RESUMEN
【Objective】 To explore the status quo and influencing factors of knowledge, attitude and practice of voluntary blood donation among undergraduates in Beijing. 【Methods】 A questionnaire was designed on the basis of literature, using the method of convenience sampling to survey the undergraduates from 39 universities in Beijing. The t-test, analysis of variance and χ2 test were used to compare the differences in knowledge, attitude and practice of voluntary blood donation among different groups, and logistic regression model was performed to analyze the influencing factors. 【Results】 A total of 1 075 valid questionnaires were collected from undergraduates of 39 universities in Beijing. The results showed that the proportion of the participants who had good knowledge about voluntary blood donation was 69.21% (744/1 075). No statistically significant difference was noticed on the scores of voluntary blood donation knowledge between males and females (P>0.05). The scores of voluntary blood donation knowledge of medical students were higher than those of other subjects (P<0.05). The scores of voluntary blood donation knowledge of juniors and above were higher than those of lower grades (P<0.05). The rate of undergraduates participating voluntary blood donation in Beijing was 30.98% (333/1 075). A total of 67.26% (723/1 075) of students had donation intention, 9.49% (102/1 075) didn’t and 23.25% (250/1 075) were not sure. No statistically significant differences in blood donation intention were observed among undergraduates by genders and grades (P>0.05). The rate of medical students’ intention to donate blood was higher than that of other subjects (P<0.05). 【Conclusion】 The rate of voluntary blood donation among undergraduates in Beijing was above the middle level compared with other regions in China, but the practice of voluntary blood donation is far away from the intention. Therefore, it’s necessary to improve the level of knowledge, attitude and practice of undergraduates, especially non-medical college students, so as to improve the rate of voluntary blood donation among the undergraduates in Beijing.
RESUMEN
Objective To explore the utilization and effectiveness of ultrasound screening for neural tube defects (NTDs),so that to provide scientific evidences for the secondary prevention of NTDs.MethodsFour hundred and fifty-nine women who delivered or gestated NTDs babies or fetuses were randomly selected from Shandong Province and Shanxi Province,and the related information was collected with structured questionnaire by trained interviewers.Results Of the 459 cases,the ultrasonography utilization rate was 98.7%,and 6 cases (1.3%) never took examinations by ultrasonography during the whole pregnancy period.The total diagnosis rate of ultrasound screening for NTDs was 85.9%,and those of anencephalus,spina bifida and encephalocele were 96.4%,79.6% and 73.8% respectively (P0.05).Conclusions The detection rates of NTDs and the subtypes by ultrasonography are low at different pregnant periods and in different medical institutions.It is important to increase the utilization rate of ultrasound screening by pregnant women and improve the NTDs diagnostic level of primary health care institutions,so that to improve the efficacy of secondary prevention strategy for NTDs in China.
