目标。我们的目的是评估母乳喂养对因出生后第一年感染过程而住院的可能性的影响。我们在1996年到1999年间跟踪了1385名婴儿，从出生到1岁。招募和数据收集是在6个月大的健康婴儿在国家儿童健康计划下进行的。记录全母乳喂养、住院以及与分娩、婴儿、母亲、卫生服务系统和社会学方面相关的其他相关变量。统计分析采用Kaplan-Meier检验、Cox回归获得风险比、调整归因风险。分娩后出院时和3、4、6个月时的全母乳喂养率分别为85%、52%、41%和15%；78人因感染而入院（38人因呼吸道感染，16人因胃肠道感染）。入院时平均年龄4.1个月。在估计了归因风险后，发现每多一个月的完全母乳喂养就可以避免30%的住院。看起来，100%的全母乳喂养4个月大的婴儿将避免56%的1岁以下婴儿住院。根据目前的数据，我们得出结论，在工业化国家，完全母乳喂养会降低因感染而住院的风险，这是1岁以下婴儿的结果。
OBJECTIVE. Our objective was to assess the effect of breastfeeding on the probability of hospitalization as a result of infectious processes during the first year of lifeMETHODS. We followed 1385 infants from birth to age 1 year between 1996 and 1999. Recruitment and data collection were done at the 6-month well-infant visit under the National Child Health Program. Full breastfeeding, hospital admission, and other relevant variables related to the delivery, infant, mother, health services system, and sociologic aspects were recorded. The statistical analysis included Kaplan-Meier test, Cox regression to obtain the hazard ratio, and the adjusted attributable risk.RESULTS. Full breastfeeding at discharge after delivery and at 3, 4, and 6 months of age were 85%, 52%, 41%, and 15%, respectively; 78 hospital admissions as a result of infections were recorded ( 38 respiratory tract, 16 gastrointestinal tract). Mean age at admission was 4.1 months. After estimating the attributable risk, it was found that 30% of hospital admissions would have been avoided for each additional month of full breastfeeding. Seemingly, 100% of full breastfeeding among 4-month-old infants would avoid 56% of hospital admissions in infants who are younger than 1 year.CONCLUSIONS. On the basis of the present data, we conclude that full breastfeeding would lower the risk for hospital admission as a result of infections among infants who are younger than 1 year within an industrialized country.
