Breast self-examination (BSE) is a simple, feasible, and suitable method for breast cancer screening in low-middle setting countries. The aim of this study was to assess the knowledge and practice of BSE among female textile workers in Vietnam. A cross-sectional study was conducted among 1036 female workers, aged 43.9 ± 3.1 years old, who were working in 4 textile enterprises in Hanoi and Ho Chi Minh City, in 2016. Overall, 22.7% of participants showed sufficient knowledge on BSE; 15.2% performed monthly BSE; and 7.7% completely performed all 5 steps of BSE. The prevalence of insufficient BSE knowledge was higher among participants with low level of education (odds ratio [OR]: 1.71; 95% confidence interval [CI]: 1.22-2.39, below vs above secondary school), and those whose husbands were farmers or workers (OR: 1.76; 95% CI: 1.27-2.45, compared to other sectors). This prevalence was, however, negatively associated with receiving information on BSE (OR: 0.16; 95% CI: 0.11-0.23, yes vs no). The prevalence of insufficient BSE practice was also higher among females with husbands who were farmers or workers (OR: 1.67; 95% CI: 1.15-2.43, compared to other sectors). In contrast, it was much lower among participants who had history of breast-related diseases (OR: 0.46; 95% CI: 0.24-0.88, yes vs no), received BSE information (OR: 0.13; 95% CI: 0.08-0.19, yes vs no), and had sufficient overall BSE knowledge (OR: 0.09; 95% CI: 0.06-0.13, yes vs no), compared to those who did not. There was a low prevalence of sufficient BSE knowledge (22.7%) and practice (15.8%) among female textile workers in Hanoi and Ho Chi Minh City. Low level of education and not being provided BSE information were associated with insufficient BSE knowledge and practice among Vietnamese female textile workers. Health education programs are essential to encourage and improve women's knowledge and practice of BSE.
