背景：很少有研究研究总体饮食和心肺健康(CRF)之间的关系。目的：我们的目的是在黑人和白人成年人中调查食物种类、饮食质量评分和饮食结构与CRF的关系。设计：包括2632名年龄在38-50岁的参与者，他们参加了2005-2006年进行的青年冠状动脉风险发展(CARDIA)研究和青年冠状动脉风险发展(CFS)研究的第20年考试。通过使用有效的饮食历史来评估饮食。膳食评分和两种模式包括：先验饮食质量评分和主成分分析得出的肉类和水果-蔬菜饮食模式。CRF通过分级运动平板试验进行评估。结果：谷物(全谷物和精制谷物)、加工肉类和饮料(咖啡、代餐饮料、啤酒和葡萄酒)与跑步机持续时间总体呈正相关；全果(不是果汁)、器官肉、油炸肉类和鱼以及大豆和非乳制品与跑步机持续时间呈负相关。先验饮食质量得分与总的持续时间和所有种族性别亚组均呈正相关(P
Background: Few studies have investigated the association between overall diet and cardiorespiratory fitness (CRF).Objective: We aimed to investigate associations of food groups, a diet-quality score, and dietary patterns with CRF in black and white adults.Design: We included 2632 participants aged 38-50 y who attended the year 20 exam of the Coronary Artery Risk Development in Young Adults (CARDIA) study and Coronary Artery Risk Development in Young Adults Fitness Study (CFS) conducted in 2005-2006. Diet was assessed by using a validated diet history. A dietary score and 2 types of patterns were included as follows: the a priori diet-quality score and meat and fruit-vegetable dietary patterns derived from principal components analysis. CRF was assessed by using a graded exercise treadmill test. Linear regression models regressed the treadmill duration on food groups and dietary scores and patterns overall and in race-sex subgroups.Results: Grains (whole and refined), processed meats, and beverages (coffee, meal-replacement drinks, beer, and wine) were positively associated with the treadmill duration overall; whole fruit (not juices), organ meats, fried meats and fish, and soy and nondairy products were negatively associated. The a priori diet-quality score was positively associated with the duration overall and in all race-sex subgroups (P
