Poor dietary diversity and low nutrient density of the complementary diet for 6- to 24-month-old children in urban and rural KwaZulu-Natal, South Africa

Low levels and determinants of appropriate complementary feeding practices among children aged 6-23 months from Tigray, Ethiopia: a community-based cross-sectional study

INTRODUCTION

Complementary feeding is considered appropriate when introduced timely at 6 months of age, and where it fulfils the minimum meal frequency, minimum dietary diversity and minimum acceptable diet. Sufficient evidence is available on the different individual indicators of appropriate complementary feeding.

OBJECTIVE

This study was conducted to assess the prevalence and determinants of appropriate complementary feeding practices among children aged 6-23 months in Tigray, Northern Ethiopia.

DESIGN AND SETTING

A community-based cross-sectional study was conducted in 52 districts of Tigray.

PARTICIPANTS

A total of 5321 children aged 6-23 months were included using stratified two-stage random sampling.

RESULTS

Approximately 19% of children received appropriate complementary feeding. Maternal residence in urban areas (adjusted OR (AOR) 1.26; 95% CI 1.062 to 1.489), maternal education (AOR 1.34; 95% CI 1.111 to 1.611), antenatal care (ANC) visits (AOR 1.75; 95% CI 1.343 to 2.281), household food security (AOR 2.81; 95% CI 2.367 to 3.330) and provision of colostrum to newborns (AOR 1.76; 95% CI 1.139 to 2.711) were found predictors of appropriate complementary feeding. Moreover, children in the 12-17 and 18-23 months age groups were 1.3 (AOR 1.30; 95% CI 1.083 to 1.551) and 1.7 (AOR 1.73; 95% CI 1.436 to 2.072) times more likely to receive appropriate complementary feeding respectively, compared with children aged 6-11 months.

CONCLUSIONS

Appropriate complementary feeding practices among children aged 6-23 months remain unacceptably low in Tigray. Recommendations to improve nutrition outcomes include counselling on age-appropriate complementary feeding, education for girls and women, targeting families through food security initiatives, provision of nutrition education on appropriate complementary feeding practices during ANC visits, supporting mothers to initiate breastfeeding within the first hour of delivery and crafting context-based messaging for rural families.

Minimum acceptable diet in a cohort of children aged between 6 and 15 months: Complementary feeding assessment and associated factors in the Brazilian western Amazon

OBJECTIVE

The goal of the article was to assess complementary feeding patterns, and associated factors, of children between 6 and 15-month old in Rio Branco-Acre, Brazil, based on the minimum acceptable diet indicator.

METHODS

This study was cross-sectional, including 857 children between ages 6 and 15 mo, from a 2015 birth cohort of Rio Branco, Brazil. The prevalence of complementary feeding indicators, minimum meal frequency, minimum dietary diversity, and minimum acceptable diet was estimated based on the recommendations of the World Health Organization. Sociodemographic characteristics, infant and maternal habits, prenatal information, birth characteristics, breastfeeding, and complementary feeding were evaluated. Differences between the proportions were evaluated by the χ2 test and univariate and multiple logistic regression analyses, to determine associated factors with child minimum acceptable diet.

RESULTS

The minimum frequencies of meals and dietary diversity were observed in 81.0% and 51.8% of the children, respectively. The minimum acceptable diet prevalence was 47.1%. Also, minimum acceptable diet was inversely associated with C, D, and E social classes (adjusted odds ratio = 0.49; 95% CI, 0.33-0.72), number of living siblings (adjusted odds ratio for two or three children = 0.69; 95% CI, 0.48-0.98, and adjusted odds ratio for ≥ 4 children = 0.56; 95% CI, 0.37-0.84). Maternal regular consumption of fruits, vegetables, and legumes (adjusted odds ratio = 2.62; 95% CI, 1.69-4.05), child age from 12 to 15 mo (adjusted odds ratio = 2.05; 95% CI, 1.32-3.18), and receiving guidance regarding complementary feeding during postnatal consultations (adjusted odds ratio = 1.38; 95% CI, 1.03-1.86) were directly associated with minimum acceptable diet.

CONCLUSIONS

Fewer than 50% of the children received adequate food with adequate frequency and diversity. Low socioeconomic status and having ≥ 2 living siblings reduced the chance of minimum acceptable diet, whereas maternal healthy diet, child age (12-15 mo), and complementary feeding counseling during postnatal appointments increased the chance of minimum acceptable diet.

Complementary Feeding in Western Cape, South Africa: Identifying Suboptimal Practices and Potential Targets for Intervention

Introduction Appropriate complementary feeding is important for the normal growth and development of children. This study aimed to describe the complementary feeding practices and identify suboptimal practices that would be possible targets for intervention to improve practices among mothers of infants aged six weeks to one year in Western Cape Province, South Africa. Methods This hospital-based cross-sectional study was conducted at the emergency unit of the Department of Paediatrics and Child Health of Tygerberg Academic Hospital, Cape Town, South Africa, between May 2017 and June 2017 among 110 mothers and their infants. Infants with minor ailments were included in the study. Patients requiring hospital admissions or severely ill infants requiring oxygen or ventilation, premature babies, and children with congenital anomalies were excluded from the study. The relationship between sociodemographic variables and the time of commencement of complementary food was described. Results The mean age of infants was 6.4±3.2 months, while the mean age of mothers was 27.6±5.5 years. On average, the age at introduction of complementary food to infants was 2.17±1.50 months. Among the complementary foods given to infants less than six months of age, cereals were the most commonly introduced (76.5%), while the least were sweet beverages (5.9%). Maternal age ≤ 34 years and first-born infant were significantly associated with early commencement of complementary food before six months of age (p=0.042 and p=0.032, respectively). Conclusion This study indicated that commencement of complementary food as early as two months of age with the use of non-nutritious and inappropriate food remains a significant problem in the region. There is a need for further education of mothers on appropriate complementary feeding practices given the importance of complementary feeding practices to the optimum growth and development of children.

