RESUMEN

BACKGROUND: The DREAMS Partnership promotes combination HIV prevention among adolescent girls and young women. We examined the extent to which DREAMS interventions reached early adolescent girls (EAG; aged 10-14 years) in two informal settlements in Nairobi, and the characteristics of those reached, after 3 years of implementation. METHODS: We utilized three data rounds from a randomly-sampled cohort of EAG established in 2017 in Korogocho and Viwandani informal settlements where DREAMS interventions were implemented. Interventions were classified as individual or contextual-level, with individual interventions further categorised as primary (prioritised for this age group), or secondary. We summarised self-reported invitation to participate in DREAMS, and uptake of eight interventions that were supported by DREAMS, during 2017-2019. Multivariable logistic regression analysis was used to identify individual and household characteristics associated with invitation to DREAMS and uptake of primary interventions. RESULTS: Data were available for 606, 516 (retention rate of 85%) and 494 (82%) EAG in 2017, 2018 and 2019, respectively. Proportions invited to DREAMS increased from 49% in 2017, to 77% by 2018, and to 88% by 2019. School-based HIV and violence prevention, and HIV testing and counselling were the most accessed interventions (both at 82%). Cumulative uptake of interventions was higher among those invited to participate in DREAMS compared to those never invited, particularly for new interventions such as social asset building and financial capability training. Contextual-level interventions were accessed infrequently. Most of those invited both in 2017 and 2018 accessed ≥3 interventions (96%), and 55% received all three primary interventions by 2019. CONCLUSIONS: Uptake of DREAMS interventions among a representative sample of EAG was high and quickly increased over the implementation period. The majority accessed multiple interventions, indicating that it is feasible to integrate and deliver a package of interventions to EAG in a challenging informal context.

RESUMEN

BACKGROUND: North Eastern Kenya has persistently had poor maternal, new-born and child health (MNCH) indicators. Barriers to access and utilisation of MNCH services are structural, individual and community-level factors rooted in sociocultural norms. A package of interventions was designed and implemented in Garissa sub-County aimed at creating demand for services. Community Health Volunteers (CHVs) were trained to generate demand for and facilitate access to MNCH care in communities, while health care providers were trained on providing culturally acceptable and sensitive services. Minor structural improvements were made in the control areas of two facilities to absorb the demand created. Community leaders and other social actors were engaged as influencers for demand creation as well as to hold service providers accountable. This qualitative research was part of a larger mixed methods study and only the qualitative results are presented. In this paper, we explore the barriers to health care seeking that were deemed persistent by the end of the intervention period following a similar assessment at baseline. METHODS: An exploratory qualitative research design with participatory approach was undertaken as part of an impact evaluation of an innovation project in three sites (two interventions and one control). Semi-structured interviews were conducted with women who had given birth during the intervention period. Focus group discussions were conducted among the wider community members and key informant interviews among healthcare managers and other stakeholders. Participants were purposively selected. Data were analysed using content analysis by reading through transcripts. Interview data from different sources on a single event were triangulated to increase the internal validity and analysis of multiple cases strengthened external validity. RESULTS: Three themes were pre-established: 1) barriers and solutions to MNCH use at the community and health system level; 2) perceptions about women delivering in health facilities and 3) community/social norms on using health facilities. Generally, participants reported satisfaction with services offered in the intervention health facilities and many indicated that they would use the services again. There were notable differences between the intervention and control site in attitudes towards use of services (skilled birth attendance, postnatal care). Despite the apparent improvements, there still exist barriers to MNCH services use. Persistent barriers identified were gender of service provider, insecurity, poverty, lack of transport, distance from health facilities, lack of information, absence of staff especially at night-time and quality of maternity care. CONCLUSION: Attitudes towards MNCH services are generally positive, however some barriers still hinder utilization. The County health department and community leaders need to sustain the momentum gained by ensuring that service access and quality challenges are continually addressed.

