ABSTRACT
BACKGROUND: Sexually transmitted infections (STIs) cause adverse health outcomes, including increasing HIV acquisition/transmission risk. We analyzed data from an HIV biomarker and behavioral survey to estimate STI prevalence, and explore associated factors in the setting of a generalized HIV epidemic in Siaya County, western Kenya. METHODS: Data were collected in March-September 2022 through face-to-face interviews using structured questionnaires; records from 9643 sexually active participants aged 13+ years were included in the analysis. We calculated weighted self-reported STI prevalence, by sex, age, and HIV status and explored associated factors using multivariable logistic regression. RESULTS: Median age was 37 years and 59.9% were female; HIV prevalence was 18.0%. Overall STI prevalence was 1.8%; 1.5-fold higher among males vs. females, and 2.6-fold higher among participants living with HIV vs. those without. HIV status and multiple sexual partners were independently associated with STI in both sexes. Mind-altering substance use and being circumcised were associated with STI among males. CONCLUSIONS: This study estimates STI prevalence in the setting of high HIV prevalence. Findings underscore the importance of: effective STI screening in HIV clinics and HIV testing and counseling in STI clinics; screening and counseling on substance use, and HIV pre-exposure prophylaxis; and intensive sexual health counseling in male circumcision programmes.

PURPOSE: Youth aged 15-19 years and parents of minors aged 15-17 years in sub-Saharan Africa are under-represented in empirical consent research. Thus, knowledge is limited concerning the adequacy of consent procedures and need for strategies to improve consent comprehension among these groups. We assessed comprehension following standard consent procedures and evaluated an enhanced procedure among Kenyan youth and parents. METHODS: Participants were adolescents aged 15-17 years (n = 273), their parents (n = 196), and young adults aged 18-19 years (n = 196). We used a quasi-experimental cohort design to implement standard and enhanced (single condition: extended discussion, test/feedback) consent procedures. Participants completed a 21-item informed consent comprehension assessment instrument. RESULTS: After standard consent procedures, mean comprehension scores were 11.36, 13.64, and 13.43 (score range: 0-21) among adolescents, young adults, and parents, respectively. About 6.2% of adolescents, 19.6% of young adults, and 21.4% of parents answered ≥ 80% of the questions correctly. After the enhanced procedures, comprehension scores (15.87 adolescents, 17.81 young adults, and 16.77 parents) and proportions answering ≥ 80% of the questions correctly (44.9% adolescents, 76.8% young adults, and 64.3% parents) increased significantly. Regression analysis indicated statistically significant differences (p < .001) in comprehension scores between the enhanced and standard groups (ß = 3.87 adolescents, ß = 4.03 young adults, and ß = 3.60 parents) after controlling for sociodemographic factors. DISCUSSION: Enhancing consent procedures with extended discussions, quizzes, and additional explanation where understanding is inadequate is a promising approach for improving comprehension. However, poorer comprehension among adolescents compared to young adults and parents underscores the need for research to identify additional approaches to improve understanding.

OBJECTIVE: To compare HIV prevalence estimates from routine programme data in antenatal care (ANC) clinics in western Kenya with HIV prevalence estimates in a general population sample in the era of universal test and treat (UTT). METHODS: The study was conducted in the area covered by the Siaya Health Demographic Surveillance System (Siaya HDSS) in western Kenya and used data from ANC clinics and the general population. ANC data (n = 1,724) were collected in 2018 from 13 clinics located within the HDSS. The general population was a random sample of women of reproductive age (15-49) who reside in the Siaya HDSS and participated in an HIV sero-prevalence survey in 2018 (n = 2,019). Total and age-specific HIV prevalence estimates were produced from both datasets and demographic decomposition methods were used to quantify the contribution of the differences in age distributions and age-specific HIV prevalence to the total HIV prevalence estimates. RESULTS: Total HIV prevalence was 18.0% (95% CI 16.3-19.9%) in the ANC population compared with 18.4% (95% CI 16.8-20.2%) in the general population sample. At most ages, HIV prevalence was higher in the ANC population than in the general population. The age distribution of the ANC population was younger than that of the general population, and because HIV prevalence increases with age, this reduced the total HIV prevalence among ANC attendees relative to prevalence standardised to the general population age distribution. CONCLUSION: In the era of UTT, total HIV prevalence among ANC attendees and the general population were comparable, but age-specific HIV prevalence was higher in the ANC population in most age groups. The expansion of treatment may have led to changes in both the fertility of women living with HIV and their use of ANC services, and our results lend support to the assertion that the relationship between ANC and general population HIV prevalence estimates are highly dynamic.

