Abstract
OBJECTIVE To conduct a comprehensive systematic review and meta-analysis of the available literature on the anthropometric nutritional status of South African infants and children, 0-18 years old and to report on trends of changes in nutritional status over the period 1997-2022. DESIGN Systematic review and meta-analysis. SETTING Review of the available literature on the anthropometric nutritional status of South African infants and children, 0-18 years old, over the period 1997-2022. PARTICIPANTS South African infants and children, 0-18 years old. RESULTS Only quantitative data from ninety-five publications that described the nutritional status in terms of anthropometry were included. Most recent studies applied the WHO 2006 and 2007 definitions for malnutrition among children 0-5 years old and 5-19 years old, respectively. Meta-analysis of all prevalence data shows the highest stunting prevalence of 25·1 % among infants and preschool children, compared to 11·3 % among primary school-age children and 9·6 % among adolescents. Furthermore, the overweight and obesity prevalence was similar among children younger than 6 years and adolescents (19 %), compared to 12·5 % among primary school-age children. In national surveys, adolescent overweight prevalence increased from 16·9 % in 2002 to 23·1 % in 2011. Meta-regression analysis shows a decrease in stunting among children 6-18 years old and an increase in combined overweight and obesity in the 10-19 years age group. CONCLUSION The double burden of malnutrition remains evident in South Africa with stunting and overweight/obesity the most prevalent forms of malnutrition among children.

Abstract
BACKGROUND Undernutrition in the critical first 1000 days of life is the most common form of childhood malnutrition, and a significant problem in low- and middle-income countries (LMICs). The effects of undernutrition in children aged under five years are wide-ranging and include increased susceptibility to and severity of infections; impaired physical and cognitive development, which diminishes school and work performance later in life; and death. Growth monitoring and promotion (GMP) is a complex intervention that comprises regular measurement and charting of growth combined with promotion activities. Policymakers, particularly in international aid agencies, have differing and changeable interpretations and perceptions of the purpose of GMP. The effectiveness of GMP as an approach to preventing malnutrition remains a subject of debate, particularly regarding the added value of growth monitoring compared with promotion alone. OBJECTIVES To evaluate the effectiveness of child growth monitoring and promotion for identifying and addressing faltering growth, improving infant and child feeding practices, and promoting contact with and use of health services in children under five years of age in low- and middle-income countries. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was 3 November 2022. SELECTION CRITERIA We included randomised controlled trials (RCTs), cohort studies, and controlled before-after studies that compared GMP with standard care or nutrition education alone in non-hospitalised children aged under five years. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods to conduct a narrative synthesis. Our primary outcomes were anthropometric indicators, infant and child feeding practices, and health service usage. Secondary outcomes were frequency and severity of childhood illnesses, and mortality. We used GRADE to assess the certainty of evidence for each primary outcome. MAIN RESULTS We included six studies reported in eight publications. We grouped the findings according to intervention. Community-based growth monitoring and promotion (without supplementary feeding) versus standard care We are unsure if GMP compared to standard care improves infant and child feeding practices, as measured at 24 months by the proportion of infants who have fluids other than breast milk introduced early (49.7% versus 70.5%; 1 study; 4296 observations; very low-certainty evidence). We are unsure if GMP improves health service usage, as measured at 24 months by the proportion of children who receive vitamin A (72.5% versus 62.9%; 1 study; 4296 observations; very low-certainty evidence) and the proportion of children who receive deworming (29.2% versus 14.6%; 1 study; 4296 observations; very low-certainty evidence). No studies reported selected anthropometric indicators (weight-for-age z-score or height-for-age z-score) at 12 or 24 months, infant and child feeding practices at 12 months, or health service usage at 12 months. Community-based growth monitoring and promotion (with supplementary feeding) versus standard care Two studies (with 569 participants) reported the mean weight-for-age z-score at 12 months, providing very low-certainty evidence: in one study, there was little or no difference between GMP and standard care (mean difference (MD) -0.07, 95% confidence interval (CI) -0.19 to 0.06); in the other study, mean weight-for-age z-score worsened in both groups, but we were unable to calculate a relative effect. GMP versus standard care may make little to no difference to the mean height-for-age z-score at 12 months (MD -0.15, 95% CI -0.34 to 0.04; 1 study, 337 participants; low-certainty evidence). Two studies (with 564 participants) reported a range of outcome measures related to infant and child feeding practices at 12 months, showing little or no difference between the groups (very low-certainty evidence). No studies reported health service usage at 12 or 24 months, feeding practices at 24 months, or selected anthropometric indicators at 24 months. AUTHORS' CONCLUSIONS There is limited uncertain evidence on the effectiveness of GMP for identifying and addressing faltering growth, improving infant and child feeding practices, and promoting contact with and use of health services in children aged under five years in LMICs. Future studies should explore the reasons for the apparent limited impact of GMP on key child health indicators. Reporting of GMP interventions and important outcomes must be transparent and consistent.