Dietary diversity and nutritional status of children attending early childhood development centres in Vhembe District, Limpopo province, South Africa

The present study assessed dietary diversity and anthropometric status of children attending early development centres in South Africa. In the Vhembe District of Limpopo province, South Africa, 273 children were conveniently chosen from 8 randomly selected early childhood development centres for a cross-sectional study. Data were gathered via a questionnaire administered by the interviewer in June 2021. Height, body weight and mid-upper arm circumference were measured to assess anthropometric status. A 24-h dietary recall was obtained to provide information on dietary diversity. The prevalence of underweight, wasting and stunting was 9, 4 and 26 %, respectively. More than half of the children had a low dietary diversity score, according to the Food and Agriculture Organization scoring system for children. Grains, roots, tubers, dairy products, other fruits and vegetables, and flesh-based foods were the highest consumed food groups. The lowest consumption was for eggs, vitamin A-rich fruits and vegetables, legumes and nuts. Height for age and weight for age were significantly associated with dietary diversity score, but not weight for height. Children who did not meet the reference value of greater than 4 for dietary diversity had a significant risk of being underweight (AOR 0⋅25, 95 % CI 0⋅08, 0⋅75) and stunted (AOR 0⋅32, 95 % CI 0⋅14, 0⋅74). The nutritional status of the children was impacted by a lack of adequate dietary diversity. Young children in rural areas need to receive a wide range of food to promote greater diversification of diets in order to diminish the risk of undernutrition.

Nutrient density and oral processing properties of common commercial complementary porridge samples used in southern Africa: Effect on energy and protein intakes among children aged 6-24 months

Child malnutrition is an endemic public health problem in Africa. Infants are supposed to receive complementary foods from about 6 months onwards, as breastmilk alone no longer provide adequate nutrients. Commercially available complementary foods (CACFs) form an important part of baby foods in developing countries. However, systematic evidence on whether they really meet optimal quality specifications for infant feeding is limited. Some CACFs commonly used in Southern Africa and other parts of the world were investigated to establish if they meet optimal quality standards for protein and energy content, viscosity, and oral texture. For the energy content, most CACFs for 6-24-month-old children both in the dry and ready-to-eat forms (range: 372.0-1816.0 kJ/100 g), were below Codex Alimentarius guidelines. The protein density of all CACFs (0.48-1.3 g/100 kJ) conformed with Codex Alimentarius requirements, but some (33%) were below the minimum World Health Organization (World Health Organization. Regional Office for Europe (2019a). Commercial foods for infants and young children in the WHO European region) target of 0.7 g/100 kJ. Most CACFs had high viscosity values even at high shear rate of 50 s-1 , and were too thick or thick, sticky, grainy, and slimy, which may limit nutrient intake in infants, potentially causing child malnutrition. There is a need to improve the oral viscosity and sensory texture of CACFs for better nutrient intake by infants.

Comparison of Feeding Practices and Growth of Urbanized African Infants Aged 6-12 Months Old by Maternal HIV Status in Gauteng Province, South Africa

Appropriate feeding practices are protective against malnutrition and poor growth. We compared feeding practices and growth in HIV-exposed-uninfected (HEU) and HIV-unexposed-uninfected (HUU) between 6-12 months of age in urbanized African infants in South Africa. A repeated cross-sectional analysis was used to determine differences in infant feeding practices and anthropometric measures by HIV exposure status at 6, 9, and 12 months in the Siyakhula study. The study included 181 infants (86 HEU; 95 HUU). Breastfeeding rates were lower in HEU vs. HUU infants at 9 (35.6% vs. 57.3%; p = 0.013) and 12 months (24.7% vs. 48.0%; p = 0.005). Introduction to early complementary foods was common (HEU = 16.2 ± 11.0 vs. HUU = 12.8 ± 9.3 weeks; p = 0.118). Lower weight-for-age Z-scores (WAZ) and head circumference-for-age Z-scores (HCZ) were found in HEU infants at birth. At 6 months, WAZ, length-for-age Z-scores (LAZ), HCZ, and mid-upper-arm circumference-for-age Z-scores (MUACAZ) were lower in HEU vs. HUU infants. At 9 months, lower WAZ, LAZ, and MUACAZ were found in HEU vs. HUU infants. At 12 months, lower WAZ, MUACAZ, and weight-for-length Z-scores (-0.2 ± 1.2 vs. 0.2 ± 1.2; p = 0.020) were observed. HEU infants had lower rates of breastfeeding and poorer growth compared to HUU infants. Maternal HIV exposure affects the feeding practices and growth of infants.

Does the high dietary diversity score predict dietary micronutrients adequacy in children under 5 years old? A systematic review

BACKGROUNDS

Undiversified and monotonous diets can lead to deficiency disease, named micronutrient deficiency, more specifically among young children. Dietary diversity (DD) has been known as a valid indicator to assess micronutrient inadequacy of the diet. The aim of this study was to determine "is there an association between high dietary diversity and the micronutrient adequacy, in children under 5 years old?".

METHODS

PubMed, Scopus, ScienceDirect, Web of Sciences, and Google Scholar databases were searched until February 2022, without date restrictions, using relevant keywords. All original articles, written in English, evaluating the relationship between DD and micronutrient adequacy in children under 5 years were eligible for this review.

