Abstract
Cancer is a common health problem worldwide. Early cancer education for adolescents and young adults (AYAs) is important for the prevention or early detection of cancer. In this questionnaire-based cross-sectional study, we examined the cancer awareness among parents of AYAs. Japanese adults with junior or senior high school children were included in this study. The cancer awareness measure (CAM) was used to assess cancer awareness, and the survey was conducted in December 2021. Warning signs, barriers to seeking help, and risk factors were surveyed using an online anonymous questionnaire. In addition, personal information, the presence of other cancer survivors, attendance at cancer seminars, conversations with children about cancer, interest in cancer education for children, and previous cancer screening were surveyed. A t-test or Spearman correlation coefficient was used to compare the total CAM scores for the individual factors. The relationship between cancer-screening behavior and individual factors was analyzed using the χ2 test. In addition, multiple regression analysis or logistic regression analysis was used to identify the factors influencing cancer awareness or cancer-screening behavior. Responses were obtained from the 612 participants. The mean CAM score was 3.7 for cancer warning signs, 4.3 for barriers to seeking help, and 6.5 for risk factors. Cancer warning signs were associated with gender and the presence of a spouse, family member, or friend who had experienced cancer. Barriers to seeking help were associated with age, gender, and education, while risk factors were associated with gender, education, and conversations about cancer with children. Moreover, these scores were associated with each cancer screening behavior. Cancer awareness among Japanese adults with AYAs was influenced by gender, academic background, occupation, the presence of cancer survivors around them, and whether they had conversations about cancer with their children, as well as their cancer screening behavior.
