Health first, convenience second: Caregiver perspectives of commercially produced complementary foods in five Southeast Asian capital cities.

Caregivers in low- and middle-income countries increasingly feed commercially produced complementary foods (CPCF) to older infants and young children-shaped by factors including industry promotion. The dynamics of CPCF consumption and caregiver knowledge, attitudes and behaviours regarding complementary feeding practices are poorly understood in these settings. We examined how caregiver knowledge/attitudes/behaviours about CPCF shape the feeding of older infants and young children in the capital cities of five countries in Southeast Asia (Bangkok, Hanoi, Jakarta, Kuala Lumpur, Manila). An online, web-based, cross-sectional panel survey was conducted among mothers of a child aged 6-23 months. One hundred participants were included in each of the five capital cities. Questionnaires were undertaken in the official language of each city. Data were analysed in Stata (version 17.0), using χ2 tests to examine difference between variables of interest. All mothers purchased CPCF for their youngest child aged 6-23 months at the time of survey. CPCF were commonly fed to children at least once per day, and in many of the five cities at most or every feeding. While factors such as convenience and affordability influenced CPCF purchase, mothers primarily purchased CPCF for nutritional reasons. The most common source of feeding information was health care professionals, followed by social media. CPCF are ubiquitous in the diets of older infants and young children of educated middle-upper socioeconomic status mothers in capital cities of Southeast Asia, with perceived healthiness a key driver in selecting CPCF. A strong governmental regulatory response to industry marketing/promotion will be critical to addressing CPCF appropriateness, including health and nutritional claim use.

Effectiveness of optimized food-based recommendation promotion to improve nutritional status and lipid profiles among Minangkabau women with dyslipidemia: A cluster-randomized trial.

BACKGROUND: In women of Minangkabau ethnicity, a high prevalence of dyslipidemia, overweight, and obesity is thought to be closely related to poor dietary practices. Promotion of local specific food-based recommendations (FBRs) was previously found to be effective in improving dietary practice and nutrient intakes related to dyslipidemia. This study aimed to describe the effects of the FBR promotion on the nutritional status and lipid profiles of Minangkabau women with dyslipidemia. METHODS: We used a cluster-randomized design with a total subject of 123 Minangkabau women of reproductive age with dyslipidemia. They were recruited from 16 sub-villages and assigned to either the FBR group (n = 61) or the non-FBR group (n = 62). Data on body weight, height, waist circumference, and lipid profiles were collected at the baseline and the end of the trial. Linear mixed model analysis was used to analyze the effect of the intervention on nutritional status and lipid profiles. RESULTS: The mean effect (95% confidence interval) of the intervention on body weight, body mass index, and waist circumference for the FBR group versus the non-FBR group were -1.1 (-1.8; -0.39) kg, -0.43(-0.76; -0.11) kg/m2 and -2.1(-3.7;-0.46) mm respectively (p <0.05). The Castelli's index in the FBR group improved, but there was no significant between-group difference in the change of total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides at the end of the intervention. CONCLUSION: The promotion of the FBRs positively impact the nutritional status but did not significantly affect the blood lipid profile of Minangkabau women with dyslipidemia. TRIAL REGISTRATION: The trial was retrospectively registered at ClinicalTrials.gov Protocol Registration and Result System (PRS) as NCT04085874, in September 2019.

The impact of a package of behaviour change interventions on breastfeeding practices in East Java Province, Indonesia.

Suboptimal infant young child feeding practices are frequently reported globally, including in Indonesia. This analysis examined the impact of a package of behaviour change interventions on breastfeeding practices in Malang and Sidoarjo Districts, East Java Province, Indonesia. The BADUTA study (which in the Indonesian Language is an acronym for BAwah DUa TAhun, or children aged less than 2 years) was an impact evaluation using a cluster-randomized controlled trial with two parallel treatment arms. We conducted household surveys in 12 subdistricts from Malang and Sidoarjo. We collected information from 5175 mothers of children aged 0-23 months: 2435 mothers at baseline (February 2015) and 2740 mothers at endline (January to February 2017). This analysis used two indicators for fever and diarrhoea and seven breastfeeding indicators (early initiation of breastfeeding, prelacteal feeding, exclusive breastfeeding under 6 months, predominant breastfeeding, continued breastfeeding, age-appropriate breastfeeding and bottle-feeding). We used multilevel logistic regression analysis to assess the effect of the intervention. After 2 years of implementation of interventions, we observed an increased odds of exclusive breastfeeding under 6 months (adjusted odds ratio [aOR] = 1.85; 95% confidence interval [CI]: 1.35-2.53) and age-appropriate breastfeeding (aOR = 1.39; 95% CI: 1.07-1.79) in the intervention group than in the comparison group, at the endline survey. We found significantly lower odds for prelacteal feeding (aOR = 0.52; 95% CI: 0.41-0.65) in the intervention than in the comparison group. Our findings confirmed the benefits of integrated, multilayer behaviour change interventions to promote breastfeeding practices. Further research is required to develop effective interventions to reduce bottle use and improve other breastfeeding indicators that did not change with the BADUTA intervention.

