South East Asian Nutrition Surveys II (SEANUTS II) Thailand: Triple burden of malnutrition among Thai children aged 6 months to 12 years.

OBJECTIVE: This study assessed nutritional status among Thai children using anthropometry, dietary intakes, and micronutrient status. DESIGN: Cross-sectional survey with multi-stage cluster sampling. Body weight and height were measured in all children. Dietary intakes were assessed using 24-hour dietary recall. Biochemical assessment was performed in one-third of the children. SETTING: The study was conducted in Thailand's four geographical regions and Bangkok. PARTICIPANTS: 3478 Thai children aged 0.5-12.9 years. RESULTS: Stunting showed a downward trend by age group and was most prevalent among infants and toddlers. Overweight and obesity showed a significant upward trend by age group, location, and sex, and was highest among children aged 7-12.9 years. Risks of inadequate micronutrient intakes (calcium, iron, zinc, vitamins A, C, and D) were high (53.2-93.6%). Prevalence of zinc and mild vitamin A deficiencies were low; vitamin D and B12 deficiencies were nil. Vitamin D insufficiency was significantly higher in the urban area and among girls aged 7-12.9 years. Anemia was very high in infants and toddlers (56.6 and 35.2%), but showed a significant downward trend by age group. There was an overall high prevalence of iron deficiency without anemia (25%) versus iron deficiency anemia (4.2%) among children aged 4-12.9 years old. CONCLUSIONS: The high prevalence of stunting and anemia among children aged 1-3.9 years and overweight and obesity among children aged 7-12.9 years requires continued attention. While prevalence of biochemical micronutrient deficiencies was not high (except for iron), high prevalence of dietary inadequacies for several micronutrients warrants further in-depth investigations.

Discordance in exclusive breastfeeding between maternal recall and deuterium dose-to-mother technique during the first 6 months of infants: A multi-country study in Asia.

PURPOSE: This study aimed to assess the agreement in EBF between maternal recall and the dose-to-mother (DTM) technique. METHODS: Indonesia, Malaysia, Mongolia, Pakistan, Sri Lanka, Thailand, and Vietnam participated in the study. A total of 207 and 118 mother-infant pairs were assessed at 3 and 6 months of child's age. Using a standardized questionnaire, mothers were asked to recall child feeding during the previous 24 h, at 3 and 6 months. Those recalled to be EBF proceeded to be assessed using DTM technique. Non-milk oral intake (NMOI) cutoff of 86.6 g/d was used to classify EBF. RESULTS: According to DTM, 66% of infants were EBF at 3 months, while only 22% were EBF at 6 months. At 3 months, the overall % agreement between maternal recall and DTM method was 68%, kappa 0.06 (95% CI: 0.07-0.20), and at 6 months, the % agreement was only 21%, kappa -0.031 (95% CI -0.168 to 0.107). Human milk intakes were similar at 3 months and 6 months when expressed as g/d, but decreased when expressed as g/kg/d, with a large variation within and between countries; Pakistan being the lowest. CONCLUSION: This study showed there were declining levels of EBF from 3 to 6 months in the participating countries from Asia and the agreement between maternal recall and DTM technique to classify EBF was low. To ensure that the DTM technique can be more widely used in evaluating breastfeeding promotion programs, consensus on the appropriate NMOI cutoff and simplification of the DTM protocol is necessary.

Performance of the Global Diet Quality Score (GDQS) App in Predicting Nutrient Adequacy and Metabolic Risk Factors among Thai Adults.

