Food resources and frequency of food use of 1,000 households in Claiborne County in southwestern Mississippi were studied and related to income and educational level of the family heads. Income and educational levels of the family heads were much lower than the national average. The data on food frequency use indicated that the meal patterns of these households could not provide sufficient nutrients for individual family members. Income and educational levels of the family heads correlated highly with food frequency scores. The households with higher incomes and more education had better food consumption patterns than those with lower incomes and less education. However, income had more effect on low nutrient intake than education.
对密西西比州西南部克莱本郡1000户家庭的食物资源及食物使用频率进行了研究，并将其与户主的收入和教育水平相关联。户主的收入和教育水平远低于全国平均水平。食物使用频率数据表明，这些家庭的饮食模式无法为每个家庭成员提供足够的营养。户主的收入和教育水平与食物频率得分高度相关。收入较高且受教育程度较高的家庭，其食物消费模式比收入较低且受教育程度较低的家庭更好。然而，收入对低营养摄入的影响比教育更大。