Promotion of optimized food-based recommendations to improve dietary practices and nutrient intakes among Minangkabau women of reproductive age with dyslipidemia.

BACKGROUND AND OBJECTIVES: Using a linear programming approach, an optimized food-based recommendations (FBRs) had been formulated for Minangkabau women of reproductive age with dyslipidemia in Indonesia. This study aimed to assess the effectiveness of the promotion of the FBRs for improving dietary practices and nutrient intakes. METHODS AND STUDY DESIGN: A community-based, clustered-randomized trial was conducted among Minangkabau women of reproductive age (20-44 years) with dyslipidemia. The subjects were assigned either into the FBR group (n=48), or the non-FBR group (n=54). Baseline and end-line dietary data were assessed through interviews using a one-week semiquantitative food frequency questionnaire (SQ-FFQ) and two replicate 24-hour dietary recalls. The changes in dietary practice and nutrient intakes were analysed using ANCOVA test. RESULTS: Significant changes were observed (p<0.005) in the consumption of the promoted food items and subgroups (sea fish, soy protein, dark green leafy vegetables, and potatoes). Significant changes were also observed in nutrient intake, especially energy intake from carbohydrates and unsaturated fatty acids (total PUFA, MUFA, n-3 and n-6 fatty acids), as well as the dietary P/S ratio and fiber intake. CONCLUSIONS: With current dietary practices, intakes of some typical problem nutrients such as n-6, zinc, iron, and fiber still could not achieve 100% of the RNIs, while the intake of SFA still exceeded the recommended intake. Further approaches are needed to expand the population food basket and promote behavioral change to address established cultural food habits, including reducing the use of cooking oil in food preparation and increasing vegetable consumption.

A multicentre randomized controlled trial of food supplement intervention for wasting children in Indonesia-study protocol.

BACKGROUND: After the first six months of exclusive breastfeeding, children are introduced to liquids and semi-solid food, known as the complementary feeding phase. This phase is critical because it is often accompanied by improper feeding in children, which may lead to wasting and other nutrition problems. Fortified biscuits have been provided for wasting children as a nationwide programme. However, the ability of children to accept food supplementation remains questionable. This paper describes the protocol of a study investigating the efficacy of food supplementation (PMT biscuit) and nutrition education to improve the nutritional status of wasting children in Indonesia. METHOD: The efficacy of a government food supplementation programme will be examined using a randomized control trial design. Parents with wasting children aged 6-17 months will be recruited to participate in the study. After obtaining informed consent and pre-intervention measures, participants will be assigned into three arms of intervention with PMT biscuits and/or nutrition education only. The two primary outcomes for this study are the nutritional status of wasting children and PMT biscuit compliance. Characteristics of all subjects in each arm will be analysed and compared with each other to assess their comparability at the beginning. The data will be collected at pre-intervention, at 3 months of intervention, post-intervention, and at the 6- to 9-month follow up. DISCUSSION: This paper aims to describe the study protocol of a randomized controlled trial investigating the effects of different PMT biscuit portion and nutrition education in two arms and nutrition education only in another arm. This study is important because it will provide evidence for the Indonesian government regarding the efficacy of food supplementation and/or food-based recommendations to improve the nutritional status of wasting children aged 6-23 months in Indonesia. TRIAL REGISTRATION: The study has been registered at clinicaltrials.gov, maintained by the National Library of Medicine (NLM) at the National Institutes of Health (NIH), on April 26, 2018, and was last updated on April 30, 2018 (registration number: NCT03509155 ).

