RESUMO

With improved survival, adults living with HIV (ALHIV) are increasingly likely to experience age-related and HIV-related comorbidities, including renal insufficiency. Other risk factors for renal insufficiency (high blood pressure (BP), obesity, diabetes, and dyslipidemia) are also growing more common among ALHIV. To determine the prevalence of renal insufficiency (defined as an eGFR < 60 mL/min/1.73 m2) and factors associated with reduced eGFR, we conducted a cross-sectional study at six HIV clinics in Dar-es-Salaam, Tanzania. We applied multivariable (MV) ordinal logistic regression models to identify factors associated with reduced eGFR and examined the interaction of age with BP levels. Among the 450 ALHIV on ART analyzed [26% males; median age 43 (IQR: 18-72) years; 89% on tenofovir-containing ART; 88% HIV viral load ≤50 copies/mL], 34 (7.5%) had renal insufficiency. Prevalence was higher among males (12%) vs. females (6%), p = 0.03; ALHIV ≥50 (21%) vs. <50 years (2.5%), p < 0.001; those with high [≥130/80 mmHg (15%)] vs. normal [<120/80 mmHg (4%)] BP, p < 0.01 and those with dyslipidemia (10%) vs. those without (4.5%), p < 0.03. After adjusting for covariates, age (in years) was the only covariate with a statistically significant association with reduced eGFR (OR = 1.09 (1.07-1.12), p < 0.001). No significant interaction between age and BP was found. Interventions to increase routine screening for renal insufficiency, especially among older ALHIV, and improve BP control are critical to reducing kidney disease-related morbidity and mortality.

RESUMO

BACKGROUND: For adults living with HIV (ALHIV) and comorbidities, access to comprehensive healthcare services is crucial to achieving optimal health outcomes. This study aims to describe lived experiences, challenges, and coping strategies for accessing care for hypertension and/or diabetes (HTN/DM) in HIV care and treatment clinics (CTCs) and other healthcare settings. METHODOLOGY: We conducted a qualitative study that employed a phenomenological approach between January and April 2022 using a semi-structured interview guide in six HIV CTCs in Dar es Salaam, Tanzania. We purposively recruited 33 ALHIV with HTN (n = 16), DM (n = 10), and both (n = 7). Thematic content analysis was guided by the 5As framework of access to care. FINDINGS: The majority of the participants were females, between the ages of 54-73, and were recruited from regional referral hospitals. HIV CTCs at regional referral hospitals had more consistent provision of HTN screening services compared to those from district hospitals and health centers. Participants sought HTN/DM care at non-CTC health facilities due to the limited availability of such services at HIV CTCs. However, healthcare delivery for these conditions was perceived as unaccommodating and poorly coordinated. The need to attend multiple clinic appointments for the management of HTN/DM in addition to HIV care was perceived as frustrating, time-consuming, and financially burdensome. High costs of care and transportation, limited understanding of comorbidities, and the perceived complexity of HTN/DM care contributed to HTN/DM treatment discontinuity. As a means of coping, participants frequently monitored their own HTN/DM symptoms at home and utilized community pharmacies and dispensaries near their residences to check blood pressure and sugar levels and obtain medications. Participants expressed a preference for non-pharmaceutical approaches to comorbidity management such as lifestyle modification (preferred by young participants) and herbal therapies (preferred by older participants) because of concerns about side effects and perceived ineffectiveness of HTN/DM medications. Participants also preferred integrated care and focused patient education on multimorbidity management at HIV CTCs. CONCLUSION: Our findings highlight significant barriers to accessing HTN/DM care among ALHIV, mostly related to affordability, availability, and accessibility. Integration of NCD care into HIV CTCs, could greatly improve ALHIV health access and outcomes and align with patient preference.

