Abstract
PDF - OBJECTIVES
To examine the screening rate of cervical cancer in women and to find out the predictive factors for participation in cervical cancer screening programs within their life-time and within the last two years. METHODS: The data was based on self-reported questionnaires from 1,613 women whose ages ranged from 26 to 60 years; this survey was performed between December 1999 and January 2000. This study analyzed the predictive factors for participation in cervical cancer screening programs within their life-time and within the last two years. A logistic regression analysis was performed in order to derive the significant variables from the predisposing factors (demographic factor, health promotion behavior, reproductive factor), intervention factors (information channel, relation with medical staff), and proximal factors (attitude, social influence, self-efficacy). All analyses were performed by the PC-SAS 6.12. RESULTS: Our analyses showed that the screening rate for the women who received a cervical cancer screening (Pap smear) more than once within their life-time was 56.1% while those who had received one within the last two years was 34.5%. The significant factors for participation in cervical cancer screening program within their life-time were their income, married age, health promotion score, relation with medical staffs, social influence, and self-efficacy. On the other hand, age, number of pregnancies, menarche age, relation with medical staffs, social influences, and self-efficacy were significant factors for those being screened within the last two years. The predictive power of the logit model within their life-time was 68.8% and that within the last two years was 66.6%. CONCLUSION: The predictive factors for participation in cervical cancer screening program within their life-time are different from those for within the last two years, and that women's relations with medical staffs and social influences were the critical factors impacting on cervical cancer screening rates. -

- OBJECTIVE
To estimate the significance of the Pap smear as a screening tool for cervical cancer. METHODS: A total of 79,840 Pap smear results performed at Pusan Paik Hospital over the 20 year period from 1979 to 1998 were collected and analyzed. RESULTS: The number of Pap smear cases increased markedly during this period, and the results as a whole were classified as consisting of 96.4% normal and benign cytology, 2.2% pre-cancerous cytology, and 1.4% cervical cancer. The relative frequency of cervical cancer decreased from 1.6% in 1979 to 0.7% in 1998. About 64% of the Pap smears were distributed within the age range of 30 to 49 years, and the rate of cervical cancer increased with age, age of marriage and experience of childbirth (p<0.01). The overall agreement of Pap smear results with histologic diagnosis by one histologic degree was 92.7%(1,128/1,217) with 73 overestimated cases and 16 underestimated cases of Pap smear compared to histologic diagnosis. CONCLUSION: This result implies that the Pap smear is an excellent screening tool for cervical cancer with respect to both its scale and validity. Periodic and active Pap smear testing would be helpful for the secondary prevention of cervical cancer. -

- OBJECTIVES
The purpose of this study was to examine the present status of cancer screening recommendations(beginning age, interval, recommended screening methods, etc.) by physicians and analyze the association between physician's characteristics and the content of their recommendations. METHODS: Data were collected from March 1 to April 30 of 1997, and 373 physicians who were from different hospital settings all over Korea were interviewed by telephone about their screening recommendations for stomach, cervical and breast cancer for those who provided cancer screening services. RESULTS: For stomach cancer screening, respondents recommended that cancer screening begin at 40 years of age(57.8%), with a 1 year interval(77.2%), and by gastrofibroscopy (86.2%). For cervical cancer screening, respondents recommended that cancer screening begin at 25 years of age(42.0%), with a 1 year interval(67.8%), and by using a Pap smear(100.0%). For breast cancer screening, respondents recommended that cancer screening begin at 35 years of age(38.7%), with a 1 year interval(57.3%), and by mammography (97.3%). CONCLUSIONS: To establish appropriate cancer screening recommendations for Korea, it may be useful to consider the above results concerning medical care providers. -

Abstract

- A hospital-based case-control study was carried out to investigate the risk factors of uterine cervical cancer in korea. Information on a wide-range of life-styles, which might be related with uterine cervix cancer, has been routinely collected through a dual application of the self-administered questionnaire and the direct interview by a well-trained nurse at the Department of Gynecology, Seoul National University Hospitals since 1992. The number of cervical cancer cases, histologically confirmed at the hospital, were 284. Included were 939 women as controls, who were free of past history of any malignancies. Adjusted odds ratio and 95% confidence limits were based on the unconditional logistic regression model. The multivariate logistic model was constructed under the consideration of biologic characteristics on the natural history of the malignancy. In the multivariate results, the uterine cervical cancer risk was higher in women of shorter height(P(trend) <0.05), less educated spouse (P(trend) < 0.001), multiple marriages(adjusted OR=2,70,95% C.I. 1.64~4.47), ever had a family history (adjusted OR=2.14., 95 % C.I. l.18~3.89), multiparity (P(trend) < 0.001), and early age at first delivery (P(trend) < 0.001). These results strongly suggest that the uterine cervix cancer might be related to the reproductive factors, and probably with sexual behaviour of both women and men in Korea.

