The effect of UNIMMAP multiple micronutrient supplements versus iron-folic acid and placebo in anemia reduction among women of reproductive age in Kebribeyah Woreda, Somali Regional State, Ethiopia: a study protocol for a community-based individual RCT.

BACKGROUND: Women of reproductive age (WRA) in developing countries are often at risk of micronutrient deficiencies due to inadequate intakes and excessive losses. OBJECTIVE: The purpose of this trial is to assess the effectiveness of United Nations International Multiple Micronutrient Antenatal Preparation-Multiple Micronutrient Supplements (UNIMMAP-MMS) versus iron-folic acid (IFA) among WRA in reducing anemia. METHODS: Three parallel groups of WRA will participate in a community-based, individually randomized, double-blinded, placebo-controlled superiority trial. After consent, the sample of 375 mildly or moderately anemic women based on hemoglobin by Hemocue will be randomly assigned across two interventions and one control arm. Trial participants in intervention arms will receive UNIMMAP-MMS or IFA while those in the control arm will receive placebos twice a week for 17 weeks. The primary outcome will be a change in mean hemoglobin (Hb) concentrations. Outcome assessors and study participants will be blinded to the type of supplements and study arm. DISCUSSION: The World Health Organization (WHO) added UNIMMAP-MMS to its essential medicine lists in 2021 but recommended rigorous study. Several factors in addition to inadequate intakes of iron and folic acid contribute to the high prevalence of anemia among WRA in the Somali region. The findings of this study will provide evidence on the effect of UNIMMAP-MMS and IFA on Hb concentrations and anemia prevalence among anemic WRA. TRIAL REGISTRATION: ClinicalTrials.gov NCT05682261.

School feeding in Ethiopia: a scoping review.

INTRODUCTION: Undernutrition is a major public health problem in developing countries, especially in Sub-Saharan Africa. Undernourished children are smaller and have low weight. To solve this issue, school feeding (corn-soya blend, vegetable oil) started in 1994 in Ethiopia. Thus, this scoping review aims to map the evidence relating to school feeding programs and their potential role in managing children`s nutrition in Ethiopia. METHODS: This scoping review is informed by the methodological framework of Arksey & O'Malley for scoping reviews and recommendations on the framework by Levac and colleagues. The databases searched included the Education Resources Information Centre, International Initiative for Impact Evaluation, Cochrane Library, MEDLINE, and Google Scholar. To ensure its comprehensive search, grey literature sources were searched. The search was undertaken on 26 April 2023. Studies on school feeding, such as coverage, and studies that evaluate the educational and nutritional impacts of school feeding in Ethiopia, regardless of study designs, were included. Reports (publications) about school feeding without scientific methodology were excluded. RESULT: Twenty-seven studies were included in this review. It includes cross-sectional, prospective cohort, laboratory-based analysis, experimental, case study, and qualitative study designs. The school feeding program results were inconclusive, while some indicate a positive effect on body mass index, height, thinness, anemia, weight, dropout rate, class attendance, and enrollment. The others showed that the school feeding program did not affect stunting, thinness, weight, hemoglobin level, enrollment, attendance, dropout rate, and academic achievement. Factors affecting school feeding programs negatively include poor quality food and financial constraints. However, no literature on school feeding program coverage was found. CONCLUSION: School feeding programs improved nutritional status, and academic performance, although some studies show any effect. Poor-quality food provisions and financial constraints affect school feeding programs. There are mixed findings, and further research is required to determine the effect of school feeding programs conclusively. To ensure the program's sustainability, it should be supported by a national policy, and budget allocation is needed. In addition, more evidence should be generated to show the coverage of school feeding programs in Ethiopia.

Prevalence and factors associated with inconsistent condom use among female sex workers in Ethiopia: findings from the national biobehavioral survey, 2020.

