Using data from the National Health and Nutrition Examination Survey, we examine the relationship between nutritional status, poverty, and food insecurity for household members of various ages. Our most striking result is that, while poverty is predictive of poor nutrition among preschool children, food insecurity does not provide any additional predictive power for this age group. Among school age children, neither poverty nor food insecurity is associated with nutritional outcomes, while among adults and the elderly, both food insecurity and poverty are predictive. These results suggest that researchers should be cautious about assuming connections between food insecurity and nutritional outcomes, particularly among children.
利用美国国家健康与营养检查调查的数据，我们研究了不同年龄段家庭成员的营养状况、贫困与粮食不安全之间的关系。我们最显著的结果是，虽然贫困可预测学龄前儿童的营养不良情况，但粮食不安全对该年龄组并无额外的预测作用。在学龄儿童中，贫困和粮食不安全均与营养结果无关，而在成年人和老年人中，粮食不安全和贫困都具有预测性。这些结果表明，研究人员在假设粮食不安全与营养结果之间的联系时应谨慎，尤其是在儿童中。
