RESUMEN

COVID-19 vaccination effectively reduces disease severity, hospitalization, and mortality, particularly among individuals with chronic conditions who bear a disproportionate burden of disease complications. Vaccine confidence - belief in its safety, effectiveness, and importance - boosts uptake. However, limited data on vaccine confidence in this population hinders the development of targeted interventions. This study examined COVID-19 vaccine confidence and its impact on uptake among individuals with hypertension or diabetes mellitus in the Kilimanjaro region, Tanzania. A community-based cross-sectional study was conducted in March 2023 among 646 randomly selected adults aged ≥18 years with hypertension or diabetes mellitus in three districts of Kilimanjaro region, northern Tanzania. An interviewer-administered electronic questionnaire assessed confidence and uptake of COVID-19 vaccines in addition to related knowledge and demographic characteristics. Data analysis was done for 646 individuals who consented to participate. Multivariable logistic regression models determined the factors associated with COVID-19 vaccine confidence and its effect on vaccine uptake. The proportion of COVID-19 vaccine confidence among all 646 participants was 70% and was highest for perceived vaccine importance (80%), followed by perceived vaccine effectiveness (77%) and perceived vaccine safety (74%). Good knowledge of COVID-19 vaccines and living in the Mwanga municipal council (MC), a semi-urban district, was independently associated with confidence in the vaccines' importance, safety, effectiveness, and overall COVID-19 vaccine confidence. Confidence in COVID-19 vaccines increased the odds of vaccine uptake. Targeted interventions to boost vaccine confidence are therefore essential to enhance vaccine uptake in this high-risk population.

RESUMEN

Background: Schistosomiasis is an acute and chronic tropical disease caused by trematodes of the genus Schistosoma. It is a disease of public health concern and mostly affects developing countries of the tropics. According to WHO burden of the disease is as high as 80-85%, principally in sub-Saharan Africa. Although the majority of the infection is often linked with morbidity, it also results in considerable death. The overall annual mortality rate might exceed 200,000 people in Africa due to different complications of urinary and intestinal Schistosomiasis. Children are at a greater risk of acquiring the infection as well as reinfection, and this might cause growth retardation, anemia and low school performance. Objective: The study aimed at determining the prevalence of Schistosoma mansoni, associated factors and evaluating the performance of Point of Care Circulating Cathodic Antigen comparison (POC-CCA) against a routine method (formal Ether) of detection methods among school aged children at Mwanga District Council, Kilimanjaro Tanzania. Methodology: This was a cross sectional study conducted from April - June 2019 in Mwanga District Council. A minimum of 288 primary school children in Mwanga District were enrolled. Random sampling technique was used to select the participants. Interviews were conducted with study participants followed by single stool and urine sample collection. formal-ether concentration technique, urine dipstick and Point of Care Circulating Cathodic Antigen (POC-CCA) were used for stool and urine analysis. Data were entered and cleaned by using SPSS Version 20. Descriptive statistics were summarised using frequency and proportion for categorical variables and mean and standard dispersion for continuous variables. Logistic regression was used to identify independent factors associated with schistosomiasis. Any association with P value <.05 was considered significant. Results: A total of 288 participants were enrolled. The mean age of participants was 9.8 (±2.4) years. The prevalence of Schistosoma mansoni among the 288 students was 7.3% by formal ether method and 80.4% by POC-CCA. Social demographic characteristics, and hygiene practice assessed were not associated with Schistosoma mansoni in this study. Water source was statistically significantly associated with the prevalence of Schistosoma mansoni. Conclusion: The prevalence of Schistosoma mansoni among school aged children is low by using formal-ether concentration technique (routine method). The annual projects of deworming might have helped decrease the endemicity of the infection. This is due to regular deworming project as recommended by WHO. Despite various efforts which are done to deworm, school aged children are still at risk of acquiring infection, due to poor hygienic practice especially from water sources.

