Based on the new patterns, schools must offer larger amounts of fruits, grains, and proteins/meats to children;the amounts of fluid foods (milk and juice) remained the same. This study examined the effect of the new food pattern on student’s consumption and food cost. Methods: The amounts and cost of foods served and wasted for one week in first grade students attending two elementary schools (n = 812) were measured. One school received the current SBP pattern (control breakfast, average number of students attending breakfast n = 81), the other school’s breakfast reflected the proposed changes (test breakfast, n = 82). To test the hypothesis that the test breakfast leads to significantly increased food cost and food waste compared to the control breakfast, the weekly average amount of the served solid and fluid foods (grams and milliliters) as well as their waste were compared between the two groups using paired student’s t-test in STATA 11 (significance at p-value < 0.05). Results: Data confirmed the hypothesis in that the test breakfast was associated with significantly higher food cost (by approximately $100/week) and solid food waste but there was no change in milk and juice consumption. Conclusions: This exploratory study indicates that a significant portion of the additional foods served to first-graders to improve their nutritional status were not consumed but wasted. Further studies in larger samples and including students from all grades are needed to examine this issue fully.展开更多

This study aimed to discover determinants of sleepiness. <b>Methods:</b> On 2722 questionnaires obtained from pupils in grades 5 - 12 in the Kanto district of Japan, lifestyle habits associated with sleepiness were analyzed using a multivariable logistic regression model. <b>Results:</b> The rate of sleepy pupils (who feel sleepy during class as often and always) increased from elementary school (6.3%) to senior high school (42.4%) via junior high school (17.1%). Higher grade (adjusted odds ratio [OR], 1.28;95% confidence interval [CI], 1.21 - 1.37;p < 0.001), later bedtime before school day (OR, 1.41;CI, 1.26 - 1.57;p < 0.001), longer non-school day screen time (OR, 1.27;CI, 1.16 - 1.40;p < 0.001), poor self-reported academic performance (OR, 1.41;CI, 1.24 - 1.60;p < 0.001), skipping breakfast (OR, 1.18;CI, 1.01 - 1.39;p = 0.041), earlier wake time on school day (OR, 0.84;CI, 0.71 - 0.98;p = 0.026), and higher after-school (OR, 1.03;CI, 1.02 - 1.04;p < 0.001) and physical activities (OR, 1.06;CL, 1.03 - 1.10;p < 0.001) were independently associated with sleepy pupils. <b>Conclusions:</b> To reduce adolescents’ sleepiness in the Kanto district of Japan, we recommend them to have adequate waking time, and to avoid late bedtime, breakfast skipping, excessive screen time, after-school activity, and physical activity. Further prospective studies are needed to confirm involvements of these recommended factors in sleepiness and both physical and mental health outcomes.展开更多