BACKGROUND: The HIV prevalence among Ethiopian female sex workers (FSWs) is estimated to be around 18.5%, which implies that FSWs' sexual partners are significantly exposed to HIV infection and that may be a major factor in HIV transmission in the community. However, it has long been known that using condoms correctly and consistently is an extremely cost-effective global method for preventing HIV infection, but inconsistent condom use (ICU) would pose the greatest proximal risk of HIV acquisition and transmission. Understanding the prevalence and associated risk factors of inconsistence condom use among FSWs would inform policymakers to design programmatic interventions in the context of Ethiopia. METHODS: This analysis used data from the 'National HIV and STIs Bio-behavioral Survey (NHSBS)', which was conducted between December 2019 up to May 2020 by using a respondent-driven sampling (RDS) technique among FSWs aged 15 years and older who were selling sex in selected major cities and towns in Ethiopia. A multi-level logistic regression model was fitted to assess town and individual-level variations simultaneously to adjust hierarchical variations. Statistical significance was determined by using a P-value less than 0.05 with a 95% confidence interval (CI) not including one. RESULTS: Overall, 6,085 FSWs from 16 cities and towns participated in the study. The prevalence of inconsistent condom use across the 16 cities and towns was 17.1% [95% CI (16.5, 17.8)]. Inconsistent condom use was significantly higher among FSWs who had depression compared to those without depression [AOR = 1.43; 95% CI (1.13,1.82)], used any drug [AOR = 1.43; 95% CI (1.14-1.79)], had history of sexual violence [AOR = 1.75; 95% CI (1.43, 2.16)], changed sex selling location [AOR = 1.27; 95% CI (1.06, 1.51)], longer period of sex selling experience [AOR = 3.01; 95% CI (2.27, 3.99)], ever had anal sex [AOR = 2.74; 95% CI (2.15, 3.5)], had ≥ 2 non-paying sexual partner [AOR = 2.99; 95% CI(2.26, 3.95)], selling sex `in more than two cities [AOR = 3.01;95% CI (2.27, 3.99)], who lacked access to condom [AOR = 2.1; 95% CI (1.69, 2.67)], and did not have HIV knowledge [AOR = 1.39; 95% CI (1.15, 1.68)]. CONCLUSION: Inconsistent condom use among FSWs is prevalent in Ethiopia and is associated with marital status, education status, depression, alcohol drinking, drug use, sexual violence, being raped, lack of knowledge about HIV, practising anal sex, selling sex in different locations, having more than two non-paying sexual partners, working in more than two cities, and lack of access to condom at the workplace. Programme interventions to enhance consistent condoms use among FSWs need to take these factors into consideration.

Access to water, sanitation and hygiene (WASH) services and drinking water contamination risk levels in households of Bishoftu Town, Ethiopia: A cross-sectional study.

Background and Aims: Access to safe drinking water, sanitation, and hygiene is a fundamental human right and essential to control infectious diseases. However, many countries, including Ethiopia, do not have adequate data to report on basic water, sanitation, and hygiene (WASH) services. Although contaminated drinking water spreads diseases like cholera, diarrhea, typhoid, and dysentery, studies on drinking water contamination risk levels in households are limited in Ethiopia. Therefore, closing this gap needs investigation. Methods: A community-based cross-sectional study was conducted. A total of 5350 households were included. A systematic, simple random sampling technique was used to select the participants. The information was gathered through in-person interviews using a standardized questionnaire. Furthermore, 1070 drinking water samples were collected from household water storage. Results: This investigation revealed that 9.8%, 83.9%, and 4.9% of households used limited, basic, and safely managed drinking water services, respectively. Besides, 10.2%, 15.7% and 59.3% of households used safely managed, basic and limited sanitation services, respectively. Yet, 10.6% and 4.2% of households used unimproved sanitation facilities and open defecation practices. Also, 40.5% and 19.4% of households used limited and basic hygiene services. On the other hand, 40.1% of households lacked functional handwashing facilities. In this study, 12.1%, 26.3%, and 42% of households' drinking water samples were positive for Escherichia coli, fecal coliforms, and total coliforms, respectively. Also, 5.1% and 4.5% of households' drinking water samples had very high and high contamination risk levels for E. coli, respectively. We found that 2.5% and 11.5% of households and water distributors had unacceptable fluoride concentrations, respectively. Conclusion: The majority of households in Bishoftu town lack access to safely managed sanitation, drinking water, and basic hygiene services. Many households' water samples had very high and high health risk levels. Hence, the government and partner organizations should implement water and sanitation safety plans.

Associations of WHO/UNICEF Joint Monitoring Program (JMP) Water, Sanitation and Hygiene (WASH) Service Ladder service levels and sociodemographic factors with diarrhoeal disease among children under 5 years in Bishoftu town, Ethiopia: a cross-sectional study.

