Although the importance of fruit and vegetable consumption to health has been well established, few studies have focused on access to fruits and vegetables in rural areas; even fewer examined the relationship between food access and fruit and vegetable consumption among seniors.
To examine the spatial challenges to good nutrition faced by seniors who reside in rural areas and how spatial access influences fruit and vegetable intake. A cross-sectional analysis using data from the 2006 Brazos Valley Health Assessment (mailsurvey) for 582 rural seniors (60-90 years), who were recruited by random digit dialing; food store data from the 2006-2007 Brazos Valley Food Environment Project that used ground-truthed methods to identify, geocode, and inventory fruit and vegetables in all food stores.
Few of the BVHA seniors consumed the recommended intakes of fruits or vegetables; women consumed more servings of fruit (1.49 +/- 0.05 vs. 1.29 +/- 0.07, p = 0.02), similar servings of vegetables (2.18 +/- 0.04 vs. 2.09 +/- 0.07, p = 0.28), and more combined fruit and vegetables (3.67 +/- 0.08 vs. 3.38 +/- 0.12, p = 0.04) than men. The median distances to fresh fruit and vegetables were 5.5 miles and 6.4 miles, respectively. When canned and frozen fruit and vegetables were included in the measurement of overall fruit or vegetables, the median distance for a good selection of fruit or vegetables decreased to 3.4 miles for overall fruit and 3.2 miles for overall vegetables. Almost 14% reported that food supplies did not last and there was not enough money to buy more. Our analyses revealed that objective and perceived measures of food store access--increased distance to the nearest supermarket, food store with a good variety of fresh and processed fruit, or food store with a good variety of fresh and processed vegetables--were associated with decreased daily consumption of fruit, vegetables, and combined fruit and vegetables, after controlling for the influence of individual characteristics and perceptions of community and home food resources.
Findings suggest that interventions designed to increase fruit and vegetable consumption among rural seniors should consider strategies to ameliorate differential access to healthy food due to food store distance.
尽管水果和蔬菜的消费对健康的重要性已得到充分证实,但很少有研究关注农村地区的水果和蔬菜供应情况;更少的研究调查食物供应与老年人水果和蔬菜消费之间的关系。
本研究通过 2006 年布拉索斯河谷健康评估(邮件调查)的横断面数据分析,检测了居住在农村地区的老年人在良好营养方面所面临的空间挑战,以及空间可达性如何影响他们的水果和蔬菜摄入量。该研究共纳入了 582 名农村老年人(60-90 岁),采用随机数字拨号法招募他们作为研究对象。该研究还使用了 2006-2007 年布拉索斯河谷食品环境项目的食品店数据,该项目采用实地核实方法识别、地理编码和记录所有食品店的水果和蔬菜库存。
很少有 BVHA 老年人摄入推荐量的水果或蔬菜;女性摄入更多份的水果(1.49 +/- 0.05 比 1.29 +/- 0.07,p = 0.02),类似份量的蔬菜(2.18 +/- 0.04 比 2.09 +/- 0.07,p = 0.28),以及更多的混合水果和蔬菜(3.67 +/- 0.08 比 3.38 +/- 0.12,p = 0.04)。新鲜水果和蔬菜的中位数距离分别为 5.5 英里和 6.4 英里。当将罐装和冷冻水果和蔬菜纳入整体水果或蔬菜的测量中时,整体水果和整体蔬菜的良好选择的中位数距离分别减少到 3.4 英里和 3.2 英里。近 14%的人报告称食物供应不足,没有足够的钱购买更多的食物。我们的分析表明,客观和感知的食品店可达性指标——到最近的超市的距离增加、有各种新鲜和加工水果的食品店或有各种新鲜和加工蔬菜的食品店——与控制个人特征和社区及家庭食物资源的影响后,水果、蔬菜和混合水果和蔬菜的日摄入量减少有关。
研究结果表明,旨在增加农村老年人水果和蔬菜摄入量的干预措施应考虑缓解因食品店距离导致的健康食品获取差异的策略。