Abstract
OBJECTIVE Efficacy studies show early nutrition interventions improving infant nutrition status, but understanding caregiver acceptability is required for implementation of such interventions. This systematic review examines caregivers' perceptions of nutrition interventions in young children. DESIGN We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, CINAHL and PsychINFO from date of online journal inception through December 2020. Interventions included oral (powder/liquid/tablet) and/or intravenous supplementation, food fortification and nutrition counselling. Inclusion criteria included primary research, data presented on caregiver perception and studies published in English. Quality assessment was performed using the Critical Appraisal Skills Programme tool. Studies underwent narrative synthesis using inductive thematic analysis. SETTING No restriction. PARTICIPANTS Caregivers of children under 24 months of age. RESULTS Of 11 798 records identified, thirty-seven publications were included. Interventions included oral supplementation, food fortification and nutrition counselling. Caregivers included mothers (83 %), fathers, grandparents and aunts. Perceptions were gathered through individual interviews, focus group discussions, questionnaires, surveys and ratings. Totally, 89 % of studies noted high acceptability (n 33 most notably increased appetite (n 17). In total, 57 % of studies (n 21) cited low acceptability, commonly from side effects (n 13) such as gastrointestinal issues, appetite loss and stained teeth. CONCLUSIONS Positive perceptions and enthusiasm for interventions were frequently reported. Key to implementation was the increased appetite noted by caregivers. A substantial proportion of studies reported negative perceptions, mainly due to side effects. In future interventions, mitigation and education around common side effects are crucial for acceptability. Understanding both positive and negative caregiver perceptions is important for informing future nutrition interventions and strengthening sustainability and implementation.

Design Factors for Food Supplementation and Nutrition Education Interventions That Limit Conclusions about Effectiveness for Wasting Prevention: A Scoping Review of Peer-Reviewed Literature. Adv Nutr 2021; 13:328-341. [PMID: 34666351 PMCID: PMC8803494 DOI: 10.1093/advances/nmab107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Revised: 05/04/2021] [Accepted: 09/07/2021] [Indexed: 11/13/2022] Open
Abstract
We conducted a scoping review to characterize the evidence base for the effectiveness of food supplementation (FS), nutrition education (NE), or FS/NE interventions to prevent wasting among children aged 6 to 59 mo. We aimed to identify gaps in peer-reviewed literature and to develop recommendations for strengthening study designs. We identified 56 unique studies (FS = 21, NE = 19, FS/NE = 16) for which we assessed intervention design factors, implementation context, evaluation methods, and wasting impact. Compared with studies focused on stunting, fewer wasting-focused studies reported weight-for-height z score (WHZ). Midupper arm circumference (MUAC) was more commonly reported in wasting-focused studies (71.4%) than those focused on stunting (36.8%) or wasting and stunting (30.4%). FS studies measured anthropometry (mean, 95% CI) more frequently at every 11.3 (7.8, 14.8) wk than NE interventions at 36.3 (8.8, 62.1) wk (P = 0.036), but not FS/NE interventions at 25.8 (5.6, 49.1) wk (P = 0.138). NE interventions tended to be of longer duration than FS or FS/NE interventions. Only 6 studies followed and measured children after the intervention period ended. Across all studies, 45% reported a significant effect on wasting; these included FS, NE, and FS/NE interventions. The lack of comparability across studies limits conclusions about the effectiveness of specific types of interventions. To build a more unified evidence base for wasting prevention we recommend that future studies 1) report on a consistent set of metrics, including MUAC; 2) attempt to measure change in wasting incidence using more frequent measures; 3) measure wasting prevalence among the general population; 4) follow children postintervention to assess relapse; 5) measure food insecurity and diet quality; and 6) use harmonized protocols across multiple settings. Such efforts to improve study comparability will strengthen the evidence base, may help unite divergent professional communities, and ultimately accelerate progress toward eliminating child undernutrition.