OBJECTIVE: To determine the associations of WHO/UNICEF Joint Monitoring Program Water, Sanitation and Hygiene (WASH) Service Ladder service levels and sociodemographic factors with diarrhoeal disease among children under 5 years in Bishoftu town, Ethiopia. DESIGN: A community-based cross-sectional study. SETTING: Bishoftu town, Ethiopia, January-February 2022. PARTICIPANTS: A total of 1807 mothers with at least one child under 5 years were included. Sociodemographic and WASH variables were collected using a structured questionnaire. 378 drinking water samples were collected. OUTCOME: The response variable was diarrhoeal disease among children under 5 years. RESULTS: The 2-week prevalence of diarrhoeal disease among children under 5 years was 14.8%. Illiteracy (adjusted OR 3.15; 95% CI 1.54 to 6.47), occupation (0.35; 0.20 to 0.62), mother's age (1.63; 1.15 to 2.31), family size (2.38; 1.68 to 3.39), wealth index (5.91; 3.01 to 11.59), residence type (1.98; 1.35 to 2.90), sex of the child (1.62; 1.17 to 2.24), child's age (3.52; 2.51 to 4.93), breastfeeding status (2.83; 1.74 to 4.59), food storage practice (3.49; 1.74 to 8.26), unimproved drinking water source (8.16; 1.69 to 39.46), limited drinking water service (4.68; 1.47 to 14.95), open defecation practice (5.17; 1.95 to 13.70), unimproved sanitation service (2.74; 1.60 to 4.67), limited sanitation service (1.71; 1.10 to 2.65), no hygiene service (3.43; 1.91 to 6.16) and limited hygiene service (2.13; 1.17 to 3.86) were significantly associated with diarrhoeal disease. CONCLUSION: In this study, diarrhoea among children is a significant health issue. Child's age, drinking water service, residence type and hygiene service were the largest contributors with respect to the prevalence of diarrhoeal disease. This investigation provides information that could help to inform interventions to reduce childhood diarrhoea. The findings suggest that state authorities should initiate robust WASH strategies to achieve the Sustainable Development Goal 3 agenda.

Adherence to infection prevention and control measures and risk of exposure among health-care workers: A cross-sectional study from the early period of COVID-19 pandemic in Addis Ababa, Ethiopia.

Background and Aim: Healthcare workers (HCWs) are considered a high-risk group for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure, ascribed to the amount of time they spend in health-care facilities (HCFs). This study aimed to assess HCWs' compliance with Infection Prevention and Control (IPC) procedures and the risk of exposure during the early period of the pandemic in Addis Ababa, Ethiopia. Methods: A descriptive cross-sectional survey was conducted from June to September 2020. With a response rate of 79.2%, a standardized questionnaire was administered among 247 HCWs, working in eight HCFs. Descriptive and multivariate regression analysis was carried out in STATA version 16. Results: About 22.5% (55) of the HCWs had proper adherence to IPC procedures. Of the total participants, 28.2% (69) had proper use of Personal Protective Equipment (PPE), 40% (98) had proper hand hygiene practices, and 33.1% (81) had frequently cleaned their working environment. HCWs who received training on IPC protocols were four times more likely to follow IPC standards than those with no training (adjusted odds ratio [AOR] = 3.93; 95% confidence interval [CI]: 1.46, 10.58). Besides, HCWs working in treatment centers were four times more likely to follow IPC standards than those working in conventional hospitals (AOR = 3.61; 95% CI:1.63, 8.02). Nurses were four times more likely to have adherence to IPC measures than cleaners and runners (AOR = 4.37; 95% CI: 1.38-13.88). Conclusion: The nature and magnitude of the pandemic did not introduce the required degree of adherence to IPC procedures, per se does not match the level of diligence needed to halt SARS-CoV-2 transmission. Our finding suggested that providing periodic training of HCWs with particular emphasis on nonclinical staff is commendable. Furthermore, it is necessary to maintain resilent IPC in HCF through continous follow up and safety drills, to assess the readiness of HFCs' adherance to IPC measures under normal circumstances, which could improve prepardeness for an effective response during epidemics.

Co-occurrence of iron, folate, and vitamin A deficiency among pregnant women in eastern Ethiopia: a community-based study.

BACKGROUND: It is well known that the magnitude of undernutrition in Ethiopia is unacceptably high. The burden of co-occurrence of iron, folate, and vitamin A deficiency, on the other hand, has received less attention. Thus, in this study, we looked at the prevalence of iron, folate, and vitamin A deficiency in pregnant women in eastern Ethiopia. METHODS: A community-based cross-sectional study was conducted among 397 pregnant women in Haramaya district, eastern Ethiopia. An interview-assisted questionnaire and blood serum were collected from pregnant women using standard techniques and shipped to an EPHI for micronutrient analysis. Factors associated with the co-occurrence of iron, folate, and vitamin A deficiency were identified using binary and multiple logistic regressions. RESULTS: According to this study, 81.6% of the participants were deficient in at least one micronutrient, and 53.53.2% were deficient in two or more. Women who did not receive iron-folic acid supplementation (AOR = 2.44; 95% CI = 1.52-3.92), did not attend Antenatal care (ANC) follow up (AOR = 2.88; 95% CI = 1.81-4.61), and reported low consumption of diversified diet (AOR = 2.18 (95% CI = 1.35-3.51) had a higher risk of co-occurrence of iron, folate, and vitamin A deficiency. CONCLUSION: This study found that more than half of pregnant women were in multiple micronutrients, indicating a major public health issue. In addition to the IFA supplementation programs that are already in place, there is a need for multiple micronutrient supplementation.

