Objective To analyze the effect of breakfast nutrition quality on the satiety among young white-collar workers.Methods A total of 278 subjects were recruited from two cities,Shenyang and Chongqing,in June 2015.The inclusion criteria:white-collar workers aged 25-45 years involved mainly in office work,who did not experience major changes,and individuals who should follow the study protocol and sign the informed consent form. The study employed a three-phase crossover design trial. Each participant received nutritional-adequate breakfast,nutritional-inadequate breakfast,and no breakfast treatment on the basis of assignment to one of three sequences. The breakfast time was once a week and then changed, all participants underwent the tests for three successive weeks.At last,we compared the effect of participants to consume different nutritional quality on satiety sense and hunger sense.Results A total of 232 participants completed three successive breakfast intervention studies, the age of participants was (35.2 ± 7.9) years, comprised of 48.7% male(n=113). The numbers of participants of aged 25-35 year-old and aged 36-45 were 118 and 114, respectively. Satiety scores of nutrition-adequate breakfast group, nutrition-inadequate breakfast group and no breakfast group were 63.5±14.7,53.1±10.2 and 36.4±7.2,respectively(P<0.05).In nutrition-inadequate breakfast group and no breakfast group,male subjects scored significantly higher than femalesubjects(50.9±10.5vs 46.6±9.4,35.2±8.3 vs 31.8±5.4)(P<0.05).And,participants aged 25-35 year-old. got satiety score significantly higher than aged 36-45(51.3±11.0 vs 45.6±12.1,34.1±6.8 vs 32.5±7.9),the difference was statistically significant (P<0.05). The scores of hunger in the group of nutrition-adequate breakfast, nutrition-inadequate breakfast and no breakfast were 26.3 ± 8.0, 35.1 ± 11.2 and 57.3 ± 17.0, respectively (P<0.05). Conclusion The nutrition quality of breakfast affects the satiety of young white-collar workers. The better the nutrition quality of breakfast is, the higher the satiety score and the lower the hunger score become. Compared with women and participants aged 36-45 year-old, men and those aged 25-35 year-old get satiety sense more easily.%目的 分析不同营养质量早餐对青年脑力劳动者饱腹感的影响.方法 于2015年6月在沈阳和重庆招募研究对象.纳入标准:年龄在25~45岁之间,从事脑力工作者,近期未经历重大变故者,能够遵从实验方案.共招募到278名受试者.采用三阶段交叉设计方法,每名研究对象均分别吃营养充分早餐1次,吃营养不充分早餐1次,不吃早餐1次,每周1次,1周后互换,连续3周.比较研究对象吃不同营养质量早餐后的饱感和饥饿感情况.结果 共有232名研究对象完成3次试验,年龄为(35.2±7.9)岁,其中男性113名(48.7%),25~35、36~45岁分别为118、114名.营养充分早餐、营养不充分早餐和不吃早餐组的饱感得分分别为63.5±14.7、53.1±10.2和36.4±7.2(P<0.05);营养不充分早餐组和不吃早餐组男性饱感得分均高于女性(50.9±10.5比6.6±9.4,35.2±8.3比31.8±5.4)(P值均<0.05);营养不充分早餐组和不吃早餐组中25~35岁研究对象饱感得分均高于36~45岁研究对象(51.3±11.0比45.6±12.1,34.1±6.8比32.5±7.9)(P值均<0.05).营养充分早餐、营养不充分早餐组和不吃早餐组的饿感得分分别为26.3±8.0、35.1±11.2和57.3±17.0(P<0.05).结论 早餐营养质量是影响青年脑力劳动者的饱腹感的主要因素;早餐营养质量越好,饱感得分越高,饥饿感得分越低;男性比女性,25~35比36~45岁研究对象更容易获得饱感.