Realistic Food-Based Approaches Alone May Not Ensure Dietary Adequacy for Women and Young Children in South-East Asia.

Objectives Micronutrient deficiencies, in southeast Asia (SE Asia), remain a public health challenge. We evaluated whether promoting the consumption of locally available nutritious foods, which is a low-risk micronutrient intervention, alone can ensure dietary adequacy, for women of reproductive age and 6-23 m old children. Methods Representative dietary data from Cambodia, Indonesia, Lao PDR, Thailand and Vietnam were analysed using linear programming analysis to identify nutrients that are likely low in personal food environments (problem nutrients), and to formulate food-based recommendations (FBRs) for three to six target populations per country. Results The number of problem nutrients ranged from zero for 12-23 m olds in Indonesia, Thailand and Vietnam to six for pregnant women in Cambodia. The FBRs selected for each target population, if adopted, would ensure a low percentage of the population was at risk of inadequate intakes for five to ten micronutrients, depending on the country and target population. Of the 11 micronutrients modelled, requirements for iron, calcium and folate were most difficult to meet (≥ 10 of the 24 target populations), using FBRs alone. The number of individual FBRs selected per set, for each target population, ranged from three to eight; and often included meat, fish or eggs, liver/organ meats, vegetables and fruits. Conclusions for practice Intervention strategies need to increase access to nutritious foods, including products fortified with micronutrients, in SE Asia, when aiming to ensure dietary adequacy for most individuals in the population.

Nutritional potential of underutilized food crops to improve diet quality of young children in food insecure prone areas of Madura Island, Indonesia.

BACKGROUND AND OBJECTIVES: Attention is currently given to the nutrition potential of underutilized food crops; however, only few studies have focused on this potential for young children. We investigate the nutrient composition of selected underutilized food crops in Bangkalan District, Madura Island, Indonesia, to determine its potential in meeting the nutritional needs of young children during the complementary feeding period. METHODS AND STUDY DESIGN: We obtained data on the availability of underutilized food crops from a cross-sectional study conducted in 2014 in Bangkalan District, Indonesia, and nutrient composition primarily from the Indonesian Food Composition Database. We considered underutilized food crops to hold nutritional potential if they contributed at least 15% per 100 g edible portion recommended nutrient intake for children aged 6-11 months and 12-23 months or 5% recommended nutrient intake per 100 kcal for iron, zinc, calcium, niacin and folate. RESULTS: We identified nutritionally potential underutilized food crops from several food groups, including Sorghum bicolor, Canna edulis, Colocasia esculenta (the starchy roots and leaves), Plectranthus rotundifolius, Amorphophallus paeoniifolius, Moringa oleifera (the leaves and pods), Limonia acidissima, and Benincasa hispida-all of which can be utilized for formulating the complementary feeding diet of young children. CONCLUSIONS: In a food insecure area where malnutrition is prevalent, underutilized food crops have potential to improve the nutrient intake of young children in their complementary feeding period. These should be promoted through the creation of acceptable recipes and formulation of complementary feeding recommendations, which include these underutilized nutrient-dense crops.

Food-based recommendations for Minangkabau women of reproductive age with dyslipidemia.

BACKGROUND AND OBJECTIVES: Considering the impact of unfavorable dietary practices on inadequate nutrient intake, this cross-sectional study aimed to explore dietary practices, including problem nutrients, and develop local food-based recommendations (FBRs) to improve the intake of problem nutrients among women of reproductive age (WoRA) with dyslipidemia in Minangkabau, Indonesia. METHODS AND STUDY DESIGN: The study was conducted in the Padang township inhabited mostly by the Minangkabau tribe. Accordingly, 74 WoRA with dyslipidemia completed the study. Two replicate 24-h recalls and a 5-day food record were used to assess food consumption patterns. Then, linear programming (LP) analysis using three modules of the WHO Optifood software was employed to identify problem nutrients and develop FBRs. RESULTS: Median (5th and 95th percentiles) weekly consumption frequencies for grain; meat, fish, and eggs; and added fat were 18 (14-27), 11 (6-16), and 15 (7-30), while those for fruits and vegetables were 2 (0-11) and 7 (2-16), respectively. Based on the aforementioned food pattern, PUFA (both n-3 and n-6 fatty acids), dietary fiber, iron, and zinc were identified as typical problem nutrients. The final FBR emphasized on incorporating locally available nutrient-dense foods, as well as food groups and sub-groups, which would improve the intake of problem nutrients. CONCLUSIONS: Minangkabau WoRA have dietary practices that predispose them to dyslipidemia. Moreover, the LP approach is a sensitive tool for identifying nutrient-dense foods that could potentially improve problem nutrient intake, as well as those that need to be limited in the final FBR.

