The Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) research group was formed over a decade ago to improve the interpretation micronutrient biomarkers in settings with inflammation. BRINDA inflammation adjustment method uses regression correction adjust for confounding effects on select has provided important insights research, policy, programming. However, users may face challenges when applying methods their own data due varying guidance approach...
In Vietnam, nutrition interventions do not target school children despite a high prevalence of micronutrient deficiencies. The present randomised, placebo-controlled study evaluated the impact providing ( n 403) with daily multiple micronutrient-fortified biscuits (FB) or weekly Fe supplement (SUP) on anaemia and deficiency. Micronutrient status was assessed by concentrations Hb, plasma ferritin (PF), transferrin receptor (TfR), Zn retinol. After 6 months intervention, receiving FB SUP had...
Abstract Vitamin A deficiency (VAD) is an important contributor to child morbidity and mortality. The prevalence of VAD, measured by retinol‐binding protein (RBP) or retinol, overestimated in populations with a high inflammation. We aimed quantify adjust for the effect inflammation on VAD nationally representative survey Liberian children 6 35 months age. compared five approaches RBP estimate (defined as < 0.7 µmol/L): (1) ignoring inflammation; (2) excluding individuals (C‐reactive (CRP)...
Abstract Inflammation and infections such as malaria affect concentrations of many micronutrient biomarkers, hence estimates nutritional status. We aimed to assess the relationship between infection biomarker in pre-school children (PSC), school-age (SAC) women reproductive age (WRA) Malawi, examine potential role immunity on biomarkers. Data from 2015/2016 Malawi survey were used. The associations current or recent infection, detected by rapid diagnostic test, concentration serum ferritin,...
Folate is essential for the synthesis and integrity of DNA, normal cell formation, body growth. deficiency among women reproductive age (WRA) increases risk poor birth outcomes including neural tube defect (NTD)-affected pregnancies. status largely dependent on dietary intakes.
Objectives Vitamin A deficiency affects an estimated 29% of all children under 5 years age in low/middle-income countries, contributing to child mortality and exacerbating severity infections. Biannual vitamin supplementation (VAS) for aged 6–59 months can be a low-cost intervention meet needs. This study aimed present framework evaluating the equity dimensions national VAS programmes according determinants known affect nutrition assist programming by highlighting geographical variation...
Small-quantity lipid-based nutrient supplements (SQ-LNS) are efficacious in controlled settings; data scarce on the effectiveness utilizing health care delivery platforms.We evaluated impact of an infant young child feeding (IYCF)-SQ-LNS intervention anemia and growth children aged 6-18 mo Democratic Republic Congo following a quasi-experimental design.An zone (HZ) received enhanced IYCF including improved counseling during pregnancy until 12 after birth daily use SQ-LNS for infants 6-12 mo;...
Integrating small-quantity lipid-based nutrient supplements (SQ-LNS) into infant and young child feeding (IYCF) programmes can increase consumption of essential nutrients among children in vulnerable populations; however, few studies have assessed the impact integrated IYCF-SQ-LNS on IYCF practices. A 2-year, enhanced intervention targeting pregnant women infants (0-12 months) was implemented a health zone Democratic Republic Congo (DRC). The included community- facility-based counselling...
Retinol Binding Protein (RBP) is responsible for the transport of serum retinol (SR) to target tissue in body. Since RBP relatively easy and cheap measure, it widely used national Micronutrient Surveys (MNS) as a proxy SR determine vitamin A status. By regressing concentration against measured subset survey population, one can define population-specific threshold that indicates deficiency (VAD). However, relationship between concentrations affected by various factors including inflammation....
Objectives: To determine a culturally appropriate product name and package design that would communicate important usage instructions for lipid-based nutrient supplement (LNS) target population with diverse languages low literacy.
 Methods: Formative work was conducted in two locations Katanga region, DRC: Mabaya, rural village Kipushi, peri-urban area. In each site, focus group discussions parents of children aged 0-24 months (3 mothers, 1 fathers) were conducted. Additionally, key...
Background: Because micronutrient deficiencies affect public health, countries monitor population status by national-scale, multi-stage, surveys (MNS). In design-based surveys, inclusion probabilities are specified for sample units and the corresponding weights allow design-unbiased estimates to be made of parameters. Corrections may possible on departures from design; an alternative is use linear mixed models (LMM), with estimated covariance structure reflecting sampling design, obtain...
Abstract Inflammation and infections such as malaria affect micronutrient biomarker concentrations hence estimates of nutritional status. It is unknown whether correction for C-reactive protein (CRP) α 1-acid glycoprotein (AGP) fully captures the modification in ferritin during a infection, or environmental sociodemographic factors modify this association. Cross-sectional data from eight surveys children aged 6–59 months (Cameroon, Cote d’Ivoire, Kenya, Liberia, Malawi, Nigeria Zambia; n...
Vitamin A deficiency (VAD) is an important contributor to child morbidity and mortality. The prevalence of VAD, measured by retinol binding protein (RBP) retinol, overestimated in populations with a high inflammation. We aimed quantify adjust for the effect inflammation on VAD nationally representative survey Liberian children 6 35 months age. compared four methods RBP estimate prevalence: 1) ignoring inflammation, 2) excluding individuals (elevated C‐reactive (CRP) or alpha1‐acid...
Objectives: To address the high prevalence of anemia and chronic malnutrition (71% 43% among children <5 respectively), UNICEF CDC supported Ministry Public Health to develop an integrated IYCN pilot program in October 2012, which includes distribution a small-quantity, lipid-based nutrition supplement (SQ-LNS), through routine health system. The targets 16,500 0-12 months their mothers. Methods: involves i) monthly individual group counseling by trained workers volunteers, ii) SQ-LNS...
