Background: Women's responses to partner violence are influenced by a complex constellation of factors including: psychological attachment to the partner; context of the abuse; and structural factors, all of which shape available options for women outside of the relationship. Objective: To describe women's responses to physical partner violence; and to understand the role of women's economic resources on their responses. Methods: Cross-sectional data from Dar es Salaam and Mbeya, Tanzania. Multivariate logistic regression was used to explore the relationship between women's economic resources and their responses to violence. Results: In both sites, among physically abused women, over one-half experienced severe violence; approximately two-thirds had disclosed the violence; and approximately 40% had sought help. Abused women were more likely to have sought help from health services, the police and religious leaders in Dar es Salaam, and from local leaders in Mbeya. Economic resources did not facilitate women's ability to leave violent partners in Dar es Salaam. In Mbeya, women who jointly owned capital assets were less likely to have left. In both sites, women's sole ownership of capital assets facilitated help-seeking. Conclusion: Although support services are being scaled-up in Tanzania, efforts are needed to increase the acceptability of accessing such services. © 2017 The Author(s).

Background: Prevention of mother to child transmission of HIV (PMTCT) has been scaled, to more than 90% of health facilities in Tanzania. Disclosure of HIV results to partners and their participation is encouraged in the program. This study aimed to determine the prevalence, patterns and predictors of HIV sero-status disclosure to partners among HIV positive pregnant women in Morogoro municipality, Tanzania. Methods. A cross sectional study was conducted in March to May 2010 among HIV-positive pregnant women who were attending for routine antenatal care in primary health care facilities of the municipality and had been tested for HIV at least one month prior to the study. Questionnaires were used to collect information on possible predictors of HIV disclosure to partners. Results: A total of 250 HIV-positive pregnant women were enrolled. Forty one percent (102) had disclosed their HIV sero-status to their partners. HIV-disclosure to partners was more likely among pregnant women who were < 25 years old [Adjusted odds ratio (AOR) = 2.2; 95% CI: 1.2-4.1], who knew their HIV status before the current pregnancy [AOR = 3.7; 95% CI: 1.7-8.3], and discussed with their partner before testing [AOR = 6.9; 95% CI: 2.4-20.1]. Dependency on the partner for food/rent/school fees, led to lower odds of disclosure to partners [AOR = 0.4; 95% CI: 0.1-0.7]. Nine out of ten women reported to have been counseled on importance of disclosure and partner participation. Conclusions: Six in ten HIV positive pregnant women in this setting had not disclosed their results of the HIV test to their partners. Empowering pregnant women to have an individualized HIV-disclosure plan, strengthening of the HIV provider initiated counseling and testing and addressing economic development, may be some of the strategies in improving HIV disclosure and partner involvement in this setting. © 2013 Kiula et al.; licensee BioMed Central Ltd.

Malaria Journal | Year: 2013

Background: Studies conducted thus far have demonstrated that the malaria vaccine (RTS,S) has a promising safety profile. Within the context of planning for future vaccine trials and for the purpose of building on previous research that has been undertaken in sub-Saharan Africa with regard to community perceptions about clinical studies, this research aimed to explore the community perceptions on the secondary health benefits established by the malaria vaccine trials (RTS,S Phase 2 and Phase 3) at the Korogwe site in Tanzania. Methods. An exploratory qualitative study design was used. Participants were recruited from the Korogwe site. Sampling techniques were purposive and random. A total of five focus group discussions and six in-depth interviews were conducted. Interview guides with open-ended questions were employed to collect data. Male and female parents whose infants participated and those whose infants did not participate in the trials, health workers and community leaders were interviewed. Thematic analysis framework was used to analyse the data. Results: The activities of a malaria vaccine project appeared to be well known to the community. Respondents had largely positive views towards the secondary health benefits which have been established by malaria vaccine trials. The project has led to a massive investment in health care infrastructure and an improvement in health care services across the study areas. The project was perceived by the community to have established major secondary health benefits. Misconceptions amongst respondents, especially with regard to blood samples, were also observed in this study. Conclusion: Despite some misconceptions with regard to the conduct of malaria vaccine trials, especially on blood sampling, generally this study observed that most participants were positive about the secondary health benefits brought about by the malaria vaccine trials in Korogwe. © 2013 Liheluka et al.; licensee BioMed Central Ltd.

Methods. A cross-sectional study design was conducted from April to May, 2012. A systematic sampling method was employed to select 422 study subjects. A pre-tested SERVQUAL questionnaire was used to collect data and one-sample t-test was employed to identify patients' level of satisfaction and principal component analysis to identify key items that measure quality of care.Results: Patients' level of satisfaction mean gap score was (-2.88 ± 3.1) indicating overall dissatisfaction with the quality of care. The level of dissatisfaction in the five service dimensions were as follows: assurance (-0.47), reliability (-0.49), tangible (-0.52), empathy (-0.55), and responsiveness (-0.72).Conclusion: Patients attending OPD at Mwananyamala hospital demonstrates an overall dissatisfaction on quality of care. Hospital management should focus on: improvement on communication skills among OPD staff in showing compassion, politeness and active listening, ensure availability of essential drugs, and improvement on clinicians' prescription skills.Background: Enhancing quality of health care delivered in public health facilities in developing countries is a key prerequisite to increase utilization and sustainability of health care services in the population. The aim of the study was to determine patients' level of satisfaction on the quality of health care delivered at the out-patient department (OPD) in Mwananyamala hospital in Dar es Salaam, Tanzania. © 2014 Khamis and Njau; licensee BioMed Central Ltd.