RESUMEN

Introduction: postnatal care (PNC) is critical for the health and survival of the mother and the newborn. The timing of the first postnatal checkup is crucial for the early identification and treatment of complications. Late or zero attendance of postnatal checkups negatively influences the health of the mother and the newborn. The study's purpose is to determine the prevalence and factors associated with early postnatal care utilization among women of reproductive age (WRA) in Tanzania. Methods: this is an analytical cross-sectional study, using Tanzania demographic health survey data for 2015/16. Women of reproductive age (15-49 years) who gave birth 5 years prior the survey were analyzed. Data analysis was performed using Stata software Version 15. The Poisson regression analysis was used to assess factors associated with early PNC. Results: the prevalence of early PNC utilization in Tanzania was 36%. The identified determinants for early PNC were geographical zone, place of residence, access to media, place of delivery and mode of delivery. The prevalence of early PNC was higher among mothers with access to media, with caesarian delivery and to those with facility delivery. The prevalence was low among mothers who lived in rural areas, from southwest and lake zones. Conclusion: the coverage of early PNC was found to be low in Tanzania. Interventions informed by the identified factors need to be designed and implemented to improve the coverage of early PNC.

RESUMEN

BACKGROUND: Family interactions, which are always multi-faceted, are complicated further by family members with disabilities. In resource-poor settings, policies and programmes that address the needs of and challenges faced by families are often inaccessible or unavailable. Approximately 13% of the families in Tanzania have at least one member with a disability, yet family-centred research on caring for disabled children and adolescents is scarce in this context. OBJECTIVE: The aim is to explore the needs and challenges faced by families that care for children and adolescents with physical disabilities in the Kilimanjaro Region of north-eastern Tanzania. METHODS: This qualitative study had a constructivist grounded-theory design. In-depth interviews, using a semi-structured interview guide based on the social-capital framework, were conducted with 12 female participants aged between 24 and 80. A conceptual model of family needs, inspired by Maslow's hierarchy of needs, informed the analysis. RESULTS: Challenging needs were grouped into five categories, which were linked to Maslow's hierarchy of needs and related to the central concept of 'adaptive adjustment': (1) 'barely surviving'; (2) 'safety needs in jeopardy'; (3) 'sociocultural protection'; (4) 'self-esteem far beyond reach', and (5) 'dreaming of self-actualisation'. CONCLUSION: Families caring for children and adolescents with physical disabilities in north-eastern Tanzania have needs that extend beyond the available and accessible resources. Families can adjust and adapt by avoiding certain situations, accepting the reality of their circumstances and exploring alternative ways of coping. A sustainable support system, including social networks, is essential for meeting basic needs and ensuring safety.


Main findings: The challenges associated with caring for children and adolescents with disabilities are related to various environmental and social barriers, any of which can significantly impact the wellbeing of all family members.Added knowledge: In the context of a study conducted in north-eastern Tanzania, both nuclear and extended family networks were found to be valuable sources of support for these families.Global health impact for policy and action: Families must take considerable steps to strengthen their sociocultural support systems while, the support of the government and other stakeholders is crucial in addressing the challenges faced by families caring for children and adolescents with disabilities.

RESUMEN

Introduction: Pneumococcal conjugate vaccines have reduced severe disease attributed to vaccine-type pneumococci in children. However, the effect is dependent on serotype distribution in the population and disease development may be influenced by co-occurrence of viral and bacterial pathogens in the nasopharynx. Methods: Following introduction of the 13-valent pneumococcal conjugate vaccine (PCV13) in Tanzania we performed repeated cross-sectional surveys, including 775 children below 2 years of age attending primary healthcare centers. All children were sampled from nasopharynx and pneumococci were detected by single-target PCR. Pneumococcal serotypes/groups and presence of viruses and other bacteria were determined by two multiplex PCR assays. Results: The prevalence of PCV13 vaccine-type pneumococci decreased by 50%, but residual vaccine-types were still detected in 21% of the children 2 years after PCV13 introduction. An increase in the non-vaccine-type 15 BC was observed. Pneumococci were often co-occurring with Haemophilus influenzae, and detection of rhino/enterovirus was associated with higher pneumococcal load. Discussion: We conclude that presence of residual vaccine-type and emerging non-vaccine-type pneumococci in Tanzanian children demand continued pneumococcal surveillance. High co-occurrence of viral and bacterial pathogens may contribute to the disease burden and indicate the need of multiple public health interventions to improve child health in Tanzania.

