Epidemiological analysis of confirmed mpox cases, Burundi, 3 July to 9 September 2024.

We analysed mpox cases in Burundi from July to September 2024, following the introduction of Clade Ib virus. Of 607 samples from the whole population of suspected cases, 154 were PCR-positive, of whom 85 were children under 15 years, with a higher proportion of female children testing positive. Geographical analysis demonstrates case concentration in Bujumbura Mairie (91/154). Age- and sex-specific interventions, as well as community engagement, are important for outbreak containment, as are targeted public health strategies in Burundi.

Monkeypox Clade Ib virus introduction into Burundi: first findings, July to mid-August 2024.

We describe cases with monkeypox virus (MPXV) Clade Ib in Burundi from their first detection in July until 20 August 2024. Testing 442 people with vesicular lesions confirmed 170 cases (98 male; 72 female), 82 (48%) being < 15 years old. Differential diagnosis of the first 30 individuals testing MPXV negative revealed chickenpox in 20. Cases occurred in 26 of 49 Burundi health districts, but mostly in Bujumbura Nord (88/170; 67%). Case-derived MPXV genetic sequences from Burundi and South-Kivu (Democratic Republic of the Congo), clustered together in phylogenetic analysis.

'The body is difficult': reproductive navigation through sociality and corporeality in rural Burundi.

The route from family planning intentions to practices is not linear, it is contingent on different social factors including the preferences of individuals and couples, their gendered positions and bargaining power, the wider political, economic and social context, and also physical and bodily circumstances. We used qualitative data collected in rural Burundi between 2013 and 2016 to explore how these diverse factors influence reproductive navigation in a context framed by uncertainty and changing social norms. We describe representations of bodily (pre)dispositions for fertility and reproduction, such as the 'natural' capacity for birth spacing or the bodily capacity to use 'natural' (having a regular cycle) and 'modern' methods (not having negative side effects) that contribute collectively to an understanding of 'the body is difficult'. We found that despite these bodily constraints, women enact embodied agency to ensure livelihoods and social status, thus framing their reproductive intentions and practices. In the context of Burundi where corporeality is key to gendered social belonging, family planning programmes fail to respond to the needs and concerns of women and their embodied reproductive experiences.

Prevalence and associated risk factors assessment of bovine fasciolosis in the Imbo Region, Burundi.

Fasciolosis is a zoonosis that limits the productivity of ruminants worldwide, but there is a lack of information on its occurrence in Burundi. Therefore, this study aimed to fill the information gap by determining the prevalence and risk factors associated with bovine fasciolosis in the Imbo Region of Burundi. Two prevalence studies were conducted in parallel in the five communes of the five provinces in the Imbo region. In the first study, a total of 426 fecal samples were collected from randomly selected cattle farms and microscopically examined to determine Fasciola egg burden. Survey data on cattle husbandry were collected from owners of these cattle and analyzed to determine the risk factors for bovine fasciolosis. In the second study, 467 cattle were randomly selected in abattoirs and their livers were examined postmortem to determine liver fluke burdens. Data were entered separately into Microsoft Excel and analyzed using R software. The overall prevalence of bovine fasciolosis was 47.7% (42.9-52.4, 95% CI) for microscopic examination and 33.2% (28.9-37.5, 95% CI) for postmortem examinations. The majority of positive cattle (60.6%) had light intensity infections as determined by eggs per gram of feces (epg). Postmortem examinations corroborated these results and indicated that 80% of cattle had light intensity infections. Chi-square analysis showed a statistical association with the presence of bovine fasciolosis and the age, sex, and origin of cattle and the practices of cattle owners (P < 0.05).

Determinants of the unmet needs for information, education and communication on sexual health among single youths in Burundi.

The prevalence of HIV/AIDS among young people aged 15-24 in urban areas is at least 12 times higher among girls than boys in Burundi, while it is twice as high in Rwanda. The gap between the two countries could be narrowed if Burundi's single young people were provided with sufficient information about their sexual health through appropriate channels. The aim of this study was to examine the social and individual "determinants" of unmet needs for sexual health information, education and communication (IEC) among unmarried young boys and girls aged 15-24 in Burundi, using data from the 2016 Demographic and Health Survey (DHS). Data were analyzed at the bivariate level using cross-tabulations and chi-squared tests, and at the multivariate level using binary logistic regression methods. According to the results of the study, the 'determinants' of the phenomenon studied are, for both sexes, the size of the household, the age of the youths, their level of education, their knowledge of where to take the HIV/AIDS test and their region of residence; only in the case of boys do we find, in addition, the age of the head of the household, his level of education and the adolescents' exposure to the media; similarly, only in the case of girls do we find their economic activity and their perception of HIV/AIDS. Multisectoral IEC actions on sexual health for young people should therefore be strengthened in Burundi.

