Willingness to HPV self-sampling for cervical cancer screening and its predictors among women attending outpatient clinics in Meru District, Arusha Region, Northern Tanzania

Background: The ability for women to self-collect human papillomavirus (HPV) samples can potentially reduce the risk of cervical cancer and increase screening coverage. Objectives: To assess the willingness to HPV self-sampling for cervical cancer screening and its predictors among women attending outpatient clinics in Arusha region, northern Tanzania. Methods: A hospital-based cross-sectional study was conducted among 706 women aged 18-55 years in Meru District Hospital and Usa River Health Centre from March to April 2019. Face-to-face intervies were conducted using a questionnaire. Data analysis was performed using Stata version 14.0. The log-binomial regression was used to determine factors associated with willingness to self-collection of HPV samples. Results: Majority (70%) of the women were willing to self-collection of HPV samples for cervical cancer screening and was associated with attending Meru District hospital (PR=2.02, 95%CI 1.77-2.31); good knowledge about cervical cancer warning signs (PR=1.11, 95%CI 1.01-1.22), prevention (PR=1.13, 95%CI 1.04-1.20), and symptoms (PR=1.61, 95%CI 1.33-1.93); and having formal employment (PR=1.22, 95%CI 1.07-1.37). Conclusion: The majority of women were willing to self-collect HPV samples for cervical cancer screening. Self-collection is, therefore, an acceptable and viable means of screening for cervical cancer, which has great implications for Tanzania from a health policy perspective.

Risk factors for inappropriate blood requisition among hospitals in Tanzania.

BACKGROUND: Blood is a critical aspect of treatment in life saving situations, increasing demand. Blood requisition practices greatly effect sufficient supply in blood banks. This study aimed to determine the risk factors for inappropriate blood requisition in Tanzania. METHODS: This was a cross sectional study using secondary data of 14,460 patients' blood requests from 42 transfusion hospitals. Primary data were obtained by using cluster-sampling design. Data were analysed using a two-level mixed-effects Poisson regression to determine fixed-effects of individual-level factors and hospital level factors associated with inappropriate blood requests. P-value <0.05 (2-tails) was considered statistically significant. RESULTS: Inappropriate requisition was 28.8%. Factors significantly associated with inappropriate requisition were; reporting pulse rate and capillary refill decrease the risk (RR 0.74; 95% CI 0.64, 0.84) and (RR 0.73; 95% CI 0.63, 0.85) respectively and the following increased the risk; having surgery during hospital stay (RR 1.22; 95% CI 1.06, 1.4); being in general surgical ward (RR 3.3; 95% CI 2.7, 4.2), paediatric ward (RR 1.8; 95% CI 1.2, 2.7), obstetric ward (RR 2.5; 95% CI 2.0, 3.1), gynaecological ward (RR 2.1; 95% CI 1.5, 2.9), orthopaedics ward (RR 3.8; 95% CI 2.2, 6.7). Age of the patient, pallor and confirmation of pre-transfusion haemoglobin level were also significantly associated with inappropriate requisition. Majority of appropriate requisitions within the wards were marked in internal medicine (91.7%) and gynaecological wards (77.8%). CONCLUSIONS: The proportion of inappropriate blood requests was high. Blood requisition was determined by clinical and laboratory findings and the ward patients were admitted to. Adherence to transfusion guidelines is recommended to assure the best use of limited blood supply

Do Women Enrolled in PMTCT Understand the Recommendations: A Case Study from Kilimanjaro.