RESUMEN

Background: Tanzania is one of the countries with a high burden of HIV. It has an estimated 1.4 million people living with HIV in 2021. Adolescents living with HIV on antiretroviral therapy (ART) have worse treatment adherence, viral suppression, and mortality rates compared to adults. This study aim was to determine the trend of non-suppression among adolescents on ART in Tanzania from 2018 to 2021 and latest associated predictors. Methodology: The study utilized data of adolescents (10-19 years) receiving ART in Tanzania mainland for the period of 2018-2021 from the National Care and Treatment Centers database. The primary outcome of interest was non-suppression of viral load, defined as a VL above 1,000 copies/ml. The study employed multivariable logistic regression models to identify factors associated with non-suppression of VL. STATA 15 statistical software was used to analyze the data. Results: Records of 65,942 adolescents present in the CTC database Tanzania were analyzed. Approximately more than half were female 38,544 (58.5%). The proportion of non-suppression was 34.5%, 23.3%, 12.1%, and 9.7% for the years 2018-2021, respectively. After adjusting for other factors, adolescents with a history of poor adherence to ART in the last six months had higher odds of non-suppression (OR = 1.95, 95% CI = 1.64, 2.31). Adolescents on second or third line ART regimens were almost two times more likely to be non-suppressed compared to those on first-line regimens (OR = 2.85, 95% CI = 2.52, 3.23). Girls had lower odds of non-suppression compared to boys (OR = 0.91, 95% CI = 0.84, 0.98), and similarly, patients attending hospitals had lower odds compared to those attending dispensaries (OR = 0.79, 95% CI = 0.72, 0.87). Conclusion: Being female, having good history of adherence over the last six months, and attending hospital level was significantly associated with lower levels of non-suppression, while being on second line ART or attending lower health facilities increased the odds of non-suppression. Efforts to enhance the quality and capacity of health services at lower-level facilities (dispensaries and health centers) should be prioritized, as well as promoting gender-sensitive approaches that take into account the unique needs and experiences of adolescent girls and boys are needed to improve VL suppression among this population.

RESUMEN

The 'urban penalty' in health refers to the loss of a presumed survival advantage due to adverse consequences of urban life. This study investigated the levels and trends in neonatal, post-neonatal and under-5 mortality rate and key determinants of child survival using data from Tanzania Demographic and Health Surveys (TDHS) (2004/05, 2010 and 2015/16), AIDS Indicator Survey (AIS), Malaria Indicator survey (MIS) and health facility data in Tanzania mainland. We compared Dar es Salaam results with other urban and rural areas in Tanzania mainland, and between the poorest and richest wealth tertiles within Dar es Salaam. Under-5 mortality declined by 41% between TDHS 2004/05 and 2015/2016 from 132 to 78 deaths per 1000 live births, with a greater decline in rural areas compared to Dar es Salaam and other urban areas. Neonatal mortality rate was consistently higher in Dar es Salaam during the same period, with the widest gap (> 50%) between Dar es Salaam and rural areas in TDHS 2015/2016. Coverage of maternal, new-born and child health interventions as well as living conditions were generally better in Dar es Salaam than elsewhere. Within the city, neonatal mortality was 63 and 44 per 1000 live births in the poorest 33% and richest 33%, respectively. The poorest had higher rates of stunting, more overcrowding, inadequate sanitation and lower coverage of institutional deliveries and C-section rate, compared to richest tertile. Children in Dar es Salaam do not have improved survival chances compared to rural children, despite better living conditions and higher coverage of essential health interventions. This urban penalty is higher among children of the poorest households which could only partly be explained by the available indicators of coverage of services and living conditions. Further research is urgently needed to understand the reasons for the urban penalty, including quality of care, health behaviours and environmental conditions.