RESUMO

The COVID-19 pandemic and associated prevention strategies caused widespread interruptions to care and treatment for people living with HIV. Adolescents living with HIV (AWHIV) were particularly vulnerable to poor mental and physical health during COVID-19. We assessed the burden of generalized and COVID-19-related anxiety and associations with adherence to HIV care and treatment and viral load suppression (VLS) among AWHIV during the peak of the COVID-19 pandemic in Tanzania. Methods: This cross-sectional study was conducted among AWHIV aged 15-19 years attending 10 clinics in Dar es Salaam from April 2022-February 2023. Study participants completed a self-administered questionnaire including Generalized Anxiety Disorder (GAD), COVID-19-related anxiety, and other psychosocial and physical health and support measures. HIV visit adherence, viral load and sociodemographic data were abstracted from patient health records.Analysis:: Multivariable (MV) quasibinomial and logistic regression models examined associations of Generalized and COVID-19-related anxiety with visit adherence and HIV virologic suppression (HIV VL < 50 copies/mL). Data were analyzed using R software. Results: 658 AWHIV (52% male) were included in this analysis. Most (86%) had been on antiretroviral treatment (ART) for at least four years, 55% attended at least 75% of their scheduled clinic visits, and 78% were HIV virologically suppressed. The median GAD and COVID-19-related anxiety scores were 2 (IQR: 0-5, and 26 (IQR: 13-43; respectively. Only 2% scored moderate-severe generalized anxiety (score 10-21). We found no significant associations between COVID-19-related anxiety or GAD and visit adherence. Higher GAD was inversely associated with VLS (adjusted odds ratio (AOR): 0.89 (95% CI 0.81, 0.98)). Female gender and higher quality of physical life were significantly associated with VLS. Conclusion: Low levels of generalized and COVID-19 related anxiety were reported among Tanzanian AWHIV. Integrating screening and management of generalized anxiety screening into HIV care for AWHIV could improve VLS among this population.

RESUMO

PURPOSE: We evaluate contraceptive use and pregnancy two years following an intervention in Tanzania, which provided antenatal post-partum family planning counselling and post-partum intrauterine device (PPIUD) services following delivery. METHODS: We analyse data from five hospitals in Tanzania using a difference-in-difference cluster randomised design, with randomisation at the hospital level. We use women-level data collected at the index birth and a follow-up survey two years later among 6,410 women. Outcomes (overall modern contraceptive use, contraceptive type, pregnancy) are modelled with an intent-to-treat (ITT) approach using linear regression. We compare with the complier average causal effect (CACE) of the intervention among those counselled. RESULTS: The intervention increased long-term PPIUD use by 5.8 percentage points (95% CI: 0.7-11.2%) through substitution away from other modern methods. There was no impact on overall modern contraceptive prevalence or pregnancy. Only 29% of women reported receiving PPIUD counselling. When accounting for this in the CACE analysis we saw a larger impact with 25.7% percentage point increase in PPIUD use (95% CI: 22.7-28.6%). CONCLUSION: The intervention provided women an additional contraceptive choice, resulting in higher use of PPIUD over two years. Increase in PPIUD use was brought about by shifting methods, not creating new modern contraceptive users.


The post-partum family planning intervention in Tanzania offered women a new contraceptive option and increased sustained use of post-partum IUD. The intervention did not attract new modern contraception users and could have a greater impact if implemented more widely.

RESUMO

The provision of high-quality antenatal care (ANC) is important for preventing maternal and newborn mortality and morbidity, but only around half of pregnant women in Tanzania attended four or more ANC visits in 2019. Although there is emerging evidence on the benefit of community health worker (CHW) interventions on ANC uptake, few large-scale pragmatic trials have been conducted. This pragmatic cluster-randomized trial, implemented directly through the public sector health system, assessed the impact of an intervention that trained public sector CHWs to promote the uptake of ANC. We randomized 60 administrative wards in Dar es Salaam to either a targeted CHW intervention or a standard of care. The impact of the intervention was assessed using generalized estimating equations with an independent working correlation matrix to account for clustering within wards. A total of 243 908 women were included in the analysis of our primary outcome of four or more ANC visits. The intervention significantly increased the likelihood of attending four or more ANC visits [relative risk (RR): 1.42; 95% confidence interval (CI): 1.05, 1.92] and had a modest beneficial effect on the total number of ANC visits (percent change: 7.7%; 95% CI: 0.2%, 15.5%). While slightly more women in the intervention arm attended ANC in their first trimester compared with the standard-of-care arm (19% vs 18.7%), the difference was not significant (RR: 1.02; 95% CI: 0.84, 1.22). Our findings suggest that trained CHWs can increase attendance of ANC visits in Dar es Salaam and similar settings. However, additional interventions appear necessary to promote the early initiation of ANC. This study demonstrates that routine health system data can be leveraged for outcome assessment in trials and programme evaluation and that the results are likely superior, both in terms of bias and precision, to data that are collected specifically for science.

