Sammanfattning	The HFSM is the official U.S. government measure of household food security, used in the Current Population Survey and National Health and Nutrition Examination Survey since 1995. The 18-item full form and 6-item short form assess the frequency and severity of food insecurity within a household based on direct reports of food access constraints, dietary adjustments, and hunger. The HFSM is the standard for U.S. food security surveillance and policy evaluation.	The HDDS is a simple, 12-item food group checklist that captures the diversity of the household diet in the preceding 24 hours. Developed by the FAO in 2011 as a proxy indicator of dietary quality and nutrient adequacy, the HDDS enables rapid assessment of the nutritional vulnerability of households in resource-limited settings. A household with access to foods from many groups is more likely to consume adequate calories, protein, and micronutrients.
