Although household food security (HHFS) has been linked to academic performance in school children, its association with early childhood development has received less attention, particularly in low-income countries. We investigated the association of HHFS with subsequent language development of children at 18 months of age in rural Bangladesh.
We followed 1439 infants born in 2002-2003 to the mothers in Maternal and Infant Nutrition Intervention in Matlab study, a large intervention trial conducted in rural Bangladesh. A HHFS scale was created from data collected from mothers during pregnancy. At 18 months, children's language (expression and comprehension) development was assessed using a Bengali adaptation of MacArthur's Communicative Development Inventory which was based on mothers' report of their children's ability to comprehend and express words in different categories. General linear regression models were used to examine the association between HHFS and language development at 18 months of age adjusting for potential confounders.
Household food security was associated with language comprehension (B = 0.19, 95% CI = 0.09, 0.30, P < 0.001) and expression (B = 1.01, 95% CI = 1.00, 1.02, P < 0.01) at 18 months of age. Mean language comprehension and expression at 18 months of the children in higher quartiles of HHFS were higher (P < 0.05) than those of the children in lower quartiles.
Household food security is positively associated with subsequent language development of rural Bangladeshi children. Early language development has been reported to predict later child development. Therefore, strategies to ensure HHFS status in Bangladesh and similar settings should be considered for optimum child development.
尽管家庭粮食安全与学龄儿童的学业成绩有关，但其与幼儿发育的关联较少受到关注，尤其是在低收入国家。我们调查了孟加拉国农村地区家庭粮食安全与18个月大儿童随后语言发育之间的关联。
我们追踪了2002年至2003年在孟加拉国农村进行的一项大型干预试验——Matlab母婴营养干预研究中母亲所生的1439名婴儿。根据孕期从母亲那里收集的数据创建了一个家庭粮食安全量表。在18个月时，使用孟加拉语改编的麦克阿瑟沟通发展量表评估儿童的语言（表达和理解）发育情况，该量表基于母亲对孩子理解和表达不同类别单词能力的报告。使用一般线性回归模型来检验家庭粮食安全与18个月大儿童语言发育之间的关联，并对潜在混杂因素进行调整。
家庭粮食安全与18个月大儿童的语言理解（B = 0.19，95%置信区间 = 0.09，0.30，P < 0.001）和表达（B = 1.01，95%置信区间 = 1.00，1.02，P < 0.01）相关。家庭粮食安全处于较高四分位数的儿童在18个月时的平均语言理解和表达能力高于（P < 0.05）处于较低四分位数的儿童。
家庭粮食安全与孟加拉国农村儿童随后的语言发育呈正相关。据报道，早期语言发育可预测儿童后期的发育情况。因此，为实现儿童最佳发育，应考虑在孟加拉国及类似环境中确保家庭粮食安全状况的策略。