RESUMEN

Mental health issues are a predisposing factor for HIV acquisition. We examined the association between depressive symptoms and patterns of sexual experience among girls aged 10-14 years living in Korogocho and Viwandani slums in Nairobi, Kenya. We analysed data collected in 2017 from a random sample of 606 girls. Using Latent Class Analysis, we modelled patterns of sexual experiences and used multivariable regression analysis to determine the association between self-reported depressive symptoms and sexual experiences. Seven in ten girls reported at least one symptom of self-reported depression in the past 12 months. About 13% of girls had had a sexual experience, resulting in two patterns of sexual experience - naïve and experienced. Girls reporting depressive symptoms were more likely to be sexually experienced. Sexual and reproductive health programs targeting adolescent girls should consider including intervention packages that address mental health conditions such as depression.

RESUMEN

BACKGROUND: The North Eastern region in Kenya experiences challenges in the utilization of maternal and newborn health services. In this region, culture and religion play a major role in influencing healthcare seeking behaviour of the community. This study was conducted to (i) understand key inherent barriers to health facility delivery in the Somali community of North Eastern Kenya and (ii) inform interventions on specific needs of this community. METHODS: The study was conducted among community members of Garissa sub-County as part of a baseline assessment before the implementation of an intervention package aimed at creating demand and increasing utilization of maternal and newborn services. Focus group discussions and key informant interviews were conducted with clan leaders, Imams, health managers, member of the county assembly, and service users (women and men) in three locations of Garissa sub-County. Data were analysed through content analysis, by coding recurrent themes and pre-established themes. RESULTS: Using health facility for delivery was widely acceptable and most respondents acknowledged the advantages and benefits of skilled birth delivery. However, a commonly cited barrier in using health facility delivery was the issue of male nurses and doctors attending to women in labour. According to participants, it is against their culture and thus a key disincentive to using maternity services. Living far from the health facility and lack of a proper and reliable means of transportation was also highlighted as a reason for home delivery. At the health facility level, respondents complained about the poor attitude of health care providers, especially female nurses being disrespectful; and the limited availability of healthcare workers, equipment and supplies. Lack of awareness and information on the importance of skilled birth attendance was also noted. CONCLUSION: To increase health facility delivery, interventions need to offer services that take into consideration the sociocultural aspect of the recipients. Culturally acceptable and sensitive services, and awareness on the benefits of skilled birth attendance among the community members are likely to attract more women to use maternity services and thus reduce adverse maternal and newborn health outcomes.

RESUMEN

BACKGROUND: The DREAMS Partnership is an ambitious effort to deliver combinations of biomedical, behavioural and structural interventions to reduce HIV incidence among adolescent girls and young women (AGYW). To inform multi-sectoral programming at scale, across diverse settings in Kenya and South Africa, we identified who the programme is reaching, with which interventions and in what combinations. METHODS: Randomly-selected cohorts of 606 AGYW aged 10-14 years and 1081 aged 15-22 years in Nairobi and 2184 AGYW aged 13-22 years in uMkhanyakude, KwaZulu-Natal, were enrolled in 2017, after ~ 1 year of DREAMS implementation. In Gem, western Kenya, population-wide cross-sectional survey data were collected during roll-out in 2016 (n = 1365 AGYW 15-22 years). We summarised awareness and invitation to participate in DREAMS, uptake of interventions categorised by the DREAMS core package, and uptake of a subset of 'primary' interventions. We stratified by age-group and setting, and compared across AGYW characteristics. RESULTS: Awareness of DREAMS was higher among younger women (Nairobi: 89%v78%, aged 15-17v18-22 years; uMkhanyakude: 56%v31%, aged 13-17v18-22; and Gem: 28%v25%, aged 15-17v18-22, respectively). HIV testing was the most accessed intervention in Nairobi and Gem (77% and 85%, respectively), and school-based HIV prevention in uMkhanyakude (60%). Among those invited, participation in social asset building was > 50%; > 60% accessed ≥2 core package categories, but few accessed all primary interventions intended for their age-group. Parenting programmes and community mobilisation, including those intended for male partners, were accessed infrequently. In Nairobi and uMkhanyakude, AGYW were more likely to be invited to participate and accessed more categories if they were: aged < 18 years, in school and experienced socio-economic vulnerabilities. Those who had had sex, or a pregnancy, were less likely to be invited to participate but accessed more categories. CONCLUSIONS: In representative population-based samples, awareness and uptake of DREAMS were high after 1 year of implementation. Evidence of 'layering' (receiving multiple interventions from the DREAMS core package), particularly among more socio-economically vulnerable AGYW, indicate that intervention packages can be implemented at scale, for intended recipients, in real-world contexts. Challenges remain for higher coverage and greater 'layering', including among older, out-of-school AGYW, and community-based programmes for families and men.

