Care groups in an integrated nutrition education intervention improved infant growth among South Sudanese refugees in Uganda's West Nile post-emergency settlements: A cluster randomized trial.

OBJECTIVE: This study examined the effects of a peer-led integrated nutrition education intervention with maternal social support using Care Groups on infant growth among South Sudanese refugees in Uganda. METHODS: A community-based cluster-randomized trial (RCT) was conducted among 390 pregnant women (third trimester). Two intervention study arms were Mothers-only(n = 131) and Parents-combined (n = 142) with a Control (n = 117). WHO infant growth standards defined length-for-age z-scores (LAZ) for stunting, weight-for-age z-scores (WAZ) for underweight and weight-for-length z-scores (WLZ) for wasting. The Medical Outcomes Study (MOS) social support index was a proxy measure for social support. A split-plot ANOVA tested the interaction effects of social support, intervention, and time on infant growth after adjusting for covariates. Further, pairwise comparisons explained mean differences in infant growth among the study arms. RESULTS: The mean infant birth weight was 3.1 ± 0.5 kg. Over the study period, infant stunting was most prevalent in the Control (≥ 14%) compared to Mothers-only (< 9.5%) and Parents-combined (< 7.4%) arms. There were significant interaction effects of the Care Group intervention and social support by time on infant mean LAZ (F (6, 560) = 28.91, p < 0.001), WAZ (F (5.8, 539.4) = 12.70, p = < 0.001) and WLZ (F (5.3, 492.5) = 3.38, p = 0.004). Simple main effects by the end of the study showed that the intervention improved infant mean LAZ (Mothers-only vs. Control (mean difference, MD) = 2.05, p < 0.001; Parents-combined vs. Control, MD = 2.00, p < 0.001) and WAZ (Mothers-only vs. Control, MD = 1.27, p < 0.001; Parents-combined vs. Control, MD = 1.28, p < 0.001). CONCLUSION: Maternal social support with an integrated nutrition education intervention significantly improved infant stunting and underweight. Nutrition-sensitive approaches focused on reducing child undernutrition among post-emergency refugees may benefit from using Care Groups in programs.

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.

Home stimulation, development, and nutritional status of children under 2 years of age in the highlands of Madagascar.

BACKGROUND: The Vakinankaratra region of Madagascar has a high burden of child undernutrition which, in addition to poor psychosocial stimulation, is a strong risk factor of poor child development. However, there are limited studies evaluating the relations between developmental deficits, child nutrition outcomes, and home stimulation in the region. The purpose of this study was to assess the development of children aged 11-13 months in relation to their nutritional status and to examine parental home stimulation attitudes and practices in the Vakinankaratra region. METHODS: Cognitive (n = 36), language (n = 36), motor (n = 36), and socioemotional (n = 76) development were assessed using the Bayley Scales of Infant and Toddler Development III. Household stimulation environment was evaluated using the family care indicators survey. Stunting (length-for-age z-score < - 2) and underweight (weight-for-age z-score < - 2) were determined using the 2006 WHO growth standards. Perceptions of and barriers to greater home stimulation for children were collected using focus group discussions among parents and in-depth interviews with community nutrition agents. RESULTS: Almost all mothers reported that parent-child interaction with talk and play was very important. Alarmingly high stunting rates (> 69%) were observed in this subsample. Limited time and tiredness were the major barriers to home stimulation mentioned by parents and confirmed by key informants. Children had a very limited variety of play materials, and most of the mothers used household objects (75%) and materials from outside the house (71%) as children's toys. Composite cognitive [mean (SD): 60 (10.3)], motor [61.9 (13.4)], language [62 (13.2)], and socioemotional [85.1 (17.9]) scores were low. Fine motor, cognitive, and receptive and expressive language scores were correlated [0.4 < r < 0.7, p < 0.05]. CONCLUSIONS: The very high stunting rates and very low performance on cognitive, motor, language, and socioemotional development assessments of children in the Vakinankaratra region require urgent attention.

A Peer-Led Integrated Nutrition Education Intervention through Care Groups Improved Complementary Feeding of Infants in Postemergency Settlements in the West-Nile Region in Uganda: A Cluster Randomized Trial.

