  • Objectives: The purposes of this study were to propose a screening schedule for the early detection of breast cancer among Korean women, as based on the statistical model, and to compare the efficacy of the proposed screening schedule with the current recommendations. Methods: The development of the screening schedule for breast cancer closely followed the work of Lee and Zelen (1998). We calculated the age-specific breast cancer incidence rate from the Korea Central Cancer Registry (2003), and then we estimated the scheduling of periodic examinations for the early detection of breast cancer, using mammography, and based on the threshold method. The efficacy of the derived screening schedule was evaluated by the schedule sensitivity. Results: For estimating the screening schedule threshold method, we set the threshold value as the probability of being in the preclinical stage at age 35, the sensitivity of mammography as 0.9 and the mean sojourn time in the preclinical stage as 4 years. This method generated 14 examinations within the age interval [40, 69] of 40.0, 41.3, 42.7, 44.1, 45.4, 46.7, 48.0, 49.3, 51.0, 53.2, 55.3, 57.1, 59.0 and 63.6 years, and the schedule sensitivity was 75.4%. The proposed screening schedule detected 85.2% (74.5/87.4) of the cases that could have been detected by annual screening, but it required only about 48.7% (14.0/30.0) of the total number of examinations. We also examined the threshold screening schedules for a range of sensitivities of mammography and the mean sojourn time in the preclinical stage. Conclusions: The proposed screening schedule for breast cancer with using the threshold method will be helpful to provide guidelines for a public health program for choosing an effective screening schedule for breast cancer among Korean women.

  • Objectives: We examined the agreement between the Autism Diagnostic Observation Schedule (ADOS) and the Childhood Autism Rating Scale (CARS) in the diagnosis of autism spectrum disorder. Methods: The ADOS and CARS scores of 78 children were retrospectively collected from a chart review. A correlation analysis was performed to examine the concurrent validity between the two measures. Using the receiver operating characteristic (ROC) curve, we determined the optimal cut-off score of the CARS for identifying autism spectrum disorder. Results: The CARS score was significantly correlated with the ADOS score (r=0.808, p<0.001). Taking ADOS as the ideal standard, the optimal cut-off scores of CARS for identifying autism and autism spectrum were 30 and 24.5, respectively. Conclusion: We determined the optimal cut-off scores of CARS for screening and diagnosing autism spectrum disorder.

  • Objectives: The aim of this study was to determine the distribution of stages of adoption in stomach cancer screening and elucidate differences among stages. Methods: A randomly selected sample of 712 Korean males and females aged 40 years or over were interviewed. Stomach cancer screening intention and behavior, sociodemographic characteristics, beliefs, self-efficacy and reinforcing characteristics were assessed. Results: The majority of participants were not on-schedule screening(unaware 3.2%, unengaged 20.8%, deciding about acting 24.0%, decided not to act 9.6%, decided to act 14.5%, acting 9.7%, maintenance 18.3%). Perceived susceptibility, perceived barriers, self-efficacy, other cancer screening experiences were significantly associated with higher compared to lower Precaution Adoption Process Model(PAPM) stages. Conclusions: This study appears to be applicable of the Precaution Adoption Process Model to understanding stomach cancer screening behavior. Our results suggest that it is needed to develop the tailored message for adherence of stomach cancer screening.

  • The human papilloma virus (HPV) is the main aetiological agent for cervical cancer, one of the most frequent cancers observed in women throughout the world. There are effective programs for reducing the incidence of cervical cancer with HPV vaccination. The objective of this study was to discuss the applicability of the HPV vaccination and the role of nurses in prevention of cervical cancer. Use of bivalent and quadrivalent vaccines has been initiated against the types of HPV which are the primary cause of cancer. The quadrivalent HPV vaccination has entered into the routine vaccination schedule in many European countries for use in children and adolescents between 9-15 years of age and for women between 16-26 years of age, whereas it has been proposed that the bivalent vaccination should be given to girls between 9-18 years of age. While cervical cancer is among the cancers that can be prevented, it is essential to continue screening tests while introducing vaccination in a systematic manner for protection. On this subject, among the most important roles of nurses is to implement the screening programs by fulfilling the caregiving, training and consultancy roles for the society and especially, for high risk groups and to increase the awareness of the people.

  • Background: It has been proven that an individuals health behavior is determined through a series of processes. This study aimed to assess the stages of adoption of breast cancer screening, and to identify the factors relating to progress through these stages. Materials and Methods: There were 202 female participants aged 20-59 years who were living in Chungbuk, South Korea. They were informed of the study purpose and agreed to participate. Data were collected from October 2010 to January 2011 by assessing the breast cancer screening stage, health beliefs, socio-demographic factors, and other facilitating factors. The participant current stage of adoption of breast cancer screening was classified using the Precaution Adoption Process Model (PAPM), and the various PAPM stages were compared with each other to identify factors likely to determine progress between stages. The data were analyzed using the ${\chi}^2$-test, ANOVA, Duncan test, and multiple logistic regression. Results: Approximately half of all participants were not on-schedule for breast self-examination and mammography (unaware, 9.4% and 11.4%, unengaged, 8.4% and 5.0%, undecided, 20.3% and 17.8%, decided not to act, 1.5% and 1.0%, decided to act, 13.4% and 15.3%, respectively). The factors likely to determine the progress from one stage to another were age, marital status, exposure to media information about breast cancer, self-efficacy, and perceived severity. Conclusions: These results suggest that it is necessary to develop a tailored message for breast cancer screening behavior.

  • Objectives : Dementia has rapidly increased with the prolongation of life expectancy and aging in Korea. This study was conducted to estimate the prevalence of, and find related factors for, dementia in an urban elderly population, using a newly developed screening method. Methods : Seven hundred and six people, aged over 65 years-old, in Dong district of Gwangju, Korea, were recruited using stratified cluster sampling, and completed Korean version of Geriatric Mental State Schedule B3 (GMS B3-K), the Korean version of the Community Screening Interview for Dementia (CSID-K) and modified 10 word list-learning from the Consortium to Establish a Registry of Alzheimer's Disease (CERAD). Dementia was diagnosed by an algorithm derived from all three of these measures. Results : The crude and age adjusted prevalence rates of dementia were 13.0 and 11.5%, respectively. Age, education, marital status and a history of cerebrovascular disease were identified as factors related with dementia. Conclusions : The new instrument, using the GMS B3-K, CSID-K and modified 10 word list-learning from the CERAD, was considered effective as a community screening and diagnostic tool for dementia. The results of this study can also be used to develop a community-based prevention and management system for dementia in the future.