RESULTS

Totally, 1814 records were found in electronic search databases; after removing duplicated and irrelevant studies according to the title and abstract, the full text of the 35 articles was critically screened, in which 15 cross-sectional studies were included in this review. All of these studies reported that DD of infants and children under 5 years was positively associated with their micronutrient adequacy.

CONCLUSION

The findings indicate that in infants and children under 5 years, intake of various food groups reveals the adequate intake of micronutrients.

Optimal complementary feeding practices of children aged 6–23 months in three agro-ecological rural districts of Jimma zones of southwest Ethiopia

Despite the critical importance of complementary feeding, large proportions of children in developing countries are sub-optimally fed during 6–23 months of age. In Ethiopia, even though the government has been rolling out infant and young child feeding (IYCF) guidelines, the proportion of mothers adhering to the recommended optimal practices and its associated factors have not been assessed in different agro-ecological areas. Hence, the present study aimed to determine optimal complementary feeding practices and associated factors in three agro-ecological rural districts (high, mid and lowland) of southwest Ethiopia. A community-based cross-sectional study was carried out among 845 mothers-index young children 6–23 months Jimma zone. Multistage sampling was employed to select the study participants. Structured and pretested questionnaires were used to collect data and entered into Epi Data V.1.4.4.0. The data were analysed using SPSS version 20. Binary and multivariable logistic regressions were used to identify factors associated with optimal child-feeding practices. The significance of the association was determined at P < 0⋅05. The overall proportion of optimal complementary feeding practice (OCFP) was 9⋅4 % at 95 % CI (7⋅19, 11⋅08). The timely initiation of complementary feeding, minimum meal frequency, minimum dietary diversity and minimum acceptable diet was 52⋅2, 64⋅1, 17⋅2 and 12⋅2 %. Multivariable logistic regression showed that being in the highland districts, having good maternal knowledge, and mothers having primary school education, having a family size of less than six were positively associated with optimal complementary feeding practices. The findings showed that OCFP was low, especially in the midland agro-ecological districts.

Retail Cost and Energy Adjusted Cost Are Associated with Dietary Diversity and Nutrient Adequacy for Diets of 6–24 Months Children

Poor nutrition during the first two years of life has long term consequences, but resource-poor households often do not have the means to access nutrient-dense and diverse diets. Pooled data of 24-h dietary recalls (n = 3336) and 2019 retail food prices were analyzed to determine associations of retail cost and energy cost (per 100 kcal) with diet quality indicators for diets of 6–24-month-old South African children who were breastfed (BF-diet) and not breastfed (NBF-diet) during the 24-h recall period. Compared to the BF-diet, retail cost for the NBF-diet was three times higher for age 6–11 months, and double for age 12–17 months. Higher retail cost and energy cost were both associated with higher mean adequacy ratios and dietary diversity scores for BF and NBF diets, except energy cost for the NBF-diet for age 6–11 months. Overall, inclusion of flesh foods, vitamin A-rich fruits and vegetables, and other fruit and vegetables increased from the lowest to the highest retail cost tertile. The higher cost of more nutritious diets highlights the importance of the affordability of diets in interventions aimed at improving diet quality. Possible strategies include: identifying the most-affordable foods within each food group, focusing on foods that provide multiple key micronutrients, and the inclusion of locally available indigenous foods.

Mean ± Standard Deviation Intake Values for 1–<10-Year-Old South African Children for Application in the Assessment of the Inflammatory Potential of Their Diets Using the DII® Method: Developmental Research

This study aimed to develop a set of mean ± standard deviation (SD) intake values for South African (SA) children for 36 of the 45 food parameters included in the original Dietary Inflammatory Index (DII^®) tool. The SA food composition database contains 30 of the 45 food parameters included in the original DII^®, and a supplementary database was developed for six of the food parameters not included in the SA database. The SA child mean ± SD intake of macronutrients, micronutrients and select flavonoids was calculated by age in years, using eight data sets from dietary surveys conducted in SA in the last three decades. A total sample of 5412 children was included in the calculation of the mean ± SD. The current study sample was determined to be representative of 1–<10-year-old children in SA, and the plausibility of the mean intake values was confirmed by being in line with age-appropriate recommendations. Furthermore, an increase in energy, macronutrient, and most micronutrient intakes with increase in age was evident. The generated mean ± SD values for SA children can be used for calculation of the inflammatory potential of the dietary intake of SA children in the age range of 1–<10-year-old children.

Examining the Dietary Diversity of Children in Niger

Malnutrition is a major public health concern in Niger. The stunting rate in children in Niger is over 50%, one of the highest in the world. The purpose of this cross-sectional study was to examine children’s dietary diversity (CDD) and the maternal factors that impact CDD. A total of 1265 mother–child pairs were analyzed. Descriptive analysis was conducted to present maternal and child characteristics. To compare the mean scores of CDD in relation to the region, an independent sample t-test was conducted. A one-way ANOVA test was conducted to evaluate the CDD score by different age groups. A linear regression model was estimated to identify household, maternal and child factors that affect the CDD score. Our results indicate that most of the participants of our survey resided in rural areas and the majority (80.7%) of the mothers had no education. Factors such as region, children’s age, woman’s empowerment, vitamin A intake and wealth index were significant predictors of CDD (p < 0.05). The children residing in rural areas were more likely to have lower CDD scores (p < 0.05) than the children in urban areas, therefore becoming more susceptible to malnutrition.

Parental considerations during complementary feeding in higher income countries: a systematic review of qualitative evidence

OBJECTIVE

Worldwide data suggest a clash between parental complementary feeding practices and recommendations. Understanding the circumstances under which parents form their feeding practices is a crucial step to improve such practices. This paper aimed to systematically review the existing qualitative literature and synthesise the factors that parents take into consideration in relation to complementary feeding.

