Impact of a livelihood intervention on gender roles and relationship power among people with HIV

OBJECTIVE

To evaluate the impact of an agricultural livelihood intervention on gender role conflict and sexual relationship power among people with HIV (PWH) in western Kenya.

DESIGN

Study participants were enrolled in Shamba Maisha , a cluster randomized controlled trial of an agricultural intervention conducted among PWH across 16 health facilities during 2016-2020. Intervention participants received a water pump, seeds, and agricultural and financial training; control participants received standard of HIV care.

METHODS

We assessed men's views on masculinity and gender roles via the validated gender role conflict score (GRCS; range 18-78, higher = greater gender role conflict). We measured gender power imbalances among women via the validated Sexual Relationship Power Scale (SRPS), which combines subscales of relationship control and decision-making dominance (range 1-4, higher = female holds more power). We compared changes over the study period by arm using longitudinal multilevel difference-in-difference linear regression models accounting for clustering of facilities using the intention-to-treat cohort.

RESULTS

We enrolled 720 participants (366 intervention, 354 control); 2-year retention was 94%. Median age was 40 and approximately 55% of participants were female. Among men, after 24-months the decrease in GRCS scores was 4.3 points greater in the intervention than the control arm ( P  < 0.001). Among women, the intervention resulted in 0.25 points greater increase in the SRPS compared to the control arm ( P  < 0.001).

CONCLUSIONS

Shamba Maisha resulted in less gender role conflict in men and greater sexual relationship power for women. Agricultural livelihood interventions may be a powerful tool to improve gender power imbalances, which may subsequently mitigate poverty and food insecurity.

Many Cooks in the Kitchen: Iterating a Qualitative Analysis Process Across Multiple Countries, Sites, and Teams

Establishing and proving methodological rigor has long been a challenge for qualitative researchers where quantitative methods prevail, but much published literature on qualitative analysis assumes a relatively small number of researchers working in relative proximity. This is particularly true for research conducted with a grounded theory approach. Different versions of grounded theory are commonly used, but this methodology was originally developed for a single researcher collecting and analyzing data in isolation. Although grounded theory has evolved since its development, little has been done to reconcile this approach with the changing nature and composition of international research teams. Advances in technology and an increased emphasis on transnational collaboration have facilitated a shift wherein qualitative datasets have been getting larger and the teams collecting and analyzing them more diverse and diffuse. New processes and systems are therefore required to respond to these conditions. Data for this article are drawn from the experiences of the Innovations for Choice and Autonomy (ICAN) Research Consortium. ICAN aims to understand how self-injectable contraceptives can be implemented in ways that best meet women's needs in Kenya, Uganda, Malawi, and Nigeria. We found that taking a structured approach to analysis was important for maintaining consistency and making the process more manageable across countries. However, it was equally important to allow for flexibility within this structured approach so that teams could adapt more easily to local conditions, making data collection and accompanying analysis more feasible. Meaningfully including all interested researchers in the analysis process and providing support for learning also increased rigor. However, competing priorities in a complex study made it difficult to adhere to planned timelines. We conclude with recommendations for both funders and study teams to design and conduct global health studies that ensure more equitable contributions to analysis while remaining logistically feasible and methodologically sound.

Links between Household-Level Income-Generating Agricultural Intervention and the Psychological Well-Being of Adolescent Girls in Human Immunodeficiency Virus-Affected Households in Southwestern Kenya: A Qualitative Inquiry

BACKGROUND

Adolescent girls may experience poor psychological well-being, such as social isolation, shame, anxiety, hopelessness, and despair linked to food insecurity.

OBJECTIVES

This study aimed to investigate the experiences with and perceived effects of a household-level income-generating agricultural intervention on the psychological well-being of adolescent girls in human immunodeficiency virus (HIV)-affected households in southwestern Kenya.

METHODS

We conducted 62 in-depth interviews with HIV-affected adolescent girls and caregiver dyads in Adolescent Shamba Maisha (NCT03741634), a sub-study of adolescent girls and caregivers with a household member participating in Shamba Maisha (NCT01548599), a multisectoral agricultural and finance intervention trial aimed to improve food security and HIV health indicators. Participants were purposively sampled to ensure diversity in terms of age and location. Data were audiotaped, transcribed, translated, and uploaded into Dedoose (Sociocultural Research Consultants, LLC) software for management. Data were analyzed thematically based on reports from Dedoose.

RESULTS

We found evidence that a household-level structural intervention aimed at increasing food and financial security among persons living with HIV can contribute to better psychological well-being among adolescent girls residing in these households. The intervention also affected: 1) reduction of social isolation, 2) reduction of shame and stigma, 3) increased attendance and concentration in school, 4) improved caregiver mental health, and 5) reduced parental aggression and improved household communication. These associations were reported more commonly among those in the intervention arm than the control arm.

CONCLUSIONS

This study extends existing research by demonstrating how multisectoral structural interventions delivered at a household level can improve the psychological well-being of adolescents. We recommend that future research test livelihood interventions designed specifically for adolescent girls that integrate food-security interventions with other elements to address the social and psychological consequences of food insecurity holistically. This trial was registered at clinicaltrials.gov as NCT03741634.

Comparing the effect of a multisectoral agricultural intervention on HIV-related health outcomes between widowed and married women

INTRODUCTION

Widowed women make up 18-40% of the 12 million women living with HIV in eastern and southern Africa. Widowhood has also been associated with greater HIV morbidity and mortality. We compared the effectiveness of a multisectoral climate adaptive agricultural livelihood intervention (called Shamba Maisha) on food insecurity, and HIV related health outcomes among widowed and married women living with HIV in western Kenya.

METHODS

We implemented Shamba Maisha (NCT02815579) using a cluster-randomized control trial design. The intervention arm received an US$175 in-kind loan to purchase a micro-irrigation pump, seeds, and fertilizer, and received eight training sessions on sustainable agriculture and financial management. Study outcomes were measured every 6 months over a 24-month follow-up period and trends in outcomes assessed using multilevel mixed-effects models.