Dietary patterns of obese and normal-weight women of reproductive age in urban slum areas in Central Jakarta.

Developing countries including Indonesia imperatively require an understanding of factors leading to the emerging problem of obesity, especially within low socio-economic groups, whose dietary pattern may contribute to obesity. In this cross-sectional study, we compared the dietary patterns and food consumption of 103 obese and 104 normal-weight women of reproductive age (19-49 years) in urban slum areas in Central Jakarta. A single 24-h food recall was used to assess energy and macronutrient intakes (carbohydrate, protein and fat) and calculate energy density. A principal component analysis was used to define the dietary patterns from the FFQ. Obese women had significantly higher intakes of energy (8436·6 (sd 2358·1) v. 7504·4 (sd 1887·8) kJ (2016·4 (sd 563·6) v. 1793·6 (sd 451·2) kcal)), carbohydrate (263·9 (sd 77·0) v. 237·6 (sd 63·0) g) and fat (83·11 (sd 31·3) v. 70·2 (sd 26·1) g) compared with normal-weight women; however, their protein intake (59·4 (sd 19·1) v. 55·9 (sd 18·5) g) and energy density (8·911 (sd 2·30) v. 8·58 (sd 1·88) kJ/g (2·13 (sd 0·55) v. 2·05 (sd 0·45) kcal/g)) did not differ significantly. Two dietary patterns were revealed and subjectively named 'more healthy' and 'less healthy'. The 'less healthy' pattern was characterised by the consumption of fried foods (snacks, soyabean and roots and tubers) and meat and poultry products, whereas the more healthy pattern was characterised by the consumption of seafood, vegetables, eggs, milk and milk products and non-fried snacks. Subjects with a high score for the more healthy pattern had a lower obesity risk compared with those with a low score. Thus, obesity is associated with high energy intake and unhealthy dietary patterns characterised by consumption of oils and fats through fried foods and snacks.

Development of complementary feeding recommendations for 12-23-month-old children from low and middle socio-economic status in West Java, Indonesia: contribution of fortified foods towards meeting the nutrient requirement.

Inadequate nutrient intake as part of a complementary feeding diet is attributable to poor feeding practices and poor access to nutritious foods. Household socio-economic situation (SES) has an influence on food expenditure and access to locally available, nutrient-dense foods and fortified foods. This study aimed to develop and compare complementary feeding recommendations (CFR) for 12-23-month-old children in different SES and evaluate the contribution of fortified foods in meeting nutrient requirements. A cross-sectional survey was conducted in low and medium SES households (n 114/group) in urban Bandung district, West Java province, Indonesia. Food pattern, portion size and affordability were assessed, and CFR were developed for the low SES (LSES) and middle SES (MSES) using a linear programming (LP) approach; two models - with and without fortified foods - were run using LP, and the contribution of fortified foods in the final CFR was identified. Milk products, fortified biscuits and manufactured infant cereals were the most locally available and consumed fortified foods in the market. With the inclusion of fortified foods, problem nutrients were thiamin in LSES and folate and thiamin in MSES groups. Without fortified foods, more problem nutrients were identified in LSES, that is, Ca, Fe, Zn, niacin and thiamin. As MSES consumed more fortified foods, removing fortified foods was not possible, because most of the micronutrient-dense foods were removed from their food basket. There were comparable nutrient adequacy and problem nutrients between LSES and MSES when fortified foods were included. Exclusion of fortified foods in LSES was associated with more problem nutrients in the complementary feeding diet.

Folate and vitamin B12 status and dietary intake of anaemic adolescent schoolgirls in the delta region of Myanmar.

