This study examined the impact of cesarean section delivery on the initiation and duration of breast-feeding in the 1987 Mexican Demographic and Health Survey.
The subsample (n = 2517) was restricted to women whose delivery of their last-born children (aged 5 years and younger) was attended by a physician. Multivariate logistic regression was used to examine the association between cesarean section and likelihood of either not initiating breast-feeding or doing so for less than 1 month. Among women who breast-fed for 1 month or more, multivariate survival analysis was used to examine the relationship between cesarean section and breast-feeding duration.
Cesarean section was a risk factor for not initiating breast-feeding (odds ratio [OR] = 0.64, 95% confidence interval [CI] = 0.50, 0.82) and for breast feeding for less than 1 month (OR = 0.58, 95% CI = 0.37, 0.91) but was unrelated to breast-feeding duration among women who breast-fed for 1 month or more (OR = 0.97, 95% CI = 0.86, 1.11).
It is desirable to provide additional breast-feeding support during the early postpartum period to women who deliver via cesarean sections.
本研究在1987年墨西哥人口与健康调查中，考察了剖宫产分娩对母乳喂养开始时间和持续时间的影响。
子样本（n = 2517）仅限于其最后出生子女（5岁及以下）分娩时有医生在场的女性。采用多变量逻辑回归分析剖宫产与未开始母乳喂养或母乳喂养少于1个月可能性之间的关联。在母乳喂养1个月或更长时间的女性中，采用多变量生存分析来考察剖宫产与母乳喂养持续时间之间的关系。
剖宫产是未开始母乳喂养（优势比[OR]=0.64，95%置信区间[CI]=0.50，0.82）以及母乳喂养少于1个月（OR = 0.58，95% CI = 0.37，0.91）的一个风险因素，但与母乳喂养1个月或更长时间的女性的母乳喂养持续时间无关（OR = 0.97，95% CI = 0.86，1.11）。
对于剖宫产分娩的女性，在产后早期提供额外的母乳喂养支持是很有必要的。
