High rates of undiagnosed and uncontrolled hypertension upon a screening campaign in rural Rwanda: a cross-sectional study.

BACKGROUND: Hypertension remains the major risk factor for cardiovascular diseases (CVDs) worldwide with a prevalence and mortality in low- and middle-income countries (LMICs) among the highest. The early detection of hypertension risk factors is a crucial pillar for CVD prevention. DESIGN AND METHOD: This cross-sectional study included 4284 subjects, mean age 46 ± 16SD, 56.4% females and mean BMI 26.6 ± 3.7 SD. Data were collected through a screening campaign in rural area of Kirehe District, Eastern of Rwanda, with the objective to characterize and examine the prevalence of elevated blood pressure (BP) and other CVD risk factors. An adapted tool from the World Health Organization STEPwise Approach was used for data collection. Elevated BP was defined as ≥ 140/90 mm/Hg and elevated blood glucose as blood glucose ≥ 100 mg/dL after a 6-h fast. RESULTS: Of the sampled population, 21.2% (n = 910) had an elevated BP at screening; BP was elevated among individuals not previously known to have HTN in 18.7% (n = 752). Among individuals with a prior diagnosis of HTN, 62.2% (n = 158 of 254) BP was uncontrolled. Age, weight, smoking, alcohol history and waist circumference were associated with BP in both univariate analyses and multivariate analysis. CONCLUSION: High rates of elevated BP identified through a health screening campaign in this Rwandan district were surprising given the rural characteristics of the district and relatively low population age. These data highlight the need to implement an adequate strategy for the prevention, diagnosis, and control of HTN that includes rural areas of Rwanda as part of a multicomponent strategy for CVD prevention.

The T-Cell Inhibitory Molecule Butyrophilin-Like 2 Is Up-regulated in Mild Plasmodium falciparum Infection and Is Protective During Experimental Cerebral Malaria.

Plasmodium falciparum infection can result in severe disease that is associated with elevated inflammation and vital organ dysfunction; however, malaria-endemic residents gain protection from lethal outcomes and manifest only mild symptoms during infection. To characterize host responses associated with this more effective antimalarial response, we characterized whole-blood transcriptional profiles in Rwandan adults during a mild malaria episode and compared them with findings from a convalescence sample. We observed transcriptional up-regulation in many pathways, including type I interferon, interferon γ, complement activation, and nitric oxide during malaria infection, which provide benchmarks of mild disease physiology. Transcripts encoding negative regulators of T-cell activation, such as programmed death ligand 1 (PD-L1), programmed death 1 ligand 2 (PD-L2), and the butyrophilin family member butyrophilin-like 2 (BTNL2) were also increased. To support an important functional role for BTNL2 during malaria infection, we studied chimeric mice reconstituted with BTNL2(-/-) or wild-type hematopoietic cells that were inoculated with Plasmodium berghei ANKA, a murine model of cerebral malaria. We found that BTNL2(-/-) chimeric mice had a significant decrease in survival compared with wild-type counterparts. Collectively these data characterize the immune responses associated with mild malaria and uncover a novel role for BTNL2 in the host response to malaria.

Effect of deworming on disease progression markers in HIV-1-infected pregnant women on antiretroviral therapy: a longitudinal observational study from Rwanda.

BACKGROUND: Deworming human immunodeficiency virus (HIV)-infected individuals on antiretroviral therapy (ART) may be beneficial, particularly during pregnancy. We determined the efficacy of targeted and nontargeted antihelminth therapy and its effects on Plasmodium falciparum infection status, hemoglobin levels, CD4 counts, and viral load in pregnant, HIV-positive women receiving ART. METHODS: Nine hundred eighty HIV-infected pregnant women receiving ART were examined at 2 visits during pregnancy and 2 postpartum visits within 12 weeks. Women were given antimalarials when malaria-positive whereas albendazole was given in a targeted (n = 467; treatment when helminth stool screening was positive) or nontargeted (n = 513; treatment at all time points, with stool screening) fashion. RESULTS: No significant differences were noted between targeted and nontargeted albendazole treatments for the variables measured at each study visit except for CD4 counts, which were lower (P < .05) in the latter group at the final visit. Albendazole therapy was associated with favorable changes in subjects' hemoglobin levels, CD4 counts, and viral loads, particularly with helminth infections. CONCLUSIONS: Antihelminthic therapy reduces detectable viral load, and increases CD4 counts and hemoglobin levels in pregnant HIV-infected women with helminth coinfections receiving ART.

