Associations between Zinc and Hemoglobin Concentrations in Preschool Children and Women of Reproductive Age: An Analysis of Representative Survey Data from the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) Project.

Background: Anemia is a worldwide concern. Nutritional deficiencies and inflammation are considered main contributors, but zinc deficiency has only recently been associated with anemia.

Objectives: In this study we assessed associations between zinc status and hemoglobin (Hb) concentrations and anemia in preschool children 6-59 mo old (PSC) and nonpregnant women of reproductive age 15-49 y old (WRA) in population-based nutrition surveys.

Caretakers' perceptions and willingness-to-pay for complementary food in urban and rural Cambodia.

Inadequate child nutrition during the first '1000 days' is widespread in Cambodia, resulting in a high prevalence of child malnutrition. Access to processed complementary food in packages (PCFP) may support caretakers in improving diet of young children. This study aimed to evaluate the caretakers' preferences and willingness-to-pay (WTP) for PCFP in Cambodia.

Multi-Micronutrient Fortified Rice Improved Serum Zinc and Folate Concentrations of Cambodian School Children. A Double-Blinded Cluster-Randomized Controlled Trial.

Background: Within Cambodia, micronutrient deficiencies continue to be prevalent in vulnerable groups, such as women and children. Fortification of staple foods such as rice could be a promising strategy for Cambodia to improve micronutrient status.

Objective: Our objective was to investigate the impact of multiple-micronutrient fortified rice (MMFR), distributed through a World Food Program school-meals program (WFP-SMP) on serum zinc concentrations and folate status in a double-blind, cluster-randomized, placebo-controlled trial.

Micronutrient deficiencies and their public health implications for South-East Asia.

Purpose Of Review: Micronutrient deficiencies are highly prevalent worldwide, including in South-East Asia, and have a profound impact on public health. Most efforts towards eliminating micronutrient deficiencies have focused on vitamin A, iron, and iodine deficiency. But deficiency of other micronutrients also affect public health.

Stunting, wasting and breast-feeding as correlates of body composition in Cambodian children at 6 and 15 months of age.

The study aimed at assessing stunting, wasting and breast-feeding as correlates of body composition in Cambodian children. As part of a nutrition trial (ISRCTN19918531), fat mass (FM) and fat-free mass (FFM) were measured using 2H dilution at 6 and 15 months of age. Of 419 infants enrolled, 98 % were breastfed, 15 % stunted and 4 % wasted at 6 months.

Interventions to Improve Micronutrient Status of Women of Reproductive Age in Southeast Asia: A Narrative Review on What Works, What Might Work, and What Doesn't Work.

Objectives To provide an overview of nutrition-specific and nutrition-sensitive interventions that could improve micronutrient status of women of reproductive age. Methods This narrative review has a special focus on Southeast Asia, as the work was undertaken within the framework of the SMILING (Sustainable Micronutrient Interventions to controL deficiencies and Improve Nutrition status and General health in Southeast Asia) project. Results In order for new interventions to become accepted, comprehension and interpretation of potential impact of different strategies by policymakers and non-nutritionists is needed.

Effect of complementary food with small amounts of freshwater fish on whole blood n-3 fatty acids in Cambodian infants age 6-15 months.

The impact of freshwater fish consumption on the status of long-chain n-3 fatty acids (n-3 LCPUFA) in infants in landlocked, low-income populations is unknown. We used secondary data from a randomized, single-blinded, controlled trial to evaluate the impact of daily consumption of complementary food products with small amounts of freshwater fish on whole blood n-3 LCPUFA in Cambodian infants. Infants (n = 419), received daily, one of four food products for 9 months.

Development and Acceptability of Locally Made Fish-Based, Ready-to-Use Products for the Prevention and Treatment of Malnutrition in Cambodia.

Background: Cambodia has a high prevalence of moderate acute malnutrition and severe acute malnutrition (SAM). The SAM treatment requires ready-to-use therapeutic foods (RUTFs), whereas ready-to-use supplementary foods (RUSFs) are used for prevention of acute malnutrition. Three locally produced fish-based products were developed: an RUTF paste (NumTrey-Paste) for treatment and 2 wafer versions, one for prevention (NumTrey-RUSF) and one for treatment (NumTrey-RUTF).

Identification of Acute Malnutrition in Children in Cambodia Requires Both Mid Upper Arm Circumference and Weight-For-Height to Offset Gender Bias of Each Indicator.

Malnutrition remains a serious health problem in Cambodia with over 10% of children less than five years of age suffering from acute malnutrition. In addition to the presence of nutritional edema, two indicators are recommended by the World Health Organization for the diagnosis of acute malnutrition: weight-for-height Z-scores (WHZ; with acute malnutrition defined as WHZ < −2 Z-score) and mid-upper arm circumference (MUAC, with acute malnutrition defined as MUAC < 12.5 cm).

Effect of multi-micronutrient-fortified rice on cognitive performance depends on premix composition and cognitive function tested: results of an effectiveness study in Cambodian schoolchildren.

Objective: Even though current policy is strongly focused on the crucial first '1000 days', it might be still possible to enhance cognitive function during the pre-adolescent and adolescent years by improving micronutrient status. In Cambodia, nutritional status is poor. Provision of rice fortified with micronutrients through a school meal programme (SMP) could be a cost-effective strategy to help improve health and school performance.

High prevalence of thiamine (vitamin B1) deficiency in early childhood among a nationally representative sample of Cambodian women of childbearing age and their children.

Background: Thiamine deficiency is thought to be an issue in Cambodia and throughout Southeast Asia due to frequent clinical reports of infantile beriberi. However the extent of this public health issue is currently unknown due to a lack of population-representative data. Therefore we assessed the thiamine status (measured as erythrocyte thiamine diphosphate concentrations; eThDP) among a representative sample of Cambodian women of childbearing age (15-49 y) and their young children (6-69 mo).