The aim of the present study was to assess the prevalence of deficiency of folate and vitamin B12 and, simultaneously, the nutrient intake adequacy of folate, vitamin B12, iron, vitamin A, vitamin C, vitamin B6 and calcium in 391 adolescent anaemic (Hb<120 g/l) schoolgirls living in the delta region of Myanmar (Burma). Dietary intakes were assessed using a 3 d estimated food record. The distribution of observed intakes calculated from the food records were adjusted for usual intakes, and the prevalence of inadequacy was estimated using the estimated average requirement cut-point method. Median (first, third quartile) serum folate and vitamin B12 concentrations were 6·5 (4·6, 8·5) nmol/l and 612·8 (443·2, 795·2) pmol/l, respectively. The prevalence of folate deficiency defined as <6·8 nmol/l was 54 %; however, vitamin B12 deficiency defined as <148 pmol/l was negligible (<1 %). The prevalence of inadequate intake of folate was high (100 %) as was the prevalence of inadequate intakes of vitamin A, vitamin C, vitamin B6 and calcium, ranging from 60 to 100 %. Red meat or poultry was rarely consumed, but fish was consumed on a daily basis. Green leafy vegetables were also consumed frequently but consumption of dairy products was uncommon. Folate deficiency was high, and the prevalence of inadequate intake of folate among other key micronutrients was relatively common in this sample of anaemic adolescent schoolgirls. Appropriate strategies such as food fortification and dietary diversification are needed to improve the micronutrient status of these young women to ensure optimal health and future reproductive success.

Local food-based complementary feeding recommendations developed by the linear programming approach to improve the intake of problem nutrients among 12-23-month-old Myanmar children.

Poor feeding practices result in inadequate nutrient intakes in young children in developing countries. To improve practices, local food-based complementary feeding recommendations (CFR) are needed. This cross-sectional survey aimed to describe current food consumption patterns of 12-23-month-old Myanmar children (n 106) from Ayeyarwady region in order to identify nutrient requirements that are difficult to achieve using local foods and to formulate affordable and realistic CFR to improve dietary adequacy. Weekly food consumption patterns were assessed using a 12-h weighed dietary record, single 24-h recall and a 5-d food record. Food costs were estimated by market surveys. CFR were formulated by linear programming analysis using WHO Optifood software and evaluated among mothers (n 20) using trial of improved practices (TIP). Findings showed that Ca, Zn, niacin, folate and Fe were 'problem nutrients': nutrients that did not achieve 100 % recommended nutrient intake even when the diet was optimised. Chicken liver, anchovy and roselle leaves were locally available nutrient-dense foods that would fill these nutrient gaps. The final set of six CFR would ensure dietary adequacy for five of twelve nutrients at a minimal cost of 271 kyats/d (based on the exchange rate of 900 kyats/USD at the time of data collection: 3rd quarter of 2012), but inadequacies remained for niacin, folate, thiamin, Fe, Zn, Ca and vitamin B6. TIP showed that mothers believed liver and vegetables would cause worms and diarrhoea, but these beliefs could be overcome to successfully promote liver consumption. Therefore, an acceptable set of CFR were developed to improve the dietary practices of 12-23-month-old Myanmar children using locally available foods. Alternative interventions such as fortification, however, are still needed to ensure dietary adequacy of all nutrients.

The influence of vitamin A status on iron-deficiency anaemia in anaemic adolescent schoolgirls in Myanmar.

OBJECTIVE: The present study was conducted to investigate reasons for the high prevalence of anaemia among adolescent schoolgirls and to elucidate the role of vitamin A in contributing to Fe-deficiency anaemia (IDA). DESIGN: Among 1269 schoolgirls who were previously screened for anaemia (Hb < 120 g/l), 391 anaemic girls were further assessed for Fe, vitamin A and subclinical inflammation status. Fe and vitamin A indicators were corrected for inflammation and were compared in the Fe-deficient and non-deficient groups as well as between those with and without inflammation. Logistic regression was done to determine whether vitamin A status and subclinical inflammation were risk factors for Fe deficiency. The differences in Fe status among tertiles of vitamin A concentrations were assessed using ANOVA. SETTING: Myanmar. SUBJECTS: Adolescent schoolgirls (n 391). RESULTS: One-third of the anaemia (30·4%) was IDA. Prevalence of low vitamin A status (serum retinol <1·05 µmol/l) was 31·5%. Fe and vitamin A status were significantly different between the IDA and non-IDA groups and also based on their inflammation status. Logistic regression showed that low vitamin A status was a significant predictor for being Fe deficient (OR = 1·81; 95% CI 1·03, 3·19 and OR = 2·31; 1·31, 4·07 in the middle (1·056-1·298 µmol/l) and low (≤1·056 µmol/l) vitamin A tertiles, respectively). ANOVA showed that better Fe status was associated with a higher concentration of serum retinol but only in IDA. CONCLUSIONS: Fe deficiency was not the main cause of anaemia in the present population. The role of vitamin A as well as other micronutrients should be taken into account in addressing the problem of anaemia.

