Proper nutrition is a cornerstone of good health. Basic rules to follow for proper nutrition : From http://www.safefood.eu/Healthy-Eating/What-is-a-balanced-diet/The-FoodPyramid.aspx - to pay attention to individual foods or nutrients of food; - to ensure that intake is proportionate to the caloric energy expenditure; - to ensure a varied and balanced diet. Nutrition not only serves to replace energy reserves but also to feed most of the strategic regulatory systems of the organism (e.g. the nervous, immune, endocrine system …) From Ministero della salute. “Guadagnare salute” - Rendere facili le scelte salutari. http://www.salute.gov.it/imgs/C_17_pubblicazioni_605_allegato.pdf NUTRITION AND BLOOD DONATION: WHICH LINK?

Valutazione delle condizioni generali di salute del donatore 1. Mira ad evidenziare le condizioni generali di salute del candidato donatore con particolare attenzione a stati quali debilitazione, iponutrizione, edemi, anemia, ittero, cianosi, dispnea, instabilita' mentale, intossicazione alcolica, uso di stupefacenti ed abuso di farmaci. For the protection of donors’ health Allegato 7 C) Esami per il donatore periodico. Il donatore periodico, oltre agli esami indicati ai precedenti punti A e B, ogni anno e' sottoposto ai seguenti esami: creatininemia; glicemia; proteinemia ed elettroforesi sieroproteica colesterolemia; trigliceridemia; ferritinemia. BODY MASS INDEX (BMI) AND OBESITY A moderately high prevalence of obesity among healthy blood donors has been reported in some studies, with demographic associations comparable to those seen in population-based studies. STUDY Edward L Murphy, Karen Schlumpf, David J Wright, Ritchard Cable,Ronald Sacher, and Michael P Busch for the NHLBI Retrovirus Epidemiology Donor Study II. BMI and obesity in US blood donors: a potential public health role for the blood centre Public Health Nutr2012 June ; 15(6): 964–971. KEY POINT We found a moderately high prevalence of obesity among otherwise healthy US blood donors, with demographic associations comparable to those seen in population-based studies. As some blood centres move towards measurement of cholesterol and glycosylated Hb as a service to donors, the combination of these indices with BMI could lead to useful health education measures and even interventions to induce health-conscious blood donors to maintain healthier diet and lifestyles.

CARDIOVASCULAR RISK FACTORS (CVR) (I) Although blood donation targets healthy individuals, data suggest that a relevant percentage of blood donors could have at least one cardiovascular risk factor, some at critical levels as defined by National Heart, Lung, and Blood Institute (NHLBI): High blood pressure High blood cholesterol Diabetes and prediabetes Smoking Being overweight or obese Being physically inactive Having a family history of early heart disease Having a history of preeclampsia during pregnancy Unhealthy diet Age National Heart, Lung, and Blood Institute (NHLBI).

In this study 61% of the health screening participants reported being motivated to very motivated to change their lifestyle behaviors including diet, exercise, and/or smoking.

VITAMIN DEFICIENCY Although the finding of vitamin deficiency in blood donors in developed countries is an infrequent event, some studies showed that this group of apparently healthy adults may be at risk for nutritional deficiency.

AIS (Absent Iron Stores) Plasma ferritin < 12 ng/mL This cutoff is a highly specific indicator of iron deficiency that reflects absent tissue and marrow iron store, but lacks sensitivity IDE (Iron Deficient Erythropoiesis) Identified by Log of the ratio: soluble Transferrin Receptor / Ferritin. The use of the two reciprocally regulated measurements seems to provide excellent discrimination of clinical iron deficiency anemia and experience in blood donors suggests high sensitivity in the detection of iron-deficient erytrhopoiesis (IDE) IRON DEFICIENCY AIS: absent iron stores IDE: iron deficient erythropoiesis 1. Deferral for low Hb is the most common cause of presenting donor loss [RISE study: 9.9% of all donation attempts (17.7% females, 1.6% males) end in a deferral for low Hb or Ht] 2. Based on currently accepted Hb reference ranges for all adults*, some female donors with values within the reference range are deferred, and some male donors who are below the reference range are eligible to donate 3. An analysis of NHANES II** data for adults shown to have adequate iron stores also shows that 12.5 g/dL is not an appropriate lower limit for blood donation to prevent iron depletion […] 4. In most cases there are “non protective” changes in donor Hb in frequent donors as a function of prior donation intensity **) *) 5. The Hb screen is a poor assessment of the iron status of blood donors ** 6. Previous donation intensity and gender are the most important predictors of iron deficiency and iron deficient erythropoiesis (IDE) 7. Other independent predictors : age, weight, smoking, iron supplementation, HFE genotype, menstrual and pregnancy status 8. Optimizing the safety of blood donation for volunteer donors requires significant attention and specific committment 9. To what extent the current donor standards can prevent and detect significant adverse donor sequelae related to iron depletion? **) **) Hemoglobin & Ferritin general data from 6 Italian Regions 86,518 blood donors 86% repeat donors (median age 42) 14% first-time donors (median age 34) 19,833 female 66,685 male Hb (g/dL) Ferritin (ng/mL) Female donors: 13.3 Male donors: 15.1 FT donors: All 14.5 F 13.4 M 15.3 RR donors: All 14.8 F 13.3 M 15.2 Reference range: Min 15-20 / Max 260-300 FT donors: > lower limit: 82% < lower limit: 15% > upper limit: 3% RR donors: > lower limit: 80%; < lower limit: 19.5%; > upper limit: 0.5% p < 0.05 Hemoglobin & Ferritin data from 2 Italian Regional Blood Centres 24,535 blood donors RBC 1: 54% / RBC 2: 46% 7,360 FT donors (30%) - median age 40 17,175 RR donors (70%) - median age 46 29% female 71% male 113,040 WB/RBC donations Average WB/RBC donation frequency: Male 1.3/year Female 1.1/year Hb (g/dL) Ferritin (ng/mL) FT donors: F 13.8 M 15.3 RR donors: F 13.7 M 15.1 Female donors: 33 Male donors: 86 FT donors: F 34 M 95 RR donors: F 29 M 46 Reg.
