Early childhood growth is associated with cognitive function. However, the independent associations of fat mass (FM) and fat-free mass (FFM) with cognitive function are not well understood. We investigated associations of FM and FFM at birth and 0-5 years accretion with cognitive function at 10 years. Healthy term newborns were enrolled in this cohort. FM and FFM were measured at birth, 1.5, 2.5, 3.5, 4.5, 6 months, 4 and 5 years. Cognitive function was assessed using Peabody Picture Vocabulary Test (PPVT) at 10 years. FM and FFM accretion were computed using statistically independent conditional accretion from 0-3 months, 3-6 months, 6 months-4 years, and 4-5 years. Multiple linear regression was used to assess associations. At the 10-year follow-up, we assessed 318 children with mean (SD) age of 9.8 (1.0) years. A 1 SD higher birth FFM was associated with a 0.14 SD (95% CI: 0.01, 0.28) higher PPVT at 10 years. FFM accretion from 0-3 and 3-6 months was associated with PPVT at 10 year, β = 0.5 SD (95% CI: 0.08, 0.93) and β = -0.48 SD (95% CI: -0.90, -0.07, respectively. FFM accretion after 6 months showed no association with PPVT. Neither FM at birth nor 0-5 years accretion showed association with PPVT. Overall, birth FFM, but not FM was associated with cognitive function at 10 years, while the association of FFM accretion and cognitive function varied across distinct developmental stages in infancy. The mechanisms underlying this varying association between body composition and cognitive function need further investigation.

Selenium (Se) deficiency among populations in Ethiopia is consistent with low concentrations of Se in soil and crops that could be addressed partly by Se-enriched fertilisers. This study examines the disease burden of Se deficiency in Ethiopia and evaluates the cost-effectiveness of Se agronomic biofortification. A disability-adjusted life years (DALY) framework was used, considering goiter, anaemia, and cognitive dysfunction among children and women. The potential efficiency of Se agronomic biofortification was calculated from baseline crop composition and response to Se fertilisers based on an application of 10 g/ha Se fertiliser under optimistic and pessimistic scenarios. The calculated cost per DALY was compared against gross domestic product (GDP; below 1–3 times national GDP) to consider as a cost-effective intervention. The existing national food basket supplies a total of 28·2 µg of Se for adults and 11·3 µg of Se for children, where the risk of inadequate dietary Se reaches 99·1 %–100 %. Cereals account for 61 % of the dietary Se supply. Human Se deficiency contributes to 0·164 million DALYs among children and women. Hence, 52 %, 43 %, and 5 % of the DALYs lost are attributed to anaemia, goiter, and cognitive dysfunction, respectively. Application of Se fertilisers to soils could avert an estimated 21·2–67·1 %, 26·6–67·5 % and 19·9–66·1 % of DALY via maize, teff and wheat at a cost of US$129·6–226·0, US$149·6–209·1 and US$99·3–181·6, respectively. Soil Se fertilisation of cereals could therefore be a cost-effective strategy to help alleviate Se deficiency in Ethiopia, with precedents in Finland.

Globally, each year 1.3 million neonates acquire human immunodeficiency virus during pregnancy, labour, and breastfeeding time. Replacing breastfeeding with recommended safe infant feeding practices significantly reduces the risk of transmission, nearly eliminating it. This study aimed to assess Human immunodeficiency virus exposed child feeding among 314 mothers with infants under 24 months old. Participants were selected using a systematic random sampling technique, and data were collected through a semi-structured questionnaire. Bivariable and multivariable logistic regression analyses employed to identify determinants for safe infant feeding. During interviews, the mean age of women was 32.35 years (standard deviation±4.5), and infants were 10.8(±3.951) months. The overall safe infant feeding was 67.2% (95% CI: 61.7, 72.9), with a mean knowledge score. By the study’s end, 9 infants (2.89%) were confirmed to be infected with virus based on dried blood sample test. Maternal promoting factors for safe infant practice included infant age 25–35 years (adjusted odd ratio (aOR) =2.9) completing high school education (adjusted odd ratio = 9.2), having a good knowledge score for infant feeding (adjusted odd ratio = 8.2), and urban residency (adjusted odd ratio = 2.2). On the other hand, being married made it 83% less likely for safe infant feeding practices (adjusted odd ratio = 0.17) compared to those never in a union. Two in three mothers practiced safe infant feeding for their HIV-exposed infants, with a mean knowledge score of 70.3%. Therefore, healthcare providers give accurate information and counselling services to make informed decisions about infant safe feeding.