Relationship between household expenditures on strategic foods and prevalence of undernutrition among children 0 to 23 months of age in Indonesia.

BACKGROUND: The global economic crisis in 2007/08 resulted in higher food prices, which increased household food expenditures while worsening the quantity and quality of food consumed, potentially leading to child undernutrition. OBJECTIVE: To characterize the relationship of the mean proportions of household expenditures on strategic foods with the prevalence of undernutrition (high stunting, wasting, and underweight) among children under 2 years of age in Indonesia. METHODS: The study used data from 437 districts from two nationally representative surveys conducted in 2007, the National Socioeconomic Survey (Susenas) and the Basic Health Research (Riskesdas). RESULTS: A higher mean proportion of household expenditure on soybeans was significantly associated with lower odds (3rd vs. 1st tertile) of prevalence of high wasting (OR, 0.51; 95% CI, 0.28 to 0.94; p =.031) and high underweight (OR, 0.09; 95% CI, 0.03 to 0.28; p < .0001). A lower mean proportion of household expenditure on sugar and cooking oil was significantly associated with lower odds of prevalence of high wasting (OR, 2.41; 95% CI, 1.37 to 4.23; p = .002) and high underweight (2nd vs. 1st tertile) (OR, 2.38; 95% CI, 1.05 to 5.41; p = .039). CONCLUSIONS: Among all strategic foods, a higher proportion of household expenditure on soybeans and a lower proportion of household expenditure on sugar and cooking oil are associated with lower odds of high wasting and underweight prevalence among children 0 to 23 months of age. The results indicate the need for promotion of consumption of fermented soybeans and education aiming at decreasing expenditure on sugar and cooking oil to increase consumption of more nutritious foods.

Complementary feeding recommendations based on locally available foods in Indonesia.

BACKGROUND: Affordable, locally contextual complementary feeding recommendations (CFRs) that take into account cultural diversity and differences in food availability will be more likely to result in long-term improvements in complementary feeding practices than general recommendations. More objective approaches, such as linear programming (LP), have been recommended to identify optimal but CFRs to meet nutrient requirements given local food availability, food patterns, food portions, and cost. OBJECTIVE: To present results of our previous studies in which we developed CFRs using LP and to provide an example of how these CFRs can be put into practice in a community intervention trial in Indonesia. METHODS: Dietary data were obtained using single 24-hour dietary recall or 1-day weighed diet record combined with 1-day 24-hour recall and 5-day food intake tally. With the use of the LP approach, nutrient intakes were optimized while ensuring that a realistic diet was selected by using constraints such as the diet's energy content, food patterns, food portions, and cost. The price per 100 g of edible portion was obtained from market surveys in two or three local markets in each study area. LP analysis was performed using Super Solver in MS Excel or Optifood software. RESULTS: Iron, zinc, calcium, and niacin were problem nutrients in all age groups of children (6 to 8, 9 to 11, and 12 to 23 months) in both rural and periurban areas, except among children of higher socioeconomic status in urban areas. Thiamin and folate were also problem nutrients found in some settings. Animal-source foods (meat, fish, poultry, and eggs [MFPE] and fortified foods were the nutrient-dense foods identified by LP to fill the nutrient gaps of these problem nutrients. CONCLUSIONS: Iron, calcium, zinc, niacin, and potentially folate and thiamine are typical "problem nutrients" in complementary foods of Indonesian children. However, the extent of dietary inadequacy varies across age groups, area, and socioeconomic level. MFPE and fortified foods can improve micronutrient adequacy in complementary feeding diets and should be promoted in CFRs.

Hepcidin profile of anemic adolescent schoolgirls in Indonesia at the end of 12 weeks of iron supplementation.

