Predictors of breast and cervical screening in Vietnamese women in Harris County, Houston, Texas

The Vietnamese are a quickly growing, important part of the Texas population. Breast cancer is known to have different biologic characteristics in Vietnamese women. In order to develop appropriate intervention and screening strategies, we conducted a study of barriers to cervical and breast screening in Vietnamese women in Harris County, Tex. Our objective was to characterize the demographic factors, beliefs, and barriers to cervical and breast cancer screening in our study population and test the effect of these on Papanicolaou test, breast self-examination (BSE), medical breast examination (MBE), and mammography use. The Health Belief Model Scales for Measuring Beliefs Related to Breast Cancer (Champion VL, Nursing Research 1993;42:139-143) was the framework used to assess attitudes regarding risk of breast cancer and to design a component assessing risk of cervical cancer. The questionnaire addressed susceptibility, seriousness, benefits, barriers, and health about screening for breast and cervical cancer. It was translated into Vietnamese and back-translated into English prior to use. The questionnaire was mailed to Harris County residents. Those returned were entered into a database. The data were analyzed for validity using Chronbach's alpha. Simple descriptive analyses and nominal logistic regression identified predictors of Papanicolaou test, BSE, MBE, and mammography use. Twelve hundred surveys were mailed out to Vietnamese women using the telephone directory and the church directories in Harris County; 209 were returned and entered into the database. Of the respondents, 67% had ever received a Papanicolaou test; of these, 89% had received a Papanicolaou test within the past year; 55% of respondents had performed a BSE, 45% of patients received an MBE, and 45% of respondents had ever received a mammogram (15% of respondents had a mammogram during the previous year). The most significant predictors of Papanicolaou test, BSE, MBE, and mammography use were marital status (being married), high educational level, lack of barriers, a family history of the cancer, older age, and increased perception of seriousness. Compared to other studies of Vietnamese women, the women in Texas are among the highest users of the Papanicolaou test, BSE, MBE, and mammography. Barriers and incentives to breast and cervical screening were similar to those in other studies.
