“…Of the total number of participants, only 9.6% were male. Two studies [ 70 , 71 ] included exclusively all-male populations, compared with 29 studies [ 14 , 29 , 30 , 31 , 32 , 33 , 34 , 36 , 37 , 42 , 45 , 46 , 48 , 50 , 51 , 52 , 53 , 54 , 56 , 58 , 60 , 61 , 62 , 64 , 67 , 68 , 73 , 74 , 75 ] that included exclusively females.

“…The age of participants across all included studies ranged from 18 to 93 years.

Is Higher Consumption of Animal Flesh Foods Associated with Better Iron Status among Adults in Developed Countries? A Systematic Review

et al. 2016

Iron deficiency (ID) is the most prevalent nutrient deficiency within the developed world. This is of concern as ID has been shown to affect immunity, thermoregulation, work performance and cognition. Animal flesh foods provide the richest and most bioavailable source of dietary (haem) iron, however, it is unclear whether low animal flesh diets contribute to ID. This systematic review aimed to investigate whether a higher consumption of animal flesh foods is associated with better iron status in adults. CINAHL, Cochrane, EMBASE and MEDLINE were searched for published studies that included adults (≥18 years) from developed countries and measured flesh intakes in relation to iron status indices. Eight experimental and 41 observational studies met the inclusion criteria. Generally, studies varied in population and study designs and results were conflicting. Of the seven high quality studies, five showed a positive association between animal flesh intake (85–300 g/day) and iron status. However, the optimum quantity or frequency of flesh intake required to maintain or achieve a healthy iron status remains unclear. Results show a promising relationship between animal flesh intake and iron status, however, additional longitudinal and experimental studies are required to confirm this relationship and determine optimal intakes to reduce ID development.

AbstractIron deficiency (ID) is a major public health problem worldwide among children aged 0–12 months. Several factors seem to contribute to the iron-deficient state in infancy, including insufficient antenatal and neonatal iron supplementation, exclusive breastfeeding, and early umbilical cord clamping after birth. The most concerning complications of ID, except for anemia, are related to altered long-term neurodevelopment. Clinical studies have shown a negative impact of ID anemia on fetal and neonatal behavior including impairments of motor maturity, autonomic response, memory/learning, and mood. ID-induced defects during infancy seem to persist later in life, even after ID treatment. The underlying mechanisms involve dysfunctional myelination, neurotransmission alterations, and altered synaptogenesis and/or dendritogenesis. The purpose of the present review is to summarize these mechanisms and to provide recommendations for future clinical research in the field.

“…Teen blood donors are sometimes even warned by blood collectors in predonation educational materials to be careful about timing their blood donation so that it does not interfere with major tests or athletic events. This concern may be especially warranted in young women, as there is evidence that low iron is related to deficits in cognitive functioning [40,41,46]. For example, Blanton et al [41] recently found in healthy college-aged women that low iron status, in the absence of iron-deficiency anaemia, was related to a significant slowing of planning speed in a test of central executive function.…”

Young donor health and safety: are we doing enough?

In some countries, blood collection is permitted from donors as young as 16 years of age. Young donors represent a unique challenge for blood collection organizations as they must balance their need for these donors against protecting the health and safety of this potentially vulnerable donor population. As young donors have become increasingly important to ensuring the adequacy of the blood supply, donor haemovigilance programmes found that they were disproportionally affected by adverse blood donation reactions. These findings served as the impetus for many blood collection organizations to implement interventions to reduce donor reaction rates in the younger age groups. While blood collectors have made great strides in reducing the rates of immediate adverse reactions of blood donation, less attention has been paid to possible long-term consequences of iron deficiency. With increased reliance on young donors to provide a significant part of the blood supply, it is of the utmost importance that these donors have a good experience when they donate blood and do not suffer any adverse health and safety effects from their altruistic act. Adverse donor reactions and iron deficiency still pose threats to the health and safety of young donors. Continued research is needed in both of these areas to adequately protect young donors.
