RESUMO

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.

RESUMO

Brain zinc dysregulation is linked to many neurological disorders. However, the mechanisms regulating brain zinc homeostasis are poorly understood. We performed secondary analyses of brain MRI GWAS and exome sequencing data from adults in the UK Biobank. Coding ZIP12 polymorphisms in zinc transporter ZIP12 (SLC39A12) were associated with altered brain susceptibility weighted MRI (swMRI). Conditional and joint association analyses revealed independent GWAS signals in linkage disequilibrium with 2 missense ZIP12 polymorphisms, rs10764176 and rs72778328, with reduced zinc transport activity. ZIP12 rare coding variants predicted to be deleterious were associated with similar impacts on brain swMRI. In Neuro-2a cells, ZIP12 deficiency by short hairpin RNA (shRNA) depletion or CRISPR/Cas9 genome editing resulted in impaired mitochondrial function, increased superoxide presence, and detectable protein carbonylation. Inhibition of Complexes I and IV of the electron transport chain reduced neurite outgrowth in ZIP12 deficient cells. Transcriptional coactivator PGC-1α, mitochondrial superoxide dismutase (SOD2), and chemical antioxidants α-tocopherol, MitoTEMPO, and MitoQ restored neurite extension impaired by ZIP12 deficiency. Mutant forms of α-synuclein and tau linked to familial Parkinson's disease and frontotemporal dementia, respectively, reduced neurite outgrowth in cells deficient in ZIP12. Zinc and ZIP12 may confer resilience against neurological diseases or premature aging of the brain.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Child undernutrition is widespread in low- and middle-income countries (LMIC) and is associated with health and economic losses. Undernutrition is estimated to contribute to 3.1 million deaths per year in children less than 5 years of age. A complex causal and contextual factors contributing to child undernutrition have been assessed, but maternal depression, which could contribute to child undernutrition by interfering with the mother's child caring practice and ability, has been received little attention. The objective of this study was to assess the association between maternal postpartum depression symptoms and infant (5-10 months of age) stunting in northern Ethiopia. A community-based cross-sectional study was conducted among mother-infant pairs (n = 232) between March and April 2018. Through interviewer-administrated questionnaire, information on sociodemographic variables were collected, and maternal depression symptoms were assessed using the Edinburgh Postnatal Depression Scale (EPDS≥13). Infants' length and weight were measured and converted to length and weight for age Z scores using the WHO growth standards. Breastfeeding was a norm, but the adequacy of complementary feeding practice was sub-optimal. Only 25% of the infants met the minimum meal frequency (MMF), less than 10% met the minimum dietary diversity (MMD; 9%) or minimum acceptable diet (7%). Maternal depression was prevalent (22.8%) and was significantly associated with inappropriate complementary feeding and stunting (P < .05). Improving complementary feeding practices is central to preventing stunting in this and other settings. However, such efforts should integrate interventions that address maternal depression to improve child feeding and caring practices to effectively prevent stunting.

RESUMO

BACKGROUND: Optimal breastfeeding and complementary feeding practices are critical to prevent child undernutrition. Despite the occurrence of child undernutrition and widespread suboptimal feeding practices in Malawi, the association of breastfeeding and complementary feeding practices and undernutrition among Malawian children remains unclear. The purpose of the study was to determine the current breastfeeding and complementary feeding practices, to identify maternal determinants of each practice, and to analyze the associations between breastfeeding and complementary feeding practices with stunting, underweight, and wasting. METHODS: The most recent Malawi Demographic Health Survey (2015-2016) was used and data for 2294 children aged 0-23 months were included. A conceptual framework of five maternal domains: sociodemographic, health status, health behaviors, women's empowerment, and media exposure was used. Each domain contained exposure variables and the WHO Infant and Young Child Feeding indicators were used as outcome variables. All analyses were adjusted for clustering, and variables that reached a p-value of < 0.05 were considered significant in the final model. RESULTS: Among children, 30.8% were stunted, 9.9% were underweight, and 3.7% were wasted. Many (78%) were breastfed within the first hour of birth, 89% were breastfed until their first birthday, yet 40% were not exclusively breastfed to 6 months. Only 32% met minimum dietary diversity, 23% met minimum meal frequency, 12% met minimum acceptable diet and 12% consumed iron-rich foods. Children whose mothers lived in urban areas were less likely to be breastfed within 1 hour of birth but more likely to meet minimum dietary diversity. Children whose mothers listened to radio were more likely to meet minimum meal frequency. Children (13-23 months) who met minimum meal frequency and minimum acceptable diet were less likely to be underweight. CONCLUSIONS: Optimal breastfeeding and complementary feeding practices in Malawi remain suboptimal and child undernutrition remains problematic. Maternal characteristics from the five domains were significantly associated with optimal breastfeeding and complementary feeding indicators. Knowledge of these maternal determinants can assist in improving nutrition policies and interventions that aim to impact breastfeeding and complementary feeding practices and child growth in Malawi.

