Maternal Phenotype, Infant Size and Breast Milk Composition in Women Living With HIV
The impact of maternal factors on the size of HIV-exposed-uninfected (HEU) infants and breast milk composition is poorly understood. Anthropometry, bio-electrical impedance, haemoglobin and HIV viral load data of women living with HIV (WLWH) and without HIV (WLWOH) were compared and related to their infants' anthropometric Z-scores and breast milk macronutrients 6 weeks and 6 months postnatally. At both time points, WLWH (6-week: n = 83; 6-month:…
Infant Growth by Intergrowth‐21st and Fenton Growth Charts
Post-natal growth influences short- and long-term preterm infant outcomes. Different growth charts, such as the Fenton Growth Chart (FGC) and INTERGROWTH-21st Preterm Post-natal Growth Standards (IG-PPGS), describe different growth curves and targets. This study compares FGC- and IG-PPGS-derived weight-for-postmenstrual age z-score (WZ) up to 50 weeks postmenstrual age (PMA50) for predicting 1-year anthropometry in 321 South African preterm infan…
Exploring Infant Size and Body Composition at 18 Months
The first 1000 days of life lay the foundations for subsequent growth. This ambidirectional study, including prenatal, perinatal and postnatal factors, aimed to identify exposure variables affecting body size and composition and corresponding Z-score outcomes at age 18 months in infants born to women at low risk of adverse pregnancy outcomes in a peri-urban area of South Africa. Prenatal factors (maternal age, HIV status, anthropometry, parity, f…
Integrated growth assessment in the first 1000 d of life
Objectives: Prenatal growth affects short- and long-term morbidity, mortality and growth, yet communication between prenatal and postnatal healthcare teams is often minimal. This paper aims to develop an integrated, interdisciplinary framework for foetal/infant growth assessment, contributing to the continuity of care across the first 1000 d of life. Design: A multidisciplinary think-tank met regularly over many months to share and debate their p…
A novel screening tool to predict severe acute malnutrition through automated monitoring of weight‐for‐age growth curves
Weight-for-age (WFA) growth faltering often precedes severe acute malnutrition (SAM) in children, yet it is often missed during routine growth monitoring. Automated interpretation of WFA growth within electronic health records could expedite the identification of children at risk of SAM. This study aimed to develop an automated screening tool to predict SAM risk from WFA growth, and to determine its predictive ability compared with simple changes…
Physical Activity and Related Factors in Pre-Adolescent Southern African Children of Diverse Population Groups
Tailored obesity management includes understanding physical activity (PA) and its context, ideally in childhood before the onset of health risk. This cross-sectional study determined, by sex and population, the PA of Southern African pre-adolescent urban primary school children. PA was measured objectively (step count: pedometer) and subjectively (Physical Activity Questionnaire for Older Children [PAQ-C]), taking confounders (phenotype, school-b…
Considerations for the design of nutrition-sensitive production programmes in rural South Africa
Producing beyond that solely for home consumption has greater benefits for dietary diversity and a consumption-smoothing effect during the post-harvest period. Politicians and the scientific community should recognise the role that household and small-scale crop production plays in supporting household consumption and the provision of essential micronutrients despite constraints and disincentives. Production and education programmes should focus …
Technology in dietary assessment
Dietary assessment may be described as the science and art of evaluating the dietary intake of individuals or groups for research or as basis for nutrition care(1). While screening and comprehensive assessments have been differentiated(2), both are characterised by phases of varying detail. Data collection and data evaluation are respectively the beginning (input) and endpoint (output). The aim of a particular dietary evaluation will determine th…
Dietary Diversity and Vegetable and Fruit Consumption of Households in a Resource-Poor Peri-Urban South Africa Community Differ by Food Security Status
Sociodemographic, living standard measure, consumption of vegetables and fruit, and dietary diversity in relation to household food security were assessed. Using a hunger score, households were categorized as food secure (n = 125) or food insecure (n = 273). Food secure respondents had a higher mean dietary diversity score (3.98; 95%CI [3.79, 4.18] versus 3.65; 95% [CI 3.53, 3.77]), were more likely to eat vitamin A-rich foods (OR 1.15; 95% CI [1…
Screening for dietary fat intake of grade six children
As part of justifiable nutrition promotion, this study aimed to determine internal consistency of a dietary fat screener and to compare self-assessment to maternal assessment of fat intake of grade six (about 12 years old) learners in a South African public primary school. The children completed in school a pictorial, quantitative food frequency-type screener consisting of 10 high-fat food categories; mothers individually completed a text version…
