RESUMO

Background: Breast milk provides infants with complete nutrition for immune development and protection against childhood diseases and associated mortality. Early initiation of breastfeeding (EIBF) aids in providing colostrum to newborns, providing protection against infection, and improving newborn and infant survival. Although Simiyu reported the lowest prevalence of EIBF in Tanzania, no study has investigated the factors associated with EIBF in this region. Objective: The study aimed to determine early breastfeeding initiation prevalence and associated factors among women of reproductive age in the Simiyu region. Methodology: We used data from a cross-sectional study conducted by AMREF Health Africa among 669 women of reproductive age (15-49 years) in the Simiyu region, Tanzania. An interviewer-administered questionnaire collected data on breastfeeding practices (including breastfeeding initiation) among others. A multilevel logistic regression analysis estimated the adjusted odds ratio (OR) and 95% confidence intervals (CI) for factors associated with EIBF. Results: The mean age of 669 women analyzed was 28.3 years (SD ± 6.8). The prevalence of EIBF was 62.2%, ranging from 52.7% in Bariadi district to 73.3% in Maswa district. Lower odds of EIBF were among women who had a caesarian section (OR = 0.41; 95% CI = 0.17-0.98) and those who gave birth to male children (OR = 0.57; 95%CI = 0.39-0.82) while higher odds of EIBF were among mothers who reported skin-to-skin contact (OR = 2.40; 95%CI = 1.53-3.83) and from Maswa district (OR = 2.73; 95%CI = 1.09-6.89). Conclusion: The prevalence of EIBF in the Simiyu region remains low (62%) relative to the global target of 70% by 2030 and varies by district. To promote EIBF in the region, good engagement and communication practices between mothers and healthcare providers should be emphasised in educating women about the importance of EIBF. Moreover, the practice of skin-to-skin contact between mother and child should be encouraged immediately after delivery.

RESUMO

The use of vaccines is one of the key tools in reversing the COVID-19 pandemic; however, various reports reported the low uptake of the vaccines. This study explored the barriers to the COVID-19 vaccine uptake among community members in Tanzania. A qualitative explorative study was conducted in December 2021 and April 2022 in eight regions of Tanzania. Focus group discussions (FGDs) and in-depth interviews (IDIs) were the methods of data collection. A total of 48 FGDs and 32 IDIs were conducted. Participants were aware of the COVID-19 disease and vaccines. The barriers to the COVID-19 vaccine non-uptake included receiving contradicting statements from top government leaders, vaccine preceded the education, myths towards vaccines, the presence of different types of vaccines, the process of getting the vaccine, the influence of social media and random people from the community, and vaccine conflicting religious beliefs. Despite being aware of the vaccine, the uptake of the COVID-19 vaccine is still low. Interventions that focus on increasing community knowledge about COVID-19 vaccines and addressing myths about the vaccines are needed.

RESUMO

COVID-19 is a major public health threat associated with increased disease burden, mortality, and economic loss to countries and communities. Safe and efficacious COVID-19 vaccines are key in halting and reversing the pandemic. Low confidence in vaccines has been one of the factors leading to hesitancy. We aimed to assess the COVID-19 vaccine confidence (safety and effectiveness), associated factors, and its effects on vaccine uptake among general community members in Tanzania. This was a community-based cross-sectional survey conducted from December 2021 to April 2022 in six regions of Tanzania mainland and two regions in Zanzibar. Participants were interviewed using an electronic questionnaire. Multiple logistic regression models estimated odds ratios (ORs) and 95% confidence interval (CI) for factors associated with vaccine confidence. All analyses were performed using SPSS version 25.0. The study enrolled 3470 general Tanzanian community members; their mean age was 40.3 (standard deviation ±14.9) years, and 34% were males. The proportion of COVID-19 vaccine confidence was 54.6%. Geographical region, residence area, COVID-19 disease risk perception, and good knowledge of COVID-19 vaccines were significantly associated with COVID-19 vaccine confidence. Confidence in COVID-19 vaccines was associated with over three times higher odds of vaccine uptake. Confidence in COVID-19 vaccines was low in Tanzania. Innovative community engagement strategies and region-specific interventions are needed to improve comprehensive knowledge and address community perceptions and attitudes toward COVID-19 vaccines.

