目的是确定早餐的位置模式（早餐消费的频率和地点），并探索早餐模式与青春期前体重状况之间的关系。在一个中等城市学区随机选择的12所学校的学生中完成了调查和物理测量。所有学生从五年级（2011年秋季）一直被跟踪到七年级（2013年秋季）。本研究采用潜在转移分析和纵向分析。六种不同的早餐地点模式出现在基线(1)频繁跳船；(2)学校饮食不一致；(3)在家吃饭不一致；(4)经常在家吃饭的；(5)经常在学校吃早餐的人；(6)吃双份早餐的人。纵向分析的结果显示，在调整学校、学年和学生的种族/民族后，经常不吃早餐的人与吃两顿早餐的人相比，超重/肥胖的几率增加（AOR: 2.66, 95% CI: 1.67, 4.24）。每年吃两份早餐的学生和其他学生的体重变化相似。担心在学校吃第二顿早餐会增加体重增加的风险是没有根据的。经常在学校吃早餐的学生，包括吃两份早餐的学生，更有可能表现出健康的体重轨迹。需要更多的研究来了解普遍的学校早餐对学生整体饮食的影响。
The objectives are to identify breakfast location patterns (frequency and place of breakfast consumption) and explore the association between breakfast patterns and weight status over time among preadolescents. Surveys and physical measurements were completed among students from 12 randomly selected schools in a medium-sized urban school district. All students were followed from fifth (Fall, 2011) to seventh grade (Fall, 2013). Latent transition analysis and longitudinal analyses were used in the study. Six distinct breakfast location patterns emerged at baseline (1) frequent skippers; (2) inconsistent school eaters; (3) inconsistent home eaters; (4) regular home eaters; (5) regular school eaters and (6) double breakfast eaters. Results from the longitudinal analyses revealed that there was an increased odds of overweight/obesity among frequent skippers compared with double breakfast eaters after adjusting for school, year and students’ race/ethnicity (AOR: 2.66, 95% CI: 1.67, 4.24). Weight changes from year to year were similar between double breakfast eaters and other students. Concerns that a second breakfast at school increases risk of excessive weight gain are unsupported. Students who regularly consumed breakfasts at school, including double breakfast eaters, were more likely to exhibit a healthy weight trajectory. Additional research is needed to understand the impact of universal school breakfast on students’ overall diets.
