Abstract
CONTEXT The timing of introducing complementary feeding (CF) is crucial because premature or delayed CF can be associated with adverse health outcomes in childhood and adulthood. OBJECTIVE This systematic review aims to evaluate the impact of the timing of CF introduction on health, nutrition, and developmental outcomes among normal-term infants. DATA SOURCES Electronic databases and trial registries were searched, along with the reference lists of the included studies and relevant systematic reviews. DATA EXTRACTION Two investigators independently extracted data from the included studies on a standardized data-extraction form. DATA ANALYSIS Data were meta-analyzed separately for randomized controlled trials (RCTs) and observational studies on the basis of early introduction of CF (< 3 months, < 4 months, < 6 months of age) or late introduction of CF (> 6 months, > 8 months of age). Evidence was summarized according to GRADE criteria. In total, 268 documents were included in the review, of which 7 were RCTs (from 24 articles) and 217 were observational studies (from 244 articles). Evidence from RCTs did not suggest an impact of early introduction, while low-certainty evidence from observational studies suggested that early introduction of CF (< 6 months) might increase body mass index (BMI) z score and overweight/obesity. Early introduction at < 3 months might increase BMI and odds of lower respiratory tract infection (LRTI), and early introduction at < 4 months might increase height, LRTI, and systolic and diastolic blood pressure (BP). For late introduction of CF, there was a lack of evidence from RCTs, but low-certainty evidence from observational studies suggests that late introduction of CF (> 6 months) might decrease height, BMI, and systolic and diastolic BP and might increase odds of intestinal helminth infection, while late introduction of CF (> 8 months) might increase height-for-age z score. CONCLUSION Insufficient evidence does suggest increased adiposity with early introduction of CF. Hence, the current recommendation of introduction of CF should stand, though more robust studies, especially from low- and middle-income settings, are needed.

Abstract
A nationally generalisable cohort (n 5770) was used to determine the prevalence of non-timely (early/late) introduction of complementary food and core food groups and associations with maternal sociodemographic and health behaviours in New Zealand (NZ). Variables describing maternal characteristics and infant food introduction were sourced, respectively, from interviews completed antenatally and during late infancy. The NZ Infant Feeding Guidelines were used to define early (≤ 4 months) and late (≥ 7 months) introduction. Associations were examined using multivariable multinomial regression, presented as adjusted relative risk ratios and 95 % confidence intervals (RRR; 95% CI). Complementary food introduction was early for 40·2 % and late for 3·2 %. The prevalence of early food group introduction were fruit/vegetables (23·8 %), breads/cereals (36·3 %), iron-rich foods (34·1 %) and of late were meat/meat alternatives (45·9 %), dairy products (46·2 %) and fruits/vegetables (9·9 %). Compared with infants with timely food introduction, risk of early food introduction was increased for infants: breastfed < 6months (2·52; 2·19-2·90), whose mothers were < 30 years old (1·69; 1·46-1·94), had a diploma/trade certificate v. tertiary education (1·39; 1·1-1·70), of Māori v. European ethnicity (1·40; 1·12-1·75) or smoked during pregnancy (1·88; 1·44-2·46). Risk of late food introduction decreased for infants breastfed < 6 months (0·47; 0.27-0·80) and increased for infants whose mothers had secondary v. tertiary education (2·04; 1·16-3·60) were of Asian v. European ethnicity (2·22; 1·35, 3·63) or did not attend childbirth preparation classes (2·23; 1·24-4·01). Non-timely food introduction, specifically early food introduction, is prevalent in NZ. Interventions to improve food introduction timeliness should be ethnic-specific and support longer breast-feeding.

