Ten breast-fed infants, each paired with a formula-fed infant, were evaluated prospectively from birth to the age of 112 days to identify respiratory and gastrointestinal (GI) illnesses and microorganisms associated with respiratory tract infections. The infants were matched by age and sex. More GI illnesses occurred among the formula-fed infants. Although the breast-fed infants had less exposure to tobacco smoke in the home and less exposure to other children in day-care settings, there was no suggestion of a decrease in the frequency of respiratory illness during the first four months.
十对婴儿，每对中一个是母乳喂养婴儿，另一个是配方奶喂养婴儿，从出生到112天进行了前瞻性评估，以确定与呼吸道感染相关的呼吸道和胃肠道（GI）疾病及微生物。这些婴儿按年龄和性别进行匹配。配方奶喂养婴儿发生的胃肠道疾病更多。尽管母乳喂养婴儿在家中接触烟草烟雾较少，在日托环境中接触其他儿童较少，但在前四个月期间呼吸道疾病频率并无下降迹象。