Au Burundi, en milieu urbain, la prévalence du VIH/SIDA est, chez les jeunes de 15-24 ans, au moins douze fois plus élevée chez les jeunes filles que chez les jeunes garçons, alors qu'au Rwanda elle est deux fois plus élevée. L'écart entre les deux pays serait réduit si les jeunes célibataires burundais recevaient suffisamment d'information sur leur santé sexuelle par des canaux appropriés. L'objectif de cette étude était de chercher au Burundi, chez les jeunes garçons et filles célibataires âgés de 15-24 ans, les « déterminants ¼ sociaux et individuels des Besoins Non Satisfaits (BNS) en Information, Education et Communication (IEC) en santé sexuelle à partir des données de l'Enquête Démographique et de Santé (EDS) de 2016. Ces dernières ont été analysées, au niveau bivarié, en recourant aux tableaux croisés et tests de chi-deux, et, au niveau multivarié, en recourant aux méthodes de régression logistique binaire. A en croire les résultats de l'étude, dans les deux sexes, les « déterminants ¼ du phénomène étudié sont la taille du ménage, l'âge du jeune, son niveau d'instruction, sa connaissance de l'endroit où faire le test de VIH/SIDA et sa région de résidence ; seulement, chez les garçons, on retrouve en plus l'âge du chef de ménage, son niveau d'instruction et l'exposition aux médias ; de même, seulement, chez les filles, on retrouve leur activité économique et leur perception du VIH/SIDA. Les actions multisectorielles d'IEC en santé sexuelle concernant les jeunes devraient alors être renforcées au Burundi.

Evaluation of effectiveness, acceptability and safety of thermal ablation in the treatment of cervical neoplasia in Burundi.

This longitudinal study aimed at evaluating the effectiveness, acceptability and safety of the thermal ablation procedure (TA) in the treatment of cervical neoplasia. Women referred to the Gynaecology ward for symptoms or for opportunistic screening were assessed by visual inspection with acetic acid (VIA) and colposcopy. Those with lesions eligible to ablation were counselled and treated by TA. They were inquired about the level of pain during the procedure, and their level of satisfaction. Patients were followed up at 6 weeks for any complication and reassessed by VIA and colposcopy at 12 months for any persistent or recurrent lesion and for any adverse event. A total of 86 women with a positive VIA test were included in the study. The mean age was 46 years (28-61 years). Most of the women did not complain about any adverse event during treatment; one-third presented mild pain or cramp. At the 6-week visit, watery discharge was the main adverse event reported. All women were highly satisfied with TA and most of them would recommend it. At the 12-month visit, 82 women were examined (95% follow-up rate), and the overall cure rate was 96% (low-grade lesions: 98%; high-grade lesions: 94%). Three women presented low- and high-grade lesions that were treated by TA. No major adverse event or hospitalisation after the treatment was reported. In conclusion, TA was an effective procedure with a high cure rate at the 1-year follow-up visit. It was acceptable and safe, with only minor short-term side-effects reported and with a high satisfaction rate among the patients.

Loss to follow-up of patients in HIV care in Burundi: A retrospective cohort study.

OBJECTIVE: The objective was to assess the loss to follow-up (LTFU) rates and associated factors amongst patients in HIV care in Burundi. METHODS: We conducted a retrospective cohort study in HIV-positive patients aged ≥15 years who started antiretroviral therapy (ART) between January 2015 and July 2020, with 31 December 2020 as the end point. The outcome of LTFU was defined as failure of a patient to report for drug refill within 90 days from the last appointment. Study data were extracted from the national AIDS Info database. The LTFU proportion was determined using the Kaplan-Meier method with the log-rank test, whereas LTFU risk factors were explored using the Cox regression model. RESULTS: A total of 29,829 patients on ART were included in the analysis. Cumulative incidence of LTFU was 2.3% at 12 months, 6.5% at 24 months, 12.7% at 36 months, 19.0% at 48 months, 24.1% at 60 months and 25.3% at 72 months. The overall LTFU incidence rate was 11.2 per 100 person-years of observation. The risk of LTFU was higher amongst patients who started ART after 2016 (adjusted hazard ratio [aHR] 1.75, 95% confidence interval [CI] 1.65-1.85) or within 7 days after diagnosis (aHR 1.27, 95% CI 1.21-1.35). CONCLUSION: Our findings demonstrate the relatively high incidence of LTFU in the Burundi HIV programme. Interventions targeting patients with risk factors for LTFU are particularly necessary.