Abstract
Childhood undernutrition coupled with poor feeding practices continues to be public health problems in many parts of the world and efforts to address them remain elusive. We tested the hypothesis that women who are exposed to radio health/nutrition education will demonstrate greater nutrition and health knowledge, positive attitudes towards preventive health and better dietary diversity practices for improved child growth. We used a two-arm, quasi-experimental, non-equivalent comparison group design with pre- and post-test observations to evaluate the intervention. The study population comprised 712 mothers with children aged 6-36 months who were randomly selected from five intervention districts and one comparison district in Northern Ghana. Difference-in-difference (DID) analysis was performed to assess study outcomes. After 12-month implementation of intervention activities, the minimum dietary diversity and the minimum acceptable diet improved significantly (DID 9⋅7 percentage points, P 0⋅014 and DID 12⋅1 percentage points, P 0⋅001, respectively) in the intervention study group, compared with the comparison group. Mothers in the intervention communities had a nutrition-related knowledge, attitudes and practices score that was significantly higher than their colleagues in the comparison communities (DID 0⋅646, P < 0⋅001). The intervention did not have significant effects on the nutritional status as measured by height-for-age Z-score or weight-for-height Z-score. The data provide evidence that health and nutrition education using radio drama significantly increased health-/nutrition-related knowledge but had little effect on nutritional status.

Abstract
BACKGROUND Nutrition interventions during the early years of a child's life are anchored on the need to provide good nutrition and proper health care to optimize their growth potential as adults. In the Philippines, undernutrition is a persistent problem among 0-10 year old Filipino children. In this age group, children consume a diet poor in quantity and quality. AIM This study aimed to assess the effects of a school-lunch and nutrition education intervention among schoolchildren in terms of attaining good nutrition. METHOD Using a quasi-experimental design, children aged 7-9 years from public elementary schools in the province of Laguna, Philippines were categorized into three intervention groups and one non-intervention group. Anthropometric measurements; nutrition knowledge, attitude and behavior; and food intake among children and households were collected at baseline and endline periods. SPSS for Windows version 16 and Stata version 15 were utilized for data analysis. RESULTS Mean scores on knowledge, attitude and behavior of schoolchildren in intervention groups increased significantly at endline (p<0.05). Protein requirement was met by more children and households than the energy requirement. Most children with normal nutritional status after the interventions (25.3%) belonged to the group with the complete intervention of school-lunch and nutrition education. CONCLUSIONS The provision of both school-lunch feeding and nutrition education is effective in improving the knowledge, attitude and behavior scores and nutritional status of schoolchildren. The adoption and institutionalization of complete intervention with school-lunch and nutrition education in elementary public schools should be pursued.