Background:Q fever is a common cause of febrile illness and community-acquired pneumonia in resource-limited settings. Coxiella burnetii, the causative pathogen, is transmitted among varied host species, but the epidemiology of the organism in Africa is poorly understood. We conducted a systematic review of C. burnetii epidemiology in Africa from a "One Health" perspective to synthesize the published data and identify knowledge gaps.Methods/Principal Findings:We searched nine databases to identify articles relevant to four key aspects of C. burnetii epidemiology in human and animal populations in Africa: infection prevalence; disease incidence; transmission risk factors; and infection control efforts. We identified 929 unique articles, 100 of which remained after full-text review. Of these, 41 articles describing 51 studies qualified for data extraction. Animal seroprevalence studies revealed infection by C. burnetii (≤13%) among cattle except for studies in Western and Middle Africa (18-55%). Small ruminant seroprevalence ranged from 11-33%. Human seroprevalence was <8% with the exception of studies among children and in Egypt (10-32%). Close contact with camels and rural residence were associated with increased seropositivity among humans. C. burnetii infection has been associated with livestock abortion. In human cohort studies, Q fever accounted for 2-9% of febrile illness hospitalizations and 1-3% of infective endocarditis cases. We found no studies of disease incidence estimates or disease control efforts.Conclusions/Significance:C. burnetii infection is detected in humans and in a wide range of animal species across Africa, but seroprevalence varies widely by species and location. Risk factors underlying this variability are poorly understood as is the role of C. burnetii in livestock abortion. Q fever consistently accounts for a notable proportion of undifferentiated human febrile illness and infective endocarditis in cohort studies, but incidence estimates are lacking. C. burnetii presents a real yet underappreciated threat to human and animal health throughout Africa. © 2014 Vanderburg et al.

BMC Pregnancy and Childbirth | Year: 2016

Background: Both short and long interpregnancy intervals have been associated with an increased risk of adverse pregnancy outcomes. There is limited information about the impact of interpregnancy interval on pregnancy (IPI) outcomes in Tanzania. The objective of this study was to assess the effect of IPI on adverse pregnancy outcomes. Methods: We performed a retrospective cohort study using maternally-linked data from Kilimanjaro Christian Medical Centre (KCMC) birth registry. A total of 17,030 singlet births from women who delivered singleton infant at KCMC from 2000 to 2010 were studied. Women with multi-fetal gestations and those who were referred from rural areas for various medical reasons were excluded. Outcome variables were preterm birth, low birth weight infants and perinatal death. A multiple logistic regression was used to assess the association between IPI and pregnancy outcomes. Results: The median IPI was 36 months. Compared with IPIs of 24-36 months (referent group), short interpregnancy intervals (<24 months) was associated with preterm delivery (OR 1.52; 95 % CI 1.31-1.74); low birth weight (OR 1.61; 95 % CI 1.34-1.72) and perinatal death, (OR 1.63; 95 % CI 1.22-1.91). The IPI of 37-59 months or longer were also associated with higher risks of preterm birth and low birth weight, but not with perinatal death. Conclusions: Our study confirmed that both short and long IPI are independent risk factors for adverse pregnancy outcomes. These finding emphasize the importance of providing support for family planning programs which will support optimal IPI and improve pregnancy outcomes. © 2016 The Author(s).

Objectives: Cryptococcal antigen (CRAG) screening at antiretroviral therapy (ART) initiation and pre-emptive antifungal treatment for those testing positive could prevent many cases of cryptococcal meningitis (CM). To investigate whether CRAG screening would be feasible in Tanzania, we conducted a cross-sectional study measuring CRAG prevalence in ART clinic patients and comparing the novel lateral flow assay (LFA) with the cryptococcal latex agglutination (LA) test. Methods: Consecutive HIV-infected outpatients with CD4 counts <200 cells/μL, who were ART naive or had been on ART for <6 months, were screened for CRAG using the LA and LFA kits. For further assay validation, HIV-infected inpatients with suspected cryptococcal disease were also tested using the LA and LFA kits. Results: Cryptococcal antigen was detected in seven of 218 ART clinic attendees (3%). Six patients (5%) with CD4 cell counts ≤100 cells/μL (n = 124) were CRAG-positive. Agreement between the LA and LFA test in the 218 outpatients was 100%. Another 101 inpatients were tested for CRAG, of whom 56 (55%) were CRAG-positive on both the LA and LFA tests. One patient was positive using the LFA test but negative on the LA test. The overall agreement between the two assays was 99.7%, kappa coefficient 0.99 (standard error 0.06, P < 0.001). Conclusions: Five percentage of ART clinic patients with CD4 cell counts ≤100 cells/μL in northern Tanzania had asymptomatic cryptococcal antigenaemia, suggesting that CRAG screening would be worthwhile in the Tanzanian ART programme. The LFA is a reliable, cheap and practical alternative to LA for detection of CRAG. © 2013 John Wiley & Sons Ltd.