- This study was conducted to estimate the prevalence rate of cervical cancer and to investigate its risk factors. 5,417 asymptomatic married women were screened from March, 1984 to December, 1990 in Taegu city. Of 5,417 examinees, 3,817 (70.46%) were normal, 1,542 (28.7%) showed inflammatory change, 51 (0.94%) were dysplasia and 7 (0.13%) were carcinoma in situ or invasive carcinomas. The prevalence of abnormal finding (dysplasia, carcinoma in situ or invasive carcinoma) was 1,070 per 100,000 population. The prevalence of dysplasia was 940 per 100,000 and that of carcinoma in situ or invasive carcinoma was 130 per 100,000. Age-adjusted prevalence rate for abnormal finding adjusted with standard population of Taegu city was estimated to be 850 per 100,000. The prevalence of cervical cancer was significantly increased with age (P<0.05). The prevalence of cervical cancer was significantly decreased with age at marriage and educaitonal level (P<0.05). The history of induced abortion and the number of pregnancies were significantly associated with the prevalence of cervical cancer (P<0.05), whereas, the number of parity was not. Age at marriage was significantly associated with the prevalence of cervical cancer after stratification by age (P<0.05). However, the level of education, parity, induced abortion, number of pregnancies were not significant. Inflammation and human papiloma virus infection were associated with cervical cancer with odds ratio of 13.48(95% confidence interval 7.80~23.40) and 474.29 (95% confidence interval 196.80~1143.10), respectively. In conclusion, for early detection of cervical cancer it should be recommended to perform mass cytological screening. In particular, regular and periodic cytologic screening, starting at age 25, for cervical cancer should be recommended for those women who have frequent cervical inflammation and for those women married before age of 20.

- OBJECTIVE
To evaluate the relationships among sociodemographic characteristics, health behaviors, levels of pros and cons and stages of change in Pap testing for uterine cervical cancer. METHODS: A questionnaire survey was performed on 560 randomly sampled people who were assigned to participate in a Pap testing program by the 'National Cancer Screening Project in 2003' between 25 September and 10 October in Gyeonggi, Korea. Data about the behaviors and intentions of Pap testing, sociodemographic characteristics, health behaviors, and levels of acknowledged benefit (pros) and barrier (cons) for Pap testing was collected. The stages of change were grouped according to behaviors and intentions of Pap testing as passive, active, and relapse. RESULTS: Logistic analysis between the passive and active groups showed that city dwellers, 'high' and 'middle' groups in terms of the individual's health belief, those who had undergone a health examination within the past 2 years, and those who had undergone hormone replacement therapy had a higher odds ratios to be in the active group. As the 'benefit' scores increased and the 'Unnecessity' scores decreased, the probabilities to be in the active group increased. According to the logistic analysis results between the active and relapse groups, those who were 60 years or older, members of the National Heath Insurance, and those who had not undergone a health examination within the past 2 years had a higher odds ratio to be in the relapse group. The 'Benefit' scores were not significant in this relationship. The probabilities of being in the relapse group increased as the 'Unnecessity' and 'Shamefulness' scores increased. CONCLUSIONS: In conclusion, health planners should inform women in the passive group of the benefits and necessity of Pap testing. It would be better to reduce the barriers to the active group of undergoing Pap smear. This study might be a useful guide for future planning of Pap testing program. -

Abstract

- OBJECTIONS: Cervical cancer is the second most frequent cancer among women in Busan. The Pap smear test could have a significant effect on detecting cervical cancer, and enhancing their rate of use is an important strategy for reducing the incidence and mortality of cervical cancer. This study aimed to evaluate the factors associated with the past use of the Pap smear test in Korean women. METHODS: A population-based survey was carried out in Busan between November 1999 and March 2000. 1, 673 participants were randomly selected from 2, 684 women in Busan, using a 2-stage cluster sampling method, and interviewed in their homes. Their socio-demographic characteristics, smoking, drinking, familial cancer history, Pap smear screening history, reproductive and menstrual factors, sexual habits and use of contraceptive methods data were collected by a trained interviewer using a questionnaire. The use of the screening test was defined by a self-report from the participants on how many times they had had a Pap smear test in their lifetime, and when they had received their latest examination. RESULTS: Of the 1, 673 respondents (62.3% response rate), 57.6% had had a Pap smear test during her life (mean number, 2.3). Among the health examination participants (1, 064), 961 (90.3%) reported having sexual experience and 70.9% of these had had a Pap smear test. In a multiple logistic regression analysis, statistically significant relationships were observed for age groups and the Pap smear test rate (odds ratio, OR for 35-44 years=2.45; OR for 45-54 years=3.41; OR for 55 years=2.60; reference, under 34 years). The married or cohabiting women were more likely to have used the Pap smear test than those separated or widowed (OR=1.73). Among the reproductive behavioral measures, the number of births (OR for 3 births=4.22; OR for 2 births=3.95; OR for 1 births=3.38; reference, 0 births) and husband's extra-marital affairs (OR=1.50) were associated with the rates of use of Pap smear tests. CONCLUSION: It appears that the most important contributing factors to cervical cancer screening were age, marital status and number of births. A positive association was also observed for the husband's extra-marital affairs. This study enabled us to systematically assess the relationship between Pap smear rates and risk factors for cervical cancer. It is hoped that this study will make a significant contribution to the accumulating scientific evidence on the identification of factors associated with cervical cancer screening in Korea.
