Methods: All patients (n = 104) who went to the department of gastroenterology of Hua Dong Hospital were recruited. Dietary behavior of patients was investigated by a questionnaire self-designed while the nutritional status was evaluated using the Patient-generated Subjective Global Assessment (PG-SGA). Results: Among 104 cases with IBD, the numbers of well dietary belief were 58 cases (55.8%) and the poor were 46 cases (45.2%). The good eating habits were 33 cases (31.7%), the general were 25 cases (24.0%) and the poor were 46 (44.2%). The adequate intakes of carbohydrate, protein and fat were separately 36 cases (34.6%), 25 cases (24.0%) and 33 cases (31.7%) while the inadequate intakes were separately 68 cases (65.4%), 79 cases (76.0%) and 71 cases (68.3%). Sex, culture degree and duration were influence factors of the dietary belief (P < 0.05). Conclusion: The problems in dietary behavior are not optimistic. Most patients with IBD are with poor dietary belief and eating habits while the intake of carbohydrate, protein and fat is insufficient although the choice of food is reasonable. And majority of patients were combined with malnutrition. Education of the dietary knowledge about IBD should be strengthened, especially for patients who are female, short-term duration and lower culture degree.展开更多

Methods: A 3-day (2 weekdays and 1 weekend day) 24-hour (24-HRs) dietary recall was conducted to record details of participants’ food consumption. One-way analysis of variance (ANOVA) was applied to examine the influence of the identified demographic variables (including BMI, gender, major, family monthly income, and place of household registration) on the 8 food groups’ consumption. We analyzed the effect of the various demographic variables on sodium intake by the student’s t-test. The questionnaire, International Physical Activity Questionnaire (IPAQ)-Short Form, was utilized to assess participants’ physical activity (PA) level. The Wilcoxon-Mann-Whitney was applied to analyze participants’ physical activity. Results: Our research indicated participants consumed much fewer fruits and vegetables and excessive meats on average for both males and females regarding NCDs prevention. Conclusion: Participants’ dietary intake did not comply with the Chinese Dietary Guide-lines recommendation for chronic diseases prevention. Nutrition knowledge and health education are needed for college students. .展开更多

The extraction of the oils was performed by hydrodistillation (2 h) using a modified Clevenger apparatus and the oils were subsequently subjected to analysis by gas chromatography/flame ionization detector (CG/FID) and gas chromatography/mass spectrometry (GC-MS). A completely randomized design with five treatments and four replications was adopted. The bean plants were sprayed with solutions of the oils dissolved in aqueous Tween 80 solutions at concentrations of 0 (water + Tween 80), 0.5%, 1.0%, 1.5% and 2.0% and then furnished to the insects with no choice available. Seven days after the application, the percentage of leaves with injury, degree of defoliation, the preference index for consumption and the percent of mortality of insects were evaluated. Neither of the essential oils caused a reduction in foliar injury, but antifeeding activity was observed, causing reduced feeding and increasing the mortality of adult D. speciosa insects.展开更多

文摘The coronavirus disease 2019(COVID-19)pandemic led to sudden extreme changes in lifestyle,potentially causing adverse changes in physical activity,sedentary behavior,and dietary habits.The objective of the study was to investigate the effects of COVID-19 quarantine on physical activity,dietary habits,and food insecurity among college students who were impacted by the quarantine periods and campus closures.The findings of the study will provide preliminary evidence on dietary,physical activity,and sedentary behavior changes induced by the pandemic among college students.Participants(n=403)completed a cross-sectional self-report online questionnaire,evaluating the physical activity,sedentary behavior,and dietary behaviors before-and during-COVID-19 campus closures(March–May 2020).Sociodemographic and descriptive information was also obtained from each participant.Wilcoxon signed-rank test was used to assess changes in physical activity,sedentary behavior,and dietary habits.McNemar's test was used to compare food insecurity changes.Data were presented as median and interquartile range.A total of 291 participants who met the inclusion criteria were enrolled in the study(college-aged,18–24 years).Physical activity decreased at vigorous(2 days/week to 1 day/week,p<0.001),moderate(4 days/week to 1 day/week,p<0.001),and light(4 days/week to 2 days/week,p<0.001)intensity levels,while sedentary behavior increased(4 h/day to 7 h/day,p<0.001)from pre-to during-COVID-19 quarantine period.Frequencies of meals at home and alcohol consumption increased(Z=-3.911 and Z=-4.022,p<0.001),while frequency of fruit consumption decreased(Z=-2.116,p<0.001)from pre-to during-COVID-19 quarantine period.Daily alcohol intake also increased during COVID-19 quarantine period(Z=-4.442,p<0.001).Lastly,the percentage of individuals reporting food insecurity significantly increased during COVID-19 quarantine(p<0.001).College-aged students in quarantine significantly decreased physical activity participation and increased sedentary behavior.Changes in dietary habits were observed,including increased meals at home,alcohol con-sumption,and decreased fruit consumption.Food insecurity also doubled among college-aged students during quarantine.Public health strategies to attenuate these changes in lifestyle habits should be implemented during a global pandemic.
文摘Background:Children from underrepresented populations exhibit low levels of physical activity(PA),diet quality,and health-related quality of life(QoL),but participation in extracurricular activities may positively impact these health outcomes.Purpose:To examine differences in PA,dietary behavior,and QoL in underrepresented children by extracurricular activity dose(0,1,≥2)and type(sports,dance/martial arts,art/music).Methods:Children(N=754;Grades 4–6)completed the Physical Activity Questionnaire for Children,KidsScreen-27(QoL),and the School Physical Activity and Nutrition Survey and self-reported extracurricular activity participation.One-way MANOVA tests were used in this analysis.Results:Individuals participating in 1 and≥2 activities(p<0.001),sport/dance/martial arts(p<0.001),and art/music(p=0.029)had higher PA than non-participants.Those participating in≥2 activities reported higher fruit intake compared to 1 activity and non-participants(p=0.009;p<0.001,respectively).Participants with≥2 activities reported higher parent-and peer-related QoL compared to non-participants(p=0.001;p=0.025,respectively).Conclusions:Extracurricular activity participation was positively associated with health behaviors in underrepresented children.Schools may be encouraged to allocate some of their resources to extracurricular activity programing.