RESUMO

BACKGROUND: Maternal iodine deficiency (ID) during pregnancy has been recognized as a major cause of abortion, stillbirth, congenital abnormalities, perinatal mortality and irreversible mental retardation. In Ethiopia limited information is available regarding the epidemiology of maternal ID. The purpose of the present study was to assess the prevalence of iodine deficiency and associated factors among pregnant women in Ada district, Oromia region, Ethiopia. METHOD: A community based, cross-sectional study was conducted in rural areas of Ada district, October to November, 2014. Data were collected from 356 pregnant women selected by multistage cluster sampling technique. Presence of goiter was examined by palpation and urinary iodine concentration was measured using inductively-coupled-plasma mass spectrometry. Salt iodine concentration was determined using a digital electronic iodine checker. Statistical analysis was done primarily using binary logistic regression. The outputs of the analysis are presented using adjusted odds ratio (AOR) with the respective 95% confidence intervals (CI). RESULTS: The median urinary iodine concentration (UIC) was 85.7 (interquartile range (IQR): 45.7-136) µg/L. Based on UIC, 77.6% (95% CI: 73.0-82.0%) of the study subjects had insufficient iodine intake (UIC < 150 µg/L). The goiter rate was 20.2% (95% CI: 16.0-24.0%). The median iodine concentration of the household salt samples was 12.2 (IQR: 6.9-23.8) ppm. Of the households, only 39.3% (95% CI: 34.0-44.0%) consumed adequately iodized salt (≥15 ppm). Prevalence of goiter was significantly higher among pregnant women aged 30-44 years (AOR = 2.32 (95% CI: 1.05-5.14)) than among younger women and among illiterate women (AOR = 2.71 (95% CI: 1.54-4.79)). Compared to nulliparous, women with parity of 1, 2 and 3 or more had 2.28 (95% CI: 1.01-5.16), 2.81 (95% CI: 1.17-6.74) and 4.41 (95% CI: 1.58-12.26) times higher risk of goiter. CONCLUSION: Iodine deficiency was a public health problem in the study area. This indicates the need for further strengthening of the existing salt iodization program in order to avail homogenously and adequately iodized salt. Also it is necessary to find ways to provide iodine supplements as needed until universal salt iodization (USI) is fully established.

RESUMO

BACKGROUND: Studies evaluating child feeding in Madagascar are scarce despite its importance in child growth during the first two years of life. This study assessed the associations between the WHO infant and young child feeding (IYCF) indicators and stunting and identified determinants of inappropriate child feeding practices. METHODS: The most recent Demographic and Health Survey was used including a total of 1956 infants aged 0-23 months. Logistic regressions were performed for the association between IYCF indicators and stunting and for the determination of risk factors for inappropriate feeding practices. RESULTS: The rates of initiation of breastfeeding within one hour after birth (77.2%), continued breastfeeding at one year (99.6%) and timely introduction of solid, semi-solid or soft foods at 6-8 months (88.3%) were high. Exclusive breastfeeding under 6 months (48.8%), attaining minimum dietary diversity (22.2%) and consumption of iron-rich foods (19.6%) were relatively low. Higher length-for-age was associated with achieving minimum dietary diversity (p<0.01). The other indicators assessed (early initiation of breastfeeding, exclusive breastfeeding under 6 months, timely introduction of complementary foods and consumption of iron-rich foods) were not associated with stunting. Infants born to mothers who had first given birth at an age younger than 19 were more likely not to be breastfed within one hour after birth, not to be exclusively breastfed and not to have the recommended dietary diversity. Infants whose mothers had low media exposure were at increased risk of being inappropriately fed. Low household wealth also was associated with higher odds of not meeting the minimum dietary diversity. CONCLUSIONS: Despite almost total continued breastfeeding at one year and early initiation of breastfeeding by more than three-quarter of mothers, minimum dietary diversity scores were still low, confirming the need for more effective programs for improving child feeding practices in Madagascar. Improving dietary diversity in children aged 6-23 months may help reduce stunting. The identified risk factors for inappropriate feeding practices could be used in directing future nutrition sensitive interventions.

