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 (> or =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.
很少有研究调查儿童早餐摄入与特定肥胖指标或胰岛素动态指标之间的关系。本研究的目的是确定早餐摄入是否与超重拉丁裔青少年的肥胖,特别是腹内脂肪组织(IAAT)以及胰岛素动态变化有关。研究对象是93名超重(BMI≥第85百分位数)的拉丁裔青少年(10 - 17岁),他们都有2型糖尿病家族史,采用横断面抽样。通过两次24小时饮食回忆法评估饮食摄入量,通过磁共振成像测量IAAT和皮下腹部脂肪组织(SAAT),通过双能X线吸收法测量身体成分,并通过频繁采样静脉葡萄糖耐量试验和最小模型法测量胰岛素动态变化。参与者被分为三个早餐摄入类别:那些报告两天都不吃早餐的人(不吃早餐者;n = 20),那些报告两天中有一天吃早餐的人(偶尔吃早餐者;n = 39),以及两天都吃早餐的人(吃早餐者;n = 34)。使用协方差分析,不摄入早餐与IAAT增加有关(P = 0.003),且不受年龄、坦纳分期、性别、全身脂肪、全身瘦组织质量和每日能量摄入的影响。早餐类别之间在任何其他肥胖指标或胰岛素动态变化方面均无显著差异。在超重拉丁裔青少年中,吃早餐与较低的内脏脂肪有关。有必要开展旨在增加早餐摄入量的干预措施。
