RESUMEN
OBJECTIVE: The study's objective was to investigate multiple underlying social, economic and agricultural determinants of stunting among under-five children in three distinct ecological areas in rural Myanmar. DESIGN: Repeated cross-sectional surveys in three states of Myanmar. SETTING: Rural households in Chin (mountainous), Magway (plains) and Ayeyarwady (delta). PARTICIPANTS: From two purposively selected adjacent townships in each state, we randomly selected twenty villages and, in each village, thirty households with under-five children. Households in the first survey in 2016 were revisited in late 2017 to capture seasonal variations. RESULTS: Stunting increased from 40·4 % to 42·0 %, with the highest stunting prevalence in Chin state (62·4%). Univariate Poisson regression showed factors contributing to child stunting varied across the regions. Adjusted Poisson regression models showed that child's age and short maternal stature (aRR = 1·14 for Chin, aRR = 1·89 for Magway and aRR = 1·86 for Ayeyarwady) were consistently associated with child stunting across three areas. For Chin, village-level indicators such as crop consumption (aRR = 1·18), crop diversity (aRR = 0·82) and land ownership (aRR = 0·89) were significantly associated with stunting. In Magway, the number of household members (aRR = 1·92), wealth status (aRR = 0·46), food security status (aRR = 1·14), land ownership (aRR = 0·85) and in Ayeyarwady, women's decision-making (aRR = 0·67) and indicators related to hygiene (aRR = 1·13) and sanitation (aRR = 1·45) were associated with stunting. CONCLUSIONS: Area-specific factors were associated with stunting. Maternal short stature and child age were consistent determinants of stunting. A multi-sectoral local approach, including improvements in transport, is needed to address the intergenerational malnutrition problem.

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.

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 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.

OBJECTIVE: To assess oil consumption, vitamin A intake and retinol status before and a year after the fortification of unbranded palm oil with retinyl palmitate. DESIGN: Pre-post evaluation between two surveys. SETTING: Twenty-four villages in West Java. SUBJECTS: Poor households were randomly sampled. Serum retinol (adjusted for subclinical infection) was analysed in cross-sectional samples of lactating mothers (baseline n 324/endline n 349), their infants aged 6-11 months (n 318/n 335) and children aged 12-59 months (n 469/477), and cohorts of children aged 5-9 years (n 186) and women aged 15-29 years (n 171), alongside food and oil consumption from dietary recall. RESULTS: Fortified oil improved vitamin A intakes, contributing on average 26 %, 40 %, 38 %, 29 % and 35 % of the daily Recommended Nutrient Intake for children aged 12-23 months, 24-59 months, 5-9 years, lactating and non-lactating women, respectively. Serum retinol was 2-19 % higher at endline than baseline (P<0·001 in infants aged 6-11 months, children aged 5-9 years, lactating and non-lactating women; non-significant in children aged 12-23 months; P=0·057 in children aged 24-59 months). Retinol in breast milk averaged 20·5 µg/dl at baseline and 32·5 µg/dl at endline (P<0·01). Deficiency prevalence (serum retinol <20 µg/dl) was 6·5-18 % across groups at baseline, and 0·6-6 % at endline (P≤0·011). In multivariate regressions adjusting for socio-economic differences, vitamin A intake from fortified oil predicted improved retinol status for children aged 6-59 months (P=0·003) and 5-9 years (P=0·03). CONCLUSIONS: Although this evaluation without a comparison group cannot prove causality, retinyl contents in oil, Recommended Nutrient Intake contributions and relationships between vitamin intake and serum retinol provide strong plausibility of oil fortification impacting vitamin A status in Indonesian women and children.

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.

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.

Marfan syndrome (MFS) is a hereditary condition caused by mutations in the FBN1 gene. Genetic mutations in the FBN1 locus impact the function of the encoded protein, Fibrillin 1, a structural molecule forming microfibrils found in the connective tissue. MFS patients develop severe cardiovascular complications including thoracic aortic aneurysm and aortic dissection, which predispose them to an enhanced risk of premature death. Here, we generated two induced pluripotent stem cell (iPSC) lines harboring mutations in the FBN1 gene (p.C1942C>A and c.1954 T>C), directly derived from MFS patients. We have shown that both iPSC lines displayed expression of pluripotency markers, normal karyotype and ability of trilineage differentiation, representing a valuable tool for the identification of new therapeutic strategies for intervening in this disease.

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.

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.