RESUMO

COVID-19 is a major public health threat associated with the increased global burden of infectious diseases, mortality, and enormous economic loss to countries and communities. Safe and efficacious COVID-19 vaccines are crucial in halting the pandemic. We assessed the COVID-19 vaccine uptake and associated factors among community members from eight regions in Tanzania. The interviewer-administered questionnaire collected data. Multiple logistic regression models determined the factors associated with vaccine uptake. The median age of 3470 respondents was 37 years (interquartile range of 29-50 years) and 66% of them were females. Only 18% of them had received the COVID-19 vaccine, ranging from 8% in Dar es Salaam to 37% in Simiyu regions. A third (34%) of those vaccinated people did not know which vaccine they were given. Significantly higher rates of COVID-19 vaccine uptake were among the respondents aged 30+ years, males, and with a history of COVID-19 infection. Unfavorable perceptions about vaccine safety and efficacy lowered the rates of vaccine uptake. Setting-specific interventions and innovations are critical to improving vaccine uptake, given the observed differences between regions. Efforts are needed to increase vaccine uptake among women and younger people aged less than 30 years. Knowledge-based interventions should enhance the understanding of the available vaccines, benefits, target groups, and availability.

RESUMO

BACKGROUND: Human papilloma virus (HPV) is a sexually transmitted infection causing more than 80% of cervical cancers. WHO recommends using of sensitive screening methods like HPV-testing to timely prevent future morbidity and mortality from cervical cancer. Pilot studies have shown that HPV-testing is feasible and can be scaled in developing country like Tanzania. However, there is limited information on women understanding, reactions and psychological challenges following diagnosis of high risk HPV (HR-HPV). This study explored the knowledge of women on HPV and their experience after HPV positive results in Kilimanjaro, Tanzania. METHODS: The study was part of a larger study that assessed incidence and persistence of HR-HPV among women aged 18 years and above in Kilimanjaro. This was a cross sectional study conducted in Moshi municipal council among women who had HR-HPV positive results at enrollment. In-depth interviews were conducted with 13 randomly selected women who were attending for follow-up after enrollment. Interviews were conducted at the health facility and Atlas.ti.8 was used to analyze the data using thematic framework analysis. RESULTS: Women had knowledge on HPV infection but they had different reactions following receiving positive HPV results. Reaction toward the positive HPV results had two extremes; some women had psychological effect (hopeless, death sentence, having cancer, being shocked, failure to disclose and psychosexual effects) while others women explained positive results is good as they are identified earlier, will be followed up and it has made them plan to continue with cervical cancer screening in future. CONCLUSION: Women had knowledge on HPV, but positive results lead to negative and positive experiences by women. Clinicians and programs need to develop interventions and good strategies to minimize the psychological and social burden of testing positive for HPV.

RESUMO

BACKGROUND: Raising awareness of antimicrobial resistance is a cornerstone of action plans to tackle this global One Health challenge. Tools that can reliably assess levels of awareness of antibiotic resistance (ABR) among human or animal healthcare professionals (HCPs) are required to guide and evaluate interventions. METHODS: We designed and tested an ABR awareness scale, a self-administered questionnaire completed by human and animal HCPs trained to prescribe and dispense antibiotics in six countries-Ghana, Nigeria, Tanzania, Vietnam, Thailand and Peru. Questionnaires also elicited demographic, practice, and contextual information. Psychometric analysis for the scale followed Rasch Measurement Theory. Bivariate analysis was carried out to identify factors associated with awareness scores. RESULTS: Overall, 941 HCPs (625 human and 316 animal) from Ghana, Nigeria, Tanzania, Vietnam, Thailand and Peru were included in the study. The 23-item ABR awareness scale had high-reliability coefficients (0.88 for human and 0.90 for animal HCPs) but performed better within countries than across countries. Median ABR awareness scores were 54.6-63.5 for human HCPs and 55.2-63.8 for animal HCPs (scale of 0-100). Physicians and veterinarians scored higher than other HCPs in every country tested. HCPs in this study reported working in contexts with limited laboratory infrastructures. More than 95% of HCPs were interested in receiving information or training on ABR and antimicrobial stewardship. CONCLUSION: HCPs' awareness of ABR can be reliably assessed with this validated 23-item scale within the countries tested. Using the scale alongside context questions and objective measurement of practices is recommended to inform interventions to improve antibiotic use.