The High Prevalence of Anemia in Cambodian Children and Women Cannot Be Satisfactorily Explained by Nutritional Deficiencies or Hemoglobin Disorders.

Background: Anemia is highly prevalent in Cambodian women and children, but data on causes of anemia are scarce. We performed a national micronutrient survey in children and women that was linked to the Cambodian Demographic Health Survey 2014 (CDHS-2014) to assess the prevalence of micronutrient deficiency, hemoglobin disorders and intestinal parasite infection.

Methods: One-sixth of households from the CDHS-2014 were selected for a follow-up visit for the micronutrient survey.

Species-Specific Associations Between Soil-Transmitted Helminths and Micronutrients in Vietnamese Schoolchildren.

Soil-transmitted helminth (STH) infections and micronutrient deficiencies are closely related and often coexist among low-income populations. We studied the association between infections with specific STH species and micronutrient status in rural Vietnamese schoolchildren. Children (N = 510) aged 6-9 years were recruited from two primary schools.

Low Prevalence of Iron and Vitamin A Deficiency among Cambodian Women of Reproductive Age.

Nearly half of women of reproductive age (WRA) in Cambodia are anemic. To guide interventions, national data on nutritional causes of anemia, including iron deficiency and vitamin A deficiency, are needed. In 2012, a national household survey in WRA on antibodies to routine vaccine-preventable disease immunity was performed.

Impact of Multi-Micronutrient Fortified Rice on Hemoglobin, Iron and Vitamin A Status of Cambodian Schoolchildren: a Double-Blind Cluster-Randomized Controlled Trial.

In Cambodia, micronutrient deficiencies remain a critical public health problem. Our objective was to evaluate the impact of multi-micronutrient fortified rice (MMFR) formulations, distributed through a World Food Program school-meals program (WFP-SMP), on the hemoglobin concentrations and iron and vitamin A (VA) status of Cambodian schoolchildren. The FORISCA-UltraRice+NutriRice study was a double-blind, cluster-randomized, placebo-controlled trial.

Micronutrient-Fortified Rice Can Increase Hookworm Infection Risk: A Cluster Randomized Trial.

Background: Fortification of staple foods is considered an effective and safe strategy to combat micronutrient deficiencies, thereby improving health. While improving micronutrient status might be expected to have positive effects on immunity, some studies have reported increases in infections or inflammation after iron supplementation.

Objective: To study effects of micronutrient-fortified rice on hookworm infection in Cambodian schoolchildren.

Determination of zinc status in humans: which indicator should we use?

Zinc deficiency has serious wide-ranging health consequences and is thought to be one of the most prevalent micronutrient deficiencies in the world. However, reliable indicators or biomarkers to assess zinc status are not available at present. Indirect indicators such as the prevalence of stunting or anemia, iron deficiency, as well as more direct indicators such as plasma zinc concentrations are being used at present to estimate the prevalence of zinc deficiency in populations.

Effects of animal source food and micronutrient fortification in complementary food products on body composition, iron status, and linear growth: a randomized trial in Cambodia.

Background: Poor nutritional quality of complementary foods often limits growth. Animal source foods, such as milk or meat, are often unaffordable. Local affordable alternatives are needed.

Organoleptic qualities and acceptability of fortified rice in two Southeast Asian countries.

Fortified rice has the potential to improve the micronutrients status of vulnerable populations. However, fortified rice has to have acceptable organoleptic--the sensory properties of a particular food--qualities. Few data exist on the acceptability of fortified rice in Asia.

Optimal screening of children with acute malnutrition requires a change in current WHO guidelines as MUAC and WHZ identify different patient groups.

Background: Timely treatment of acute malnutrition in children <5 years of age could prevent >500,000 deaths annually. Screening at community level is essential to identify children with malnutrition. Current WHO guidelines for community screening for malnutrition recommend a Mid Upper Arm Circumference (MUAC) of <115 mm to identify severe acute malnutrition (SAM).

The use of linear programming to determine whether a formulated complementary food product can ensure adequate nutrients for 6- to 11-month-old Cambodian infants.

Background: A new software tool, Optifood, developed by the WHO and based on linear programming (LP) analysis, has been developed to formulate food-based recommendations.

Objective: This study discusses the use of Optifood for predicting whether formulated complementary food (CF) products can ensure dietary adequacy for target populations in Cambodia.

Design: Dietary data were collected by 24-h recall in a cross-sectional survey of 6- to 11-mo-old infants (n = 78).

Legal framework for food fortification: examples from Vietnam and Indonesia.

Background: Food fortification is a cost-effective, powerful, and sustainable strategy to combat micronutrient deficiency, with the potential to reach large sections of the population with minimal cost and effort. However, the implementation of food fortification on a systematic and large scale, for instance in national programs, has often been challenging.

Objective: This paper takes a closer look at food fortification efforts and legislation mechanisms in Vietnam and Indonesia in order to determine specific factors and components in the legal framework that are crucial to the success of fortification programs.

A six-month intervention with two different types of micronutrient-fortified complementary foods had distinct short- and long-term effects on linear and ponderal growth of Vietnamese infants.

Traditional complementary foods (CF) with a low nutrient density have been implicated in growth faltering, stunting, and other adverse outcomes in children. The efficacy of 2 types of locally produced, micronutrient-fortified CF to prevent stunting of infants living in rural Vietnam was evaluated. In a village-randomized controlled study, 426 infants, 5 mo of age, received for 6 mo a fortified CF, either as an instant flour (FF) or a food complement (FC) in village canteens, or traditional CF at home (C).
