饮食模式方法经常被用来描述成人的饮食模式，但很少用于青少年。我们使用主成分因子分析：1）描述一组不同种族青年在青春期早期和中期的饮食模式; 2）检查这些模式是否在5年后持续存在; 3）研究长期趋势。项目EAT-I（时间1）收集了1998 - 1999年明尼苏达州31所学校4746名初中（年轻队列）和高中（老年队列）学生的数据。EAT-II项目（时间2）在2003 - 2004年重新调查了53%（n = 2516）的原始队列。在时间1和时间2使用青少年/青少年FFO评估饮食摄入量。我们按队列（年龄较大/较年轻）和性别（男孩/女孩）分别确定了饮食模式。在时间1，我们确定了4个模式，在早期和中期的青少年之间是相对一致的男孩和女孩，我们标记为蔬菜，水果，甜/咸零食，和淀粉类食物。纵向分析表明，模式相对稳定超过5年，除了一个新的快餐模式。对中年青少年年龄匹配的长期趋势（时间1的老年队列，时间2的年轻队列）的检查显示出类似的模式，但在时间2出现在中年青少年男孩中的快餐模式除外。我们确定了这个青少年人群的饮食模式，不同于通常在成年人中发现的饮食模式。不同性别和年龄组的模式相似，随着时间的推移也相对相似，除了一种新的快餐模式。J.营养139：323 - 328，2009.
A diet-patterns approach has often been used to describe eating patterns in adults but has rarely been used in adolescents. We used principal components factor analysis to: 1) describe the dietary patterns of a cohort of ethnically diverse youth during early and middle adolescence; 2) examine if the patterns persisted 5 y later; and 3) study secular trends. Project EAT-I (Time 1) collected data on 4746 middle school (younger cohort) and high school (older cohort) students in 31 Minnesota schools in 1998-1999. Project EAT-II (Time 2) resurveyed 53% (n = 2516) of the original cohort in 2003-2004. Dietary intake was assessed at Time 1 and 2 using the Youth/Adolescent FFO. We identified dietary patterns separately by cohort (older/younger) and gender (boys/girls). At Time 1, we identified 4 patterns in early and middle adolescents that were relatively consistent between boys and girls that we labeled vegetable, fruit, sweet/salty snack food, and starchy food. Longitudinal analyses indicated that patterns were relatively stable over 5 y, with the exception of a new fast food pattern. Examination of age-matched secular trends in middle adolescents (older cohort at Time 1, younger cohort at Time 2) showed similar patterns, with the exception of the fast food pattern that emerged at Time 2 among middle adolescent boys. We identified dietary patterns in this adolescent population that differed from those usually found in adults. Patterns were similar across gender and age cohorts and were relatively similar over time, with the exception a new fast food pattern. J. Nutr. 139: 323-328, 2009.