BACKGROUND: The Global Diet Quality Score (GDQS) was developed for monitoring nutrient adequacy and diet-related noncommunicable disease risk in diverse populations. A software application (GDQS app) was recently developed for the standardized collection of GDQS data. The application involves a simplified 24-h dietary recall (24HR) where foods are matched to GDQS-food groups using an onboard database, portion sizes are estimated at the food group level using cubic models, and the GDQS is computed. OBJECTIVES: The study aimed to estimate associations between GDQS scores collected using the GDQS app and nutrient adequacy and metabolic risks. METHODS: In this cross-sectional study of 600 Thai males and nonpregnant/nonlactating females (40-60 y), we collected 2 d of GDQS app and paper-based 24HR, food-frequency questionnaires (FFQs), anthropometry, body composition, blood pressure, and biomarkers. Associations between application scores and outcomes were estimated using multiple regression, and application performance was compared with that of metrics scored using 24HR and FFQ data: GDQS, Minimum Dietary Diversity-Women, Alternative Healthy Eating Index-2010, and Global Dietary Recommendations score. RESULTS: In covariate-adjusted models, application scores were significantly (P < 0.05) associated with higher energy-adjusted mean micronutrient adequacy computed using 24HR (range in estimated mean adequacy between score quintiles 1 and 5: 36.3%-44.5%) and FFQ (Q1-Q5: 40.6%-44.2%), and probability of protein adequacy from 24HR (Q1-Q5: 63%-72.5%). Application scores were inversely associated with BMI kg/m2 (Q1-Q5: 26.3-24.9), body fat percentage (Q1-Q5: 31.7%-29.1%), diastolic blood pressure (Q1-Q5: 84-81 mm Hg), and a locally-developed sodium intake score (Q1-Q5: 27.5-24.0 points out of 100); positively associated with high-density lipoprotein cholesterol (Q1-Q5: 49-53 mg/dL) and 24-h urinary potassium (Q1-Q5: 1385-1646 mg); and inversely associated with high midupper arm circumference (Q5/Q1 odds ratio: 0.52) and abdominal obesity (Q5/Q1 odds ratio: 0.51). Significant associations for the application outnumbered those for metrics computed using 24HR or FFQ. CONCLUSIONS: The GDQS app effectively assesses nutrient adequacy and metabolic risk in population surveys.

Breastfeeding duration is associated with higher adiposity at 6-8 months of age.

Breastfeeding (BF) has been identified as a protective factor against childhood obesity. However, evidence of the association between BF duration and adiposity remains inconclusive. Few studies have been conducted among Southeast Asian infants that have measured body composition during infancy using the gold standard stable isotope method. This study aimed to evaluate the association between BF duration and body composition during infancy. Healthy full-term Thai infants aged 6-8 months (n = 60) receiving exclusive or predominant BF for at least 3 months were recruited. Skinfold thickness (SFT) was measured by well-trained investigators. Body composition was assessed by the deuterium dilution technique. Infants with longer BF duration (>6 months; mean 7.5 ± 0.5 months, n = 29) had a higher subscapular SFT z-score than those with shorter BF duration (≤6 months; mean 5.3± 0.9 months, n = 31) by 0.48 (95% confidence interval [CI]: 0.01-0.94). After adjustment for age and sex, BF duration and age at introduction of complementary feeding (CF) were positively associated with fat mass and fat mass index at 6-8 months. One month increase in BF duration and CF age was associated with a 0.37 (95% CI: 0.05, 0.69) kg/m2 and 0.76 (95% CI: 0.18, 1.34) kg/m2 increase in the fat mass index, respectively. After adjusting for infant body mass index (BMI) during the earlier infancy period, the strength of the association was attenuated. This finding may reflect reverse causality where infants with lower BMI received formula or CF earlier. A longitudinal study with follow-up into childhood is warranted to confirm the effects of BF on adiposity in infancy and childhood.

Zinc and iron adequacy and relative importance of zinc/iron storage and intakes among breastfed infants.