Background: Complementary feeding of infants in refugee settlements remains inadequate. Furthermore, there has been limited evaluation of interventions addressing these nutrition challenges. Objective: This study examined the effects of a peer-led integrated nutrition education intervention on infant complementary feeding by South Sudanese refugee mothers in the West-Nile region in Uganda. Methods: A community-based randomized trial enrolled 390 pregnant women (during third trimester) as the baseline. Two arms [mothers-only and parents-combined (both mothers and fathers)] comprised treatments with a control. Infant feeding was assessed using WHO and UNICEF guidelines. Data were collected at Midline-II and Endline. The medical outcomes study (MOS) social support index was used to measure social support. An overall mean score of >4 was considered optimal social support, a score of ≤2 was none or little support. Adjusted multivariable logistic regression models determined the effects of the intervention on infant complementary feeding. Results: At the end of the study, infant complementary feeding improved significantly in both mothers-only and parents-combined arms. There was a positive effect on the introduction of solid, semisolid, and soft foods (ISSSF) in the mothers-only arm at both Midline-II {adjusted odds ratio (AOR) = 4.0]} and Endline (AOR = 3.8). Likewise, ISSSF was better for the parents-combined arm at both Midline-II (AOR = 4.5) and Endline (AOR = 3.4). Minimum dietary diversity (MDD) was significantly better at the Endline for the parents-combined arm (AOR = 3.0). Minimum acceptable diet (MAD) was significantly better at Endline for both mothers-only (AOR = 2.3) and parents-combined arms (AOR = 2.7). Infant consumption of eggs and flesh foods (EFF) was improved only in the parents-combined arm at both Midline-II (AOR = 3.3) and Endline (AOR = 2.4). Higher maternal social support was associated with better infant MDD (AOR = 3.3), MAD (AOR = 3.6), and EFF (AOR = 4.7). Conclusion: Engaging both fathers and mothers in care groups benefited complementary feeding of infants. Overall, this peer-led integrated nutrition education intervention through care groups improved infant complementary feeding in the West-Nile postemergency settlements in Uganda.This trial was registered at clinicaltrials.gov as NCT05584969.

Breastfeeding among South Sudanese refugees in protracted settlements in Adjumani district, Uganda: facilitators and barriers.

BACKGROUND: Evidence suggests that forced migration and refugee status may adversely impact mothers' breastfeeding choices. Furthermore, suboptimal breastfeeding practices have been reported among vulnerable populations including those living in refugee settlements. Therefore, this study investigated the barriers and facilitators of breastfeeding in protracted settlements in Adjumani district, in the West Nile region in Uganda. METHODS: This study was conducted among refugees living in protracted settlements located in Uganda in July 2019. Participants, originally from South Sudan, included mothers (n = 63) and fathers (n = 32) of children less than 24 months of age. Agojo, Ayilo-I, and Nyumanzi were randomly selected among the 17 refugee settlements in Adjumani. Participants formed a total of six focus group discussions (FGDs); four FGDs for mothers and two FGDs for fathers. Each FGD consisted of 15-16 participants. Data were transcribed verbatim and back-translated into English. Thematic analysis was used and data were analyzed using NVivo, v. 12. RESULTS: Facilitators of breastfeeding included knowledge of breastfeeding benefits, support from husband/father, support from the community, and support from non-governmental organizations. Mothers and fathers noted that breastfeeding protected children from diseases and breastfed children grew well. Fathers, the community, and organizations provided material support for breastfeeding mothers. Four themes were identified as barriers to breastfeeding: physical, socioeconomic, knowledge, and psychosocial. Mothers and fathers described physical barriers such as mothers stop breastfeeding when they are sick or they feel they are not producing enough breastmilk. Mothers reported that working or educated mothers may use other milk to feed their infant. Some mothers and fathers believed infants under six months needed more than breastmilk. Fathers described psychosocial barriers such as mothers' fear of pain during breastfeeding and maternal mental health issues. CONCLUSION: Interventions and policies that aim to improve breastfeeding in protracted settlements should consider addressing the barriers to breastfeeding at each level: physical, socioeconomic, knowledge, and psychosocial. Involving and encouraging support from husbands/fathers, relatives, and the community may increase adherence to breastfeeding recommendations.

Suboptimal feeding practices and impaired growth among children in largely food insecure areas of north Wollo, Ethiopia.