Ethical concerns about risks to minor adolescents participating in HIV prevention research is a barrier to their inclusion. One concern is whether HIV testing and results disclosure venue affects the health and behavior of adolescent participants. We assessed for differential effects on quality of life (QOL), depressive symptoms, and sexual behavior due to (1) testing venue (home or health facility) and (2) test result (HIV-positive, HIV-negative, indeterminate). We collected data at three timepoints (baseline, 2-month follow-up, 12-month follow-up) from 113 Kenyan adolescents aged 15-19 (51% female). We analyzed the data using linear mixed effects models for the QOL and depressive symptoms outcomes and a logistic model for the sexual behavior outcome. Results showed a small mental health benefit for adolescents tested for HIV at a health facility compared with home. There was little evidence that testing venue influenced sexual behavior or that test results moderated the effects of HIV testing across all outcomes. The decision to conduct HIV testing at home or a health facility may not be very consequential for adolescents' health and behavior. Findings underscore the need to critically examine assumptions about adolescent vulnerability to better promote responsible conduct of HIV prevention research with youth in sub-Saharan Africa.

Depression is a major cause of disease burden and is linked to poor quality of life (QOL) among adolescents. We examined the roles of sexual behaviors, HIV risk perception, and anticipated HIV stigma on depressive symptomatology and QOL among 4096 adolescents in a rural region of western Kenya with a high burden of HIV. Participants were aged 15-19 years, had not been tested for HIV in the previous 6 months, and had never been diagnosed with HIV. Anticipated stigma and risk perception were directly associated with depressive symptomatology and QOL. There was evidence of small indirect effects-through stigma-of risk perception on depressive symptomatology and QOL. Gender moderated relationships between sexual behavior and risk perception, depressive symptomatology, and QOL. Results suggest that developing effective gender-based interventions to address stigma, sexual behavior, and risk perception may be important for improving adolescent well-being in high HIV prevalence contexts.
RESUMEN: La depresión es una de las principales causas de carga de morbilidad y se asocia con una pobre calidad de vida (CdV) de los adolescentes. Nosotros estudiamos el papel de los comportamientos sexuales, la percepción de riesgo del VIH, y el estigma anticipado del VIH en relación con la sintomatología depresiva y la CdV de 4 096 adolescentes provenientes de una región rural del oeste de Kenia con alta carga de VIH. Los participantes, adolescentes de entre 15 y 19 años, no se habían hecho la prueba de detección del VIH en los últimos 6 meses y, además, nunca habían sido diagnosticados con VIH. El estigma anticipado y la percepción de riesgo estaban asociados directamente con la sintomatología depresiva y la CdV. Hubo evidencia de pocos efectos indirectos de percepción de riesgogenerados por el estigmaen la sintomatología depresiva y la CdV. El género moderó las relaciones entre el comportamiento sexual y la percepción de riesgo, la sintomatología depresiva y la CdV. Los resultados sugieren que desarrollar intervenciones con enfoque de género para abordar el tema del estigma, los comportamientos sexuales y la percepción de riesgo, puede ser importante para mejorar el bienestar de los adolescentes que viven en un contexto con alta prevalencia de VIH.

The study purpose was to determine the prevalence and determinants of suicidal thoughts and behaviours in a rural community sample of 15-19-year-old Kenyan adolescents in a region with high HIV burden. Data were from an observational study examining ethical issues in adolescent HIV research (N=4084). Participants reporting suicidal ideation were assessed for suicide risk. Directed content analyses were conducted using assessment reports. Logistic regression was used to identify factors associated with suicide outcomes. Prevalence of suicidal ideation was 16%. Of these, 38% were low risk and 12% were moderate/high-risk. Females and sexually active adolescents had higher odds of suicidal ideation and being categorised as moderate/high-risk. Adolescents with higher depression scores had higher odds of reporting ideation. Pregnancy was protective for females while impregnating a partner was a risk factor for males. Abuse from a family member, financial stress and health concerns were the most frequently mentioned precipitants of ideation. However, only abuse increased odds of suicide behaviour. Effective programmes to identify and support sexually active, pregnant, and distressed adolescents at risk for suicide are needed. Approaches involving families, schools, health facilities, and community gatekeepers may have the most promise in sub-Saharan African rural areas with limited mental health services.

In priority sub-Saharan African countries, on the ground observations suggest that the success of voluntary medical male circumcision (VMMC) programs should not be based solely on numbers of males circumcised. We identify gaps in the consent process and poor psychosocial outcomes among a key target group: male adolescents. We assessed compliance with consent and assent requirements for VMMC in western Kenya among males aged 15-19 (N = 1939). We also examined differences in quality of life, depression, and anticipated HIV stigma between uncircumcised and circumcised adolescents. A substantial proportion reported receiving VMMC services as minors without parent/guardian consent. In addition, uncircumcised males were significantly more likely than their circumcised peers to have poor quality of life and symptoms of depression. Careful monitoring of male adolescents' well-being is needed in large-scale VMMC programs. There is also urgent need for research to identify effective strategies to address gaps in the delivery of VMMC services.

