Demographic characteristics and beverage choices may affect diet quality.
To estimate the independent associations between consumption of food categories of the US Department of Agriculture Food Guide Pyramid, beverage consumption, gender, age, family income, and race/ethnicity with the Healthy Eating Index (HEI).
Data from the Continuing Survey of Food Intake by Individuals 1994-96, 1998 were used to develop multiple regression models of demographics and food and beverage consumption regressed on the HEI.
After adolescence (13-19 years), males consistently had a lower diet quality than females. Young adults (20-29 years) had the poorest diet quality. Family income had a positive association with the HEI. Controlling for income, African-Americans had lower HEI scores than other race/ethnicity groups. Caucasians consumed significantly more milk products than did the other race/ethnicity groups. Consumption of beverages had a weak but positive association with the HEI.
Family income and race/ethnicity have unique and independent associations with the HEI and dietary patterns.
人口统计学特征和饮料选择可能会影响饮食质量。
评估美国农业部食物指南金字塔中的食物类别摄入量、饮料摄入量、性别、年龄、家庭收入以及种族/族裔与健康饮食指数（HEI）之间的独立关联。
使用1994 - 1996年、1998年个人食物摄入量持续调查的数据，建立以HEI为因变量，人口统计学特征以及食物和饮料摄入量为自变量的多元回归模型。
青春期（13 - 19岁）之后，男性的饮食质量始终低于女性。年轻人（20 - 29岁）的饮食质量最差。家庭收入与HEI呈正相关。在控制收入因素后，非裔美国人的HEI得分低于其他种族/族裔群体。高加索人摄入的奶制品明显多于其他种族/族裔群体。饮料摄入量与HEI呈微弱但正向的关联。
家庭收入和种族/族裔与HEI及饮食模式有着独特且独立的关联。