Neonatal nutrient storage and supplies from breast milk contribute to nutrient status and growth of infants during their early life. This study investigated the adequacy of zinc and iron intakes among breastfed infants during the first 4 months and determined the relative importance of zinc/iron storage versus nutrient intakes with infant's biochemical status and growth. A longitudinal study followed lactating women and their breastfed infants from birth to 4 months postpartum. Cord zinc and ferritin concentrations, as indicators of nutrient storages, were determined. Zinc and iron intakes from breast milk were determined by measurement of breast milk volume together with milk zinc and iron concentrations at 2 and 4 months postpartum. Inadequacy of nutrient intakes was determined using average requirement (AR) which were 1.6 and 0.24 mg/day for zinc and iron respectively. Infant's serum zinc and ferritin were determined at 4 months of age. The data were collected from 64 and 56 participants at 2 months and 4 months postpartum. Inadequate zinc intake was found in 14.5 and 40% of infants at 2 and 4 months old, respectively. The prevalence of biochemical zinc and iron deficiency in infants were 76 and 11%, respectively. Iron endowment was significantly associated with serum ferritin at 4 months. The cumulative zinc intake was positively associated with weight gain and weight-for-length Z-score, but not length. This study provides quantitative data on zinc and iron intakes, and demonstrates the relative importance of nutrient storage versus intakes on biochemical status and growth of breastfed infants.

Effect of Maternal Nutritional Status and Mode of Delivery on Zinc and Iron Stores at Birth.

Zinc and iron deficiencies among infants aged under 6 months may be related with nutrient store at birth. This study aimed to investigate the association between zinc and iron stores at birth with maternal nutritional status and intakes during pregnancy. 117 pregnant women were enrolled at the end of second trimester and followed until delivery. Clinical data during pregnancy, including pre-pregnancy body mass index (BMI) and at parturition were collected from medical record. Zinc and iron intakes were estimated from a food frequency questionnaire. Serum zinc and ferritin were determined in maternal blood at enrollment and cord blood. Mean cord blood zinc and ferritin were 10.8 ± 2.6 µmol/L and 176 ± 75.6 µg/L, respectively. Cord blood zinc was associated with pre-pregnancy BMI (adj. ß 0.150; p = 0.023) and serum zinc (adj. ß 0.115; p = 0.023). Cord blood ferritin was associated with pre-pregnancy BMI (adj. ß -5.231; p = 0.009). Cord blood zinc and ferritin were significantly higher among those having vaginal delivery compared to cesarean delivery (adj. ß 1.376; p = 0.007 and 32.959; p = 0.028, respectively). Maternal nutritional status and mode of delivery were significantly associated with zinc and iron stores at birth. Nutrition during preconception and pregnancy should be ensured to build adequate stores of nutrients for infants.

Double burden of malnutrition and its association with infant and young child feeding practices among children under-five in Thailand.

OBJECTIVE: This study examined the prevalence of stunting-overweight and socio-demographic determinants among children under-five years of age, as well as associations with infant and young child feeding (IYCF) among children aged 6-23 months. DESIGN: Secondary data analysis based on the Thailand Multiple Indicator Cluster Survey 2015-2016. SETTING: Cross-national study. PARTICIPANTS: Nationally representative sample of children under-five years of age (n 12 313). RESULTS: The prevalence of wasting, stunting, overweight and stunting-overweight was 5·3, 10·5, 10·1 and 1·6 %, respectively. In multivariate analyses, children under 6 months, children from low and middle wealth tertiles, and children living in rural areas were prone to being wasted. Male children, low wealth tertile and a non-Thai speaking household head were positively and children aged 48-59 months and a one-child household were inversely associated with stunting. Children from a low wealth tertile were less likely to be overweight, while older age, male children and children from a one-child household were more likely to be overweight. Stunting-overweight was associated with children aged 24-47 months, male children, mothers having secondary education, a one-child household, a non-Thai speaking household head and an urban area. In terms of IYCF indicators, despite no association with stunting and stunted-overweight children, current breast-feeding and inadequate meal frequency were associated with being wasting, while current breast-feeding and dietary diversity were inversely associated with being overweight. CONCLUSIONS: This study revealed the double burden of malnutrition at the individual and population levels among Thai children under-five, which calls for concrete integrated interventions to tackle all forms of malnutrition.

Determining the Actual Zinc and Iron Intakes in Breastfed Infants: Protocol for a Longitudinal Observational Study.