Assessing the burden of Taenia solium cysticercosis in Burundi, 2020.

BACKGROUND: Taenia solium cysticercosis is a zoonotic disease that is endemic in many low- and middle-income countries where risk factors for disease transmission are present. The economic impact of cysticercosis on public health and on the pig production sector is not well known in many of those countries, including Burundi. This study aimed at estimating the burden of T. solium cysticercosis in Burundi including data on humans and pigs. METHODS: Epidemiological and economic data were collected from literature up to July 30, 2021 and governmental and non-governmental agencies. Direct and indirect costs for neurocysticercosis (NCC)-associated epilepsy and losses due to porcine cysticercosis were estimated to assess the economic burden, while the health burden was estimated using zoonotic disability-adjusted life years (zDALYs). Different probability distributions (Uniform, Beta, Dirichlet and Gamma) were applied depending on the type of epidemiological parameter. Monte Carlo simulations and 100,000 iterations were used to calculate the 95% uncertainty interval (UI) for each parameter and perform sensitivity analyses. RESULTS: In Burundi, 4.26 million USD (95% UI, 1,858,308-8,190,951) were estimated as economic impact due to T. solium cysticercosis in humans and pigs, of which 40.2% (95% UI, 10.3-75.1) of the total costs were due to NCC-associated epilepsy and 59.8% (95% UI, 24.9-89.7) of the losses due to porcine cysticercosis. The cost per NCC-associated epilepsy case was 72 USD (95% UI, 25-168), representing 30.8% of the GDP per capita in 2020. The probable incident cases and deaths for NCC-associated epilepsy were 9065 (95% UI, 2370-16,716) and 61 (95% UI, 16-114), respectively. More than 2 zDALYs (95% UI, 1.1-3.4) per thousand person-years was estimated, of which an average of 1.3 DALYs [0;0] (95% UI, 0.3-2.6) was due to NCC- associated epilepsy and 0.8 animal loss equivalents (ALEs) (95% UI, 0.3-1.5) due to porcine cysticercosis. CONCLUSIONS: This study provides evidence of a significant burden of T. solium cysticercosis for Burundi's population. We urge policy makers to use these evidence-based results and put T. solium cysticercosis on the public health agenda of the country. This study recommends urgent action to find solutions for integrated control strategies for T. solium cysticercosis in Burundi.

Prevalence, trend and determinants of adolescent childbearing in Burundi: a multilevel analysis of the 1987 to 2016-17 Burundi Demographic and Health Surveys data.

BACKGROUND: Very little is known about factors influencing adolescent childbearing despite an upward trend in adolescent childbearing prevalence in Burundi, and its perceived implications on the rapid population growth and ill-health of young mothers and their babies. To adress this gap, this study aimed to examine the prevalence, trends and determinants of adolescent childbearing in Burundi. METHODS: Secondary analyses of the 1987, 2010 and 2016-17 Burundi Demographic and Health Surveys (BDHS) data were conducted using STATA. Weighted samples of 731 (1987 BDHS), 2359 (2010 BDHS) and 3859 (2016-17BDHS) adolescent girls aged 15-19 years old were used for descriptive and trend analyses. Both bivariable and multivariable two-level logistic regression analyses were performed to identify the main factors associated with adolescent childbearing using only the 2016-17 BDHS data. RESULTS: The prevalence of adolescent childbearing increased from 5.9% in 1987 to 8.3% in 2016/17. Factors such as adolescent girls aged 18-19 years old (aOR =5.85, 95% CI: 3.54-9.65, p <  0.001), adolescent illiteracy (aOR = 4.18, 95% CI: 1.88-9.30, p <  0.001), living in poor communities (aOR = 2.19, 95% CI: 1.03-4.64, p = 0.042), early marriage (aOR = 9.28, 95% CI: 3.11-27.65, p <  0.001), lack of knowledge of any contraceptive methods (aOR = 5.33, 95% CI: 1.48-19.16, p = 0.010), and non-use of modern contraceptive methods (aOR = 24.48, 95% CI: 9.80-61.14), p <  0.001) were associated with higher odds of adolescent childbearing. While factors such as living in the richest household index (aOR = 0.52, 95% IC: 0.45-0.87, p = 0.00), living in West region (aOR = 0.26, 95%CI: 0.08-0.86, p = 0.027) or in South region (aOR = 0.31, 95% CI: 0.10-0.96, p = 0.041) were associated with lower odds of adolescent childbearing. CONCLUSION: Our study found an upward trend in adolescent childbearing prevalence and there were significant variations in the odds of adolescent childbearing by some individual and community-level factors. School-and community-based intervention programs aimed at promoting girls' education, improving socioeconomic status, knowledge and utilization of contraceptives and prevention of early marriage among adolescent girls is crucial to reduce adolescent childbearing in Burundi.