RESUMO

BACKGROUND: The UNAIDS estimate of vertical HIV transmission in Tanzania is high (11%), despite 84% uptake of antiretroviral therapy (ART) among pregnant women with HIV. We aimed to evaluate vertical transmission and its determinants by 18 months post partum among women on lifelong ART in routine health-care settings in Tanzania. METHODS: We conducted a prospective cohort study in 226 health facitilies across Dar-es-Salaam, Tanzania. Eligible participants were pregnant women of any age with HIV, and later their infants, who enrolled in routine health-care services for the prevention of vertical transmission. We prospectively followed up mother-infant pairs at routine monthly visits until 18 months post partum and extracted data from the care and treatment clinic (CTC2) database, a national electronic database that stores patient-level HIV care and treatment clinic data. The primary outcome was time from birth to HIV diagnosis, defined as a positive infant HIV DNA PCR or antibody test from age 18 months. We used the Kaplan-Meier method to estimate cumulative risk of vertical transmission by 18 months post partum and Cox proportional hazards regression with shared frailties to account for potential clustering in health facilities to evaluate predictors of transmission. FINDINGS: Between Jan 1, 2015, and Dec 31, 2017, 22 930 pregnant women with HIV (median age 30 years, IQR 25-34) enrolled on a care programme. After excluding 9140 (39·9%) women and 539 (2·4%) infants with missing outcome data, 13 251 (59·0%) mother-infant pairs were analysed, of whom 6072 (45·8%) women were already on ART before pregnancy. By 18 months post partum, 159 (1·2%) of 13 251 infants were diagnosed with HIV, equivalent to a risk of vertical transmission of 1·4% (95% CI 1·2-1·6). In the complete case analysis, the rates of vertical transmission were higher among women who enrolled in the third trimester of pregnancy than among those who enrolled in the first trimester (adjusted hazard ratio 3·01, 95% CI 1·59-5·70; p=0·0003), among women with advanced HIV disease than among those with early-stage disease (1·89, 1·22-2·93; p=0·0046), and among women who were on a second-line ART regimen than among those on a first-line regimen (3·58, 1·08-11·82; p=0·037). By contrast, the rate of vertical transmission was lower among women who were already on ART at enrolment than among those starting ART at enrolment (0·39, 0·25-0·60; p<0·0001) as well as among women in high-volume clinics than among those in low-volume clinics (0·46 (0·24-0·90; p<0·0097). INTERPRETATION: Provision of ART for life (WHO's option B+ recommendation) has reduced the risk of vertical transmission to less than 2% among pregnant women with HIV in routine care settings in urban Tanzania. There is still a need to improve timely HIV diagnosis and ART uptake, and to optimise follow-up for the prevention of vertical transmission and the uptake of infant HIV testing.

RESUMO

BACKGROUND: Perinatal women living with HIV (PWLH) have a greater risk of depression compared to other women; however, there are limited specialized mental health services available to them. We aimed to determine whether a stepped-care intervention facilitated by trained lay providers can improve mental health outcomes postpartum for PWLH. METHODS AND FINDINGS: Healthy Options is a cluster-randomized controlled study conducted in 16 government-managed antenatal care clinics that provided HIV care for pregnant women in urban Tanzania. Recruitment occurred from May 2015 through April 2016, with the final round of data collection completed in October 2017. Participants included a consecutive sample of pregnant women under 30 weeks of gestation, living with HIV and depression, and attending the study clinics. Control sites received enhanced usual care for depression (EUDC). Intervention sites received EUDC plus the Healthy Options intervention, which includes prenatal group sessions of problem-solving therapy (PST) plus cognitive behavioral therapy (CBT) sessions for individuals showing depressive symptoms at 6 weeks postdelivery. We assessed depressive symptoms comparable to major depressive disorder (MDD) using the Patient Health Questionnaire-9 (PHQ-9) with a locally validated cutoff at 9 months and 6 weeks postpartum. The primary time point is 9 months postpartum. We examined differences in outcomes using an intent-to-treat analysis with a complete case approach, meaning those with data at the relevant time point were included in the analysis. We used generalized estimating equations accounting for clustering. Of 818 women screened using the PHQ-9, 742 were determined eligible and enrolled (395 intervention; 347 control); 649 women (87.5%) participated in the first follow-up and 641 women (86.4%) in the second. A majority (270, 74.6%) of women in the intervention arm attended 5 or more PST sessions. Women enrolled in Healthy Options demonstrated a 67% (RR 0.33; 95% CI: 0.22, 0.51; p-value: <0.001; corresponding to a 25.7% difference in absolute risk) lower likelihood of depressive symptoms than women in control clusters at 6 weeks postpartum. At 9 months postpartum, women enrolled in Healthy Options demonstrated a nonsignificant 26% (RR 0.74; 95% CI: 0.42, 1.3; p-value: 0.281; corresponding to a 3.2% difference in absolute risk) lower likelihood of depressive symptoms than women in control clusters. Study limitations include not using diagnostic interviews to measure depression and not blinding data collectors to intervention status during follow-up. CONCLUSIONS: The Healthy Options intervention did not demonstrate reduction in depressive symptoms at 9 months postpartum, the primary outcome. Significant reductions were seen in depression symptoms at 6 weeks postpartum, the secondary outcome. Stepped-care interventions may be relevant for improving outcomes in the critical early postpartum window. TRIAL REGISTRATION: Clinical Trial registration number (closed to new participants) NCT02039973.

