BACKGROUND
We investigated periconceptional awareness and the use of folic acid tablets 3 years after the 1995 campaign in the northern Netherlands. We studied whether the socioeconomic differences we found in 1996 with respect to awareness and use of folic acid remained in 1998.
METHODS
The present study took place in 1998. Pregnant women were asked to complete a questionnaire.
RESULTS
A total of 452 women completed the questionnaire in 1998. Sixty percent of the women with a lower level of education and 85% of the women with a higher level of education had heard of folic acid before pregnancy. Newspapers and magazines were the most often cited sources of information. Fifty percent of the women with a lower educational level used folic acid, while this figure was 80% for the group with higher education.
CONCLUSION
Awareness and use of folic acid increased after the 1995 campaign. However, socioeconomic differences with respect to awareness of folic acid remained and even increased with respect to knowledge of the advised period. Use of folic acid is also associated with level of education more strongly than in 1996. Therefore, fortification of staple foods is an attractive option.
背景
我们在荷兰北部1995年开展宣传活动3年后，调查了受孕前对叶酸片的知晓情况及使用情况。我们研究了1996年发现的在叶酸知晓和使用方面的社会经济差异在1998年是否依然存在。
方法
本研究于1998年进行。要求孕妇填写一份问卷。
结果
1998年共有452名妇女完成了问卷。60%文化程度较低的妇女和85%文化程度较高的妇女在怀孕前听说过叶酸。报纸和杂志是最常被提及的信息来源。50%文化程度较低的妇女使用了叶酸，而文化程度较高组的这一比例为80%。
结论
1995年宣传活动后，对叶酸的知晓和使用有所增加。然而，在叶酸知晓方面的社会经济差异依然存在，甚至在建议服用时期的知识方面差异有所增大。叶酸的使用与文化程度的关联也比1996年更为紧密。因此，主食强化是一个有吸引力的选择。