RESUMEN

BACKGROUND: Globally, the number of small-scale miners (SSM) is estimated to be more than 25 million, but it supports the livelihoods of around 100 million individuals. In Tanzania, the number of SSM has increased from an estimated 150,000 in 1987 to ~1.5 million in 2017. The miners are at a high risk of occupational-related health challenges. The study aimed to assess the concentrations of respirable crystalline silica (RCS) and radon among the tanzanite mining communities in Simanjiro District, Tanzania. METHODS: We carried out a cross-sectional study involving the Mererani mines in Tanzania. These are underground mines comprised of informally employed miners, i.e. SSM. Concentrations of RCS and radon gas were measured in 44 study units, i.e. 22 mining pits and within 22 houses in the general community, e.g. shops in the peri-mining community. A total of 132 respirable personal dust exposure samples (PDS), 3 from each of the study units were taken, but only 66 PDS from the mining pits were analysed, as this was the main interest of this study. Radon concentration was measured by continuous monitoring throughout the working shift (and overnight for residences) using AlphaGuard monitor. The medians and comparison to the reference values, OSHA USA PEL and WHO/IARC references, were done for RCS and radon, respectively, using SPSS Ver. 27.0.0). RESULTS: The median time-weighted average (TWA) concentration of the RCS in the mining pits was 1.23 mg/m3. Of all 66 personal dust samples from the mining pits, 65 (98.5%) had concentrations of RCS above the Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) of 0.05 mg/m3. Mining pits had a median radon concentration of 169.50 bq/m3, which is above the World Health Organization (WHO)/International Commission on Radiation Protection (ICRP) recommended reference of 100.00 bq/m3 but not above the upper reference of 300.00 bq/m3, while the community buildings had a median radon concentration of 88.00 bq/m3. Overall, 9 (20.5%) and 17 (38.6%) radon measurements were above 300.00 bq/m3 and between 100.00 and 300.00 bq/m3 references, respectively. Specifically, in the mining pits, 9 (40.9%) test results were above 300.00 bq/m3, while none of the test results in the community was above 300.00 bq/m3. CONCLUSION: The tanzanite SSM in Mererani we highly exposed to RCS, which increases the risk of pulmonary diseases, including silicosis, tuberculosis, and pulmonary malignancies. Immediate action by OSHA Tanzania should be enforcement of wearing respirators by all miners throughout the working hours. Health education programmes to the SSM must be strengthened and OSHA Tanzania should adopt the 0.05 mg/m3 PEL, and enforce other occupational health and safety measures, including regular use of dust suppression mechanisms (water spray and wet drilling) and monitoring of RCS exposures among SSM. Monitoring of radon exposure both in the mining pits and community buildings should be conducted, and mitigation measures should be implemented in areas that exceed the reference level of 100.00 bq/m3.

RESUMEN

BACKGROUND: Routine health facility data provides the opportunity to monitor progress in quality and uptake of health care continuously. Our study aimed to assess the reliability and usefulness of emergency obstetric care data including temporal and regional variations over the past five years in Tanzania Mainland. METHODS: Data were compiled from the routine monthly district reports compiled as part of the health management information systems for 2016-2020. Key indicators for maternal and neonatal care coverage, emergency obstetric and neonatal complications, and interventions indicators were computed. Assessment on reliability and consistency of reports was conducted and compared with annual rates and proportions over time, across the 26 regions in of Tanzania Mainland and by institutional delivery coverage. RESULTS: Facility reporting was near complete with 98% in 2018-2020. Estimated population coverage of institutional births increased by 10% points from 71.2% to 2016 to 81.7% in 2020 in Tanzania Mainland, driven by increased use of dispensaries and health centres compared to hospitals. This trend was more pronounced in regions with lower institutional birth rates. The Caesarean section rate remained stable at around 10% of institutional births. Trends in the occurrence of complications such as antepartum haemorrhage, premature rupture of membranes, pre-eclampsia, eclampsia or post-partum bleeding were consistent over time but at low levels (1% of institutional births). Prophylactic uterotonics were provided to nearly all births while curative uterotonics were reported to be used in less than 10% of post-partum bleeding and retained placenta cases. CONCLUSION: Our results show a mixed picture in terms of usefulness of the District Health Information System(DHIS2) data. Key indicators of institutional delivery and Caesarean section rates were plausible and provide useful information on regional disparities and trends. However, obstetric complications and several interventions were underreported thus diminishing the usefulness of these data for monitoring. Further research is needed on why complications and interventions to address them are not documented reliably.