In Ethiopia, information is limited about energy and micronutrient intakes from complementary foods consumed by children in Productive Safety Net Program districts. Therefore, we assessed feeding practices and intakes of energy and selected micronutrients from complementary foods of children aged 6-23 months in a food insecure rural area of Ethiopia. Energy and micronutrient intakes were estimated from multiple-pass 24 h recall. Data were collected using a structured questionnaire. Only 1⋅9 % of children in the age range 6-8 months met recommended minimum dietary diversity of ≥5 food groups; this value slightly increased to 4 and 10⋅1 % in the older age groups (9-11 months and 12-23 months, respectively). Overwhelmingly, none of the children (9-11 months) did get the minimum acceptable diet (Children receiving minimum acceptable diet were 4 and 2⋅6 % in 6-8 months and 12-23 months, respectively). The overall prevalence of stunting was 34 % in younger children (6-8 months) and 51 % in older children aged 12-23 months. Median energy and selected micronutrient intakes from complementary foods were below corresponding WHO recommendations assuming average breast-milk amount and composition. The worst shortfalls were for vitamins A and C and for Ca. In contrast, median iron, protein and niacin intakes and densities were above the WHO recommendation. Caretakers and community leaders in the study setting need nutrition education on IYCF-related practices and on the importance of men's involvement in IYCF. Ensuring the accessibility and affordability of animal source foods (ASFs), fruits and vegetables, and feasible complementary foods is critical to address the quality of complementary feedings. This can be achieved through promoting nutrition-sensitive agriculture such as poultry and home gardening in this setting.

Successes and challenges of the Home-grown School Feeding Program in Sidama Region, Southern Ethiopia: a qualitative study.

The Home-grown School Feeding Program (HG-SFP) is a model designed to provide school meals to students using foods sourced from local markets. HG-SFP recently has been incorporated as one of the strategies of educational development in Ethiopia aiming to address hunger and food insecurity problems of school children. Yet, evaluation of the successes and challenges of the program has been limited evaluated. The purpose of the present study was to explore the successes and challenges of the SFP in Sidama Region, Southern Ethiopia. This exploratory qualitative study collected data from eight schools targeted for HG-SFP through key informant interviews and focus group discussions (FGDs). A total of sixteen FGDs and twenty-one in-depth interviews were conducted. Purposive sampling was used to include study participants based on their potential relevance in delivering in-depth information. The findings of the present study showed that HG-SFP was successful in improving class attendance and academic performance of school children. In addition, the program had a contribution in saving the parents' money and time as a result of the food provided. With regard to SFP challenges, lack of permanent clean water provision, delay in ration delivery, poor-quality food provision, inadequate amount of food allocated for the academic year, lack of necessary infrastructure for the program, and lack of training in sanitation and hygiene for cooks were among the major challenges identified. Therefore, program challenges need high-level attention in order to make the school feeding program more successful in Sidama Region, Ethiopia.

Vitamin D binding protein gene polymorphisms are associated with lower plasma 25-hydroxy-cholecalciferol concentrations in Ethiopian lactating women.

Ethiopian women have been reported to have low plasma 25-hydroxy-cholecalciferol (25(OH)D) concentrations despite an abundance of sunshine. Low dietary vitamin D intake, limited skin exposure to sun, and genetics are among factors suggested to affect vitamin D status in this population. In this study (Clinical Trial NCT02210884), we hypothesized that polymorphisms in the vitamin D binding protein (VDBP) gene (rs7041, rs4588) are associated with reduced plasma 25(OH)D concentrations in Ethiopian women. Lactating Ethiopian women (n = 110) were randomly assigned to weekly administration of vitamin D3 (15,000 IU) or a placebo. Plasma 25(OH)D was measured at baseline (within 2 weeks of delivery, before supplementation) and at 3, 6, and 12 months after delivery. Associations between VDBP polymorphism status for rs7041 and rs4588 and plasma 25(OH)D were determined by analysis of variance and multiple linear and logistic regressions. Multiple linear regression with maternal age as a covariate revealed that rs7041 is associated with reduced plasma 25(OH)D (P = .021) and more risk alleles at rs7041 and rs4588 are associated with reduced plasma 25(OH)D (P = .017). Logistic regression models for vitamin D insufficiency showed that additional risk alleles for rs7041 and rs4588 are associated with increased odds ratios (OR = 1.66; 95% CI, 1.10-2.62; P = .019) for plasma 25(OH)D below 40 nmol/L. Supplementation increased plasma 25(OH)D at 3 months in women with fewer risk alleles and across all genotypes at 6 and 12 months. VDBP polymorphisms may contribute to vitamin D insufficiency in Ethiopian lactating women. Furthermore, VDBP polymorphisms may blunt short-term responses to vitamin D supplementation and require longer periods of intervention.

