卫生学校学生营养状况调查 总被引:1,自引:0,他引:1
[目的]了解卫校学生营养状况,为制定相应措施提供依据。[方法]按照《中国卫生监督统计报表学校卫生情况年报表技术规范》要求,对某卫校住校学生进行身高、体重测量。按照《2000年全国学生体质调研报告》确定学生营养状况。[结果]男学生肥胖高于女学生,营养不良低于女学生。不同年级女学生营养不良、肥胖检出率差异有统计学意义。城市和农村男学生营养不良、肥胖检出率差异无统计学意义;城市和农村女学生营养不良检出率差异有统计学意义。不同膳食消费水平女学生营养不良检出率差异有统计学意义。[结论]卫校学生营养问题严重,对年龄较小、自我生活能力较差、肩负着对他人进行营养保健指导责任的卫校学生,及早进行营养教育和干预很有必要。 相似文献

The aim of the present study was to investigate current problems of snacking behavior and their relationship to stress coping among 1,486 fourth through ninth grade students from 10 elementary schools and six junior high schools. An anonymous self-completed questionnaire was utilized which included items about 1) selection of snack foods, which were classified into healthy, popular, complementary and western-style snacks, 2) problems of snacking behavior, which included external and emotional eating scores, and 3) stress coping scale. The stress coping scale contained two sub-scales; problem-focused and emotion-focused coping. The results were as follows: 1) Students who frequently went without breakfast did not select healthy foods, i.e., fruits and dairy products, but popular snacks, i.e., potato chips, pop corn and sweet beverage. 2) Both external and emotional eating scores increased by age in girls but was not apparent in boys. 3) Students who preferred either western-style or popular snacks showed higher score of external and emotional eating. 4) The score of problem-focused coping was positively correlated with preference for health snacks, but emotion-focused coping was positively correlated with external and emotional eating scores. The close relationship between snack food selection and problematic aspects of eating behavior suggests that modification of eating behavior is necessary to develop healthy snack habits in early adolescents. Also, it is interesting that snacking behavior is closely related to stress coping, which suggested the behavioral intervention for healthy eating habit should be included in development of stress-coping skills against various kinds of demands in life. 相似文献

Nutrient intakes and snacking frequency in female students 总被引:1,自引:0,他引:1
Background: Snacking can have the negative image of being detrimental to the diet, because snack foods are commonly thought of as providing only 'empty calories'—high in energy but low in micronutrients. This observational study looked at the nutrient density of snacks and meals, and at the effect of eating frequency on mean daily nutrient intakes in 44 female students (aged 17–26 years). Methods: Baseline dietary data from an existing intervention study were re-analysed. Eating occasions, taken from 7-day weighed food diaries, were classified as meals or snacks by time of day, and the composition of meals and snacks compared. Subjects were divided into tertiles by eating frequency and their nutrient intakes compared. Results: As eating frequency increased, the number of snacks and the number of different snack items in the diet increased, while the number of meals remained constant. Snacks, overall, were significantly lower in percentage non-alcohol energy from fat and higher in percentage non-alcohol energy from carbohydrate. Snacks had lower nutrient densities than meals for non-starch polysaccharide (NSP), minerals and vitamins except vitamin C. However, there were no significant differences between the top and bottom tertiles of snacking frequency for overall percentage energy from fat, protein or carbohydrate, or intakes of micro-nutrients. The top tertile tended to be leaner and have higher energy intakes than infrequent eaters (not significant). There was a significant negative correlation between eating frequency and body mass index (BMI). Conclusions: It is concluded that snacking per se did not compromise diet quality in this group, and that those with a high snacking frequency were eating more in general and choosing a wider variety of foods, resulting in a balanced intake of nutrients. 相似文献

Meal and snack patterns of 114 male and 111 female adolescents in a southern Appalachian state were examined from 24-hour food records kept on a school day. Breakfast was skipped by 34% of the respondents, and 27% either skipped lunch or ate a snack-type lunch. The evening meal and snacks, each of which contributed about one-third of the daily energy intake, were eaten by 94% and 89%, respectively. Girls' mean intakes of vitamin A, calcium, and iron were low at all eating occasions throughout the day. Boys' mean intakes of iron were low at breakfast, lunch, and snacks; their vitamin A intakes were low at lunch and snacks. Adolescents who prepared their own breakfasts consumed less energy, protein, fat, and niacin at that meal than did adolescents who ate breakfasts prepared by their mothers. However, adolescent-prepared breakfasts were higher in nutrient density for calcium, riboflavin, and thiamin. Evening meals prepared by adolescents were similar in total nutrient content to meals prepared by their mothers but lower in nutrient density for iron and thiamin. Evening meals prepared by adolescents were more likely to include a sandwich and less likely to include a vegetable than were meals prepared by mothers. 相似文献

BACKGROUND: Eating behaviors developed during adolescence can have immediate health implications and influence future chronic disease risk. The objectives of this study were to determine and compare the distribution of energy and nutrient intakes among meals and snacks, and relate eating occasion frequency to body mass index (BMI) of adolescent males. METHODS: Healthy adolescent males (n = 180) completed 3-day food records. Following analysis for energy and nutrient intakes, 3-day averages and frequencies were computed for all meals and snacks. RESULTS: Dinner was the largest contributor of energy, macronutrients, cholesterol, dietary fiber, and sodium, whereas both dinner and breakfast were the largest contributors of calcium and iron. On average, subjects consumed 1.63 snacks/day, with 77% consuming > or = 1 snack/day. BMI was significantly greater and energy intake was significantly lower in subjects having < or = 3 eating occasions/day relative to 4 or > or = 6 eating occasions/day. The 26% of subjects classified as inconsistent breakfast consumers had significantly higher BMIs and lower iron intakes relative to consistent breakfast consumers. CONCLUSIONS: This study provides valuable information regarding eating occasion frequency and contribution of meals and snacks to energy and nutrient intakes in adolescent males. Such information could be used to improve nutrition education programs for adolescents aimed at chronic disease prevention. 相似文献

ObjectiveTo evaluate the association between specific dietary habits and body fatness in Spanish adolescents, and to analyze the role of leisure-time physical activity (LTPA) in this association.MethodsIn this cross-sectional study, 1,978 adolescents (1,017 girls) aged 13.0–18.5 years from the AVENA (Alimentación y Valoración del Estado Nutricional en Adolescentes) study were included. Particular dietary habits (breakfast, mid-morning snack, lunch, afternoon snack, dinner, and nighttime snack, as well as time spent eating, number of meals, consumption of soft drinks, and ready-to-eat foods) and LTPA were self-reported and analyzed as dichotomic variables (yes/no). The sum of six skinfold thicknesses and waist circumference (WC) values were the main body fatness variables.ResultSkinfolds and WC values were lower in adolescents who reported consumption of mid-morning snack, afternoon snack, more than four meals per day, and an adequate speed of eating, independently of participation in LTPA. Moreover, a beneficial influence of breakfast consumption on skinfolds and WC values was observed in those adolescent boys who did not participate in LTPA (p for interactions = .044 and .040, respectively).ConclusionsIn Spanish adolescents, certain healthy dietary habits (i.e., mid-morning snack, afternoon snack, > 4 meals per day, adequate eating speed) are associated with lower body fatness, independently of engaging in LTPA. In addition, among boys with non-LTPA, those who skipped breakfast showed the highest body fatness values, indicating a beneficial influence of daily breakfast on body fat in this particular group. 相似文献