RESUMO

Cervical cancer is the most common female cancer in Eastern Africa, and the World Health Organization (WHO) recommends human papillomavirus (HPV)-based screening as a key element to eliminate the disease. In this cross-sectional study from Tanzania, we compared nine HPV-based cervical cancer screening strategies, including HPV testing at standard cut-off; HPV testing at increased viral load cut-offs; HPV testing with partial/extended genotyping, and HPV testing with visual inspection with acetic acid (VIA). We pooled data collected during 2008 to 2009 and 2015 to 2017 from 6851 women aged 25 to 65. Cervical cytology samples were HPV tested with Hybrid Capture 2, and HPV positive samples were genotyped with INNO-LiPA Extra II. Human immunodeficiency virus (HIV) testing and VIA were done according to local standards. We calculated sensitivity, specificity, positive and negative predictive value of screening strategies, with high-grade cytological lesions as reference, separately for women with and without HIV. HPV testing at standard cut-off (1.0 relative light units [RLU]) had highest sensitivity (HIV+: 97.8%; HIV-: 91.5%), but moderate specificity (HIV+: 68.1%; HIV-: 85.7%). Increasing the cut-off for HPV positivity to higher viral loads (5.0/10.0 RLU) increased specificity (HIV+: 74.2%-76.5%; HIV-: 89.5%-91.2%), with modest sensitivity reductions (HIV+: 91.3%-95.7%; HIV-: 83.5%-87.8%). Limiting test positivity to HPV types 16/18/31/33/35/45/52/58 improved specificity while maintaining high sensitivity (HIV+: 90.2%; HIV-: 81.1%). Triage with VIA and/or partial genotyping for HPV16/18 or HPV16/18/45 had low sensitivities (≤65%). In conclusion, HPV testing alone, or HPV testing with extended genotyping or increased viral load cut-offs, may improve cervical cancer screening in Sub-Saharan Africa.

RESUMO

The past two decades have seen unprecedented student demand for global health education through experiential and engaged learning within institutions of higher education in the United States. This demand created a need for innovative institutional partnerships. Since 2007, faculty from Cornell University's Global Health Program and Kilimanjaro Christian Medical University College (KCMUCo) have worked together to design, implement, and evaluate an innovative experiential learning program in global health and development policy. Since its inception, 176 Cornell undergraduates and 188 KCMUCo medical students have successfully engaged in the policy case study collaborative program and course, leading to the development of 75 policy case studies. This long-term partnership between Cornell and KCMUCo has led to an innovative cross-cultural teaching model, funding support, professional presentations for students and faculty, a visiting scholars program at Cornell, and new avenues for research and collaboration. Fifteen years of sustained partnership has required the navigation of several unique and complex challenges, providing the opportunity to reimagine and strengthen this program and partnership. The objective of this article is to share a powerful program model for global health training and education, and discuss the challenges, successes, and lessons learned through this continued collaboration.

RESUMO

BACKGROUND: Diabetes mellitus (DM) is a common comorbidity among people with tuberculosis (TB). Despite the availability of guidelines on how to integrate dual TB/DM in Tanzania, the practice of integration at various healthcare levels is unclear. OBJECTIVE: To explore the participants' experiences and perceptions on the pathway towards clinical management of dual TB/DM. METHOD: The research was carried out in Dar es Salaam, Iringa, and Kilimanjaro regions between January and February 2020. A qualitative, in-depth interview approach was used to collect participants' experiences and perspectives on the acquisition of dual TB/DM services at various levels of healthcare facilities. The information gathered were coded and classified thematically. RESULTS: The participants' perception of TB services within the healthcare facilities was positive due to the support they received from the healthcare providers. On the other hand, participants reported difficulty receiving management in various health facilities for each condition in terms of access to dual TB/DM care and access to DM medication. This was viewed as a significant challenge for the participants with dual TB/DM. CONCLUSIONS: The current disjunction and disruption in healthcare for people with dual TB/DM makes it difficult to access services at various levels of health facilities. For optimal clinical management for people with dual TB/DM, patient-centered strategies and integrated approaches are urgently needed.

