Micronutrient supplementation practices in relation to the World Health Organisation 2013 guidelines on management of severe acute malnutrition.

In 2013, the World Health Organisation (WHO) updated the recommendations for micronutrient deficiency correction in hospitalised under-5 children with complicated severe acute malnutrition (SAM). This study aimed to describe the micronutrient deficiency correction practices in relation to WHO 2013 recommendations. Data from medical records of under-5 children admitted for SAM management at two hospitals in South Africa and three tertiary hospitals in Ghana were extracted. Micronutrient correction practices were compared to the WHO 2013 recommendations by considering the dosage, timing of micronutrient supplementation (vitamin A, iron and folic acid) and therapeutic feeds administered. In total, 723 medical records were included. Nearly half (48.3%) of the children received at least one of the studied micronutrients as a supplement. Vitamin A was supplemented in 27.4% of the children, while iron and folic acid were supplemented in 9.5% and 34.9%, respectively. Among the children who received vitamin A, 60.1% received the first dose on Day 1 of admission. Also, 46.4% of the iron-supplemented children received iron within the first week of admission. Vitamin A, iron and folic acid were administered within the dose range of 100,000-180,000 IU, 3.1-7.7 mg per kg per day, and 3-5 mg per day, respectively. Additionally, 71.7% of the children reportedly received therapeutic feeds that met WHO recommendations. The micronutrient deficiency correction practices regarding dose and timing differed from the 2013 WHO guidelines. Qualitative studies investigating the reasons for the disparities are recommended.

Determinants of undernutrition prevalence in children aged 0-59 months in sub-Saharan Africa between 2000 and 2015. A report from the World Bank database.

OBJECTIVE: To determine undernutrition prevalence in 0-59-month-old children and its determinants during the period 2000-2015 in sub-Saharan Africa. DESIGN: Ecological study of time series prevalence of undernutrition in sub-Saharan Africa assessed from 2000 to 2015. SETTING: Underweight and stunting prevalence from the World Bank database (2000-2015) were analysed. Mixed models were used to estimate prevalence of underweight and stunting. Country-specific undernutrition prevalence variation was estimated and region comparisons were performed. A meta-regression model considering health and socio-economic characteristics at country level was used to explore and estimate the contribution of different undernutrition determinants. PARTICIPANTS: Countries of sub-Saharan Africa. RESULTS: During 2000-2015, underweight prevalence in sub-Saharan Africa was heterogeneous, ranging between 7 and 40 %. On the other hand, stunting prevalence ranged between 20 and 60 %. In general, higher rates of underweight and stunting were estimated in Niger (40 %) and Burundi (58 %), respectively; while lowest rates of underweight and stunting were estimated in Swaziland (7 %) and Gabon (21 %). About 1 % undernutrition prevalence reduction per year was estimated across sub-Saharan Africa, which was not statistically significant for all countries. Health and socio-economic determinants were identified as main determinants of underweight and stunting prevalence variability in sub-Saharan Africa. CONCLUSIONS: Undernutrition represents a major public health threat in sub-Saharan Africa and its prevalence reduction during the period 2000-2015 was inconsistent. Improving water accessibility and number of medical doctors along with reducing HIV prevalence and poverty could significantly reduce undernutrition prevalence in sub-Saharan Africa.

Effect of fatty acid profiles in varying recipes of ready-to-use therapeutic foods on neurodevelopmental and clinical outcomes of children (6-59 months) with severe wasting: a systematic review.

