens. Data were entered separately into Microsoft Excel and analyzed using R software. The overall prevalence of bovine fasciolosis was 47.7% (42.9-52.4, 95% CI) for microscopic examination and 33.2% (28.9-37.5, 95% CI) for postmortem examinations. The majority of positive cattle (60.6%) had light intensity infections as determined by eggs per gram of feces (epg). Postmortem examinations corroborated these results and indicated that 80% of cattle had light intensity infections. Chi-square analysis showed a statistical association with the presence of bovine fasciolosis and the age, sex, and origin of cattle and the practices of cattle owners (P < 0.05).

RESUMO

OBJECTIVE: To evaluate a family- and church-based intervention for adolescents and caregivers in rural Kenya to improve family relationships, reduce HIV risk, and promote mental health. METHOD: The intervention was developed using community-based participatory methods and focused on strengthening family communication. Modules addressed economic, relationship, and HIV-related topics using evidence-based behavioral strategies alongside culturally grounded content. A stepped wedge cluster randomized trial was conducted with 124 families (237 adolescents ages 10 to 16; 203 caregivers) from 4 churches. Participants completed interviewer-administered surveys over 5 rounds. Primary outcomes included family communication, HIV risk knowledge, self-efficacy, and beliefs. Secondary outcomes included parenting, social support, mental health, and adolescent sexual behavior. We estimated intent-to-treat effects via ordinary least squares regression with clustered standard errors. RESULTS: Relative to controls, the intervention group reported better family communication across domains at 1- and 3-months postintervention and higher self-efficacy for risk reduction skills and HIV-related knowledge at 1-month postintervention. Sexually active youth in the intervention reported fewer high-risk behaviors at 1-month postintervention, including unprotected sex or multiple partners. Male caregivers in the intervention reported higher parental involvement at both time points, and youth reported more social support from male caregivers at 3-months postintervention. No effects on secondary outcomes of parenting, social support, and mental health were detected. CONCLUSIONS: This intervention holds promise for strengthening positive family processes to protect against negative future outcomes for adolescents. Implementation with religious congregations may be a promising strategy for improving sustainability and scalability of interventions in low-resource settings. (PsycINFO Database Record

RESUMO

Community-Based Participatory research (CBPR) introduces new ethical challenges for HIV prevention studies in low-resource international settings. We describe a CBPR study in rural Kenya to develop and pilot a family-based HIV prevention and mental health promotion intervention. Academic partners (APs) worked with a community advisory committee (CAC) during formative research, intervention development, and a pilot trial. Ethical challenges emerged related to: negotiating power imbalances between APs and the CAC; CAC members' shifting roles as part of the CAC and wider community; and anticipated challenges in decision making about sustainability. Factors contributing to ethical dilemmas included low access to education, scarcity of financial resources, and the shortage of HIV-related services despite high prevalence.

RESUMO

OBJECTIVE: To examine orphan status, mental health, social support, and HIV risk among adolescents in rural Kenya. METHODS: Randomly selected adolescents aged 10-18 years completed surveys assessing sexual activity, sex-related beliefs and self-efficacy, mental health, social support, caregiver-child communication, time since parental death, and economic resources. Analysis of covariance and regression analyses compared orphans and nonorphans; orphan status was tested as a moderator between well-being and HIV risk. RESULTS: Orphans reported poorer mental health, less social support, and fewer material resources. They did not differ from nonorphans on HIV risk indicators. Longer time since parental death was associated with poorer outcomes. In moderator analyses, emotional problems and poorer caregiver-youth communication were more strongly associated with lower sex-related self-efficacy for orphans. CONCLUSIONS: Orphans are at higher risk for psychosocial problems. These problems may affect orphans' self-efficacy for safer sex practices more than nonorphans. Decreased HIV risk could be one benefit of psychosocial interventions for orphans.

RESUMO

In this study, we explored how adolescents in rural Kenya apply religious coping in sexual decision-making in the context of high rates of poverty and Human Immunodeficiency Virus (HIV). Semi-structured interviews were conducted with 34 adolescents. One-third (13) reported religious coping related to economic stress, HIV, or sexual decision-making; the majority (29) reported religious coping with these or other stressors. Adolescents reported praying for God to partner with them to engage in positive behaviors, praying for strength to resist unwanted behaviors, and passive strategies characterized by waiting for God to provide resources or protection from HIV. Adolescents in Sub-Saharan Africa may benefit from HIV prevention interventions that integrate and build upon their use of religious coping.

RESUMO

INTRODUCTION: HIV patients have reduced immune response which makes them more susceptible to different infections. This cross-sectional study was carried out to document the prevalence of intestinal parasites among HIV patients in Baringo County, Kenya. METHODS: Structured questionnaires were used to collect clinical information after obtaining consent from the participants. Stool samples were collected from 285 respondents for intestinal parasitic examination using direct and formol-ether concentration to detect ova and cysts. Chi-square (X(2)) statistical analysis was used to test level of significance at P = 0.05 using SPSS. RESULTS: A prevalence of 50.9% of intestinal parasites was recorded. Majority of the parasitic infections were waterborne protozoa with few helminthes. There was an association (P < 0.05) between intestinal parasitic infection and place of residence, agro-ecological location, family size, water source, treatment and reliability and diarrheal status. There was no association (P > 0.05) between age groups and gender with parasitic infection. Parasites identified were Entamoeba histolytica/dispar (58.3%), Giardia lamblia (16.6%), Ascaris lumbricoides (8.6%), Entamoeba coli (5.9%), Taenia saginata (5.3%), Trichuris trichuria (1.9%), Enterobius vermicularis (1.9%) and hookworm (1.3%). CONCLUSION: There was high prevalence of intestinal parasites, therefore, health education to HIV patients and community health workers on the importance of good environmental sanitation and personal hygiene could curb water, food and individual contamination promoting good management and care of HIV patients, hence improving their health status.

RESUMO

Associations between individual- and family-level psychosocial factors and sexual behavior were examined among 325 adolescents ages 10-18 in rural Kenya. History of sexual activity was reported by 51% of males and 30% of females. Among those reporting sex within the past year, 64% of males and 32% of females had multiple partners; 85% of males and 54% of females reported not using a condom at last sex. Multivariate logistic regression modeling demonstrated sexually active adolescents were significantly more likely to be older, male, more accepting of risky behavior, and have greater perceived HIV risk, caregiver social support, social support related to HIV, and emotional problems. Youths reporting high-risk behavior (unprotected sex or multiple partners) were significantly more likely to be younger, male, and have lower sex-related self-efficacy, lower caregiver monitoring, and more externalizing problems. Future studies should evaluate HIV prevention interventions targeting improvements in mental health and family relationships.