RESUMO

INTRODUCTION: Viral load measurement is an important gold standard for monitoring anti-retroviral treatment among people living with human immunodeficiency virus. The optimal use of the viral load results for guiding antiretroviral therapy depends on timely availability of the results at the clinic. The objective of the current study was to evaluate the turnaround time and utilization of viral load results in the clinical decision process. METHODOLOGY: This was a retrospective cohort study which involved patients receiving cART from 1 August 2018 to 31 January 2017 at three clinics in Tanzania. Data was extracted from patient files at the clinics and relevant records were kept at the viral load determining laboratory. The data were analysed with the Statistical Package for Social Sciences version 20. RESULTS: 445 subjects had a viral load in test results and 88% had a viral load of > 1,000 copies/mL. The median duration on the current regimen was five years. Median time between the clinics receiving the results and communicating them to the patients was 40 days. Shorter turnaround time was observed for patients with virological failure (p = 0.003). A higher prevalence of virological failure was found in patients monitored at the Kilimanjaro Christian Medical Centre (KCMC) compared to the two primary health clinics (p = 0.04). CONCLUSIONS: The median viral load turnaround time was longer than stipulated by the national Tanzanian guidelines. Interventions that may reduce viral load turn-around-time, including point of care viral load testing, are needed to optimise monitoring of anti-retroviral therapy.

RESUMO

Objective: To assess the current Tanzania health facilities readiness in integrating clinical management of dual Tuberculosis (TB) and Diabetes Mellitus (DM) by using the Service Availability and Readiness Assessment (SARA) manual of the World Health Organization prior to implementing an integrated service model. Study design: Cross-sectional study. Methods: A needs assessment survey was conducted at varying levels of health care facilities. The SARA manual evaluated the service delivery outcomes in terms of availability of guidelines, medicines and diagnostic equipment, training of healthcare workers in providing TB and DM care, and patient record review. Data were analyzed using Statistical Package for Social Science version 26. Results: Among 29 health facilities selected, three were regional referral hospitals, eight were district hospitals and eighteen were health centers. Baseline investigations revealed that GeneXpert MTB/RIF machines were present in 10 (34.5%) facilities, and glycated hemoglobin devices were present in two (6.9%) facilities, while all health facilities had a glucometer. The presence of an attending medical doctor in 19 (65.5%) facilities and the presence of operating biochemistry analyzers in 15 (51.7%) facilities were two mandatory variables used to assess readiness. Among the various guidelines observed, none of the facilities had the 2016 DM guidelines. Overall, 15 (51.7%) health facilities were ready to integrate dual TB and DM services. Conclusion: Integrative TB/DM screening and management activities can be achieved only if integration initiatives are prioritized at all levels of health facilities and among health policy makers in Tanzania. At least half of the health facilities were prepared to integrate the management of dual TB/DM. However, there is an urgent need to mobilize significant resources to improve the integration in these facilities, such as management guidelines and diagnostics..

RESUMO

BACKGROUND: High-risk (HR) human papillomavirus (HPV) persistence is the most important risk factor for cervical cancer. We have assessed the type-specific HR HPV persistence among HIV positive and HIV negative Tanzanian women and factors associated with HR HPV persistence. METHODS: In a cohort study including 4080 Tanzanian women, 3074 attended follow-up examination (up to 32 months after enrollment). Cervical samples were obtained for liquid-based cytology and HPV DNA testing using Hybrid Capture 2 and Inno-Lipa Extra II. Information on lifestyle factors was collected through a personal interview. The probability of HR HPV persistence at a given time point since enrollment was estimated non-parametrically using the EMICM algorithm. RESULTS: Among the 462 women HR HPV positive at enrollment, 158 had at least one identical type detected at follow-up. The probability of persistence at 18 months after enrollment was 34.2 (95% CI 29.0-39.4). Stratifying by HIV status, the persistence probability was 42.9% (95% CI 33.5-51.9) among HIV positive, and 28.0% (95% CI 22.1-34.2) among HIV negative. Overall, HR HPV persistence was most common for HPV58, 35, 16, 31, and 52. Among HIV positive women it was HPV45, and HPV16, followed by HPV58 and HPV18, and among HIV negative women it was HPV31, HPV33 and HPV58. Risk factors associated with persistence of HR HPV were older age, longer interval between enrollment and follow-up, binge drinking, and HIV status. CONCLUSIONS: HR HPV persistence was common in Tanzania, and most common among HIV positive women. Overall, persistence was most frequent for HPV 58, 35, 16, 31 and 52. The nonavalent HPV vaccine should be considered.

