The goal was to determine whether an office-based, educational intervention for parents of 9-month-old children could reduce bottle use and iron depletion at 2 years of age.
Between January 2006 and 2007, 251 healthy, 9-month-old infants attending a routine health maintenance visit were assigned randomly to intervention or control groups. Parents in the intervention group were introduced to a 1-week protocol to wean their children from the bottle. Iron depletion (ferritin levels of <10 microg/L) and bottle use at 2 years were assessed.
A total of 201 children were monitored to 2 years of age (follow-up rate: 81%). Rates of iron depletion (10 [10%] of 102 children vs 13 [13%] of 99 children; P = .42) and milk consumption of >16 oz (16 [16%] of 102 children vs 17 [17%] of 99 children; P = .7) were not significantly different between the 2 groups at 2 years of age. However, children in the intervention group started using a cup 3 months earlier (9 vs 12 months; P = .001), were weaned from the bottle 4 months earlier (12 vs 16 months; P = .004), and were more than one-half as likely to be using a bottle at 2 years of age (15 [15%] of 102 children vs 39 [40%] of 99 children; P = .0004).
This simple intervention administered during a health maintenance visit did not result in a decrease in iron depletion at 2 years of age but did result in a 60% reduction in prolonged bottle use.
旨在探讨针对 9 个月大婴儿的父母的基于办公室的教育干预是否可以减少奶瓶使用和 2 岁时缺铁。
2006 年 1 月至 2007 年期间，251 名健康的 9 个月大婴儿在接受常规健康维护就诊时被随机分配到干预组或对照组。干预组的父母被介绍了一项为期 1 周的计划，以帮助他们的孩子戒掉奶瓶。在 2 岁时评估缺铁（铁蛋白水平<10μg/L）和奶瓶使用情况。
共有 201 名儿童在 2 岁时进行了监测（随访率：81%）。两组在 2 岁时的缺铁发生率（10[10%]例 102 名儿童与 13[13%]例 99 名儿童；P =.42）和牛奶摄入量>16 盎司（16[16%]例 102 名儿童与 17[17%]例 99 名儿童；P =.7）无显著差异。然而，干预组的儿童更早开始使用杯子（9 个月与 12 个月；P =.001），更早断奶（12 个月与 16 个月；P =.004），在 2 岁时使用奶瓶的可能性也降低了一半以上（15[15%]例 102 名儿童与 39[40%]例 99 名儿童；P =.0004）。
这项在健康维护就诊期间进行的简单干预并没有降低 2 岁时的缺铁发生率，但确实使长期使用奶瓶的比例降低了 60%。