Sexual Behavior and Risk Practices of HIV Positive and HIV Negative Rwandan Women.

It is not well understood how infection with HIV and prior experience of sexual violence affects sexual behavior in African women. We describe factors influencing current sexual practices of Rwandan women living with or without HIV/AIDS. By design, 75 % of participants were HIV positive and ~50 % reported having experienced genocidal rape. Univariate and multivariate logistic regression models were fit to describe demographic and clinical characteristics that influenced sexual behavior in the previous 6 months, condom use, history of transactional sex, and prior infection with a non-HIV sexually transmitted disease. Respondents' age, where they lived, whether or not they lived with a husband or partner, experience of sexual trauma, CD4 count, CES-D and PTSD scores were strongly associated with risky sexual behavior and infection with non-HIV STI. HIV positive women with a history of sexual violence in the contexts of war and conflict may be susceptible to some high-risk sexual behaviors.

Decentralizing Maternity Services to Increase Skilled Attendance at Birth and Antenatal Care Utilization in Rural Rwanda: A Prospective Cohort Study.

To evaluate the effectiveness of decentralizing ambulatory reproductive and intrapartum services to increase rates of antenatal care (ANC) utilization and skilled attendance at birth (SAB) in Rwanda. A prospective cohort study was implemented with one control and two intervention sites: decentralized ambulatory reproductive healthcare and decentralized intrapartum care. Multivariate logistic regression analysis was performed with primary outcome of lack of SAB and secondary outcome of ≥3 ANC visits. 536 women were entered in the study. Distance lived from delivery site significantly predicted SAB (p = 0.007), however distance lived to ANC site did not predict ≥3 ANC visits (p = 0.81). Neither decentralization of ambulatory reproductive healthcare (p = 0.10) nor intrapartum care (p = 0.40) was significantly associated with SAB. The control site had the greatest percentage of women receive ≥3 ANC visits (p < 0.001). Receiving <3 ANC visits was associated with a 3.98 times greater odds of not having SAB (p = 0.001). No increase in adverse outcomes was found with decentralization of ambulatory reproductive health care or intrapartum care. The factors that predict utilization of physically accessible services in rural Africa are complex. Decentralization of services may be one strategy to increase rates of SAB and ANC utilization, but selection biases may have precluded accurate analysis. Efforts to increase ANC utilization may be a worthwhile investment to increase SAB.

The impact of HIV status, HIV disease progression, and post-traumatic stress symptoms on the health-related quality of life of Rwandan women genocide survivors.

PURPOSE: We examined whether established associations between HIV disease and HIV disease progression on worse health-related quality of life (HQOL) were applicable to women with severe trauma histories, in this case Rwandan women genocide survivors, the majority of whom were HIV-infected. Additionally, this study attempted to clarify whether post-traumatic stress symptoms were uniquely associated with HQOL or confounded with depression. METHODS: The Rwandan Women's Interassociation Study and Assessment was a longitudinal prospective study of HIV-infected and uninfected women. At study entry, 922 women (705 HIV+ and 217 HIV-) completed measures of symptoms of post-traumatic stress and HQOL as well as other demographic, clinical, and behavioral characteristics. RESULTS: Even after controlling for potential confounders and mediators, HIV+ women, in particular those with the lowest CD4 counts, scored significantly worse on HQOL and overall quality of life (QOL) than did HIV- women. Even after controlling for depression and HIV disease progression, women with more post-traumatic stress symptoms scored worse on HQOL and overall QOL than women with fewer post-traumatic stress symptoms. CONCLUSIONS: This study demonstrated that post-traumatic stress symptoms were independently associated with HQOL and overall QOL, independent of depression and other confounders or potential mediators. Future research should examine whether the long-term impact of treatment on physical and psychological symptoms of HIV and post-traumatic stress symptoms would generate improvement in HQOL.

Exploring contextual factors influencing the implementation of evidence-based care for hypertension in Rwanda: a cross-sectional study using the COACH questionnaire.

