Background Remaining underweight during Tuberculosis (TB) treatment is associated with a higher risk of unsuccessful TB treatment outcomes and relapse. Previous studies conducted in Ethiopia found that bodyweight not adjusted for height at the start of treatment is associated with poor treatment outcomes. However, the association of body mass index (BMI) and weight change during treatment with treatment outcomes has not been studied. We aimed to investigate the association of BMI at the time of diagnosis and after two months of treatment and TB treatment outcomes. Methods Using an ambi-directional cohort study design (retrospective and prospective), a total of 456 participants were enrolled among 30 randomly selected public health centers residing within six sub-cities of Addis Ababa, Ethiopia. Data were collected using medical chart abstraction and face to face interviews. We compared TB treatment outcomes in persons with a body mass index (BMI) <18.5kg/m2 (underweight) versus persons with BMI ≥18.5kg/m2 (normal or overweight) at treatment initiation and after two months of treatment. Treatment was classified as successful in persons who were free of symptoms and had a negative sputum smear for acid-fast bacilli at the end of the 6-month treatment course. We analysed outcomes using univariable and multivariable logistic regression with 95% CI and p value< 0.05. Results Of enrolled study participants, 184 (40.4%) were underweight and 272 (59.6%) were normal or overweight. Body mass index (BMI ≥18.5kg/m2) at the start and second month of treatment were independent predictors for successful treatment outcome (AOR = 2.15; 95% CI: 1.05, 4.39) and (AOR = 3.55; 95% CI: 1.29, 9.73), respectively. The probability of treatment success among patients with BMI≥18.5kg/m2 at the start and second month of treatment was 92.9% and 97.1%, respectively versus 86.5% and 91.7% in patients with BMI<18.5kg/m2. Bodyweight not adjusted for height and change in the bodyweight after the second and sixth months of treatment were not significantly associated with treatment success. Conclusion In persons treated for TB disease, being underweight at baseline and after two months of treatment was a predictor for unsuccessful treatment outcomes. Nutritional assessment, counselling, and management are important components of TB treatment programs with the potential to improve treatment outcomes.

Background Despite the universal iodization of salt in Ethiopia, iodine deficiency disorder remains a major public health problem and continued to affect a large segment of the population. It is thus essential to assess factors contributing to the unacceptably high endemic goiter rate in the country and avail evidence for further additional interventions. In line with this, we examined the association of dietary pattern and iodine deficiency among school-age children in Ethiopia. Method We conducted a school-based cross-sectional study among 767 children aged 6 to 12 in southwest Ethiopia. We collected socio-demographic and other important health related information using a pre-tested structured questionnaire through the interview. Dietary pattern of children was measured using modified Hellen Keller’s food frequency questionnaire. We measured iodine deficiency using urinary iodine concentration level and total goiter rate, according to the World Health Organization threshold criteria. We used a multivariate linear regression model to identify dietary and sociodemographic factors that affect urinary iodine level among children. Result Out of the 767 children included in the study, 12% and 4% of children have grade 1 and grade 2 goiter respectively, making the total goiter rate 16%. While the prevalence of iodine deficiency based on urinary iodine concentration is 58.8% of which 13.7% had severe, 18.6% had moderate and 26.5% had mild form. The proportion of children who consumed godere/taro root/, banana, corn, Abyssinian cabbage, and potato, respectively at daily basis 57.8%, 53.1%, 37.9%, and 31.2%, respectively. Age (β = -0.7, 95%CI = -1.1, -0.4), sex (β = -22.3, 95%CI = -33.8, -10.8), consumption of taro root (β = -27.4, 95%CI = -22.9, -31.8), cabbage (β = -11.7, 95%CI = -5.7, -17.6), Abyssinian cabbage (β = 12.4, 95%CI = 6.7, 18.2), and banana (β = 5.6, 95%CI = 0.01, 11.2) significantly associated with urinary iodine level. Conclusion Iodine deficiency remains an important public health problem in southwest Ethiopia. Over-consumption of goitrogenic foods and under-consumption of iodine-rich foods were prevalent and associated with lower urinary iodine level. Therefore, dietary counseling apart from universal salt iodization is recommended.

Birthweight continues to be the leading infant health indicator and the main focus of infant health policy. Low birthweight babies are at a higher risk of mortality and morbidity in most low-income countries. However, the physical activity level of pregnant women and its association with low birthweight is not well studied in Ethiopia. To address the above gap, we aimed to examine the maternal physical activity level and other characteristics during the third trimester and its association with birthweight at term in South Ethiopia. A community-based prospective cohort study was conducted among 247 randomly selected women in their third trimester of pregnancy. We measured the physical activity level using the Global Physical Activity Questionnaire, which included the type and level of various categories of activities. Anthropometric measurements of mothers were taken following standard procedures, and birthweight was recorded within 72 hours of delivery. To identify the effect of physical activity level and other maternal characteristics on low birthweight, we performed a multivariable logistic regression analysis. Overall, 111 (47.2%) mothers were engaged in vigorous physical activities during third trimester. The incidence of low birthweight was 21.6% and 9.68% among newborns of mothers who engaged in vigorous and moderate or low physical activity, respectively. The incidence of low birthweight at term was significantly associated with vigorous physical activity [adjusted odds ratio (AOR) = 2.48; 95% confidence interval (CI): 1.01–6.09], prolonged standing [AOR = 3.37; 95% CI: 1.14–9.93], and squatting [AOR = 2.61; 95% CI: 1.04–6.54)] during the third trimester of pregnancy. The vast majority of pregnant women were engaged in vigorous physical activities in their third trimester. Engagement in vigorous physical activity, standing for longer hours, and squatting were the major contributors to low birthweight at term. Hence, focused counseling should be conducted to reduce vigorous physical activity, standing, and squatting during the third trimester among pregnant women.

