很少有研究调查儿童早餐摄入量与特定肥胖或胰岛素动力学指标之间的关系。本研究的目的是确定是否早餐消费与肥胖，特别是腹内脂肪组织（IAAT），和胰岛素动力学超重的拉丁美洲青年。参与者是93名超重（BMI>= 85 th百分位数）的拉丁美洲青年（10-17岁）的横断面样本，他们有2型糖尿病家族史。通过两次24小时回忆、IAAT和皮下腹部脂肪组织（SAAT）（通过磁共振成像）、身体组成（通过双能X射线吸收测定法）和胰岛素动力学（通过频繁采样的静脉内葡萄糖耐量试验和最小建模）评估饮食摄入量。参与者被分为三个早餐消费类别：那些报告在任何一天都不吃早餐的人（早餐跳过者; n = 20），那些报告在两天中的一天吃早餐的人（偶尔吃早餐者; n = 39）和那些在两天都吃早餐的人（早餐进食者; n = 34）。使用协方差分析，不吃早餐与IAAT增加相关（P = 0.003），与年龄、坦纳、性别、全身脂肪、全身瘦组织质量和每日能量摄入无关。在任何其他肥胖测量或胰岛素动力学方面，早餐类别之间没有显著差异。吃早餐与超重的拉丁美洲青年内脏脂肪减少有关。重点关注增加早餐消费的干预措施是必要的。
Few studies have investigated the relationship between breakfast consumption and specific adiposity or insulin dynamics measures in children. The goal of this study is to determine whether breakfast consumption is associated with adiposity, specifically intra-abdominal adipose tissue (IAAT), and insulin dynamics in overweight Latino youth. Participants were a cross-sectional sample of 93 overweight (>= 85th percentile BMI) Latino youth (10-17 years) with a positive family history of type 2 diabetes. Dietary intake was assessed by two 24-h recalls, IAAT, and subcutaneous abdominal adipose tissue (SAAT) by magnetic resonance imaging, body composition by dual-energy X-ray absorptiometry, and insulin dynamics by a frequently sampled intravenous glucose tolerance test and minimal modeling. Participants were divided into three breakfast consumption categories: those who reported not eating breakfast on either day (breakfast skippers; n = 20), those who reported eating breakfast on one of two days (occasional breakfast eaters; n = 39) and those who ate breakfast on both days (breakfast eaters; n = 34). Using analyses of covariance, breakfast omission was associated with increased IAAT (P = 0.003) independent of age, Tanner, sex, total body fat, total body lean tissue mass, and daily energy intake. There were no significant differences in any other adiposity measure or in insulin dynamics between breakfast categories. Eating breakfast is associated with lower visceral adiposity in overweight Latino youth. Interventions focused on increasing breakfast consumption are warranted.
