To assess the impact of breakfast skipping and type of breakfast consumed on energy/nutrient intake, nutrient adequacy, and diet quality.
Cross-sectional.
The National Health and Nutrition Examination Survey (NHANES), 1999-2002.
Young adults (20-39 years, n = 2615).
A 24-hour dietary recall was used, with breakfast defined as self-reported. Covariate-adjusted sample-weighted means for the entire day's energy/nutrient intakes, mean adequacy ratio (MAR) for nutrient intakes, and diet quality (i.e., Healthy Eating Index [HEI]-2005) scores were compared using analysis of variance and Bonferroni's correction (p < 0.0167) among breakfast skippers (BS), ready-to-eat-cereal breakfast consumers (RTECC), and other breakfast consumers (OBC). Energy/nutrient intakes and food consumption at breakfast were also compared (p ≤ 0.05).
Twenty-five percent of young adults were BS, 16.5% were RTECC, and 58.4% were OBC. Intakes of total energy, percent energy from carbohydrate, and dietary fiber were higher in RTECC than in BS and OBC. Percent energy intake from added sugars was higher in BS than in RTECC and OBC. Compared with BS and RTECC, OBC consumed a lower percent energy from carbohydrates and total sugars, but consumed a higher percent energy from total fat and discretionary solid fats and had a higher cholesterol intake. Intakes of several micronutrients were higher in RTECC than in BS and OBC. Both MAR and total HEI scores were the highest in RTECC and higher in OBC than in BS. The HEI scores for intakes of whole fruits, total/whole grains, milk, and percent energy from solid fat/alcohol/added sugar were the highest in RTECC and higher in OBC than in BS. Compared with OBC, RTECC had a higher HEI score for the intake of saturated fat. At breakfast, RTECC consumed higher intakes of total fruits, whole grains, dairy products, carbohydrates and total sugars, dietary fiber, and several micronutrients than OBC, who consumed higher intakes of meat/poultry/fish, eggs, total fat, discretionary oils/solid fats, cholesterol, and sodium than RTECC.
Thus, RTECC had more favorable nutrient intakes and better diet quality than BS and OBC.
评估不吃早餐和所吃早餐类型对能量/营养素摄入、营养素充足程度和饮食质量的影响。
横断面研究。
美国国家健康和营养调查(NHANES),1999-2002 年。
年轻人(20-39 岁,n=2615)。
采用 24 小时膳食回顾法,早餐定义为自我报告。采用协变量调整的样本加权均值比较整个白天的能量/营养素摄入、营养素平均充足率(MAR)和饮食质量(即健康饮食指数[HEI]-2005 评分),采用方差分析和 Bonferroni 校正(p<0.0167),比较不吃早餐者(BS)、即食谷物早餐消费者(RTECC)和其他早餐消费者(OBC)之间的差异。还比较了早餐时的能量/营养素摄入和食物消费(p≤0.05)。
25%的年轻人是 BS,16.5%是 RTECC,58.4%是 OBC。RTECC 的总能量、碳水化合物供能百分比和膳食纤维摄入量高于 BS 和 OBC。BS 的添加糖供能百分比高于 RTECC 和 OBC。与 BS 和 RTECC 相比,OBC 碳水化合物和总糖的供能百分比较低,但总脂肪和可自由支配的固体脂肪及胆固醇的摄入量较高。RTECC 的几种微量营养素摄入量高于 BS 和 OBC。RTECC 的 MAR 和总 HEI 评分均最高,OBC 高于 BS。RTECC 的全水果、全谷物/粗粮、牛奶和固体脂肪/酒精/添加糖供能百分比的 HEI 评分最高,OBC 高于 BS。与 OBC 相比,RTECC 的饱和脂肪摄入量的 HEI 评分较高。在早餐时,RTECC 的总水果、全谷物、乳制品、碳水化合物和总糖、膳食纤维和几种微量营养素摄入量高于 OBC,而 OBC 的肉/禽/鱼、鸡蛋、总脂肪、可自由支配的油/固体脂肪、胆固醇和钠的摄入量高于 RTECC。
因此,RTECC 的营养素摄入量和饮食质量优于 BS 和 OBC。
