To assess the nutritional status and dietary practices of 0-24-month-old children living in Brazilian Amazonia.
Cross-sectional study. Information on children's dietary intakes was obtained from diet history data. Weight and length were measured for anthropometric evaluation. Fe status was assessed using fasting venous blood samples; Hb, serum ferritin and soluble transferrin receptor concentrations were measured.
The towns of Assis Brasil and Acrelândia in the state of Acre, north-west Brazil.
A total of sixty-nine randomly selected 0-24-month-old children.
Of these children, 40.3 % were anaemic, 63.1 % were Fe-deficient, 28.1 % had Fe-deficiency anaemia and 11.6 % were stunted. Breast-feeding was initiated by 97.1 % of mothers, followed by early feeding with complementary foods. The dietary pattern reflected a high intake of carbohydrate-rich foods and cow's milk, with irregular intakes of fruit, vegetables and meat. All infants and 92.3 % of toddlers were at risk of inadequate Fe intakes. Fe from animal foods contributed on average 0.5 % and 14.3 % to total dietary Fe intake among infants and toddlers, respectively.
Poor nutritional status and inadequate feeding practices in this study population reinforce the importance of exclusive breast-feeding during the first 6 months of life. Greater emphasis is required to improve the bioavailability of dietary Fe during complementary feeding practices.
评估生活在巴西亚马孙地区的 0-24 个月大儿童的营养状况和饮食行为。
横断面研究。通过饮食史数据获取儿童饮食摄入信息。体重和身长用于人体测量评估。使用空腹静脉血样评估铁状况;测量血红蛋白(Hb)、血清铁蛋白和可溶性转铁蛋白受体浓度。
巴西西北部阿克里州的阿西斯·布拉西尔和阿克里兰迪亚镇。
共随机选择了 69 名 0-24 个月大的儿童。
这些儿童中,40.3%贫血,63.1%铁缺乏,28.1%缺铁性贫血,11.6%发育迟缓。97.1%的母亲开始进行母乳喂养,随后早期添加补充食物。饮食模式反映出碳水化合物丰富的食物和牛奶摄入量高,水果、蔬菜和肉类摄入量不规律。所有婴儿和 92.3%的幼儿都存在铁摄入不足的风险。动物源性食物中的铁分别平均占婴儿和幼儿膳食铁总摄入量的 0.5%和 14.3%。
本研究人群的营养状况较差且喂养方式不当,这强调了在生命的前 6 个月内进行纯母乳喂养的重要性。在补充喂养实践中,需要更加重视提高膳食铁的生物利用度。