RESUMEN

Donor human milk (DHM) is recomended as the best alternative when use of mothers' own milk is not a feasible option. Kenya has not yet established human milk banks (HMBs) for provision of safe DHM, which is free from any physical, chemical, microbiological contaminants or pathogens. This study aimed to establish the perceptions on donating and using DHM, and establishing HMBs in Kenya. Qualitative data were collected through 17 focus group discussions, 29 key informant interviews, and 25 in-depth interviews, with women of childbearing age, community members, health workers, and policy makers. Quantitative interviews were conducted with 868 mothers of children younger than 3 years. Descriptive analysis of quantitative data was performed in STATA software, whereas qualitative interviews were coded using NVIVO and analysed thematically. Majority of them had a positive attitude towards donating breast milk to a HMB (80%) and feeding children on DHM (87%). At a personal level, participants were more willing to donate their milk to HMBs (78%) than using DHM for their own children (59%). The main concerns on donation and use of DHM were personal dislikes, fear of transmission of diseases including HIV, and hygiene concerns. Ensuring safety of DHM was considered important in enhancing acceptability of DHM and successful establishment of the HMBs. When establishing HMBs, Kenya must take into consideration communication strategies to address the main concerns raised regarding the quality and safety of the DHM. The findings will contribute to the development of HMB guidelines in Kenya and other African contexts.

RESUMEN

BACKGROUND: HIV risk remains unacceptably high among adolescent girls and young women (AGYW) in southern and eastern Africa, reflecting structural and social inequities that drive new infections. In 2015, PEPFAR (the United States President's Emergency Plan for AIDS Relief) with private-sector partners launched the DREAMS Partnership, an ambitious package of interventions in 10 sub-Saharan African countries. DREAMS aims to reduce HIV incidence by 40% among AGYW over two years by addressing multiple causes of AGYW vulnerability. This protocol outlines an impact evaluation of DREAMS in four settings. METHODS: To achieve an impact evaluation that is credible and timely, we describe a mix of methods that build on longitudinal data available in existing surveillance sites prior to DREAMS roll-out. In three long-running surveillance sites (in rural and urban Kenya and rural South Africa), the evaluation will measure: (1) population-level changes over time in HIV incidence and socio-economic, behavioural and health outcomes among AGYW and young men (before, during, after DREAMS); and (2) causal pathways linking uptake of DREAMS interventions to 'mediators' of change such as empowerment, through to behavioural and health outcomes, using nested cohort studies with samples of ~ 1000-1500 AGYW selected randomly from the general population and followed for two years. In Zimbabwe, where DREAMS includes an offer of pre-exposure HIV prophylaxis (PrEP), cohorts of young women who sell sex will be followed for two years to measure the impact of 'DREAMS+PrEP' on HIV incidence among young women at highest risk of HIV. In all four settings, process evaluation and qualitative studies will monitor the delivery and context of DREAMS implementation. The primary evaluation outcome is HIV incidence, and secondary outcomes include indicators of sexual behavior change, and social and biological protection. DISCUSSION: DREAMS is, to date, the most ambitious effort to scale-up combinations or 'packages' of multi-sectoral interventions for HIV prevention. Evidence of its effectiveness in reducing HIV incidence among AGYW, and demonstrating which aspects of the lives of AGYW were changed, will offer valuable lessons for replication.

RESUMEN

BACKGROUND: The recently promulgated 2010 constitution of Kenya permits abortion when the life or health of the woman is in danger. Yet broad uncertainty remains about the interpretation of the law. Unsafe abortion remains a leading cause of maternal morbidity and mortality in Kenya. The current study aimed to determine the incidence of induced abortion in Kenya in 2012. METHODS: The incidence of induced abortion in Kenya in 2012 was estimated using the Abortion Incidence Complications Methodology (AICM) along with the Prospective Morbidity Survey (PMS). Data were collected through three surveys, (i) Health Facilities Survey (HFS), (ii) Prospective Morbidity Survey (PMS), and (iii) Health Professionals Survey (HPS). A total of 328 facilities participated in the HFS, 326 participated in the PMS, and 124 key informants participated in the HPS. Abortion numbers, rates, ratios and unintended pregnancy rates were calculated for Kenya as a whole and for five geographical regions. RESULTS: In 2012, an estimated 464,000 induced abortions occurred in Kenya. This translates into an abortion rate of 48 per 1,000 women aged 15-49, and an abortion ratio of 30 per 100 live births. About 120,000 women received care for complications of induced abortion in health facilities. About half (49%) of all pregnancies in Kenya were unintended and 41% of unintended pregnancies ended in an abortion. CONCLUSION: This study provides the first nationally-representative estimates of the incidence of induced abortion in Kenya. An urgent need exists for improving facilities' capacity to provide safe abortion care to the fullest extent of the law. All efforts should be made to address underlying factors to reduce risk of unsafe abortion.

