Factors associated with anaemia in a nationally representative sample of nonpregnant women of reproductive age in Nepal
We used cross-sectional data from the 2016 Nepal National Micronutrient Status Survey to evaluate factors associated with anaemia among a nationally representative sample of nonpregnant women 15- 49 years (n = 1, 918). Haemoglobin, biomarkers of iron status and other micronutrients, infection, inflammation, and blood disorders were assessed from venous blood. Soil-transmitted helminth and Helicobacter pylori infections were assessed from stool. S…
Factors associated with anaemia among adolescent boys and girls 10–19 years old in Nepal
We used data from the 2016 Nepal National Micronutrient Status Survey to evaluate factors associated with anaemia (World Health Organization cut-points using altitude- and smoking-adjusted haemoglobin [Hb]) among nationally representative samples of adolescents 10-19 years. Hb, biomarkers of micronutrients, infection and inflammation were assessed from venous blood. Sociodemographic and household characteristics, dietary diversity, pica and recen…
Predictors of micronutrient powder sachet coverage and recent intake among children 12–23 months in Eastern Uganda
We evaluated predictors of micronutrient powder (MNP) sachet coverage and recent intake using data from a cross-sectional survey representative of children aged 12-23 months in Amuria district, Uganda. In June/July 2016, caregivers were interviewed 12 months after implementation of an integrated MNP and infant and young child feeding pilot (N = 761). Logistic regression described predictors of (a) high-MNP sachet coverage (received at least 60 sa…
Predictors of micronutrient powder ( MNP ) knowledge, coverage, and consumption during the scale‐up of an integrated infant and young child feeding ( Iycf‐MNP ) programme in N epal
Large-scale programmes using micronutrient powders (MNPs) may not achieve maximum impact due to limited/inappropriate MNP coverage, consumption, and use. We identify predictors of MNP coverage, maternal knowledge of appropriate use, and child MNP consumption in Nepal. A cross-sectional survey was conducted in 2,578 mother-child pairs representative of children 6-23 months in two districts that were part of the post-pilot, scale-up of an integrate…
An integrated infant and young child feeding and small‐quantity lipid‐based nutrient supplementation programme in the Democratic Republic of Congo is associated with improvements in breastfeeding and …
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 of integrated IYCF-SQ-LNS programmes on IYCF practices. A 2-year, enhanced IYCF intervention targeting pregnant women and infants (0-12 months) was implemented in a health zone in the Democra…
Changes in growth, anaemia, and iron deficiency among children aged 6–23 months in two districts in Nepal that were part of the post‐pilot scale‐up of an integrated infant and young child feeding and …
There is limited research on integrated infant and young child feeding (IYCF) and micronutrient powders (MNPs) programmes operating at scale, despite widespread implementation. This study uses cross-sectional baseline (n = 2,542) and endline (n = 2,578) surveys representative of children 6-23 months in two districts in Nepal that were part of a post-pilot scale-up of a IYCF-MNP programme. Multivariable log-binomial regression models were used to …
Urinary Concentrations of Dialkylphosphate Metabolites of Organophosphorus Pesticides
Organophosphorus (OP) insecticides were among the first pesticides that EPA reevaluated as part of the Food Quality Protection Act of 1996. Our goal was to assess exposure to OP insecticides in the U.S. general population over a six-year period. We analyzed 7,456 urine samples collected as part of three two-year cycles of the National Health and Nutrition Examination Survey (NHANES) from 1999-2004. We measured six dialkylphosphate metabolites of …
