【 摘 要 】

Objective:To assess the energy and nutrient intakes of healthy infants from low-income families and to compare intakes with current recommendations.Design:We interviewed mother–infant pairs longitudinally when the infants were 3, 6, 9, 12, 18 and 24 months old. Food intake data were obtained by 24-hour dietary recalls. Selected nutrient intakes were calculated and compared with the Recommended Dietary Allowances (RDAs).Subjects/setting:Infants (n = 200) were the offspring of low-income, pregnant women recruited at the Albany County Department of Health, New York for the Albany Pregnancy and Infancy Lead Study, a prospective investigation of factors related to blood lead levels, including nutrition. Interviews were conducted during paediatric clinic visits.Statistical analyses performed:Means and standard deviations were used to describe energy and micronutrient intakes for age groups. The probability approach was utilised to examine the prevalence of inadequate intakes.Results:Mean energy and nutrient intakes generally met or exceeded the RDA. The exceptions were vitamin D and zinc for which observed means were below the RDA at several data points. Protein consumption was exceptionally high in this sample. The highest estimated prevalences of inadequate intakes were observed for iron, zinc and vitamin D at the older ages.Conclusions:This study identified several potential concerns about the diets of infants during the transition from infant food and formula to table foods. Low intakes of vitamin D, zinc and iron, especially at 12 and 18 months, were observed. High protein intakes were noted at all ages.