DESIGN

A systematic review was undertaken. Four electronic databases were searched for qualitative studies published after 2001 exploring parental experiences during complementary feeding. A framework that included authors' outcomes of interest was used to extract and synthesise study findings. The Standards for Reporting Qualitative Research were used to critically assess the included studies.

SETTING

Upper-middle- and high-income countries.

PARTICIPANTS

Parents with a child below the age of 3 years.

RESULTS

A total of forty-seven studies met the eligibility criteria and were included in this systematic review. The themes were organised into three main categories: (1) factors related to introduction of complementary foods; (2) factors related to the type of complementary foods and (3) factors related to both timing and type. The selected literature highlights: prevalent baby cues that prompt parents to introduce solid foods; parents' views on the recommended timing of complementary feeding; factors that drive the choice of complementary foods and perceived value in advice received from health professionals and grandmothers.

CONCLUSIONS

This systematic review indicates factors that can be barriers to complying with the complementary feeding guidelines, and therefore, its findings are pertinent to improving parental feeding practices through intervention studies and through infant feeding education in a primary care setting.

Impacts of an egg intervention on nutrient adequacy among young Malawian children

Eggs are a rich source of multiple nutrients that support child growth and development. Provision of eggs as a complementary food may improve dietary adequacy among young children at risk for undernutrition. Our objective was to test the impact of an egg intervention on the adequacy of total nutrient intakes and micronutrient density among 6- to 15-month-old Malawian children. Children 6 to 9 months old, living in Mangochi District, Malawi, were randomly assigned to the intervention group (n = 331) receiving an egg per day or a control group (n = 329) consuming their usual diet. Dietary intakes of macronutrients, vitamins and minerals were assessed using 24-h recalls at baseline, 3-month midline and 6-month endline, with repeat recalls in a subsample. Usual nutrient intake and micronutrient density distributions were modelled to estimate group means and prevalence of inadequacy. Group differences at midline and endline were tested using unequal variance t tests with bootstrapped standard errors. The egg intervention resulted in higher intakes of fat and protein and lower intakes of carbohydrates. The egg group had lower prevalence of inadequacy for selenium, vitamin A, riboflavin, vitamin B5 , vitamin B12 and choline. Micronutrient density inadequacy was lower in the egg group for vitamin A and choline at midline and endline, riboflavin at midline and vitamin B5 at endline. Inadequacy of nutrient intakes or density remained highly prevalent in both groups for multiple micronutrients. Though the egg intervention increased intakes of protein and several micronutrients, total intakes and micronutrient density of multiple micronutrients remained far below recommendations.

Parents' experiences of complementary feeding among a United Kingdom culturally diverse and deprived community

Complementary feeding practices and adherence to health recommendations are influenced by a range of different and often interrelating factors such as socio‐economic and cultural factors. However, the factors underlying these associations are often complex with less awareness of how complementary feeding approaches vary across the UK’s diverse population. This paper describes a qualitative investigation undertaken in a deprived and culturally diverse community in the UK which aimed to explore parents’ knowledge, beliefs and practices of complementary feeding. One hundred and ten mothers and fathers, self‐identified as being White British, Pakistani, Bangladeshi, Black African/Caribbean or Polish took part in twenty‐four focus group discussions, organised by age group, sex and ethnicity.

The findings revealed that most parents initiated complementary feeding before the World Health Organisation (WHO) recommendation of 6 months. Early initiation was strongly influenced by breast feeding practices alongside the extent to which parents believed that their usual milk; that is, breastmilk or formula was fulfilling their infants' nutritional needs. The composition of diet and parents' approach to complementary feeding was closely aligned to traditional cultural practices; however, some contradictions were noted. The findings also acknowledge the pertinent role of the father in influencing the dietary practices of the wider household. Learning about both the common and unique cultural feeding attitudes and practices held by parents may help us to tailor healthy complementary feeding advice in the context of increasing diversity in the United Kingdom.

Dietary Diversity and Nutritional Status of Preschool Children in North West Province, South Africa: A Cross Sectional Study

Preschool children consume diets inadequate to meet their macro and micronutrient requirements, which ultimately affect their nutritional status due to lack of dietary diversity. A cross sectional study was conducted to investigate the association between dietary diversity scores (DDS) and the nutritional status of 379 preschool children in North West Province of South Africa. A 24 h qualitative recall by mothers of their children's food consumption was used to calculate DDS based on 12-foods groups following Food and Agriculture Organization protocols. DDS was calculated by counting each of 12-food groups and classified as low (≤4), medium (5-8) and high (9-12). The weight and height of children were measured and height-for-age (HAZ), weight-for-age (WAZ) and BMI-for-age (BAZ) z-scores were calculated based on 2006 WHO standards. Stunting, underweight and thinness were defined as HAZ, WAZ and BAZ < -2SD, respectively. Linear and logistic regression analyses were used to assess the association between DDS and the nutritional indicators. Mean age for children was 4 ± 0.7 years, and the prevalence of stunting (29%), underweight (13%) and thinness (6%) was observed. Mean DDS was 4.39 ± 1.55 out of 12-food groups, with a prevalence of 61% and 39% for low and medium DDS, respectively. Cereals (100%) accounted for the main food group consumed, while fish and other seafood (17%) were the least consumed. Consumption of a diversified diet was associated with lower odds of being stunted [AOR = 0.25, 95%CI: 0.10 to 0.92] among the four-year olds, while in the unadjusted model, 5-year-olds had lower odds of being underweight [OR = -0.32, 95%CI: -0.57 to 0.07]. The findings of this study reinforce the importance of continued nutrition education of mothers, caregivers and preschool staff on the need to ensure consumption of diverse food sources in order to improve the nutritional status of children. Further studies are recommended on the association of DDS with the nutritional status, and factors associated with low dietary diversity among preschool children.