RESULTS

The trial enrolled 232 (61.5%) married and 145 (38.5%) widowed women. Widowed women (mean age 42.8 ± 8.4 years) were older than married women (35.8 ± 9.0 years) (p < 0.01). Almost all widowed women (97.2%) self-identified as household heads compared to 10.8% of married women. Comparing widowed vs married women, reduction in food insecurity (-3.13, 95%CI -4.42, -1.84 vs. -3.08, 95%CI -4.15, -2.02), depressive symptoms (-0.21, 95%CI -0.36, -0.07 vs. -0.19, 95%CI -0.29, -0.08), internalized stigma (-0.33, 95%CI -0.55, -0.11 vs. -0.38, 95%CI -0.57, -0.19), and anticipated stigma (-0.46 95%CI -0.65, -0.28 vs. -0.35, 95%CI -0.50, -0.21) was similar for both groups. In contrast, improvements in social support (-2.22, 95%CI -3.85, -0.59 vs. -4.00, 95%CI -5.16, -2.84; p = 0.08) and reduction in enacted stigma (0.01, 95%CI -0.06, 0.08 vs. -0.14, 95%CI -0.20, -0.09; p < 0.01) were weaker for widowed than married women.

CONCLUSIONS

Our study is among the first comparing the effect of a livelihood intervention on HIV health outcomes among widowed and married women. Widowed women experienced similar benefits as married women on individual-level outcomes, but weaker benefit on outcomes dependent on their external environment like enacted stigma and social support. Future trials and programs targeting widowed women should bolster stigma reduction and social support.

Analyzing fast and slow: Combining traditional and rapid qualitative analysis to meet multiple objectives of a complex transnational study

Much of the methodological literature on rapid qualitative analysis describes processes used by a relatively small number of researchers focusing on one study site and using rapid analysis to replace a traditional analytical approach. In this paper, we describe the experiences of a transnational research consortium integrating both rapid and traditional qualitative analysis approaches to develop social theory while also informing program design. Research was conducted by the Innovations for Choice and Autonomy (ICAN) consortium, which seeks to understand how self-injection of the contraceptive subcutaneous depot medroxyprogesterone acetate (DMPA-SC) can be implemented in a way that best meets women's needs, as defined by women themselves. Consortium members are based in Kenya, Uganda, Malawi, Nigeria, and the United States. Data for the ICAN study was collected in all four countries in sub-Saharan Africa. In order to both illuminate social phenomena across study sites and inform the program design component of the study, researchers developed tools meant to gather both in-depth information about women's contraceptive decision-making and data targeted specifically to program design during the formative qualitative phase of the study. Using these two bodies of data, researchers then simultaneously conducted both a traditional qualitative and rapid analysis to meet multiple study objectives. To complete the traditional analysis, researchers coded interview transcripts and kept analytical memos, while also drawing on data collected by tools developed for the rapid analysis. Rapid analysis consisted of simultaneously collecting data and reviewing notes developed specifically for this analysis. We conclude that integrating traditional and rapid qualitative analysis enabled us to meet the needs of a complex transnational study with the added benefit of grounding our program design work in more robust primary data than normally is available for studies using a human-centered design approach to intervention development. However, the realities of conducting a multi-faceted study across multiple countries and contexts made truly "rapid" analysis challenging.

The Impact of Land Tenure Security on a Livelihood Intervention for People Living with HIV in Western Kenya

Few studies have explored land access, a structural driver of health, and women's participation in livelihood interventions to improve food security and HIV outcomes. This qualitative study, embedded within Shamba Maisha (NCT02815579)-a randomized controlled trial (RCT) examining the impact of a multisectoral intervention among farmers living with HIV in western Kenya-sought to explore the influence of perceived access to and control of land on agricultural productivity, investments, and benefits. Thirty in-depth interviews (IDIs) were conducted with purposively sampled men and women, 3 to 6 months after receiving intervention inputs; data were deductively and inductively coded and analyzed. Farming practices and participation in Shamba Maisha were dependent on land tenure and participants' perceived strength of claim over their land, with participants who perceived themselves to be land insecure less likely to make long-term agricultural investments. Land tenure was influenced by a number of factors and posed unique challenges for women which negatively impacted uptake and success in the intervention. Data underscore the importance of secure land tenure for the success of similar interventions, especially for women; future interventions should integrate land security programming for improved outcomes for all.

Body Composition Trajectories During the First 23 Months of Life Differ by HIV Exposure Among Infants in Western Kenya: A Prospective Study

BACKGROUND

Infants who are HIV-exposed and uninfected have suboptimal growth patterns compared to those who are HIV-unexposed and uninfected. However, little is known about how these patterns persist beyond 1 year of life.

OBJECTIVES

This study aimed to examine whether infant body composition and growth trajectories differed by HIV exposure during the first 2 years of life among Kenyan infants using advanced growth modeling.

METHODS

Repeated infant body composition and growth measurements (mean: 6; range: 2-7) were obtained from 6 weeks to 23 months in the Pith Moromo cohort in Western Kenya (n = 295, 50% HIV-exposed and uninfected, 50% male). Body composition trajectory groups were fitted using latent class mixed modeling (LCMM) and associations between HIV exposure and growth trajectories were examined using logistic regression analysis.

RESULTS

All infants exhibited poor growth. However, HIV-exposed infants generally grew suboptimally than unexposed infants. Across all body composition models except for the sum of skinfolds, HIV-exposed infants had a higher likelihood of belonging to the suboptimal growth groups identified by LCMM than the HIV-unexposed infants. Notably, HIV-exposed infants were 3.3 times more likely (95% CI: 1.5-7.4) to belong to the length-for-age z-score growth class that remained at a z-score of < -2, indicating stunted growth. HIV-exposed infants were also 2.6 times more likely (95% CI: 1.2-5.4) to belong to the weight-for-length-for-age z-score growth class that remained between 0 and -1, and were 4.2 times more likely (95% CI: 1.9-9.3) to belong to the weight-for-age z-score growth class that indicated poor weight gain besides stunted linear growth.