BACKGROUND: Zinc and iron deficiencies among breastfed infants during the first 6 months of life have been reported in previous studies. The amounts of zinc and iron intakes from breast milk are factors that contribute to the zinc and iron status of breastfed infants. OBJECTIVE: This study aims to quantitatively determine zinc and iron intakes by breastfed infants during the first 4 months of life and to investigate the factors that predict zinc and iron status in breastfed infants. METHODS: Pregnant women at 28 to 34 weeks of gestation were enrolled. Zinc and iron status during pregnancy was assessed. At delivery, cord blood was analyzed for zinc and iron levels. Participants and their babies were followed at 2 and 4 months postpartum. Maternal dietary intakes and anthropometric measurements were performed. The amount of breast milk intake was assessed using the deuterium oxide dose-to-mother technique. Breast milk samples were collected for determination of zinc and iron levels. The amount of zinc and iron consumed by infants was calculated. Zinc and iron status was determined in mothers and infants at 4 months postpartum. RESULTS: A total of 120 pregnant women were enrolled, and 80 mother-infant pairs completed the study (56 provided full breastfeeding, and 24 provided breast milk with infant formula). All data are being managed and cleaned. Statistical analysis will be done. CONCLUSIONS: This study will provide information on zinc and iron intakes in exclusively breastfed infants during the first 4 months of life and explore predictive factors and the possible association of zinc and iron intakes with infant growth and nutrient status.

Iodine Supplementation in Mildly Iodine-Deficient Pregnant Women Does Not Improve Maternal Thyroid Function or Child Development: A Secondary Analysis of a Randomized Controlled Trial.

Background: Iodine deficiency during pregnancy may be associated with lower offspring IQ, but there are few data on the safety and efficacy of maternal iodine supplementation on child development. In a previously reported multi-center randomized trial conducted in Thailand and India, we assessed the effect of iodine supplementation in mildly iodine-deficient pregnant women on offspring development. In this secondary analysis of that trial, we report data only from the Thai pregnant women in the study, who were more iodine deficient at entry. Methods: Pregnant women in Bangkok, Thailand, were randomized to receive daily 200 µg oral iodine or placebo until delivery. We assessed thyroid size and thyroid function during pregnancy and cognitive and motor development at ages 1, 2, and 5.7 years. The trial was registered at www.clinicaltrials.gov/NCT00791466. Findings: Women (n = 514) entered the trial between November 2008 and March 2011 at a mean ± SD gestational age of 11 ± 2.8 weeks; their median (IQR) UIC was 112 (75, 170) µg/L. Mean compliance with supplementation was 88%. We assessed 397 mothers in the 3rd trimester, 231 infants at age 2 y, and 157 children at mean age 5.7 y. During pregnancy, there was a slightly greater decrease in free and total thyroxine concentrations in the iodine group (p < 0.05). At age 2 years, the iodine group had borderline lower scores for combined fine and gross motor function (p = 0.05), but there were no other significant differences in development. At 5.7 years, there were no significant group differences in child development. Conclusion: Daily iodine supplementation in mildly iodine deficient pregnant women was associated with small negative effects on maternal thyroxine concentrations, but did not affect child development. The safety and efficacy of iodine supplementation in mildly-iodine deficient pregnant women needs to be evaluated further in large randomized controlled trials.

Human Milk Intake of Thai Breastfed Infants During the First 6 Months Using the Dose-to-Mother Deuterium Dilution Method.

BACKGROUND: Data on infant human milk intakes in low- and middle-income countries are limited, although the deuterium oxide dose-to-mother method (DTM) is an accurate tool for its estimation. OBJECTIVE: We assessed human milk intakes of Thai infants during the first 6 months comparing exclusive breastfeeding (EBF), predominant breastfeeding (PBF), and partial breastfeeding (PartBF). METHODS: One hundred and ten healthy Thai lactating mother-infant pairs were followed from birth. Human milk intakes were determined at 6 weeks, 3 months, and 6 months using the DTM method. Daily energy and protein intakes were assessed using 3-day nonconsecutive 24-hour recalls. Sociodemographic characteristics were collected using a questionnaire. To compare breastfeeding practices, one-way analysis of variance with Tukey post hoc test assessed normally distributed data, while the Kruskal-Wallis test with Mann-Whitney U test was used for not normally distributed data. RESULTS: No difference existed in human milk intakes during the first 6 months between EBF (743-776 g/d) and PBF (748-862 g/d). Human milk intakes of PartBF infants were significantly lower compared to other infants. Human milk intake was sufficient to meet infant energy and protein requirements during the first 3 months for EBF and PBF groups. Infant formula largely replaced human milk during the first 3 months; other solid foods were also introduced among the PartBF infants. CONCLUSIONS: Human milk intakes were comparable between EBF and PBF infants during the first 6 months and provided adequate energy and protein to meet requirements. Infant formula largely replaced breast milk among PartBF infants, although other foods were also given early. This study was registered at clinicaltrials.gov as NCT04020640.