IMPORTANCE: Hypertension is the largest contributor to the Global Burden of Disease. In Rwanda, as in most low-income and middle-income countries, an increasing prevalence of hypertension and its associated morbidity and mortality is causing major healthcare and economic impact. Understanding healthcare systems context in hypertension care is necessary. OBJECTIVE: To study the hypertension healthcare context as perceived by healthcare providers using the Context Assessment for Community Health (COACH) tool. DESIGN: A cross-sectional cohort responded to the COACH questionnaire and a survey about hypertension training. SETTING: Three tertiary care hospitals in Rwanda. PARTICIPANTS: Healthcare professionals (n=223). PRIMARY OUTCOMES AND MEASURES: The COACH tool consists of 49 items with eight subscales: resources, community engagement, commitment to work, informal payment, leadership, work culture, monitoring services for action (5-point Likert Scale) and sources of knowledge (on a 0-1 scale). Four questions surveyed training on hypertension. RESULTS: Responders (n=223, 75% women; 56% aged 20-35 years) included nurses (n=142, 64%, midwives (n=42, 19%), primary care physicians (n=28, 13%) and physician specialists (n=11, 5%)). The subscales commitment to work, leadership, work culture and informal payment scored between 4.7 and 4.1 and the community engagement, monitoring services for action and organizational resources scored between 3.1 and 3.5. Sources of knowledge had a mean score of 0.6±0.3. While 73% reported having attended a didactic hypertension seminar in the past year, only 28% had received long-term training and 51% had <3-year experience working with hypertension care delivery. The majority (99%) indicated a need for additional training in hypertension care. CONCLUSIONS: There is a need for increased and continuous training in Rwanda. Healthcare responders stated a commitment to work and reported supportive leadership, while acknowledging limited resources and no monitoring systems. The COACH tool provides contextual guidance to develop training strategies prior to the implementation of a sustainable hypertension care programme.

Lipoprotein levels and cardiovascular risk in HIV-infected and uninfected Rwandan women.

BACKGROUND: Lipoprotein profiles in HIV-infected African women have not been well described. We assessed associations of lipoprotein levels and cardiovascular risk with HIV-infection and CD4 count in Rwandan women. METHODS: Cross-sectional study of 824 (218 HIV-negative, 606 HIV+) Rwandan women. Body composition by body impedance analysis, CD4 count, and fasting serum total cholesterol (total-C), triglycerides (TG) and high-density lipoprotein (HDL) levels were measured. Low-density lipoprotein (LDL) was calculated from Friedewald equation if TG < 400 and measured directly if TG ≥ 400 mg/dl. RESULTS: BMI was similar in HIV+ and -negative women, < 1% were diabetic, and HIV+ women were younger. In multivariate models LDL was not associated with HIV-serostatus. HDL was lower in HIV+ women (44 vs. 54 mg/dL, p < 0.0001) with no significant difference by CD4 count (p = 0.13). HIV serostatus (p = 0.005) and among HIV+ women lower CD4 count (p = 0.04) were associated with higher TG. BMI was independently associated with higher LDL (p = 0.01), and higher total body fat was strongly associated with higher total-C and LDL. Framingham risk scores were < 2% in both groups. CONCLUSIONS: In this cohort of non-obese African women HDL and TG, but not LDL, were adversely associated with HIV infection. As HDL is a strong predictor of cardiovascular (CV) events in women, this HIV-associated difference may confer increased risk for CV disease in HIV-infected women.

Effect of HIV infection on body composition and fat distribution in Rwandan women.

OBJECTIVE: To assess the association of HIV infection with body weight and composition in Rwandan women. DESIGN: Body weight and composition, the latter determined by bioelectrical impedance analysis (BIA) and by anthropometry, were compared in 620 HIV-positive and 211 HIV-negative participants. Associations of HIV with body composition were assessed, and t tests compared the groups. RESULTS: HIV-positive women were younger (-7.0 years, P < .001) and shorter (-2.1 cm, P < .001). Mean body weight, body mass index (BMI), total body fat, and waist-to-hip ratio (WHR) were similar. Mean fat-free mass was 2.5% greater in HIV-negative participants, and 19% of HIV-positive group had BMI <18.5 kg/m(2) versus 26% of the HIV-negative group (P < .05). CD4 counts and body composition were not associated. CONCLUSIONS: Malnutrition was common in this cohort of Rwandan women. However, HIV infection was not associated with nutritional status. Factors other than malnutrition may influence quality-of-life outcomes in HIV-infected Rwandan women. Initiatives to improve nutritional status should be population-wide and not restricted to the HIV-infected population.