Effect of school feeding program on the anthropometric and haemoglobin status of school children in Sidama region, Southern Ethiopia: a prospective study.

Ethiopia recently scaled up the implementation of a school feeding program (SFP) as a targeted intervention for protecting disadvantaged school children from hunger and food insecurity. However, the contribution of the program to advancing the nutritional status of children has not been adequately explored. We assessed the effect of SFP on the anthropometric and haemoglobin status of school children in Sidama Region, Southern Ethiopia. Our prospective cohort study compared the height-for-age z-score (HAZ), BMI-for-age z-score (BAZ) and haemoglobin concentration of SFP beneficiary (n 240) and non-beneficiary (n 240) children, 10-14 years of age. The children were recruited from 8 SFP implementing and 8 control schools using a multistage sampling procedure and were followed for an academic year. The SFP intervention and control schools were matched one-to-one based on agro ecological features and geographical proximity. Exposure, outcome and pertinent extraneous variables were collected through baseline and end-line surveys. Multilevel difference-in-differences (DID) analysis was used to measure the net effect on the outcomes of interest. In the multivariable DID model adjusted for potential confounders including maternal and paternal literacy, household monthly income, wealth index and household food insecurity, the SFP did not show significant effects on the haemoglobin concentration (ß = 0⋅251, 95 % confidence interval (CI): -0⋅238, 0⋅739), BAZ (ß = 0⋅121, 95 % CI: -0⋅163, 0⋅405) and HAZ (ß = -0⋅291, 95 % CI: -0⋅640, 0⋅588) of children.

The associations between women's empowerment measures, child growth and dietary diversity: Findings from an analysis of demographic and health surveys of seven countries in Eastern Africa.

Evidence on the efficacy of women's empowerment to improve child growth and minimum dietary diversity (MDD) in the Eastern Africa (EA) region is limited. This cross-sectional study used recent Demographic and Health Survey data of mother-child dyads from seven countries in EA to examine the associations between women's empowerment measures, child growth and MDD. Length-for-age z-scores, weight-for-length z-scores and weight-for-age z-scores were used to categorize growth indicators of 6-23 months old children. Multivariable logistic regression was used to identify significant associations. Among all countries, 32%-59% of children experienced growth failure. Children meeting MDD were 18%-45%. Women having self-esteem were associated with lower odds of stunting (adjusted odds ratio [AOR] = 0.62 in Rwanda), wasting (AOR = 0.38 in Uganda), underweight (AORs = 0.60 and 0.57 in Tanzania and Uganda, respectively) and growth failure (AOR = 0.64 in Rwanda). Having health decision control in Burundi was associated with lower odds of stunting (AOR = 0.49) and child growth failure (AOR = 0.52) and higher odds of meeting MDD (AOR = 2.50). Having Legal empowerment among women increased the odds of stunting (AOR = 1.79 in Burundi), underweight (AOR = 1.77 in Uganda) and growth failure (AOR = 1.87 in Burundi). Economic empowerment showed mixed associations with child growth and MDD among some countries. Women's self-esteem and health decision control were associated with better child growth and MDD for some countries in EA. Nutrition-sensitive interventions aimed at improving child growth and MDD should consider local contexts when addressing women's empowerment.

Urinary Aflatoxin M1 Concentration and Its Determinants in School-Age Children in Southern Ethiopia.