Multi-mycotoxin exposure of children (0-24 months) in rural maize-subsistence farming areas of the Eastern Cape Province, South Africa

In South Africa, child malnutrition is highly prevalent among children from in rural areas mostly at risk. In the Eastern Cape (EC) Province, maize is commonly used as complementary and weaning food. Previous studies conducted in parts of EC have indicated high levels of fumonisin B (FB) mycotoxins in home-grown maize, as well as the co-occurrence of other Fusarium mycotoxins, such as deoxynivalenol (DON) and zearalenone (ZEN). A cross-sectional study of children below 24 months was conducted in rural maize-subsistence farming areas in Centane, EC to determine mycotoxin exposure. Home-grown maize samples (n=171) were collected from households in the study area and analysed by LC-MS/MS for FB, DON and ZEN. Food intakes of 129 children were quantified using a validated quantitative food frequency questionnaire (QFFQ). Individual raw maize consumption was calculated using recipes from the QFFQ. Probable daily intakes (PDIs) for each mycotoxin were determined using a deterministic approach and were compared to the respective mycotoxins’ provisional maximum tolerable daily intake (PMTDI). The numerical means for total FB (sum of fumonisin B1, B2 and B3), DON and ZEN levels in home-grown maize were 1,035, 24.5 and 31.0 μg/kg, respectively. Mean daily maize intakes of children ranged from 2-321 g/day and increased with age. The mean PDIs for total FB, DON and ZEN were 8.4, 0.2 and 0.3 μg/kg body weight (bw)/day, respectively. Exposures stratified by age indicated persistent high mean PDIs for total FB, above the PMTDI of 2 μg/kg bw/day, ranging between 5.0-11.6 μg/kg bw/day. Mean exposure to DON and ZEN were below their relevant PMTDIs (1 and 0.5 μg/kg bw/day, respectively). Individually, 81 and 13% of children had exposures above the PMTDI for total FB and for ZEN, respectively. Results confirm the magnitude of FB exposure among vulnerable groups from rural maize subsistence farming areas in EC.

Regional Disparities in the Decline of Anemia and Remaining Challenges among Children in Tanzania: Analyses of the Tanzania Demographic and Health Survey 2004-2015

The burden of child anemia is on the decline globally but remains prevalent in low- and middle-income countries, including Tanzania. Evidence suggests regional variation and a slow pace of decline even in areas with high food production. The factors behind such decline and remaining challenges behind child anemia remain understudied in Tanzania. This secondary data analysis utilized data including 7361 and 7828 children from the Tanzania Demographic and Health Surveys (TDHS) conducted in 2004–2005 and 2015–2016 separately to examine the decline of child anemia and regional variation thereof. We used a geographic information system (GIS) to visualize the changes and differences between regions and the two study periods, and used regression analyses to examine the recent determinants of child anemia. Anemia has declined among children under five in Tanzania by 42% over a one-decade period, but remained high in relatively high food-producing regions. The risk of anemia is still higher among boys compared to girls (AOR = 1.39, p = 0.005), 41% higher among children lived in households with more than three under-five children compared to those households with only one child (p = 0.002); lower among children whose mothers were educated (p < 0.001) or had first given birth when aged over 25 (p = 0.033); and 34% less among children in the wealthiest households (p < 0.001). Efforts are needed to address social determinants of health, especially targeting women’s empowerment through decreasing the number of children and encouraging child spacing, and poverty reduction, particularly in high food producing regions.

Snack food and beverage consumption and young child nutrition in low- and middle-income countries: A systematic review

Although snacks can provide important nutrients for young children during the complementary feeding period, the increasing availability of snack foods and sugar‐sweetened beverages (SSB), often energy‐dense and nutrient‐poor, in low‐ and middle‐income countries (LMIC) is a concern. Such foods may displace consumption of nutritious foods in contexts where diets are often nutritionally inadequate and the burden of childhood malnutrition is high. This systematic review summarizes literature on the contribution of snack food/SSB consumption to total energy intakes (TEI) of children below 23 months of age in LMIC and associations between this consumption and nutritional outcomes. It also identifies areas where further research is needed. A systematic search of Embase, Global Health, and MEDLINE for literature published in January 1990–July 2018 was conducted. This search yielded 8,299 studies, 13 of which met inclusion criteria: Nine studies assessed % TEI from snack foods/SSB, and four studies assessed associations between snack food/SSB consumption and nutritional outcomes. Average % TEI from snack foods/SSB ranged from 13% to 38%. Findings regarding associations with growth were inconclusive, and no studies assessed associations with nutrient intakes. Variation in measurement of consumption and definitions of snack foods and SSB limited study comparisons. Further research is needed to understand how consumption of energy‐dense, nutrient‐poor snack foods and SSB influences undernutrition and overnutrition among young children during the complementary feeding period in settings that are experiencing dietary transitions and the double burden of malnutrition.

The Nutritional and Micronutrient Status of Urban Schoolchildren with Moderate Anemia is Better than in a Rural Area in Kenya

Low diet quality is a driver of general and micronutrient malnutrition in urban and rural areas. The objective was to compare malnutrition and micronutrient deficiencies linked to dietary intake among urban and rural schoolchildren from food insecure settings in Kenya. The cross-sectional study was conducted among urban and rural schoolchildren aged 7–9 years. Height and weight were measured, venous blood samples were assessed and data on dietary intake was collected. After screening out children with hemoglobin >12.2 g/dL and moderate or severe undernutrition, a total of 36 urban and 35 rural children participated. The prevalence of moderate underweight, wasting, and stunting were lower in urban than in rural children, with significant differences in median z-scores for underweight (p < 0.001) and wasting (p < 0.001). Significantly higher values for serum ferritin (p = 0.012) and zinc (p < 0.001) were found in urban children. Yet, the median adequacy ratios were higher for vitamin C (p = 0.045), iron (p = 0.003), and zinc (p = 0.003) in rural than in urban children. General nutritional, iron, and zinc status were significantly better in slightly anemic urban children than in rural ones. Improving the nutrition of schoolchildren in urban and rural settings requires different dietary approaches.

