Project description:IntroductionHigh levels of adherence to antiretroviral therapy (ART) are central to HIV management. The objective of this study was to compare multiple measures of adherence and investigate factors associated with adherence among HIV-infected children in western Kenya.MethodsWe evaluated ART adherence prospectively for six months among HIV-infected children aged ≤14 years attending a large outpatient HIV clinic in Kenya. Adherence was reported using caregiver report, plasma drug concentrations and Medication Event Monitoring Systems (MEMS®). Kappa statistics were used to compare adherence estimates with MEMS®. Logistic regression analyses were performed to assess the association between child, caregiver and household characteristics with dichotomized adherence (MEMS® adherence ≥90% vs. <90%) and MEMS® treatment interruptions of ≥48 hours. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated.ResultsAmong 191 children, mean age at baseline was 8.2 years and 55% were female. Median adherence by MEMS® was 96.3% and improved over the course of follow-up (p<0.01), although 49.5% of children had at least one MEMS® treatment interruption of ≥48 hours. Adherence estimates were highest by caregiver report, and there was poor agreement between MEMS® and other adherence measures (Kappa statistics 0.04-0.37). In multivariable logistic regression, only caregiver-reported missed doses in the past 30 days (OR 1.25, 95% CI 1.14-1.39), late doses in the past seven days (OR 1.14, 95% CI 1.05-1.22) and caregiver-reported problems with getting the child to take ART (OR 1.10, 95% CI 1.01-1.20) were significantly associated with dichotomized MEMS® adherence. The caregivers reporting that ART made the child sick (OR 1.12, 95% CI 1.01-1.25) and reporting difficulties in the community that made giving ART more difficult (e.g. stigma) (OR 1.14, 95% CI 1.02-1.27) were significantly associated with MEMS® treatment interruptions in multivariable logistic regression.ConclusionsNon-adherence in the form of missed and late doses, treatment interruptions of more than 48 hours and sub-therapeutic drug levels were common in this cohort. Adherence varied significantly by adherence measure, suggesting that additional validation of adherence measures is needed. Few factors were consistently associated with non-adherence or treatment interruptions.

Project description: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.

Project description:The triple burden of malnutrition in many low- and middle-income countries (LMICs) is partly a result of changing food environments and a shift from traditional diets to high-calorie Western-style diets. Exploring the relationship between food sources and food- and nutrition-related outcomes is important to understanding how changes in food environments may affect nutrition in LMICs. This study examined associations of household food source with household food insecurity, individual dietary diversity and individual body mass index in Western Kenya. Interview-administered questionnaire and anthropometric data from 493 adults living in 376 randomly-selected households were collected in 2019. Adjusted regression analyses were used to assess the association of food source with measures of food insecurity, dietary diversity and body mass index. Notably, participants that reported rearing domesticated animals for consumption ('own livestock') had lower odds of moderate or severe household food insecurity (odds ratio (OR) = 0.29 (95% CI: 0.09, 0.96)) and those that reported buying food from supermarkets had lower odds of moderate or severe household food insecurity (borderline significant, OR = 0.37 (95% CI: 0.14, 1.00)), increased dietary diversity scores (Poisson coefficient = 0.17 (95% CI: 0.10, 0.24)) and higher odds of achieving minimum dietary diversity (OR = 2.84 (95% CI: 1.79, 4.49)). Our findings provide insight into the relationship between food environments, dietary patterns and nutrition in Kenya, and suggest that interventions that influence household food source may impact the malnutrition burden in this context.

Project description:Food insecurity is a potentially important barrier to the success of antiretroviral therapy (ART) programs in resource-limited settings. We undertook a longitudinal study in rural Uganda to estimate the associations between food insecurity and HIV treatment outcomes.Longitudinal cohort study.Participants were from the Uganda AIDS Rural Treatment Outcomes study and were followed quarterly for blood draws and structured interviews. We measured food insecurity with the validated Household Food Insecurity Access Scale. Our primary outcomes were: ART nonadherence (adherence <90%) measured by visual analog scale; incomplete viral load suppression (>400?copies/ml); and low CD4 T-cell count (<350?cells/?l). We used generalized estimating equations to estimate the associations, adjusting for socio-demographic and clinical variables.We followed 438 participants for a median of 33 months; 78.5% were food insecure at baseline. In adjusted analyses, food insecurity was associated with higher odds of ART nonadherence [adjusted odds ratio (AOR) 1.56, 95% confidence interval (CI) 1.10-2.20, P?<?0.05], incomplete viral suppression (AOR 1.52, 95% CI 1.18-1.96, P?<?0.01), and CD4 T-cell count less than 350 (AOR 1.47, 95% CI 1.24-1.74, P?<?0.01). Adding adherence as a covariate to the latter two models removed the association between food insecurity and viral suppression, but not between food insecurity and CD4 T-cell count.Food insecurity is longitudinally associated with poor HIV outcomes in rural Uganda. Intervention research is needed to determine the extent to which improved food security is causally related to improved HIV outcomes and to identify the most effective policies and programs to improve food security and health.

