A study was undertaken to determine the energy and nutrient contribution of different food groups to the dietary intake of 6- to <9-month-old infants. An observational study was conducted using baseline data of a preliminary randomised controlled trial that aimed to determine the effect of egg consumption on infant growth. Participants resided in a peri-urban community (Jouberton) in North West province, South Africa. The study included 6- to <9-month-old infants (n = 155); 24-hour dietary recall data were available for n = 144. Most infants consumed either two (29.2%) or three (42.4%) out of eight food groups. The grains/roots/tubers group was consumed by 95.8% of infants; for consumers thereof, it contributed 75.5% of iron, 53.0% of thiamine and 42.5% of folate. Breast milk and dairy were consumed respectively by 64.4% of infants. For breastfed infants, breast milk was the major contributor of energy and fat, and some micronutrients (calcium, zinc, vitamin A, vitamin C, niacin and riboflavin); but they had lower intakes (p < 0.05) for all micronutrients except vitamin A compared with non-breastfed infants. For consumers (16.7%) of animal-source foods (ASFs), these contributed 42.8% for vitamin B12 and 33.4% for protein; and intake of protein, riboflavin and vitamin B12 was higher (p < 0.05) for consumers compared with non-consumers. The least consumed food groups were legumes (0.7%), flesh foods (6.9%) and eggs (10.4%). Grains/roots/tubers, dairy and breast milk made a major contribution to the intake of key nutrients. Animal-source foods were not consumed frequently, but for consumers thereof made a substantial contribution as well. Strategies to improve dietary diversity should encourage continued breastfeeding, aim to increase intake of food groups not frequently consumed and promote locally available food.

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.

Child mortality is a major public health problem in sub‐Saharan Africa and is influenced by nutritional status. A conceptual framework was proposed to explain factors related to undernutrition. Previously proposed conceptual frameworks for undernutrition do not consider child mortality and describe factors related to undernutrition from a qualitative viewpoint only. A structural equation modelling approach was applied to the data from World Bank and FAO databases collected from over 37 sub‐Saharan countries from 2000 to the most recent update. Ten food groups, exclusive breastfeeding, poverty and illiteracy rates, and environmental hygiene were investigated in relation to underweight, stunting, low birthweight, and child mortality. Standardized beta coefficient was reported, and graphical models were used to depict the relations among factors related to under‐five mortality in sub‐Saharan Africa. Child mortality in sub‐Saharan Africa ranged between 76 and 127 × 1,000. In the same period, low birthweight rate was about 14%. Poverty and illiteracy are confirmed to affect health resources, which in turn influenced nutritional status and child mortality. Among nutritional factors, exclusive breastfeeding had a greater influence than food availability. Low birthweight, more than underweight and stunting, influenced child mortality. Structural equation modelling is a suitable way to disentangle the complex quantitative framework among factors determining child mortality in sub‐Saharan Africa. Acting on poverty at the base appear to be the more effective strategy along with improvement of breastfeeding practice and improvement of hygiene conditions. [ABSTRACT FROM AUTHOR]
