Abstract：
Evidence on the association between children\'s food insecurity (FI) and dietary patterns (DPs) is scarce. This study assessed the association between children\'s FI and a priori and a posteriori-defined DPs in a Portuguese population-based sample of children. A cross-sectional study including 2800 children from the 10-year-old follow-up of the Generation XXI birth cohort was performed. Data on food security status, assessed by the Self-administered Food Security Survey Module for children (SAFSSMC), dietary intake and socio-demographics were collected. A previously developed Healthy Eating Index (HEI) was adapted for this study. Using the HEI score and its food groups, linear and logistic regression models were performed. Using latent class analysis, five a posteriori-defined DPs were identified. The DPs names considered an overall picture of the DP. Food security status as a categorical (food security/FI) and continuous variable (SAFSSMC raw score: higher scores representing higher FI) was used. Multinomial logistic regression models were used to assess the association between food security status and DPs. Children\'s FI (9·4 %) was inversely associated with the HEI score (β=-0·695;95%CI:-1·154,-0·235), representing worse diet quality. A higher SAFSSMC raw score was associated with low fruit and vegetables (OR=1·089;95%CI:1·023,1·159) and seafood and eggs consumption (OR=1·073;95%CI:1·009,1·142) and high consumption of meat and meat products (OR=1·091;95%CI:1·026,1·160), salty snacks (OR=1·067;95%CI:1·003,1·136) and soft drinks (OR=1·097;95%CI:1·031,1·168). The SAFSSMC raw score was positively associated with \'Low consumption\' (OR=1·119;95%CI:1·016,1·232), \'Energy-dense foods\' (OR=1·155;95%CI:1·028,1·298) and \'Snacking\' (OR=1·119;95%CI:1·006,1·245) DPs. FI was associated with worse dietary choices. Intervention strategies targeting food insecure children should be developed to promote healthy dietary habits.
摘要：
关于儿童食物不安全(FI)和饮食模式(DP)之间关联的证据很少。这项研究评估了葡萄牙基于人群的儿童样本中儿童的FI与先验和后验定义的DP之间的关联。进行了一项横断面研究，其中包括21代出生队列10岁随访的2800名儿童。粮食安全状况数据，由自我管理的儿童食品安全调查模块（SAFSSMC）评估，收集了饮食摄入量和社会人口统计学。先前开发的健康饮食指数（HEI）适用于该研究。使用HEI评分及其食物组，采用线性和逻辑回归模型.使用潜在的类分析，确定了五个后验定义的DP。DP的名称考虑了DP的整体情况。使用食品安全状态作为分类(食品安全/FI)和连续变量(SAFSSMC原始得分:较高得分代表较高FI)。使用多项逻辑回归模型来评估粮食安全状况与DP之间的关联。儿童FI（9·4%）与HEI评分呈负相关（β=-0·695；95CI：-1·154，-0·235），代表较差的饮食质量。较高的SAFSSMC原始评分与低水果和蔬菜（OR=1·089;95CI：1·023,1·159）以及海鲜和鸡蛋的消费量（OR=1·073;95CI：1·009,1·142）和高消费量有关肉类和肉类产品（OR=1·091;95CI：1·026,1·160），咸零食（OR=1·067；95CI：1·003,1·136）和软饮料（OR=1·097；95CI：1·031,1·168）。SAFSSMC原始评分与“低消费”呈正相关(OR=1·119；95CI:1·016,1·232)，“能量密集型食物”（OR=1·155；95CI：1·028,1·298）和“零食”（OR=1·119；95CI：1·006,1·245）DP。FI与较差的饮食选择有关。应制定针对食物不安全儿童的干预策略，以促进健康的饮食习惯。