Effect of enhanced nutrition services with community-based nutrition services on the diet quality of young children in Ethiopia.

Poor diet quality related to inadequate complementary feeding is a major public health problem in low and middle-income countries including Ethiopia. Low dietary diversity has been linked to negative health outcomes in children. To provide a package of interventions to close nutritional gaps through agriculture, the Sustainable Undernutrition Reduction in Ethiopia (SURE) programme was set up as a multi-sectoral initiative and the results of combined effects of community-based and enhanced nutrition services, compared to community-based alone, on diet diversity and diet quality of complementary feeding of young children are presented. The study used pre- and post-intervention design. Baseline (n = 4980) data were collected from May to July 2016, and follow-up (n = 2419) data from December 2020 to January 2021. From 51 intervention districts having the SURE programme, 36 intervention districts were randomly selected for baseline and 31 for the follow-up survey. The primary outcome was diet quality: minimum dietary diversity (MDD), minimum meal frequency (MMF) and minimum acceptable diet (MAD). Comparing endline to baseline over the 4.5-year intervention, the use of standard community-based nutrition services of growth monitoring and promotion increased (16%-46%), as did enhanced nutrition services of infant and young child feeding counselling, and agricultural advising (62%-77%). Women involved in home gardening significantly increased (73%-93%); however, household production of food decreased yet consumption of most own-grown foods increased. Importantly, MAD and MDD increased four-fold. The SURE intervention programme was associated with improvements in complementary feeding and diet quality through enhanced nutrition services. This suggests programmes targeted at nutrition-sensitive practices can improve child feeding in young children.

Serum folate deficiency and associated factors among pregnant women in Haramaya District, Eastern Ethiopia: a community-based study.

OBJECTIVES: We aimed to estimate the prevalence of folate deficiency and contributing factors among pregnant women. DESIGN: A community-based, cross-sectional study. SETTING: Haramaya District, Eastern Ethiopia. PARTICIPANTS: Four hundred and forty-six pregnant women participated in the study. PRIMARY OUTCOME MEASURE: The prevalence of folate deficiency and risk factors. RESULTS: Overall, the prevalence of folate deficiency was 49.3% (95% CI 44.6% to 54.1%). Pregnant women with iron deficiency anaemia were 2.94 times more likely to develop folate deficiency (adjusted OR (AOR)=2.9, 95% CI 1.9 to 4.7). Respondents with good knowledge of folate-rich foods (AOR=0.3, 95% CI 0.1 to 0.7) and those who took iron and folic acid supplementation (AOR=0.6, 95% CI 0.4 to 0.9) during their pregnancy were less likely to develop folate deficiency. CONCLUSIONS: In this study, a considerable proportion of pregnant women had folate deficiency during their pregnancy. Therefore, it is critical that nutritional treatment, education and counselling be strengthened to facilitate iron and folic acid supplementation during pregnancy.

Ethiopia National Food and Nutrition Survey to inform the Ethiopian National Food and Nutrition Strategy: a study protocol.

INTRODUCTION: Ethiopia has made significant progress in reducing malnutrition in the past two decades. Despite such improvements, a substantial segment of the country's population remains chronically undernourished and suffers from micronutrient deficiencies and from increasing diet-related non-communicable diseases such as diabetes, hypertension and cancer. This survey aims to assess anthropometric status, dietary intake and micronutrient status of Ethiopian children, women and adolescent girls. The study will also assess coverage of direct and indirect nutrition-related interventions and map agricultural soil nutrients. The survey will serve as a baseline for the recently developed Ethiopian Food System Transformation Plan and will inform the implementation of the National Food and Nutrition Strategy. METHODS AND ANALYSIS: As a population-based, cross-sectional survey, the study will collect data from the 10 regions and 2 city administrations of Ethiopia. The study population will be women of reproductive age, children aged 0-59 months, school-aged children and adolescent girls. A total of 16 596 households will be surveyed, allowing the generation of national and regional estimates. A two-stage stratified cluster sampling procedure will be used to select households. In the first stage, 639 enumeration areas (EAs) will be selected using probability-proportional-to-size allocation. In the second stage, 26 eligible households will be selected within each EA using systematic random selection. Primary outcomes include coverage of direct and indirect nutrition interventions, infant and young child feeding (IYCF) practices, food insecurity, dietary intakes, mental health, anthropometric status, micronutrient status and soil nutrient status. ETHICS AND DISSEMINATION: The protocol was fully reviewed and approved by the Institutional Review Board of the Ethiopian Public Health Institute (protocol no: EPHI-IRB-317-2020). The study is based on voluntary participation and written informed consent is required from study participants. The findings will be disseminated via forums and conferences and will be submitted for publication in peer-reviewed journals.