The TDR MOOC training in implementation research: evaluation of feasibility and lessons learned in Rwanda.

BACKGROUND: Hypertension (HTN) affects nearly 1 billion people globally and is a major cause of morbidity and mortality. In low- and middle-income countries (LMICs), HTN represents an unmet health care gap that can be addressed by strengthening national health care systems. The National Heart, Lung, and Blood Institute recently funded the T4 Translation Research Capacity Building Initiative in Low Income Countries (TREIN) program to build capacity in dissemination and implementation (D&I) research in HTN in LMICs. The Special Programme for Research and Training in Tropical Diseases (TDR) at the World Health Organization (WHO) recently developed a massive open online course (MOOC) to train in D&I. Herein, we report on the use of the TDR WHO MOOC in D&I for the TREIN program in Rwanda, assessing feasibility of the MOOC and D&I competencies after MOOC training. METHODS: Participants in one-group MOOC training completed pre- and post-training questionnaires to assess dissemination and implementation (D&I) competency outcomes and feasibility. D&I competencies were measured by use of a scale developed for a US-based training program, with the change in competency scores assessed by paired t test. Feasibility was measured by completion of homework and final project assignment and analyzed using descriptive statistics. RESULTS: Of the 92 trainees enrolled, 35 (38%) completed all MOOC components. D&I competency scores showed strong evidence of improvements from pre- to post-test. The full-scale average score improved by an average of 1.09 points, representing an effect size of 1.25 (CI 0.48-2.00); all four subscales also showed strong evidence of improvements. Trainees reported challenges to MOOC course completion that included technological issues (i.e., limited internet access) and competing demands (i.e., work, family). CONCLUSIONS: In the context of LMIC training, the MOOC course was feasible and course completion showed improvement in D&I competency scores. While the program was designed with a focus on training for tropical diseases, there is potential for scalability to a wider audience of health care researchers, workers, administrators, and policymakers in LMIC interested in D&I research in non-communicable diseases.

Knowledge about modifiable risk factors for non-communicable diseases adults living with HIV in Rwanda.

BACKGROUND: Non-communicable diseases (NCD) are of international public health concern. Of more concern are people living with HIV (PLHIV), who have the increased risk of developing NCDs, such as hypertension, stroke and diabetes. Research has revealed that there is a relationship between knowledge of NCD risk factors and risk perceptions in the general population. Therefore, an assessment of PLHIV's NCD risk factors knowledge is quite critical, to design effective NCD prevention programmes. OBJECTIVE: To assess the level of knowledge of modifiable risk factors for NCDs and its associated factors among adults living with HIV in Rwanda. METHODS: A cross-sectional quantitative design was used to collect the data. The study targeted PLHIV who visited the out-patients' public health centres in three purposively selected provinces of Rwanda. The knowledge assessment questionnaire relating to risk factors for chronic diseases of lifestyle was used to collect the data. Data were analysed using SPSS version 23. RESULTS: Of the 794 respondents, 64.6% were women, and the mean age was 37.9 (±10.8) years. The results revealed that the majority of the respondents (65.0%) had low levels of knowledge about NCD risk factors, while some (35.6%) were of the opinion that they had a low risk of contracting NCDs. Good knowledge was significantly associated with high educational status, a low CD4+ cell count (< 350 cells/mm3) and normotension. CONCLUSION: The current study findings highlight the need for comprehensive health education, to raise awareness of non-communicable diseases' risk factors for adults living with HIV in Rwanda.

