Assessment of breastfeeding efficiency by objective means is essential to increase the success of breastfeeding.
To study the utility of LATCH score in predicting exclusive breastfeeding rates at 6 weeks postpartum along with an optimum cutoff between January 2016 and June 2016.
One hundred mother-infant dyads born of vaginal delivery with gestational age ≥37 weeks and singleton births were included with LATCH scores assessed at birth and 48 hours/discharge and followed up at 6 weeks postpartum.
Sixty-two of 100 (62%) infants were exclusively breastfeeding at 6 weeks. Mean LATCH scores at birth (7.17 ± 1.13 versus 4.26 ± 1.7, p = <0.0001) and 48 hours/discharge (9.22 ± 1.01 versus 5.78 ± 1.29, p = <0.0001) were higher in mothers who were breastfeeding at 6 weeks. LATCH score ≥6 at birth had a sensitivity 93.5% and specificity 65.78% and these mothers were 5.92 times more likely to be breastfeeding at 6 weeks. LATCH score ≥8 at 48 hours/discharge had a sensitivity 93.55% and specificity 92.1% with these mothers being 9.28 times more likely to be breastfeeding at 6 weeks postpartum. Receiver operating characteristic (ROC) for LATCH score at birth and exclusive breastfeeding (EBF) at 6 weeks had an area under curve (AUC) 0.915 (cutoff ≥5.5 sensitivity 93.5%, false positive rate-34.2%). ROC for LATCH score at 48 hours/discharge and EBF 6 weeks had an AUC 0.979 (cutoff ≥7.5 sensitivity 93.5%, false positive rate-7.9%).
LATCH represents a simple, cost-effective tool capable of predicting breastfeeding as early as in the first 24 hours of life, especially in resource-limited settings.
通过客观手段评估母乳喂养效率对于提高母乳喂养成功率至关重要。
研究2016年1月至2016年6月期间，LATCH评分在预测产后6周纯母乳喂养率方面的效用以及最佳临界值。
纳入100对母婴，母亲经阴道分娩，孕周≥37周且为单胎妊娠，在出生时、48小时/出院时评估LATCH评分，并在产后6周进行随访。
100名婴儿中有62名（62%）在产后6周进行纯母乳喂养。产后6周仍进行母乳喂养的母亲，其出生时的平均LATCH评分（7.17±1.13对4.26±1.7，p＜0.0001）和48小时/出院时的平均LATCH评分（9.22±1.01对5.78±1.29，p＜0.0001）更高。出生时LATCH评分≥6，敏感性为93.5%，特异性为65.78%，这些母亲在产后6周进行母乳喂养的可能性高5.92倍。48小时/出院时LATCH评分≥8，敏感性为93.55%，特异性为92.1%，这些母亲在产后6周进行母乳喂养的可能性高9.2倍。出生时LATCH评分与产后6周纯母乳喂养的受试者工作特征曲线（ROC）下面积（AUC）为0.915（临界值≥5.5，敏感性93.5%，假阳性率-34.2%）。48小时/出院时LATCH评分与产后6周纯母乳喂养的ROC下面积（AUC）为0.979（临界值≥7.5，敏感性93.5%，假阳性率-7.9%）。
LATCH是一种简单、经济有效的工具，能够早在出生后24小时内预测母乳喂养情况，尤其是在资源有限的环境中。