INTRODUCTION: Monitoring, Evaluation and Learning (MEL) is an integral part of research, programme and policy development and implementation. However, MEL methods used to monitor and evaluate interdisciplinary research projects are often informal and under-reported. This article describes the MEL protocol of the UKRI GCRF Action Against Stunting Hub (AASH). METHODS AND ANALYSIS: The AASH conducts interdisciplinary research into childhood stunting in India, Indonesia and Senegal across 23 distinct work packages. Project-specific MEL framework and methods will be implemented. A logframe will be developed to monitor and evaluate the research activities across the field sites including the number of participants recruited, questionnaires, measurements and procedures completed. MEL dashboards using Tableau and Glasscubes will be used to track and report progress, milestones and outcomes of the project. Dashboard outputs will be reported as numbers and percentages, with additional graphs/charts for easy visualisation. A 'learning' framework will be developed to outline appropriate pipelines for the dissemination of the research findings. This includes a theory of change explicating the overarching ambitions of the project in influencing policy, practice and research, and strategic engagement of relevant stakeholders to evaluate knowledge, attitudes and best practices for impactful engagement and dissemination of the research findings. ETHICS AND DISSEMINATION: Ethical approval was granted by the Ethics Committee of the London School of Hygiene & Tropical Medicine (17915/RR/17513); National Institute of Nutrition (ICMR)-Ministry ofâ¯Health and Family Welfare, Government of India (CR/04/I/2021); Health Research Ethics Committee, University of Indonesia and Cipto Mangunkusumo Hospital (KET-887/UN2.F1/ETIK/PPM.00.02/2019); and the National Ethics Committee for Health Research (CNERS), Senegal (Protocole SEN19/78). Findings from this work will be published in peer-reviewed journals, presented in conferences and disseminated to policy makers and research communities.

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.

INTRODUCTION: Child stunting has a complex aetiology, especially in the first 1000 days of life. Nutrition interventions alone have not produced expected impacts in reducing/preventing child stunting, indicating the importance of understanding the complex interplay between environmental, physiological and psychological factors influencing child nutritional status. This study will investigate maternal and child nutrition, health and well-being status and associated factors through the assessment of: (1) anthropometry, (2) biomarkers of nutrition and health status, (3) dietary intakes, (4) fetal growth and development, (5) infant morbidity, (6) infant and young child feeding (IYCF) and (7) perinatal maternal stress, depression and social support. METHODS: This study will be conducted in a prospective pregnancy cohort in India, Indonesia and Senegal. Pregnant women will be recruited in the second (Indonesia, Senegal) and third (India) trimester of pregnancy, and the mother and infant dyads followed until the infant is 24 months of age. During pregnancy, anthropometric measures will be taken, venous blood samples will be collected for biochemical assessment of nutrition and health status, dietary intakes will be assessed using a 4-pass-24-hour dietary recall method (MP24HR), fetal ultrasound for assessment of fetal growth. After birth, anthropometry measurements will be taken, venous blood samples will be collected, MP24HR will be conducted, infant morbidity and IYCF practices will be assessed and a sample of breastmilk will be collected for nutrient composition analyses. Perinatal maternal stress, depression, social support and hair cortisol levels (stress) will be measured. The results from this study will be integrated in an interdisciplinary analysis to examine factors influencing infant growth and inform global efforts in reducing child stunting. ETHICS AND DISSEMINATION: Ethical approval was granted by the Ethics Committee of the London School of Hygiene and Tropical Medicine (17915/RR/17513); National Institute of Nutrition (ICMR)-Ministry of Health and Family Welfare, Government of India (CR/04/I/2021); Health Research Ethics Committee, University of Indonesia and Cipto Mangunkusumo Hospital (KET-887/UN2.F1/ETIK/PPM.00.02/2019); and the Comité National d'Ethique pour la Recherche en Santé, Senegal (Protocole SEN19/78); the Royal Veterinary College (URN SR2020-0197) and the International Livestock Research Institute Institutional Research Ethics Committee (ILRI-IREC2020-33). Results will be published in peer-reviewed journals and disseminated to policy-makers and participating communities.

Background: Children's growth is essential to nutritional status and population health. In 2015, 18.9% of under-five children in Myanmar were underweight, and only 25% of 6-23-month-old children had the minimum dietary diversity (MDD). Objectives: We conducted this study to assess the association between mother's dietary diversity score (DDS) and underweight among under-five children. Materials and Methods: This study analyzed data from the "Livelihood and Food Security Survey," a cross-sectional study conducted in 2016 in rural areas in Chin State, Magway, and Ayeyarwady regions. It included 2029 under-five children and used underweight as an outcome variable. We calculated DDSs for mothers of under-five children using the MDD-women methodology. The prevalence of underweight and MDD were estimated. A multivariable binary logistic regression analysis estimated odds ratios and 95% confidence intervals (CIs). Results: The overall prevalence of underweight was 26.3% (95% CI: 23.4, 29.3), and that of the mother with a MDD score was 29.2% (95% CI: 26.0, 32.8). Multivariable binary logistic regression analysis showed that the prevalence of underweight in children was higher if maternal MDD was not met (adjusted odds ratio = 1.41; 95% CI: 1.05, 1.89). Conclusions: The children's age, types of toilets, and region were independent predictors of being underweight. Underweight among under-five children and diverse food consumption among their mothers are critical public health challenges in rural Myanmar that require urgent action. Nutrition education for rural communities should focus on feeding children with locally available diverse foods.