RESUMO

Background: There is a substantial mental health treatment gap globally. Increasingly, mental health treatments with evidence of effectiveness in western countries have been adapted and tested in culturally and contextually distinct countries. Findings from these studies have been promising, but to better understand treatment outcome results and consider broader scale up, treatment acceptability needs to be assessed and better understood. This mixed methods study aimed to examine child and guardian acceptability of trauma-focused cognitive behavioral therapy (TF-CBT) in two regions in Tanzania and Kenya and to better understand how TF-CBT was perceived as helpful for children and guardians. Methods: Participants were 315 children (7-13), who experienced the death of one or both parents and 315 guardians, both of whom participated in TF-CBT as part of a randomized controlled trial conducted in Tanzania and Kenya. The study used mixed methods, with quantitative evaluation from guardian perspective (N=315) using the Treatment Acceptability Questionnaire (TAQ) and the Client Satisfaction Questionnaire-8 (CSQ-8). Acceptability was assessed qualitatively from both guardian and child perspectives. Qualitative evaluation involved analysis using stratified selection to identify 160 child and 160 guardian interviews, to allow exploration of potential differences in acceptability by country, setting (urban/rural), and youth age (younger/older). Results: Guardians reported high acceptability on the TAQ and, using an interpretation guide from U.S.-based work, medium acceptability on the CSQ-8. Guardians and children noted high acceptability in the qualitative analysis, noting benefits that correspond to TF-CBT's therapeutic goals. Analyses exploring differences in acceptability yielded few differences by setting or child age but suggested some potential differences by country. Conclusion: Quantitative and qualitative data converged to suggest high acceptability of TF-CBT from guardian and child perspectives in Tanzania and Kenya. Findings add to accumulating evidence of high TF-CBT acceptability from Zambia and other countries (United States, Norway, Australia).Plain Language Summary: Evidence-based treatments have been shown to be effective in countries and regions that are contextually and culturally distinct from where they were developed. But, perspectives of consumers on these treatments have not been assessed regularly or thoroughly. We used open-ended questions and rating scales to assess guardian and youth perspectives on a group-based, cognitive behavioral treatment for children impacted by parental death, in regions within Tanzania and Kenya. Our findings indicate that both guardians and youth found the treatment to be very acceptable. Nearly all guardians talked about specific benefits for the child, followed by benefits for the family and themselves. Eighty percent of youth mentioned benefits for themselves and all youth said they would recommend the program to others. Benefits mentioned by guardians and youth corresponded to treatment goals (improved mood/feelings or behavior, less distress when thinking about the parent/s' death). Both guardians and children named specific aspects of the treatment that they liked and found useful. Dislikes and challenges of the treatment were less frequently mentioned, but point to areas where acceptability could be further improved. Recommendations from participants also offer areas where acceptability could be improved, namely guardians' recommendation that the treatment also address non-mental health needs and offer some follow-up or opportunity to participate in the program again. Our study provides an example of how to assess acceptability and identify places to further enhance acceptability.