Déterminants du recours au test de dépistage du VIH chez les femmes en âge de procréer au Burundi.

INTRODUCTION: In sub-Saharan Africa, particularly in Burundi, uptake of HIV testing, which is fundamental to initiating treatment is relatively low. The present study aims to identify the individual and contextual determinants related to the uptake of HIV testing among women of childbearing age in this country. MATERIALS AND METHODS: This was an analysis of secondary data from Burundi's 2016-2017 demographic and health surveys. Our target population was women aged 15 to 49. Data were analyzed with the software stata 15.1. In bivariate analysis, the chi-square test and simple logistic regression allowed us to identify the candidate variables for modeling at the 20% threshold. Multilevel binary logistic regression made it possible to identify the individual and contextual determinants of the uptake of HIV / AIDS testing in these women. RESULTS: Out of a total of 8,537 women included in this study, 17.63% were between 15 and 24 years old, 46.44% between 25 and 34 and 35.93% between 35 and 49. The individual determinants of uptaking HIV testing were age, level of education, parity, marital status, decision-making power, and frequency of radio listening. Note that 1.36% of the use of the HIV testing was attributable to the region and the place of residence was an important variable of the context. CONCLUSION: This analysis of population data from DHS surveys in Burundi made it possible to identify the individual and contextual determinants influencing the uptake of HIV testing in Burundi. Further qualitative research should also address the contextual barriers that influence the uptake of screening.

The East African Community (EAC) mobile laboratory networks in Kenya, Burundi, Tanzania, Rwanda, Uganda, and South Sudan-from project implementation to outbreak response against Dengue, Ebola, COVID-19, and epidemic-prone diseases.

BACKGROUND: East Africa is home to 170 million people and prone to frequent outbreaks of viral haemorrhagic fevers and various bacterial diseases. A major challenge is that epidemics mostly happen in remote areas, where infrastructure for Biosecurity Level (BSL) 3/4 laboratory capacity is not available. As samples have to be transported from the outbreak area to the National Public Health Laboratories (NPHL) in the capitals or even flown to international reference centres, diagnosis is significantly delayed and epidemics emerge. MAIN TEXT: The East African Community (EAC), an intergovernmental body of Burundi, Rwanda, Tanzania, Kenya, Uganda, and South Sudan, received 10 million € funding from the German Development Bank (KfW) to establish BSL3/4 capacity in the region. Between 2017 and 2020, the EAC in collaboration with the Bernhard-Nocht-Institute for Tropical Medicine (Germany) and the Partner Countries' Ministries of Health and their respective NPHLs, established a regional network of nine mobile BSL3/4 laboratories. These rapidly deployable laboratories allowed the region to reduce sample turn-around-time (from days to an average of 8h) at the centre of the outbreak and rapidly respond to epidemics. In the present article, the approach for implementing such a regional project is outlined and five major aspects (including recommendations) are described: (i) the overall project coordination activities through the EAC Secretariat and the Partner States, (ii) procurement of equipment, (iii) the established laboratory setup and diagnostic panels, (iv) regional training activities and capacity building of various stakeholders and (v) completed and ongoing field missions. The latter includes an EAC/WHO field simulation exercise that was conducted on the border between Tanzania and Kenya in June 2019, the support in molecular diagnosis during the Tanzanian Dengue outbreak in 2019, the participation in the Ugandan National Ebola response activities in Kisoro district along the Uganda/DRC border in Oct/Nov 2019 and the deployments of the laboratories to assist in SARS-CoV-2 diagnostics throughout the region since early 2020. CONCLUSIONS: The established EAC mobile laboratory network allows accurate and timely diagnosis of BSL3/4 pathogens in all East African countries, important for individual patient management and to effectively contain the spread of epidemic-prone diseases.

