The Healthy People Social Determinants of Health topic area is organized into 5 place-based domains. Food insecurity is defined as the disruption of food intake or eating patterns because of lack of money and other resources. Food insecurity may be long term or temporary. The risk for food insecurity increases when money to buy food is limited or not available. In , black non-Hispanic households were nearly 2 times more likely to be food insecure than the national average Among Hispanic households, the prevalence of food insecurity was Neighborhood conditions may affect physical access to food. Residents are at risk for food insecurity in neighborhoods where transportation options are limited, the travel distance to stores is greater, and there are fewer supermarkets. Adults who are food insecure may be at an increased risk for a variety of negative health outcomes and health disparities. For example, a study found that food-insecure adults may be at an increased risk for obesity. Future studies should consider characteristics of communities and households that influence food insecurity. Disclaimer: This summary of the literature on food insecurity as a social determinant of health is a narrowly defined review that may not address all dimensions of the issue.
Food insecurity is a major public health concern, and refers to the uncertainty, lack of, or inability to acquire nutritious food in a safe and socially acceptable manner. Food insecurity has been associated with obesity and unhealthy dietary patterns, both of which can have negative health consequences. A review of the current literature revealed an adverse association between food insecurity and dietary patterns is well supported. The association between food insecurity and obesity is strongest for women, with results for men and children being mixed. Evidence for long-term effects is limited due to a lack of longitudinal studies. Results from interventional studies have mostly yielded mixed results, and it is presently unclear how to best help food insecure individuals improve diet and weight. Poor diet and unhealthy weight place an individual at risk for an array of health consequences, including cardiovascular diseases. Food insecurity may be associated with both poor diet and unhealthy weight, but the relationship between food insecurity, dietary patterns, and weight gain is not fully understood. A better understanding of this relationship may be particularly useful in creating and implementing effective behavioral and lifestyle interventions for at-risk populations. Previous research on the relationship between food insecurity and dietary patterns has linked food insecurity with a lower consumption of healthy food groups and poor diet quality, particularly with regard to fruit and vegetable intake.