RESUMO

OBJECTIVE: People living with HIV/AIDS (PLHA) are experiencing growing co-morbidities due to an increase in life expectancy and the use of long-term antiretroviral therapy (ART). The lack of integrated non-communicable diseases (NCDs) screening and management at the HIV care and treatment centres (CTCs) make it difficult to determine the trends of NCD co-morbidity among patients with HIV. This study aimed to assess the burden and determinants of common NCDs, including depression among patients with HIV. METHODS: Analytical cross-sectional study of 1318 HIV patients enrolled using systematic random sampling conducted from April to November 2020. Five large CTCs in district referral hospitals were selected representing the five districts of Dar es Salaam including Mwananyamala, Temeke, and Amana regional referral hospitals and Sinza and Vijibweni hospitals. The study population consisted of adult PLHA aged 18 years and above. The primary outcome measure was the prevalence of NCDs among HIV patients. Observation of actual NCD medications or their purchase receipts or booked NCD clinic appointments that PLHA had during the study period was used to verify the reported presence of NCDs. The secondary outcome measure was the prevalence of probable depression among PLHA. The locally validated Swahili Patient Health Questionnaire (PHQ-9) was used to screen for depressive symptom severity. A logistic regression model was used to identify factors associated with common NCDs and those associated with probable depression. Potential risk factors that were statistically significant at a P-value of 0.2 or less in univariable analysis were included as potential confounders in multivariable models. RESULTS: The median age of participants was 42 (IQR 35-49) years, with 32.7% in the 36-45 years age group. The majority of patients were women (69%). Most (80.5%) had achieved HIV viral (VL) suppression (a serum HIV VL of <1000 copies/ml). Overall, 14.3% of self-reported an NCD with evidence of their current medication for the NCD from receipts for medication purchased and appointments from NCD clinics they attended. In the multivariable analyses, higher odds of NCDs were in older patients (>45 years) and those with a weight above 75 kg (P < 0.05). Male patients had 51% reduced odds of NCDs (aOR 0.49; 95% CI: 0.32-0.74) than females (P < 0.001). Probable depression prevalence was 11.8%, and depressed patients had more than twice the odds of having NCDs than those without depression (aOR 2.26; 95% CI: 1.45-3.51; P < 0.001). CONCLUSION: This study determined co-existing previously diagnosed NCDs among PLHA accessing care and high levels of depressive symptom severity. We recommend additional research on the feasibility, acceptability, and cost implications of screening and treating NCDs on HIV care platforms to provide evidence for Tanzania's integrated HIV/NCD care model.

RESUMO

HIV-related stigma represents a potent risk factor for a range of poor health outcomes, including mental health symptoms, treatment non-adherence, and substance use. Understanding the role of HIV-related stigma in promoting healthcare outcomes is critical for vulnerable populations, such as pregnant women living with HIV, in contexts with continued high rates of HIV and associated stigma, such as sub-Saharan Africa. The current study examined a range of risk and protective factors for HIV-related stigma with 742 pregnant women (M age = 29.6 years) living with depression and HIV accessing prevention of mother-to-child transmission of HIV (PMTCT) services in Dar es Salaam, Tanzania. Risk factors included depressive symptoms, ART non-adherence, intimate partner violence, food insecurity, and alcohol problems. Protective factors included disclosure of HIV status, social support, an appreciative relationship with their partner, hope, and self-efficacy. Findings highlight key psychosocial and behavioral determinants of HIV-related stigma for pregnant women living with HIV in Tanzania, and can inform perinatal care programming and interventions to optimize mental health and adherence outcomes.

