The aim of this study is to investigate infant feeding patterns and to analyze the influence of breast-feeding methods on the prevalence of non-nutritive sucking habits in a sample of Japanese infants. A random sample of 353 mothers of infants of 18 months of age was interviewed at a public health facility in "K" city. The prevalence and duration of infant feeding patterns categorized as breast-feeding, partial breast-feeding, and bottle-feeding, were determined. The outcome investigated was the prevalence of non-nutritive sucking habits (pacifier use and finger sucking). The data were analyzed using the Chi-square and Fisher's exact tests with Bonferroni correction for multiple comparisons to assess possible association between feeding method and non-nutritive sucking behavior. The infants were categorized into the following groups depending on feeding method: breast-feeding (27.2%), partial breast-feeding (32.0%), or bottle-feeding (40.8%). Among all infants, 13.9% used a pacifier, 18.4% sucked their fingers, and 0.3% had both habits at 18 months of age. Breast-feeding was negatively correlated with pacifier use and finger sucking. In contrast, bottle-feeding was strongly associated with pacifier use and finger sucking. These results suggest that breast-feeding provides benefits to infants, and that non-nutritive sucking habits may be avoided by promoting correct breast-feeding practices.
本研究旨在调查日本婴儿的喂养模式，并分析母乳喂养方式对非营养性吸吮习惯发生率的影响。在“K”市的一家公共卫生机构，对353名18个月大婴儿的母亲进行了随机抽样访谈。确定了母乳喂养、部分母乳喂养和奶瓶喂养等婴儿喂养模式的发生率和持续时间。所调查的结果是非营养性吸吮习惯（使用安抚奶嘴和吮指）的发生率。使用卡方检验和费舍尔精确检验对数据进行分析，并采用Bonferroni校正进行多重比较，以评估喂养方式与非营养性吸吮行为之间的可能关联。根据喂养方式，婴儿被分为以下几组：母乳喂养（27.2%）、部分母乳喂养（32.0%）或奶瓶喂养（40.8%）。在所有婴儿中，13.9%的婴儿使用安抚奶嘴，18.4%的婴儿吮指，0.3%的婴儿在18个月大时同时有这两种习惯。母乳喂养与使用安抚奶嘴和吮指呈负相关。相比之下，奶瓶喂养与使用安抚奶嘴和吮指密切相关。这些结果表明，母乳喂养对婴儿有益，通过推广正确的母乳喂养方式可以避免非营养性吸吮习惯。
