2009年社会背景下行为风险因素监测系统的可选模块中纳入了一个重新设计的衡量粮食压力的粮食不安全问题。我们研究的目的是用这个问题作为食物不安全的替代品来研究食物压力和肥胖之间的关系。我们的分析样本包括来自12个州的66，553名成年人。粮食不安全程度取决于对以下问题的回答（总是/通常/有时）：“在过去12个月里，你多久会说你担心或担心没有足够的钱购买营养餐？“T检验用于比较各组之间的患病率差异，逻辑回归用于检查粮食不安全与肥胖之间的关联。在这12个州中，肥胖的患病率为27.1%，在食物安全的成年人中为25.2%，在食物不安全的成年人中为35.1%。与食物安全的成年人相比，食物不安全的成年人肥胖的几率增加了32%。与食物安全的成年人相比，食物不安全的成年人在以下人群亚组中的肥胖患病率显着更高：年龄>= 30岁的成年人，女性，非西班牙裔白人，非西班牙裔黑人，受过一定程度大学教育或大学学位的成年人，家庭收入1000美元的成年人。
A redesigned food insecurity question that measured food stress was included in the 2009 Behavioral Risk Factor Surveillance System in the Social Context optional module. The objective of our study was to examine the association between food stress and obesity using this question as a surrogate for food insecurity. Our analytic sample included 66,553 adults from 12 states. Food insecurity was determined by response (always/usually/sometimes) to the question, "How often in the past 12 months would you say you were worried or stressed about having enough money to buy nutritious meals?" T tests were used to compare prevalence differences between groups, and logistic regression was used to examine the association between food insecurity and obesity. Among the 12 states, the prevalence of obesity was 27.1% overall, 25.2% among food secure adults, and 35.1% among food insecure adults. Food insecure adults had 32% increased odds of being obese compared to food secure adults. Compared with food secure adults, food insecure adults had significantly higher prevalence of obesity in the following population subgroups: adults ages >= 30 years, women, non-Hispanic whites, non-Hispanic blacks, adults with some college education or a college degree, a household income of