Dissemination and Implementation Program in Hypertension in Rwanda: Report on Initial Training and Evaluation.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide and in low- and middle-income countries, and hypertension (HTN) is a major risk factor for CVD. Although effective evidence-based interventions for control of HTN in high-income countries exist, implementation of these in low- and middle-income countries has been challenging due to limited capacity and infrastructure for late-phase translational research. In Rwanda, the 2015 STEPS NCD (STEPwise Approach to Surveillance of Noncommunicable Diseases) risk survey reported an overall prevalence of HTN of 15% (95% confidence interval [CI]: 13.8 to 16.3) for those ages 15 to 64 years; prevalence increased with increasing age to 39% (95% CI: 35.7 to 43.1) for those ages 55 to 64 years; CVD was the third most common cause of mortality (7%). Suboptimal infrastructure and capacity in Rwanda hinders research and community knowledge for HTN control. OBJECTIVES: To address the issue of suboptimal capacity to implement evidence-based interventions in HTN, this project was designed with the following objectives: 1) to develop a regional needs assessment of infrastructure for dissemination and implementation (D & I) strategies for HTN-CVD control; 2) to develop HTN-CVD research capacity through creation of countrywide resources such as core research facilities and training in the fields of HTN-CVD, D & I, and biostatistics; and 3) to engage and train multiple stakeholders in D & I and HTN-CVD evidence-based interventions. METHODS: A weeklong training program in HTN-CVD, biostatistics, and D & I was conducted in Rwanda in August 2018, and pre- and post-D & I training competency questionnaires were administered. RESULTS: Questionnaire results show a statistically significant increase in D & I knowledge and skills as a result of training (full scale pre- to post-test scores: 2.12 ± 0.78 vs. 3.94 ± 0.42; p < 0.0001). CONCLUSIONS: Using principles of community engagement and train-the-trainer methods, we will continue to adapt guidelines and treatments for HTN-CVD developed in high-income countries to the context of Rwanda with the goal of establishing a sustainable platform to address the burden of disease from HTN-CVD.

Exercise training reduces central adiposity and improves metabolic indices in HAART-treated HIV-positive subjects in Rwanda: a randomized controlled trial.

As HAART becomes more accessible in sub-Saharan Africa, metabolic syndromes, body fat redistribution (BFR), and cardiovascular disease may become more prevalent. We conducted a 6-month, randomized controlled trial to test whether cardiorespiratory exercise training (CET), improves metabolic, body composition and cardiorespiratory fitness parameters in HAART-treated HIV(+) African subjects with BFR. Six months of CET reduced waist circumference (-7.13 +/- 4.4 cm, p < 0.0001), WHR (-0.10 +/- 0.1, p < 0.0001), sum skinfold thickness (-6.15 +/- 8.2 mm, p < 0.0001) and % body fat mass (-1.5 +/- 3.3, p < 0.0001) in HIV(+)BFR(+)EXS. Hip circumference was unchanged in non-exercise control groups. CET reduced fasting total cholesterol (-0.03 +/- 1.11 mM, p < 0.05), triglycerides (-0.22 +/-0.48 mM, p < 0.05) and glucose levels (-0.21 +/- 0.71 mM, p < 0.05) (p < 0.0001). HDL-, LDL-cholesterol and HOMA values were unchanged after CET. Interestingly, HIV(+) subjects randomized to non-exercising groups experienced increases in fasting plasma glucose levels, whereas HIV seronegative controls did not (p < 0.001). Predicted VO(2) peak increased more in the HIV(+)BFR(+)EXS than in all other groups (4.7 +/- 3.9 ml/kg/min, p < 0.0001). Exercise training positively modulated body composition and metabolic profiles, and improved cardiorespiratory fitness in HAART-treated HIV(+) Africans. These beneficial adaptations imply that exercise training is a safe, inexpensive, practical, and effective treatment for evolving metabolic and cardiovascular syndromes associated with HIV and HAART exposure in resource-limited sub-Saharan countries, where treatment is improving, morbidity and mortality rates are declining, but where minimal resources are available to manage HIVand HAART-associated cardiovascular and metabolic syndromes.

Health-related quality of life and associated factors in adults living with HIV in Rwanda.

