Food insecurity and the relationship between household income and children's health and nutrition in Brazil
利用2006年巴西人口与健康调查数据，研究发现粮食不安全与儿童较差的营养和健康指标相关，且控制粮食不安全后，家庭收入与儿童健康的关系减弱但仍显著。
Empirical evidence indicates that children living in wealthier households have better health. Food insecurity could be related to lack of adequate nutrition experienced by poor children and may be pointed out as one of the possible explanations for this relationship. This paper investigates the association between food insecurity and children's health and nutrition and the role of the former in the child health income gradient. Using data from the 2006 Brazilian Demographic and Health Survey, the results show that children living in households with food insecurity have worse nutrition and health indicators. In addition, the relationship between household income and many children's health and nutrition measures weakens but remains significant when controlling for food insecurity.