African lates perches (Teleostei, Latidae, Lates): Paraphyly of Nile perch and recent colonization of Lake Tanganyika.

Lates perches of the genus Lates (Latidae) are large piscivorous fishes, with a strikingly disjunct distribution range in coastal areas and estuaries of the Indo-Pacific region and in some large African freshwater systems. Previous phylogenetic hypotheses based on osteological and ontogenetic data suggested paraphyly of the African representatives, or even the small Lake Tanganyika species assemblage, with respect to the remaining Lates species. Based on a multilocus phylogeny, however, we show that extant African lates perches are monophyletic. The Nile perch, L. niloticus, which is widely distributed in the Nilo-Sudan region and Central Africa, comprises three distinct lineages and is paraphyletic with respect to the four endemic Lake Tanganyika species. We find that diversification of extant African Lates happened only as recently as the Pliocene. With the extensive, in part much older fossil record, this suggests repeated extinction and (re-)colonization of hydrological systems. We further find that Lates started to diversify in Lake Tanganyika only in the Pleistocene, which is much more recent than other fish radiations endemic to Lake Tanganyika, implying that they radiated in the presence of other top predators already in this ecosystem.

Tubaramure, a Food-Assisted Integrated Health and Nutrition Program, Reduces Child Wasting in Burundi: A Cluster-Randomized Controlled Intervention Trial.

BACKGROUND: Little is known about the impact of food-assisted maternal and child health programs (FA-MCHN) on child wasting. OBJECTIVES: We assessed the impact of Tubaramure, a FA-MCHN program in Burundi, on child (0 to 24 months) wasting and the differential impacts by socio-economic characteristics and age. The program targeted women and their children during the first 1000 days and included 1) food rations, 2) strengthening and promotion of use of health services, and 3) behavior change communication (BCC). METHODS: We conducted a 4-arm, cluster-randomized, controlled trial (2010-2012). Clusters were defined as "collines" (communities). Impact was estimated using repeated cross-sectional data (n = ∼2620 children in each round). Treatment arms received household and individual (mother or child in the first 1000 days) food rations (corn-soy blend and micronutrient-fortified vegetable oil) from pregnancy to 24 months (T24 arm), from pregnancy to 18 months (T18), or from birth to 24 months (TNFP). All beneficiaries received the same BCC for the first 1000 days. The control arm received no rations or BCC. RESULTS: Wasting (weight-for-length Z-score <2 SD) increased from baseline to follow-up in the control group (from 6.5% to 8%), but Tubaramure had a significant (P < 0.05) protective effect on wasting [treatment arms combined, -3.3 percentage points (pp); T18, -4.5 pp] and on the weight-for-length z-score (treatment arms combined, +0.15; T24, +0.20; T18, +0.17). The effects were limited to children whose mother and household head had no education, and who lived in the poorest households. The largest effect was found in children 6 to 12 months of age: the group with the highest wasting prevalence. CONCLUSIONS: FA-MCHN programs in highly food-insecure regions can protect the most disadvantaged children from wasting. These findings are particularly relevant in the context of the economic crisis due to the coronavirus disease 2019 pandemic, which is expected to dramatically increase child wasting.

The lead-up to epidemic transmission: malaria trends and control interventions in Burundi 2000 to 2019.

Burundi has experienced an increase in malaria cases since 2000, reaching 843,000 cases per million inhabitants in 2019, a more than twofold increase compared to the early 2000s. Burundi thus contrasts the decreasing number of cases in many other African countries. To evaluate the impact of malaria control on this increase, data on interventions from 2000 to 2019 were compiled. Over this period, the number of health facilities increased threefold, and the number of tests 20-fold. The test positivity rate remained stable at around 50-60% in most years. Artemisinin-based combination therapy was introduced in 2003, initially using artesunate-amodiaquine and changed to artemether-lumefantrine in 2019/2020. Mass distribution campaigns of insecticide-treated bed nets were conducted, and indoor residual spraying and intermittent preventive treatment in pregnancy introduced. Thus, the increase in cases was not the result of faltering control activities. Increased testing was likely a key contributor to higher case numbers. Despite the increase in testing, the test positivity rate remined high, indicating that current case numbers might still underestimate the true burden.