Nutrition education in Southeast Sulawesi Province, Indonesia: A cluster randomized controlled study.

This study evaluated the impact of a nutrition education intervention on child feeding practices and children's nutritional status. Using a randomized controlled trial, we conducted an intervention for 6 months among caregivers with children aged 6-17 months in two subdistricts of Kendari, SE Sulawesi Province, Indonesia. In all, 22 integrated health posts were randomly assigned to an educational intervention or control group with 266 participants in both groups. Participants in the intervention group attended four nutrition classes and received a monthly home visit by cadres (community volunteers), whereas participants in the control group only received standard monthly health care at the health post. The primary study outcome was children's dietary diversity scores (DDSs). Mixed model analysis was conducted to examine the intervention effects on DDS and children's growth adjusting for clustering within subvillages. The study showed the educational intervention had a significant effect on children's DDS. Children in the intervention group had a larger DDS compared with children in the control group (Beta [mean difference] = 0.34, 95% CI: 0.02 to 0.66, P = 0.038). The intervention effect on height-for-age z-score (HAZ) could not be shown (Beta = 0.24, 95% CI: -0.06 to 0.56, P = 0.112). However, stunting prevalence remained stable in the intervention group but increased in the control group. These results indicated nutrition education delivered through nutrition classes combined with regular home visits by cadres as influencers provided a great potential to be adopted to complement other nutrition programmes in community health centres.

Rural-urban differences in socioeconomic inequality trends for double burden of malnutrition in Thailand 2005-2016.

BACKGROUND/OBJECTIVES: This study determined time trends in the prevalence of malnutrition and its socioeconomic inequality among children under five at a national level and by urbanity in Thailand. SUBJECTS/METHODS: This study compared malnutrition prevalence and inequality among children under five by wealth index score and urbanity using three Multiple Indicator Cluster Surveys for 2005-06, 2012, and 2015-16. The magnitude of inequality was measured on absolute (slope index of inequality) and relative scales (relative index of inequality). RESULTS: National prevalence of stunting decreased substantially (16% in 2005-06 and 2012 and 10% in 2015-16), whereas overweight prevalence did not meaningfully change. Inequalities in stunting and overweight by wealth decreased over time nationally on both absolute and relative scales (p-trend < 0.001). Similar decreasing patterns in inequalities were seen in both rural and urban areas, though substantial inequalities persisted. Poor children remained stunted (11.6% in the rural poor and 14.8% in the urban poor), wasted (6.6% in the rural poor), and, strikingly, also overweight (from 5.5% in 2005-06 to 9% in 2015-16 for the rural poor and 8% over time for the urban poor). CONCLUSION: Despite favorable time trends in socioeconomic inequality, this study showed the existence of a double burden of malnutrition (under-nutrition and overweight) in young Thai children with persistent inequalities at the national level. Different patterns of this double burden were seen between urban and rural areas. Public health policies should target both under-nutrition and overweight and consider urbanity in this rapidly developing society.

Multi-criteria Mapping of Stakeholders' Viewpoints in Five Southeast Asian Countries on Strategies to Reduce Micronutrient Deficiencies Among Children and Women of Reproductive Age: Findings from the SMILING Project.