Project description:ObjectiveWater plays a critical role in the production of food and preparation of nutritious meals, yet few studies have examined the relationship between water and food insecurity. The primary objective of this study, therefore, was to examine how experiences of household water insecurity (HWI) relate to experiences of household food insecurity (HFI) among a pastoralist population living in an arid, water-stressed region of northern Kenya.DesignWe implemented the twelve-item Household Water Insecurity Experiences (HWISE, range 0-36) Scale and the nine-item Household Food Insecurity Access Scale (HFIAS, range 0-27) in a cross-sectional survey to measure HWI and HFI, respectively. Data on socio-demographic characteristics and intake of meat and dairy in the prior week were collected as covariates of interest.SettingNorthern Kenya, June-July 2019.ParticipantsDaasanach pastoralist households (n 136) from seven communities.ResultsIn the prior 4 weeks, 93·4 % and 98·5 % of households had experienced moderate-to-severe HWI and HFI, respectively. Multiple linear regression analyses indicated a strong association between HWI and HFI. Each point higher HWISE score was associated with a 0·44-point (95 % CI: 0·22, 0·66, P = 0·003) higher HFIAS score adjusting for socio-economic status and other covariates.ConclusionsThese findings demonstrate high prevalence and co-occurrence of HWI and HFI among Daasanach pastoralists in northern Kenya. This study highlights the need to address HWI and HFI simultaneously when developing policies and interventions to improve the nutritional well-being of populations whose subsistence is closely tied to water availability and access.

Project description:The health and economic threats posed by the COVID-19 pandemic can be sources of great distress among people living with HIV, which in turn can impact the management of their HIV disease. We examined change in depression from pre- to post-lockdown restrictions and correlates of elevated depressive symptoms, including antiretroviral therapy (ART) adherence. Participants enrolled in a randomized controlled trial of an ART adherence intervention in Uganda. The month-12 follow-up assessment was fully administered just prior to the start of the pandemic-related lockdown in March 2020; at the conclusion of the lockdown three months later, we administered a mixed-methods phone-based assessment. ART adherence was electronically monitored throughout the study period, including during and after the lockdown. Depression was assessed with the 8-item Patient health questionnaire (PHQ-8), on which scores > 9 signify a positive screen for elevated depressive symptoms. A sample of 280 participants completed both the month-12 and post-lockdown assessments. Rates of elevated depressive symptoms nearly tripled from month 12 (n = 17, 6.1%) to the post-lockdown assessment (n = 50, 17.9%; McNemar test < .001). Elevated depressive symptoms at post-lockdown were associated with being female, indicators of economic struggles at month 12 (unemployment, low income, high food insecurity), and lower ART adherence during the 3-month lockdown period [mean of 71.9% (SD = 27.9) vs. 80.8% (SD = 24.1) among those not depressed; p = .041] in bivariate analysis. In multiple regression analysis, higher food insecurity [adj. OR (95% CI) = 4.64 (2.16-9.96)] and perception that the pandemic negatively impacted ART adherence [adj. OR (95% CI) = 1.96 (1.22-3.16)] remained associated with a greater likelihood of elevated depressive symptoms, when other correlates were controlled for. Qualitative data suggested that economic stressors (lack of food, work, and money) were key contributors to elevated depressive symptoms, and these stressors led to missed ART doses because of lack of food and stress induced forgetfulness. Elevated depressive symptoms significantly increased during the COVID-19 lockdown and was associated with food insecurity and reduced ART adherence. Mechanisms for identifying and treating depression and food insecurity are needed to help PLHIV cope with and mitigate the harmful effects of unexpected crises that may impede disease management and access to food.

