Folic acid in the prevention of neural tube defects: awareness among laywomen and healthcare providers in Japan.
It is known that neural tube defects are folic acid preventable congenital anomalies. We investigated to what extent this information was disseminated among laywomen and healthcare providers. Questionnaire studies were conducted twice, in 2002 and 2007, for four groups of laywomen and seven groups of healthcare providers in Japan regarding awareness, folic acid supplements and healthy diets. Awareness among laywomen was less than 20%, except for families who had experience with spina bifida in 2002, and 5 years later only pregnant women showed a significant increase in awareness. Awareness among healthcare providers varied from 12 to 76%, depending on their profession, and this proportion increased in five of the seven groups in 2007. The majority of laywomen obtained their information from mass media, while the majority of healthcare providers received information through media for professionals. Laywomen who used folate supplements and healthcare providers who recommended them were initially fewer than 25 and 37%, respectively. Five years later, however, pregnant women who used folic acid supplements increased from 9.1 to 43.1%. As awareness among non-pregnant laywomen and some healthcare providers is considerably low, information should be presented repeatedly to these groups. The difficulty in getting women to consume folic acid supplements is an argument for the government to require folic acid fortification of grains so that the prevention of neural tube defects can be maximized.
