Proposed Collection; Comment Request; REDS-II Donor Iron Status 
Evaluation (RISE) Study

SUMMARY: In compliance with the requirement of Section 3506(c)(2)(A) of 
the Paperwork Reduction Act of 1995, for opportunity for public comment 
on proposed data collection projects, the National Heart, Lung, and 
Blood Institute (NHLBI), the National Institutes of Health (NIH), will 
publish periodic summaries of proposed projects to the Office of 
Management and Budget (OMB) for review and approval.

Proposed Collection

    Title: REDS-II Donor Iron Status Evaluation (RISE) Study. Type of 
Information Collection Request: Revision of a currently approved 
collection. OMB control <greek-i> 0925-0581. Expiration Date: 05/31/
2009. Need and Use of Information Collection: Although the overall 
health significance of iron depletion in blood donors is uncertain, 
iron depletion leading to iron deficient erythropoiesis and lowered 
hemoglobin levels results in donor deferral and, occasionally, in mild 
iron deficiency anemia. Hemoglobin deferrals represent more than half 
of all donor deferral, deferring 16% of women. The RISE Study is a 
longitudinal study of iron status in two cohorts of blood donors: a 
first time/reactivated donor cohort in which baseline iron and 
hemoglobin status can be assessed without the influence of previous 
donations, and a frequent donor cohort, where the cumulative effect of 
additional frequent blood donations can be assessed. Each cohort's 
donors will donate blood and provide evaluation samples during the 
study period.
    The primary goal of the study is to evaluate the effects of blood 
donation intensity on iron and hemoglobin status and assess how these 
are modified as a function of baseline iron/hemoglobin measures, 
demographic factors, and reproductive and behavioral factors. 
Hemoglobin levels, a panel of iron protein, red cell and reticulocyte 
indices will be measured at baseline and at a final follow-up visit 15-
24 months after the baseline visit. A DNA sample will be obtained once 
at the baseline visit to assess three key iron protein polymorphisms. 
Donors will also complete a self-administered survey assessing past 
blood donation, smoking history, use of vitamin/mineral supplements, 
iron supplements, aspirin, frequency of heme rich food intake, and, for 
females, menstrual status and pregnancy history at these two time 
points. This study aims to identify the optimal laboratory measures 
that would predict the development of iron depletion, hemoglobin 
deferral, and/or iron deficient hemoglobin deferral in active whole 
blood and double red cell donors at subsequent blood donations. The 
data collected will help evaluate hemoglobin distributions in the blood 
donor population (eligible and deferred donors) and compare them with 
NHANES data. Other secondary objectives include elucidating key genetic 
influences on hemoglobin levels and iron status in a donor population 
as a function of donation history; and establishing a serum and DNA 
archive to evaluate the potential utility of future iron studies and 
genetic polymorphisms.
    This study will develop better predictive models for iron depletion 
and hemoglobin deferral (with or without iron deficiency) in blood 
donors; allow for the development of improved donor screening 
strategies and open the possibility for customized donation frequency 
guidelines for individuals or classes of donors; provide important 
baseline information for the design of targeted iron supplementation 
strategies in blood donors, and improved counseling messages to blood 
donors regarding diet or supplements; and by elucidating the effect of 
genetic iron protein polymorphisms on the development of iron 
depletion, enhance the understanding of the role of these proteins in 
states of iron stress, using frequent blood donation as a model.
    This request for modification is to add eleven questions to the 
RISE study final visit questionnaire that will include questions about 
Restless Leg Syndrome (RLS) and pica, two disorders associated with 
iron deficiency. RLS is a neurologic movement disorder in which 
patients complain of crawling, aching or indescribable feelings in 
their legs or just have the need to move. Pica is an eating disorder 
defined as compulsive ingestion of non-food substances. Blood donation 
results in the removal of 200-250 mg of iron from the donor. It is well 
established that repeated blood donation can produce iron deficiency, 
yet the prevalence of RLS and pica among blood donors is unknown. The 
REDS-II RISE study subjects are an ideal study population for the 
investigation of RLS and pica in blood donors. About 2,400 subjects 
with variable donation intensity (e.g. frequency with which a person 
donates blood) are currently enrolled in the RISE

[[Page 10058]]

Study. The iron status of all of these subjects is well characterized, 
including measurement of plasma ferritin and soluble transferrin 
receptor along with hemoglobin/hematocrit. These laboratory values 
allow each subject to be defined as (1) iron replete, (2) iron 
deficient without anemia or (3) iron deficiency anemia. The responses 
to these questions will be correlated with the laboratory test values 
to determine the relationship between blood donation and the 
development of RLS and pica and will establish its prevalence in these 
populations.
    Frequency of Response: Twice. Affected Public: Individuals. Type of 
Respondents: Adult blood donors. The annual reporting burden is a 
follows: Estimated Number of Respondents: Baseline visit: 2,340. Follow 
up Visit: 1,530; Estimated Number of Responses per Respondent: 1. 
Average Burden of Hours per Response: Baseline Visit: 0.37. Follow up 
Visit: 0.25; and Estimated Total Annual Burden Hours Requested: 
Baseline visit: 866. Follow up Visit: 383. The annualized cost to 
respondents is estimated at: Baseline Visit: $15,588, Follow up Visit: 
$6,894 (based on $18 per hour). There are no Capital Costs to report. 
There are no Operating or Maintenance Costs to report.
