To examine associations between Food Stamp (FS) participation, meals away from home (MAFH), body mass index (BMI), and waist circumference (WC).
Cross-sectional study.
Nationally representative.
Data from low-income, FS-eligible individuals (N = 945) ages 20-65 years, responding to the 2005-2006 National Health and Nutrition Examination Survey.
MAIN OUTCOME MEASURE(S): MAFH per week, BMI, and WC.
Multiple linear regression models were used to examine associations between FS participation and MAFH, BMI, and WC, adjusting for age, sex, race, and education level.
Food Stamp authorization was associated with fewer MAFH (P = .004). Among females, FS authorization was associated with higher BMI (P = .04) and WC (P = .04). Among females reporting amount of benefits in the prior month, more FS benefits received were associated with lower BMI (P = .03) and WC (P < .001).
Seemingly contradictory results regarding associations between FS authorization and FS benefits received in the previous month and BMI and WC should be explored further. Effective nutrition education and environmental change strategies are needed, particularly among female FS recipients.
探讨食品券（FS）参与、不在家就餐（MAFH）、体重指数（BMI）和腰围（WC）之间的关联。
横断面研究。
全国代表性。
年龄在 20-65 岁之间、符合 FS 条件的低收入人群的数据（N=945），来自 2005-2006 年全国健康和营养调查。
每周 MAFH、BMI 和 WC。
使用多元线性回归模型，调整年龄、性别、种族和教育水平后，检验 FS 参与与 MAFH、BMI 和 WC 之间的关联。
FS 授权与较少的 MAFH 相关（P=0.004）。在女性中，FS 授权与较高的 BMI（P=0.04）和 WC（P=0.04）相关。在报告上个月获得的福利金额的女性中，获得的 FS 福利越多，BMI（P=0.03）和 WC（P<0.001）越低。
FS 授权和上个月获得的 FS 福利与 BMI 和 WC 之间的关联似乎存在矛盾的结果，需要进一步探讨。需要有效的营养教育和环境变化策略，特别是针对女性 FS 接受者。
