Prevalence and predictors of food insecurity among low-income households in Los Angeles County.

OBJECTIVES To assess the prevalence and identify the predictors of food insecurity among households in Los Angeles County with incomes below 300% of the federal poverty level. METHODS The Six-Item Short Form of the US Department of Agriculture's Household Food Security Scale was used as part of a 1999 county-wide, population-based, telephone survey. RESULTS The prevalence of food insecurity was 24.4% and was inversely associated with household income. Other independent predictors of food insecurity included the presence of children in the household (odds ratio (OR) 1.7, 95% confidence interval (CI) 1.2-2.3) and a history of homelessness in the past five years (OR 5.6, 95% CI 3.4-9.4). CONCLUSION Food insecurity is a significant public health problem among low-income households in Los Angeles County. Food assistance programmes should focus efforts on households living in and near poverty, those with children, and those with a history of homelessness.