RESUMEN

BACKGROUND: Complications due to unsafe abortion cause high maternal morbidity and mortality, especially in developing countries. This study describes post-abortion complication severity and associated factors in Kenya. METHODS: A nationally representative sample of 326 health facilities was included in the survey. All regional and national referral hospitals and a random sample of lower level facilities were selected. Data were collected from 2,625 women presenting with abortion complications. A complication severity indicator was developed as the main outcome variable for this paper and described by women's socio-demographic characteristics and other variables. Ordered logistic regression models were used for multivariable analyses. RESULTS: Over three quarters of abortions clients presented with moderate or severe complications. About 65% of abortion complications were managed by manual or electronic vacuum aspiration, 8% by dilation and curettage, 8% misoprostol and 19% by forceps and fingers. The odds of having moderate or severe complications for mistimed pregnancies were 43% higher than for wanted pregnancies (OR, 1.43; CI 1.01-2.03). For those who never wanted any more children the odds for having a severe complication was 2 times (CI 1.36-3.01) higher compared to those who wanted the pregnancy then. Women who reported inducing the abortion had 2.4 times higher odds of having a severe complication compared to those who reported that it was spontaneous (OR, 2.39; CI 1.72-3.34). Women who had a delay of more than 6 hours to get to a health facility had at least 2 times higher odds of having a moderate/severe complication compared to those who sought care within 6 hours from onset of complications. A delay of 7-48 hours was associated with OR, 2.12 (CI 1.42-3.17); a delay of 3-7 days OR, 2.01 (CI 1.34-2.99) and a delay of more than 7 days, OR 2.35 (CI 1.45-3.79). CONCLUSIONS: Moderate and severe post-abortion complications are common in Kenya and a sizeable proportion of these are not properly managed. Factors such as delay in seeking care, interference with pregnancy, and unwanted pregnancies are important determinants of complication severity and fortunately these are amenable to targeted interventions.

RESUMEN

The DREAMS partnership aims to deliver a comprehensive package to reduce HIV incidence among adolescent girls and young women (AGYW), including through shifting gender norms. We evaluate DREAMS' effect on attitudes towards gender norms in two Kenyan settings. AGYW aged 15-22 in Nairobi (n = 852) and Gem (n = 761) were randomly selected for cohort enrolment in 2017-18 and followed-up to 2019. We described the proportion of AGYW and their male peers with equitable attitudes towards gender norms, using an adapted version of the GEM scale. We estimated the association between self-reported invitation to DREAMS (in 2017-18) and AGYW's attitudes towards two dimensions of gender norms, and then applied a causal inference framework to estimate the difference in the proportion of AGYW with equitable attitudes under the counterfactual scenarios that all versus none were DREAMS beneficiaries. We estimated that overall, 90.2% versus 87.1% of AGYW would have equitable norms around sexual and reproductive health decision-making in Nairobi if all versus none were DREAMS beneficiaries (+3.1; 95%CI:-2.5, +9.0). In Gem, we estimated a risk difference of +1.0 (89.6% vs 88.6%, 95%CI: -3.6,+5.6). There was no evidence for an effect of DREAMS on attitudes towards violence-related norms (Nairobi: 82.7% vs 82.2%, +0.5; 95%CI: -5.3,+6.5; Gem: 44.3% vs 48.2%, -3.9; 95%CI: -11.7,+3.0). We found no evidence of an impact of DREAMS invitation on individual attitudes towards gender norms. In some cases, equitable attitudes at enrolment left limited scope for improvement, and additional effort may be required to shift inequitable violence attitudes among both AGYW and their male peers.