RESUMO

BACKGROUND: The causative role of human papillomavirus (HPV) in cervical carcinogenesis is well established; however, prospective studies examining high-risk(HR)-HPV acquisition among adult women in HIV-prevalent settings are limited. METHODS: We conducted a prospective study among women (25-60 years) attending cervical cancer screening in Tanzania. Cervical specimens obtained at enrolment and follow-up were tested for HPV. Participants were interviewed on lifestyle and tested for HIV. RESULTS: Among 3805 eligible women, 3074 (80.8%) attended follow-up (median time between the 2 examinations, 17.3 months); 307 had missing HPV results at enrolment or follow-up, leaving 2767 study participants. Among 2253 women initially HR-HPV negative, 184 acquired HR-HPV-incidence: 54.5 per 1000 person-years (95% CI:47.1-62.9); among HIV-positive women 75.2 per 1000 person-years (95% CI:54.5-103.7), HIV-negative 50.9 per 1000 person-years (95% CI:43.3-60.0). HPV52 and HPV16 were the most frequently acquired types. In multivariable regression analysis, HIV positivity, low CD4 count, younger age, and multiple sexual partners were associated with increased odds of HPV acquisition. CONCLUSION: HPV acquisition was higher among HIV-positive than HIV-negative women, especially women with low CD4 counts. Improvement of immune status among HIV-positives may decrease HPV acquisition. Nonavalent HPV vaccination should be considered given the pattern of HR-HPV types acquired.

RESUMO

INTRODUCTION: Adequate sexual and reproductive health information is vital to women of reproductive age (WRA) 15 to 49 years, for making informed choices on their reproductive health including family planning (FP). However, many women who interact with the health system continue to miss out this vital service. The study aimed to identify the extent of provision of FP counselling at service delivery points and associated behavioral factors among women of reproductive age in two districts of Arusha region. It also determined the association between receipt of FP counselling and contraceptive usage. METHODS: Data were drawn from a cross-sectional survey of 5,208 WRA residing in two districts of Arusha region in Tanzania; conducted between January and May 2018. Multistage sampling technique was employed to select the WRA for the face-to-face interviews. FP counseling was defined as receipt of FP information by a woman during any visit at the health facility for antenatal care (ANC), or for post-natal care (PNC). Analyses on receipt of FP counseling were done on 3,116 WRA, aged 16-44 years who were in contact with health facilities in the past two years. A modified Poisson regression model was used to determine the Prevalence Ratio (PR) as a measure of association between receipt of any FP counseling and current use of modern contraception, controlling for potential confounders. RESULTS: Among the women that visited the health facility for any health-related visit in the past two years, 1,256 (40%) reported that they received FP counselling. Among the women who had had births in the last 30 months; 1,389 and 1,409 women had contact with the service delivery points for ANC and PNC visits respectively. Of these 31% and 26% had a missed FP counseling at ANC and PNC visit respectively. Women who were not formally employed were more likely to receive FP counselling during facility visit than others. WRA who received any FP counseling at PNC were significantly more likely to report current use of modern contraception than those who did not (adjusted PR [adj. PR] = 1.28; 95% Confidence Interval [CI]: 1.09, 1.49). CONCLUSION: Overall, only 40% women reported that they received any form of FP counseling when they interfaced with the healthcare system in the past two years. Informally employed women were more likely to receive FP counselling, and women who received FP counselling during PNC visits were significantly more likely to use contraceptive in comparison to the women who did not receive FP counselling. This presents a missed opportunity for prevention of unintended pregnancies and suggests a need for further integration of FP counseling into the ANC and PNC visits.

RESUMO

PURPOSE: Cervical cancer screening is one of the strategies to prevent the disease among women at risk. Human papillomavirus (HPV) DNA testing is increasingly used as the cervical cancer screening method because of its high sensitivity. Self-collection of cervical specimens has the potential to improve participation. However, there is only limited information on comparison between self-collected and provider-collected samples with regard to detection of high-risk HPV using the careHPV method. The study aimed to compare HPV detection by careHPV in self-collected and provider-collected cervical samples and to assess the acceptability of self-collection techniques. MATERIAL AND METHODS: Women attending cervical cancer screening clinics at Ocean Road Cancer Institute, Kilimanjaro Christian Medical Centre or Mawenzi Hospital in Tanzania were included in the study. They underwent a face-to-face interview, HIV testing, and collected a self-sample using Evalyn Brush. Subsequently, they had a cervical sample taken by a health provider. Both samples were tested for high-risk HPV DNA using careHPV. RESULTS: Overall, 464 women participated in the study. The high-risk HPV prevalence was 19.0% (95% CI, 15.6 to 22.9) in the health provider samples, but lower (13.8%; 95% CI, 10.9 to 17.3) in the self-collected samples. There was a good overall agreement 90.5% (95% CI, 87.5 to 93.0) and concordance (κ = 0.66; 95% CI, 0.56 to 0.75) between the two sets of samples. Sensitivity and specificity were 61.4% (95% CI, 50.4 to 71.6) and 97.3% (95% CI, 95.2 to 98.7), respectively, varying with age. Most women preferred self-collection (79.8%). CONCLUSION: Overall, self-sampling seems to be a reliable alternative to health-provider collection and is acceptable to the majority of women. However, instructions on proper procedures for sample collection to the women are important.