INTRODUCTION: Prevention of mother-to-child transmission (PMTCT) remains a cornerstone of HIV prevention and control efforts. It is vital that the beneficiaries of PMTCT programs understand PMTCT recommendations, especially since their adherence to recommendations is key to successful PMTCT. There have been several major changes in PMTCT recommendations, and many women have encountered different recommendations. It is plausible that confusion has arisen as to what is currently recommended for successful PMTCT. This confusion can affect adherence to recommendations and hinder PMTCT efforts. However, little is known about how women enrolled in PMTCT understand the recommendations in the context of these frequent changes. AIM: In this paper, we present our findings regarding how HIV-positive women enrolled in PMTCT in Kilimanjaro understand PMTCT recommendations pertinent to them. METHODS: From August 2019 to April 2020, we surveyed 521 mothers enrolled in PMTCT in seven districts in the Kilimanjaro region, Northern Tanzania. A pretested questionnaire was administered to consenting mothers. The questionnaire collected information on mothers' demographic characteristics, previous encounters with PMTCT, and knowledge of various PMTCT program elements, including medication duration, breastfeeding recommendations and infant HIV testing schedule. A logistic regression model was used to determine factors associated with good PMTCT knowledge among mothers. RESULTS: A total of 521 women were enrolled, the median score for the 19 items used to assess knowledge was 57.9%, and 64.9% scored above the median. Counselling on ART (OR=2.17, 95% CI 1.08-4.36) and counselling on breastfeeding during the ANC visits (OR=2.38, 95% CI 1.38-4.11) were the only factors that we found to be significantly associated with higher odds of good knowledge of PMTCT. CONCLUSION: Even amongst mothers enrolled in PMTCT, poor understanding regarding key PMTCT recommendations prevails. There is a need to reassess the training modalities and look at ways to reinforce PMTCT messages to mothers

Body mass index and risk of over 100 cancer forms and subtypes in 4.1 million individuals in Sweden : the Obesity and Disease Development Sweden (ODDS) pooled cohort study

Background: Obesity, assessed by body mass index (BMI), is an established risk factor for 13 cancers. We aimed to identify further potential obesity-related cancers and to quantify their association with BMI relative to that of established obesity-related cancers. Methods: Using Cox regression models on 4,142,349 individuals in Sweden (mean age 27.1 years at weight measurement), we calculated hazard ratios (HRs) for the association between BMI and the risk of 122 cancers and cancer subtypes, grouped by topography and morphology. Cancers with a positive association (i.e., HR >1) at an α-level of 0.05 for obesity (BMI ≥30 kg/m2) vs. normal weight (BMI 18.5–24.9 kg/m2) or per 5 kg/m2 higher BMI, for which obesity is not an established risk factor, were considered potentially obesity related. Findings: After 100.2 million person-years of follow-up, 332,501 incident cancer cases were recorded. We identified 15 cancers in men and 16 in women as potentially obesity related. These were cancers of the head and neck, gastrointestinal tract, malignant melanoma, genital organs, endocrine organs, connective tissue, and haematological malignancies. Among these, there was evidence of differential associations with BMI between subtypes of gastric cancer, small intestine cancer, cervical cancer, and lymphoid neoplasms (P values for heterogeneity in HRs <0.05). The HR (95% confidence interval) per 5 kg/m2 higher BMI was 1.17 (1.15–1.20) in men and 1.13 (1.11–1.15) in women for potential obesity-related cancers (51,690 cases), and 1.24 (1.22–1.26) in men and 1.12 (1.11–1.13) in women for established obesity-related cancers (84,384 cases). Interpretation: This study suggests a large number of potential obesity-related cancers could be added to already established ones. Importantly, the magnitudes of the associations were largely comparable to those of the already established obesity-related cancers. We also provide evidence of specific cancer subtypes driving some associations with BMI. Studies accounting for cancer-specific confounders are needed to confirm these findings.Peer reviewe

Prevalence of hypertension and associated factors among diabetic patients in Kilimanjaro region, northern Tanzania : A hospital-based cross-sectional study

Introduction: Hypertension is among the most common non-communicable diseases, being the major cause of premature deaths worldwide. The co-existence of hypertension and diabetes mellitus increases the risk of cardiovascular events and death. Objective: To determine the prevalence of hypertension and associated factors among individuals with type II diabetes mellitus in the Kilimanjaro region, northern Tanzania. Research design and methods: We conducted a cross-sectional study from June to September 2020 among 315 individuals with type II diabetes mellitus aged 18 years and above receiving care from two diabetic clinics in the Kilimanjaro region, northern Tanzania. Participants were selected using a systematic random sampling technique. The WHO Steps Survey for non-communicable diseases was used to collect data and analyzed using SPSS version 20. A multiple logistic regression model was used to estimate the odds ratios (OR) and 95% confidence intervals (CIs) for factors associated with hypertension adjusted for demographic, behavioral, and clinical characteristics. Results: The mean (±SD) age of 315 respondents was 58.62 ± 10.8 years and 58.4% were females. The prevalence of hypertension was 55.2% and was independently associated with older age; 60–69 years (OR = 2.75, 95%CI 1.14–6.64, p-value = 0.02) and ≥70 years (OR = 5.61; 95% CI: 1.65, 19.04), with history of cigarette smoking (OR = 3.98; 95% CI: 1.25, 12.72), and history of ischemic heart disease (OR = 16.86; 95% CI: 2.03, 140.3). Conclusion: More than half of individuals with diabetes in this study had co-existing hypertension, calling for routine and regular checkups of blood pressure at diabetic clinics. Special attention should be given to older individuals (≥60 years), smokers, and those with a history of ischemic heart disease for early prevention and management of adverse complications of diabetes and hypertension