Total Liver Vitamin A Reserves, Determined With 13C2-Retinol Isotope Dilution, are Similar Among Tanzanian Preschool Children in Areas With Low and High Vitamin A Exposure. J Nutr 2023; 152:2699-2707. [PMID: 36178059 DOI: 10.1093/jn/nxac227] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 09/13/2022] [Accepted: 09/28/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND In Tanzania, some districts have single vitamin A (VA) interventions and others have multiple interventions. There is limited information on total liver VA reserves (TLRs) among preschool children (PSC) in Tanzania. OBJECTIVES We assessed total body VA stores (TBSs) and TLRs among PSC living in 2 districts with low and high exposures to VA interventions using 13C-retinol isotope dilution. METHODS A cross-sectional, health facility-based study was conducted in 2 districts with access to VA supplementation only (low exposure to VA interventions) or multiple interventions (high exposure to VA interventions) to determine TLRs in 120 PSC aged 36-59 months. A questionnaire was used to collect data. Height and weight were measured, and the prevalence of undernutrition was based on z-scores. Blood samples were collected for measurement of TBSs, TLRs, retinol, biomarkers of infection and inflammation, and hemoglobin. 13C2-retinyl acetate (1.0 μmol) was administered to each child after blood collection, and the second sample was taken 14 days later. Serum was analyzed with HPLC and gas chromatography-combustion-isotope ratio mass spectrometry. Mann-Whitney U test was used to compare medians of nonnormally distributed variables. Pearson χ2 test was used to assess associations between 2 categorical variables. RESULTS Median TBSs differed between PSC from low-exposure (196 μmol; IQR, 120 μmol) and high-exposure (231 μmol; IQR, 162 μmol) intervention areas (P = 0.015). Median TLRs were 0.23 μmol/g liver (IQR, 0.14 μmol/g liver) and 0.26 μmol/g liver (IQR, 0.16 μmol/g liver) from low- and high-exposure areas, respectively, which did not significantly differ (P = 0.12). Prevalences of VA deficiency (VAD; ≤0.1 μmol/g liver) were 6.3% and 1.7% for PSC from low- and high-exposure areas, respectively. There was no significant difference in VAD (P = 0.25). No child had hypervitaminosis A (≥1.0 μmol/g liver). CONCLUSIONS TLRs in Tanzanian PSC from 2 districts did not differ between low and high exposures to VA interventions. The majority had adequate VA stores. VAD in the study area presented a mild public health problem.

Abstract
BACKGROUND Childhood anemia is a global public health issue. In this study, we assessed the potential sociodemographic and dietary factors associated with the prevalence of anemia among children aged 6-59 months in Nigeria. METHODS In this cross-sectional study, we collected dietary information and demographic data on 6,338 children with anemia from the Nigerian Demographic and Health Surveys (2018). The association between the occurrence of anemia and the demographic and dietary factors was determined by conducting Chi-squared tests. Additionally, bivariate and multivariate order logit models were constructed and reported as odds ratios. RESULTS The results of the multivariate analysis showed that the risk of anemia was reduced by 13% and 44% in children aged 13-36 months (OR = 0.87; 95% CI = 0.77-0.98; p = 0.019) and 37-59 months (OR = 0.56; 95% CI = 0.49-0.63; p < 0.001), respectively, compared to the risk of anemia in children aged 6-12 months. Anemia was 28% less likely in children of non-anemic mothers (OR = 0.72; 95% CI = 0.66-0.80; p < 0.001) than children of anemic mothers. Children fed pumpkin, carrot, squash, and sweet potato showed a lower occurrence of anemia by 17% (OR = 0.83; 95% CI = 0.70-0.99; p = 0.036) compared to those who were not fed these vegetables. Chances of anemia increased by 14% in children who were fed white potatoes, white yams, manioc, cassava, and other root-based foods (OR = 1.14; 95% CI = 1.01-1.29; p = 0.036). CONCLUSION This study highlighted the impact of a plant-based diet on the high prevalence of childhood anemia in Nigeria. Therefore, reformation of dietary habits, the inclusion of nutritional supplements, and food-fortification programs with reductions in maternal anemia are recommended.