RESUMEN

BACKGROUND: HIV Testing and Counseling is a critical entry-point for HIV care, treatment and prevention. Tanzania adopted the WHO recommendations of Provider-Initiated HIV Testing and Counseling (PITC) in 2007 with the aim of increasing early HIV diagnosis and timely access to treatment and support services. However, approximately 55% of men are still unaware of their HIV status. This study aimed to determine the level of PITC uptake and factors associated with PITC availability and uptake among men attending healthcare facilities in Moshi Municipality, Northern Tanzania. METHOD: A facility-based cross-sectional study was conducted in July 2019 in five selected healthcare facilities in Moshi Municipal, Kilimanjaro region. Exit interviews were conducted with men aged 18 years and above who attended for care in the selected facilities. Modified Poisson regression modelling with robust standard errors were used to determine factors independently associated with being offered and accepting the PITC offer. RESULTS: A total of 562 men participated in this study. The median age of participants at enrollment was 37 (IQR: 26-59) years. Only 58% of participants reported to have been offered provider-initiated HIV counseling. Of these, 83% accepted the offer of HIV testing. Age between 35-59 years (aPR = 1.2; 95% Confidence Interval (CI): 1.0, 1.4; p = 0.033) and having primary education (aPR = 0.7; 95% CI: 0.6, 0.9; p = 0.010) were factors independently associated with being offered PITC. Age between 35-59 years (aPR = 0.8; 95% CI: 0.7, 0.9; p = 0.002); having been previously tested for HIV (aPR = 1.3; 95% CI: 1.1, 1.5; p = 0.011) and visiting a health facility twice or more in previous year (aPR = 1.3; 95% CI: 1.2, 1.5; p<0.001) were independently associated with uptake of HIV testing. CONCLUSION: Despite high PITC uptake, about 2 in 5 men attending healthcare facilities in Moshi municipality were not offered the service. Providers should target men aged ≤ 34 years, with primary education, visiting facilities for the first time and who have never been tested for HIV.

RESUMEN

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.

RESUMEN

Background: Low uptake of modern contraceptives among adolescents remains a serious public health concern with over 20 million adolescents in need of modern contraceptives are not using any. In Tanzania where the adolescent fertility rate is 112 per 1000, only 15.2% of adolescents are using modern contraceptives. Contraceptive use stands out to be one of the key interventions to reduce the burden of adolescent pregnancy which is high in the country at 22%. There is little information on factors associated with modern contraceptive use among out of school adolescents, who are at an increased risk of adolescent pregnancies. Objective: To determine the prevalence and factors associated with modern contraceptive use among out of school adolescent girls in Moshi municipality, Kilimanjaro region. Methodology: This was a population based cross-sectional study, conducted in Moshi municipality in Kilimanjaro region 2 wards; Majengo and Njoro. The wards were randomly selected out of the 21 wards in the region. Household survey was conducted in the wards and adolescents aged 10 to 19 years who were out of school and consented and or assented to participate in the study were recruited. Data was collected using Kobo Collect TM on an Android device. Data was analysed using SPSS version 20. To determine the factors associated with modern contraceptive use, crude and adjusted analysis using logistic regression analysis was done. Results: A total of 298 out-of-school adolescents were enrolled, with a median age of 19 (IQR 17-19) years. The prevalence of ever use of modern contraceptives among 154 sexually active adolescents was 51%, and 35% were current users of the methods. Two of common methods ever used were; injectables (27.3%) and male condoms (3.2%) respectively. Factors independently associated with ever use of modern contraceptives were; being married or cohabiting (aOR: 5.7) and having 2 or more sexual partners in the past 12 months (aOR: 5.9). Conclusion: Ever and current use of modern contraceptives among out-of-school adolescents were reported at 51% and 35% respectively. Respondent's marital status and number of sexual partners was associated with ever use of modern methods. Strengthening of adolescent-friendly SRH services outside facility setting is needed given very few are currently using a modern method. Further, through inter-sectoral collaboration interventions to keep adolescent girls at school should be strengthened.

