Fathers’ participation in the HPV vaccination decision-making process doesn’t increase parents’ intention to make daughters get the vaccine

Introduction The HPV vaccination rate in Japan has been dismally low. Our previous survey work found that mothers in Japan, who have a strong influence over their daughters, often are receptive to the fathers’ participation in the family’s decision-making process about getting their daughter HPV vaccinated. Methods We conducted a survey to investigate the nature of the influence of fathers’ participation on the mother’s decision-making process. From an internet survey panel, we selected a pool of 1,499 eligible mothers who had 12–18 years old daughters. The mothers were randomized into three Groups. To the mothers in Group A, we gave an educational leaflet regarding HPV vaccination and a second leaflet which recommended that they talk with their husbands about the vaccination. To Group B, we gave only the educational leaflet. No leaflets were sent to Group C. A structured survey questionnaire was then distributed through the internet to the mothers. Results In Groups A, B, and C, their intention to have their daughter receive the HPV vaccine was 21.6%, 20.7% and 8.2%, respectively. The percent of Group A mothers who thought their husband’s opinion was important for when they made the decision was significantly higher (70%) than in Group B (56.6%) or Group C (47.1%). Conclusions The fathers’ participation in the mothers’ decision-making does not increase the likelihood of HPV vaccination for their daughters. On the other hand, the educational leaflet proved to be effective for this cause

Changing attitudes in Japan toward HPV vaccination: a 5-year follow-up survey of obstetricians and gynecologists regarding their current opinions about the HPV vaccine

In Japan, the governmental recommendation for HPV vaccination was suspended in June 2013 because of media reports of so-called adverse vaccine events. The HPV vaccination rate in Japan prior to this suspension was almost 70%, but fell afterward to almost zero. To explore ways to bolster HPV vaccination, between 2014 and 2019 we conducted three serial surveys of the opinions of obstetricians and gynecologists about HPV vaccination. This study aimed to discuss the changing attitudes found in this 5-year follow-up survey. In August 2014, January 2017, and June 2019, we posted questionnaires to about 570 obstetricians and gynecologists practicing in Osaka, Japan. All three surveys used the same structured and closed-ended questionnaire, including questions about their personal opinions regarding HPV vaccination. We compared our new results to those of the previous two surveys. The response rate for the latest survey was 51.1% (293/573), which was equivalent to the previous two surveys. Among the responders, 83.3% (244/293) now thought that the Japanese government should restart its HPV vaccine recommendation, and 84.6% (248/293) were already recommending HPV vaccines for teenagers in their daily care. Eleven of 30 doctors (36.7%) had their own teenage daughters vaccinated against HPV after the suspension of recommendation. The rate has maintained an increasing trend from the previous two surveys. This study indicated that the attitude of obstetricians and gynecologists in Japan toward HPV vaccination has changed positively over 5 years. The results should serve as an encouragement to resume the governmental recommendation of HPV vaccines

A survey of 20-year-old Japanese women: how is their intention to undergo cervical cancer screening associated with their childhood HPV vaccination status?

Introduction In Japan, two groups of women, HPV vaccinated and unvaccinated, are approaching age 20, when they should begin cervical cancer screening. To improve Japan’s current poor cervical cancer screening rate, we need to know how these women are thinking about screening. Methods We conducted an internet survey of 20-y-old women, exploring their understanding of HPV and cervical cancer screening. We then gave them leaflets with basic information about HPV and cervical cancer, stressing the importance of early detection by screening. We analyzed the leaflet’s effects on their attitudes based on their vaccination status. Results Our study of 618 women found a significantly higher intention for engagement for cervical cancer screening in women HPV-vaccinated as teenagers (29% versus 17%). They were also more aware that: (1) HPV is transmitted by sexual intercourse (49.1% versus 39.2%); (2) the HPV vaccine prevents cervical cancer (49.0% to 34.0%); and (3) the appropriate cervical cancer screening interval is every 2 y (63.3% versus 56.2%). Women in both groups responded well to the leaflet, with significant improvements in intention to receive screening. However, 65%-67% were not swayed. Discussion HPV-vaccinated women were more knowledgeable about cervical cancer and had a greater intention to receive screening. Our educational leaflet was moderately effective in both groups for increasing intentions to screen, but the majority in both groups were still resistant to screening. Conclusion Japan needs to develop more effective educational programs and tools to vigorously impart the importance of cervical cancer screening