RESUMO

BACKGROUND: Global mortality attributable to non-communicable diseases (NCDs) occurs in more than 36 million people annually with 80% of these deaths occurring in resource limited countries. Among people living with HIV and AIDS (PLHA) studies have reported higher prevalence's of NCDs compared to the general population but most studies do report a narrow range of NCDs commonly hypertension, diabetes and neoplasms and not all. In addition, there is limited reporting, integration of systematic screening and treatment for all NCDs among PLHA attending care, suggesting the NCD burden among PLHA is likely an underestimate. Little is known about factors facilitating or hindering integration of the care and treatment of NCDs within HIV care and treatment clinics (CTCs) in Tanzania. OBJECTIVE: To explore the perceptions of PLHA and health workers on factors facilitate or hinder the recognition and integration of care for NCDs within CTCs in Dar es Salaam. METHODS: Inductive content analysis of transcripts from 41 in-depth interviews were conducted with 5 CTC managers (CTC Managers), 9 healthcare providers (DHCP) and 27 people living with HIV (PLHA) attending CTCs and with co-morbid NCDs. RESULTS: Four themes emerged; the current situation of services available for care and treatment of NCDs among PLHA in CTCs, experiences of PLHA with co-morbid NCDs with access to care and treatment services for NCDs, facilitators of integrating care and treatment of NCDs within CTCs and perceived barriers for accessing and integration of care and treatment of NCDs within CTCs. CONCLUSIONS: There was a positive attitude among PLHA and healthcare workers towards integration of NCD services within CTC services. This was enhanced by perceived benefits inherent to the services. Factors hindering integration of NCD care and services included; limited and inconsistent supplies such as screening equipment, medications; insufficient awareness of NCDs within PLHA; lack of adequate training of healthcare workers on management of NCD and treatment costs and payment systems.

RESUMO

The NAMWEZA intervention was implemented, using a ten-session group format, to build skills targeting psychosocial vulnerabilities and enhancing HIV prevention among people living with HIV (PLH) and their social networks. The overall goal of this intervention is to improve psychological wellbeing and reduce HIV risk behaviours. These analyses aim to describe the barriers and facilitators of implementing the NAMWEZA intervention from the perspective of participants and trained peer group facilitators. Twenty-four in-depth interviews were conducted with NAMWEZA participants, and 50 pooled peer facilitator self-assessment reports were obtained from 16 trained peers. Participants identified personal and structural barriers, including fear of inadvertent HIV status disclosure, time constraints, level of participant reimbursements, and limited space available for group sessions. Factors facilitating effective implementation included perceived benefits of the program, such as reduction in HIV-related risk behaviours, increased self-esteem, and improvement in confidence in HIV prevention communications. Scaling up the NAMWEZA intervention to other areas of Tanzania or regionally should take into account these facilitators and barriers to implementation.

RESUMO

Intimate partner violence (IPV) exacts a heavy burden on women, resulting in poor health outcomes. This study had the following aims: (1) estimate the prevalence of IPV post-disclosure of HIV status among pregnant women living with HIV and depression; and (2) evaluate risk and protective factors for IPV post-disclosure. Participants were women accessing PMTCT services at 16 health facilities in Dar es Salaam and screened at the threshold of 9 on the PHQ-9. Generalized linear equations with a log link and standard errors clustered at the facility level were used to calculate associations between predictors and IPV post-disclosure. Among 659 women who were in an intimate relationship, 10.2% had experienced physical violence and 11.6% had reported sexual violence from their partner in the past six months; 327 had disclosed their HIV status to their partners. After disclosure to their partners 279 women (85.3%) experienced IPV. HIV-related stigma was associated with increased risk of IPV following disclosure and appreciative relationships with partners and higher hope were associated with reduced risk of IPV. There is a need to identify and advance approaches to HIV disclosure that prevent IPV. Interventions should be developed based on known risk and protective factors for IPV following HIV disclosure in Tanzania and similar settings.