BACKGROUND: Despite scientific evidence on the potential impact or importance of specific interventions to improve micronutrient status of vulnerable groups, political commitment and extensive support from national stakeholders is paramount to support introduction and implementation of these interventions at national level. In order to develop efficient nutritional strategies to improve the micronutrient status of children < 5 years of age and women of reproductive age that will be supported by a wide range of stakeholders, a better understanding of viewpoints on the nutrition politics and strategies is necessary. Multi-criteria mapping (MCM) was successfully used to assess the stakeholder's viewpoint in a wide variety of contexts since the late 1990s. OBJECTIVE: The objective of the present study was to assess the viewpoints of stakeholders on a wide range of potential nutritional interventions in the five Southeast Asian countries participating in the SMILING project. METHOD: MCM methodology was used to appraise the stakeholder's viewpoints in five countries. RESULTS: The results show that the overall stakeholders' preference was for actions already implemented in their country rather than for new, innovative options, even for supplementation. Indirect interventions such like food fortification (except in Indonesia), delayed cord clamping or food-based approaches were generally less favored by the stakeholders. However, the majority of stakeholders agreed that new approaches should be considered and put in place in the future provided that evidence of their impact was demonstrated, that they received adequate technical support for their implementation and their monitoring, and that they will be accompanied by strong advocacy among decision-makers, civil society and beneficiaries. CONCLUSIONS FOR PRACTICE: To conclude, for the introduction of new, innovative strategies to reduce micronutrient deficiencies in South-East Asia, convincing stakeholders appears to be the first hurdle to be taken.

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.

Health Workers' and Villagers' Perceptions of Young Child Health, Growth Monitoring, and the Role of the Health System in Remote Thailand.

BACKGROUND: In Thailand, despite widespread improvements in child nutrition, stunting is still highly prevalent among northern hill tribe children. OBJECTIVE: To understand how villagers and health workers (volunteers and officials) gauge health of children younger than 5 years, whether growth monitoring is salient, and the relationships of villagers with the health system in this remote location. METHODS: Qualitative research was undertaken with 8 hill tribe villages. A workshop on infant and young child health and nutrition was held with 8 village health volunteers, 2 per village, selected by a public health officer. In-depth interviews were conducted with 20 villagers and 2 volunteers who had children 0 to 5 years. Eight other health workers were also interviewed. All dialogue was conducted in Thai through bilingual facilitators and recorded, transcribed, and translated into English. Transcripts were coded and analyzed thematically within and across participant groups. RESULTS: Overall, villagers considered strength and independence of children to be hallmarks of health; the size of children featured rarely. Volunteers did not perceive local benefits of growth monitoring, and the extent of child malnutrition was unclear to them. Nutrition counseling was seldom mentioned by villagers or health workers. Across all accounts, and considering silences, relationships of villagers with the health system seemed fragile. CONCLUSION: Villagers understand child health in terms of functional abilities rather than size. Volunteer health workers in this remote location have limited resources and support. Together this helps explain why, against a background of poverty and food insecurity, growth monitoring does not translate to improvements in child nutrition.

Local perspectives and context in relation to feeding practices of children under 2 years in the mountain villages of northern Thailand.

OBJECTIVE: To gain an in-depth understanding of infant and young child feeding practices, accompanying beliefs and their sociocultural context in the Karen and Lua ethnic communities of northern Thailand. DESIGN: A two-day workshop and thirty in-depth interviews were undertaken in June 2014. Dialogue occurred with the assistance of translators and was recorded, transcribed and translated. A detailed thematic analysis was undertaken. SETTING: Northern Thai indigenous communities in which one-third of the children under 5 years of age are stunted. SUBJECTS: People with various roles in the local health system and twenty-six villagers who cared for infants and young children. RESULTS: Predominant breast-feeding was said to occur for 1 to 3 months but was not exclusive due to early introduction of water and/or rice. Exclusive breast-feeding for 6 months was impeded by the need for mothers to return to farming work, with the early introduction of solids enabling infants to be cared for by other family members. Low variety in complementary foods was typical during infancy, with few local foods having appropriate texture and special preparation of foods rarely described. A pervasive underlying issue is women's responsibility to labour and lack of time to care for their young children. Poverty and food insecurity also featured in participants' accounts. CONCLUSIONS: In combination, women's limited time to care, poverty and food insecurity are perpetuating poor nutrition of children in early life. Agricultural solutions that are being explored should also attend to the burden of work for women.

