Childhood undernutrition is a major public health problem in Bangladesh. Evaluating child nutrition programs is a priority. The objective of this study was to evaluate a community-based nutrition education program (implemented from 2011 to 2013) aimed at improving infant and young child feeding (IYCF) practices and growth in rural Bangladesh. A cohort-based evaluation was conducted that included 2400 women (1200 from Karimganj, the intervention subdistrict, and 1200 from Katiadi, the control subdistrict) enrolled at 28-31 wk gestation in 3 waves between January and October 2011. Follow-up occurred at 3, 9, 16, and 24 mo of offspring age. The main outcomes were exclusive breastfeeding (EBF), measured at 3 mo, timing of complementary feeding (CF) initiation and minimum acceptable diet (MAD), measured at 9 mo, and child growth [assessed via length-for-age score (LAZ) and weight-for-length score], measured at all follow-ups. The main exposures were subdistrict of residence and wave of enrollment. For IYCF practices as outcome, logistic regressions were used. Generalized estimating equations were used for child growth as outcome. EBF rates at 3 mo remained unchanged between waves 1 and 3 in Karimganj (55.6% compared with 57.3%), but the proportion of infants receiving timely CF initiation and MAD at 9 mo increased significantly (CF: 27.1-54.7%; MAD: 8.4-35.3%). Mean LAZ at 24 mo remained unchanged between waves 1 and 3 in Karimganj (-2.18 compared with -1.98). The program was successful in improving the quality of infant diet at 9 mo and timely CF initiation, but not EBF at 3 mo or LAZ. These findings support the case for implementing simple messages in all programs aimed at improving infant diet, especially in settings in which supplementing overall household diet may not be feasible.
儿童营养不良是孟加拉国的一个主要公共卫生问题。评估儿童营养项目是当务之急。本研究的目的是评估一项基于社区的营养教育项目(2011年至2013年实施),该项目旨在改善孟加拉国农村地区婴幼儿喂养(IYCF)习惯和儿童生长情况。进行了一项基于队列的评估,纳入了2400名女性(干预分区卡里姆甘杰1200名,对照分区卡蒂亚迪1200名),她们于2011年1月至10月分3批在妊娠28 - 31周时入组。在子代3、9、16和24月龄时进行随访。主要结局指标包括3月龄时的纯母乳喂养(EBF)、9月龄时的辅食添加起始时间和最低可接受饮食(MAD),以及在所有随访时评估的儿童生长情况[通过年龄别身长评分(LAZ)和身长别体重评分进行评估]。主要暴露因素是居住分区和入组批次。对于以IYCF习惯为结局指标的情况,使用逻辑回归分析。对于以儿童生长为结局指标的情况,使用广义估计方程。卡里姆甘杰第1批和第3批之间,3月龄时的EBF率保持不变(分别为55.6%和57.3%),但9月龄时接受适时辅食添加起始和MAD的婴儿比例显著增加(辅食添加起始:27.1% - 54.7%;MAD:8.4% - 35.3%)。卡里姆甘杰第1批和第3批之间,24月龄时的平均LAZ保持不变(分别为 - 2.18和 - 1.98)。该项目成功改善了9月龄时的婴儿饮食质量和适时辅食添加起始情况,但未改善3月龄时的EBF或LAZ。这些研究结果支持在所有旨在改善婴儿饮食的项目中传递简单信息的必要性,特别是在无法对家庭整体饮食进行补充的情况下。