Project description:Understanding factors related to suboptimal adherence to antiretroviral therapy (ART) and detectable viral load (VL), especially among vulnerable populations, is needed to improve HIV outcomes. The Caribbean is highly impacted by HIV and socioeconomic inequalities, but few studies have been conducted there to explore food insecurity among people with HIV and factors associated with viral suppression in this vulnerable population. Using baseline data from a pilot intervention trial among people living with HIV and food insecurity in the Dominican Republic, we examined psychosocial and behavioral factors associated with viral suppression, ART adherence, and competing needs. Among participants (n = 115), 61% had a detectable VL; the strongest factor associated with detectable VL was having missed taking ART in the last six months due to not having food (OR = 2.68, p = 0.02). Greater odds of reporting missed ART doses due to not having food were associated with severe food insecurity (OR = 4.60, p = 0.006), clinical depression (OR = 2.76, p = 0.018), Haitian background (OR = 6.62 p = 0.017), and internalized HIV stigma (OR = 1.09, p = 0.041), while lower odds were associated with social support (OR = 0.89, p = 0.03) and having health insurance (OR = 0.27, p = 0.017). Ensuring that people with HIV and food insecurity have food to take with their ART is essential for viral suppression.

Project description: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.

Project description:IntroductionTo develop a patient-centred financial incentive delivery strategy to improve antiretroviral treatment adherence in adolescents and young adults (AYA) living with HIV in Kisumu, Kenya, we conducted a mixed methods study exploring preferences.MethodsA discrete choice experiment (DCE) and focus group discussion (FGD) were conducted simultaneously to identify preferences for five incentive delivery strategy features: value, eligibility, recipient, format and disbursement frequency. We used consecutive sampling to recruit AYA (14-24 years) living with HIV attending three health facilities in Kisumu, Kenya. We calculated mean preferences, willingness to trade, latent class membership and predictors of latent class membership. The FGD explored preferred incentive features, and, after deductive and inductive coding, qualitative findings were triangulated with DCE results.ResultsTwo hundred and seven AYA living with HIV (46% 14-17 years, 54% 18-24 years; 33% male sex, 89% viral load <50 copies/ml) were recruited to the study (28 October-16 November 2020). Two distinct preference phenotypes emerged from the DCE analysis (N = 199), 44.8% of the population fell into an "immediate reward" group, who wanted higher value cash or mobile money distributed at each clinic visit, and 55.2% fell into a "moderate spender" group, who were willing to accept lower value incentives in the form of cash or shopping vouchers, and accrued payments. The immediate reward group were willing to trade up to 200 Kenyan Shillings (KSH)-approximately 2 US dollars (USD)-of their 500 KSH (∼5 USD) incentive to get monthly as opposed to accrued yearly payments. The strongest predictor of latent class membership was age (RR 1.45; 95% CI: 1.08-1.95; p = 0.006). Qualitative data highlighted the unique needs of those attending boarding school and confirmed an overwhelming preference for cash incentives which appeared to provide the greatest versatility for use.ConclusionsProviding small financial incentives as cash was well-aligned with AYA preferences in this setting. AYA should additionally be offered a choice of other incentive delivery features (such as mobile money, recipient and disbursement frequency) to optimally align with the specific needs of their age group and life stage.

Project description:BackgroundHousehold food insecurity has been associated with pregnancy complications and poorer birth outcomes in the United States and with maternal mental disorders in the United Kingdom, but there has been little investigation of the effects of food insecurity during this life stage in Canada.ObjectivesOur objective was to examine the relationship between the food insecurity status of women during pregnancy and maternal and birth outcomes and health in infancy in Canada.MethodsWe drew on data from 1998 women in Ontario, Canada, whose food insecurity was assessed using the Household Food Security Survey Module on the Canadian Community Health Survey, cycles 2005 to 2011-2012. These records were linked to multiple health administrative databases to identify indications of adverse health outcomes during pregnancy, at birth, and during children's first year of life. We included women who gave birth between 9 months prior and 6 months after their interview date, and for whom infant outcome data were available. Multivariable Poisson regression models were used to compare outcomes by maternal food security status, expressed as adjusted relative risks (aRR) with 95% CIs.ResultsWhile pregnant, 5.6% of women were marginally food insecure and 10.0% were moderately or severely food insecure. Food insecurity was unrelated to pregnancy complications and adverse birth outcomes, but 26.8% of women with moderate or severe food insecurity had treatment for postpartum mental disorders in the 6-month postpartum period, compared to 13.9% of food-secure women (aRR, 1.86; 95% CI, 1.40-2.46). Children born to food-insecure mothers were at elevated risk of being treated in an emergency department in the first year of life (aRR, 1.18; 95% CI, 1.01-1.38).ConclusionsMaternal food insecurity during pregnancy in Ontario, Canada, is associated with postpartum mental disorders and a greater likelihood of infants being treated in an emergency department.
