To determine the nutrient composition of complementary foods consumed by 6-12-month-old South African infants.
Nutrient intake was determined for infants who were recruited to participate in a randomised controlled trial using a single 24-hour dietary recall.
SETTING/SUBJECTS: Infants aged 6-12 months (n=475) residing in The Valley of a Thousand Hills, a rural area in KwaZulu-Natal, South Africa.
Energy and protein intakes from complementary foods were adequate. Infants who consumed infant products (commercially available fortified infant cereals/ready-to-eat canned baby foods/formula milk powder) had significantly higher intakes of calcium, iron, zinc, vitamin A, thiamine, riboflavin, niacin, vitamin B6, vitamin B12 and vitamin C than infants who did not consume any infant products. For infants who consumed infant cereals (n=142), these cereals provided 51% of total iron intake. Infant cereals provided more than 25% of total intake for magnesium, thiamine, niacin and vitamin B12. For infants consuming ready-to-eat canned baby foods (n=77), these products contributed less than 15% of total intake for all the micronutrients. The nutrient density of the complementary diet was less than half the desired density for calcium, iron and zinc. Animal products were consumed by 17% of infants, 26% consumed dairy products and 18% consumed vitamin-A-rich fruit and vegetables during the 24-hour recall period.
The nutrient composition of complementary foods among rural South African infants was inadequate, especially for iron, zinc and calcium. Strategies should be developed to improve the nutritional quality of their diets.
确定6至12个月大的南非婴儿所食用辅食的营养成分。
通过单次24小时饮食回顾,确定参与一项随机对照试验的婴儿的营养摄入量。
地点/研究对象:居住在南非夸祖鲁-纳塔尔省农村地区千山谷的6至12个月大的婴儿(n = 475)。
辅食中的能量和蛋白质摄入量充足。食用婴儿产品(市售强化婴儿谷物/即食罐装婴儿食品/配方奶粉)的婴儿,其钙、铁、锌、维生素A、硫胺素、核黄素、烟酸、维生素B6、维生素B12和维生素C的摄入量显著高于未食用任何婴儿产品的婴儿。对于食用婴儿谷物的婴儿(n = 142),这些谷物提供了总铁摄入量的51%。婴儿谷物提供了镁、硫胺素、烟酸和维生素B12总摄入量的25%以上。对于食用即食罐装婴儿食品的婴儿(n = 77),这些产品对所有微量营养素的总摄入量贡献不到15%。辅食的营养密度低于钙、铁和锌所需密度的一半。在24小时回顾期内,17%的婴儿食用了动物产品,26%的婴儿食用了乳制品,18%的婴儿食用了富含维生素A的水果和蔬菜。
南非农村地区婴儿辅食的营养成分不足,尤其是铁、锌和钙。应制定策略来提高他们饮食的营养质量。