BACKGROUND: Iron deficiency is still the major nutritional problem in the developing world, and iron supplementation remains one of the most effective intervention strategies. Hepcidin, a newly discovered iron regulatory hormone, is an acute phase protein, and its role in iron supplementation has not been well explored. OBJECTIVE: To investigate the hepcidin profiles of anemic adolescent girls who had received weekly iron supplementation. METHODS: A cross-sectional study was conducted at the end of iron supplementation among adolescent schoolgirls (n = 83) in Pramuka Island, Indonesia. All the girls were anemic at the beginning and received 60 mg of elemental iron twice weekly for 12 weeks. Hemoglobin, hepcidin, serum ferritin, and red cell parameters were measured, together with inflammation markers. RESULTS: At the end of the 12-week supplementation, 65.1% (n = 64) of the girls were no longer anemic, but 43.4% (n = 36) were still iron deficient. The rate of subclinical inflammation, measured by C-reactive protein (CRP) and alpha-1-acid glycoprotein (AGP), was 38.6% (n = 32). Hepcidin was not correlated with either ferritin or red cell parameters. There was no association between hepcidin and the inflammatory markers CRP and AGP. The mean hepcidin concentration was 42.9 +/- 17.9 ng/mL and was not significantly different between anemic and nonanemic girls (44.2 +/- 14.9 and 42.3 +/- 19.2 ng/mL, respectively; p = .708). However, hepcidin concentration was slightly higher in the iron replete-group than in the iron-deficient group (45.2 +/- 20.0 and 39.3 +/- 13.5 ng/mL, respectively), a suggestive trend that did not reach statistical significance (p = .218). CONCLUSIONS: Hepcidin concentrations tended to be higher among the subset of girls who responded poorly to iron supplementation as a consequence of increased subclinical inflammation. A longitudinal study should be conducted to explore the role of hepcidin in iron supplementation.

Epigenetic studies in children at risk of stunting and their parents in India, Indonesia and Senegal: a UKRI GCRF Action Against Stunting Hub protocol paper.

INTRODUCTION: In 2020, an estimated 150 million children under the age of 5 years were stunted. Stunting results from early-life adversity and it is associated with significant physical and cognitive deficit, lifelong socioeconomic disadvantage and reduced life expectancy. There is a need to understand the causes of stunting and its effects in order to develop strategies to avoid it and to mitigate the consequences once stunting has occurred. Epigenetics is an important mechanism through which early-life factors are thought to influence biological function, with long-term consequences. We describe a series of epigenetic studies designed to understand how early-life adversity results in stunting and to inform the development of practical tools such as predictive markers and therapeutic targets. This work is part of the UKRI GCRF Action Against Stunting Hub. METHODS AND ANALYSIS: The project-in India, Indonesia and Senegal-comprises an observational study of mothers, fathers, and offspring (n=500) spanning the first 1000 days of life, and an intervention study in each country. Epigenetic status (DNA methylation) is determined in saliva from babies collected within 1 month of birth and again at 18 months of age, and from mothers and fathers around the time of birth. Epigenome-wide analysis is carried out using the Illumina EPIC array, augmented by high-definition sequencing approaches. Statistical analysis is carried out at the level of candidate genes/regions, higher dimensional epigenetic states and epigenome-wide association. Data analysis focuses on the determinants of stunting, the effectiveness of interventions, population comparisons and the link between epigenetics and other thematic areas, which include anthropometry, microbiome, gut health, parasitology, cognition, nutrition, food hygiene and water sanitation, food systems and the home environment. ETHICS AND DISSEMINATION: This study has been approved by the relevant Ethics Committees in Indonesia, India and Senegal, and the UK. Research data will be published and posted in public repositories.

Understanding the role of household hygiene practices and foodborne disease risks in child stunting: a UKRI GCRF Action Against Stunting Hub protocol paper.