Aflatoxins are mycotoxins that can contaminate grains, legumes, and oil seeds. These toxic compounds are an especially serious problem in tropical and sub-tropical climates. The objective of this study was to raise awareness of aflatoxin exposure among primary school children in Shebedino woreda, southern Ethiopia, by measuring urinary aflatoxin M1 (AFM1). The study employed a cross-sectional design and systematic random sampling of children from eight schools in the district. The mean ± SD age of the children was 9.0 ± 1.8 years. Most (84.6%) households were food insecure with 17.9% severely food insecure. Urinary AFM1 was detected in more than 93% of the children. The median [IQR] concentration of AFM1/Creat was 480 [203, 1085] pg/mg. Based on a multiple regression analysis: DDS, consumption of haricot bean or milk, source of drinking water, maternal education, and household food insecurity access scale scores were significantly associated with urinary AFM1/Creat. In conclusion, a high prevalence of urinary AFM1 was observed in this study. However, the relation between AFM1 and dietary intake was analyzed based on self-reported dietary data; hence, all of the staple foods as well as animal feeds in the study area should be assessed for aflatoxin contamination.

Tella intake among pregnant and lactating mothers: may it affect child growth?

Alcohol abuse among women is a public health importance that may impair prenatal and postnatal growth. Tella is among the most common homemade alcoholic beverages in rural Ethiopia, but little is known about the magnitude of tella intake during pregnancy and lactation or its effects on child growth. The present study investigated associations between maternal tella intake and the growth of their children. A cross-sectional mixed-methods study was conducted with mothers (n 228) and their 12-36-month-old children and with key informants (n 12). Tella intake during most recent pregnancy and lactation was estimated retrospectively by glasses per drinking event and frequency of events. Nearly 80 % of mothers had consumed some amount of tella during their most recent pregnancy and lactation. Furthermore, 72 % of children had tasted or drunk tella at some time during their life. Stunting was 42 % and was significantly associated with maternal tella consumption at least every other day during pregnancy (adjusted odds ratio (AOR) 4⋅97, 95 % confidence interval (CI) 2⋅20, 11⋅25), male sex (AOR 2⋅31, 95 % CI 1⋅27, 4⋅19), two or more under-5-year-old children in the household (AOR 3⋅52, 95 % CI 1⋅49, 8⋅33) and family size >5 (AOR 1⋅84, 95 % CI 1⋅01, 3⋅36). Underweight was 24⋅6 % and was associated with the child drinking tella with their mother (AOR 4⋅23, 95 % CI 1⋅99, 8⋅97), being male (AOR 3⋅73, 95 % CI 1⋅73, 7⋅94), having ≥3 diarrhoeal episodes in the last 3 months (AOR 11⋅83, 95 % CI 4⋅22, 33⋅14) and being in the older age group (AOR 2⋅98, 95 % CI 1⋅09, 8⋅13). The associations between tella intake and child growth suggest the need to mitigate the effects of tella on child anthropometry.

Camel milk consumption is associated with less childhood stunting and underweight than bovine milk in rural pastoral districts of Somali, Ethiopia: a cross-sectional study.

Undernutrition is a major global health problem. Various types of animal milk are used for feeding children at early ages; however, associations of camel milk (CaM) and bovine milk (BM) with the nutritional status of children have not been explored. A comparative community-based cross-sectional study was conducted among pre-schoolers in rural pastoral districts of Somali, Ethiopia. Children were selected from households with lactating camels or cows. Anthropometric measurements followed standard procedures for height-for-age, weight-for-age and weight-for-height scores. Independent sample t-tests identified significant differences in anthropometric indices based on the type of milk consumed. Multivariable logistic regression was used to examine associations between milk consumption and other predictors of growth failures. The prevalence of stunting was 24⋅1 % [95 % confidence interval (CI) 20⋅5, 28⋅3] of pre-schoolers, 34⋅8 % (95 % CI 29⋅9, 39⋅6) were wasted and 34⋅7 % (95 % CI 30⋅1, 39⋅9) were underweight. Higher proportions of BM-fed children were severely stunted, wasted and underweight compared with CaM consumers. Using logistic regression models, children who consumed BM [adjusted odds ratio (AOR): 2⋅10; 95 % CI 1⋅22, 3⋅61] and who were anaemic (AOR: 4⋅22; 95 % CI 2⋅23, 7⋅98) were more likely to be stunted than their counterparts, while girls were less likely to be stunted than boys (AOR: 0⋅57; 95 % CI 0⋅34, 0⋅94). Similarly, children who consumed BM (AOR: 1⋅97; 95 % CI 1⋅20, 3⋅24), who were anaemic (AOR: 2⋅27; 95 % CI 1⋅38, 3⋅72) and who drank unsafe water (AOR: 1⋅91; 95 % CI 1⋅19, 3⋅07) were more likely to be underweight than their counterparts. In conclusion, CaM consumption was associated with lower prevalence of stunting and underweight than BM. Promoting CaM in pastoralist areas may help to curb the high level of undernutrition.

