背景：产后住院时间短可能导致妇女没有足够的时间接受母乳喂养帮助。提早出院的女性还可能承担家庭责任，从而影响母乳喂养。这项研究探讨了产后住院时间与停止母乳喂养之间的关系。方法：本研究使用了 1999 年至 2001 年加州母婴健康评估 (MIHA) 调查的 10,519 名受访者的数据。MIHA 是一项针对加州育龄妇女的年度全州分层随机样本、基于人群的研究。生存分析用于检查住院时间与母乳喂养时间长度之间的关系。妇女们被问及她们的婴儿出生时在医院住了多少天，是否母乳喂养，如果母乳喂养，停止母乳喂养时孩子的年龄。住院时间分为三类：标准住院时间（阴道分娩 2 晚，剖腹产 4 晚），或比标准住院时间短或长。结果：大约 88% 的女性开始母乳喂养。未经调整的停止母乳喂养的预测因素包括产后停留时间短或长；产妇年龄年轻；西班牙裔、非裔美国人或亚洲/太平洋岛民种族/民族；未婚；收入或教育水平低；初产；出生于美国 50 个州或哥伦比亚特区；怀孕期间吸烟；和婴儿出生体重低。在对潜在的混杂因素进行调整后，短期停留的女性终止母乳喂养的可能性仍略高于标准停留的女性（相对风险，1.11，95%置信区间1.01，1.23）。结论：早于标准建议住院时间出院的女性提前终止母乳喂养的风险有所增加。
Background: Short postpartum hospital stays may leave inadequate time for women to receive assistance with breastfeeding. Women leaving the hospital early may also have household responsibilities that could interfere with breastfeeding. This study examined the relationship between postpartum length of stay and breastfeeding cessation. Methods: This study used data from 10,519 respondents to the California Maternal and Infant Health Assessment (MIHA) surveys from 1999 to 2001. MIHA is an annual statewide stratified random sample, population-based study of childbearing women in California. Survival analysis was used to examine the relationship between length of stay and length of time breastfeeding. Women were asked about the number of nights their infant stayed in the hospital at birth, whether they breastfed, and if so, the age of the child when they stopped. Hospital stay was defined in three categories: standard (2 nights for a vaginal delivery, 4 nights for a cesarean section), or shorter or longer than the standard stay. Results: Approximately 88 percent of women initiated breastfeeding. Unadjusted predictors of breastfeeding cessation included short or long postpartum stay; young maternal age; Hispanic, African American, or Asian/Pacific Islander race/ethnicity; being unmarried; low income or education level; primiparity; being born in the 50 United States or the District of Columbia; smoking during pregnancy; and low infant birthweight. After adjustment for potential confounders, women with a short stay remained slightly more likely to terminate breastfeeding than women with a standard stay (relative risk, 1.11, 95% confidence interval 1.01, 1.23). Conclusion: Women who leave the hospital earlier than the standard recommended stay are at somewhat increased risk of terminating breastfeeding early.