RESUMEN

Background: Adolescent pregnancy increases the risk of maternal and child morbidity and mortality. We aimed to determine trends and factors associated with adolescent pregnancy in Tanzania from 2004 to 2016 using the Tanzania Demographic and Health surveys (TDHS). Methods: We carried out an analytical cross-sectional study using the TDHS data for the years 2004 to 2005, 2010 and 2015 to 2016 among adolescent girls aged 15 to 19 years. Data analysis was performed using STATA version 15. Data analysis considered the complex survey design inherent in the demographic and health survey (DHS) data. The Poisson regression model was used to estimate Prevalence Ratios (PR) and 95% confidence intervals for factors associated with adolescent pregnancy. Results: We analysed data for a total of 10,972 adolescents for the three TDHS rounds. The proportion of adolescent pregnancy significantly decreased from 26% to 22.8% from the year 2004/05 to 2010 and then increased again to 26.7% in 2015/16. Adolescents who were aged 18 to 19 years (APR 1.52; 95% CI, 1.38 to 1.68) married or cohabiting with their partners (APR 2.15; 95% CI, 1.93 to 2.40; P<.001), widowed/divorced/separated (APR 2.32; 95% CI, 2.03 to 2.66; P<.001), and among those who started sexual activity before 15 years of age (APR 1.20; 95% CI, 1.11 to 1.31; P<.001) were more likely to become pregnant during adolescence. In contrast, adolescents with secondary school education level and above were the least likely to become pregnant (APR 0.62; 95% CI, 0.51 to 0.75; P<.001) compared to those with no formal education. Conclusion: One in four adolescent girls aged 15 to 19 in Tanzania have already started childbearing and despite fluctuation, high rate of adolescent pregnancy persists. Preventive interventions should focus on adolescents with low education level, married/cohabiting with their partners, and who have started sex before 15 years of age. We advocate for the increase of school attendance until high school level to reduce the risk of early pregnancy in adolescents. Furthermore, qualitative studies are crucial to explore reasons for the rising trend of adolescent pregnancy in most zones of Tanzania, particularly between 2010 and 2015/16.

RESUMEN

Vaccination is the most cost-effective way of preventing Coronavirus Disease 2019 (COVID-19) although there was a considerable delay in its institution in Tanzania. This study assessed health care workers' (HCWs) self-perceived infection risk and uptake of COVID-19 vaccines. A concurrent embedded, mixed methods design was utilized to collect data among HCWs in seven Tanzanian regions. Quantitative data was collected using a validated, pre-piloted, interviewer administered questionnaire whereas in-depth interviews (IDIs) and focus group discussions (FGDs) gathered qualitative data. Descriptive analyses were performed while chi-square test and logistic regression were used to test for associations across categories. Thematic analysis was used to analyze the qualitative data. A total of 1,368 HCWs responded to the quantitative tool, 26 participated in the IDIs and 74 in FGDs. About half of the HCW (53.6%) reported to have been vaccinated and three quarters (75.5%) self-perceived to be at a high risk of acquiring COVID-19 infection. High perceived infection risk was associated with increased COVID-19 vaccine uptake (OR 1.535). Participants perceived that the nature of their work and the working environment in the health facilities increased their infection risk. Limited availability and use of personal protective equipment (PPE) was reported to elevate the perceived infection risks. Participants in the oldest age group and from low and mid-level health care facilities had higher proportions with a high-risk perception of acquiring COVID-19 infection. Only about half of the HCWs reported to be vaccinated albeit the majority recounted higher perception of risk to contracting COVID-19 due to their working environment, including limited availability and use of PPE. Efforts to address heightened perceived-risks should include improving the working environment, availability of PPE and continue updating HCWs on the benefits of COVID-19 vaccine to limit their infection risks and consequent transmission to their patients and public.

RESUMEN

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.