The aim of this study is to assess nutritional status and associated factors among infants and young children aged 6–23 months in Yeka sub-city, Ethiopia, 2021. An institution-based cross-sectional study was conducted in selected health centres found in the Yeka sub-city from May 2021 to July 2021. In total, 396 systematically selected infants and young children aged 6–23 months attended the selected health centres were included in the study. Data were collected by using a structured questionnaire and anthropometric measurements. A multinomial logistic regression model was used.

The overall magnitude of undernutrition and overnutrition among infants and young children were 24.7% and 5.5%, respectively. Dietary diversity score (DDS) ((adjusted odd ratio (AOR) = 5.65; 95% CI = 2.301, 10.87; P value = 0.003), minimum meal frequency (MMF) (AOR = 5.435; 95% CI = 2.097, 11.09; P value = 0.0052), and diarrhoea (AOR = 2.52; 95% CI = 1.007, 6.310; P value = 0.002) were statistically significantly associated factors for nutritional status among infants and young children. Malnutrition (undernutrition and overnutrition) is a public health problem among infants and young children in Yeka sub-city, Ethiopia. DDS, MMF, and diarrhoeal disease were associated with higher odds of undernutrition.

Addis Ababa initiated a universal Home-Grown School Feeding Program (HGSFP) in February 2019 to address hunger and improve the educational outcomes of schoolchildren. This study aimed to document the perceived benefits and challenges of the HGSFP in Addis Ababa, where such information was lacking. In May 2023, a qualitative phenomenological study was conducted to collect data from 20 schools participating in the HGSFP. Data were collected through key informant interviews and focus group discussions (FGDs) involving 98 purposively selected participants. The study encompassed 48 student mothers in 5 FGDs, 20 student interviews, 20 school principals, and 10 experts from the Ministry of Education, Sub-cities, and the School Feeding Agency for in-depth interviews. Data collected in the local language were transcribed, translated into English, and thematically analysed using ATLAS-TI software. The study’s findings unveiled the transformative impact of the HGSFP in Addis Ababa, Ethiopia. It demonstrated remarkable improvements in attendance, concentration, academic performance, reduced dropout rates, financial relief, enhanced behaviour, and a safer learning environment. However, urgent measures are imperative to tackle pressing challenges such as underpaid kitchen workers, operational issues, reduced reading time, rising food costs, limited market access, inadequate infrastructure, and growing dependency. To ensure the enduring sustainability of HGSFP, addressing challenges like workload reduction, kitchen infrastructure enhancement, government guideline implementation, promoting self-reliance, overcoming budget limitations, and addressing school gardening obstacles is vital.

Maternal knowledge and attitudes towards nutrition are essential for achieving healthy dietary behaviours for a positive pregnancy outcome. Therefore, this study aimed to assess the level and determinants of knowledge and attitudes towards nutrition among pregnant women in the Minjar Shenkora district, Ethiopia. Institution-based cross-sectional study was conducted between June and August 2021 among 334 pregnant women who were selected using a systematic random sampling technique. Data were collected using a semi-structured questionnaire and analysed using SPSS version 21. Bivariate and multivariate logistic regression analyses were used to identify the determinants of nutritional knowledge and attitudes. P < 0.05, with a 95% CI was used to declare statistical significance. Overall, 69.2% and 44.0% of the pregnant women were not knowledgeable and had an unfavourable attitude toward nutrition, respectively. The educational status of pregnant women (P < 0.01) and access to nutritional information (P < 0.01) were significantly associated with nutritional knowledge, while the educational status of pregnant women (P < 0.01) was associated with nutritional attitude. Respondents’ knowledge of and attitudes toward nutrition were low. Pregnant women’s educational levels and access to nutritional information are strongly related to their nutritional knowledge. Likewise, the educational status of the pregnant women was significantly associated with their nutritional attitudes. Therefore, education and counselling on maternal nutrition are needed to improve healthy maternal nutrition tips in the study area.

