December 2016 – IDD Newsletter

Over the past decade, Angola has made continuous efforts to enhance its salt iodization program. Salt iodization was made mandatory in 2008, and according to the existing survey and monitoring data, the majority of salt in Angola is iodized (although the adequacy of iodized salt is unknown). Despite these advances, there has not been a comprehensive and recent assessment of iodine status in children and women nor of the iodine content of table salt at the production sites or in the households. To address this information gap, a situation analysis of Angola’s salt iodization program was conducted in July 2016, and provides detailed recommendations to enhance the program moving forward. This situation analysis was followed by a workshop of salt producers and public health stakeholders in September 2016, and advocacy activities promoting the benefits of iodized salt were conducted in October 2016.

Oman National Nutrition Survey

Project Completed

 
GroundWork is providing technical support to the Ministry of Health and UNICEF to plan and implement a national nutrition survey in Oman. GroundWork’s support includes the development of a scientific survey protocol, procurement of blood collection materials, training of survey field staff, supervision of data collection, coordination of biomarker assessment, data analysis and drafting of the survey report.

Investigating the association between enteropathy and stunting in young children in Tanzania

Project Completed

 
In collaboration the International Food Policy Research Institute (IFPRI), Helen Keller International (HKI), and the World Health Organization (WHO), Tanzania’s National Institute for Medical Research (NIMR) and GroundWork have conducted a case-control study to investigate the associations between stunting and biomarkers of environmental enteropathy in young children in Tanzania’s Lake Zone. Along with questionnaire data collected as part of an endline study implemented by IFPRI, HKI, and NIMR, enteropathy biomarkers were measured in blood and stool samples collected from children 22-28 months of age. As part of this project, GroundWork developed the scientific protocol, procured stool collection and laboratory analysis materials, trained survey field staff, and conducted laboratory analysis.

Adequate supply of micronutrients during the first 1000 days is essential for normal development and healthy life. To investigate if interventions administering dietary doses of iron and zinc from conception to age 2 years have the potential to influence nutritional status and development of children, we conducted a systematic review and meta-analysis of randomized and quasi-randomized fortification, biofortification, and supplementation trials in women (pregnant and lactating) and children (6–23 months) delivering iron or zinc in doses up to the recommended nutrient intake (RNI) levels. Supplying iron or zinc during pregnancy had no effects on birth outcomes. There were limited or no data on the effects of iron/zinc during pregnancy and lactation on child iron/zinc status, growth, morbidity, and psychomotor and mental development. Delivering up to 15 mg iron/day during infancy increased mean hemoglobin by 4 g/L (p < 0.001) and mean serum ferritin concentration by 17.6 µg/L (p < 0.001) and reduced the risk for anemia by 41% (p < 0.001), iron deficiency by 78% (ID; p < 0.001) and iron deficiency anemia by 80% (IDA; p < 0.001), but had no effect on growth or psychomotor development. Providing up to 10 mg of additional zinc during infancy increased plasma zinc concentration by 2.03 µmol/L (p < 0.001) and reduced the risk of zinc deficiency by 47% (p < 0.001). Further, we observed positive effects on child weight for age z-score (WAZ) (p < 0.05), weight for height z-score (WHZ) (p < 0.05), but not on height for age z-score (HAZ) or the risk for stunting, wasting, and underweight.