In Rwanda, as in other sub-Saharan African (SSA) countries, life expectancy of people living with HIV (PLWH) has increased dramatically as a result of combined antiretroviral therapy (cART). People living with HIV can now live longer but with increasing rates of non-communicable diseases (NCDs). Thus, prevention of NCD comorbidities in PWLHI is crucial to maintain and gain health-related benefits and to maximise the health-related quality of life (HRQOL) in the long-term management of PLWH. This study determines the association between physical and mental health-related dimensions of quality of life (QOL) with behavioural and biological risk factors, after controlling socio-demographic and HIV-related factors in adults living with HIV in Rwanda. A cross-sectional study using the WHO STEPwise approach and Kinyarwanda version of the MOS-HIV Health Survey, risk factors for NCDs and HRQOL were analysed for 794 PLWH, both HIV+ on ART and ART-naïve. Multiple regression analysis was used to examine the relationship between CMD risk factors and physical health and mental health summary scores. A total of 794 participants were interviewed. The mean age of the sample was 37.9 (±10.8) years and the majority of the participants were women (n = 513; 64.6%). About 16.2% reported daily smoking, 31.4% reported harmful alcohol use and 95% reported insufficient consumption of vegetables and fruits while 26.1% reported being physically inactive. 18.4% were overweight 43.4% had abdominal obesity, i.e. waist-hip-ratio (WHR) ≥0.95 in males and 0.85 in females. High blood pressure (HBP), i.e. systolic blood pressure (SBP) of ≥140 mmHg, or diastolic blood pressure (DBP) ≥90 mmHg was 24.4%. The results reveal that mean physical health summary and mental health summary score values were 63.96 ± 11.68 and 53.43 ± 10.89, respectively. While participants indicated that tobacco users and those who had abdominal obesity reported poor mental HRQOL, physical inactivity and hypertension have a negative impact on physical HRQOL. In addition, certain socio-demographic and HIV-related variables - specifically being unmarried, lack of HIV disclosure and low CD4 count (less 350 cell counts /mm3) - were associated with significantly lower mental and physical dimensions of quality of life. The results of this study reveal that behavioural and biological risk factors for NCDs were significantly associated with a lower HRQOL. These research findings also suggest that the assessment of the association between behavioural and biological risk factors for NCDs and a HRQOL provides opportunities for targeted counselling and secondary prevention efforts, so that health care providers can implement strategies that have a significant impact on the HRQOL.

HIV treatment is associated with a two-fold higher probability of raised triglycerides: Pooled Analyses in 21 023 individuals in sub-Saharan Africa.

BACKGROUND: Anti-retroviral therapy (ART) regimes for HIV are associated with raised levels of circulating triglycerides (TG) in western populations. However, there are limited data on the impact of ART on cardiometabolic risk in sub-Saharan African (SSA) populations. METHODS: Pooled analyses of 14 studies comprising 21 023 individuals, on whom relevant cardiometabolic risk factors (including TG), HIV and ART status were assessed between 2003 and 2014, in SSA. The association between ART and raised TG (>2.3 mmol/L) was analysed using regression models. FINDINGS: Among 10 615 individuals, ART was associated with a two-fold higher probability of raised TG (RR 2.05, 95% CI 1.51-2.77, I2=45.2%). The associations between ART and raised blood pressure, glucose, HbA1c, and other lipids were inconsistent across studies. INTERPRETATION: Evidence from this study confirms the association of ART with raised TG in SSA populations. Given the possible causal effect of raised TG on cardiovascular disease (CVD), the evidence highlights the need for prospective studies to clarify the impact of long term ART on CVD outcomes in SSA.

Assessment of quality of life in HAART-treated HIV-positive subjects with body fat redistribution in Rwanda.