Abstract
The causes of undernutrition are often linked to inappropriate complementary feeding practices and poor households' access to water, sanitation and hygiene (WASH), but limited evidence exists on the combined effect of poor WASH and inappropriate complementary feeding practices on stunted child growth. We assessed the independent and joint contribution of inappropriate complementary feeding and poor WASH practices to stunted growth among children aged 6-23 months in the Jirapa Municipality of Ghana. A community-based cross-sectional analytical study design was used with a sample of 301 mothers/caregivers having children aged 6-23 months. The results indicate that in a multivariable logistic regression model that adjusted for confounders, children receiving both unimproved water and inappropriate complementary feeding had a higher and significant odd of becoming stunted (adjusted odds ratio = 33. 92; 95 % confidence interval 3⋅04, 37⋅17; P = 0⋅004) compared to households having both improved water sources and appropriate complementary feeding practices. Except for unimproved drinking water sources, poor sanitation and hygiene, which comprised the use of unimproved household toilet facilities, washing hands without soap and improper disposal of child faeces were not associated with the risks of stunting among children aged 6-23 months. The combined effect of unimproved water and inappropriate complementary feeding on stunting was greater than either unimproved water only or inappropriate complementary feeding only.

Abstract
Background: Stunting is a nutritional status based on measurements of the Length-for-Age or Height-for-Age index of the anthropometric standards assessment of nutritional status of children. The report of the Public Health Center (PHC) of Tegallalang I revealed the largest number of stunting cases in Kedisan Village, with 28 toddlers suffering from stunting based on 2017 data. Purpose: This study aims to investigate the risk factors associated with stunting at Kedisan Village, Tegallalang Sub-district, Gianyar District. Methods: This is an analytic study employing a case-control approach. Sampling was carried out using a total sampling technique; that is, by utilizing all cases of children under five who were declared stunted in the village in question (a total of 28 cases). The case:control ratio used was 1:1; thus, the total sample used in the study was 56 samples from May 2017. Bivariate analysis was conducted using a chi-square test. Results: The majority of respondents were employed (i.e., 67.80% in the case group and 53.50% in the control group); in terms of the most recent level of education, 35.70% of respondents in the case group had a junior high school education, while 46.40% in the control group had a senior high school education. The results of the bivariate analysis found that the risk factor that was most significantly related with the incidence of stunting was complementary foods with breast milk (p = 0.03; OR: 4.63), while other risk factors were not related to the occurrence of stunting. Conclusions: The factor that influenced the occurrence of stunting in Kedisan Village was complementary foods with breast milk.

Abstract
Congenital Heart Defects (CHDs) are associated with different patterns of malnutrition and growth retardation, which may vary worldwide and need to be evaluated according to local conditions. Although tetralogy of Fallot (TOF) is one of the first described CHDs, the etiology outcomes in growth and development of TOF in early age child is still unclear in most cases. This study was designed to investigate the growth retardation status of Chinese pediatric TOF patients under 5 years old. The body height, body weight and body mass index (BMI) of 262 pediatric patients (138 boys and 124 girls) who underwent corrective surgery for TOF between 2014 and 2018 were measured using conventional methods. The average body height, body weight and BMI of the patients were significantly lower than WHO Child Growth Standards, while the most affected was body height. Meanwhile, higher stunting frequency and greater deterioration of both the body height and weight happened in elder age (aged 13-60 months) rather than in infant stage (aged 0-12 months) among these patients. Our results confirmed that intervention should be given at early age to prevent the growth retardation of TOF patients getting severer.

Coastal urbanization influences human pathogens and microdebris contamination in seafood. THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 736:139081.

