A family's ability to provide for its children's nutritional needs is linked to the family's food security—that is, to its access at all times to adequate food for an active, healthy life for all household members.37 The food security status of households is based on self-reports of difficulty in obtaining enough food, reduced food intake, reduced diet quality, and anxiety about an adequate food supply. In some households classified as food insecure, only adults' diets and food intakes were affected, but in a majority of such households, children's eating patterns were also disrupted to some extent, and the quality and variety of their diets were adversely affected.38 In a subset of food-insecure households—those classified as having very low food security among children—a parent or guardian reported that at some time during the year one or more children were hungry, skipped a meal, or did not eat for a whole day because the household could not afford enough food.39
NOTE: Food-insecure households are those in which either adults or children or both were "food insecure," meaning that, at times, they were unable to acquire adequate food for active, healthy living because the household had insufficient money and other resources for food. Statistics for 1996–1998 and 2000 are omitted because they are not directly comparable with those for other years.

39 In reports prior to 2006, households with "very low food security among children" were described as "food insecure with hunger among children." The methods used to assess children's food security remained unchanged, so the statistics for 2005 and later years are directly comparable with those for 2004 and earlier years.