Predictors of singleton preterm birth using multinomial regression models accounting for missing data: A birth registry-based cohort study in northern Tanzania.

BackgroundPreterm birth is a significant contributor of under-five and newborn deaths globally. Recent estimates indicated that, Tanzania ranks the tenth country with the highest preterm birth rates in the world, and shares 2.2% of the global proportion of all preterm births. Previous studies applied binary regression models to determine predictors of preterm birth by collapsing gestational age at birth to MethodsWe carried out a secondary analysis of cohort data from the KCMC zonal referral hospital Medical Birth Registry for 44,117 women who gave birth to singletons between 2000-2015. KCMC is located in the Moshi Municipality, Kilimanjaro region, northern Tanzania. Data analysis was performed using Stata version 15.1. Assuming a nonmonotone pattern of missingness, data were imputed using a fully conditional specification (FCS) technique under the missing at random (MAR) assumption. Multinomial regression models with robust standard errors were used to determine predictors of moderately to late ([32,37) weeks of gestation) and very/extreme (ResultsThe overall proportion of preterm births among singleton births was 11.7%. The trends of preterm birth were significantly rising between the years 2000-2015 by 22.2% (95%CI 12.2%, 32.1%, pConclusionsThe trends of preterm birth have increased over time in northern Tanzania. Policy decisions should intensify efforts to improve maternal and child care throughout the course of pregnancy and childbirth towards preterm birth prevention. For a positive pregnancy outcome, interventions to increase uptake and quality of ANC services should also be strengthened in Tanzania at all levels of care, where several interventions can easily be delivered to pregnant women, especially those at high-risk of experiencing adverse pregnancy outcomes

Predictors of perinatal death in the presence of missing data: A birth registry-based study in northern Tanzania.

BACKGROUND:More than five million perinatal deaths occur each year globally. Despite efforts put forward during the millennium development goals era, perinatal deaths continue to increase relative to under-five deaths, especially in low- and middle-income countries. This study aimed to determine predictors of perinatal death in the presence of missing data using birth registry data from Kilimanjaro Christian Medical Center (KCMC), between 2000-2015. METHODS:This was a retrospective cohort study from the medical birth registry at KCMC referral hospital located in Moshi Municipality, Kilimanjaro region, northern Tanzania. Data were analyzed using Stata version 15.1. Multiple imputation by fully conditional specification (FCS) was used to impute missing values. Generalized estimating equations (GEE) were used to determine the marginal effects of covariates on perinatal death using a log link mean model with robust standard errors. An exchangeable correlation structure was used to account for the dependence of observations within mothers. RESULTS:Among 50,487 deliveries recorded in the KCMC medical birth registry between 2000-2015, 4.2% (95%CI 4.0%, 4.3%) ended in perinatal death (equivalent to a perinatal mortality rate (PMR) of 41.6 (95%CI 39.9, 43.3) deaths per 1,000 births). After the imputation of missing values, the proportion of perinatal death remained relatively the same. The risk of perinatal death was significantly higher among deliveries from mothers who resided in rural compared to urban areas (RR = 1.241, 95%CI 1.137, 1.355), with primary education level (RR = 1.201, 95%CI 1.083, 1.332) compared to higher education level, with <4 compared to ≥4 antenatal care (ANC) visits (RR = 1.250, 95%CI 1.146, 1.365), with postpartum hemorrhage (PPH) (RR = 2.638, 95%CI 1.997, 3.486), abruption placenta (RR = 4.218, 95%CI 3.438, 5.175), delivered a low birth weight baby (LBW) (RR = 4.210, 95%CI 3.788, 4.679), male child (RR = 1.090, 95%CI 1.007, 1.181), and were referred for delivery (RR = 2.108, 95%CI 1.919, 2.317). On the other hand, deliveries from mothers who experienced premature rupture of the membranes (PROM) (RR = 0.411, 95%CI 0.283, 0.598) and delivered through cesarean section (CS) (RR = 0.662, 95%CI 0.604, 0.724) had a lower risk of perinatal death. CONCLUSIONS:Perinatal mortality in this cohort is higher than the national estimate. Higher risk of perinatal death was associated with low maternal education level, rural residence, <4 ANC visits, PPH, abruption placenta, LBW delivery, child's sex, and being referred for delivery. Ignoring missing values in the analysis of adverse pregnancy outcomes produces biased covariate coefficients and standard errors. Close clinical follow-up of women at high risk of experiencing perinatal death, particularly during ANC visits and delivery, is of high importance to increase perinatal survival