Abstract
Seafood is one of the leading imported products implicated in foodborne outbreaks worldwide. Coastal marine environments are being increasingly subjected to reduced water quality from urbanization and leading to contamination of important fishery species. Given the importance of seafood exchanged as a global protein source, it is imperative to maintain seafood safety worldwide. To illustrate the potential health risks associated with urbanization in a coastal environment, we use next-generation high-throughput amplicon sequencing of the 16S ribosomal RNA gene combined with infrared spectroscopy to characterize and quantify a vast range of potential human bacterial pathogens and microdebris contaminants in seawater, sediment and an important oyster fishery along the Mergui Archipelago in Myanmar. Through the quantification of >1.25 million high-quality bacterial operational taxonomic unit (OTU) reads, we detected 5459 potential human bacterial pathogens belonging to 87 species that are commonly associated with gut microbiota and an indication of terrestrial runoff of human and agricultural waste. Oyster tissues contained 51% of all sequenced bacterial pathogens that are considered to be both detrimental and of emerging concern to human health. Using infrared spectroscopy, we examined a total of 1225 individual microdebris particles, from which we detected 78 different types of contaminant materials. The predominant microdebris contaminants recovered from oyster tissues included polymers (48%), followed by non-native minerals (20%), oils (14%) and milk supplement powders (14%). Emerging technologies provide novel insights into the impacts of coastal development on food security and risks to human and environmental health.

A Systematic Review Investigating the Relation Between Animal-Source Food Consumption and Stunting in Children Aged 6-60 Months in Low and Middle-Income Countries. Adv Nutr 2019; 10:827-847. [PMID: 31177279 PMCID: PMC6743850 DOI: 10.1093/advances/nmz018] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Revised: 01/15/2019] [Accepted: 01/29/2019] [Indexed: 11/12/2022] Open
Abstract
Animal-source foods (ASFs) are a food group of interest for interventions aimed at reducing stunting and other inadequate growth measures in early childhood. The aim of this systematic review was to examine the relation between ASF consumption and stunting in children aged 6-60 mo in low- and middle-income countries (LMICs). The secondary aim was to examine the relation between ASF consumption and other indicators of growth and development (length/height, weight, head circumference, and anemia). A search of the peer-reviewed and grey literature published from January 1980 to June 2017 was conducted. Databases searched included CINAHL, Embase, Global Index Medicus, PubMed, and Web of Science. There were 14,783 records and 116 full text articles dual screened; 21 studies were included in the review and were dual evaluated for risk of bias (RoB). The relation between ASF and stunting (length- or height-for-age z-score←2) was examined in randomized-controlled trials [(RCTs), n = 3] and cross-sectional studies (n = 4) only; ASF reduced stunting in 1 RCT and was associated with reduced stunting in 1 cross-sectional study. We did not identify any longitudinal cohorts that examined this relation. The relation between ASF and secondary indicators length/height, weight, head circumference, and anemia were largely nonsignificant across study designs. The intervention/exposure, comparator, outcome measures, methods, and analyses were highly heterogeneous. Although we did not find a consistent relation between ASF consumption and our primary and secondary outcomes, this may have been a function of inconsistencies in study design. Foods in the whole diet, particularly combination dishes, are inherently difficult to assess. To quantitatively assess the relation between ASF and stunting and other indicators of growth and iron status in early childhood, future research should provide consistency in the definition and quantification of the exposure and outcomes allowing for interstudy quantitative comparisons.

Abstract
Anaemia is prevalent among preschool-aged children in Myanmar, but few epidemiological studies of anaemia at the national level were reported. Using data from the Myanmar Demographic and Health Survey 2015-2016, we examined risk factors for anaemia at household, maternal, and individual levels for children aged 6-23 months (n = 1,133) and 24-59 months (n = 2,393) separately. Survey design and sampling weights were adjusted for in multivariate regression analyses. The prevalence of anaemia was 77.2% in children aged 6-23 months and 50.8% in those aged 24-59 months. Living in geographic zones other than the hilly zone was associated with a higher odds of anaemia in both age groups (OR = 1.86-2.51 [95% lower limit > 1.0]). Maternal anaemia predicted child anaemia in a dose-response manner in both groups (6-23 months of age, OR = 2.01, 95% CI [1.38, 2.92; mild] and OR = 2.41, 95% CI [1.12, 5.19; moderate]; and 24-59 months of age, OR = 1.42, 95% CI [1.12, 1.81; mild] and OR = 2.92, 95% CI [1.91,4.46; moderate]). A maternal age of 14-24 years (ref: 25-34 years, OR = 1.67, 95% CI [1.06, 2.64]) and maternal tolerant attitude to domestic violence (OR = 1.61, 95% CI [1.13, 2.31]) predicted anaemia in children aged 6-23 months only. Younger child age (OR = 0.97, 95% CI [0.96, 0.98]), stunting (OR = 1.35, 95% CI [1.08, 1.69]) and using unimproved drinking water sources (OR = 1.38, 95% CI [1.10, 1.75]) were associated with anaemia in children aged 24-59 months. Consideration of age-specific risks factors for child anaemia will help in planning anaemia control programmes in Myanmar.