Duchenne muscular dystrophy (DMD) is an X-linked recessive disorder that leads to death in early adulthood. Patients with DMD have null mutations leading to loss of functional dystrophin protein. Here we generated two DMD induced pluripotent stem cell (iPSC) lines, one with deletion of exon 51 and the other with a single nucleotide nonsense mutation (c.10171C > T). Both lines expressed high levels of pluripotency markers, had the capability of differentiating into derivatives of the three germ layers, and possessed normal karyotypes. These iPSC lines can serve as powerful tools to model DMD in vitro and as a platform for therapeutic development.

Specific mutations in the TTR gene are responsible for the development of variant (hereditary) ATTR amyloidosis. Here, we generated two human induced pluripotent stem cell (iPSC) lines from patients diagnosed with Transthyretin Cardiac Amyloidosis (ATTR-CM) carrying heterozygous mutation in the TTR gene (i.e., p.Val30Met). The patient-derived iPSC lines showed expression of high levels of pluripotency markers, trilineage differentiation capacity, and normal karyotype. The generation of these iPSC lines represents a great tool for modeling patient-specific amyloidosis in vitro, allowing the investigation of the pathological mechanisms related to the disease in different cell types and tissues.

Germline pathogenic variants in the BRCA2 gene are strongly correlated with an elevated risk of developing breast cancer. Two specific BRCA2 variants, c.8167G>C (p.Asp2723His) and c.1583del (p.Asn528fs), have been identified from individuals with a family history of breast cancer. Here we generated two iPSC lines from breast cancer patients who are heterozygous carriers of these two variants. These iPSCs exhibit pluripotency and demonstrate the capability to differentiate into three germ layers. These iPSC lines represent a valuable resource for personalized pre-clinical research, offering new opportunities to explore the underlying mechanisms of breast cancer and develop targeted therapeutic approaches.

Dietary patterns high in fibre and green leafy vegetables have shown an inverse association with lower risks of type 2 diabetes mellitus and improved glycaemic control. The study aimed to investigate the effects of increased vegetable intake and conventional diabetes diet on glycaemic control among type 2 diabetic patients. White-collar workers from one telecommunication company with type 2 diabetes were assigned to two treatment groups by cluster randomisation. Individuals with known type 2 diabetes and poor glycaemic control (HbA1c ≥8 g%) were eligible and a total of 84 subjects were recruited. Subjects in the intervention group (n 41) were offered to attend seminars and intensive coaching weekly to encourage them to increase raw vegetable intake. The control group (n 40) followed the conventional diet according to the guidelines of the Indonesian Society of Endocrinology. Glycated haemoglobin (HbA1c), plasma lipids, blood pressure, vegetable intake and anthropometric measurements were assessed at baseline and end line of 12 weeks intervention. A regression analysis was conducted using differences in HbA1C between baseline and 12 weeks as the dependent variable. Student's t test was conducted for the changes of biochemical indicators from baseline to end line during the period of 12 weeks intervention. Glycaemic control improved in the intervention group and mean HbA1C, fasting blood glucose and post-prandial blood glucose in the intervention group decreased significantly along with body weight, waist circumference and total cholesterol. The finding suggested that the intervention which emphasised raw vegetable intake contributed to improved glycaemic control among Indonesian adults with type 2 diabetes mellitus.

The need for a multisectoral approach to tackle stunting has gained attention in recent years. Baduta project aims to address undernutrition among children during their first 1000 days of life using integrated nutrition-specific and nutrition-sensitive interventions. We undertook this cohort study to evaluate the Baduta project's effectiveness on growth among children under 2 years of age in two districts (Sidoarjo and Malang Districts) in East Java. Six subdistricts were randomly selected, in which three were from the intervention areas, and three were from the control areas. We recruited 340 pregnant women per treatment group during the third trimester of pregnancy and followed up until 18 months postpartum. The assessment of breastfeeding and complementary feeding practices used standard infant and young child feeding (IYCF) indicators in a tablet-based application. We measured weight and length at birth and every three-months after that. The enumerators met precision and accuracy criteria following an anthropometry standardization procedure. Among the breastfed children, the percentage of children who achieved the minimum dietary diversity score (DDS) and minimum acceptable diet (MAD) was higher for the intervention group than the comparison group across all age groups. The odd ratios were 3.49 (95% CI: 2.2-5.5) and 2.79 (95% CI: 1.7-4.4) for DDS and 3.49 (95% CI: 2.2-5.5) and 2.74 (95% CI: 1.8-5.2) for MAD in the 9-11 month and 16-18-month age groups, respectively. However, there was no significant improvement in growth or reduction in the prevalence of anemia. The intervention was effective in improving the feeding practices of children although it failed to show significant improvement in linear growth of children at 18 months of age.