BACKGROUND: The introduction of HAART has initially improved the quality of life (QoL) of HIV-positive (HIV+) patients, however body fat redistribution (BFR) and metabolic disorders associated with long-term HAART use may attenuate this improvement. As access to treatment improves in sub-Saharan Africa, the disfiguring nature of BFR (peripheral atrophy and/or central adiposity) may deter treatment adherence and initiatives and decrease QoL. We examined the relationship between BFR and domains of QoL in HAART-treated HIV+ African men and women with (HIV+BFR, n = 50) and without (HIV+noBFR, n = 50) BFR in Rwanda. RESULTS: HIV+ subjects with BFR were less satisfied with their body image (4.3 +/- 0.1 versus 1.5 +/- 0.2; p < .001), self-esteem and social life (4.1 +/- 1.4 versus 2.1 +/- 0.3; p = 0.003). HIV+BFR were more ashamed in public (4.5 +/- 1.2 versus 1.1 +/- 1.1), reported less confident about their health (4.6 +/- 1.4 versus 1.5 +/- 1.2) and were frequently embarrassed due to body changes (4.1 +/- 1.1 versus 1.1 +/- 0.9) (p < .001) than HIV+noBFR. HIV+ Rwandan women with BFR reported more dissatisfaction with psychological (8.3 +/- 2.9 versus 13.7 +/- 1.9), social relationships (6.9 +/- 2.3 versus 11.1 +/- 4.1) and HIV HAART-specific domain of wellbeing (3.1 +/- 4.8 versus 6.3 +/- 3.6) (p < .001). Age was associated with independence (r2 = 0.691; p = 0.009) and marital status was associated with psychological (r2 = 0.593; p = 0.019) and social relationships (r2 = 0.493; p = 0.007). CD4 count (r2 = 0.648; p = 0.003) and treatment duration (r2 = 0.453; p = 0.003) were associated with HIV HAART-specific domain of wellbeing. HIV+ Rwandan women with BFR were significantly more affected by abdominal adiposity (p < .001), facial and buttocks atrophy (p < .05) than HIV+ men with BFR. CONCLUSION: Body fat alterations negatively affect psychological and social domains of quality of life. These symptoms may result in stigmatization and marginalization mainly in HAART-treated African women, adversely affecting HAART adherence and treatment initiatives. Efforts to evaluate self-perceived body fat changes may improve patients' wellbeing, HAART adherence and treatment outcomes and contribute towards stability in quality of life continuum.

Health promotion needs of physically disabled individuals with lower limb amputation in Rwanda.

PURPOSE: The objectives of the study were to identify the health-related behaviors among physically disabled individuals with lower limb amputation resident in Rwanda, the factors that influenced these behaviors, and the major issues that should be targeted in health promotion programs for physically disabled individuals with lower limb amputation. METHOD: A cross-sectional survey, utilizing a self-administered questionnaire, was carried out among 334 lower limb amputees who volunteered to take part in the study. In addition, a sub-sample of 15 participants was purposely selected for in-depth face-to-face interviews. RESULTS: Many participants did not engage in physical exercises (64.7%). Others abused alcohol on daily basis (14.4%), smoked 11-20 cigarettes daily (13.2%), and used recreational drugs such as marijuana, opium and cocaine (9.6%). There were significant associations between the age group of the participants and participation in exercises (P=0.001), and consuming alcohol, tobacco and recreational drugs (P=0.001). In-depth interviews revealed factors influencing the behavior of participants. CONCLUSIONS: Participants were found to be at risk of secondary complications because of poor lifestyle choices. There is a need to develop and promote wellness-enhancing behaviors in order to enhance the health status of physically disabled individuals in Rwanda who have lower limb amputations.

Prevalence of shingles and its association with PTSD among HIV-infected women in Rwanda.

OBJECTIVE: To examine the prevalence of reported shingles in the last 6 months and its association with post-traumatic stress disorder (PTSD), depression and severity of HIV disease in Rwandan women with HIV. SETTINGS: This cross-sectional study was conducted as part of the Rwanda Women's Interassociation Study and Assessment (RWISA), an observational cohort study designed to assess the impact of HIV and residual factors from experiencing rape in the 1994 genocide in Rwandan women. Participants were recruited through grassroots women's associations of people living with HIV infection and clinical care sites for HIV infection. Most participants (58.5%, n=405/692) had PTSD. PARTICIPANTS: This cross-sectional analysis was conducted in 710 HIV-infected women enrolled in RWISA. Inclusion criteria were: age >15 years, informed consent, HIV test, ability to complete the interview in the local language, travel to and from the research site and participate in a baseline outpatient visit, and being naive to antiretroviral therapy at enrolment. PRIMARY AND SECONDARY OUTCOME MEASURES: The outcome of interest was self-reported shingles in the past 6 months. The exposure was PTSD defined using the cross-culturally validated Harvard Trauma Questionnaire. RESULTS: Overall prevalence of reported shingles in the past 6 months was 12.5% (n=89/710). There was an inverse relationship between shingles prevalence and immunological status: 7.6%, 12.3% and 16.7% of women with CD4 >350, 200-350 and <200 cells/µL, respectively, reported singles (p=0.01). In multivariate analysis, PTSD (aOR 1.7; 95% CI 1.02 to 2.89) and low CD4 (aOR 2.4; 95% CI 1.23 to 4.81) were independently associated with reported shingles in the past 6 months. CONCLUSIONS: Our study found a significant independent relationship between PTSD and reported shingles, suggesting that PTSD may be associated with immune compromise that can result in herpes zoster reactivation. Further study is needed. It also confirmed previous findings of a strong relationship between shingles and greater immunosuppression in women with HIV infection.