CONCLUSIONS

In a cohort of Kenyan infants, HIV-exposed infants grew suboptimally compared to HIV-unexposed infants beyond 1 year of age. These growth patterns and longer-term effects should be further investigated to support the ongoing efforts to reduce early-life HIV exposure-related health disparities.

Finding the missing children for TB care and prevention in Kenya

SETTING: One hundred high TB burden facilities in nine counties in Kenya.OBJECTIVES: 1) To increase uptake of TB preventive therapy (TPT) among child contacts aged <5 years, and 2) to increase TB diagnosis in children aged <15 years presenting to health facilities for routine care.DESIGN: For objective 1, a clinic-based child contact management strategy incorporating transport/healthcare cost reimbursement, monitoring and evaluation tools, and healthcare worker education was utilized. For objective 2, community health screeners were established in pediatric outpatient departments to perform verbal screening, flagging symptomatic children for further evaluation.RESULTS: Over 15 months, identification of 8,060 individuals diagnosed with bacteriologically confirmed TB led to 2,022 child contacts. Of these, 1,848 (91%) were evaluated; 149 (8%) were diagnosed with TB disease, leaving 1,699 (92%) eligible for TPT; 1,613 (95%) initiated TPT and 1,335 (83%) completed TPT. In outpatient settings, 140,444 children were screened; 54,236 (39%) had at least two TB symptoms; 2,395 (4%) were diagnosed with TB diseaseCONCLUSION: Health system strengthening supporting a clinic-based child contact management program increased the number of children initiating TPT. Systematic screening in outpatient clinics can lead to increased TB case notifications; however, optimal screening tools and clearer diagnostic pathways for the evaluation of these children are needed.

Effect of a Multisectoral Agricultural Intervention on HIV Health Outcomes Among Adults in Kenya: A Cluster Randomized Clinical Trial

Importance

Food insecurity and HIV health outcomes are linked through nutritional, mental health, and health behavior pathways.

Objective

To examine the effects of a multisectoral agriculture and livelihood intervention on HIV viral suppression and nutritional, mental health, and behavioral outcomes among HIV-positive adults prescribed antiretroviral therapy (ART).

Design, Setting, and Participants

This cluster randomized clinical trial was performed in 8 pairs of health facilities in Kenya. Participants were 18 years or older, living with HIV, and receiving ART for longer than 6 months; had moderate to severe food insecurity; and had access to arable land and surface water and/or shallow aquifers. Participants were followed up every 6 months for 24 months. Data were collected from June 23, 2016, to June 13, 2017, with follow-up completed by December 16, 2019. Data were analyzed from June 25 to August 31, 2020, using intention-to-treat and per-protocol methods.

Interventions

A loan to purchase a human-powered irrigation pump, fertilizer, seeds, and pesticides combined with the provision of training in sustainable agriculture and financial literacy.

Main Outcomes and Measures

The primary outcome was the relative change from baseline to the end of follow-up in viral load suppression (≤200 copies/mL) compared between study groups using difference-in-differences analyses. Secondary outcomes included clinic attendance, ART adherence, food insecurity, depression, self-confidence, and social support.

Results

A total of 720 participants were enrolled (396 women [55.0%]; mean [SD] age, 40.38 [9.12] years), including 366 in the intervention group and 354 in the control group. Retention included 677 (94.0%) at the 24-month visit. HIV viral suppression improved in both groups from baseline to end of follow-up from 314 of 366 (85.8%) to 327 of 344 (95.1%) in the intervention group and from 291 of 353 (82.4%) to 314 of 333 (94.3%) in the control group (P = .86). Food insecurity decreased more in the intervention than the control group (difference in linear trend, -3.54 [95% CI, -4.16 to -2.92]). Proportions of those with depression during the 24-month follow-up period declined more in the intervention group (from 169 of 365 [46.3%] to 36 of 344 [10.5%]) than the control group (106 of 354 [29.9%] to 41 of 333 [12.3%]; difference in trend, -0.83 [95% CI, -1.45 to -0.20]). Self-confidence improved more in the intervention than control group (difference in trend, -0.37 [95% CI, -0.59 to -0.15]; P = .001), as did social support (difference in trend, -3.63 [95% CI, -4.30 to -2.95]; P < .001).

Conclusions and Relevance

In this cluster randomized trial, the multisectoral agricultural intervention led to demonstrable health and other benefits; however, it was not possible to detect additional effects of the intervention on HIV clinical indicators. Agricultural interventions that improve productivity and livelihoods hold promise as a way of addressing food insecurity and the underpinnings of poor health among people living with HIV in resource-limited settings.

Survival probability and factors associated with time to loss to follow-up and mortality among patients on antiretroviral treatment in central Kenya

BACKGROUND

Retention of patients who are receiving antiretroviral therapy (ART) remains a challenge especially in the setting of rapid expansion of HIV services. Retention in care remains vital to the HIV care continuum, and has been associated with viral suppression and improved survival. This study aimed to ascertain survival rates, time to loss to follow-up (LTFU) or mortality events and factors associated with time to LTFU or mortality among patients enrolled on antiretroviral therapy at health facilities in central Kenya.

METHODS

This was a retrospective cohort study among patients initiated on ART between 2004 and 2012 in central Kenya. Demographic characteristics, clinical characteristics and outcomes data were analyzed using Stata version 15.1. Competing risks regression analysis and cummulative incidence functions were used to estimate survival.