CONTEXT: In 2020, 13.6 million children under 5 years suffered from severe acute malnutrition (SAM)/wasting. Standard ready-to-use therapeutic foods (RUTFs) improve polyunsaturated fatty acid (PUFA) status but contain suboptimal amounts of omega-3 (n-3) PUFAs with unbalanced n-6-to-n-3 PUFA ratios. OBJECTIVES: The aim was to compare the effects of RUTFs with different essential fatty acid contents on PUFA status, neurodevelopmental, and clinical outcomes (mortality, comorbidities, and recovery) of children with severe wasting. DATA SOURCES: Twelve databases, trial repositories, and article references with no publication limitations. DATA EXTRACTION: Ten studies from randomized, quasi, and cluster-randomized controlled trials providing RUTFs as home treatment to children 6-59 months with SAM/wasting were included. DATA ANALYSIS: Plasma phospholipid eicosapentaenoic acid content was higher in children receiving RUTF with altered essential fatty acid contents compared with standard RUTF (0.20 [0.15-0.25], P < 0.00001). Docosahexaenoic acid (DHA) status only improved in children receiving RUTF with added fish oil (0.33 [0.15-0.50], P = 0.0003). The Malawi Developmental Assessment tool (MDAT) global development and problem-solving assessment scores were higher in global assessment and gross motor domains in children receiving added fish oil compared with standard formulation (0.19 [0.0-0.38] and 0.29 [0.03-0.55], respectively). Children receiving high-oleic-acid RUTF (lowering the n-6:n-3 PUFA ratio of the RUTF) with or without fish oil had significantly higher scores in social domains compared with those receiving the standard formulation (0.16 [0.00-0.31] and 0.24 [0.09-0.40]). Significantly higher mortality risk was found in children receiving a standard formulation compared with RUTF with a lower n-6:n-3 PUFA ratio (0.79 [0.67-0.94], P = 0.008). CONCLUSION: Although lowering n-6:n-3 PUFA ratios did not increase plasma DHA, it improved specific neurodevelopmental scores and mortality due to lower linoleic acid (high-oleic-acid peanuts), higher alpha-linolenic acid (altered oil), or both. Additional preformed n-3 long-chain PUFAs (fish oil) with RUTF improved the children's DHA status, neurodevelopmental outcomes, and weight-for-height z score. More research is needed regarding cost, availability, stability, acceptability, and the appropriate amount of n-3 long-chain PUFAs required in RUTFs for the best clinical outcomes.

A Priori and a Posteriori Dietary Patterns among Pregnant Women in Johannesburg, South Africa: The NuPED Study.

Dietary pattern analyses allow assessment of the diet as a whole. Limited studies include both a priori and a posteriori dietary pattern analyses. This study aimed to explore the diet of pregnant women in urban South Africa through both a priori and a posteriori dietary pattern analyses and associated maternal and household factors. Dietary data were collected during early pregnancy using a quantified food frequency questionnaire from 250 pregnant women enrolled in the Nutrition During Pregnancy and Early Development (NuPED) cohort. A priori dietary patterns were determined using the Diet Quality Index-International (DQI-I), and a posteriori nutrient patterns using exploratory factor analysis. Based on the DQI-I, the study population followed a borderline low-quality diet. Three a posteriori nutrient patterns were identified: Pattern 1 "plant protein, iron, thiamine, and folic acid"; pattern 2 "animal protein, copper, vitamin A, and vitamin B12"; pattern 3 "fatty acids and sodium". Pattern 1 was associated with higher dietary quality (p < 0.001), lower maternal educational level (p = 0.03) and socioeconomic status (p < 0.001). Pattern 3 was significantly associated with lower dietary quality. The low dietary quality among pregnant women residing in urban South Africa should be addressed to ensure optimal maternal and offspring health outcomes.

Evaluation of the treatment guidelines, practices and outcomes of complicated severe acute malnutrition in children aged 0-59 months in sub-Saharan Africa: a study protocol for the SAMAC study.

INTRODUCTION: in hospitals across Africa, the case fatality rates of severe acute malnutrition (SAM) have remained consistently high (over 20%), despite the existence of the WHO treatment guideline. This has been attributed to inconsistencies in the implementation of the WHO treatment guidelines in sub-Saharan African countries. In spite of this awareness, the SAM treatment guidelines adopted by various sub-Saharan African countries and hospitals are unknown. Knowledge of the exact treatment practices employed in the management of SAM in different hospitals in sub-Saharan Africa is not known. This study aims to investigate the admission criteria, in-patient treatment guidelines and practices and outcomes of complicated SAM in sub-Saharan African children aged 0-59 months. METHODS: this is an observational study which involves the extraction of admission, treatment and discharge data from the medical records of infants and children aged 0-59 months diagnosed and treated for complicated SAM in sub-Saharan Africa. This information is being used to develop a comprehensive database on the treatment of complicated SAM across sub-Saharan Africa. Information on the national and hospital guidelines for the treatment of complicated SAM is also collected. RESULTS: results of this study will serve as a useful resource on the true reflection of the treatment of complicated SAM across sub-Saharan Africa and will provide valuable information for optimising SAM treatment. CONCLUSION: in order to advocate best practice and reduce SAM-related mortality in sub-Saharan Africa, the identification of the different diagnostic and treatment methods and respective outcomes across different hospitals and countries is imperative.