Nutrient Density and Microbial Safety of Open-Air-Dried Beef Meat and Its Biochemical and Organ Histopathology Effects in Albino Rats: A Promising Ingredient for Complementary Food Formulation.

Introduction: Dried beef meat is a major source of essential fatty acids, minerals, and vitamins that are digestible and absorbable, thus could be a potential source of nutrients in complementary food formulations. Composition, microbial safety, and organ function tests were analyzed, and histopathological effect of air-dried beef meat powder was determined in rat model. Methods: Three groups of diets were given for the three groups of animals: (1) standard rat diet, (2) meat powder+standard rat diet (1 : 1 formulation), and (3) dried meat powder. A total of 36 Wistar albino rats (18 males and 18 females) of 4-8 weeks old were used and randomly assigned to the experiments. After acclimatization for one week, the experimental rats were followed for 30 days. Microbial analysis, nutrient composition, organ histopathology (liver and kidney), and organ function tests were conducted from serum samples taken from the animals. Results: Protein, fat, fiber, ash, utilizable carbohydrate, and energy contents of meat powder on a dry weight basis were 76.12 ± 3.68, 8.19 ± 2.01, 0.56 ± 0.38, 6.45 ± 1.21, 2.79 ± 0.38 g/100 g, and 389.30 ± 3.25 kcal/100 g, respectively. Meat powder could be also a potential source of minerals such as potassium (766.16 ± 77.26 mg/100 g), phosphorus (150.35 ± 16.26 mg/100 g), calcium (18.15 ± 7.80 mg/100 g), zinc (3.82 ± 0.10 mg/100 g), and sodium (123.76 ± 32.71 mg/100 g). Food intakes were lower in MP group compared to the others. According to organ histopathology results, animals fed with the diet have shown normal values, except rise in alkaline phosphatase (ALP) and creatine kinase (CK) in groups fed with meat powder. The results of organ function tests were all within the acceptable ranges and comparable with their counterpart control groups. However, some of the microbial contents of the meat powder were not within the recommended level. Conclusion: Dried meat powder has a higher amount of nutrients, which would be a potential recipe in complementary food preparation that can support to reduce child malnutrition. However, further studies need to be conducted on the sensory acceptability of formulated complementary foods containing dried meat powder; also, clinical trials are aimed at observing the effect of dried meat powder on child linear growth.

Health system response to COVID-19 among primary health care units in Ethiopia: A qualitative study.

INTRODUCTION: There was limited data on the experiences and roles of sub-national health systems in the response against COVID-19 in Ethiopia. This study explored how sub-national primary health care units and coordinating bodies in Ethiopia responded to COVID-19 during the first 6 months of pandemic. METHODS: We conducted a qualitative study with descriptive phenomenological design using 59 key informants that were purposively selected. The interviews included leaders across Ethiopia's 10 regions and 2 administrative cities. Data were collected using a semi-structured interview guide that was translated into a local language. The interviews were conducted in person or by phone. Coding and categorizing led to the development of themes and subthemes. Data were analyzed using thematic analysis. RESULTS: Local administrators across different levels took the lead in responding to COVID-19 by organizing multisectoral planning and monitoring committees at regional, zonal and woreda (district) levels. Health leaders reacted to the demand for an expanded workforce by reassigning health professionals to COVID-19 surveillance and case management activities, adding COVID-19-related responsibilities to their workloads, temporarily blocking leave, and hiring new staff on contractual basis. Training was prioritized for: rapid response teams, laboratory technicians, healthcare providers assigned to treatment centers where care was provided for patients with COVID-19, and health extension workers. COVID-19 supplies and equipment, particularly personal protective equipment, were difficult to obtain at the beginning of the pandemic. Health officials used a variety of means to equip and protect staff, but the quantity fell short of their needs. Local health structures used broadcast media, print materials, and house-to-house education to raise community awareness about COVID-19. Rapid response teams took the lead in case investigation, contact tracing, and sample collection. The care for mild cases was shifted to home-based isolation as the number of infections increased and space became limited. However, essential health services were neglected at the beginning of the pandemic while the intensity of local multisectoral response (sectoral engagement) declined as the pandemic progressed. CONCLUSIONS: Local government authorities and health systems across Ethiopia waged an early response to the pandemic, drawing on multisectoral support and directing human, material, and financial resources toward the effort. But, the intensity of the multisectoral response waned and essential services began suffering as the pandemic progressed. There is a need to learn from the pandemic and invest in the basics of the health system-health workers, supplies, equipment, and infrastructure-as well as coordination of interventions.

Determinants of vaccine acceptance, knowledge, attitude, and prevention practices against COVID-19 among governmental healthcare workers in Addis Ababa and Adama, Ethiopia: A cross-sectional study.

