To evaluate the impact of breakfast consumption patterns on the nutritional adequacy of diets of young adults and determine possible ethnic and gender differences.
Cross-sectional survey of young adults in Bogalusa, La.
Twenty-four-hour dietary recalls were collected from October 1988 through October 1991 on 504 young adults (mean age=23 years, 58% women, 70% white).
Analysis of variance and logistic regression techniques were used to investigate the relationship of breakfast consumption, ethnicity, and gender on dietary adequacy. The P values are from an analysis of variance model that adjusted for gender and ethnicity.
Thirty-seven percent of young adults skipped breakfast. Of those who ate breakfast, 75% ate at home, 10% ate a fast-food breakfast, and 15% reported other sources. Mean energy intake from breakfast was 485 kcal; men consumed more energy than women (P<.001), and blacks consumed more energy than whites (P<.01). The breakfast meal provided an average of 13% of energy from protein, 55% from carbohydrate, 14% from sucrose, 34% from fat, and 12% from saturated fat. Whites consumed a breakfast higher in carbohydrate and sucrose than blacks, who consumed a breakfast higher in fat and saturated fat. Variations in breakfast foods consumed explained the racial differences in the nutrient composition of the breakfast meal. Young adults who skipped breakfast had lower total daily intakes of energy (P<.0001), protein per 1,000 kcal (P<.05), and saturated fat per 1,000 kcal (P<.01) than those who consumed breakfast. For all vitamins and minerals studied, a higher percentage of young adults who skipped breakfast did not meet two thirds of the Recommended Dietary Allowance than those who consumed a breakfast.
Encouraging consumption of breakfast, along with selection of more healthful breakfast food choices or snacks that are culturally appropriate, may be important strategies for improving the nutritional quality of young adults' diets.
评估早餐食用模式对年轻成年人饮食营养充足性的影响,并确定可能存在的种族和性别差异。
对路易斯安那州博加卢萨的年轻成年人进行横断面调查。
1988年10月至1991年10月期间收集了504名年轻成年人(平均年龄23岁,58%为女性,70%为白人)的24小时饮食回忆。
采用方差分析和逻辑回归技术研究早餐食用情况、种族和性别与饮食充足性之间的关系。P值来自一个对性别和种族进行了调整的方差分析模型。
37%的年轻成年人不吃早餐。在吃早餐的人中,75%在家吃,10%吃快餐早餐,15%报告有其他来源。早餐的平均能量摄入量为485千卡;男性摄入的能量比女性多(P<0.001),黑人摄入的能量比白人多(P<0.01)。早餐提供的能量中,蛋白质平均占13%,碳水化合物占55%,蔗糖占14%,脂肪占34%,饱和脂肪占12%。白人早餐中碳水化合物和蔗糖的含量高于黑人,而黑人早餐中脂肪和饱和脂肪的含量更高。所食用早餐食物的差异解释了早餐营养成分的种族差异。不吃早餐的年轻成年人每日总能量摄入量(P<0.0001)、每1000千卡蛋白质摄入量(P<0.05)和每1000千卡饱和脂肪摄入量(P<0.01)均低于吃早餐的人。对于所研究的所有维生素和矿物质,不吃早餐的年轻成年人中未达到推荐膳食摄入量三分之二的比例高于吃早餐的人。
鼓励食用早餐,同时选择更健康、符合文化习惯的早餐食物或零食,可能是改善年轻成年人饮食营养质量的重要策略。