Background: Understanding the national burden and trend of micronutrient deficiencies helps to guide effective intervention strategies under various circumstances. There is, however, a lack of evidence on trends, age-and sex-specific variations in Ethiopia. Objective: This study aimed to provide evidence on the trends of common micronutrient deficiencies including, dietary iron, iodine, vitamin A and other nutritional deficiencies in Ethiopia, from 1990 to 2017, using findings from the Global Burden of Disease study. Method: We used estimates from the GBD 2017 study to report the incidence, prevalence and disability-adjusted life years of micronutrient deficiencies in Ethiopia from 1990 to 2017. All estimates, both crude counts, as well as all-age and age-standardized rates per 100,000 population, are accompanied by 95% uncertainty intervals (UIs). We summarized the age-and sex-specific patterns and we compared the burden with the sub-Saharan Africa and global estimate. Results: From 1990 to 2017, the age-standardized prevalence rate of dietary iron, vitamin A and iodine deficiency decreased by 20.1%, 16.7%, and 91.6%, respectively. However, MNDs still account for a large number of DALYs in the country. In 2017, the all-age total DALYs due to dietary iron deficiency were estimated to be 448.4 thousand [95% UI: 298.9-640.7], accounting for 1.18% of the total DALYs. Similarly, the all-age total DALYs due to vitamin A deficiency were 397.8 thousand [256.1-589.2]. The total DALYs due to iodine deficiency were estimated to be 89.6 thousand [48.3-155.4]. Conclusions: Micronutrient deficiencies and associated morbidity and mortality are still high in Ethiopia compared with the sub-Saharan and global estimate. Adolescent and early adult females and children aged under-five are disproportionately affected segments of the population. Therefore, in collaboration with other sectors, the National Nutrition Program needs to place greater emphasis upon improving accessibility and utilization of nutrient-rich foods and supplementation, particularly for vulnerable groups of the population.

Malaria is the most significant human parasitic disease and remains a major cause of morbidity and mortality worldwide, particularly in developing countries. It affects children below the age of 5 years and pregnant women more severely. Globally, an estimated 3.3 billion people were at risk of malaria, with ~80% of cases and 90% of deaths in 2011 occurring in the World Health Organization (WHO) African region. [1] Hunger and malnutrition also remain among the most devastating problems facing the majority of the world's poor and needy, and continue to dominate the health of the world's poorest nations. The United Nations Food and Agriculture Organization estimates that nearly 870 million people, or one in eight people globally, suffered from chronic undernourishment between 2010 and 2012. [2] Nearly 30% of the population of the developing world, including infants, children, adolescents, adults and older persons, are currently suffering from one or more of the multiple forms of malnutrition. [3] Based on the 2013 United Nations Children's Fund report, 38% of children below the age of 5 years suffer from chronic malnutrition or stunting in sub-Saharan Africa, with malaria and undernutrition being the two major causes of childhood mortality. [3] In Ethiopia, both undernutrition and malaria are major public health problems, with an estimate of 55.7 million people (68% of the population) at risk for malaria, and nearly 80% of the existing 736 districts malaria endemic. [4] In 2009/2010, malaria was the leading cause of outpatient visits and health facility admissions, accounting for 14% of outpatient visits and 9% of admissions. [4] Chronic malnutrition prevalence reported for the same period, manifesting in the form of stunting and underweight, was 44% and 29%, respectively, indicating the burden of the problem in the country. [5] The synergy of malnutrition and infections is widely documented elsewhere, [6,7] though the relationship between malnutrition and malaria is conflicting. [8-13] This presents a challenge in attempting to control the issue. This study was conducted to investigate the association between chronic malnutrition and malaria, and provide necessary information to develop effective strategies for the control of malaria and prevention of malnutrition. Methods Study design and setting An institution-based case-control study was conducted to assess the association of undernutrition and malaria among children in Bahir-Dar special zone, which has 10 health centres (3 rural and 7 urban). The zone is situated on the southern shore of Lake Tana, 564 km northwest of Addis Ababa, with an elevation of 1 840 m above sea level. The zone is heterogeneous with various ethnic populations and malaria is endemic with seasonal transmission, which makes the site ideal for investigating the association of malaria and undernutrition. From the available health facilities at the time of the study, two rural and four urban facilities were purposively selected for our assessment.