Dietary patterns of 6-24-month-old children are associated with nutrient content and quality of the diet

We determined the associations of dietary patterns with energy/nutrient intakes and diet quality. Previously collected single 24‐hr dietary recalls for children aged 6–11 months (n = 1,585), 12–17 months (n = 1,131), and 18–24 months (n = 620) from four independent studies in low socio‐economic populations in South Africa were pooled. A maximum‐likelihood factor model, with the principal‐factor method, was used to derive dietary (food) patterns. Associations between dietary pattern scores and nutrient intakes were determined using Kendall's Rank Correlations, with Bonferroni‐adjusted significance levels. For both 6–11 months and 12–17 months, the formula milk/reverse breast milk pattern was positively associated with energy and protein intake and mean adequacy ratio (MAR). The family foods pattern (6–11 months) and rice and legume pattern (12–17 months) were positively associated with plant protein, fibre, and PU fat; both for total intake and nutrient density of the complementary diet. These two patterns were also associated with the dietary diversity score (DDS; r = 0.2636 and r = 0.2024, respectively). The rice pattern (18–24 months) showed inverse associations for nutrient intakes and nutrient densities, probably because of its inverse association with fortified maize meal. The more westernized pattern (18–24 months) was positively associated with unfavourable nutrients, for example, saturated fat and cholesterol. These results highlight that underlying dietary patterns varied in terms of energy/nutrient composition, nutrient adequacy, nutrient densities of the complementary diet, and dietary diversity.

Magnitude and determinants of complementary feeding practices in Ethiopia: A systematic review and meta-analysis

BACKGROUND & AIM

Concurrent estimates on the magnitude and evidence on the determinants of complementary feeding (CF) practices in Ethiopia are currently disparate. Hence, this systematic review and meta-analysis assessed the magnitude and determinants of CF among children age 6-23 months in Ethiopia.

METHODS

Studies from various databases published until July 2018 were identified, selected, extracted and assessed for risk of bias by two authors independently. A random-effects model was used to pool the prevalence and odds ratios (ORs).

RESULTS

26 studies with 17, 383 children were included. The pooled prevalence estimate of timely initiated CF, minimum dietary diversity (DD), minimum meal frequency and minimum acceptable diet were 61.0%, 18.0%, 56.0%, and 10.0% respectively. The pooled prevalence of timely initiation and minimum DD were higher in Northern Ethiopia. On the other hand, except for the minimum meal frequency, all the three core indicators of CF were better in urban than rural settings. Child age, maternal and/or paternal education, paternal involvement, maternal DD, antenatal and postnatal care, and place of delivery were the main determinants that can increase appropriate CF practices.

CONCLUSION

The reported estimates of the prevalence of core CF indicators in Ethiopia remained poor. Therefore, the authors would like to acknowledge the effort that has been done by the minister of health and its partners including Alive & Thrive to improving CF practices in the country, however, these programs should be done more thoroughly, and scaled up by applying and adapting tested, proven approaches and tools in contexts.

Associations of plasma total phospholipid fatty acid patterns with feeding practices, growth, and psychomotor development in 6-month-old South African infants

The objective of this study was to assess plasma fatty acid (FA) patterns of 6-month-old South African infants and to determine their association with feeding practices, growth, and psychomotor development. Plasma total phospholipid FA composition (% of total FAs) of 6-month-old infants (n = 353) from a peri-urban township was analysed, and principal component and factor analysis were performed to identify plasma FA patterns. Feeding practices, anthropometric measurements, and psychomotor development scores were determined. Four major plasma phospholipid FA patterns were identified: A plant-based C18 FA, a high n-6 long-chain polyunsaturated fatty acids (LCPUFA), a C16:1 and long-chain saturated fatty acid (SFA), and a high n-3 and low n-6 LCPUFA pattern. Formula feeding was associated with higher, whereas breastfeeding was associated with lower scores for the plant-based C18 FA and C16:1 and long-chain SFA patterns. On the other hand, breastfeeding, the consumption of cow's milk, and the consumption of semisolid foods were associated with higher scores, whereas formula feeding was associated with lower scores for the high n-6 LCPUFA pattern. Breastfeeding and the consumption of semisolids were also associated with higher high n-3 and low n-6 LCPUFA pattern scores. The C16:1 and long-chain SFA and high n-3 and low n-6 LCPUFA patterns were positively associated with psychomotor development scores. In 6-month-old South African infants, we identified distinct plasma FA patterns that presumably represent the FA quality of their diet and that are associated with psychomotor development. Our results suggest that breast milk is an important source of n-6 LCPUFAs and formula-fed infants may be at risk of inadequate LCPUFA intake.