Suicidal Attempts among Secondary School-Going Adolescents in Kilimanjaro Region, Northern Tanzania

Suicide attempts among adolescents are common and can lead to death. The study aimed to determine the prevalence and factors associated with suicide attempts among secondary school-going adolescents in the Kilimanjaro region, northern Tanzania. The study used data from two repeated regional school-based student health surveys (RSHS), conducted in 2019 (Survey 1) and 2022 (Survey 2). Data were analyzed for secondary school students aged 13 to 17 years from four districts of the Kilimanjaro region. The study included 4188 secondary school-going adolescents: 3182 in Survey 1 and 1006 in Survey 2. The mean age in Survey 1 was 14 years and the median age in Survey 2 was 17 years ( p < 0.001). The overall prevalence of suicide attempts was 3.3% (3.0% in Survey 1 and 4.2% in Survey 2). Female adolescents had higher odds of suicide attempts (aOR = 3.0, 95% CI 1.2-5.5), as did those who felt lonely (aOR = 2.0, 95% CI 1.0-3.6), had ever been worried (aOR = 1.9, 95% CI 1.0-3.5), or had ever been bullied (aOR = 2.2, 95% CI 1.2-4.1). Suicidal attempts are prevalent among secondary school-going adolescents in the Kilimanjaro region, northern Tanzania. In-school programs should be established to prevent such attempts

Prevalence and factors associated with timely initiation of breastfeeding in Kilimanjaro region, northern Tanzania: a cross-sectional study

Background The World Health Organization (WHO) recommends early initiation of breastfeeding within 1 h as it confers many benefits to the child and prevents neonatal mortality. This study aimed to determine the prevalence and factors associated with timely initiation of breastfeeding in the Kilimanjaro region, northern Tanzania. Methods We analyzed secondary data for 866 participants from a population-based cross-sectional study conducted in April 2016 among mothers with children aged less than 5 years in three districts; Rombo, Same, and Moshi Municipal council in Kilimanjaro region, northern Tanzania. A multistage sampling selected study participants and interviewed using a questionnaire. The generalized linear model, with Poisson family and log-link function was used to estimate the prevalence ratios (PR) and 95% confidence intervals (CI) for factors associated with timely initiation of breastfeeding. Results The prevalence of timely initiation of breastfeeding was 71.1%. The vast majority of mothers (90.7%) gave colostrum, and less than a tenth (6.4%) gave pre-lacteal feed to their children. Adjusted for other factors, not giving children prelacteal feeds remained was significantly associated with a higher prevalence of timely initiation of breastfeeding (PR: 2.22, 95%CI 1.38, 3.56, p = 0.001). There was no significant association between other characteristics and the likelihood of timely initiation of breastfeeding in this study. Conclusion The prevalence of timely initiation of breastfeeding in the Kilimanjaro region was higher than the national estimate. The practice of not giving infants prelacteal feeds increased the likelihood of timely initiation of breastfeeding. There is a need to encourage mothers on the significance of recommended ANC visits and early initiation of breastfeeding to their infants to improve the practice

Prevalence and factors associated with tuberculosis among the mining communities in Mererani, Tanzania

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
