The impact of ankyloglossia (tongue-tie) on breastfeeding outcomes may be overestimated and surgical treatment in newborns remains a controversial topic. The aim of the present study was to assess and quantify the impact of ankyloglossia in newborns on breastfeeding self-efficacy at 14 days of life.
A birth cohort study was conducted involving mothers and newborns soon after childbirth at a public hospital in the city of Canoas, southern Brazil. At the hospital, the lingual frenum of newborns were clinically examined and classified using the Bristol Tongue Assessment Tool. For every newborn with defined or suspected ankyloglossia, two newborns without ankyloglossia were co-enrolled for the study. At 14 days of the children's lives, the mothers were interviewed at home to collect data on breastfeeding self-efficacy using the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF). Poisson regression with robust variance was conducted to quantify differences in the Breastfeeding Self-Efficacy scores between exposed and nonexposed newborns after adjusting for maternal sociodemographic variables (mother's completed years of schooling, mother's age, family structure, progenitor status of child, mother's smoking status), the gestational variables (number of prenatal appointments, gestational age, comorbidities, type of childbirth), and child related variables (sex, birth weight, birth length) as confounders.
The final sample was composed of 31 children with ankyloglossia (exposed) and 57 without ankyloglossia (nonexposed). No significant differences were found in the BSEF-SF scores between the 31 children with ankyloglossia (mean BSEF-SF scores: 56.0; median BSEF-SF scores: 60; 95% CI: 51.9-60.1) and the 57 children without ankyloglossia (mean BSEF-SF scores: 59.6; median BSEF-SF scores: 60; 95% CI: 57.5-61.7). The Poisson regression analysis showed no significant difference in the BSEF-SF scores between newborns with ankyloglossia and those without ankyloglossia (Ratio = 0.95; 95% CI: 0.88-1.02; p = 0.139).
Ankyloglossia at birth exerted no clinically relevant impact on breastfeeding self-efficacy in children at 14 days of life.
舌系带过短（舌系带粘连）对母乳喂养结果的影响可能被高估，新生儿的手术治疗仍然是一个有争议的话题。本研究的目的是评估和量化新生儿舌系带过短对出生14天时母乳喂养自我效能的影响。
在巴西南部卡诺阿斯市的一家公立医院，对产后不久的母亲和新生儿进行了一项出生队列研究。在医院里，使用布里斯托尔舌评估工具对新生儿的舌系带进行临床检查和分类。对于每一个确诊或疑似舌系带过短的新生儿，另外纳入两名无舌系带过短的新生儿参与研究。在孩子出生14天时，在家中对母亲进行访谈，使用母乳喂养自我效能量表简表（BSES-SF）收集母乳喂养自我效能的数据。在调整了母亲的社会人口统计学变量（母亲的受教育年限、母亲年龄、家庭结构、孩子的祖辈状况、母亲的吸烟状况）、孕期变量（产前检查次数、孕周、合并症、分娩类型）以及与孩子相关的变量（性别、出生体重、出生身长）作为混杂因素后，采用稳健方差的泊松回归来量化暴露组和非暴露组新生儿在母乳喂养自我效能得分上的差异。
最终样本由31名舌系带过短的儿童（暴露组）和57名无舌系带过短的儿童（非暴露组）组成。31名舌系带过短的儿童（母乳喂养自我效能量表简表平均得分：56. ; 中位数得分：60 ; 95%可信区间：51.9 - 60.1）与57名无舌系带过短的儿童（母乳喂养自我效能量表简表平均得分：59.6 ; 中位数得分：60 ; 95%可信区间：57.5 - 61.7）在母乳喂养自我效能量表简表得分上未发现显著差异。泊松回归分析显示，舌系带过短的新生儿与无舌系带过短的新生儿在母乳喂养自我效能量表简表得分上无显著差异（比值 = 0.95 ; 95%可信区间：0.88 - 1.02 ; p = 0.139）。
出生时的舌系带过短对出生14天儿童的母乳喂养自我效能没有临床相关影响。
