Previous studies have suggested that women have low dietary intake of fruits and vegetables. This study's objective was to test the effectiveness of a novel nutrition intervention (education about prenatal flavor learning) on increasing fruit and vegetable intake in a group of primarily Latina women at an urban prenatal clinic.
The Harvard Service Food Frequency Questionnaire (HSFFQ) was administered to 2 groups at the same clinic at 2 time points for each group. The first group was a nonintervention, comparison group. The second (intervention) group received specific information about how a pregnant woman's food choices can influence subsequent solid food preferences of her infant, with encouragement given to increase fruit and vegetable choices. The HSFFQ was administered pre- and post-intervention for this group.
Combined fruit and vegetable intake declined from the administration of Q#1 to Q#2 in both the comparison (n = 28) and intervention (n = 31) groups. The decline was primarily the result of a decrease in vegetable intake, but it was not statistically significant. In the comparison group, only 23.3-36.6% of women were eating adequate daily servings of vegetables, and in the intervention group 32.3%-38.7%. In both the comparison and intervention groups, over 74% of the women were eating adequate daily servings of fruit at both time points.
In this Latina population of pregnant women, there was no difference in fruit and vegetable intake after receiving education about prenatal flavor learning. These findings suggest that education alone may not be sufficient to change health behaviors.
先前的研究表明,女性水果和蔬菜的饮食摄入量较低。本研究的目的是测试一种新型营养干预措施(关于产前味觉学习的教育)对增加城市产前诊所一组主要为拉丁裔女性的水果和蔬菜摄入量的有效性。
在同一诊所对两组人员在两个时间点分别进行哈佛服务食物频率问卷(HSFFQ)调查。第一组为非干预对照组。第二组(干预组)收到关于孕妇的食物选择如何影响其婴儿随后对固体食物偏好的具体信息,并受到鼓励增加水果和蔬菜的选择。对该组在干预前后进行了HSFFQ调查。
对照组(n = 28)和干预组(n = 31)从第一次问卷调查(Q#1)到第二次问卷调查(Q#2),水果和蔬菜的总摄入量均有所下降。下降主要是蔬菜摄入量减少所致,但无统计学意义。在对照组中,只有23.3%-36.6%的女性每天摄入足够的蔬菜量,干预组为32.3%-38.7%。在对照组和干预组中,超过74%的女性在两个时间点每天都摄入足够的水果量。
在这组拉丁裔孕妇中,接受产前味觉学习教育后,水果和蔬菜摄入量没有差异。这些发现表明,仅靠教育可能不足以改变健康行为。
