In healthy infants, crying behavior is reduced significantly by "supplemental" carrying; that is, increased carrying throughout the day in addition to that which occurs during feeding and in response to crying. To determine whether the recommendation to increase carrying would be effective as a therapy for colic, 66 mothers of infants 4 weeks of age or less who came to their pediatricians with complaints of crying problems ("colic") were randomized to receive standard pediatric advice (standard group) or standard advice plus the recommendation to increase supplemental carrying by 50% (supplemental group). Overall, the supplemental group carried their infants 6.1 hours/d throughout the intervention period, an increase of 2.2 hours/d (56%) more than that provided by the standard group. Despite this significant increase in carrying, there was no difference between groups in the duration or frequency of crying, fussing, or cry/fuss at any time throughout the intervention period. When the greatest treatment effect was expected at 6 weeks, the supplemental group infants cried only 3 minutes less per day (95% confidence interval: 37 minutes less to 32 minutes more per day). We conclude that, compared with standard pediatric advice to be "responsive," supplemental carrying does not reduce crying and fussing behavior further in infants who have colic. In marked contrast to healthy infants, this apparent resistance to increased carrying may indicate an important difference in state regulation and control in infants with colic.
在健康婴儿中，“额外”抱抱能显著减少哭闹行为；也就是说，除了喂奶时以及回应婴儿哭闹时的抱抱外，全天增加抱抱次数。为了确定增加抱抱这一建议作为治疗腹绞痛的方法是否有效，66名带着哭闹问题（“腹绞痛”）前来儿科医生处就诊的4周龄及以下婴儿的母亲被随机分为两组，一组接受标准儿科建议（标准组），另一组接受标准建议并额外增加50%的抱抱次数（额外抱抱组）。总体而言，在整个干预期间，额外抱抱组每天抱婴儿6.1小时，比标准组多2.2小时/天（增加了56%）。尽管抱抱时间显著增加，但在整个干预期间的任何时候，两组在哭闹、烦躁或哭闹/烦躁的持续时间或频率上均无差异。在预计6周时会有最大治疗效果时，额外抱抱组的婴儿每天哭闹时间仅减少3分钟（95%置信区间：每天少37分钟至多32分钟）。我们得出结论，与标准的儿科“及时回应”建议相比，额外抱抱并不能进一步减少患有腹绞痛婴儿的哭闹和烦躁行为。与健康婴儿形成鲜明对比的是，这种对增加抱抱的明显抵抗可能表明患有腹绞痛的婴儿在状态调节和控制方面存在重要差异。