RESUMO

Madagascar is among countries where the prevalence of stunting is dramatically high in under 5 years old children. This study investigated the determinants of child stunting based on the UNICEF framework on the causes of malnutrition. A cutoff at 24 months was used to separate the child population into two groups. By using the latest Demographic and Health Survey (2009), logistic regressions were performed to determine the variables associated with stunting. In 2009, 40.1% of the 1,863 children aged 0-23 months and 53.9% of the 2,911 children aged 24-59 months were stunted contributing to the 48.5% overall stunting prevalence in the sample. Girls were less likely to be stunted (adjusted odds ratio with confidence interval [AOR] = 0.69 [0.55-0.88] and 0.84 [0.72-0.97], p < 0.01) than boys; the risk of stunting increased with age. Regarding underlying predictors, increased maternal height was associated with lower odds of stunting in both age groups (AOR = 0.75 [0.68-0.83] and 0.69 [0.61-0.77], p < 0.001). Children living in households using iodized salt (>15 ppm) had lower risk of stunting in the younger group (AOR = 0.76 [0.61-0.94], p < 0.05). Children living in urban areas were less likely to be stunted in both age groups (AOR = 0.67 [0.51-0.88] and 0.73 [0.59-0.90] respectively, p < 0.01]. Region of residence was also a significant basic factor for stunting. This study contributes to the understanding of the determinants of child stunting in Madagascar. The results confirmed the need for specific interventions for each of the two age groups.

RESUMO

BACKGROUND: Anthropometric characteristics and iron status affect cognitive performance in children. In addition, selenium can influence cognitive outcomes; protection of the brain from oxidative stress and its role in thyroid hormone metabolism are putative mechanisms. METHODS: To investigate their association with cognitive performance, anthropometric indicators, iron biomarkers, and serum selenium of children (n = 541) of 54-60mo of age from rural Ethiopia were assessed. Cognitive assessment was conducted with the administration of two reasoning subtests of the Wechsler Preschool and Primary Scale of Intelligence and the school readiness test. RESULTS: Stunting was found in 41.4 % of children, 28.7 % were underweight, and 6.3 % were wasted. The mean score of stunted children was lower than that of non-stunted children on non-verbal reasoning (7.0 ± 3.2vs7.9 ± 3.1; p = 0.01) and the school readiness tests (4.3 ± 2.2 vs 3.3 ± 2.1; p < 0.001). Compared to non-anemic children, anemic children had lower score for the verbal reasoning test (9.5 ± 1.7 vs 8.9 ± 2.2; p = 0.02). However, except for hemoglobin, none of the iron biomarkers had significant associations with the cognitive score of the study children (p > 0.05). Selenium deficient children had lower scores on all cognitive tests than normal children (p < 0.05). CONCLUSION: The present study finding linking chronic undernutrition and micronutrient deficiency to cognitive deficits suggests the need for designing effective intervention programmes to control for protein energy malnutrition and micronutrient deficiency and address cognitive development in children.

RESUMO

OBJECTIVE: Children from low-income countries consuming predominantly plant-based diets but little animal products are considered to be at risk of Fe deficiency. The present study determined the Fe status of children from resource-limited rural households. DESIGN: A cross-sectional study. SETTING: Twenty six kebeles (the smallest administrative unit) from six zones of the Amhara region, Ethiopia. SUBJECTS: Children aged 54-60 months (n 628). RESULTS: Grain, roots or tubers were the main dietary components consumed by 100 % of the study participants, followed by pulses, legumes or nuts (66·6 %). Consumption of fruit and vegetables (19·3 %) and meat, poultry and fish (2·2 %) was low. Children had a mean dietary diversity score of 2·1 (sd 0·8). Most children (74·8 %, n 470) were in the lowest dietary diversity group (1-2 food groups). Rate of any morbidity in the preceding 14 d was 22·9 % (n 114). Infection or inflammation (α1-acid glycoprotein >1·2 g/l) was present in 30·2 % (n 184) of children. Children had a high rate of stunting (43·2 %). Of the total sample, 13·6 % (n 82) of children were anaemic, 9·1 % (n 57) were Fe deficient and 5·3 % (n 32) had Fe-deficiency anaemia. Fe-deficiency erythropoiesis was present in 14·2 % (n 60) of children. CONCLUSIONS: Despite consuming a predominantly plant-based diet and little animal-source foods, there was a low prevalence of Fe-deficiency anaemia. This illustrates that dietary patterns can be inharmonious with Fe biochemical status; thus, Fe-related interventions require biochemical screening.