RESULTS

A total of 31,346 patients were included, of whom 65.6% were female, 76.0% were aged between 20 and 50 years old, and 38.9% were diagnosed at WHO stage III. At 36 months, overall retention was 68.8%, LTFU was 27.1%, and mortality was 4.1%. The total person-years of follow up was 74,986. The incidence rate of LTFU was 9.99 per 100 person years for a total of 9383.25 person-years of follow up. The mortality rate was 1.25 per 100 person years for a total of 875.5 person-years among those who died. The median time to LTFU was 11 months (IQR 3-22) while median time to death was 3 months (IQR 0-13). Men, unmarried patients, patients presenting with advanced HIV, not on TB treatment, and enrolled into the HIV program in later cohorts, had a shorter time to mortality and LTFU.

CONCLUSION

Our study demonstrated evidence of scale-up of HIV treatment programs in central Kenya. While most patients were enrolled at an advanced WHO clinical stage, overall 36-month mortality remained low, but occurred earlier during follow-up. Cohort LTFU at 36-months reduced in later years with the losses occurring within the 1st year of follow-up. Predictors of early mortality and LTFU included being male, single, separated or divorced, advanced WHO clinical stage, and among patients not on TB treatment.

TB training in Kenya: building capacity for care and prevention

BACKGROUND: Devolution of healthcare services in Kenya resulted in a large number of newly recruited tuberculosis (TB) coordinators. We describe a unique collaboration between a national tuberculosis program (NTP), a local, and an international non-governmental organization to build human resource capacity in TB care and prevention.METHODS: From 2016 to 2021, the Kenya Division of National Tuberculosis, Leprosy and Lung Disease Program, Centre for Health Solutions-Kenya, and the International Union Against Tuberculosis and Lung Disease developed and conducted a series of 7-day training courses. A key focus of training was the introduction of TBData4Action, an approach involving the local use of routinely available data to strengthen decision-making and support supervision.RESULTS: Implementation outcomes included training 331 (96%) coordinators out of 344, representing all 47 counties, 37 national officers and 21 other stakeholders using the country-tailored curriculum, including hands-on group work by county teams and field practicals. Thirty-five national facilitators were identified and mentored as local faculty. Training costs were reduced by 75% compared with international alternatives.CONCLUSION: The collaboration resulted in the training of the majority of the coordinators in a standardized approach to TB care. A sustainable approach to capacity building in local data use was found feasible; the model could be adapted by other NTPs.

Water Insecurity is Associated with Lack of Viral Suppression and Greater Odds of AIDS-Defining Illnesses Among Adults with HIV in Western Kenya

Reliable access to safe and acceptable water in sufficient quantities (i.e., water security) is important for medication adherence and limiting pathogen exposure, yet prior studies have only considered the role of food security as a social determinant of HIV-related health. Therefore, the objective of this analysis was to assess the relationships between household water insecurity and HIV-related outcomes among adults living with HIV in western Kenya (N = 716). We conducted a cross-sectional analysis of baseline data from Shamba Maisha (NCT02815579), a cluster randomized controlled trial of a multisectoral agricultural and asset loan intervention. Baseline data were collected from June 2016 to December 2017. We assessed associations between water insecurity and HIV-related outcomes, adjusting for clinical and behavioral confounders, including food insecurity. Each five-unit higher household water insecurity score (range: 0-51) was associated with 1.21 higher odds of having a viral load ≥ 1000 copies/mL (95% CI 1.07, 1.36) and 1.26 higher odds of AIDS-defining illness (95% CI 1.11, 1.42). Household water insecurity was not associated with CD4 cell count (B: 0.27; 95% CI -3.59, 13.05). HIV treatment and support programs should consider assessing and addressing water insecurity in addition to food insecurity to optimize HIV outcomes.

Temporal trends in pre-ART patient characteristics and outcomes before the test and treat era in Central Kenya

BACKGROUND

Retention of patients who did not initiate antiretroviral therapy (ART) has been persistently low compared to those who initiated ART. Understanding the temporal trends in clinical outcomes prior to ART initiation may inform interventions targeting patients who do not initiate ART immediately after diagnosis.

METHODS

A retrospective cohort analysis of known HIV-infected patients who did not initiate ART from healthcare facilities in Central Kenya was done to investigate temporal trends in characteristics, retention, and mortality outcomes. The data were sourced from the Comprehensive Care Clinic Patient Application Database (CPAD) and IQ care electronic patient-level databases for those enrolled between 2004 and 2014.

RESULTS

A total of 13,779 HIV-infected patients were assessed, of whom 30.7% were men.There were statisitically significant differences in temporal trends relating to marital status, WHO clinical stage, and tuberculosis (TB) status from 2004 to 2014. The proportion of widowed patients decreased from 9.1 to 6.0%. By WHO clinical stage at enrollment in program, those in WHO stage I increased over time from 8.7 to 43.1%, while those in WHO stage III and IV reduced from 28.5 to 10.8% and 4.0 to 1.1% respectively. Those on TB treatment during their last known visit reduced from 8.3 to 3.9% while those with no TB signs increased from 58.5 to 86.8%. Trends in 6 and 12 month retention in the program, loss to follow-up (LTFU) and mortality were statistically significant. At 6 months, program retention ranged between 36.0% in 2004 to a high of 54.1% in 2013. LTFU at 6 months remained around 50.0% for most of the cohorts, while mortality at 6 months was 7.5% in 2004 but reduced to 3.8% in 2014. At 12 months, LTFU was above 50.0% across all the cohorts while mortality rate reached 3.9% in 2014.

CONCLUSION

Trends in pre ART enrollment suggested higher enrollment among patients who were women and at earlier WHO clinical stages. Retention and mortality outcomes at 6 and 12 months generally improved over the 11 year follow-up period, though dipped as enrollment in asymptomatic disease stage increased.

Household Water and Food Insecurity Are Positively Associated with Poor Mental and Physical Health among Adults Living with HIV in Western Kenya

BACKGROUND

Household food insecurity (FI) and water insecurity (WI) are prevalent public health issues that can co-occur. Few studies have concurrently assessed their associations with health outcomes, particularly among people living with HIV.