RESUMO

BACKGROUND: Postpartum contraceptive discontinuation refers to cessation of use following initiation after delivery within 1 year postpartum. Discontinuation of use has been associated with an increased unmet need for family planning that leads to high numbers of unwanted pregnancies, unsafe abortion or mistimed births. There is scant information about contraceptive discontinuation and its predictors among postpartum women in Tanzania. This study aimed to determine predictors of contraception discontinuation at 3, 6, 12 months postpartum among women of reproductive age in Arusha city and Meru district, Tanzania. METHODS: This was an analytical cross-sectional study which was conducted in two district of Arusha region (Arusha city and Meru district respectively). A multistage sampling technique was used to select 13 streets of the 3 wards in Arusha City and 2 wards in Meru District. A total of 474 women of reproductive age (WRAs) aged 16-44 years residing in the study areas were included in this analysis. Data analysis was performed using STATA version 15. Odds ratios (ORs) with 95% confidence interval (CI) for the factors associated with contraceptives discontinuation (at 3, 6 and 12 moths) were estimated in a multivariable logistic regression model. RESULTS: Overall, discontinuation rate for all methods at 3, 6, and 12 months postpartum was 11, 19 and 29% respectively. It was higher at 12 months for Lactational amenorrhea, male condoms and injectables (76, 50.5 and 36%, respectively). Women aged 40-44 years had lower odds of contraceptive discontinuation at 3 months as compare to those aged 16 to 19 years. Implants and pills users had also lower odds of contraceptive discontinuation compared to injectable users at 3, 6 and 12 months respectively. CONCLUSION: Lactational amenorrhea, male condoms and injectables users had the highest rates of discontinuation. Women's age and type of method discontinued were independently associated with postpartum contraceptive discontinuation. Addressing barriers to continue contraceptive use amongst younger women and knowledge on method attributes, including possible side-effects and how to manage complications is warranted.

RESUMO

INTRODUCTION: Visual inspection of the cervix with acetic acid is used to control the burden of cervical cancer in low- and middle-income countries. This method has some limitations and HPV DNA testing may be an alternative, but it is expensive and requires a laboratory setup. Cheaper and faster HPV tests have been developed. This study describe the agreement between a fast HPV test (careHPV) and hybrid capture 2 (HC2) in detection of high-risk HPV among Tanzanian women. MATERIAL AND METHODS: The study involved women attending routine cervical cancer screening at the Ocean Road Cancer Institute and Kilimanjaro Christian Medical Centre in Tanzania. The women were offered HIV testing. Two cervical samples were subsequently obtained; the first sample was processed at the clinics using careHPV and the second sample was transported to Denmark and Germany for cytology and HC2 analysis. Kappa statistic was calculated to assess the agreement between careHPV and HC2. The sensitivity, specificity and predictive values of careHPV were calculated using HC2 as reference. The analyses were done for the overall study population and stratified by testing site and HIV status. RESULTS: A total of 4080 women were enrolled, with 437 being excluded due to invalid information, lack of careHPV or HC2 results. Overall agreement between the tests was substantial with a kappa value of 0.69 (95% confidence interval [CI] 0.66-0.72). The sensitivity and specificity of careHPV was 90.7% (95% CI 89.6-91.8) and 84.2% (95% CI 81.2-86.8), respectively. The agreement was similar in the stratified analyses where the kappa values were 0.75 (95% CI 0.70-0.79) in women aged 25-34, 0.66 (95% CI 0.62-0.70) in women aged 35-60, 0.73 (95% CI 0.70-0.77) at the Ocean Road Cancer Institute, 0.64 (95% CI 0.60-0.69) at the Kilimanjaro Christian Medical Center, 0.73 (95% CI 0.68-0.79) in HIV-positive and 0.66 (95% CI 0.63-0.70) in HIV-negative women. The kappa value of 0.64 (95% CI 0.39-0.88) for cervical high-grade lesions indicates a substantial agreement between careHPV and HC2 in detecting HPV among women with cervical high-grade lesions. CONCLUSIONS: A substantial agreement was found between careHPV and HC2 in detecting HPV overall as well as detecting HPV among women with cervical high-grade lesions. However, given the limited resources available in low and middle-income countries, the HPV testing assay should be weighed against the cost-effectiveness of the test.