INTRODUCTION: Environmental hygiene and food safety are important determinants of child stunting. This research aims to explore the relationship between child stunting and household hygiene practices and behaviours, including the availability of water, sanitation and hygiene (WASH) facilities; the use of safe food and good quality drinking water (especially when used for complementary feeding); hygienic practices in food transport, storage and preparation and the control of cross-contamination from animals, their produce and waste. METHODS AND ANALYSIS: This study is part of a wider observational study which aims to investigate the interdisciplinary factors contributing to child stunting using a 'whole child' paradigm. The observational study recruits women during pregnancy in Hyderabad, India, Lombok, Indonesia and Kaffrine, Senegal, and dyads (ie, 500 mother-infant pairs per country) are followed longitudinally up to 24 months after birth. Within the interdisciplinary niche, the study here has developed tools to investigate the potential exposure pathways to environmental pathogen contamination of foods and water. Holistic WASH and food safety data collection tools have been developed to explore exposure pathways at the household level, including: (1) survey questionnaires; (2) spot-checks; (3) biological sampling of drinking water, food and domestic surfaces and (4) direct observation. An integrated analytical approach will be used to triangulate the evidence in order to examine the relationships between child stunting, WASH and food safety behaviours. ETHICS AND DISSEMINATION: Ethical approval of the study was granted by the ethics committee of the LSHTM, RVC, ILRI, ICMR, IIPHG, SEAMEO-RECFON, University of Cheikh Anta Diop. Findings of the study will be disseminated through publication in peer-reviewed journals, relevant international conferences, public engagement events, and policy-maker and stakeholder events.

Investigating market-based opportunities for the provision of nutritious and safe diets to prevent childhood stunting: a UKRI-GCRF action against stunting hub protocol paper.

BACKGROUND: Inadequate access to affordable, safe, desirable and convenient nutrient-dense food is one of the underlying causes of child stunting. While targeted nutrition-sensitive interventions (eg, backyard 'nutri-gardens') may increase dietary diversity within farming households, such interventions have limited scalability across the wider food system where markets remain underdeveloped. This research aims to develop and assess market-based interventions for key nutrient-dense foods to help improve the diets of women and children in the first 1000 days of life. METHODS: Data collection uses four parallel approaches in each of the three study countries (India, Indonesia and Senegal). (1) A novel food environment tool will be developed to characterise the accessibility and affordability of nutrient-dense foods in the study countries. The tool will be validated through pretesting using cognitive interviewing and piloting in purposively sampled households, 10 (cognitive interviewing) and 30 (piloting) households in each country; (2) stakeholder interviews (eg, with producers, intermediaries and retailers) will be conducted to map out nutrition-sensitive entry points of key value chains (eg, animal-sourced foods), before hotspots of potential food safety hazards will be identified from food samples collected along the chains; (3) the Optifood and Agrifood tools will be used to identify foods that can address food system nutrient gaps and engage key stakeholders to prioritise market interventions to improve nutrition outcomes. Optifood and Agrifood parameters will be informed by publicly available data, plus interviews and focus groups with value chain stakeholders; (4) informed by the previous three approaches and a campaign of participatory 'group model building', a novel system dynamics model will evaluate the impact of alternative market-based solutions on the availability and affordability of nutrient-dense foods over time. ETHICS AND DISSEMINATION: The study has received ethical approval in the United Kingdom, Senegal, Indonesia and India. Dissemination comprises peer-reviewed journals, international disciplinary conferences and multistakeholder dissemination workshops.

Assessment of the role of gut health in childhood stunting in a multisite, longitudinal study in India, Indonesia and Senegal: a UKRI GCRF Action Against Stunting Hub protocol.

INTRODUCTION: Childhood stunting has a complex aetiology, with poor gut health being an important contributor. This study will assess inter-relationships between maternal and infant gut health indices and infant linear growth. Inter-relationships between gut health indices, systemic inflammation and growth hormones in early childhood will also be assessed. METHODS AND ANALYSIS: A longitudinal observational study of cohorts of 600 newborns and their mothers in India, Indonesia and Senegal will be conducted. Women will be recruited during pregnancy and their children followed up to age 24 months. Stool, urine and blood samples will be collected from the women and children for assessments of helminthic and protozoal parasites, bacterial pathogens, faecal microbiota taxa, biomarkers of environmental enteric dysfunction, systemic inflammation and growth hormones. Child anthropometric measurements will be collected at birth and at ages 3, 6, 9, 12, 18 and 24 months. The gut health indices will be integrated with cohort data from other Action Against Stunting Hub (AASH) workstreams for interdisciplinary analyses of childhood stunting and the development of a new typology of stunting. DISCUSSION: This study will advance scientific understanding of the role of gut health in childhood stunting and will contribute to a broader knowledge of the complex aetiology of this condition as part of the interdisciplinary AASH research to reduce the global burden of childhood stunting. ETHICS AND DISSEMINATION: This study has been approved by the relevant Ethics Committees in Senegal, India, and Indonesia and LSHTM. The results will be submitted for publication in peer-reviewed journals.