RESUMEN

Tuberculosis (TB) is among diseases of global health importance with Sub Saharan Africa (SSA) accounting for 25% of the global TB burden. TB prevalence among miners in SSA is estimated at 3,000-7,000/100,000, which is about 3 to 10-times higher than in the general population. The study's objective was to determine the prevalence of TB and associated risk factors among mining communities in Mererani, northern Tanzania. This was a cross-sectional study conducted from April 2019 to November 2021 involving current Small Scale Miners (SSM) and the General Community (GC). A total of 660 participants, 330 SSM and 330 GC were evaluated for the presence of TB. Data were analysed using Statistical Package for the Social Sciences (SPSS) database (IBM SPSS Statistics Version 27.0.0.0). Binary logistic regression (Generalized Linear Mixed Model) was used to determine the association between TB and independent predictors. Prevalence of TB was 7%, about 24-times higher than the national prevalence of 0.295%. Participants from the general community had higher prevalence of TB 7.9% than SSM (6.1%). Both for SSM and the GC, TB was found to be associated with: lower education level (aOR = 3.62, 95%CI = 1.16-11.28), previous lung disease (aOR = 4.30, 95%CI = 1.48-12.53) and having symptoms of TB (aOR = 3.24, 95%CI = 1.38-7.64). Specifically for the SSM, TB was found to be associated with Human Immunodeficiency Virus (HIV) infection (aOR = 8.28, 95%CI = 1.21-56.66). Though significant progress has been attained in the control of the TB epidemic in Tanzania, still hot spots with significantly high burden of TB exists, including miners. More importantly, populations surrounding the mining areas, are equally affected, and needs more engagement in the control of TB so as to realize the Global End TB targets of 2035.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVES: To describe the characteristics and disability-related needs of children and adolescents with physical disabilities in the Kilimanjaro region, North-Eastern Tanzania. DESIGN: A cross-sectional community survey was conducted from November 2020 to June 2021. Trained research assistants interviewed primary children's carers using a questionnaire based on the International Classification of Functioning, Disability and Health-Children and Youth Framework. Data were analysed using IBM SPSS Statistics V.27. The Pearson χ2 test was used to examine differences between age, gender and self-reported needs. The independent t-test assessed difference in needs according to age and gender. SETTING: Kilimanjaro region, Tanzania. PARTICIPANTS: Children and adolescents, aged 2-18 years, with physical disabilities (n=212). RESULTS: Almost 40% had severe speech (n=84) and joint mobility (n=79) impairments, and more than half (n=124) had severe or complete difficulties walking. In aspects of self-care (caring for body parts, toileting, dressing, eating and drinking), most had severe and complete difficulties. Almost 70% (n=135) of households were located near health facilities without rehabilitation services. About one-quarter (n=51) had never received rehabilitation services. More than 90% (n=196) needed assistive devices, and therapeutic exercises (n=193). Over three-quarters needed nutritional supplements (n=162). CONCLUSION: Children and adolescents with physical disabilities in North-Eastern Tanzania have impaired speech and joint mobility, and difficulties in communication, self-care and walking. Rehabilitation services essential for addressing these impairments and activity limitations are either scarce or inaccessible. Action is needed to facilitate urban and rural access to rehabilitation services in order to improve the well-being of children and adolescents with physical disabilities.

RESUMEN

Introduction: Adolescent's living with Human Immunodeficiency Virus (HIV) are widely reported to have poor adherence to antiretroviral therapy (ART) due to stigma and fear of discrimination. A "Teen club" is an adolescent centered intervention designed to reduce social stigma and improve adherence and retention in HIV care. In this study we determined how the availability of teen clubs within routine HIV care and treatment facilities affects adolescents' clinic attendance. Methods: We conducted a retrospective cohort study using secondary data from routine clinic records on adolescents (10-19 years) who started ART between 2010 and 2016, and had documented clinic visits between March 2017 and September 2017 at HIV care and treatment clinics (CTC) in northern and central Tanzania. Good clinic attendance was defined as attending at least four monthly clinic visits during the 7-month follow-up period. A Poisson model with robust standard errors was used to assess the relationship between presence of a teen club at health facilities and good clinic attendance adjusting for other factors including sex, age at ART initiation, duration on ART, WHO clinical stage and health facility level. Results: Of the 2839 adolescents, 73.1% had good clinic attendance. Good clinic attendance was independently associated with availability of a teen club at the health facility (aRR=1.16, 95%CI:1.09-1.21) and been on ART for >2 years (aRR=1.15, 95%C1.02-1.30). Adolescents aged 15-19 years during this study were less likely to have good clinic attendance (aRR= 0.93, 95%CI:0.88-0.98) than those aged <15 years. Sex and WHO clinical stage were not associated with good clinic attendance. Conclusion: Teen clubs improved visit adherence among adolescents in HIV care and treatment. Further qualitative research should be conducted to explore adolescents' perception of teen clubs as well as other enablers to clinic attendance.