RESUMEN

Kenya still faces major challenges due to the HIV/AIDS epidemic. This study examined the association between marital status and risk of HIV infection in urban slums of Nairobi. Data were derived from a cross-sectional population-based survey nested in an ongoing Demographic Surveillance System in two urban slums in Nairobi. Descriptive statistics and multivariate logistic regression analysis were used to describe the characteristics of the sample and to assess the association between marital status and risk of HIV infection. HIV prevalence among married men and women was 10.4% and 11.1% and among divorced/separated/widowed men and women was 14.9% and 27.9%. Multivariate results showed the risk of acquiring HIV was significantly associated with being married, divorced/separated/widowed, being in the older age groups and the Luo ethnic group. There is urgent need for appropriate HIV prevention interventions targeted at the urban poor to address the high risk of HIV infections in this population.

RESUMEN

DREAMS aims to reduce HIV incidence among adolescent girls and young women (AGYW) by tackling drivers of HIV risk including gender-based violence. We evaluate the impact of DREAMS on recent experiences of violence perpetuated by men against AGYW. AGYW cohorts were randomly selected from demographic platforms in South Africa (rural KwaZulu-Natal) and Kenya (Nairobi informal settlements and rural Gem sub-county). AGYW aged 13-22 years were enrolled in 2017 (Nairobi, KwaZulu-Natal) or 2018 (Gem), with annual follow-up to 2019. We described proportions of AGYW who self-reported experiences of violence perpetrated by males in the 12 months preceding the interview, overall and by form (physical, sexual, emotional). We investigated associations with DREAMS (invitation to participate during 2017-2018) through multivariable propensity score-adjusted logistic regression and estimated the causal effect of DREAMS on experiences of violence, under counter-factual scenarios in which all versus no AGYW were DREAMS beneficiaries. Among 852, 1018 and 1712 AGYW followed-up in 2019 in Nairobi, Gem and KZN, respectively, proportions reporting any violence in 2019 were higher in Nairobi (29%) than Gem (18%) and KwaZulu-Natal (19%). By sub-type, emotional and physical violence were more frequently reported than sexual violence. We found no evidence of an impact attributable to DREAMS on overall levels of violence, in any setting. Nor was there evidence of impact on sub-types of violence, with one exception: an increase in physical violence in Nairobi if all, versus no, AGYW were DREAMS beneficiaries (16% vs 11%; +5% difference [95% CI: +0.2%, +10.0%]). Experiences of gender-based violence were common among AGYW, especially in urban settings, and DREAMS had no measurable impact on reducing violence within three years of implementation. Violence prevention programming that reaches more men and the broader community, sustained for longer periods, may yield greater gains in violence reduction than AGYW-focused programming. Additionally, more investment in implementation research is needed to bridge trial-based study findings from efficacy to population-level effectiveness.

RESUMEN

INTRODUCTION: Global morbidity from enteric infections and diarrhoea remains high in children in low-income and middle-income countries, despite significant investment over recent decades in health systems and water and sanitation infrastructure. Other types of societal development may be required to reduce disease burden. Ecological research on the influence of household and neighbourhood societal development on pathogen transmission dynamics between humans, animals and the environment could identify more effective strategies for preventing enteric infections. METHODS AND ANALYSIS: The 'enteric pathome'-that is, the communities of viral, bacterial and parasitic pathogens transmitted from human and animal faeces through the environment is taxonomically complex in high burden settings. This integrated cohort-exposure assessment study leverages natural socioeconomic spectrums of development to study how pathome complexity is influenced by household and neighbourhood infrastructure and hygiene conditions. We are enrolling under 12-month-old children in low-income and middle-income neighbourhoods of two Kenyan cities (Nairobi and Kisumu) into a 'short-cohort' study involving repeat testing of child faeces for enteric pathogens. A mid-study exposure assessment documenting infrastructural, behavioural, spatial, climate, environmental and zoonotic factors characterises pathogen exposure pathways in household and neighbourhood settings. These data will be used to inform and validate statistical and agent-based models (ABM) that identify individual or combined intervention strategies for reducing multipathogen transmission between humans, animals and environment in urban Kenya. ETHICS AND DISSEMINATION: The protocols for human subjects' research were approved by Institutional Review Boards at the University of Iowa (ID-202004606) and AMREF Health Africa (ID-ESRC P887/2020), and a national permit was obtained from the Kenya National Commission for Science Technology and Innovation (ID# P/21/8441). The study was registered on Clinicaltrials.gov (Identifier: NCT05322655) and is in pre-results stage. Protocols for research on animals were approved by the University of Iowa Animal Care and Use Committee (ID 0042302).

