In total, another 40 experts were involved in the revision of the information on the website (a detailed list of experts can be found on the bottom of the page ‘gezondzwangerworden.be/over-de-website’). Because of the importance of this process, experts were carefully chosen after consultation with the commissioning party (Zorg & Gezondheid) and the IEC. Thus, a multidisciplinary group was chosen to revise the part of the contents corresponding to their field of expertise. As such, gynaecologists, general practitioners, and midwives with an expertise in preconception care were involved; as were specialists in smoking cessation, obesity, and genetics; nutritional specialists; pharmacists; members of public services on occupational health, sexually transmitted infections, and hygiene; and delegates of health insurance companies, federations of birth defects, and members of the Dutch health council.
