To investigate relationships between weight resilience (maintaining a normal weight in a food desert environment) and fruit and vegetable (F&V) intake, attitudes and barriers.
Cross-sectional, in-person surveys collected May-December 2011, including self-reported data on F&V-related psychosocial factors, attitudes and barriers. Two 24 h dietary recalls were completed; weight and height were measured. Multivariable regression models estimated prevalence ratios (95 % CI).
Two low-income, predominantly African-American food deserts in Pittsburgh, Pennsylvania, USA.
Women aged 18-49 years (n 279) who were the primary food shopper in a household randomly selected for a parent study.
Fifteen per cent were weight resilient, 30 % were overweight and 55 % were obese. Overall, 25 % reported eating ≥5 F&V servings/d. After adjustment for age, education, parity, employment, living alone, physical activity, per capita income and mean daily energy intake, women eating ≥5 F&V servings/d were 94 % more likely to be weight resilient compared with those eating <5 servings/d (1·94; 1·10, 3·43). Across BMI groups, self-efficacy regarding F&V consumption was high and few F&V barriers were reported. The most frequently reported barrier was concern about the cost of F&V (36 %). Of the attitudinal F&V-related factors, only concern about wasting food when serving F&V was associated with weight resilience in adjusted models (0·29; 0·09, 0·94). In a model predicting consuming ≥5 F&V servings/d, driving one's own car to the store was the only attitudinal F&V-related factor associated with consumption (1·50; 1·00, 2·24).
In this population, weight resilience may be encouraged by improving access to affordable and convenient F&V options and providing education on ways to make them palatable to the entire household, rather than by shifting women's F&V perceptions, which are already positive.
探讨体重弹性（在食物匮乏环境中保持正常体重）与水果和蔬菜（F&V）摄入量、态度和障碍之间的关系。
2011 年 5 月至 12 月进行了横断面、面对面的调查，包括与 F&V 相关的心理社会因素、态度和障碍的自我报告数据。完成了两次 24 小时膳食回忆；测量了体重和身高。多变量回归模型估计了患病率比（95 %CI）。
美国宾夕法尼亚州匹兹堡两个低收入、以非裔美国人为主的食物荒漠。
年龄在 18-49 岁之间（n 279）的女性，她们是家庭中主要的食物购买者，家庭被随机选为父母研究的对象。
15 %的女性体重有弹性，30 %的女性超重，55 %的女性肥胖。总体而言，25 %的女性报告每天食用≥5 份 F&V。在调整年龄、教育程度、生育次数、就业、独居、体力活动、人均收入和日均能量摄入后，与每天食用<5 份 F&V 的女性相比，每天食用≥5 份 F&V 的女性体重弹性的可能性高 94 %（1·94；1·10，3·43）。在所有 BMI 组中，对 F&V 消费的自我效能感较高，报告的 F&V 障碍较少。报告最多的障碍是担心 F&V 的成本（36 %）。在与态度相关的 F&V 因素中，只有在供应 F&V 时担心浪费食物与调整后的模型中体重弹性相关（0·29；0·09，0·94）。在预测食用≥5 份 F&V 的模型中，自己开车去商店是与食用相关的唯一与态度相关的 F&V 因素（1·50；1·00，2·24）。
在这一人群中，通过改善获取负担得起和方便的 F&V 选择的机会，并提供有关使它们适合整个家庭的方法的教育，而不是通过改变女性已经积极的 F&V 观念，可能会鼓励体重弹性。
