| 摘要: | Research background: Detection of breast cancer in early stage can improve the quality of treatment and reduce the mortality rate. Knowledge and perceived health beliefs related to breast cancer are known as the factors influence on breast cancer screening practice. This study was the first one to investigate the concepts of knowledge, perceived health beliefs related to breast cancer screening based on Health Belief Model (HBM) with mammography use among Vietnamese women which clarified into Vietnamese in Taiwan group and Vietnamese women in Vietnam group.
Aims: This study aims to compare the rate of mammography use, knowledge and perceived health beliefs related to breast cancer screening based on HBM between Vietnamese women in Taiwan and Vietnamese women in Vietnam, meanwhile, explore the relationship between background factors and screening practice, the association between knowledge or perceived health beliefs related-breast cancer and mammography use in each group, Vietnamese women in Taiwan or Vietnamese women in Vietnam.
Methods: A cross-sectional survey was carried out into two countries, Taiwan and Vietnam between June and August 2018. The interest of population in this study was Vietnamese women aged 40 and older who are legal residents in Taiwan and Vietnam. Participants were interviewed by phone of mainly 47 items, including demographic and socioeconomic characteristics, knowledge of breast cancer regarding risk factors and symptoms, and components of the Health Belief Model: perceived susceptibility, perceived seriousness, perceived benefits, and perceived barriers related to breast cancer screening (mammography). Descriptive statistics were used to describe the demographic characteristics of two groups, participants in Taiwan and Vietnam. Man-Whitney U tests were used to compare the mean scores of knowledge and perceived health beliefs between two Vietnamese women groups. Chi-square tests were used to compare mammography use between two Vietnamese participants groups and explore the relationship background factors and mammography practice in each Vietnamese women group. Bivariate analysis was used to explore the association of knowledge and perceived health beliefs related to breast cancer screening with mammography use in each group, Vietnamese women in Taiwan or Vietnamese women in Vietnam.
Results: The eligible participants in this study totally are 140, including 70 participants in Taiwan and 70 participants in Vietnam. The median age of participants was 45 years (range, 40-66 years). Vietnamese women in Vietnam group were significantly older than Vietnamese women in Taiwan group. The participants in Vietnam group were showed lower screening rate with a statistical significance compared with the participants in Taiwan (p=0.001). Through analysis to identify factors influence on the participation of mammography practice in each group, the findings revealed that age, menstrual status, and length of residence were found significantly affected to mammography using among Vietnamese women in Taiwan group (p<0.0001, p=0.002, and p=0.003, respectively) while Vietnamese women in Vietnam group did not show any significant association between demographic characteristics and mammography practice. The relationship between knowledge or perceive health beliefs related-breast cancer concepts and mammography practice in previous studies were found not consistent in this study.
Conclusion: The results suggest to establish and implement national breast cancer screening program in Vietnam. Also, recommending to nurses in Vietnam design an appropriate-aged health education programs of breast cancer screening based on HBM to women. |