Background and Aims: COVID-19 vaccines are vital tools for infection prevention and control of the pandemic. However, coronavirus immunization requires acceptance among healthcare workforces and by the community. In Ethiopia, studies focused on determinants of vaccine acceptance, knowledge, attitude, and prevention practices (KAP) contrary to the novel coronavirus among healthcare staff are limited. Hence, closing this gap requires research. Methods: A cross-sectional study was conducted on 844 governmental healthcare workers. A stratified, simple random sampling technique was used to select the respondents. Data were collected using a structured questionnaire. Binary and multivariable logistic regression statistical models were used to analyze the data. Results: This study indicated that only 57.9% of the participants had good COVID-19 vaccine acceptance, meaning they took at least a dose of the vaccine themselves. We found that 65%, 60.9%, and 51.3% of the participants had good knowledge, prevention practices, and attitude against the pandemic. The novel coronavirus vaccine acceptance rate was 2.19 times more likely among females (adjusted odds ratio [AOR] = 2.19 with 95% confidence interval [CI]: 1.54-3.10) than among male participants. Further, respondents who did not report having any chronic diseases were 9.40 times higher to accept COVID-19 vaccines (AOR = 9.40 with 95% CI: 4.77, 18.53) than those who reported having a chronic condition. However, healthcare workers who had a habit of chewing khat at least once per week were 4% less likely to take the vaccine (AOR = 0.04 with 95% CI: 0.01, 0.32) than those who had no habit of chewing khat. Conclusion: Many core factors influencing COVID-19 vaccine acceptance were identified. A significant number of participants had poor vaccine acceptance, KAP against COVID-19. Therefore, the government should adopt urgent and effective public health measures, including public campaigns to enhance public trust in COVID-19 vaccines. In addition, continuous, timely, and practical training should be provided to healthcare workers.

Drivers of change in weight-for-height among children under 5 years of age in Ethiopia: Risk factors and data gaps to identify risk factors.

The prevention of wasting should be a public health priority as the global burden of acute malnutrition is still high. Gaps still exist in our understanding of context-specific risk factors and interventions that can be implemented to prevent acute malnutrition. We used data from the four rounds of the Ethiopia Demographic and Health Survey (2000-2016) to identify risk factors that have contributed to the change in weight-for-height z-score (WHZ) among children under 5 years of age. We performed a pooled linear regression analysis followed by a decomposition analysis to identify relevant risk factors and their relative contribution to the change in WHZ. Modest improvements in WHZ were seen between 2000 and 2016. The sharpest decrease in mean WHZ occurred from birth to 6 months of age. Perceived low weight at birth and recent diarrhoea predicted a decline in WHZ among children aged 0-5, 6-23 and 23-59 months. Less than 50% of the change in WHZ was accounted for by the change in risk factors included in our regression decomposition analysis. This finding highlights data gaps to identify context-specific wasting risk factors. The decline in the prevalence of recent diarrhoea (15% of the improvement), decline in low birth size (7%-9%), and an increase in wealth (15%-30%) were the main risk factors that accounted for the explained change in WHZ. Our findings emphasize the importance of interventions to reduce low birthweight, diarrhoea and interventions that address income inequities to prevent acute malnutrition.

Longitudinal profile of antibody response to SARS-CoV-2 in patients with COVID-19 in a setting from Sub-Saharan Africa: A prospective longitudinal study.

BACKGROUND: Serological testing for SARS-CoV-2 plays an important role for epidemiological studies, in aiding the diagnosis of COVID-19, and assess vaccine responses. Little is known on dynamics of SARS-CoV-2 serology in African settings. Here, we aimed to characterize the longitudinal antibody response profile to SARS-CoV-2 in Ethiopia. METHODS: In this prospective study, a total of 102 PCR-confirmed COVID-19 patients were enrolled. We obtained 802 plasma samples collected serially. SARS-CoV-2 antibodies were determined using four lateral flow immune-assays (LFIAs), and an electrochemiluminescent immunoassay. We determined longitudinal antibody response to SARS-CoV-2 as well as seroconversion dynamics. RESULTS: Serological positivity rate ranged between 12%-91%, depending on timing after symptom onset. There was no difference in positivity rate between severe and non-severe COVID-19 cases. The specificity ranged between 90%-97%. Agreement between different assays ranged between 84%-92%. The estimated positive predictive value (PPV) for IgM or IgG in a scenario with seroprevalence at 5% varies from 33% to 58%. Nonetheless, when the population seroprevalence increases to 25% and 50%, there is a corresponding increases in the estimated PPVs. The estimated negative-predictive value (NPV) in a low seroprevalence scenario (5%) is high (>99%). However, the estimated NPV in a high seroprevalence scenario (50%) for IgM or IgG is reduced significantly to 80% to 85%. Overall, 28/102 (27.5%) seroconverted by one or more assays tested, within a median time of 11 (IQR: 9-15) days post symptom onset. The median seroconversion time among symptomatic cases tended to be shorter when compared to asymptomatic patients [9 (IQR: 6-11) vs. 15 (IQR: 13-21) days; p = 0.002]. Overall, seroconversion reached 100% 5.5 weeks after the onset of symptoms. Notably, of the remaining 74 COVID-19 patients included in the cohort, 64 (62.8%) were positive for antibody at the time of enrollment, and 10 (9.8%) patients failed to mount a detectable antibody response by any of the assays tested during follow-up. CONCLUSIONS: Longitudinal assessment of antibody response in African COVID-19 patients revealed heterogeneous responses. This underscores the need for a comprehensive evaluation of seroassays before implementation. Factors associated with failure to seroconvert needs further research.