RESUMO

BACKGROUND: Inadequate nutrition during the first two years of life may lead to childhood morbidity and mortality, as well as inadequate brain development. Infants are at increased risk of malnutrition by six months, when breast milk alone is no longer sufficient to meet their nutritional requirements. However the factors associated with nutritional status of infants after 6 months of age have received little attention in pastoralist communities of Ethiopia. Therefore this study aimed to identify the factors associated with nutritional status of infants and young children (6-23 months) in Filtu town, Somali Region, Ethiopia. METHODS: A cross-sectional community-based study was conducted. Simple random sampling was employed to select 214 infants for the study. Univariable and multivariable logistic regressions models were used in the statistical analysis. The strength of association was measured by odds ratios with 95% confidence intervals. Both the crude (COR) and adjusted odds ratios (AOR) are reported. RESULTS: The prevalence of wasting, stunting and underweight among infants and young children were 17.5% (95% CI: 12.91-23.22), 22.9% (95% CI: 17.6-28.9) and 19.5% (95% CI: 14.58-25.3) respectively. The multivariable logistic regression model showed that breastfeeding was independently associated with reduced odds of wasting (AOR = 0.38(95% CI: 0.14-0.99)). Diarrhea in the past 15 days (AOR = 2.13 (95% CI: 1.55-4.69)) was also associated with increased odds for wasting. The independent predictors of reduced odds for stunting were dietary diversity score ≥ 4 (AOR = 0.45(95% CI: 0.21-0.95)) and introduction of complementary feeding at 6 months (AOR = 0.25 (95% CI: 0.09-0.66)). Bottle feeding was associated with increased odds of stunting (AOR = 3.83 (95% CI: 1.69-8.67)). Breastfeeding was associated with reduced odds of underweight (AOR = 0.24 (95% CI: 0.1-0.59)), while diarrheal disease in the past 15 days was associated with increased odds of underweight (AOR = 3.54 (95% CI: 1.17-7.72)). CONCLUSION: Under nutrition is a public health problem among infants and young children in Filtu town, Somali region Ethiopia. Breastfeeding was associated with lower odds of wasting and underweight while diarrheal disease was associated with higher odds of wasting and underweight. Low dietary diversity scores, inappropriate age of complementary feeding initiation and bottle feeding were identified to be significant predictors of stunting. Those factors should be considered for any intervention aimed to reduce under nutrition among infants and young children in Filitu town, Somali region, Ethiopia.

RESUMO

BACKGROUND: Regardless of efforts by the health sector and partner organizations, maternal and child malnutrition is still a challenge in Ethiopia. OBJECTIVE: To describe the context of current infant and child feeding patterns in Ethiopia. METHODS: Feeding patterns, diet content and quality, and nutritional outcomes and feeding practices of mothers of young children are described from literature review of a number of field studies. RESULTS: Protein and energy deficiencies and multiple micronutrient deficiencies are common. Breastfeeding is often prolonged until 2 years of age, with introduction of small amounts of poor-quality complementary foods. Vitamin A and iodine deficiencies have also been problems. Focus group discussions showed that mothers did not believe that animal-source foods are needed.by young children or schoolchildren. However, the Health Extension Program led by the Federal Ministry of Health promotes optimal child feeding as one of the health extension packages. CONCLUSIONS: Continued use of germination and fermentation of cereals should be encouraged to increase bioavailability of trace elements. Use of fat in the diet would increase energy density. To improve the situation, extension education, including nutrition and agricultural expertise delivered in aformat understandable to mothers about appropriate complementary feeding, including animal-source foods, is urgently needed, with expansion of governmental and nongovernmental resources.