Dynamic Oral Texture Properties of Selected Indigenous Complementary Porridges Used in African Communities

Child malnutrition remains a major public health problem in low-income African communities, caused by factors including the low nutritional value of indigenous/local complementary porridges (CP) fed to infants and young children. Most African children subsist on locally available starchy foods, whose oral texture is not well-characterized in relation to their sensorimotor readiness. The sensory quality of CP affects oral processing (OP) abilities in infants and young children. Unsuitable oral texture limits nutrient intake, leading to protein-energy malnutrition. The perception of the oral texture of selected African CPs (n = 13, Maize, Sorghum, Cassava, Orange-fleshed sweet potato (OFSP), Cowpea, and Bambara) was investigated by a trained temporal-check-all-that-apply (TCATA) panel (n = 10), alongside selected commercial porridges (n = 19). A simulated OP method (Up-Down mouth movements- munching) and a control method (lateral mouth movements- normal adult-like chewing) were used. TCATA results showed that Maize, Cassava, and Sorghum porridges were initially too thick, sticky, slimy, and pasty, and also at the end not easy to swallow even at low solids content—especially by the Up-Down method. These attributes make CPs difficult to ingest for infants given their limited OP abilities, thus, leading to limited nutrient intake, and this can contribute to malnutrition. Methods to improve the texture properties of indigenous CPs are needed to optimize infant nutrient intake.

Contribution of commercial infant products and fortified staple foods to nutrient intake at ages 6, 12, and 18 months in a cohort of children from a low socio-economic community in South Africa

Fortification of two staple foods, maize meal and wheat flour (bread), is mandatory, and commercial infant products are widely available in South Africa. Using a 24-hr recall, we determined the contribution of these foods towards nutrient intakes at ages 6 (n = 715), 12 (n = 446), and 18 (n = 213) months in a cohort of children in a peri-urban community, North West province. On the day of recall, commercial infant products were consumed by 83% of children at 6 months, 46% at 12 months, and 15% at 18 months; fortified staples were consumed by 23%, 81%, and 96%, respectively. For consumers thereof, commercial infant products contributed 33% energy and 94% iron intakes at 6 months and 27% energy and 56% iron intakes at 12 months; nutrient densities of the complementary diet was higher than for nonconsumers for most micronutrients. For consumers of fortified staples, energy contribution thereof was 11% at 6 months versus 29% at 18 months; at 18 months, fortified staples contributed >30% of iron, zinc, vitamin A, thiamine, niacin, vitamin B6, and folate; at 12 months, nutrient densities of the complementary diet were higher for zinc, folate, and vitamin B6 but lower for calcium, iron, vitamin A, niacin, and vitamin C than nonconsumers. At ages 12 and 18 months, ~75% of children had low calcium intakes. At 12 months, 51.4% of consumers versus 25.0% (P = 0.005) of nonconsumers of fortified staples had adequate intakes (>EAR) for all eight fortificant nutrients. However, despite fortification, nutrient gaps remain.

Child Development and Nutritional Status in Ecuador

We assessed the development, nutritional status, and complementary feeding of 12- to 23-month-old children from Cuenca, Ecuador in 2013. Ecuador, an upper-middle-income country, developed a child policy in accordance with World Health Organization (WHO) guidelines. We collected cross-sectional survey data. Child development was assessed using the Integrated Management of Childhood Illness Guide–2011. The nutritional status was defined with WHO Child Growth Standards−2006. We investigated nutrient density, WHO Infant and Young Child Feeding Indicators, and nutrient supplementation intake of the complementary feeding. In all, 11.7% of children had “possible developmental delay,” stunting was identified in 29.4% of the children, and 25.3% faced overnutrition (overweight risk/overweight/obesity). The complementary feeding composition can be summarized as having adequate fat, high energy (MJ/day) and protein, and low iron and zinc. Children with “possible developmental delay” received less iron (P < .05) than children with normal development. Overall, 30.4% of children had minimum dietary diversity. A total of 47.7% of children received nutrient supplementation. This epidemiological profile of infants remains a challenge for Ecuador’s health programs.

Nutrient profile and energy cost of food sold by informal food vendors to learners in primary and secondary schools in the Eastern Cape, South Africa

OBJECTIVE

To assess type, nutrient profile and cost of food items sold by informal vendors to learners; and to determine nutrient content of corn-based processed snacks frequently sold.

DESIGN

Cross-sectional survey.

SETTING

Quintile 1 to 3 schools (n 36) randomly selected from six education districts; Eastern Cape, South Africa.ParticipantsInformal food vendors (n 92) selling inside or immediately outside the school premises.

RESULTS

Food items sold at most schools were corn-based processed snacks (94 % of schools), sweets (89 %), lollipops (72 %) and biscuits (62 %). Based on the South African Nutrient Profiling model, none of these foods were profiled as healthy. Foods less commonly sold were fruits (28 % of schools) and animal-source foods; these foods were profiled as healthy. Mean (sd) energy cost (per 418 kJ (100 kcal)) was highest for animal-source foods (R2·95 (1·16)) and lowest for bread and vetkoek (R0·76 (0·21)), snacks (R0·76 (0·30)) and confectionery products (R0·70 (0·28)). The nutrient profiling score was inversely related to the energy cost of the food item (r = -0·562, P = 0·010). Compared with brand-name corn-based processed snacks, non-branded snacks had lower energy (2177 v. 2061 kJ; P = 0·031) content per 100 g. None of the brand-name samples contained sucrose; six of the nine non-branded samples contained sucrose, ranging from 4·4 to 6·2 g/100 g.

CONCLUSIONS

Foods mostly sold were unhealthy options, with the healthier food items being more expensive sources of energy.