Abstract
Weak delivery systems reduce the potential of evidence-supp orted interventions to improve nutrition. We synthesized the evidence for the effectiveness of nutrition-specific intervention delivery platforms for improving nutrition outcomes in low and middle-income countries (LMIC). A systematic literature search for studies published from 1997 to June 2018 resulted in the inclusion of 83 randomized controlled trials (RCTs), quasi-randomized, and controlled before-after studies across a variety of delivery platforms. In this paper, we report on meta-analysed outcomes for community health worker (CHW) home visits and mother/peer group delivery platforms. Compared to care as usual, CHW home visits increased early initiation of breastfeeding (EIBF) (OR: 1.50; 95% CI: 1.12, 1.99; n = 10 RCTs) and exclusive breastfeeding (EBF) (OR: 4.42; 95% CI: 2.28, 8.56; n = 9 RCTs) and mother/peer groups were effective for improving children's minimum dietary diversity (OR: 2.34; 95% CI: 1.17, 4.70; n = 4) and minimum meal frequency (OR: 2.31; 95% CI: 1.61, 3.31; n = 3). Pooled estimates from studies using both home visit and group platforms showed positive results for EIBF (OR: 2.13; 95% CI: 1.12, 4.05; n = 9), EBF (OR: 2.43; 95% CI: 1.70, 3.46; n = 12), and < 5 wasting (OR: 0.77; 95% CI: 0.67, 0.89; n = 4). Our findings underscore the importance of interpersonal community platforms for improving infant and young child feeding practices and children's nutritional status in LMICs.

Abstract
BACKGROUND In the last 20 years, South Africa has experienced political, economic, and demographic transitions accompanied by an epidemiological transition. Like several sub-Saharan countries, the South African population is facing both under-and over-nutrition, and nutrition and lifestyle related chronic disease while the burden of infectious disease remains high. It is critical to understand these trends overtime in order to highlights the pitfalls and successful measures initiatives taken in the efforts to tackle malnutrition. The objective of this systematic review is to investigate the changes in the prevalence of stunting, a chronic form of undernutrition, in South Africa over 40 years, and to derive lessons from the South African experience, a country in an advanced process of transition in sub-Saharan Africa. METHODS We undertook a systematic review of publications selected from PubMed, Science Direct and Scopus. We included studies and surveys published between 1970 and 2013 if they reported the prevalence of stunting (low height-for-age) in children under-6 years of age living in South Africa. We excluded studies conducted in health facility outpatients or hospital wards, or children with known chronic and acute infectious diseases. We extracted Date of data collection, study setting, ethnicity, age, sex, sample size, growth references/standards, diagnostic criteria for stunting and prevalence of stunting from each study. RESULTS Over the last decade, the national prevalence of stunting has decreased. However, between and within provincial, age and ethnic group disparities remain. Unlike other countries in sub-Saharan Africa, no sex or rural/urban differences were found in preschool children. However, the analysis of long-term trends and identification of vulnerable groups is complicated by the use of different growth references/standards and sampling methods. CONCLUSION Despite economic growth, political and social transitions, and national nutritional programs, stunting remains stubbornly persistent and prevalent in South Africa. A multi-sectoral and public health approach is needed to: (i) better monitor stunting over time, (ii) combat malnutrition during the first thousand days of life through continued efforts to improve maternal nutrition during pregnancy and infant feeding practices.