The Use of Multivitamin/Multimineral Supplements: A Modified Delphi Consensus Panel Report.

PURPOSE: Evidence supporting the use of dietary supplements, in particular, multivitamin/multimineral supplements (MVMS), has been mixed, complicating the ability of health care professionals to recommend their use. To clarify the role that MVMS can play in supporting human health, a series of consensus statements was developed based on expert opinion. METHODS: A panel of 14 international experts in nutritional science and health care was convened to develop consensus statements related to using MVMS in supporting optimal human health. The modified Delphi process included 2 rounds of remote voting and a final round of voting at a roundtable meeting where evidence summaries were presented and discussed. The level of agreement with each of 9 statements was rated on a 5-point Likert scale: agree strongly; agree with reservation; undecided; disagree; or disagree strongly. Consensus was predefined as ≥80% of the panel agreeing strongly or agreeing with reservation to a given statement. FINDINGS: Consensus was reached for all statements. The panel determined that MVMS can broadly improve micronutrient intakes when they contain at least the micronutrients that are consumed insufficiently or have limited bioavailability within a specified population. MVMS formulations may also be individualized according to age, sex, life cycle, and/or other selected characteristics. There are specific biological processes and health outcomes associated with deficient, inadequate, and adequate micronutrient levels. Adequate intake is necessary for normal biological functioning required for good health; in some instances, higher than recommended micronutrient intakes have the potential to provide additional health benefits. Meeting daily intakes established by dietary reference values should be an explicit public health goal for individuals and populations. Use of MVMS is one approach to ensure that adequate micronutrient needs are met in support of biological functions necessary to maintain health. Long-term use of MVMS not exceeding the upper limit of recommended intakes has been determined to be safe in healthy adults. There is insufficient evidence to indicate that MVMS are effective for the primary prevention of chronic medical conditions, including cardiovascular disease and cancer. However, for certain otherwise healthy subpopulations (eg, pregnant women, older adults) and some individuals with existing medical conditions who experience inadequacies in micronutrient intake, addressing inadequacies by using MVMS can provide health benefits. IMPLICATIONS: This consensus panel has described key issues related to the use of MVMS among individuals at risk of or presenting with inadequacies in micronutrient intake or biomarker status.

Tools to improve planning, implementation, monitoring, and evaluation of complementary feeding programmes.

Adequate nutrient intake is a prerequisite for achieving good nutrition status. Suboptimal complementary feeding practices are a main risk factor for stunting. The need for systematic and user-friendly tools to guide the planning, implementation, monitoring, and evaluation of dietary interventions for children aged 6-23 months has been recognized. This paper describes five tools, namely, ProPAN, Optifood, Cost of the Diet, Fill the Nutrient Gap, and Monitoring Results for Equity System that can be used in different combinations to improve situation analysis, planning, implementation, monitoring, or evaluation approaches for complementary feeding in a particular context. ProPAN helps with development of strategies and activities designed to change the behaviours of the target population. Optifood provides guidance for developing food-based recommendations. The Cost of the Diet can provide insight on economic barriers to accessing a nutritious and balanced diet. The Fill the Nutrient Gap facilitates formulation of context-specific policies and programmatic approaches to improve nutrient intake, through a multistakeholder process that uses insights from linear programming and secondary data. The Monitoring Results for Equity System helps with analysis of gaps, constraints, and determinants of complementary feeding interventions and adoption of recommended practices especially in the most vulnerable and deprived populations. These tools, and support for their use, are readily available and can be used either alone and/or complementarily throughout the programme cycle to improve infant and young child-feeding programmes at subnational and national levels.

Effect of iodine supplementation in pregnant women on child neurodevelopment: a randomised, double-blind, placebo-controlled trial.

