To examine the relationship between food insecurity and food supplies in Latino households.
Cross-sectional survey, conducted February to May 2001.
Six California counties.
Convenience sampling was used to recruit 274 low-income Latino families with preschool children from the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), Head Start, and other community-based organizations. Complete data were available for 256 families.
Food security, household food scores.
Pearson correlations, Kruskal-Wallis test, and logistics regression. Significance level at P <.05.
Controlling for maternal education, food insecurity over the past 3 months was associated with lower household food supplies: dairy, r = -.18, P <.01; fruit, r = -.36, P <.001; grains, r = -.27, P <.0001; meats, r = -.22, P <.001; snack foods, r = -.23, P <.001; and vegetables, r = -.29, P <.001.
In Latino households, greater food insecurity is associated with a lower variety of most foods, particularly fruits and vegetables. Future research in Latino households should explore the effects of seasonal food insecurity and household food shortages on food intake of individual household members, especially young children.
研究拉丁裔家庭中粮食不安全与食物供应之间的关系。
2001年2月至5月进行的横断面调查。
加利福尼亚州的六个县。
采用便利抽样法，从妇女、婴儿和儿童特别补充营养计划（WIC）、启蒙计划及其他社区组织中招募了274个有学龄前儿童的低收入拉丁裔家庭。256个家庭有完整数据。
粮食安全、家庭食物得分。
Pearson相关性分析、Kruskal-Wallis检验和逻辑回归分析。显著性水平为P <.05。
在控制母亲教育程度的情况下，过去3个月的粮食不安全与家庭食物供应量较低相关：乳制品，r = -.18，P <.01；水果，r = -.36，P <.001；谷物，r = -.27，P <.0001；肉类，r = -.22，P <.001；休闲食品，r = -.23，P <.001；蔬菜，r = -.29，P <.001。
在拉丁裔家庭中，粮食不安全程度越高，大多数食物的种类就越少，尤其是水果和蔬菜。未来对拉丁裔家庭的研究应探讨季节性粮食不安全和家庭食物短缺对家庭个别成员，尤其是幼儿食物摄入量的影响。