Abstract
Background Low fruit and vegetable (FV) consumption is one of the top 10 global risk factors for mortality, and is related to increased risk for cancer, cardiovascular disease and diabetes. Many environmental, sociodemographic and personal factors affect FV consumption. The purpose of this review is to examine the effects of interventions delivered in the home, school and other nutritional environments designed to increase FV availability for five to 18-year olds. Methods The search included: 19 electronic bibliographic databases; grey literature databases; reference lists of key articles; targeted Internet searching of key organization websites; hand searching of key journals and conference proceedings; and consultation with experts for additional references. Articles were included if: in English, French and Spanish; from high-, middle-, and low-income countries; delivered to anyone who could bring about change in FV environment for 5 to 18 year olds; with randomized and non-randomized study designs that provided before-after comparisons, with or without a control group. Primary outcomes of interest were measures of FV availability. Results The search strategy retrieved nearly 23,000 citations and resulted in 23 unique studies. Interventions were primarily policy interventions at the regional or state level, a number of curriculum type interventions in schools and community groups and a garden intervention. The majority of studies were done in high-income countries. The diversity of interventions, populations, outcomes and outcome measurements precluded meta-analysis. The most promising strategies for improving the FV environment for children are through local school food service policies. Access to FV was successfully improved in four of the six studies that evaluated school-based policies, with the other two studies finding no effect. Broader state or federally mandated policies or educational programs for food service providers and decision makers had mixed or small impact. Similarly family interventions had no or small impact on home accessibility, with smaller impact on consumption. Conclusions The studies have high risk of bias but more rigorous studies are difficult to impossible to conduct in naturalistic settings and in policy implementation and evaluation. However, there are promising strategies to improve the FV environment, particularly through school food service policies.

Abstract
PURPOSE To develop nutrition education for preschool children based on Piaget's theory and to examine the effects of this education on children's nutritional knowledge, nutritional behaviors, and anthropometric measurements. DESIGN AND METHODS Pre- and postexperimental design. In experimental schools nutrition education was given. Children's nutritional knowledge, food consumption frequencies, and anthropometric measurements were evaluated. RESULTS The experimental group's nutritional knowledge scores increased and the group's food preferences positively changed. No significant difference was observed between the experimental and control groups' anthropometric measurements. PRACTICE IMPLICATIONS The nutrition education program used in this study may guide nurses in preparing education for preschoolers. The participation of families is recommended in their children's nutrition program.

Abstract
BACKGROUND Macronutrient and micronutrient deficiencies continue to have a detrimental impact in lower-income countries, with significant costs in morbidity, mortality, and productivity. Food is the primary source of the nutrients needed to sustain life, and it is the essential component that links nutrition, agriculture, and ecology in the econutrition framework. OBJECTIVE To present evidence and analysis of food-based approaches for improving nutritional and health outcomes in lower-income countries. METHODS Review of existing literature. RESULTS AND CONCLUSIONS The benefits of food-based approaches may include nutritional improvement, food security, cost-effectiveness, sustainability, and human productivity. Food-based approaches require additional inputs, including nutrition education, gender considerations, and agricultural planning. Although some forms of malnutrition can be addressed via supplements, food-based approaches are optimal to achieve sustainable solutions to multiple nutrient deficiencies.

Abstract
Exclusive breastfeeding during the first 6 months of infant's life is a public health recommendation and important factor for the promotion of optimal growth, health and behavioural development of each child. The accuracy of the mothers' self-reported past infant-feeding events was examined and compared with the isotopic dilution technique. Breastfeeding practices were assessed in a sample of 44 Cameroonian mother-infant pairs using dietary recall since birth. Intakes of breast milk and non-breast milk water were measured in the same sample using the dose-to-the-mother deuterium-oxide turnover technique and compared with questionnaire. Results showed that mothers' self-reported behaviour overestimates the exclusive breastfeeding rate. Seventy-five per cent of the mothers who claimed to be exclusively breastfeeding were found to be predominantly or partially breastfeeding by the dose-to-the-mother deuterium-oxide turnover technique. Only 11% of the infants were exclusively breastfed, and the breast milk output was not significantly affected (P ≤ 0.05) by the mother's body composition. Mean intakes of breast milk and non-breast milk water were 701 mL day(-1) and 268 mL day(-1), respectively. Introduction of non-breast milk foods is associated with a reduction in the level of breast milk intake, but the difference in breast milk intake was not significant between exclusively and predominantly breastfed infants. In conclusion, the dose-to-the-mother deuterium-oxide turnover technique can be applied to validate the mother's reports of infant-feeding practices, but non-breast milk water intake by breastfeeding category still needs to be normalized.

