Background: Health literacy serves as a major barrier to effective preventive health behaviors, such as cancer
screening, and this relationship has not been studied among insured women in Japan. We examined the relationship
between health literacy and adherence to recommendations to undergo cancer screening, and health-related behaviors,
among Japanese women who were insured by a health insurance society. Methods: We conducted a cross-sectional
observation study of 670 insured Japanese women. For this, we used a self-administered questionnaire to assess
environments, self-rated health status, cancer screening behavior, health-related behaviors (dietary behavior, exercise
frequency, alcohol consumption and smoking behavior), and health literacy. Results: Among the participants, 206
completed the questionnaire (response rate, 30.7%). Fifty-seven had undergone breast and/or cervical cancer screening.
The mean health literacy score was 3.44 (standard deviation = 0.68). In logistic regression models adjusted for age,
self-rated economic status, and having a primary care physician, there was no statistically significant relationship between
health literacy and adherence to recommendations to undergo cancer screening, and health-related behaviors. However,
age and having a primary care physician were significantly associated with cancer screening and health-related behaviors.
Health literacy was not found significantly associated with effective preventive health behaviors. Conclusions: The
present study found no statistically significant relationship between health literacy and adherence to recommendations
to undergo cancer screening and health-related behaviors. Rather, cancer screening and health-related behaviors were
found related to medical support from physicians and those their own age. Further study is needed for exploring these
associations among insured women in Japan.
