Estimates of iron status in a random sample (218 men, 283 women) of the Northern Ireland population (aged 18-64 years) were obtained from blood measurements. Multiple criteria were used to determine Fe deficiency and body Fe stores were calculated as an index of Fe sufficiency. Three distinct groups with respect to Fe stores were identified on the basis of sex and menstrual status. Estimates of body Fe stores, mean (and SD), were 13.4 (SD 5.97), 5.3 (SD 6.09) and 8.5 (SD 6.72) mM for men, woman aged 18-44 years and women aged 45-64 years respectively. The prevalence of Fe-deficiency anaemia was low, ranging from 0.5% in men to 6.6% and 4.6% in the younger and older women respectively. The prevalence of Fe deficiency was low in men (1.4%) and older women (5.7%) rising to 11.0% in the younger group of women. The disproportionately elevated serum ferritin relative to transferrin saturation supported the suggestion that chronic inflammation might have influenced Fe status measurements in men and older women.

:从血液测量中获得北爱尔兰人口(18-64岁)的随机样本(218例男性,283例女性)中铁的状况估计值。使用多个标准来确定铁缺乏症,并计算体内铁存储量作为铁充足性的指标。根据性别和月经状况,确定了关于铁存储的三个不同的类别。男性,18-44岁的女性和45-64岁的女性的体内铁存储量的平均值(和SD)分别为13.4(SD 5.97),5.3(SD 6.09)和8.5(SD 6.72)mM。缺铁性贫血的患病率很低,从男性的0.5%到年轻女性和老年女性的6.6%和4.6%。男性中铁缺乏症的患病率较低(1.4%),老年妇女中铁缺乏症的患病率(5.7%)上升至11.0%。相对于转铁蛋白饱和度而言,血清铁蛋白的升高不成比例地支持了这样的建议,即慢性炎症可能已经影响了男性和老年女性的铁状态测量。
