对四年级儿童的饮食报告验证研究的数据进行分析，以调查体重指数（BMI）与每日参与学校膳食和观察到的学校膳食能量摄入的可能关系，以及这些关系是否因早餐地点（教室;自助餐厅）而异。在17，17和8所学校在三个学年收集数据。在这三年里，有六所、六所和七所学校在教室里吃早餐;其他所有学校都在自助餐厅吃早餐。关于180天的学校早餐和学校午餐参与在四年级的1 571名儿童（90%黑人; 53%女孩）的信息可在电子行政记录从学区。对儿童进行称重和测量，并计算BMI。每个子集的465名儿童（95%的黑人; 49%的女孩）被观察到在同一天吃学校早餐和学校午餐。以BMI为因变量，学校为随机效应进行混合效应回归;自变量为早餐参与、午餐参与、联合参与（同一天的早餐和午餐）、早餐平均观察能量摄入、午餐平均观察能量摄入、性别、年龄、早餐地点和学年。使用排除性别和年龄的汇总有序logistic回归模型对BMI类别（体重不足/健康体重;超重;肥胖;严重肥胖）进行重复分析。早餐参与，午餐参与和合并参与与BMI或BMI类别无关，无论模型是否包括观察到的学校膳食能量摄入。在学校膳食中观察到的能量摄入量与BMI和BMI类别显着正相关。对于总样本和子集，早餐地点与BMI显著相关;在教室吃早餐的儿童的平均BMI大于在自助餐厅吃早餐的儿童。在教室里吃早餐的卡路里明显多于在自助餐厅。对于四年级的儿童，结果提供了证据的BMI和观察到的能量摄入量在学校用餐，BMI和学校早餐在教室之间的正相关;然而，BMI和参与学校用餐没有显着关联。
Data from a dietary-reporting validation study with fourth-grade children were analyzed to investigate a possible relationship of body mass index (BMI) with daily participation in school meals and observed energy intake at school meals, and whether the relationships differed by breakfast location (classroom; cafeteria). Data were collected in 17, 17, and 8 schools during three school years. For the three years, six, six, and seven of the schools had breakfast in the classroom; all other schools had breakfast in the cafeteria. Information about 180 days of school breakfast and school lunch participation during fourth grade for each of 1,571 children (90% Black; 53% girls) was available in electronic administrative records from the school district. Children were weighed and measured, and BMI was calculated. Each of a subset of 465 children (95% Black; 49% girls) was observed eating school breakfast and school lunch on the same day. Mixed-effects regression was conducted with BMI as the dependent variable and school as the random effect; independent variables were breakfast participation, lunch participation, combined participation (breakfast and lunch on the same day), average observed energy intake for breakfast, average observed energy intake for lunch, sex, age, breakfast location, and school year. Analyses were repeated for BMI category (underweight/healthy weight; overweight; obese; severely obese) using pooled ordered logistic regression models that excluded sex and age. Breakfast participation, lunch participation, and combined participation were not significantly associated with BMI or BMI category irrespective of whether the model included observed energy intake at school meals. Observed energy intake at school meals was significantly and positively associated with BMI and BMI category. For the total sample and subset, breakfast location was significantly associated with BMI; average BMI was larger for children with breakfast in the classroom than in the cafeteria. Significantly more kilocalories were observed eaten at breakfast in the classroom than in the cafeteria. For fourth-grade children, results provide evidence of a positive relationship between BMI and observed energy intake at school meals, and between BMI and school breakfast in the classroom; however, BMI and participation in school meals were not significantly associated.
