To assess the impact of early infant feeding practices on low birth weight- (LBW) specific neonatal mortality in rural Ghana.
A total of 11 787-breastfed babies were born between July 2003 and June 2004 and survived to day 2. Overall, 3411 (30.3%) infants had weight recorded within 48 h. Two hundred and ninety-six (8.7%) infants were <2.5 kg and 15 died in the neonatal period. Associations were examined using multivariate logistic regression.
Initiation of breastfeeding after day 1 was associated with a threefold increase in mortality risk (adjusted odds ratio (adjOR) 3.23, 95% confidence interval (95% CI) (1.07-9.82)) in infants aged 2 to 28 days. Prelacteal feeding was associated with a threefold significantly increased mortality risk (adjOR 3.12, 95% CI (1.19-8.22)) in infants aged 2 to 28 days but there was no statistically significant increase in risk associated with predominant breastfeeding (adjOR 1.91, 95% CI (0.60-6.09)). There were no modifications of these effects by birth weight. The sample size was insufficient to allow assessment of the impact of partial breastfeeding.
Improving early infant feeding practices is an effective, feasible, low-cost intervention that could reduce early infant mortality in LBW infants in developing countries. These findings are especially relevant for sub-Saharan Africa where many LBW infants are born at home, never taken to a health facility and mortality rates are unacceptably high.
评估加纳农村地区早期婴儿喂养方式对低出生体重儿(LBW)特定新生儿死亡率的影响。
2003年7月至2004年6月期间,共有11787名母乳喂养的婴儿出生并存活至第2天。总体而言,3411名(30.3%)婴儿在48小时内记录了体重。296名(8.7%)婴儿体重<2.5kg,其中15名在新生儿期死亡。使用多因素逻辑回归分析相关性。
出生后第1天之后开始母乳喂养与2至28日龄婴儿死亡风险增加三倍相关(调整优势比(adjOR)3.23,95%置信区间(95%CI)为(1.07 - 9.82))。初乳前喂养与2至28日龄婴儿死亡风险显著增加三倍相关(adjOR 3.12,95%CI为(1.19 - 8.22)),但纯母乳喂养相关风险无统计学显著增加(adjOR 1.91,95%CI为(0.60 - 6.09))。这些影响不受出生体重的影响。样本量不足以评估部分母乳喂养的影响。
改善早期婴儿喂养方式是一种有效、可行且低成本的干预措施,可降低发展中国家低出生体重儿的早期婴儿死亡率。这些发现对于撒哈拉以南非洲地区尤为重要,该地区许多低出生体重儿在家中出生,从未去过医疗机构,死亡率高得令人无法接受。
