Food shopping behaviors may help determine how local food environments influence fruit and vegetable (F/V) intake, especially among food insecure households.
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.
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.
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.
F/V intake was modeled using multivariable linear regression.
A sample of adults, of whom 21.3% were living in FI households, reported consuming F/V an average of 4.1 times daily. FI 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.
For FI 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.
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）的摄入量，尤其是在食物不安全的家庭中。
研究在一个低收入社区的居民中，家庭食物安全、食物获取和食物购买行为是否与 F/V 的摄入量有关。
研究设计为横断面研究。
参与者/设置：2014 年通过电话访谈从蒙特利尔（加拿大）的一个低收入社区中随机抽取了 451 名成年人作为简单随机样本，最终分析纳入了 417 名参与者。
采用经过验证的评估工具来衡量 F/V 的摄入量，并区分食物安全（FS）和食物不安全（FI）的参与者。根据参与者家庭道路网络缓冲区 0.5 英里内的食品店数量来计算社区食物获取情况。自我报告的食物购买行为包括购物频率、商店类型以及到达最常去的 3 家商店所使用的交通工具。参与者还报告了行动不便情况、使用 F/V 市场、园艺以及对健康食品的可及性的看法。
使用多变量线性回归模型来对 F/V 的摄入量进行建模。
成年人样本中，21.3%的人生活在 FI 家庭中，报告平均每天食用 F/V 4.1 次。FI 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、对健康食品的可及性以及食物购买行为。行动不便的参与者 F/V 摄入量较低（b=-0.68，P=0.02），而园艺与 F/V 摄入量较高有关（b=0.59，P=0.01）。超市数量（b=-0.06，P=0.03）和特色商店数量（b=0.10，P=0.04）与 F/V 的摄入量有关，尽管关联强度较弱。
对于 FI 家庭来说，与经济挑战相关的食物获取障碍与 F/V 摄入量较低有关。食物环境的研究应该包括人们对食物获取的体验，以更好地理解 FI 家庭面临的众多 F/V 消费障碍。
