The aim of the present study was to evaluate anemia, the biochemical status and dietary adequacy of iron (Fe), zinc (Zn) and copper (Cu), in Chilean childbearing age women. We studied a convenience sample of 86 women aged 18 to 48 years from Santiago, Chile. We determined anemia and the micronutrient status through hemoglobin (Hb) mean corpuscular volume, transferrin saturation, zinc protoporphyrin, serum ferritin (SF), serum Zn and Cu. Dietary adequacy was estimated using a food frequency questionnaire. Of all women, 4.7% had Fe deficiency (ID) anemia, 21 % ID without anemia, 26 % depleted Fe stores and 48.3% normal Fe status. Obese women had higher SF (p<0.01) compared with those classified as having normal BMI. Also, showed higher Hb (p<0.05) concentrations compared with overweight and normal weight women. Partidipants showed 3.5 % and 2.3 % of Zn and Cu deficiency, respectively. Also, 95 %, 94 % and 99 % had adequate intake of Fe, Zn and Cu respectively, according to EAR cut points. There were no significant differences in micronutrients intake across different nutritional status. There was a low prevalence of anemia, Fe, Zn and Cu deficiency. A high percentage of women reached micronutrient adequacy. However, 47% of women had ID without anemia and Fe depleted stores.
本研究的目的是评估智利育龄妇女的贫血状况、铁(Fe)、锌(Zn)和铜(Cu)的生化状态及膳食充足性。我们对来自智利圣地亚哥的86名年龄在18至48岁的妇女进行了一项便利抽样研究。我们通过血红蛋白(Hb)、平均红细胞体积、转铁蛋白饱和度、锌原卟啉、血清铁蛋白(SF)、血清Zn和Cu来确定贫血状况和微量营养素状态。膳食充足性通过食物频率问卷进行评估。在所有妇女中,4.7%患有缺铁(ID)性贫血,21%为缺铁但无贫血,26%铁储备耗尽,48.3%铁状态正常。肥胖妇女的SF水平高于体重指数正常的妇女(p<0.01)。此外,与超重和体重正常的妇女相比,肥胖妇女的Hb浓度也更高(p<0.05)。参与者中分别有3.5%和2.3%存在Zn和Cu缺乏。此外,根据EAR切点,分别有95%、94%和99%的妇女铁、锌和铜摄入量充足。不同营养状况的妇女在微量营养素摄入量方面没有显著差异。贫血、铁、锌和铜缺乏的患病率较低。高比例的妇女达到了微量营养素充足状态。然而,47%的妇女缺铁但无贫血且铁储备耗尽。