RESUMEN

BACKGROUND: Knowledge of one's HIV status is the gateway to treatment and prevention, but remains low among young people. We investigated the early impact (2016-2017) of Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS), a multisectoral HIV prevention package, on knowledge of HIV status among adolescent girls and young women (AGYW). METHODS: In 2017, randomly selected AGYW were enrolled into surveys, N=1081 aged 15-22 years in Nairobi slum settlements, and N=2174 aged 13-22 years in rural KwaZulu-Natal. We estimated the causal effect of being a DREAMS beneficiary on knowledge of HIV status (those who self-reported as HIV-positive or tested HIV-negative in the past year), accounting for an AGYW's propensity to be a DREAMS beneficiary. RESULTS: In Nairobi, knowledge of HIV status was higher among DREAMS beneficiaries compared with non-beneficiaries (92% vs 69%, adjusted OR=8.7; 95% CI 5.8 to 12.9), with DREAMS predicted to increase the outcome by 28%, from 65% if none were a DREAMS beneficiary to 93% if all were beneficiaries. The increase attributable to DREAMS was larger among younger participants: 32% and 23% among those aged 15-17 and 18-22 years, respectively. In KwaZulu-Natal, knowledge of status was higher among DREAMS beneficiaries aged 13-17 years (37% vs 26% among non-beneficiaries), with a 9% difference due to DREAMS (95% CI 4.8% to 14.4%), and no evidence of effect among 18-22 years (-2.8%; 95% CI -11.1% to 5.7%). CONCLUSION: DREAMS substantially increased knowledge of HIV status among AGYW in Nairobi, and among younger but not older AGYW in KwaZulu-Natal. Adolescent girls can be reached early (before age 18) with community-based HIV testing programmes in diverse high-prevalence settings, with a large impact on the proportion who know their HIV status.

RESUMEN

OBJECTIVES: To evaluate uptake of a complex intervention for HIV prevention among general populations of adolescent girls and young women (AGYW) in three diverse settings. DESIGN: Cohorts of ∼1500 AGYW were randomly selected from demographic platforms in Kenya (Nairobi and Siaya) and South Africa (uMkhanyakude, KwaZulu-Natal). METHODS: AGYW aged 13/15-22 years were enrolled in 2017 (Nairobi and uMkha-nyakude) or 2018 (Siaya), with annual follow-up to 2019. We describe awareness of DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored and Safe), self-reported invitation to participate, and uptake of DREAMS interventions by: categories and levels of the PEPFAR core package;number of 'primary' interventions (seven in Kenya;five in South Africa). Analyses were stratified by year invited and age at cohort enrolment. RESULTS: Proportions aware and invited to DREAMS increased across all settings, to ≥ 83% aware and ≥ 53% invited by 2018 (highest among AGYW aged 13-17 years, e.g. 63 vs. 40% among 18-22 s, uMkhanyakude). HIV testing, school-based interventions and social protection were the most accessed categories, while differences in uptake by DREAMS invitation were greatest for novel DREAMS interventions, for example, social asset building (76% among those invited in 2017 and 2018 vs. 9% among those never-invited in Nairobi). Although few DREAMS invitees accessed all intended primary interventions by 2019 (2% of 15-17 s and 5% of 18-22 s in Gem), many accessed at least three interventions, including combinations across individual, family and community levels. CONCLUSION: Over time, DREAMS reached high proportions of AGYW in all settings, particularly younger AGYW. Participation in combinations of interventions improved but uptake of the complete primary packages remained low.

