与亚洲其他地区相比，南亚营养不良率下降有限，原因之一可能是家庭粮食安全水平低。然而，关于家庭粮食安全决定因素的证据基础有限。为了制定旨在改善家庭粮食安全的政策，需要更好地了解家庭粮食安全的决定因素。2011年从随机抽样的2 809名育龄妇女中收集了家庭数据。样本来自孟加拉国农村三个地区的九个工会。进行了多项逻辑回归，以衡量家庭粮食安全的选定决定因素和充足的家庭粮食供应月数之间的关系，并进行了线性回归，以衡量相同的决定因素和妇女的饮食多样性得分之间的关联。分析发现，土地所有权，调整相对风险比（RRR）0.28（CI 0.18，0.42）;相对财富（中间三分位0.49（0.29，0.84）和顶部三分位0.18（0.10，0.33））;妇女识字率0.64（0.46，0.90）;接触媒体0.49（0.33，0.72）;妇女自由进入市场0.56（0.36，0.85），所有这些都大大降低了粮食不安全的风险。较大的家庭增加了粮食不安全的风险，调整后的相对危险率为1.46（CI 1.02，2.09）。菜园家庭0.20（0.11，0.31），富裕家庭0.46（0.24，0.68）和识字的妇女0.37（0.20，0.54）更有可能有更好的饮食多样性得分。家庭粮食不安全仍然是孟加拉国的一个主要公共卫生问题，家庭平均每年有四分之一的时间遭受粮食短缺。简单的调查和分析方法能够确定与家庭粮食安全有关的许多相互关联的因素，但财富和识字率是与改善粮食安全和饮食多样性有关的唯一两个决定因素。我们无法断定是否必须改善所有决定因素才能改善家庭粮食安全，但在设计和监测与这些决定因素有关的新政策和现有政策时，应认识到这些政策可能对人口的粮食安全和营养状况产生重大影响。
There has been limited decline in undernutrition rates in South Asia compared with the rest of Asia and one reason for this may be low levels of household food security. However, the evidence base on the determinants of household food security is limited. To develop policies intended to improve household food security, improved knowledge of the determinants of household food security is required. Household data were collected in 2011 from a randomly selected sample of 2,809 women of reproductive age. The sample was drawn from nine unions in three districts of rural Bangladesh. Multinomial logistic regression was conducted to measure the relationship between selected determinants of household food security and months of adequate household food provisioning, and a linear regression to measure the association between the same determinants and women’s dietary diversity score. The analyses found that land ownership, adjusted relative risk ratio (RRR) 0.28 (CI 0.18, 0.42); relative wealth (middle tertile 0.49 (0.29, 0.84) and top tertile 0.18 (0.10, 0.33)); women’s literacy 0.64 (0.46, 0.90); access to media 0.49 (0.33, 0.72); and women’s freedom to access the market 0.56 (0.36, 0.85) all significantly reduced the risk of food insecurity. Larger households increased the risk of food insecurity, adjusted RRR 1.46 (CI 1.02, 2.09). Households with vegetable gardens 0.20 (0.11, 0.31), rich households 0.46 (0.24, 0.68) and literate women 0.37 (0.20, 0.54) were significantly more likely to have better dietary diversity scores. Household food insecurity remains a key public health problem in Bangladesh, with households suffering food shortages for an average of one quarter of the year. Simple survey and analytical methods are able to identify numerous interlinked factors associated with household food security, but wealth and literacy were the only two determinants associated with both improved food security and dietary diversity. We cannot conclude whether improvements in all determinants are necessarily needed to improve household food security, but new and existing policies that relate to these determinants should be designed and monitored with the knowledge that they could substantially influence the food security and nutritional status of the population.