Abstract
The prevalence of childhood stunting in Myanmar is one of the highest among the countries of Southeast Asia. Cross-sectional data from the Myanmar Demographic Health Survey 2015-2016 were used to examine risk factors for stunting, wasting, and underweight among children aged 0-59 months. The prevalence of stunting, wasting, and underweight was 29.0%, 7.3%, and 19.2%, respectively. Accounting for sampling design and weights, multivariable logistic regression was conducted with 35 household, maternal, and child characteristics. Current pregnancy and maternal height <145 cm, home delivery, child's small birth size recalled by mother, and older age (ref: 0-5 months) predicted both stunting and underweight. Larger than average birth size was protective for all stunting, wasting, and underweight. Maternal body mass index <18.5 kg m-2 was a common risk factor for wasting and underweight. Lower wealth quintiles, maternal engagement in nonagricultural occupation, and male child predicted stunting only. Younger child age and not receiving vitamin A supplementation in the previous 6 months were risk factors for wasting only. Regional variation was also seen, with a higher odds of stunting in the West-South Region, North-East States, and West States, compared with the Central Regions. In Myanmar, socio-economic and demographic factors, poor maternal nutritional status, and living in certain geographical locations are affecting children's undernutrition. It is recommended that interventions for growth faltering focus on the first 1,000 days of life; optimum maternal nutrition be ensured during and before pregnancy and at adolescence; societal support be provided for mothers in poverty or engaged in nonagriculture; and region-specific undernutrition pathways be understood.

Public Health Nutr 2018; 21:3048-3057. [PMID: 30178732 PMCID: PMC6190069 DOI: 10.1017/s1368980018002173] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2018] [Revised: 04/30/2018] [Accepted: 07/31/2018] [Indexed: 11/07/2022]
Abstract
OBJECTIVE To investigate the socio-economic differentials underlying minimum dietary diversity (MDD) among children aged 6-23 months in three economically diverse South-East Asian countries. DESIGN The outcome variable MDD was defined as the proportion of children aged 6-23 months who received foods from four of the seven recommended food groups within the 24 h prior to interview. The association between socio-economic factors and MDD, adjusting for relevant characteristics, was examined using logistic regression. SETTING We used cross-sectional population data from recent Demographic and Health Surveys from Cambodia (2014), Myanmar (2015-16) and Indonesia (2012). SUBJECTS Total of 8364 children aged 6-23 months. RESULTS Approximately half of all children met the MDD, varying from 47·7 % in Cambodia (n 1023) to 58·2 % in Indonesia (n 2907) and 24·6 % in Myanmar (n 301). The likelihood (adjusted OR; 95 % CI) of meeting MDD increased for children in the richest households (Cambodia: 2·4; 1·7, 3·4; Myanmar: 1·8; 1·1, 3·0; Indonesia: 2·0; 1·6, 2·5) and those residing in urban areas (Cambodia: 1·4; 1·1, 1·9; Myanmar: 1·7; 1·2, 2·4; Indonesia: 1·7; 1·5, 1·9). MDD deprivation was most severe among children from the poorest households in rural areas. The association between mother's labour force participation and MDD was positive in all three countries but reached significance only in Indonesia (1·3; 1·1, 1·5). CONCLUSIONS MDD deprivation among young children was significantly high in socio-economically disadvantaged families in all three study settings. MDD requirements are not being met for approximately half of young children in these three South-East Asian countries.