BACKGROUND: Iodine deficiency during pregnancy might be associated with reduced intelligence quotient (IQ) score in offspring. We assessed the effect of iodine supplementation in mildly iodine-deficient pregnant women on neurodevelopment of their offspring in areas where schoolchildren were iodine sufficient. METHODS: In this randomised, placebo-controlled trial, pregnant women in Bangalore, India, and Bangkok, Thailand, were randomly assigned (1:1) to receive 200 µg iodine orally once a day or placebo until delivery. Randomisation was done with a computer-generated sequence and stratified by site. Co-primary outcomes were verbal and performance IQ scores on the Wechsler Preschool and Primary Scale of Intelligence Third Edition (WPPSI-III) and the global executive composite score from the Behaviour Rating Inventory of Executive Function-Preschool Version (BRIEF-P) in the children at age 5-6 years. The trial was double-blinded; some unmasking took place at age 2 years for an interim analysis, but participants and nearly all investigators remained masked to group assignment until age 5-6 years. Analysis was by intention to treat using mixed-effects models. This trial is registered with ClinicalTrials.gov, number NCT00791466. FINDINGS: Between Nov 18, 2008, and March 12, 2011, 832 women entered the trial at a mean gestational age of 10·7 weeks (SD 2·7); median urinary iodine concentration was 131 µg/L (IQR 81-213). Mean compliance with supplementation was 87%, assessed by monthly tablet counts. 313 children (iodine group, n=159; placebo group, n=154) were analysed for verbal and performance IQ with WPPSI-III and 315 (iodine group, n=159; placebo group, n=156) for overall executive function with BRIEF-P. Mean WPPSI-III scores for verbal IQ were 89·5 (SD 9·8) in the iodine group and 90·2 (9·8) in the placebo group (difference -0·7, 95% CI -2·9 to 1·5; p=0·77), and for performance IQ were 97·5 (12·5) in the iodine group and 99·1 (13·4) in the placebo group (difference -1·6, -4·5 to 1·3; p=0·44). The mean BRIEF-P global executive composite score was 90·6 (26·2) in the iodine group and 91·5 (27·0) in the placebo group (difference -0·9, -6·8 to 5·0; p=0·74). The frequency of adverse events did not differ between groups during gestation or at delivery: 24 women in the iodine group and 28 in the placebo group reported adverse events (iodine group: abortion, n=20; blighted ovum, and n=2; intrauterine death, n=2; placebo group: abortion, n=22; blighted ovum, n=1; intrauterine death, n=2; early neonatal death, n=1; and neonatal death, n=2). INTERPRETATION: Daily iodine supplementation in mildly iodine-deficient pregnant women had no effect on child neurodevelopment at age 5-6 years.

Body mass index is associated with fat mass in normal, overweight/obese, and stunted preschool children in central Thailand.

BACKGROUND AND OBJECTIVES: Body mass index (BMI) is widely used as a surrogate measure of adiposity. The relationship between BMI and body fatness varies by race, sex, and age and more variations have been found among children. This study investigated the relationship between BMI and fat mass among 3-5 year old children having different nutritional status. METHODS AND STUDY DESIGN: A cross-sectional study was conducted in 15 daycare centers in central Thailand. 137 healthy preschool children were recruited according to their nutritional status: thin [BMI for age Z scores, (BAZ) <-2 SD], normal BMI (-2 SD<= BAZ <=+2 SD), overweight/obese (BAZ >+2 SD), and stunted [height for age Z scores < -2 SD]. Fat-free mass was determined by deuterium dilution technique. Fat mass (FM) in kilograms (TFM) and in percentage (FM%), and fat mass index (FMI, FM/height2) were calculated. RESULTS: FM and FMI were the highest in the overweight/obese groups. In the thin group, girls had higher FMI compared to boys (3.2 vs 2.8 kg/m2, p<0.05). The relationship between BMI with FMI and FM differed by nutritional status. BMI was more strongly associated with FMI, TFM, and FM% in the overweight/ obese (r=0.97, 0.95, 0.80, p<0.05) and the normal (r=0.88, 0.84, 0.68, p<0.05) groups but not in the stunted group, and inconsistent in the thin group. CONCLUSIONS: The inconsistency in the relationship between BMI and body fatness suggests that BMI is appropriate for reflecting adiposity in normal and overweight/obese children, but not undernourished preschool children.