Infant Development at the Age of 6 Months in Relation to Feeding Practices, Iron Status, and Growth in a Peri-Urban Community of South Africa

Background: Evidence on the association between feeding practices, iron deficiency, anaemia, stunting, and impaired psychomotor development during infancy is limited. This study assessed the association between psychomotor development with early feeding practices, growth, iron status, and anaemia. Methods: This was cross-sectional baseline data of a randomised controlled trial which included 6-month-old infants and their mothers or primary caregivers (n = 750) in a peri-urban community in the North West province of South Africa. The Kilifi Developmental Inventory and a parent rating scale were used to assess psychomotor development. Feeding practices and anthropometric measurements were based on the World Health Organisation (WHO) guidelines. Anaemia and iron status were determined by blood sample analysis. Results: Prevalence of anaemia and stunting for the infants were 36.4% and 28.5%, respectively. Multiple regression analysis showed that birth weight was related to combined psychomotor scores (β = −3.427 (−4.603, 1.891), p < 0.001), as well as parent rating scores (β = −0.843 (−1.507, −0.180), p = 0.013). Length-for-age z-scores were associated with combined psychomotor scores (β = −1.419 (−2.466, 0.373), p = 0.008), as well as parent rating scores (β = −0.747 (−1.483, −0.010), p = 0.047). Conclusions: In this setting, with high prevalence of anaemia and stunting, important associations between lower psychomotor development scores and birthweight as well as length-for-age z-scores in 6-month-old infants were found. These findings warrant further investigation to develop a greater understanding of factors influencing the association between child growth and psychomotor development within the first 1000 days of life.

Iodine status and associations with feeding practices and psychomotor milestone development in six-month-old South African infants

Iodine is important for normal growth and psychomotor development. While infants below 6 months of age receive iodine from breast milk or fortified infant formula, the introduction of complementary foods poses a serious risk for deteriorating iodine status. This cross-sectional analysis assessed the iodine status of six-month-old South African infants and explored its associations with feeding practices and psychomotor milestone development. Iodine concentrations were measured in infant (n = 386) and maternal (n = 371) urine (urinary iodine concentration [UIC]), and in breast milk (n = 257 [breast milk iodine concentrations]). Feeding practices and psychomotor milestone development were assessed in all infants. The median (25th-75th percentile) UIC in infants was 345 (213-596) μg/L and was significantly lower in stunted (302 [195-504] μg/L) than non-stunted (366 [225-641] μg/L) infants. Only 6.7% of infants were deficient. Maternal UIC (128 [81-216] μg/L; rs  = 0.218, p < 0.001) and breast milk iodine concentrations (170 [110-270] μg/kg; rs  = 0.447, p < 0.0001) were associated with infant UIC. Most infants (72%) were breastfed and tended to have higher UIC than non-breastfed infants (p = 0.074). Almost all infants (95%) consumed semi-solid or solid foods, with commercial infant cereals (60%) and jarred infant foods (20%) being the most common solid foods first introduced. Infants who reported to consume commercial infant cereals ≥4 days weekly had significantly higher UIC (372 [225-637] μg/L) than those reported to consume commercial infant cereals seldom or never (308 [200-517] μg/L; p = 0.023). No associations between infant UIC and psychomotor developmental scores were observed. Our results suggest that iodine intake in the studied six-month-old infants was adequate. Iodine in breast milk and commercial infant cereals potentially contributed to this adequate intake.

The prevalence and factors associated with stunting among infants aged 6 months in a peri-urban South African community

OBJECTIVE

To determine the prevalence and factors associated with stunting in 6-month-old South African infants.

DESIGN

This cross-sectional study was part of the baseline of a randomized controlled trial. Weight-for-length, length-for-age and weight-for-age Z-scores were based on the WHO classification. Blood samples were analysed for Hb, plasma ferritin and soluble transferrin receptor (sTfR). Socio-economic, breast-feeding and complementary feeding practices were assessed by questionnaire. Setting/Subjects Infants aged 6 months (n 750) from a peri-urban area of Matlosana Municipality, North West Province of South Africa.

RESULTS

Stunting, underweight, wasting and overweight affected 28·5, 11·1, 1·7 and 10·1 % of infants, respectively. Exclusive breast-feeding to 6 months of age was reported in 5·9 % of the infants. Multivariable binary logistic regression showed that birth weight (OR=0·12; 95 % CI 0·07, 0·21, P8·3 mg/l) concentrations.

CONCLUSIONS

The association between stunting and lower birth weight, shorter maternal height and male sex reflects possibly the intergenerational origins of stunting. Therefore, interventions that focus on improving preconceptual and maternal nutritional status, combined with strategies to promote appropriate infant feeding practices, may be an important strategy to prevent stunting in vulnerable settings.

Poor dietary diversity and low nutrient density of the complementary diet for 6- to 24-month-old children in urban and rural KwaZulu-Natal, South Africa

Infants and toddlers have high nutritional requirements relative to body size but consume small amounts of food and therefore need nutrient-dense complementary foods. A cross-sectional study included children aged 6-24 months, stratified in three age categories (6-11 months, 12-17 months and 18-24 months) and randomly selected from an urban (n = 158) and a rural (n = 158) area, both of low socio-economic status, in the KwaZulu-Natal Province of South Africa. Dietary diversity and nutrient density of the complementary diet (excluding breast milk and formula milk) based on a repeated 24-h dietary recall was assessed. For breastfeeding children, nutrient density of the complementary diet was adequate for protein, vitamin A and vitamin C; and inadequate for 100% of children for zinc, for >80% of children for calcium, iron and niacin; and between 60% and 80% of children for vitamin B6 and riboflavin. Urban/rural differences in density for animal and plant protein, cholesterol and fibre occurred in 18-24-month-old children. Fewer than 25% of children consumed ≥4 food groups, with no urban/rural differences. Higher dietary diversity was associated with higher nutrient density for protein and several of the micronutrients including calcium, iron and zinc. The poor nutrient density for key micronutrients can probably be ascribed to lack of dietary variety, and little impact of mandatory fortification of maize meal/wheat flour on infants/toddlers' diet. Targeted strategies are needed to enable mothers to feed their children a more varied diet.