Abstract
AbstractObjectiveThe present paper presents a synthesis of available evidence to support action on the interventions that can effectively address the main drivers of child undernutrition in developing countries. It also discusses how interventions should be designed and identifies policy-relevant areas for further research.DesignA structured literature review of fifty-eight controlled evaluations and studies in developing countries were selected because they are methodologically sound, recent (reported within the past 10 years), report on nutritional status, cover a wide range of interventions and are implemented by a range of different agencies.SettingIndirect interventions in developing countries, which address the underlying and basic causes of child undernutrition and can potentially be implemented in the short to medium term.SubjectsChildren under 5 years of age and their mothers across a range of developing countries.ResultsEvidence has now accumulated to guide action on a range of indirect interventions that can reduce child undernutrition, but for all these interventions context is all-important. There is less evidence on how these interventions can be effectively implemented on a large scale.ConclusionsEfforts should be directed towards improving implementation of effective interventions on a large scale. Donors need to keep commitments both in dollar terms and in terms of the Paris Declaration so that the push for improved nutrition does not become donor driven. At the country level, there is a need for enabling governance structures, institutions and evidence-based decision making. Within countries there is a need for well-trained personnel with delegated authority, accountable to local people. It is essential for chains of accountability to be transparent and for active involvement of households in decision-making processes.

Abstract
Background As a result of inappropriate feeding, poor health and hygiene, and poor caring practices, the nutritional status of many young infants deteriorates with advancing age. Objective To explore the effectiveness of a nutrition education package to prevent malnutrition among young children. Methods A community-based, randomized, controlled trial was conducted among 605 normal and mildly malnourished children aged 6 to 9 months in 121 Community Nutrition Centers (CNCs) of the Bangladesh Integrated Nutrition Project (BINP) in four regions of Bangladesh from 2000 to 2002. The intervention group received weekly nutrition education based on the nutrition triangle concept of UNICEF for 6 months, whereas the control group received regular BINP services. Both groups were observed for a further 6 months to assess the sustainability of the effects. Information on socio-economic status, feeding patterns, morbidity, and anthropometric features was collected. Results A significant increase in the frequency of complementary feeding was observed in the intervention group as compared with the control group, and the increase was sustained throughout the observation period. The intervention group had a higher weight gain than the control group after the end of the intervention (0.86 vs. 0.77kg, p = 0.053) and after the end of the observation period (1.81 vs. 1.39 kg, p < .001). The proportion of normal and mildly malnourished children was greater in the intervention group than in the control group after the end of the observations (88.9% vs. 61.5%, p < .001). Nutrition education successfully prevented malnutrition in all the areas. Variation in the outcome of nutrition education among the regions was observed. Conclusions This culturally appropriate nutrition education package based on the nutrition triangle model effectively prevented growth faltering and malnutrition among young children.

Abstract
OBJECTIVE We evaluated the impact of the Community Nutrition Project (CNP) of Senegal, West Africa on the population. In poor urban districts, the CNP provided underweight 6- to 35-mo-old children with growth monitoring/promotion and food supplementation, and education for mothers for a period of 6 mo. METHODS A before/after intervention and intervention zone (IZ)/control zone (CZ) design was used to assess whether CNP had an impact 18 mo after it began in Diourbel. Exhaustive samples included children 6-35 mo old in the CZ (n = 895 before and 917 after) and IZ (n = 912 and 759). The impact was assessed by the differential effect of the zone on changes in underweight, wasting, and stunting defined by the threshold of -2 or -3 z scores. RESULTS The decrease in wasting was higher in the CZ (from 13.7% to 8.6% versus 11.3% to 10.8%, P = 0.042). Changes in stunting did not differ between zones (18.8% to 14.5% versus 15.1% to 14.7%, P = 0.21). However, in the IZ, severe wasting, stunting, and underweight disappeared in children 6-11 mo of age. In the CZ, the socioeconomic data and some outcomes in children reflected a favorable context independent of the CNP. CONCLUSION Despite a globally satisfactory decrease in malnutrition in the IZ, no impact was demonstrated because the same or an even larger decrease was observed in the CZ, highlighting the importance of relying on a quasi-experimental design. This may be explained in part by weaknesses in the process, which probably interfered with a potential impact, and by the high degree of population mobility, which could have interfered with efficiency assessed on a geographic scale.