OBJECTIVES

We aimed to investigate the associations between FI and WI and how they relate to physical and mental health.

METHODS

Food-insecure adult smallholder farmers living with HIV in western Kenya were recruited to participate in a cluster-randomized controlled trial of a multisectoral agricultural and asset loan intervention. We used baseline data on experiences of FI (using the Household Food Insecurity Access Scale, range: 0-27) and WI (using a modified scale developed for this region, range: 0-51) in the prior month (n = 716). Outcomes included probable depression (using the Hopkins Symptom Checklist), fatigue and diarrhea in the prior month, and overall mental and physical health (using the Medical Outcomes Study HIV Health Survey, range: 0-100). We first assessed Pearson correlations between FI, WI, and sociodemographic characteristics. We then developed 3 regressions for each health outcome (control variables and FI; control variables and WI; control variables, FI, and WI) and compared model fit indexes.

RESULTS

Correlations between household FI, WI, and wealth were low, meaning they measure distinct constructs. FI and WI were associated with numerous physical and mental health outcomes; accounting for both resource insecurities typically provided the best model fit. For instance, when controlling for FI, each 10-point higher WI score was associated with a 6.42-point lower physical health score (P < 0.001) and 2.92 times greater odds of probable depression (P < 0.001).

CONCLUSIONS

Assessing both FI and WI is important for correctly estimating their relation with health outcomes. Interventions that address food- and water-related issues among persons living with HIV concurrently will likely be more effective at improving health than those addressing a single resource insecurity. This trial was registered at clinicaltrials.gov as NCT02815579.

Prevalence and Covariates of Food Insecurity Across the First 1000 Days Among Women of Mixed HIV Status in Western Kenya: A Longitudinal Perspective

BACKGROUND

Food insecurity (FI) is common globally and can have lifelong consequences. However, few studies have longitudinally examined how FI varies across gestation and the postpartum period ("the first 1000 days"); none have explored this in sub-Saharan Africa or in the context of HIV.

OBJECTIVE

To assess the prevalence and covariates of FI in the first 1000 days among Kenyan women.

METHODS

All pregnant women attending 7 clinics in western Kenya (n = 1247) were screened for HIV and FI (Individual Food Insecurity Access Scale) between September 2014 and June 2015. A subset of women (n = 371) was recruited into an observational cohort study and surveyed 11 times through 2 years postpartum (NCT02974972, NCT02979418). Data on FI, sociodemographics, and health were repeatedly collected. Severe FI was modeled using multilevel, mixed-effects logistic regressions (n = 346).

RESULTS

Of the 1247 pregnant women screened, 76.5% were severely food insecure in the prior month. Further, the prevalence of severe FI was higher among women living with HIV than those without (82.6% vs 74.6%, P < .05). In the cohort, the odds of being severely food insecure decreased monotonically after delivery. Each point higher on the Center for Epidemiologic Studies-Depression scale was associated with 1.08 times greater odds of being severely food insecure (95% CI: 1.05-1.10); each point higher on the Duke/UNC Functional Social Support Scale was associated with 0.97 lower odds of severe FI (95% CI: 0.94-0.99).

CONCLUSIONS

Severe FI is prevalent during the first 1000 days in western Kenya. Services to mitigate the far-reaching consequences of this modifiable risk should be considered.

Food Insecurity and Intimate Partner Violence Among HIV-Positive Individuals in Rural Kenya

INTRODUCTION

Intimate partner violence and food insecurity are both structural drivers of HIV acquisition, care, and treatment, but little is known about how the 2 conditions intersect in the lives of those already living with HIV.

METHODS

This study examined cross-sectional baseline data (collected in January 2016-December 2017) from an ongoing trial in southwestern Kenya. Trained interviewers asked enrolled participants living with HIV aged 18-60 years about household food insecurity (using the Household Food Insecurity Access Scale), intimate partner violence (using an adapted WHO multicountry study instrument), and sociodemographics. Negative binomial regression was used to examine the association between food insecurity and partner violence victimization (among women) or perpetration (among men). Secondary data were analyzed in August 2019-March 2020.

RESULTS

Of 720 participants, more than half of women reported experiencing intimate partner violence (57.6%) and most men reported perpetrating it (58.4%). Participants reporting any partner violence had higher Household Food Insecurity Access Scale scores (21.8) compared with those reporting no violence (21.3, p=0.02). Each categorical change in food insecurity (mild, moderate, severe) was associated with a 41% increased risk of an additional partner violence episode. In models controlling for relationship status, wealth, season of interview (lean versus not lean), and baseline physical health, each 1-point increase in food insecurity was associated with a 6% higher risk of violence victimization among women and 4% greater risk of men perpetrating partner violence.

CONCLUSIONS

This study highlights the interconnected nature of intimate partner violence and food insecurity among women and men living with HIV. This relationship suggests that enhancing food security may be a useful intervention strategy to prevent intimate partner violence and improve HIV-related health outcomes.

Presence of Older Adolescents in the Household is Associated with Depressive Symptoms Among Women Living with HIV in Kenya

The objective of this study was to determine the association between the number of adolescents in a household and depressive symptoms among adult caregivers living with HIV. We examined cross-sectional baseline data among adults enrolled in the Shamba Maisha multisectoral agricultural intervention (n = 705) in the Nyanza region of Kenya (NCT02815579). Each additional adolescent 15-19 years in a household was associated with a 1.35 (95% CI 1.06-1.71) higher odds of depressive symptoms among women, but not men, adjusting for potential confounders. Interventions to support the mental health of adults living with HIV may target women caring for dependent adolescents 15-19 years.

