NCT ID: NCT06391437 Completed - Clinical trials for Vitamin A Deficiency in Children

Prevalence Of Vitamin A Deficiency In Critically Ill Children With Sepsis And Its Association With Clinical Outcomes

Start date: May 1, 2023
Phase:
Study type: Observational

Aim of the work is to assess the prevalence of vitamin A deficiency in critically ill children with sepsis and the association between vitamin A deficiency and clinical outcomes

NCT ID: NCT05893901 Completed - Iron-deficiency Clinical Trials

Impact of Food-to-Food Fortified Cereal Products on Diet Quality in Rural Niger Villages

NigerMPS
Start date: March 13, 2023
Phase:
Study type: Observational [Patient Registry]

The primary hypothesis is that introduction of food-to-food fortified products through a rural Hub-and-Spoke incubator system contributes to an improved food environment and availability of micronutrients to these communities. A secondary hypothesis is that the influence of the rural Spokes can serve to enhance rural food environments through creation of secondary rural spokes that disseminate improved food-to-food fortified products. The overall hypothesis is that a product designed with optimized nutritional characteristics, based on consumer preferences and leveraging local nutrient dense ingredients, can successfully deliver nutrition through sustainable market-driven approaches.

NCT ID: NCT05882682 Completed - Iron-deficiency Clinical Trials

Impact of Food-to-Food Fortified Cereal Products on Diet Quality in Eldoret, Kenya

KenyaMPS
Start date: October 20, 2022
Phase:
Study type: Observational [Patient Registry]

The overall hypotheses is that a product designed with optimized nutritional characteristics, based on consumer preferences and leveraging local nutrient dense ingredients, can successfully deliver nutrition through sustainable market-driven approaches. The objectives of this study will be 1) to assess the nutritional adequacy of Kenyan households with children and 2) to determine the market potential of a locally sourced and manufactured, blended fortified, cereal-based product for the improvement of micronutrient deficiencies among children aged 24-60 months. This study will simulate a market study, the investigators conducted a product launch, determined market potential based on sales, evaluated marketing strategy to increase market share, and modeled the nutritional contribution of FtFF/traditionally fortified product for iron, zinc, and vitamin A. The investigators expect to provide a throughout evaluation of a business-driven strategy (for profit, social enterprise) as a sustainable tool to decrease micronutrient deficiencies.

NCT ID: NCT05872061 Completed - Iron-deficiency Clinical Trials

Senegal Market Study for Food-to-Food Fortified (F2F) Instant Porridge Flours

SenegalMPS
Start date: January 27, 2022
Phase:
Study type: Observational

The overall hypotheses is that a product designed with optimized nutritional characteristics, based on consumer preferences and leveraging local nutrient dense ingredients, can successfully deliver nutrition through sustainable market-driven approaches. The objectives of this study were 1) to assess the nutritional adequacy of urban Senegalese households with children and 2) to determine the market potential of a locally sourced and manufactured, blended fortified, cereal-based product for the improvement of micronutrient deficiencies among children aged 24-60 months. This study simulates a market study, the investigators will conduct a product launch, determine market potential based on sales, evaluate marketing strategy to increase market share, and model the nutritional contribution of FtFF/traditionally fortified product for iron, zinc, and vitamin A. The investigators expect to provide a thorough evaluation of a business-driven strategy (for profit, social enterprise) as a sustainable tool to decrease micronutrient deficiencies.

NCT ID: NCT04780958 Completed - Clinical trials for Vitamin A Deficiency

Retinol Status in Preterm Infants and Mothers

Start date: June 1, 2020
Phase: N/A
Study type: Interventional

Retinol and retinol binding protein were studied in the umbilical cord blood of 44 preterm infants with gestation age of < 30 weeks. Serum retinol and RBP levels were determined by enzyme-linked immunosorbent assay. The rate of transplacental retinol passage was calculated. The demographic data of mother and baby, vitamin use in the mother, antenatal steroid application and diseases diagnosed during pregnancy were recorded. An evaluation was made of the retinol, RBP and factors of the mother and baby affecting the transplacental retinol passage. The relationship between retinol and retinol binding protein levels and neonatal mortality and morbidity was investigated.

NCT ID: NCT04632771 Completed - Anemia Clinical Trials

Nutritional Status and Bouillon Use in Northern Ghana

Start date: October 19, 2020
Phase:
Study type: Observational

This pilot aims to generate data that are critical for informing the design of a planned, more detailed study to evaluate the effect of multiple micronutrient (MN)-fortified bouillon cube on biomarkers of nutrient status of women and children. Data collection includes measures of nutritional status and dietary intake among women and children and their households in communities in northern Ghana.

NCT ID: NCT04137354 Completed - Clinical trials for Anemia, Iron Deficiency

Iron and Vitamin A in School Children

IronVitA
Start date: November 2, 2020
Phase: N/A
Study type: Interventional

The WHO recommended intermittent iron supplementation as a strategy for prevention of anemia and iron deficiency among school age children. Several aspects of cognitive development, co-supplementation with other micronutrients, severe adverse events especially in the context of malaria were missing. The investigators will evaluate the effectiveness of intermittent iron and vitamin A supplementation on cognitive development and anemia and iron status of Rural Ethiopian school children.

NCT ID: NCT04123210 Completed - Clinical trials for Vitamin A Deficiency

Estimating Average Vitamin A Requirements in Indonesian and American Women

Start date: March 17, 2008
Phase: N/A
Study type: Interventional

Women of reproductive age had their vitamin A stores estimated by retinol isotope dilution and then were given vitamin A supplements near the US vitamin A RDA or placebo for 42(USA) or 60 (Indonesia) days, after which retinol isotope dilution was repeated and the change in vitamin A stores was determined in each group to estimate how much vitamin A is needed to maintain nutrient balance in these women.

NCT ID: NCT03640104 Completed - Clinical trials for Overweight and Obesity

Individualized Dietary Intervention in Breastfeeding Women: Body Weight and Vitamin A Stores

Start date: November 1, 2018
Phase: N/A
Study type: Interventional

Breast milk is the best food during the first 6mo of life because it offers multiple benefits for the mother-infant pair. An inadequate maternal diet during pregnancy can lead to excess weight gain, leading to negative health consequences for the dyad. In Mexico, an excess of body weight coexists with micronutrient deficiencies (double burden of malnutrition). Low vitamin A concentration has been observed in northwest Mexico, which can affect the human milk composition and increase the risk of VAD in breastfed babies. An individualized dietary intervention in the lactating woman will reduce body weight and improve vitamin A status. The objective is to assess the effect of an individualized dietary intervention during 3 months postpartum on body composition and vitamin A status of lactating women.

NCT ID: NCT03632876 Completed - Clinical trials for Sickle Cell Anemia in Children

Nutritional Outcomes After Vitamin A Supplementation in Subjects With SCD

Start date: October 2, 2015
Phase: N/A
Study type: Interventional

This study establishes the safety and efficacy of vit A supplementation doses (3000 and 6000 IU/d) over 8 weeks in children with SCD-SS, ages 9 and older and test the impact of vit A supplementation on key functional and clinical outcomes. Additionally, vitamin A status is assessed in healthy children ages 9 and older to compare to subjects with SCD-SS.
