This study investigated breastfeeding outcomes and factors associated with duration of breastfeeding in cohorts of healthy term and sick/preterm infants.
Follow-up was conducted of 87 sick/preterm and 92 term healthy infants during the 9 months following discharge from two Western Australian hospitals.
When corrected for gestational age, breastfeeding duration did not differ between the entire cohort of sick/preterm and term healthy groups. Multivariable analysis showed that early cessation of breastfeeding was more likely for infants born at <33 weeks of gestation (hazard ratio [HR ]=2.05, 95% confidence interval [CI]=1.14-3.69), mothers who had previously breastfed for <6 months (HR=3.67, 95% CI=2.12-6.37), and for mothers who perceived breastfeeding to be important rather than very important (HR=2.58, 95% CI=1.59-4.20).
Maternal perceptions of breastfeeding as "important" rather than "very important" and previous breastfeeding duration of <6 months are negatively associated with breastfeeding duration; these factors can be identified and addressed during pregnancy and in the postnatal period. Preterm infants born at <33 weeks of gestation have a shorter breastfeeding duration than those born at a later gestation.
本研究调查了健康足月和患病/早产儿队列中的母乳喂养结果和与母乳喂养持续时间相关的因素。
对来自西澳大利亚两家医院的 87 名患病/早产儿和 92 名健康足月婴儿进行了 9 个月的随访。
当按胎龄校正时，患病/早产儿整组和健康足月组的母乳喂养持续时间没有差异。多变量分析显示，胎龄<33 周的婴儿（危险比[HR] = 2.05，95%置信区间[CI] = 1.14-3.69）、之前母乳喂养时间<6 个月的母亲（HR = 3.67，95% CI = 2.12-6.37）以及认为母乳喂养“重要”而不是“非常重要”的母亲更有可能早期停止母乳喂养（HR = 2.58，95% CI = 1.59-4.20）。
母亲将母乳喂养视为“重要”而不是“非常重要”以及之前的母乳喂养时间<6 个月与母乳喂养持续时间呈负相关；这些因素可以在怀孕期间和产后期间确定并加以解决。胎龄<33 周的早产儿母乳喂养持续时间短于胎龄较大的早产儿。