A role for zinc transporter gene SLC39A12 in the nervous system and beyond.

The SLC39A12 gene encodes the zinc transporter protein ZIP12, which is expressed across many tissues and is highly abundant in the vertebrate nervous system. As a zinc transporter, ZIP12 functions to transport zinc across cellular membranes, including cellular zinc influx across the plasma membrane. Genome-wide association and exome sequencing studies have shown that brain susceptibility-weighted magnetic resonance imaging (MRI) intensity is associated with ZIP12 polymorphisms and rare mutations. ZIP12 is required for neural tube closure and embryonic development in Xenopus tropicalis. Frog embryos depleted of ZIP12 by antisense morpholinos develop an anterior neural tube defect and lack viability. ZIP12 is also necessary for neurite outgrowth and mitochondrial function in mouse neural cells. ZIP12 mRNA is increased in brain regions of schizophrenic patients. Outside of the nervous system, hypoxia induces ZIP12 expression in multiple mammalian species, including humans, which leads to endothelial and smooth muscle thickening in the lung and contributes towards pulmonary hypertension. Other studies have associated ZIP12 with other diseases such as cancer. Given that ZIP12 is highly expressed in the brain and that susceptibility-weighted MRI is associated with brain metal content, ZIP12 may affect neurological diseases and psychiatric illnesses such as Parkinson's disease, Alzheimer's disease, and schizophrenia. Furthermore, the induction of ZIP12 and resultant zinc uptake under pathophysiological conditions may be a critical component of disease pathology, such as in pulmonary hypertension. Drug compounds that bind metals like zinc may be able to treat diseases associated with impaired zinc homeostasis and altered ZIP12 function.

Fathers' involvement in child care activities: Qualitative findings from the highlands of Madagascar.

Few studies have investigated fathers' roles in child care in Madagascar. This study explored the perceptions, attitudes, and practices regarding fathers' involvement in child care using qualitative methods. Ten focus group discussions were conducted among parents of children aged 6-23 months; seven were among mothers, and three among fathers. In-depth semi-structured interviews (n = 8) were also conducted with key informants. Discussions and interviews were audio-recorded and the verbatim transcripts in Malagasy were translated into English. Data were analyzed using the thematic analysis approach. Provision of financial and material support as well as teaching and playing with the child were the main perceived roles of fathers. In practice, fathers spent their time alone with their children playing and holding them when the mother was unavailable. Busy schedules and separation due to work were major barriers to fathers' involvement. Traditional gender roles for child care in which the mother is seen as primarily responsible for the child were salient across the data. Consequently, men involved in child care activities and their wives were often criticized by the community. Nevertheless, there was self-reported interest from both mothers and fathers in involving men more in child care. Interventions aimed to increase fathers' involvement in child care may be more successful when they focus on shifting the community perceptions on the division of responsibilities between fathers and mothers.

The effect of school feeding programme on class absenteeism and academic performance of schoolchildren in Southern Ethiopia: a prospective cohort study.

OBJECTIVE: Ethiopia recently scaled up the implementation of a school feeding programme (SFP). Yet, evidence on the impact of such programmes on academic outcomes remains inconclusive. We evaluated the effect of the SFP on class absenteeism and academic performance of primary school students (grade 5-8) in Sidama zone, Southern Ethiopia. DESIGN: This prospective cohort study enrolled SFP-beneficiary (n 240) and non-beneficiary (n 240) children 10-14 years of age from sixteen public schools and followed them for an academic year. School absenteeism was measured as the number of days children were absent from school in the year. Academic performance was defined based on the average academic score of the students for ten subjects they attended in the year. Data were analysed using multivariable mixed effects negative binomial and linear regression models. SETTING: Food insecure districts in Sidama zone, Southern Ethiopia. PARTICIPANTS: SFP-beneficiary and non-beneficiary children 10-14 years of age. RESULTS: The mean (sd) number of days children were absent from school was 4·0 (sd 1·5) and 9·3 (sd 6·0), among SFP beneficiaries and non-beneficiaries, respectively. Students not covered by the SFP were two times more likely to miss classes (adjusted rate ratio = 2·30; 95 % CI 2·03, 2·61). Pertaining to academic performance, a significant but small 2·40 (95 % CI 0·69, 4·12) percentage point mean difference was observed in favour of SFP beneficiaries. Likewise, the risk of school dropout was six times higher among non-beneficiaries (adjusted rate ratio = 6·04; 95 % CI 1·61, 22·68). CONCLUSIONS: SFP promotes multiple academic outcomes among socio-economically disadvantaged children.