Association Between Dietary Fluoride and Calcium Intake of School-Age Children With Symptoms of Dental and Skeletal Fluorosis in Halaba, Southern Ethiopia.

Background: In the Ethiopian Rift Valley, ways to reduce the fluoride (F) burden from drinking water have been unsuccessful. Calcium (Ca) intake may mitigate fluorosis by binding with F ions and preventing absorption. The purpose of this study was to examine the association between Ca intake and proportion of fluorosis symptoms in school-age children in an area where F levels are known to be higher than WHO limit of 1.5 mg F/L water. Methods: A cross-sectional survey in the Halaba zone involved 135 eligible children aged 6-13 year who were recruited to have dental fluorosis assessed by a dentist and skeletal fluorosis assessed by a physiotherapist. Dietary Ca intake was determined by 24-h recall. Food items and samples from ground wells, taps and spring water were collected for F concentration. Associations were measured using bivariate logistic regression, adjusted for known confounders. Results: Water F averaged 5.09 mg/L. Total F intake was high, 10.57 mg/day, and Ca intake was low, 520 mg/day. Prevalence of dental fluorosis (from very mild to severe symptoms) was 73.1% for younger children (6-8 years) and 68.3 % for older children (9-13 years). The prevalence of children having symptoms of skeletal fluorosis ranged between 55.1 and 72.4%, with no apparent age difference. Dietary F intake of children was significantly positively associated with presence of dental fluorosis. Dietary Ca intake of children was significantly negatively associated with dental fluorosis. Higher than average dietary F intake significantly increased the odds of developing skeletal fluorosis symptoms when measured as inability to stretch and fold arms to touch back of head. Higher than average Ca intake was significantly associated with decreased odds of developing skeletal fluorosis measured as inability to bend body to touch the toes or floor. Conclusions: High dietary F, as expected, was associated with fluorosis in children. In the presence of higher Ca intake (>520 mg/day) some fluorosis symptoms were mitigated. There is a need to improve Ca intakes as all were below recommended levels, and this nutritional strategy may also reduce burden of excess F.

Caregivers Systematically Overestimate Their Child's Height-for-Age Relative to Other Children in Rural Ethiopia.

BACKGROUND: Stunting affects one-quarter of children <5 y of age, yet little is known about the accuracy of caregivers' perceptions regarding their child's linear growth. Most existing quantitative research on this topic has been conducted in high-income countries and has examined perceptions of children's weight rather than height. OBJECTIVES: In rural Ethiopia where linear growth faltering is highly prevalent, this study aimed to better understand how caregivers perceive their child's growth. The objectives of this analysis were to 1) assess caregivers' perceptions of their child's height; 2) investigate whether there is a discrepancy between a child's actual height and caregivers' perceptions of their child's height; and 3) examine the factors that influence discrepancies in estimating a child's height (secondary outcomes), including the role of the average height in the community (primary outcome). METHODS: We conducted a cross-sectional analysis using data from 808 woman caregivers of children ages 6-35 mo in the Oromia region of Ethiopia. We assessed caregivers' rankings (from 1 to 10) of their child's height relative to other children their age in their village. We then converted these rankings to z scores based on an age- and region-specific distribution in order to calculate their difference with the child's actual height-for-age z score and to determine the degree of overestimation. Lastly, we used multivariate log Poisson regressions to determine factors associated with overestimating a child's height. RESULTS: Forty-three percent of caregivers scored their child's height as the median; 37% overestimated their child's height relative to other children. Regression results showed caregivers who were poorer, and had children who were female, older, and stunted, were more likely to overestimate. CONCLUSIONS: Our findings suggest that caregivers of young children in Oromia systematically overestimated their children's height, which could adversely affect child health if these misperceptions translate to insufficient care-seeking behavior or feeding choices for children.

Association of Dietary Calcium Intake with Dental, Skeletal and Non-Skeletal Fluorosis among Women in the Ethiopian Rift Valley.

