A retrospective cohort study of infant-feeding practices at 6 months of age was conducted for 382 breastfed infants in a semirural northern California county. The authors hypothesized that almost exclusive breastfeeding at 6 months would be related to maternal experiences in the hospital. Multiple logistic regression analysis, controlling for maternal age and education, found that almost exclusive breastfeeding at 6 months was positively associated with receiving a telephone number for breastfeeding help from the hospital (odds ratio, 6.45; 95% confidence interval, 1.23-33.9), use of a breast pump in the first 6 months (odds ratio, 2.19; 95% confidence interval, 1.01-4.76), and gestational age (odds ratio, 2.26; 95% confidence interval, 1.08-4.71 for a 4-week age difference), whereas formula supplementation at the hospital had a negative association (odds ratio, 0.27; 95% confidence interval, 0.13-0.56). Making postpartum breastfeeding support easily accessible and offering breast pumps at low or no cost may help to increase exclusive breastfeeding rates in this county.
对加利福尼亚州北部一个半农村县的 382 名母乳喂养婴儿进行了一项 6 个月龄婴儿喂养方式的回顾性队列研究。作者假设，6 个月龄时几乎完全母乳喂养将与产妇在医院的经历有关。通过多变量逻辑回归分析，控制了产妇年龄和教育程度，发现 6 个月龄时几乎完全母乳喂养与从医院获得母乳喂养帮助的电话号码（比值比，6.45；95%置信区间，1.23-33.9）、在头 6 个月内使用吸奶器（比值比，2.19；95%置信区间，1.01-4.76）和胎龄（比值比，每 4 周差异为 2.26；95%置信区间，1.08-4.71）呈正相关，而在医院补充配方奶则呈负相关（比值比，0.27；95%置信区间，0.13-0.56）。使产后母乳喂养支持更容易获得，并以低价或免费提供吸奶器可能有助于提高该县的纯母乳喂养率。