Demographic and Fertility Characteristics of Contraceptive Clusters in Burundi.

Examining women's reproductive experiences over time reveals a more dynamic view of women's behaviors and needs than current status measures alone. This study uses sequence and cluster analyses, which are designed for identifying patterns and subgroups in longitudinal data. We apply these methods to contraceptive calendar data in Burundi to identify discrete clusters of women based on contraceptive and pregnancy behaviors over the past 5 years. We identify six unique clusters; three characterized by no use of contraception (85 percent of women) and three by use (16 percent). The Quiet Calendar cluster (42 percent) comprise women who neither experience pregnancy nor use contraception. Family Builder 1 (25 percent) and 2 (18 percent) both include women who experience two pregnancies, but differ in unmet need and lifetime experience with contraception. Modern Mother (8 percent), Consistently Covered Mother (6 percent), and Traditional Mother (2 percent) clusters differ by type of contraception used following pregnancy. Factors associated with cluster membership are need for family planning, lifetime experience with contraception, marital status, pregnancy intention, and age. This clustering approach provides a new, more holistic way to measure the diverse needs across unique subpopulations and can inform the development of multifaceted, adaptable strategies to meet women's dynamic fertility needs over the reproductive life course.

Empirical analysis of socio-economic determinants of maternal health services utilisation in Burundi.

BACKGROUND: Timely and appropriate health care during pregnancy and childbirth are the pillars of better maternal health outcomes. However, factors such as poverty and low education levels, long distances to a health facility, and high costs of health services may present barriers to timely access and utilisation of maternal health services. Despite antenatal care (ANC), delivery and postnatal care being free at the point of use in Burundi, utilisation of these services remains low: between 2011 and 2017, only 49% of pregnant women attended at least four ANC visits. This study explores the socio-economic determinants that affect utilisation of maternal health services in Burundi. METHODS: We use data from the 2016-2017 Burundi Demographic and Health Survey (DHS) collected from 8941 women who reported a live birth in the five years that preceded the survey. We use multivariate regression analysis to explore which individual-, household-, and community-level factors determine the likelihood that women will seek ANC services from a trained health professional, the number of ANC visits they make, and the choice of assisted childbirth. RESULTS: Occupation, marital status, and wealth increase the likelihood that women will seek ANC services from a trained health professional. The likelihood that a woman consults a trained health professional for ANC services is 18 times and 16 times more for married women and women living in partnership, respectively. More educated women and those who currently live a union or partnership attend more ANC visits than non-educated women and women not in union. At higher birth orders, women tend to not attend ANC visits. The more ANC visits attended, and the wealthier women are; the more likely they are to have assisted childbirth. Women who complete four or more ANC visits are 14 times more likely to have an assisted childbirth. CONCLUSIONS: In Burundi, utilisation of maternal health services is low and is mainly driven by legal union and wealth status. To improve equitable access to maternal health services for vulnerable population groups such as those with lower wealth status and unmarried women, the government should consider certain demand stimulating policy packages targeted at these groups.

Mind the gap: what explains the rural-nonrural inequality in diarrhoea among under-five children in low and medium-income countries? A decomposition analysis.