RESUMEN

OBJECTIVES: We sought evidence of DREAMS' impact on uptake of services and sexual risk among adolescent-girls-and-young-women (AGYW). DESIGN: Cohorts of AGYW aged 13-22 years were randomly selected in 2017-2018 and followed-up to 2019; 1081 in Nairobi, Kenya;1171 in Gem, western Kenya;and 2184 in uMkhanyakude, South Africa. METHODS: Outcomes were knowledge of HIV status, condomless sex (past 12 months), lifetime partners, transactional sex (past 12 months), and awareness and use of condoms and pre-exposure-prophylaxis (PrEP). Using a causal inference framework, we estimated the proportions with each outcome if all vs. none were DREAMS invitees by 2018. RESULTS: Among AGYW followed up in 2019, the percentage invited to DREAMS by 2018 was 74, 57, and 53% in Nairobi, Gem, and uMkhanyakude, respectively. By 2018, the estimated percentages of AGYW who would know their HIV status, comparing the scenarios that all vs. none were DREAMS invitees, were 86 vs. 56% in Nairobi, 80 vs. 68% in Gem, and 56 vs. 49% in uMkhanyakude. By 2019, awareness of condoms and PrEP was high among DREAMS invitees, but recent participation in condom promotion activities was less than 50% and recent PrEP use was around 0-10%. In Gem, there was evidence of a reduction attributable to DREAMS in condomless sex, and among younger AGYW in the number of lifetime partners;in Nairobi evidence of a reduction in condomless sex among sexually active older AGYW;and in uMkhanya-kude no evidence that DREAMS changed these outcomes. CONCLUSION: Alongside sustaining high levels of knowledge of HIV status, more is needed to link AGYW into prevention methods such as PrEP and condoms.Comprehensive HIV prevention promotes safer sexual partnerships, but poverty, social norms, and inequalities limit AGYW's prevention choices.

RESUMEN

INTRODUCTION: The Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS) Partnership aimed to influence psychosocial processes that promote empowerment among adolescent girls and young women (AGYW), and reduce HIV incidence. We estimated the impact of DREAMS on aspects of AGYW's collective and individual agency (specifically, social support and self-efficacy), in three settings where DREAMS was implemented from 2016 until at least end 2018. METHODS: Research cohorts of ~1500 AGYW aged 13-22 were randomly selected from demographic platforms in Kenya (Nairobi; Gem) and South Africa (uMkhanyakude) and followed up from 2017 to 2019. Social support was based on questions about female networks and access to safe places to meet with peers; general self-efficacy was measured using a scale previously validated in other settings. We conducted multivariable logistic regression, and estimated the causal effect of invitation to DREAMS on each outcome in 2018 and 2019 by comparing counter-factual scenarios in which all, vs no, AGYW were DREAMS invitees. RESULTS: In Nairobi, Gem and uMkhanyakude, respectively, 74%, 57% and 53% were invited to DREAMS by 2018. Social support was higher among DREAMS invitees versus non-invitees (eg, adjusted OR 2.0 (95% CI 1.6 to 2.6), Gem, 2018). In 2018, DREAMS increased social support in all settings and age groups, for example, from 28% if none were DREAMS invitees to 43% if all were invitees (+15% (95% CI 10% to 20%)) in Gem. Effects were strongest in Kenya, but weakened in 2019, particularly among older AGYW. In uMkhanyakude, DREAMS invitees had greater self-efficacy compared with non-invitees in 2018 (+9% (95% CI 3% to 13%), 2018) but less so in 2019. In Kenyan settings, there was weak evidence for impact on self-efficacy among younger AGYW in Gem (+6% (95% CI 0% to 13%)) and older AGYW in Nairobi (+9% (95% CI -3% to +20%)) in 2019. CONCLUSIONS: DREAMS impacted on social support and, less consistently, on self-efficacy. Weakening effects over time may reflect changes in access to safe spaces and social networks as AGYW age and change circumstances, and withdrawal of DREAMS from uMkhanyakude in 2018, highlighting the importance of programme sustainability and improving programming for older participants.