Despite a pressing need for adolescent HIV research in sub-Saharan Africa, ethical guidance for conducting research among minor adolescents is lacking. One ethical issue is the degree to which parents should be involved in the research process. The existing discourse is predominantly speculative and focuses on negative consequences of parental involvement. We use empirical data to describe the perspectives of Kenyan adolescents on parental involvement in consent and disclosure of HIV test results within a research study context. We conducted two rounds of focus group discussions with 40 adolescents in western Kenya to ask about minor adolescent participation in HIV research. We analysed data using codes and matrices. Kenyan adolescents were largely in favour of parental involvement during the research process. Half felt adolescent minors should solicit parental consent to participate, and nearly all said parents should learn the HIV test results of adolescent minors in order to provide necessary support. From their perspective, involvement of parents in research extends beyond obtaining their consent to providing essential support for youth, regardless of HIV status, both during and beyond the research study. Ethical guidelines that prioritise adolescent autonomy in research must consider reasons to involve parents considered important by adolescents themselves, particularly in low-resource settings.

Assessment of benefits is traditionally regarded as crucial to the ethical evaluation of research involving human participants. We conducted focus group discussions (FGDs) with health and other professionals engaged with adolescents, caregivers/parents, and adolescents in Siaya County, Kenya, to solicit opinions about appropriate ways of conducting HIV research with adolescents. Our data revealed that many focus group participants have a profoundly positive conception of participation in health research, including studies conferring seemingly few benefits. In this article, we identify and analyze five different but interrelated types of benefits as perceived by Kenyan adolescent and adult stakeholders in HIV research, and discuss their ethical significance. Our findings suggest that future empirical and conceptual research should concentrate on factors that may trigger researcher obligations to improve benefit perceptions among research participants.

BACKGROUND: In 1997, a survey in Kisumu found a prevalence of HIV infection among female sex workers (FSW) of 75%. Only 50% reported using a condom with the last client. In 2008, we conducted another survey to collect data to inform an intervention targeting FSW in Kisumu. METHODS: In 2008 FSW were recruited by respondent-driven sampling. Women completed a questionnaire and were tested for HIV and other sexually transmitted infections (STIs). Multiple logistic regression analysis was done to explore factors associated with HIV-infection, and with condom use. Prevalence of HIV infection was compared in the two surveys from 1997 and 2008. Multivariate analysis was used to assess whether a change in HIV prevalence between the two surveys could be explained by changes in socio-demographic characteristics and/or behavioral factors. RESULTS: 481 FSW participated in the 2008 study. HIV prevalence was 56.5% (95% CI 52.0-61.6). Factors independently associated with HIV were age older than 29 years; being a widow; STI treatment in the past year; herpes simplex virus Type-2 infection; bacterial vaginosis; and trichomoniasis. Condom use with last client was reported by 75.0% (95% CI 70.9-78.9). Predictors of condom use with the last client were age older than 29 years; higher price paid by last client; ever having been tested for HIV. Predictors of unprotected sex were being drunk during last sex act; usually having sex during menses; and STI treatment in the past year. The odds ratio of HIV infection associated with year of survey was 0.49 (95% CI 0.33-0.75) after adjusting for socio-demographic and behavioral factors. CONCLUSIONS: The prevalence of HIV among FSW in Kisumu was found to be lower in 2008 than in 1997, while reported condom use was higher. However, access to HIV/STI prevention and care services needs to improve to further decrease HIV transmission between FSW and their clients.

OBJECTIVE: To estimate the female sex worker population size in three cities in Côte d'Ivoire and in Kisumu, Kenya. METHODS: Capture-recapture was used, calculating size estimates by first 'tagging' a number of individuals and, through an independent recapture, calculating the proportion of overlap. The same procedures were used in all four cities. In the first phase, members of the target population were 'captured' and 'marked' by giving them a capture card. Six days later, in the same places and at the same time, a second sample was 'captured', which comprised a certain number of people who were captured in the first round. During the exercise, questions were asked to estimate the coverage of the sex worker clinics. RESULTS: Using capture-recapture, the estimated number of female sex workers was 1160 in Yamoussoukro (95% CI 1053-1287), 1202 in Bouaké (95% CI 1128-1279), 1916 in San Pedro (95% CI 1809-2030) and 1350 in Kisumu (95% CI 1261-1443). The proportion of female sex workers in Côte d'Ivoire who had visited the clinic ranged from 15% in Yamoussoukro to 30% in San Pedro and was 34% in Kisumu. CONCLUSIONS: Capture-recapture was successfully applied to estimate the population size of female sex workers. These estimations were urgently needed to help mobilize an increased response to HIV, to assess programme coverage and to estimate potential impact of the targeted intervention.