RESUMO

The aim of the study is to compare sociodemographic characteristics, psychosocial factors, HIV knowledge and risk behaviors of people living with HIV (PLH) and their social network members (NMs) to inform HIV prevention programs that engage PLH as prevention educators in their communities. We compared baseline characteristics of PLH enrolled in an intervention to become HIV prevention Change Agents (CAs) (n = 458) and 602 NMs they recruited. CAs and NMs responded to questionnaires through a computer-driven interface with Audio Computer-Assisted Self Interview (ACASI) software. Although NMs scored higher on socio-economic status, self-esteem and general self-efficacy, they had lower HIV knowledge (AOR 1.5; 95% CI: 1.1-2.1), greater inconsistent condom use (AOR 3.2; 95% CI: 2.4-4.9), and recent experience as perpetrators of physical (AOR 2.5; 95% CI: 1.2-5.1) or sexual (AOR 4.1; 95% CI: 1.4-12.7) intimate partner violence; and as victims of physical (AOR 1.5; 95% CI: 1.0-2.3) or sexual (AOR 2.2; 95% CI: 1.3-3.8) forms of violence than CAs. Higher HIV knowledge and lower sexual risk behaviors among CAs suggest PLH's potential as communicators of HIV prevention information to NMs. CAs' training should also focus on improving self-esteem, general self-efficacy and social support to increase their potential effectiveness as HIV prevention educators and enhance their own overall health and well-being.

RESUMO

BACKGROUND: This qualitative study assessed implementation of the Postpartum Intrauterine Device (PPIUD) Initiative in Tanzania, a country with high rates of unintended pregnancy and low contraceptive prevalence. The PPIUD Initiative was implemented to reduce unmet need for contraception among new mothers through postpartum family planning counseling delivered during antenatal care and offering PPIUD insertion immediately following birth. METHODS: We used the implementation outcomes framework and an ecological framework to analyze in-depth interviews with providers (N=15) and women (N=47) participating in the initiative. We applied a multistage coding protocol and used thematic content analysis to identify the factors influencing implementation. RESULTS: Both women and providers were enthusiastic and receptive to the PPIUD Initiative. Health system and resource constraints made adoption and fidelity to the intended intervention challenging. Many providers questioned the sustainability of the initiative, and most agreed that changes to the initiative's design (e.g., additional training opportunities, improved staffing, and availability of PPIUD supplies) would strengthen future iterations of the initiative. According to women, interpersonal aspects of care varied, with some women reporting rushed or incomplete counseling or an emphasis on the PPIUD over other methods. The perception that some providers treat older married women more favorably suggests that fidelity to the intended PPIUD Initiative was not uniformly achieved. CONCLUSIONS: Study findings inform initiatives seeking to develop and adopt postpartum family planning programs and enhance program implementation. A comprehensive needs assessment to evaluate feasibility and identify potential adaptations for the local context is recommended. Training and supervision to improve interpersonal aspects of care, including an emphasis on patient-centered counseling, informed choice, and respectful and nondiscriminatory service delivery should be integrated into future postpartum family planning initiatives.

RESUMO

BACKGROUND: Hope or hopefulness enhances coping and improves quality of life in persons with chronic or incurable illnesses. Lack of hope is associated with depression and anxiety, which impact negatively on quality of life. In Tanzania, where HIV prevalence is high, the rates of depression and anxiety are over four times higher among people living with HIV (PLH) compared to persons not infected and contribute annual mortality among PLH. Tanzania has a shortage of human resources for mental health, limiting access to mental health care. Evidence-based psychosocial interventions can complement existing services and improve access to quality mental health services in the midst of human resource shortages. Facilitating hope can be a critical element of non-pharmacological interventions which are underutilized, partly due to limited awareness and lack of hope measures, adapted to accommodate cultural context and perspectives of PLH. To address this gap, we developed and validated a local hope measure among PLH in Tanzania. METHODS: Two-phased mixed methods exploratory sequential study among PLH. Phase I was Hope-related items identification using deductive, inductive approaches and piloting. Phase II was an evaluation of psychometric properties at baseline and 24 months. Classical test theory, exploratory, confirmatory factor analysis (CFA) were used. RESULTS: Among 722 PLH, 59% were women, mean age was 39.3 years, and majority had primary school level of education. A total of 40 hope items were reduced to 10 in a three-factor solution, explaining 69% of variance at baseline, and 93% at follow-up. Internal consistency Cronbach's alpha was 0.869 at baseline and 0.958 at follow-up. The three-factor solution depicted: positive affect; cognition of effectiveness of HIV care; and goals/plans/ future optimism. Test-retest reliability was good (r = 0.797) and a number of indices were positive for CFA model fit, including Comparative Fit Index of 0.984. CONCLUSION: The developed local hope scale had good internal reliability, validity, and its dimensionality was confirmed against expectations. The fewer items for hope assessment argue well for its use in busy clinical settings to improve HIV care in Tanzania. Hope in this setting could be more than cognitive goal thinking, pathway and motivation warranting more research. TRIAL REGISTRATION: The intervention was registered in USA ClinicalTrials.gov on September 26, 2012, Registration number: NCT01693458.