Social Support Mitigates Negative Impact of Food Insecurity on Antiretroviral Adherence Among Postpartum Women in Western Kenya

Food insecurity (FI), low social support, and low health-related quality of life (HRQoL) are associated with self-reported nonadherence to antiretroviral therapy (ART) among postpartum women, but these relationships have not been evaluated using objective adherence indicators. Hair samples were therefore analyzed among 83 postpartum Kenyan women living with HIV on efavirenz and nevirapine ART drug regimens in an observational cohort (NCT02974972). FI (0-27), social support (0-40), and HRQoL (8-40) in the prior month were also assessed. In multivariable models, each point increase in FI and decrease in HRQoL were associated with a 45.1% (95% CI: -64.3%, -15.6%) and 10.5% decrease (95% CI: 1.0%, 22.1%) in hair ART drug concentrations respectively, when social support was held constant. A significant interaction between social support and FI (β = 0.02, p = 0.017) indicated that greater social support was predicted to mitigate the negative impacts of FI on ART adherence. Addressing these modifiable barriers could improve ART adherence during this critical period.

"When I Eat Well, I Will Be Healthy, and the Child Will Also Be Healthy": Maternal Nutrition among HIV-Infected Women Enrolled in a Livelihood Intervention in Western Kenya

BACKGROUND

Food insecurity remains a major obstacle to achieving health and well-being for individuals living with HIV in western Kenya. Studies have shown that pregnant women are vulnerable to experiencing food insecurity worldwide, with significant consequences for both maternal and child health. The Shamba Maisha cluster randomized controlled trial in western Kenya (which means "farming for life" in Swahili) tested the effects of a multisectoral livelihood intervention consisting of agricultural and finance trainings, farm inputs, and a loan on health and food security among 746 farmers living with HIV in Kisumu, Homa Bay, and Migori Counties.

OBJECTIVES

We conducted a qualitative substudy within the Shamba Maisha trial to understand the experiences and perspectives of pregnant women living with HIV enrolled in the trial.

METHODS

Thirty women who had experienced a pregnancy during the Shamba Maisha study period, comprising 20 women in the intervention arm and 10 women in the control arm, completed in-depth interviews using a semistructured interview guide.

RESULTS

Intervention participants interviewed noted improvements in maternal nutrition compared with previous pregnancies, which they attributed to the livelihood intervention. Key identified pathways to improved nutrition included improved access to vegetables, increased variety of diet through vegetable sales, and improved nutritional awareness. Women in the intervention arm also perceived increased weight gain compared with prior pregnancies and increased strength and energy throughout pregnancy.

CONCLUSIONS

Livelihood interventions represent a promising solution to alleviate food insecurity for pregnant women in order to improve maternal and child health outcomes.This trial was registered at clinicaltrials.gov as NCT02815579.

Narratives of Women Using a 24-Hour Ride-Hailing Transport System to Increase Access and Utilization of Maternal and Newborn Health Services in Rural Western Kenya: A Qualitative Study

Between 1990 and 2015, Kenya had a 0.9% annual reduction in maternal mortality, one of the lowest reductions globally. This slow decline was linked to the relatively low utilization of delivery services. We designed a mobile phone-enhanced 24-hour transport navigation system coupled with personalized and interactive gestation-based text messages (MAccess) to address maternal child health service utilization. The primary purpose of this analysis is to explore the ways in which pregnant and postnatal women made decisions regarding care-seeking for pregnancy and childbirth services, the processes of getting care from home to the hospital as well their perceptions on how the MAccess intervention affected their pregnancy and childbirth care-seeking and utilization experience. We conducted semistructured, individual interviews with 18 postpartum women. Participants were purposively sampled. Interviews were audiotaped, transcribed, and analyzed using thematic analysis. For participants in this study, all three delays interacted in a complex manner to affect women's utilization of pregnancy and childbirth services. Even though women were aware of the benefits of skilled birth attendance, other health system factors such as opening hours, or health workers' attitudes still deterred women from delivering in health facilities. The MAccess innovation was highly acceptable to women throughout pregnancy and childbirth and helped them navigate the complex and layered individual, infrastructural, and health system factors that put them at risk of adverse maternal and newborn outcomes. These findings emphasize that an integrated approach, which addresses all delays simultaneously, is important for reducing perinatal morbidity and mortality.

Increased Social Support Mitigates the Negative Impact of Food Insecurity on Antiretroviral Adherence Among Postpartum Women in Western Kenya (P04-126-19)

Objectives

Antiretroviral (ARV) adherence is a strong predictor of improved health outcomes and treatment effectiveness among persons living with HIV. Food insecurity and low social support are have been demonstrated to predict reported nonadherence among pregnant women, but the relationship has not been evaluated using an objective indicator of adherence. Therefore, we explored the impacts of social support and food insecurity on ARV adherence using ARV drug concentrations in hair among postpartum Kenyan women living with HIV.

Methods

Hair samples were collected from 83 HIV + women, a subset from an observational pregnancy cohort study (NCT02974972), on Efavirenz (n = 58) and Nevirapine (n = 25)-based ARVs at nine months postpartum. Hair ARV concentrations were log transformed to approximate a normal distribution. Food insecurity [Individual Food Insecurity Access Scale (IFIAS, 0–27)], social support (Perceived Social Support Scale, 0–40), and quality of life (Short Form 8 Health Survey, 0–40] were recalled for the prior month. These covariables, along with sociodemographic characteristics, were included in a multivariable linear regression model (P < 0.2) and eliminated using a backward stepwise approach (P < 0.1).

Results

Mean IFIAS score was 10.0 (± 5.2). Lower food insecurity and greater quality of life were significantly associated with higher hair ARV concentrations. Each point increase in IFIAS and decrease in quality of life was associated with a 13.4% decrease (95%CI: −0.23, −0.05) and 15.7% decrease (95%CI: 0.06, 0.23) in hair levels, respectively. Social support was not significantly associated with ARV adherence in bivariate analysis, but did buffer against the negative impacts of food insecurity on ARV adherence in the final multivariable model (Figure 1).

