The objective of the study is to assess the acceptability, feasibility, and barriers to Lucky Iron Fish™ (LIF) utilization among families with young children in a Latin American community with a high prevalence of iron deficiency and iron-deficiency anemia. .
The primary objective is to assess the acceptability of cooking with an iron ingot (Lucky Iron Fish™) compared to traditional oral iron supplementation methods among preschool aged children in a Dominican community with a high prevalence of anemia (\> 50%). Data will be collected to characterize the natural history of iron deficiency and anemia in pre-school aged children in a Dominican community. The study will involve a randomized control trial to assess the primary objective: children \> 1 year and \< 5 years of age will be randomized into two study arms: LIF plus citrus (LIF arm) versus standard iron-supplementation (enhanced standard of care). Participants enrolled in the both study arms will have study labs drawn every 3, 6, and 12-months (hemoglobin, serum ferritin, c-reactive protein) to assess the natural history of iron deficiency in these children. Concomitant to study labs, parents/guardians will be surveyed on acceptability, compliance, and barriers to use of their assigned iron supplementation method. Primary study outcomes are the change in hemoglobin within the LIF group and then difference in change in hemoglobin between study arms over a 12-month study period. Secondary outcomes include changes in serum ferritin within and between study arms and exploring the relationship between changes in hemoglobin, serum ferritin, and C-reactive protein

Enrollment
80
200g iron ingot that is placed in boiling water for 10+ minutes, and then removed. The water is then used to eating and drinking.
parents of subjects are provided oral iron supplementation per usual clinical care at clinic and followed for their anemia in addition to study visits

Rates of refusal
Rates of refusal to participate in study measured as proportion of subjects refusing to enter study compared to total number approached.
Time frame: 12-months
Retention
Within each study arm (Iron ingot vs. Oral iron supplementation), will calculate proportion lost to follow-up. Number of subjects lost to follow up divided total number of subjects enrolled at study entry.
Time frame: 12-months
Adherence to iron ingot use
Using a questionnaire with several likert-scale questions, we will assess adherence to iron ingot use. Questions include "When was the last time you used the Fish", "how often do you use the fish for meal preparation", "how often do you use the fish to prepare water", "how long do you typically boil the fish". The answer to each question has between 4-5 possible ordinal responses which will be converted into numerical data (1,2,3,4,5) and cumulative scores will be created to assess degree of use/adherence.
Time frame: 12-months
Adherence to oral iron use
Using a questionnaire with several likert-scale questions, we will assess adherence to oral iron supplementation. Questions include: "How many doses were missed each week", "Do you recall dose and frequency of oral iron you were prescribed", "If doses were missed, was this accidental, intentional, or both". The answer to each question has between 4-5 possible ordinal responses which will be converted into numerical data (1,2,3,4,5) and cumulative scores will be created to assess degree of use/adherence.
Time frame: 12-months
Natural history of hemoglobin among those subjects using iron ingot
We will assess changes in hemoglobin WITHIN iron ingot study arm. Hemoglobin will be measured in grams per deciliter (g/dL) and measured at enrollment, 3-months, 6-months, and 12-months. If data is normally distributed, a paired/dependent t-test will be used, if non-normal, a non-parametric test like Wilcoxon's Matched pairs test will be used.

Time frame: Will be at 4 individual points over a 12-mo period - at enrollment, 3-month follow-up, 6-month follow-up, and 12-month follow-up which is study end. Thus, the time frame is 4 separate visits over a 12-month period

Natural history hemoglobin: Iron ingot vs. Oral iron
The difference in change in hemoglobin (measure in g/dL) between the study study arms (iron ingot arm vs. oral iron supplementation arm) will be assessed using two-sample t-test (normal distribution) or Wilcoxon-rank-sum (non-normal distribution).
Time frame: 12-month.
Natural history of serum ferritin among subjects using iron ingot
We will assess changes in serum ferritin WITHIN iron ingot study arm. Serum ferritin will be measured in nanograms per milliliter (ng/mL) and measured at enrollment, 3-months, 6-months, and 12-months. If data is normally distributed, a paired/dependent t-test will be used, if non-normal, a non-parametric test like Wilcoxon's Matched pairs test will be used.
