Although household food security (HHFS) has been shown to affect diet, nutrition, and health of adults and also learning in children, no study has examined associations with infant feeding practices (IFP). We studied 1343 infants born between May 2002 and December 2003 in the Maternal and Infant Nutrition Intervention in Matlab study to investigate the effect of HHFS on IFP in rural Bangladesh. We measured HHFS using a previously developed 11-item scale. Cumulative and current infant feeding scales were created from monthly infant feeding data for the age groups of 1-3, 1-6, 1-9, and 1-12 mo based on comparison to infant feeding recommendations. We used lagged, dynamic, and difference longitudinal regression models adjusting for various infant and maternal variables to examine the association between HHFS and changes in IFP, and Cox proportional hazards models to examine the influence of HHFS on the duration of breast-feeding and the time of introduction of complementary foods. Better HHFS status was associated with poor IFP during 3-6 mo but was associated with better IFP during 6-9 and 9-12 mo of age. Although better HHFS was not associated with the time of introduction of complementary foods, it was associated with the type of complementary foods given to the infants. Intervention programs to support proper IFP should target mothers in food-secure households when their babies are 3-6 mo old and also mothers in food-insecure households during the 2nd half of infancy. Our results provide strong evidence that HHFS influences IFP in rural Bangladesh.
尽管家庭粮食安全已被证明会影响成年人的饮食、营养和健康以及儿童的学习，但尚无研究探讨其与婴儿喂养方式（IFP）之间的关联。在Matlab母婴营养干预研究中，我们对2002年5月至2003年12月出生的1343名婴儿进行了研究，以调查家庭粮食安全对孟加拉国农村地区婴儿喂养方式的影响。我们使用先前开发的11项量表来衡量家庭粮食安全。根据与婴儿喂养建议的比较，从1 - 3、1 - 6、1 - 9和1 - 12月龄组的每月婴儿喂养数据中创建累积和当前婴儿喂养量表。我们使用滞后、动态和差异纵向回归模型，并对各种婴儿和母亲变量进行调整，以研究家庭粮食安全与婴儿喂养方式变化之间的关联，还使用Cox比例风险模型来研究家庭粮食安全对母乳喂养持续时间和引入辅食时间的影响。更好的家庭粮食安全状况在3 - 6月龄时与不良的婴儿喂养方式相关，但在6 - 9月龄和9 - 12月龄时与更好的婴儿喂养方式相关。尽管更好的家庭粮食安全与引入辅食的时间无关，但它与给予婴儿的辅食类型有关。支持适当婴儿喂养方式的干预项目应针对粮食安全家庭中3 - 6月龄婴儿的母亲，以及婴儿期后半段粮食不安全家庭中的母亲。我们的研究结果提供了强有力的证据，证明家庭粮食安全会影响孟加拉国农村地区的婴儿喂养方式。