BACKGROUND: Diarrhoea poses serious health problems among under-five children (U5C) in Low-and Medium-Income Countries (LMIC) with a higher prevalence in rural areas. A gap exists in knowledge on factors driving rural-non-rural inequalities in diarrhoea development among U5C in LMIC. This study investigates the magnitude of rural-non-rural inequalities in diarrhoea and the roles of individual-level and neighbourhood-level factors in explaining these inequalities. METHODS: Data of 796,150 U5C, from 63,378 neighbourhoods across 57 LMIC from the most recent Demographic and Health Survey (2010-2018) was analysed. The outcome variable was the recent experience of diarrhoea while independent variables consist of the individual- and neighbourhood-level factors. Data were analysed using multivariable Fairlie decomposition at p < 0.05 in Stata Version 16 while visualization was implemented in R Statistical Package. RESULTS: Two-thirds (68.0%) of the children are from rural areas. The overall prevalence of diarrhoea was 14.2, 14.6% vs 13.4% among rural and non-rural children respectively (p < 0.001). From the analysis, the following 20 countries showed a statistically significant pro-rural inequalities with higher odds of diarrhoea in rural areas than in nonrural areas at 5% alpha level: Albania (OR = 1.769; p = 0.001), Benin (OR = 1.209; p = 0.002), Burundi (OR = 1.399; p < 0.001), Cambodia (OR = 1.201; p < 0.031), Cameroon (OR = 1.377; p < 0.001), Comoros (OR = 1.266; p = 0.029), Egypt (OR = 1.331; p < 0.001), Honduras (OR = 1.127; p = 0.027), India (OR = 1.059; p < 0.001), Indonesia (OR = 1.219; p < 0.001), Liberia (OR = 1.158; p = 0.017), Mali (OR = 1.240; p = 0.001), Myanmar (OR = 1.422; p = 0.004), Namibia (OR = 1.451; p < 0.001), Nigeria (OR = 1.492; p < 0.001), Rwanda (OR = 1.261; p = 0.010), South Africa (OR = 1.420; p = 0.002), Togo (OR = 1.729; p < 0.001), Uganda (OR = 1.214; p < 0.001), and Yemen (OR = 1.249; p < 0.001); and pro-non-rural inequalities in 9 countries. Variations exist in factors associated with pro-rural inequalities across the 20 countries. Overall main contributors to pro-rural inequality were neighbourhood socioeconomic status, household wealth status, media access, toilet types, maternal age and education. CONCLUSIONS: The gaps in the odds of diarrhoea among rural children than nonrural children were explained by individual-level and neighbourhood-level factors. Sustainable intervention measures that are tailored to country-specific needs could offer a better approach to closing rural-non-rural gaps in having diarrhoea among U5C in LMIC.

Socioeconomic inequalities in lifestyle risk factors across low- and middle-income countries.

BACKGROUND: The heavy and ever rising burden of non-communicable diseases (NCDs) in low- and middle-income countries (LMICs) warrants interventions to reduce their underlying risk factors, which are often linked to lifestyles. To effectively supplement nationwide policies with targeted interventions, it is important to know how these risk factors are distributed across socioeconomic segments of populations in LMICs. This study quantifies the prevalence and socioeconomic inequalities in lifestyle risk factors in LMICs, to identify policy priorities conducive to the Sustainable Development Goal of a one third reduction in deaths from NCDs by 2030. METHODS: Data from 1,278,624 adult respondents to Demographic & Health Surveys across 22 LMICs between 2013 and 2018 are used to estimate crude prevalence rates and socioeconomic inequalities in tobacco use, overweight, harmful alcohol use and the clustering of these three in a household. Inequalities are measured by a concentration index and correlated with the percentage of GDP spent on health. We estimate a multilevel model to examine associations of individual characteristics with the different lifestyle risk factors. RESULTS: The prevalence of tobacco use among men ranges from 59.6% (Armenia) to 6.6% (Nigeria). The highest level of overweight among women is 83.7% (Egypt) while this is less than 12% in Burundi, Chad and Timor-Leste. 82.5% of women in Burundi report that their partner is "often or sometimes drunk" compared to 1.3% in Gambia. Tobacco use is concentrated among the poor, except for the low share of men smoking in Nigeria. Overweight, however, is concentrated among the better off, especially in Tanzania and Zimbabwe (Erreygers Index (EI) 0.227 and 0.232). Harmful alcohol use is more concentrated among the better off in Nigeria (EI 0.127), while Chad, Rwanda and Togo show an unequal pro-poor distribution (EI respectively - 0.147, - 0.210, - 0.266). Cambodia exhibits the largest socioeconomic inequality in unhealthy household behaviour (EI - 0.253). The multilevel analyses confirm that in LMICs, tobacco and alcohol use are largely concentrated among the poor, while overweight is concentrated among the better-off. The associations between the share of GDP spent on health and the socioeconomical distribution of lifestyle factors are multidirectional. CONCLUSIONS: This study emphasizes the importance of lifestyle risk factors in LMICs and the socioeconomic variation therein. Given the different socioeconomic patterns in lifestyle risk factors - overweight patters in LMICs differ considerably from those in high income countries- tailored interventions towards specific high-risk populations are warranted to supplement nationwide policies.

Key factors influencing multidrug-resistant tuberculosis in patients under anti-tuberculosis treatment in two centres in Burundi: a mixed effect modelling study.

