The purpose of this study was to examine the breastfeeding knowledge of pregnant working women and explore factors
that affected their knowledge. This Turkish study included 260 healthy, working women in the last trimester of pregnancy.
Two separate questionnaires developed by the researcher were used to collect data. The average knowledge score of
pregnant women respondents for all questions were 6.03 ± 2.99 (range: 0 to 14). Pregnant women had the least knowledge
about duration of expressing breast milk (21.9%) and safe storage conditions for breast milk (27.2%). They knew
the most about methods to express breast milk (87.3%) and features of containers used to store expressed milk (80%).
Study results indicated that working pregnant women need better prenatal education to continue safe breastfeeding after
returning to work. Occupational health nurses should inform working pregnant women about expression and storage of
breast milk during prenatal education.