RESUMO

INTRODUCTION: Human papillomavirus (HPV) is the causative agent of precancerous lesions and cervical cancer, cervical cancer being the leading cause of deaths in Tanzanian women. Early detection and treatment of precancerous lesions are important in the prevention of cervical cancer cases. MATERIAL AND METHODS: We conducted a cross-sectional study among 3390 Tanzanian women aged 25-60 years. Information on lifestyle habits was collected, and women underwent gynecological examination with collection of cervical cells for conventional cytological and HPV testing. Blood samples were tested for HIV. The association between cervical high-grade cytology (HGC) and potential risk factors was examined using multivariable logistic regression adjusting for age and high-risk HPV (HR-HPV). RESULTS: The prevalence of HGC was 3.6% and of low-grade cytology was 8.3%. In women who were both HR-HPV-positive and HIV-positive, the prevalence of HGC was 28.3%. It increased by age and was 47% among women aged 50-60 years. Women, who had their sexual debut at age 9-15 years and 16-18 years, respectively, had 2.5 and 2.4 times increased odds of HGC compared with women whose sexual debut was at age 21 years and older. HIV-positive women had increased odds of HGC in comparison with HIV-negative women after adjustment for age (odds ratio [OR] 2.95, 95% CI 1.92-4.54). HR-HPV-positive women had nearly 100-fold increased odds of HGC compared with HR-HPV-negative women (OR 96.6, 95% CI 48.0-194), and this estimate was higher among HIV-positive women (OR 152.2, 95% CI 36.1-642.0). CONCLUSIONS: Increasing age, early age at first intercourse, HR-HPV, and HIV infections were associated with a substantially increased risk of HGC.

RESUMO

INTRODUCTION: Exposure to intimate partner violence (IPV) has been found to be associated with a multitude of poor health and quality of life outcomes. Among the risks exacerbated by IPV is prenatal depression. Resilience is hypothesized to protect against psychopathology after exposure to a traumatic influence. The present study aims to investigate resilience as a moderator of the effect of exposure to IPV on prenatal depression among pregnant women in Moshi, Tanzania. MATERIAL AND METHODS: In this cross-sectional study, nested within a larger longitudinal study, pregnant women receiving antenatal care were interviewed about exposure to IPV, signs of depression using the Edinburgh Postpartum Depression Scale, and resilience using the abbreviated Connor-Davidson Resilience Scale. Logistic regression was used to test the effect of the interaction term of resilience and exposure to IPV during pregnancy on the risk of high level of signs of depression. RESULTS: In total, 1013 women completed all interviews, 300 women reported exposure to IPV, and 113 had high levels of signs of depression. Mean resilience score was 14.26 (SD 9.45). Exposure to IPV was correlated with signs of depression (adjusted odds ratio 6.49, 95% CI 3.75-11.24). Resilience was not correlated with signs of depression, nor was the interaction term of resilience and exposure to IPV. CONCLUSIONS: The study did not find that resilience acted as a moderator of the effect of exposure to IPV during pregnancy on the risk of prenatal depression. The cross-sectional design of the study may not be well suited to investigate resilience, which could take time to manifest. The abbreviated Connor-Davidson Resilience Scale has not been validated in a Tanzanian setting, or in the Swahili version. Practitioners should take note that all women and families affected by IPV should be afforded relevant assistance from social services, law enforcement, healthcare practitioners, and other relevant services, regardless of their apparent level of resilience.