Use of Traditional Botanical Medicines During Pregnancy in Rural Rwanda.

OBJECTIVE: To evaluate the perceptions of healthcare and traditional medicine providers regarding the type, indications, side effects, and prevalence of traditional medicine use amongst pregnant women in a rural Rwandan population. METHODS: Six focus groups with physicians, nurses, and community health workers and four individual in-depth interviews with traditional medicine providers were held. Qualitative data was gathered using a structured questionnaire querying perceptions of the type, indications, side effects, and prevalence of use of traditional medicines in pregnancy. RESULTS: The healthcare provider groups perceived a high prevalence of traditional botanical medicine use by pregnant women (50-80%). All three groups reported similar indications for use of the medicines and the socioeconomic status of the pregnant women who use them. The traditional medicine providers and the healthcare providers both perceived that the most commonly used medicine is a mixture of many plants, called Inkuri. The most serious side effect reported was abnormally bright green meconium with a poor neonatal respiratory drive. Thirty-five traditional medicines were identified that are used during pregnancy. CONCLUSION: Perceptions of high prevalence of use of traditional medicines during pregnancy with possible negative perinatal outcomes exist in areas of rural Rwanda.

Insulin resistance change and antiretroviral therapy exposure in HIV-infected and uninfected Rwandan women: a longitudinal analysis.

BACKGROUND: We longitudinally assessed predictors of insulin resistance (IR) change among HIV-uninfected and HIV-infected (ART-initiators and ART-non-initiators) Rwandan women. METHODOLOGY: HIV-infected (HIV+) and uninfected (HIV-) women provided demographic and clinical measures: age, body mass index (BMI) in Kg/(height in meters)2, Fat-Mass (FMI) and Fat-Free-Mass (FFMI) index, fasting serum glucose and insulin. Homeostasis Model Assessment (HOMA) was calculated to estimate IR change over time in log10 transformed HOMA measured at study enrollment or prior to ART initiation in 3 groups: HIV- (n = 194), HIV+ ART-non-initiators (n=95) and HIV+ ART-initiators (n=371). ANCOVA linear regression models of change in log10-HOMA were fit with all models included the first log10 HOMA as a predictor. RESULTS: Mean±SD log10-HOMA was -0.18±0.39 at the 1st and -0.21±0.41 at the 2nd measure, with mean change of 0.03±0.44. In the final model (all women) BMI at 1st HOMA measure (0.014; 95% CI=0.006-0.021 per kg/m2; p<0.001) and change in BMI from 1st to 2nd measure (0.024; 95% CI=0.013-0.035 per kg/m2; p<0.001) predicted HOMA change. When restricted to subjects with FMI measures, FMI at 1st HOMA measure (0.020; 95% CI=0.010-0.030 per kg/m2; p<0.001) and change in FMI from 1st to 2nd measure (0.032; 95% CI=0.020-0.043 per kg/m2; p<0.0001) predicted change in HOMA. While ART use did not predict change in log10-HOMA, untreated HIV+ women had a significant decline in IR over time. Use or duration of AZT, d4T and EFV was not associated with HOMA change in HIV+ women. CONCLUSIONS: Baseline BMI and change in BMI, and in particular fat mass and change in fat mass predicted insulin resistance change over ~3 years in HIV-infected and uninfected Rwandan women. Exposure to specific ART (d4T, AZT, EFV) did not predict insulin resistance change in ART-treated HIV-infected Rwandan women.