Exposure to aflatoxins and fumonisins and linear growth of children in rural Ethiopia: a longitudinal study.

OBJECTIVE: We hypothesise that exposure to aflatoxins and fumonisins, measured in serum, alters protein synthesis, reducing serum protein and insulin-like growth factor 1 (IGF-1), increasing inflammation and infection, leading to child's linear growth failure. DESIGN: Children 6-35 months, stratified by baseline stunting, were subsampled from an intervention trial on quality protein maize consumption and evaluated at two time-points. SETTING: Blood samples and anthropometric data were collected in the pre-harvest (August-September 2015) and post-harvest (February 2016) seasons in rural Ethiopia. PARTICIPANTS: 102 children (50 stunted and 52 non-stunted). RESULTS: Proportions of children exposed to aflatoxin G1, aflatoxin G2 and aflatoxin M1 were higher in the pre-harvest (8, 33 and 7, respectively) compared to post-harvest season (4, 28 and 4, respectively). The proportion of children exposed to any aflatoxin was higher in the pre-harvest than post-harvest season (51 % v. 41 %). Fumonisin exposure ranged from 0 % to 11 %. In joint statistical tests, aflatoxin exposure was associated with serum biomarkers of inflammation (C-reactive protein, α-1-glycoprotein) and protein status (transthyretin, lysine, tryptophan), IGF-1 and linear growth (all P < 0·01). However, exposure to specific aflatoxins was not significantly associated with any biomarkers or outcomes (all P > 0·05). CONCLUSIONS: Aflatoxin exposure among rural Ethiopian children was high, with large variation between seasons and individual aflatoxins. Fumonisin exposure was low. There was no clear association between aflatoxin exposure and protein status, inflammation or linear growth. A larger study may be needed to examine the potential biological interactions, and the assessment of aflatoxins in food is needed to determine sources of high exposure.

Maternal experience of intimate partner violence is associated with suboptimal breastfeeding practices in Malawi, Tanzania, and Zambia: insights from a DHS analysis.

BACKGROUND: Despite widespread suboptimal breastfeeding practices and maternal experiences of intimate partner violence (IPV), the association of IPV and breastfeeding practices remains unclear. This study investigated the associations between maternal experience of physical, sexual, emotional violence, and controlling behaviors with suboptimal breastfeeding practices in Malawi, Tanzania, and Zambia. METHODS: Data included mother-infant dyads from the most recent Demographic and Health Surveys for Malawi (n = 1878), Tanzania (n = 3184), and Zambia (n = 3879). Intimate partner violence (physical, sexual, and emotional) was measured using the Revised Conflict Tactics Scale. Breastfeeding practices were early initiation of breastfeeding (within 1 h of birth), exclusive breastfeeding (in previous 24 h), and continued breastfeeding. Associations between experience of physical, sexual, or emotional violence or controlling behaviors and breastfeeding practices, as well as associations between the frequency of IPV and breastfeeding practices were assessed. RESULTS: Many Malawian (77.6%) and Zambian (67.7%) and just over half (53.6%) of Tanzanian mothers, initiated breastfeeding within 1 h of birth. Exclusive breastfeeding was 70.6% in Zambia and 60.1% in Malawi, while 55.0% of Tanzanian mothers breastfed exclusively. Continued breastfeeding to at least 1 year was high in Malawi 92.2%, Tanzania 93.4%, and Zambia 95.0%. Most mothers reported experiences of IPV in Tanzania 79.1%, Zambia 78.9%, and Malawi 73.9%. Mothers who experienced sexual IPV were significantly more likely to delay breastfeeding (Malawi [AOR 1.55 (1.14, 2.10)]; Tanzania [AOR 1.30 (1.04, 1.62)]; and Zambia [AOR 1.28 (1.06, 1.54)]). Sexual IPV in Malawi and Zambia was associated with greater odds of not exclusively breastfeeding (Malawi [AOR 1.90 (1.05, 3.45)]; Zambia [AOR 1.75 (1.15, 2.67)]). Tanzanian mothers who experienced IPV often or sometimes were two times more likely not to breastfeed at one-year post-delivery [AOR 2.23 (1.09,4.57)]. CONCLUSIONS: In the three countries investigated maternal experience of IPV was associated with suboptimal breastfeeding practices. Policies and programs targeting improved breastfeeding practices should consider screening during antenatal and postnatal care for experience of violence and support initiatives to reduce IPV.