Elections in divided societies and in countries undergoing political transitions are precarious events. Hastened democratisation may ignite inter-communal antagonism and mobilise voters for conflict. Sub-national elections are even more prone to challenge national policies to defend regional autonomy and self-determination. The relationship between the Tigray Peoples' Liberation Front (TPLF) and the Ethiopian Federal government had been deteriorating since the coming to power of Prime Minister Abiy Ahmed in 2018. It was formally breached in September 2020 when the TPLF insisted on organising a separate regional election in Tigray in defiance of the federal government's decision to postpone national elections due to the outbreak of the COVID-19 pandemic, leading to one of Africa's most devastating civil wars in modern times. In the pursuit of democratic legitimacy, and conversely consciously framing the federal government as non-democratic, the TPLF ‘weaponised’ the election. This article analyses the process leading up to the decision to conduct separate elections in Tigray, its conduct and result. The analysis demonstrates how elections and the contestation to claim a democratic legitimacy in transition countries may contribute to a politics of violence, ultimately leading to war.

Tetraploid wheat species from Ethiopia hold ample genetic variation, which could provide a source for improvement of wheat. A total of 196 Ethiopian tetraploid wheat (Triticum turgidum spp.) accessions, including 174 landraces and 22 improved cultivars, were evaluated at Sinana and Debrezeit to assess morphological variation, genetic advance, heritability and correlation based on 11 phenotypic traits. Except for spike length, highly significant variation (P < 0.001) among genotypes for all traits was observed. The observed mean and range values of the phenotypic traits revealed high variability in the accessions. Phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) values were high for grain yield, biomass yield and harvest index. Seed yield showed highly significant (P < 0.001) negative correlation with days to booting and days to maturity and positive correlation with all traits. The estimates of heritability (H2) for grain yield and the number of spikelets per spike respectively ranged from 41.78 to 84.62%. The genetic advance as a percentage of mean was low for the number of seeds per spikelet, days to booting and days to maturity; intermediate for plant height, thousand kernel weight and spike length and high for the number of spikelets per spike, the number of effective tillers per plant, grain yield, biomass yield and harvest index, respectively. The number of spikelets per spike gave a high value of genetic advance and heritability implying high genetic gain from its selection.

Land degradation and declining productivity in the Ethiopian Highlands are primarily caused by soil fertility decline due to erosion, nutrient depletion, and soil acidity. An integrated soil fertility management (ISFM) project operating over a six-year period aimed to combat this and boost yields through participatory demonstrations. Despite high levels of yield variability expected from a farmer-managed observational study over a wide area, results show that crop yields increased with increased use of ISFM. Detailed statistical analysis using multiple linear regression models explained the contribution of individual practices. Use of improved varieties and line-seeding rather than broadcasting were consistently and highly significant. The contribution of inorganic blended fertiliser was less clear, probably due to low soil organic matter and use on acidic soils, although response to nitrogen was highly significant. The contribution of organic fertilisers was less than expected, possibly due to soil disturbance from farmer practices of multiple ploughing. Responses to crop residue management and agroforestry practices were significant on most crops reflecting their importance in improving soil water management, soil organic matter and recycling nutrients. Response to lime application on acid soils was highly significant confirming the importance of correcting acidity. Unexplained differences are attributed to the additive effects of using several ISFM treatments as well as unrecorded beneficial farmer management practices. It can be concluded that ISFM can play an essential role in improving productivity, addressing food insecurity and the challenges of climate change. Further expansion will require advocacy, awareness-raising, field-level extension and involvement of the private sector.
