In the present analysis, we seek to establish a relationship between time spent on food-related activities and food security status as well as between time spent on these activities and Supplemental Nutrition Assistance Program (SNAP, formerly called the Food Stamp Program) participation and benefit level.
After matching similar households using Coarsened Exact Matching, we estimate the relationship between food-related time, food insecurity and SNAP participation and benefit level using a comprehensive data set that combines two subsets of the Current Population Survey from years 2004-2010: the Food Security Supplement and the American Time Use Survey.
City, suburban and rural areas of the USA.
Non-institutionalized US population over the age of 15 years. Total sample size is 10 247 households.
In single households, food insecurity and SNAP participation are associated with 20% more time in meal preparation and 13% less time eating. Similarly, in married households, SNAP participation and benefit level are associated with 32% less time in meal preparation while food insecurity is associated with 17% less time eating and 14% less time in grocery shopping.
A significant relationship exists between time spent on food-related activities and food insecurity and SNAP. This implies that federal and state government may need to consider the time constraints many low-income households face when reforming food assistance programmes.
在本分析中，我们试图确立花在与食物相关活动上的时间与粮食安全状况之间的关系，以及花在这些活动上的时间与补充营养援助计划（SNAP，前身为食品券计划）参与情况及受益水平之间的关系。
在使用粗化精确匹配法对相似家庭进行匹配后，我们利用一个综合数据集来估计与食物相关的时间、粮食不安全状况以及SNAP参与情况和受益水平之间的关系，该综合数据集结合了2004年至2010年当前人口调查的两个子集：粮食安全补充调查和美国时间使用调查。
美国的城市、郊区和农村地区。
15岁以上的非机构化美国人口。总样本量为10247户家庭。
在单身家庭中，粮食不安全状况和参与SNAP与多花20%的时间准备膳食以及少花13%的时间用餐有关。同样，在已婚家庭中，参与SNAP及受益水平与少花32%的时间准备膳食有关，而粮食不安全状况与少花17%的时间用餐以及少花14%的时间购物有关。
花在与食物相关活动上的时间与粮食不安全状况及SNAP之间存在显著关系。这意味着联邦和州政府在改革粮食援助计划时可能需要考虑许多低收入家庭面临的时间限制。