Conclusions

This study demonstrates that low food insecurity is significantly associated with higher ARV adherence among postpartum women using an objective biomarker, and that social support can buffer the negative effect of food insecurity on adherence. Interventions addressing these modifiable barriers to ARV adherence should be explored to improve adherence among HIV + postpartum women.

Effects of an expanded Uber-like transport system on access to and use of maternal and newborn health services: findings of a prospective cohort study in Homa Bay, Kenya

INTRODUCTION

Kenya's progress towards reducing maternal and neonatal deaths is at present 'insufficient'. These deaths could be prevented if the three delays, that is, in deciding to seek healthcare (delay 1), in accessing formal healthcare (delay 2) and in receiving quality healthcare (delay 3), are comprehensively addressed. We designed a mobile phone enhanced 24 hours Uber-like transport navigation system coupled with personalised and interactive gestation-based text messages to address these delays. Our main objective was to evaluate the impact of this intervention on women's adherence to recommended antenatal (ANC) and postnatal care (PNC) regimes and facility birth.

METHODS

We conducted a prospective cohort study. Women were eligible to participate in the study if they were 15 years or older and less than 28 weeks gestation. We defined cases as those who received the standard of care plus the intervention and the control group as those who received the standard of care only. For analysis, we used logistic regression analysis and report crude and adjusted OR (aOR) and 95 % CI.

RESULTS

Cases (women who received the intervention) had five times higher odds of having four or more ANC visits (aOR=4.7, 95% CI 3.20 to 7.09), three times higher odds of taking between 30 and 60 min to reach a health facility for delivery (aOR=3.14, 95% CI 2.37 to 4.15) and four times higher odds of undergoing at least four PNC visits (aOR=4.10, 95% CI 3.11 to 5.36).

CONCLUSION

An enhanced community-based Uber-like transport navigation system coupled with personalised and interactive gestation-based text messages significantly increased the utilisation of ANC and PNC services as well as shortened the time taken to reach an appropriate facility for delivery compared with standard care.

Empowering HIV-infected women in low-resource settings: A pilot study evaluating a patient-centered HIV prevention strategy for reproduction in Kisumu, Kenya

BACKGROUND

Female positive/male negative HIV-serodiscordant couples express a desire for children and may engage in condomless sex to become pregnant. Current guidelines recommend antiretroviral treatment in HIV-serodiscordant couples, yet HIV RNA viral suppression may not be routinely assessed or guaranteed and pre-exposure prophylaxis may not be readily available. Therefore, options for becoming pregnant while limiting HIV transmission should be offered and accessible to HIV-affected couples desiring children.

METHODS

A prospective pilot study of female positive/male negative HIV-serodiscordant couples desiring children was conducted to evaluate the acceptability, feasibility, and effectiveness of timed vaginal insemination. Eligible women were 18-34 years with regular menses. Prior to timed vaginal insemination, couples were observed for two months, and tested and treated for sexually transmitted infections. Timed vaginal insemination was performed for up to six menstrual cycles. A fertility evaluation and HIV RNA viral load assessment was offered to couples who did not become pregnant.

FINDINGS

Forty female positive/male negative HIV-serodiscordant couples were enrolled; 17 (42.5%) exited prior to timed vaginal insemination. Twenty-three couples (57.5%) were introduced to timed vaginal insemination; eight (34.8%) achieved pregnancy, and six live births resulted without a case of HIV transmission. Seven couples completed a fertility evaluation. Four women had no demonstrable tubal patency bilaterally; one male partner had decreased sperm motility. Five women had unilateral/bilateral tubal patency; and seven women had an HIV RNA viral load (≥ 400 copies/mL).

CONCLUSION

Timed vaginal insemination is an acceptable, feasible, and effective method for attempting pregnancy. Given the desire for children and inadequate viral suppression, interventions to support safely becoming pregnant should be integrated into HIV prevention programs.

'I know how stressful it is to lack water!' Exploring the lived experiences of household water insecurity among pregnant and postpartum women in western Kenya

There is rapidly evolving literature on water insecurity in the general adult population, but the role of water insecurity during the vulnerable periods of pregnancy and postpartum, or in the context of HIV, has been largely overlooked. Therefore, we conducted an exploratory study, using Go Along interviews, photo-elicitation interviews, and pile sorts with 40 pregnant and postpartum Kenyan women living in an area of high HIV prevalence. We sought to (1) describe their lived experiences of water acquisition, prioritisation, and use and (2) explore the consequences of water insecurity. The results suggest that water insecurity is particularly acute in this period, and impacts women in far-reaching and unexpected ways. We propose a broader conceptualisation of water insecurity to include consideration of the consequences of water insecurity for maternal and infant psychosocial and physical health, nutrition, and economic well-being.

HIV infection and increased food insecurity are associated with adverse body composition changes among pregnant and lactating Kenyan women

BACKGROUND/OBJECTIVES

Body composition changes markedly during reproduction. In sub-Saharan Africa, impacts of HIV infection on body composition across pregnancy and lactation in the context of Option B+ antiretroviral therapy are unknown. Therefore, we sought to evaluate the role of HIV infection on body composition during pregnancy and lactation among Kenyan women.

SUBJECTS/METHODS

A cohort of pregnant women (n = 333; 50.5% HIV+, receiving ART) were enrolled at seven clinics in western Kenya. Two prenatal (mean ± SD: 23.6 ± 4.4 and 33.4 ± 2.0 weeks gestation) and three postpartum (6, 14, and 36 weeks) measurements included: individual-level food insecurity, height, weight, fat mass (FM), and fat-free mass (FFM) by bioimpedance analysis (BIA), mid-upper arm circumference (MUAC), and triceps skinfold (TSF), allowing for AMA (arm muscle area) and AFA (arm fat area) derivation. Multivariable longitudinal regression models were used to relate HIV to body composition changes.

