Abstract
Breast and cervical cancer cases are rising among service and industrial women workers in Vietnam. We conducted a cross-sectional study among 287 workers in three factories in Hanoi and Bac Ninh from July to September 2018 to describe the knowledge of these cancers among industrial workers in Northern Vietnam using a structured questionnaire. Factors associated with knowledge of breast and cervical cancer were identified using generalized linear models (GLM). In our study, approximately one-third of participants believed breast cancer was caused by the lack of breastfeeding, exposure to pollution, and chemicals. Less than 50% knew about sexually transmitted infections that can cause cervical cancer or were aware of a vaccine for cervical cancer. Having one sexual partner within the last year was positively associated with having a higher score of knowledge for both diseases. Receiving a medical checkup within the last 12 months and seeking health information via the internet were related to greater breast cancer knowledge. Targeted education campaigns are needed to ensure proper knowledge and improve awareness of breast cancer and cervical cancer among industrial workers.Entities:
