背景食物购买行为可能有助于确定当地食物环境如何影响水果和蔬菜（F/V）摄入，特别是在食物不安全的家庭中。和食品购物行为与低收入社区居民的F/V摄入量相关。设计研究设计是横断面的。参与者/设置一个简单的随机抽样的451名成年人从一个低收入社区，蒙特利尔（加拿大）的收入社区在2014年通过电话面试招募。最终分析包括417名参与者。主要结果测量验证的评估工具，以衡量F/V摄入量和区分粮食安全（FS）从粮食不安全（FI）的参与者。根据参与者住宅道路网络缓冲区0.5英里内的食品商店数量计算社区食品获取。自我报告的食品购物行为包括旅行频率，商店类型和交通工具，以达到3个最经常光顾的商店。与会者还报告了流动性的限制，使用F/V市场，园艺，并认为获得健康的food.Statistical分析F/V摄入量建模使用多变量线性regression. ResultsA样本的成年人，其中21.3%的人生活在英尺的家庭，报告消费F/V平均每天4.1次。Ft参与者的F/V摄入量较低（B =-0.69，P = 0.04），独立于社会人口统计学、食物获取、资源限制、健康食品感知获取和食品购物行为。活动受限的参与者F/V摄入量较低（B =-0.68，P = .02），而园艺与F/V摄入量较高相关（B = 0.59，P = .01）。多家超市（B =-0.06，P = .03）和专卖店（B = 0.10，P = 0.04）与F/V摄入量相关，尽管这种关联的强度很弱。与财政挑战有关的粮食获取障碍与F/五、食物环境研究应包括人们获得食物的经历，以更好地了解第一产业家庭在食品/食品消费方面面临的众多障碍。
Background Food shopping behaviors may help determine how local food environments influence fruit and vegetable (F/V) intake, especially among food insecure households.Objective To examine whether household food security, food access, and food shopping behaviors are associated with F/V intake among residents of a low-income neighborhood.Design Study design is cross-sectional.Participants/setting A simple random sample of 451 adults from a low-income neighborhood in Montreal (Canada) were recruited through telephone interviews in 2014. Final analyses included 417 participants.Main outcome measures Validated assessment tools were applied to measure F/V intake and to distinguish food secure (FS) from food insecure (FI) participants. Neighborhood food access was calculated according to number of food stores within 0.5 miles of road network buffer of participants' homes. Self-reported food shopping behaviors included trip frequency, store types, and transport used to reach the 3 most frequented stores. Participants also reported on mobility constraints, use of F/V markets, gardening, and perceived access to healthy food.Statistical analyses F/V intake was modeled using multivariable linear regression.Results A sample of adults, of whom 21.3% were living in Ft households, reported consuming F/V an average of 4.1 times daily. Ft participants had a lower intake of F/V (b = -0.69, P = .04), independent of sociodemographics, food access, resource constraints, perceived access to healthy food, and food shopping behaviors. Participants with mobility constraints had lower F/V intake (b = -0.68, P = .02), while gardening was associated with higher F/V intake (b = 0.59, P = .01). Number of supermarkets (b = -0.06, P = .03) and specialty stores (b = 0.10, P = .04) were associated with F/V intake, although the strength of the association was weak.Conclusions For Ft households, barriers to food access linked to financial challenges are associated with lower intake of F/V. Studies on food environment should include people's experience of food access to better understand the numerous barriers to F/V consumption faced by FI households.