Abstract
AbstractObjectiveTo study individual determinants of differential benefit from the Senegal Community Nutrition Project (CNP) by monitoring improvement in children's weight-for-age index (WA) or underweight status (WA < –2 Z-scores) during participation.DesignA follow-up study using the CNP child monitoring data. Linear general models compared variations in WA according to 14 factors describing the beneficiaries and CNP services.SettingPoor neighbourhoods of Diourbel, a large city in Senegal, West Africa. Over a 6-month period, the CNP provided underweight or nutritionally at-risk 6–35-month-old children with monthly growth monitoring and promotion and weekly food supplementation, provided that mothers attended weekly nutrition education sessions.SubjectsAll the children who participated in the first two years of the project (n = 4084).ResultsMean WA varied from − 2.13 (standard deviation (SD) 0.82) to − 1.58 (SD 0.81) Z-scores between recruitment and the end of the follow-up. The lower the child's initial WA, the greater was their increase in WA but the lower was the probability of recovery from underweight. Only 61% of underweight children recovered. Six months of CNP services may not be sufficient for catch-up growth of severely underweight children. The number of food supplement rations received was not a direct indicator of the probability of recovery. After adjustment for services received and initial WA, probability of recovery was lower in girls, in younger children, in twins and when mothers belonged to a specific ethnic group.ConclusionsDeterminants of benefit from CNP differed from the risk factors for underweight. Identification of participants with a lower probability of recovery can help improve outcome. Moreover, an explanation for the lack of recovery could be that many underweight children are stunted but not necessarily wasted.

Abstract
OBJECTIVE We evaluated feeding practices and growth patterns of infants in the central region of the Limpopo Province over the first 12 mo of life. METHODS A follow-up study on a cohort of term infants born to 276 mothers recruited during their third trimester of pregnancy was undertaken. The mothers were recruited by the nursing staff at nine randomly selected clinics. From this sample, 219 women gave birth at the local hospital and the infants were followed from birth to 12 mo. Data collected included infant feeding practices and anthropometry at regular intervals (1, 3, 6, 9 and 12 mo). The anthropometric measurements taken were body weight, length, and head circumference. RESULTS At birth 8.8% of infants had a low birth weight, 9.6% were stunted, 48.9% were underweight, and 7.3% were wasted. Mothers in this study breastfed their infants for long periods with more than 80% still breastfeeding by the ninth month. However, exclusive breastfeeding during the first 3 mo was uncommon as mothers tended to introduce supplementary feeds at an early age, with 56% of the infants receiving some form of supplement by the end of the first month. The most common supplementary foods were maize meal porridge and mabella (sorghum). Stunting became increasingly apparent in the early months with 30% of infants being stunted (<-2 standard deviations [SD] of the National Center for Health Statistics [NCHS] reference curves) by the first month, and this percentage remained high for the 12-mo period, remaining at below - 1 SD NCHS height-for-age standard. Increased weight gain was seen during the first 3 mo and then declined until mean weight-for-age at 12 mo was below 0 SD NCHS. Twelve percent of infants were overweight (>2 SD NCHS) by the 12th month. Postnatally the infants showed a pattern of gradual stunting. Postnatal factors associated with this pattern were related to maternal socioeconomic status, and these included the mother's level of education, employment status, parity, and access to electricity. CONCLUSION There was a high frequency of underweight infants at birth but stunting was less common. With respect to feeding practices, the mothers tended to introduce supplementary feeds at an early age.
