A cross sectional study on fertility knowledge in Japan, measured with the Japanese version of Cardiff Fertility Knowledge Scale (CFKS-J).
BACKGROUND: A recent survey of 79 countries showed that fertility knowledge was
lower in Japan than in any other developed country. Given the fertility decline
in Japan and the importance of fertility knowledge, we conducted an online survey
to examine fertility knowledge and the related factors for effective public
METHODS: We studied people aged 18-59 years old, n = 4,328 (the "General" group),
and also people who had been trying to conceive for at least six months, 18-50
years old, n = 618 (the "Triers" group). Fertility knowledge was assessed using
the Japanese version of the 13-item Cardiff Fertility Knowledge Scale (CFKS-J).
All participants provided socio-demographic and fertility information.
Participants also completed a 14-item health literacy scale and an 11-item health
numeracy scale. We asked participants who were aware of age-related decline in
fertility when and where they first acquired that knowledge.
RESULTS: The average percentages of CFKS-J items answered correctly were 53.1% in
the Triers group and 44.4% in the General group (p < 0.001). Multivariate linear
regression models showed in the Triers group greater fertility knowledge was
associated with greater health literacy and prior medical consultation regarding
their fertility. In the General group greater fertility knowledge was associated
with being female, younger, university educated, currently trying to conceive,
non-smoking, having higher household income, having higher health literacy and
having higher health numeracy. Of those who were aware of the age-related decline
in fertility, around 3% first learned the fact "at school," and around 65% first
learned it "through mass media" or "via the Internet." More than 30% of the
respondents first learned it "less than 5 years before" the survey.
CONCLUSIONS: Although fertility knowledge had improved since a previous study,
possibly due to recent media coverage of age-related infertility, it was still
low. Educational interventions, both in schools and in the community, may be
needed to increase fertility knowledge in the general population because most
people obtain fertility knowledge from mass media, which has been shown to often
present distorted and inaccurate fertility information.
