Patients' data security has become very hot topics in health care system. Most of medical staffs in hospitals deal with the information on many patients by computers. It is important to discuss about their awareness of patients' data security same as the information technology. The purpose of this study was to clarify the awareness of patients' data security among nurses and their factors related to such awareness. We conducted the self administered questionnaire (42 items) with 2108 hospital nurses from February through March 2003 and obtained 1645 (78.0%) valid answers. Statistical analysis chisquare test was used. The average age of respondents were 31.0 ± 8.6 (mean ± SD). There were significant differences between the awareness of confidentiality and computer literacy (p<0.001), and confidentiality and availability (p<0.005). The two points are suggested as follows: 1) Education and arrangement of the protocol are essential with a leader aged over 30 years old, with high computer literacy to improve the awareness of data security, 2) it is urgently desired to undertake the reconstruction of the education about the data security.
In Japan, there have been few studies regarding gender differences in obesity in preschool children even though obese children are increasing. This research aims to clarify the gender differences in obesity and BMI (Body Mass Index) distribution among preschool children in Ibaraki Prefecture, Japan. A total of 2408 sets of self-administrated questionnaires answered by the parents were used for statistical analyses. BMI was used to determine the obesity level of children. No significant gender difference was reported in obesity among the subject. As regards cerning to mean BMI, significant gender difference (p<0 .01) was observed only in children of aged 5. The present study showed a possibility of increasing prevalence of obesity with growth and a need for effective prevention efforts in early childhood .
