Objective: To examine the prevalence of adult food insecurity as defined by fiscal insecurity and associated sociodemographic and behavioral factors.
Methods: The analytic sample included 96,111 adults in 14 states and DC using the 2015 BRFSS Social Context module. Food insecurity was determined by phone responses (always/usually/sometimes) to, "How often in the past 12 months would you say you were worried or stressed about having enough money to buy nutritious meals." In multivariable logistic regression analyses, predicted margins were estimated to represent the adjusted prevalence of food insecurity. Adjusted prevalence ratios (APR) were calculated by comparing the predictive margins within each population subgroup controlling for other sociodemographic and behavioral characteristics and weight status.
Results: The crude prevalence of food insecurity was 24.7% overall, and ranged from 17.1% in Minnesota to 31.1% in Arkansas. Minnesota and DC had significantly lower adjusted prevalence than the remaining states. The adjusted prevalence of food insecurity was significantly higher among women (APR=1.4); younger adults versus aged ≥70 years (APR=1.3 ̶ 2.1 by age group); non-Hispanic blacks (APR=1.1), Hispanics (ARR=1.3), and non-Hispanic others (APR=1.3) versus non-Hispanic whites; adults with lower education versus those with a college degree (APR=1.7 ̶ 2.2 by education level); unemployed adults (ARR=1.7) and those unable to work (ARR= 2.5) versus employed adults; those consuming <3 fruits and vegetables versus those consuming ≥5 daily (APR=1.1 ̶ 1.2 by count of fruit and vegetable intake); physically inactive versus highly active adults (APR=1.2); current (ARR=1.5) and former (APR=1.1) smokers versus nonsmokers; and adults with underweight (APR=1.2), overweight (APR=1.1), and obesity (APR=1.3) versus normal weight.
Conclusions: One quarter of adults reported concerns in the past year about having enough money to purchase nutritious foods. Multiple factors including lower fruit and vegetable intake and not having a normal weight were associated with food insecurity. The findings underline the importance for public health, social service agencies, and healthcare to monitor food insecurity and connect individuals to healthy and affordable food options.