RESUMO

BACKGROUND: Perinatal women accessing prevention of mother-to-child transmission of HIV (PMTCT) services are at an increased risk of depression; however, in Tanzania there is limited access to services provided by mental health professionals. This paper presents a protocol and baseline characteristics for a study evaluating a psychosocial support group intervention facilitated by lay community-based health workers (CBHWs) for perinatal women living with HIV and depression in Dar es Salaam. METHODS: A cluster randomized controlled trial (RCT) is conducted comparing: 1) a psychosocial support group intervention; and 2) improved standard of mental health care. The study is implemented in reproductive and child health (RCH) centers providing PMTCT services. Baseline characteristics are presented by comparing sociodemographic characteristics and primary as well as secondary outcomes for the trial for intervention and control groups. The trial is registered under clinicaltrials.gov (NCT02039973). RESULTS: Among 742 women enrolled, baseline characteristics were comparable for intervention and control groups, although more women in the control group had completed secondary school (25.2% versus 18.2%). Overall, findings suggest that the population is highly vulnerable with over 45% demonstrating food insecurity and 17% reporting intimate partner violence in the past 6 months. CONCLUSIONS: Baseline characteristics for the cluster RCT were comparable for intervention and control groups. The trial will examine the effectiveness of a psychosocial support group intervention for the treatment of depression among women living with HIV accessing PMTCT services. A reduction in the burden of depression in this vulnerable population has implications in the short-term for improved HIV-related outcomes and for potential long-term effects on child growth and development. TRIAL REGISTRATION: The trial is registered under clinicaltrials.gov (NCT02039973). Retrospectively registered on January 20, 2014.

RESUMO

Despite the numerous benefits of the postpartum copper intrauterine device (PPIUD), which is inserted within 48 hours after giving birth, it is underutilized in many resource-constrained settings, including Tanzania. We conducted in-depth interviews with 20 pregnant women who received contraceptive counseling during routine antenatal care in 2016-2017 and 27 postpartum women who had a PPIUD inserted in 2018 to understand reasons for use versus nonuse and continuation versus discontinuation. Primary motivators for using a PPIUD included: convenience, effectiveness, perceived lack of side effects, and duration of pregnancy protection. Barriers to use included: fear of insertion, concerns related to sexual experiences post-insertion, and limited knowledge. Women who had a PPIUD inserted continued use when their expectations matched their experience, while discontinuation resulted from unexpected expulsion and experience of unanticipated side effects. Frequent follow-up and guidance on side-effect management influenced women's decisions to continue use. To support uptake and continued utilization of the PPIUD, postpartum contraceptive counseling should explicitly address side effects and risk of expulsion.

RESUMO

Although a number of HIV prevention programs have been implemented, such as mass media campaigns, high rates of unprotected and concurrent sexual partnerships, as well as low uptake HIV testing and limited HIV knowledge, persist in Tanzania. We examined the effect and predicting factors of HIV prevention communication among people living with HIV (PLH) exposed to NAMWEZA intervention, and their at-risk social network members (NMs) Quantitative data were collected from 326 participants at baseline and 24 months of follow-up. In-depth interviews with 20 PLH were conducted at follow-up. Results indicated specific communication about condom use and HIV testing increased; (mean increase of 0.28 (SD = 0.14) scores, P = 0.012 and 0.42 (SD = 0.11) scores, p < 0.001 respectively while general discussion about protecting other people from HIV did not change significantly; mean increase was 0.01 scores (SD = 0.005), p = 0.890. Positive predictors of communication included being single; OR = 1.10, p = 0.01, female; OR = 1.15, p = 0.03, aged 30 years or older; OR = 1.23, p < 0.01, HIV knowledge, dose of NAMWEZA participation; OR = 1.01, p < 0.001, and high self-efficacy for condom use; OR = 1.4, p < 0.001. Stigma demonstrated a significant but negative association with communication for condom use; OR = 1.01, p < 0.01.Qualitative data reflected perceived possession of more individual skills and ability to address some personal/cultural obstacles to communicating about HIV prevention including those observed in the quantitative data. NAMWEZA improved communication about HIV prevention among PLH with their at-risk-NMs. The approach is a promising complement to media campaigns in similar populations. Future research and program evaluation efforts should explore how communities perceive and communicate about protecting others from HIV.

