目的：本研究的目的是测试 NICU 中经后 32 周和 36 周的成人平均字数与贝利婴幼儿发展量表第三版 (Bayley-III)、认知和语言分数的关系。据推测，接触较高字数的早产儿在 7 个月和 18 个月的校正年龄时会有更高的认知和语言分数。 方法：这项前瞻性队列研究包括 36 名出生体重为 1250 克的早产儿。在月经后 32 周和 36 周时，在新生儿重症监护病房 (NICU) 使用数字语言处理器进行了 16 小时的录音。对成人每小时的字数进行回归分析，并使用 Bayley-III 测量值校正出生体重。结果：NICU 中的成人字数与 7 个月和 18 个月的 Bayley-III 评分呈正相关。对于 32 周的记录，在调整出生体重的回归分析中，成人每小时字数独立地解释了语言综合得分方差的 12% (P = .04) 和 18 个月表达沟通得分方差的 20% (P = .008)。在为期 36 周的记录中，成人每小时字数独立地解释了 7 个月时认知综合评分差异的 26% (P = .0049)。 结论：NICU 中家长与早产儿交谈量的增加与较高的 7 个月和 18 个月校正年龄 Bayley-III 语言和认知评分相关。这些发现为从新生儿重症监护室开始进行语言干预提供了机会。
OBJECTIVE:The goal of this study was to test the association of mean adult word counts at 32 and 36 weeks' postmenstrual age in the NICU with Bayley Scales of Infant and Toddler Development, 3rd Edition (Bayley-III), cognitive and language scores. It was hypothesized that preterm infants exposed to higher word counts would have higher cognitive and language scores at 7 and 18 months' corrected age.METHODS:This prospective cohort study included 36 preterm infants with a birth weight 1250 g. Sixteen-hour recordings were made in the NICU by using a digital language processor at 32 and 36 weeks' postmenstrual age. Regression analyses were performed on adult word count per hour, with Bayley-III measures correcting for birth weight.RESULTS:Adult word counts in the NICU were positively correlated with 7- and 18-month Bayley-III scores. For the 32-week recording, in regression analyses adjusting for birth weight, adult word count per hour independently accounted for 12% of the variance in language composite scores (P = .04) and 20% of the variance in expressive communication scores at 18 months (P = .008). For the 36-week recording, adult word count per hour independently accounted for 26% of the variance in cognitive composite scores at 7 months (P = .0049).CONCLUSIONS:Increased amount of parent talk with preterm infants in the NICU was associated with higher 7- and 18-month corrected age Bayley-III language and cognitive scores. These findings offer an opportunity for language intervention starting in the NICU.