RESULTS

In longitudinal models, HIV-infected women had lower weight (ß = -3.0 kg, p = 0.003), fat mass (ß = -1.5 kg, p = 0.02), fat-free mass (ß = -1.5 kg, p = 0.01), TSF (ß = -2.6 mm, p < 0.001), AFA (ß = -3.9 cm³, p < 0.001), and MUAC (ß = -1.0 cm, p = 0.001), but not AMA (p = 0.34), across all observations. Food insecurity was inversely associated with AMA and MUAC postpartum (AMA ß-range = -0.47 to -0.92 cm³; MUAC ß-range = -0.09 to -0.15 cm, all p < 0.05).

CONCLUSIONS

HIV infection was associated with lower weight, fat mass, fat-free mass, TSF, AFA, and MUAC values during pregnancy and lactation, while food insecurity was intermittently associated with body composition. This suggests that pregnant and lactating women living with HIV and food insecurity could benefit from nutritional support.

A novel household water insecurity scale: Procedures and psychometric analysis among postpartum women in western Kenya

Our ability to measure household-level food insecurity has revealed its critical role in a range of physical, psychosocial, and health outcomes. Currently, there is no analogous, standardized instrument for quantifying household-level water insecurity, which prevents us from understanding both its prevalence and consequences. Therefore, our objectives were to develop and validate a household water insecurity scale appropriate for use in our cohort in western Kenya. We used a range of qualitative techniques to develop a preliminary set of 29 household water insecurity questions and administered those questions at 15 and 18 months postpartum, concurrent with a suite of other survey modules. These data were complemented by data on quantity of water used and stored, and microbiological quality. Inter-item and item-total correlations were performed to reduce scale items to 20. Exploratory factor and parallel analyses were used to determine the latent factor structure; a unidimensional scale was hypothesized and tested using confirmatory factor and bifactor analyses, along with multiple statistical fit indices. Reliability was assessed using Cronbach’s alpha and the coefficient of stability, which produced a coefficient alpha of 0.97 at 15 and 18 months postpartum and a coefficient of stability of 0.62. Predictive, convergent and discriminant validity of the final household water insecurity scale were supported based on relationships with food insecurity, perceived stress, per capita household water use, and time and money spent acquiring water. The resultant scale is a valid and reliable instrument. It can be used in this setting to test a range of hypotheses about the role of household water insecurity in numerous physical and psychosocial health outcomes, to identify the households most vulnerable to water insecurity, and to evaluate the effects of water-related interventions. To extend its applicability, we encourage efforts to develop a cross-culturally valid scale using robust qualitative and quantitative techniques.

"Men Are in Front at Eating Time, but Not When It Comes to Rearing the Chicken": Unpacking the Gendered Benefits and Costs of Livestock Ownership in Kenya

BACKGROUND

Livestock can promote resilience in low-income communities through a number of pathways. Livestock development programs seek to amplify these benefits but often fail to consider the costs to intended beneficiaries or the effect of prevailing gender norms.

OBJECTIVE

To explore perceptions of livestock ownership among female smallholder livestock keepers in Nyanza Region, Kenya, and unpack how the distribution of livestock benefits and investments varies by gender within households.

METHODS

We used multiple ethnographic techniques, including Photovoice, a photo-elicitation interview method, focus group discussions, and pile sorts, with female smallholder livestock owners (n = 18) participating in an ongoing cohort study. Transcripts were coded using a combination of a priori constructs and grounded theory.

RESULTS

We found that livestock benefited households by providing financial security, food security, social benefits, and human time and labor savings. However, these benefits largely promoted long-term household resilience rather than immediate gains. Livestock ownership also had major costs to household time and labor, which were overwhelmingly borne by women and children. Despite this investment, women had limited livestock ownership rights, decision-making power, control over income, or access to meat.

CONCLUSIONS

Our findings suggest that livestock ownership requires significant investments of household time and labor, which disproportionately burden women. Prevailing gender inequalities may therefore constrain the net benefit of livestock ownership for many women and their households in some contexts. Livestock development programs must assess both program benefits and costs at multiple levels to ensure that women's participation in livestock production leads to improved individual and household outcomes.

Household water insecurity is associated with a range of negative consequences among pregnant Kenyan women of mixed HIV status

Water insecurity (WI) is a serious and worsening problem worldwide, but its role in health outcomes among people living with HIV or pregnant women is unknown. We assessed experiences of WI in a cohort of 323 pregnant Kenyan women of mixed HIV status. The majority (77.7%) had at least one experience of WI in the previous month; it was associated with negative economic, nutrition, disease, and psychosocial outcomes. A standardized cross-culturally valid household WI scale would facilitate assessment of the prevalence and consequences of WI, and increased attention to WI could reveal an overlooked, but modifiable, cause of adverse HIV outcomes.

Impact of family planning health talks by lay health workers on contraceptive knowledge and attitudes among HIV-infected patients in rural Kenya

OBJECTIVE

To determine if a health talk on family planning (FP) by community clinic health assistants (CCHAs) will improve knowledge, attitudes and behavioral intentions about contraception in HIV-infected individuals.

METHODS

A 15-min FP health talk was given by CCHAs in six rural HIV clinics to a sample of 49 HIV-infected men and women. Effects of the health talk were assessed through a questionnaire administered before the health talk and after completion of the participant's clinic visit.

RESULTS

Following the health talk, there was a significant increase in knowledge about contraceptives (p<.0001), side-effects (p<.0001), and method-specific knowledge about IUCDs (p<.001), implants (p<.0001), and injectables (p<.05). Out of 31 women and 18 men enrolled, 14 (45%) women and 6 (33%) men intended to try a new contraceptive. Participant attitudes toward FP were high before and after the health talk (median 4 of 4).

CONCLUSION

A health talk delivered by CCHAs can increase knowledge of contraception and promote the intention to try new more effective contraception among HIV-infected individuals.

PRACTICE IMPLICATIONS

FP health talks administered by lay-health providers to HIV-infected individuals as they wait for HIV services can influence FP knowledge and intention to use FP.