Journal of Interpersonal Violence | Year: 2014

Estimates of the effect of employment on women’s risk of partner violence in cross-sectional studies are subject to potential “self-selection bias.” Women’s personal choice of whether to pursue employment or not may create fundamental differences between the group of women who are employed and those who are not employed that standard regression methods cannot account for even after adjusting for confounding. The aim of this study is to demonstrate the utility of propensity score matching (PSM), a technique used widely in econometrics, to address this bias in cross-sectional studies. We use PSM to estimate an unbiased effect-size of women’s employment on their risk of experiencing partner violence in urban and rural Tanzania using data from the 2010 Tanzania Demographic and Health Survey (DHS). Three different measures of women’s employment were analyzed: whether they had engaged in any productive work outside of the home in the past year, whether they received payment in cash for this productive work, and whether their employment was stable. Women who worked outside of the home were significantly different from those who did not. In both urban and rural Tanzania, women’s risk of violence appears higher among women who worked in the past year than among those who did not, even after using PSM to account for underlying differences in these two groups of women. Being paid in cash reversed this effect in rural areas whereas stability of employment reduced this risk in urban centers. The estimated size of effect varied by type of matching estimator, but the direction of the association remained largely consistent. This study’s findings suggest substantial self-selection into employment. PSM methods, by compensating for this bias, appear to be a useful tool for estimating the relationship between women’s employment and partner violence in cross-sectional studies. © The Author(s) 2014.

Anopheles gambiae s.l. are important malaria vectors, but little is known about their genomic variation in the wild. Here, we present inter- and intraspecies analysis of genome-wide RADseq data, in three Anopheles gambiae s.l. species collected from East Africa. The mosquitoes fall into three genotypic clusters representing described species (A. gambiae, A. arabiensis, and A. merus) with no evidence of cryptic breeding units. Anopheles merus is the most divergent of the three species, supporting a recent new phylogeny based on chromosomal inversions. Even though the species clusters are well separated, there is extensive shared polymorphism, particularly between A. gambiae and A. arabiensis. Divergence between A. gambiae and A. arabiensis does not vary across the autosomes but is higher in X-linked inversions than elsewhere on X or on the autosomes, consistent with the suggestion that this inversion (or a gene within it) is important in reproductive isolation between the species. The 2La/2L+a inversion shows no more evidence of introgression between A. gambiae and A. arabiensis than the rest of the autosomes. Population differentiation within A. gambiae and A. arabiensis is weak over approximately 190-270 km, implying no strong barriers to dispersal. Analysis of Tajima's D and the allele frequency spectrum is consistent with modest population increases in A. arabiensis and A. merus, but a more complex demographic history of expansion followed by contraction in A. gambiae. Although they are less than 200 km apart, the two A. gambiae populations show evidence of different demographic histories. © 2014 The Author.

Pediatric Diabetes | Year: 2013

Objective: There are an estimated 1000 children with diabetes in Tanzania. Recently, the first two pediatric endocrinologists, trained in the European Society for Paediatric Endocrinology (ESPE)/International Society for Paediatric and Adolescent Diabetes (ISPAD) program in Nairobi, Kenya, entered practice. The purpose of this study was to prospectively assess the impact of a 6-month diabetes management and education program on glycemic control and acute complications in children and adolescents in Tanzania. Research design and methods: Eighty-one patients aged 3-19yr were enrolled. All were on split-dose Insulatard (Neutral Protamine Hagedorn) and Actrapid (soluble, regular) insulin, and were given three glucose test strips per week. Children were seen in clinic an average of six times over 6months and received 3h of diabetes education. A structured questionnaire evaluated social demographic data and acute complications. Results: Despite regular clinic attendance, diabetes education, and provision of insulin, hemoglobin A1c (HbA1c) levels did not improve. Four children (5%) had HbA1c 7.5%, 22 (28%) HbA1c 7.5-10%, 9 (24%) HbA1c 11-12.5%, and 36 (44%) HbA1c >12.5%. There was a substantial reduction in severe hypoglycemia, with 17% of subjects experiencing this acute complication compared to 52% in the 6months prior to study enrolment. Six children were admitted in diabetic ketoacidosis during the study compared to three during the previous 6months. Twenty-six children (36%) reported missing >6 doses of insulin (but only two lacked insulin). Conclusions: Diabetes education significantly reduced the risk of severe hypoglycemia, but better glycemic control of diabetes was not attained. Further study is needed to explore factors to improve glycemic control including increased testing, or perhaps different insulin regimens. © 2013 John Wiley & Sons A/S.