RESUMO

INTRODUCTION: NAMWEZA is a novel intervention that focuses on preventing HIV and promoting sexual and reproductive health and rights by addressing underlying factors related to vulnerability of acquiring HIV, such as depression, intimate partner violence (IPV) and stigma. The goal of the study was to evaluate the effect of the NAMWEZA intervention on risk behaviour as well as factors potentially contributing to this vulnerability for people living with HIV and their network members. METHODS: A stepped-wedge randomised controlled trial was conducted from November 2010 to January 2014 among people living with HIV and their network members in Dar es Salaam, Tanzania. 458 people living with HIV were randomised within age/sex-specific strata to participate in the NAMWEZA intervention at three points in time. In addition, 602 members of their social networks completed the baseline interview. Intention-to-treat analysis was performed, including primary outcomes of uptake of HIV services, self-efficacy, self-esteem, HIV risk behaviour and IPV. RESULTS: For people living with HIV, a number of outcomes improved with the NAMWEZA intervention, including higher self-efficacy and related factors, as well as lower levels of depression and stigma. IPV reduced by 40% among women. Although reductions in HIV risk behaviour were not observed, an increase in access to HIV treatment was reported for network members (72% vs 94%, p=0.002). CONCLUSION: These results demonstrate the complexity of behavioural interventions in reducing the vulnerability of acquiring HIV, since it is possible to observe a broad range of different outcomes. This study indicates the importance of formally evaluating interventions so that policymakers can build on evidence-based approaches to advance the effectiveness of HIV prevention interventions. TRIAL REGISTRATION NUMBER: NCT01693458.

RESUMO

BACKGROUND: Home delivery and late and infrequent attendance at antenatal care (ANC) are responsible for substantial avoidable maternal and pediatric morbidity and mortality in sub-Saharan Africa. This cluster-randomized trial aimed to determine the impact of a community health worker (CHW) intervention on the proportion of women who (i) visit ANC fewer than 4 times during their pregnancy and (ii) deliver at home. METHODS AND FINDINGS: As part of a 2-by-2 factorial design, we conducted a cluster-randomized trial of a home-based CHW intervention in 2 of 3 districts of Dar es Salaam from 18 June 2012 to 15 January 2014. Thirty-six wards (geographical areas) in the 2 districts were randomized to the CHW intervention, and 24 wards to the standard of care. In the standard-of-care arm, CHWs visited women enrolled in prevention of mother-to-child HIV transmission (PMTCT) care and provided information and counseling. The intervention arm included additional CHW supervision and the following additional CHW tasks, which were targeted at all pregnant women regardless of HIV status: (i) conducting home visits to identify pregnant women and refer them to ANC, (ii) counseling pregnant women on maternal health, and (iii) providing home visits to women who missed an ANC or PMTCT appointment. The primary endpoints of this trial were the proportion of pregnant women (i) not making at least 4 ANC visits and (ii) delivering at home. The outcomes were assessed through a population-based household survey at the end of the trial period. We did not collect data on adverse events. A random sample of 2,329 pregnant women and new mothers living in the study area were interviewed during home visits. At the time of the survey, the mean age of participants was 27.3 years, and 34.5% (804/2,329) were pregnant. The proportion of women who reported having attended fewer than 4 ANC visits did not differ significantly between the intervention and standard-of-care arms (59.1% versus 60.7%, respectively; risk ratio [RR]: 0.97; 95% CI: 0.82-1.15; p = 0.754). Similarly, the proportion reporting that they had attended ANC in the first trimester did not differ significantly between study arms. However, women in intervention wards were significantly less likely to report having delivered at home (3.9% versus 7.3%; RR: 0.54; 95% CI: 0.30-0.95; p = 0.034). Mixed-methods analyses of additional data collected as part of this trial suggest that an important reason for the lack of effect on ANC outcomes was the perceived high economic burden and inconvenience of attending ANC. The main limitations of this trial were that (i) the outcomes were ascertained through self-report, (ii) the study was stopped 4 months early due to a change in the standard of care in the other trial that was part of the 2-by-2 factorial design, and (iii) the sample size of the household survey was not prespecified. CONCLUSIONS: A home-based CHW intervention in urban Tanzania significantly reduced the proportion of women who reported having delivered at home, in an area that already has very high uptake of facility-based delivery. The intervention did not affect self-reported ANC attendance. Policy makers should consider piloting, evaluating, and scaling interventions to lessen the economic burden and inconvenience of ANC.
