ABSTRACT

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 female subjects (50.9±10.5 vs 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.

ABSTRACT

Objective To assess the differences in nutrient composition by chemical analysis method and weighing method,A corps of armed police forces daily dietary nutrient intakes were investigated in Tianjin,to understand the status of the actual intakes of dietary nutrient.Methods A dietary survey was performed using the weighing method and with ref-erence to China food composition database in 2002.The intake of each nutrient was calculated through chemical analysis;Nutritional analysis was used in the collection of duplicate food portions during the dietary survey.Results For most of the main dietary nutrients(protein,fat and carbohydrates),minerals (Na,K,Mg,Ca,Zn,Cu and Se)and vitamins (β-car-otene,vitamin E,thiamine,riboflavin,vitamin C,niacin,and vitamin A),the calculated values of intakes were found to exceed those obtained via chemical analysis.Conclusion Differences of the two methods of dietary survey were ultimately due to the analysed values were below the calculated ones.So it is necessary to improve methods of food storage and trans-portation in order to obtain adequate nutrition and to improve the health of troops.