BACKGROUND: Despite the World Health Organization efforts to expand access to the tuberculosis treatment, multidrug resistant tuberculosis (MDR-TB) remains a major threat. MDR-TB represents a challenge for clinicians and staff operating in national tuberculosis (TB) programmes/centres. In sub-Saharan African countries including Burundi, MDR-TB coexists with high burden of other communicable and non-communicable diseases, creating a complex public health situation which is difficult to address. Tackling this will require targeted public health intervention based on evidence which well defines the at-risk population. In this study, using data from two referral anti-tuberculosis in Burundi, we model the key factors associated with MDR-TB in Burundi. METHODS: A case-control study was conducted from 1stAugust 2019 to 15th January 2020 in Kibumbu Sanatorium and Bujumbura anti-tuberculosis centres for cases and controls respectively. In all, 180 TB patients were selected, comprising of 60 cases and 120 controls using incidence density selection method. The associated factors were carried out by mixed effect logistic regression. Model performance was assessed by the Area under Curve (AUC). Model was internally validated via bootstrapping with 2000 replications. All analysis were done using R Statistical 3.5.0. RESULTS: MDR-TB was more identified among patients who lived in rural areas (51.3%), in patients' residence (69.2%) and among those with a household size of six or more family members (59.5%). Most of the MDR-TB cases had already been under TB treatment (86.4%), had previous contact with an MDR-TR case (85.0%), consumed tobacco (55.5%) and were diabetic (66.6 %). HIV prevalence was 32.3 % in controls and 67.7 % among cases. After modelling using mixed effects, Residence of patients (aOR= 1.31, 95%C: 1.12-1.80), living in houses with more than 6 family members (aOR= 4.15, 95% C: 3.06-5.39), previous close contact with MDR-TB (aOR= 6.03, 95% C: 4.01-8.12), history of TB treatment (aOR= 2.16, 95% C: 1.06-3.42), tobacco consumption (aOR = 3.17 ,95% C: 2.06-5.45) and underlying diabetes' ( aOR= 4.09,95% CI = 2.01-16.79) were significantly associated with MDR-TB. With 2000 stratified bootstrap replicates, the model had an excellent predictive performance, accurately predicting 88.15% (95% C: 82.06%-92.8%) of all observations. The coexistence of risk factors to the same patients increases the risk of MDR-TB occurrence. TB patients with no any risk factors had 17.6% of risk to become MDR-TB. That probability was respectively three times and five times higher among diabetic and close contact MDR-TB patients. CONCLUSION: The relatively high TB's prevalence and MDR-TB occurrence in Burundi raises a cause for concern especially in this context where there exist an equally high burden of chronic diseases including malnutrition. Targeting interventions based on these identified risk factors will allow judicious channel of resources and effective public health planning.

Intergenerational maltreatment in parent-child dyads from Burundi, Africa: Associations among parental depression and connectedness, posttraumatic stress symptoms, and aggression in children.

Studies investigating the associations between histories of childhood maltreatment (CM) in parent-child dyads have primarily involved samples from high-income countries; however, CM rates are higher in low- and middle-income countries. The present study aimed to examine the (a) association between maltreatment in parents and maltreatment of their children through risk (i.e., parent depression) and protective (i.e., parent-child connectedness) factors and (b) associations between CM in children with aggression through posttraumatic stress symptoms (PTSS) and peer/sibling victimization. Participants were 227 parent-child dyads from Burundi, Africa, a low-income country. Parents were 18 years of age or older, and children were 12-18 years (M = 14.76, SD = 1.88, 57.7% female). Among parents, 20.7%-69.5% of participants reported a history of physical and emotional abuse and neglect; among children, the rates of sexual, physical, and emotional abuse ranged from 14.5% to 89.4%. A history of CM in parents was associated with CM in children, B = 0.19, p < .01, and CM in parents was indirectly associated with CM in children through parent-child connectedness, ß = .04, 95% CI [.01, .10], and parental depression, ß = .08, 95% CI [.03, .15]. In children, maltreatment was positively associated with peer/sibling victimization, and CM was associated with aggression, ß = .07, 95% CI [.04, 0.11], through PTSS but not via peer/sibling victimization. Continued efforts to improve CM-related preventive strategies and the accessibility of prevention services are needed to reduce CM in low-income countries such as Burundi.