RESUMEN

BACKGROUND: Most of the studies that have informed the public health response to the COVID-19 pandemic in Kenya have relied on samples that are not representative of the general population. We conducted population-based serosurveys at three Health and Demographic Surveillance Systems (HDSSs) to determine the cumulative incidence of infection with SARS-CoV-2. METHODS: We selected random age-stratified population-based samples at HDSSs in Kisumu, Nairobi and Kilifi, in Kenya. Blood samples were collected from participants between 01 Dec 2020 and 27 May 2021. No participant had received a COVID-19 vaccine. We tested for IgG antibodies to SARS-CoV-2 spike protein using ELISA. Locally-validated assay sensitivity and specificity were 93% (95% CI 88-96%) and 99% (95% CI 98-99.5%), respectively. We adjusted prevalence estimates using classical methods and Bayesian modelling to account for the sampling scheme and assay performance. RESULTS: We recruited 2,559 individuals from the three HDSS sites, median age (IQR) 27 (10-78) years and 52% were female. Seroprevalence at all three sites rose steadily during the study period. In Kisumu, Nairobi and Kilifi, seroprevalences (95% CI) at the beginning of the study were 36.0% (28.2-44.4%), 32.4% (23.1-42.4%), and 14.5% (9.1-21%), and respectively; at the end they were 42.0% (34.7-50.0%), 50.2% (39.7-61.1%), and 24.7% (17.5-32.6%), respectively. Seroprevalence was substantially lower among children (<16 years) than among adults at all three sites (p≤0.001). CONCLUSION: By May 2021 in three broadly representative populations of unvaccinated individuals in Kenya, seroprevalence of anti-SARS-CoV-2 IgG was 25-50%. There was wide variation in cumulative incidence by location and age.

RESUMEN

Injuries contribute significantly to the rising morbidity and mortality attributable to non-communicable diseases in the developing world. Unfortunately, active injury surveillance is lacking in many developing countries, including Kenya. This study aims to describe and identify causes of and risk factors for fatal injuries in two slums in Nairobi city using a demographic surveillance system framework. The causes of death are determined using verbal autopsies. We used a nested case-control study design with all deaths from injuries between 2003 and 2005 as cases. Two controls were randomly selected from the non-injury deaths over the same period and individually matched to each case on age and sex. We used conditional logistic regression modeling to identity individual- and community-level factors associated with fatal injuries. Intentional injuries accounted for about 51% and unintentional injuries accounted for 49% of all injuries. Homicides accounted for 91% of intentional injuries and 47% of all injury-related deaths. Firearms (23%) and road traffic crashes (22%) were the leading single causes of deaths due to injuries. About 15% of injuries were due to substance intoxication, particularly alcohol, which in this community comes from illicit brews and is at times contaminated with methanol. Results suggest that in the pervasively unsafe and insecure environment that characterizes the urban slums, ethnicity, residence, and area level factors contribute significantly to the risk of injury-related mortality.

RESUMEN

BACKGROUND: Counselling and testing is important in HIV prevention and care. Majority of people in sub-Saharan Africa do not know their HIV status and are therefore unable to take steps to prevent infection or take up life prolonging anti-retroviral drugs in time if infected. This study aimed at exploring determinants of HIV testing and counselling in two Nairobi informal settlements. METHODS: Data are derived from a cross-sectional survey nested in an ongoing demographic surveillance system. A total of 3,162 individuals responded to the interview and out of these, 82% provided a blood sample which was tested using rapid test kits. The outcome of interest in this paper was HIV testing status in the past categorised as "never tested"; "client-initiated testing and counselling (CITC)" and provider-initiated testing and counselling (PITC). Multinomial logistic regression was used to identify determinants of HIV testing. RESULTS: Approximately 31% of all respondents had ever been tested for HIV through CITC, 22% through PITC and 42% had never been tested but indicated willingness to test. Overall, 62% of females and 38% of males had ever been tested for HIV. Males were less likely to have had CITC (OR = 0.47; p value < 0.001) and also less likely to have had PITC (OR = 0.16; p value < 0.001) compared to females. Individuals aged 20-24 years were more likely to have had either CITC or PITC compared to the other age groups. The divorced/separated/widowed were more likely (OR = 1.65; p value < 0.01) to have had CITC than their married counterparts, while the never married were less likely to have had either CITC or PITC. HIV positive individuals (OR = 1.60; p value < 0.01) and those who refused testing in the survey (OR = 1.39; p value < 0.05) were more likely to have had CITC compared to their HIV negative counterparts. CONCLUSION: Although the proportion of individuals ever tested in the informal settlements is similar to the national average, it remains low compared to that of Nairobi province especially among men. Key determinants of HIV testing and counselling include; gender, age, education level, HIV status and marital status. These factors need to be considered in efforts aimed at increasing participation in HIV testing.