Fluorosis is a major public health problem in the Rift Valley of Ethiopia. Low calcium (Ca) intake may worsen fluorosis symptoms. We assessed the occurrence of fluorosis symptoms among women living in high-fluoride (F) communities in South Ethiopia and their associations with dietary Ca intake. Women (n = 270) from two villages provided clinical and questionnaire data. Dental fluorosis examination was done using Dean's Index, and skeletal and non-skeletal fluorosis assessment was carried out using physical tests and clinical symptoms. Daily Ca intake was estimated by a food frequency questionnaire. Food, drinking water and beverage samples were analyzed for F level. Many subjects (56.3%) exhibited dental fluorosis. One-third of the women were unable to perform the physical exercises indicative of skeletal fluorosis; about half had ≥2 symptoms of skeletal/non-skeletal fluorosis. The average F level in drinking water sources was ~5 mg/L. The F content in staple food samples varied from 0.8-13.6 mg/kg. Average Ca intake was 406 ± 97 mg/day. Women having ≤400 mg/day Ca intake had ~3 times greater odds of developing skeletal rigidity with joint pains [AOR = 2.8, 95%CI: 1.6, 5.0] and muscular weakness [AOR = 2.9, 95%CI: 1.3, 6.3] compared to those with higher intakes. No association of calcium intake was seen with dental fluorosis. As low dietary Ca intake was associated with symptoms related to skeletal and non-skeletal fluorosis, this warrants nutritional intervention on calcium intakes in this setting.

Progress in Water, Sanitation and Hygiene (WASH) coverage and potential contribution to the decline in diarrhea and stunting in Ethiopia.

Inadequate safe water supply and poor sanitation and hygiene continue to be important risk factors for diarrhoea and stunting globally. We used data from the four rounds of the Ethiopian Demographic and Health Survey and applied the new World Health Organization (WHO)/UNICEF Joint Monitoring Program (JMP) service standards to assess progress in water, sanitation and hygiene (WASH) coverage between 2000 and 2016. We also performed an age-disaggregated pooled linear probability regression analysis followed by a decomposition analysis to determine whether changes in WASH practices have contributed to the changing prevalence of diarrhoea and stunting in children under 5 years of age. We observed a significant increase in the coverage of safe drinking water and adequate sanitation facilities over the period. At the national level, the use of a basic water source increased from 18% in 2000 to 50% in 2016. Open defecation declined from 82% to 32% over the same period. However, in 2016, only 6% of households had access to a basic sanitation facility, and 40% of households had no handwashing facilities. The reduction in surface water use between 2000 and 2016 explained 6% of the decline in diarrhoea observed among children aged 0-5 months. In children aged 6-59 months, between 7% and 9% of the reduction in stunting were attributable to the reduction in open defecation over this period. Despite progress, improvements are still needed to increase basic WASH coverage in Ethiopia. Our findings showed that improvements in water and sanitation only modestly explained reductions in diarrhoea and stunting.

Prognostic factors and outcomes of COVID-19 cases in Ethiopia: multi-center cohort study protocol.

BACKGROUND: The coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus (SARS-CoV-2) and became pandemic after emerging in Wuhan, China, in December 2019. Several studies have been conducted to understand the key features of COVID-19 and its public health impact. However, the prognostic factors of COVID-19 are not well studied in the African setting. In this study, we aim to determine the epidemiological and clinical features of COVID-19 cases, immunological and virological courses, interaction with nutritional status, and response to treatment for COVID-19 patients in Ethiopia. METHODS: A multi-center cohort study design will be performed. Patients with confirmed COVID-19 infection admitted to selected treatment centers will be enrolled irrespective of their symptoms and followed-up for 12 months. Baseline epidemiological, clinical, laboratory and imaging data will be collected from treatment records, interviews, physical measurements, and biological samples. Follow-up data collection involves treatment and prognostic outcomes to be measured using different biomarkers and clinical parameters. Data collection will be done electronically using the Open Data Kit (ODK) software package and then exported to STATA/SPSS for analysis. Both descriptive and multivariable analyses will be performed to assess the independent determinants of the treatment outcome and prognosis to generate relevant information for informed prevention and case management. The primary outcomes of this study are death/survival and viral shedding. Secondary outcomes include epidemiological characteristics, clinical features, genetic frequency shifts (genotypic variations), and nutritional status. DISCUSSION: This is the first large prospective cohort study of patients in hospitals with COVID-19 in Ethiopia. The results will enable us to better understand the epidemiology of SARS-CoV-2 in Africa. This study will also provide useful information for effective public health measures and future pandemic preparedness and in response to outbreaks. It will also support policymakers in managing the epidemic based on scientific evidence. TRIAL REGISTRATION: The Protocol prospectively registered in ClinicalTrials.gov (NCT04584424) on 30 October, 2020.