RESUMO

BACKGROUND: Maternal undernutrition during pregnancy is currently estimated at 23.5% in Africa, which is worrying given the negative impacts of malnutrition on maternal and fetal birth outcomes. The current study aimed at characterizing the associations of maternal dietary intake and nutritional status with fetal growth at 14-26 weeks gestation. It was hypothesized that maternal dietary intake was positively associated with maternal nutritional status and fetal growth both in early and late pregnancy. METHODS: This was a cross-sectional survey of 870 pregnant women in mid-western Uganda conducted in August 2013. Data were collected on women's dietary intake (indicated by women's dietary diversity and the diet quality score) and nutritional status (indicated by hemoglobin level and mid-upper arm circumference) at 14-26 weeks gestation. Fetal growth was determined by symphysis-fundal height Z-scores processed using the INTERGROWTH-21st calculator. Associations between maternal dietary intake and nutritional status with fetal growth were determined using correlations and chi-square tests. RESULTS: Overall, only 25% had adequate dietary diversity and the most utilized food groups were White tubers, roots and starchy vegetables; Pulses, nuts and seeds; Cereals and grains, Dark green leafy vegetables, and Fats and oils. A larger proportion of younger women (15-29 y) were classified as anemic (20.4% versus 4.4%) and underweight (23.7% versus 5.0%) compared to older women (30-43 y). Additionally, women aged 15 to 24 years had significantly lower mean SFH-for-gestation age Z-scores than women 36-43 years (F4, 783 = 3.129; p = 0.014). Consumption of legumes nuts and seeds was associated with reduced risk of anemia while consumption of dairy products (mostly milk) was positively associated with better fetal growth. Surprisingly, low Hb level was positively associated with normal fetal growth (rP = -0.133; p = 0.016) after 20 weeks gestation, possibly indicating normal fetal growth paralleled with physiologically necessary hemodilution. CONCLUSIONS: Sub-optimal dietary patterns, characterized by limited dietary diversity and low protein intake, are likely to compromise maternal nutrition and fetal growth in limited resource settings. Improving pregnant women's access to cheaper but nutrient-dense protein sources such as pulses, nuts and dairy products (mostly milk) has potential to improve women's nutritional status and enhance fetal growth.

RESUMO

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.

RESUMO

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.

RESUMO

UNLABELLED: Background. Although the photosynthesis and bioavailability of vitamin D are influenced by various factors, vitamin D is produced in the skin by ultraviolet B (UVB) radiation from sunlight. However, vitamin D insufficiency is being recognized as a common problem, even in areas with abundant sunshine. OBJECTIVE: This study assessed vitamin D status by measuring plasma 25(OH)D concentrations in rural women in southern Ethiopia living in the Rift Valley at 7 degree3' N latitude. Methods. Nonpregnant women (n = 202) living in three adjacent rural communities volunteered to participate in this cross-sectional study. Demographic, socioeconomic, health, and food frequency data were acquired by questionnaire. Anthropometric measurements and a fasting venipuncture blood sample were obtained by qualified professionals. Body mass index (BMI) was calculated. ELISA kits from ImmunoDiagnostic Systems were used to determine concentrations of 25(OH)D with external quality control standards from UTAK Laboratories. RESULTS: The self-reported mean +/- SD age was 30.8 +/- 7.8 years. The mean number of pregnancies was 4.7 +/- 2.7, household size was 6.0 +/- 2.6, and BMI was 20.0 +/- 2.2. None of the participants reported ever consuming vitamin D-rich foods, fortified foods, or dietary supplements. Only 15.8% of the participants had 25(OH) D levels above 50 nmol/L, and 14.8% were below 30 nmol/L, which represents risk of deficiency relative to bone health. CONCLUSIONS: Vitamin D insufficiency is a serious problem in the study population, and living near the Equator does not assure adequate vitamin D status.

RESUMO

BACKGROUND: Maternal iodine nutrition during pregnancy is critical and deficiency during this period may compromise optimal fetal development. OBJECTIVE: To determine iodine status and knowledge of iodine deficiency disorders (IDD) of pregnant women in rural Sidama, southern Ethiopia. METHODS: A cross-sectional community-based study was conducted in three kebeles which were selected randomly from the eight kebeles in the study area using probability proportional to size methods. Data were collected in January, 2009, from 172 pregnant women. Main outcome measures were urinary iodine concentration (UIC), % of population with UIC < 20 microg/L, % of households using iodized salt, iodine content of salt and total goiter rate (TGR). RESULTS: Median UIC was only 15 microg/L compared to the 150 microg/L minimum recommendation from WHO/UNICEF/ ICCIDD for pregnant women. The UIC of 60% of the women was < 20 microg/L. More than 90% of households were not using iodized salt and median salt iodine content was almost zero compared to the recommended 15-40 mg/kg. TGR was 49% (95% CI: 42, 56) which is much higher than the 5% TGR cut-off signifying a problem of public health significance. In addition, > 90% of participants didn't know about IDD, about the cause of goiter or why iodized salt is important. CONCLUSION: Results indicated the presence of severe iodine deficiency in the study population; urgent intervention, through universal salt iodization, and iodine supplementation to high risk groups is required.