Excessive intake of iodine and low prevalence of goiter in school age children five years after implementation of national salt iodization in Shebedino woreda, southern Ethiopia.

BACKGROUND: Iodine is a trace element required for the synthesis of thyroid hormones. The multiple effects of iodine deficiency on human health are called iodine deficiency disorders (IDDs). IDDs have been common nutritional problems in Ethiopia. In 2012, Ethiopia launched a national salt iodization program to address IDDs. The objective of this study was to assess the effects of this program after 5 years by measuring urinary iodine concentration (UIC) and prevalence of goiter in school age children as well as household salt iodine concentration (SIC). METHODS: A school-based cross-sectional design was employed. After ethical approval, 408 children from eight randomly selected primary schools provided urine samples. UIC was analyzed by inductively coupled plasma mass spectrophotometry (ICP-MS). A 10 g salt sample was collected from each household of a sampled child. SIC was analyzed with a digital electronic iodine checker (WYD, UNICEF) and goiter was assessed by palpation. RESULTS: The mean (±SD) age of the children was 9 ± 2 years. The prevalence of goiter was 4.2% and no child had grade 2 goiter. The median (IQR) UIC was 518 (327, 704) µg/L and UIC ranged from 3.1 to 2530 µg/L. Of the salt samples, 15.6% were not adequately iodized (< 15 ppm), 39.3% were adequately iodized (≥15 to ≤40 ppm), and 45.1% were > 40 ppm. SIC ranged from 4.2 to 195 ppm. Of the mothers, 92% said iodized salt prevents goiter and 8% mentioned prevents mental retardation. CONCLUSIONS: In 2017 iodine deficiency was no longer a public health problem in the study area. However, the high variability in UIC and SIC and excessive iodine intake are of great concern. It is vital to ensure that salt is homogenously iodized at the production site before being distributed to consumers.

Aflatoxin contamination of human breast milk and complementary foods in southern Ethiopia.

Exposure to unsafe level of aflatoxin in early life may lead to growth faltering. However, the extent of contamination of breast milk and complementary foods is poorly examined. We determined aflatoxin M1 (AFM1 ) and B1 (AFB1 ) contamination of human breast milk and cereal-based cooked complementary foods, respectively, among households having children 6-23 months of age in Sidama zone, southern Ethiopia. Data were collected through two cross-sectional surveys implemented in the wet (n = 180) and dry (n = 180) seasons. Eligible households (n = 360) were recruited from three agroecological zones (lowland, midland and highland, each with sample size of 120) using a multistage sampling technique. AFB1 and AFM1 levels were determined using enzyme-linked immunosorbent assay. Mann-Whitney U and Kruskal-Wallis tests were performed to compare aflatoxin levels between seasons and across the agroecological zones. Among 360 breast milk samples tested, 64.4% had detectable AFM1 and 5.3% exceeded the 0.025 parts per billion (ppb) limit set by the European Union for infant milk. The median AFM1 in the lowlands was significantly higher than in the other agroecological settings (P < 0.001). By season, AFM1 was higher in breast milk samples collected in the dry season (P = 0.041). AFB1 was detected in 96.4% of the food samples tested, and 95.0% had concentration exceeding the permissible European Union limit of 0.1 ppb. The median AFB1 was significantly higher in the lowland (P = 0.002), but there was no difference between the seasons (P = 0.386). The study indicated that, in southern Ethiopia, foods intended for infants are heavily contaminated with AFB1 . Contamination of breast milk is also a significant health concern.
