Abstract

Aim

To evaluate the effectiveness of an individualized nutritional education program in promoting adequate nutrient intake in pregnant women.

Methods

A stratified randomized controlled trial was conducted. Participants were stratified by factors affecting the primary outcome and randomly assigned to the intervention or control groups. Intervention group participants received an individualized 30-min booklet-based education program in their 2nd and 3rd trimesters; the control group received usual care. The primary outcome was protein intake after the intervention, which was compared between the intervention and control groups. Secondary outcomes included comparing the amount of increase of protein before and after the intervention. Nutrient intake was measured using a self-administered short dietary history questionnaire, and analyses of covariance and t tests were performed.

Results

Of the 130 participants, 66 were assigned to the intervention group and 64 to the control group. There was no difference in protein intake between the two groups after the intervention (p = .051, 95% CI [−0.021, 12.4]). Comparing the increase in protein intake before and after intervention, the intervention group was 7.4 g/day higher than that of the control group (p = .040; F = 4.31; effect size = 0.36).

Conclusions

The primary outcome, a comparison of protein intake between the groups after the program, revealed no significant differences. However, on comparing the amount of protein increase before and after the intervention, the intervention group's increase was significantly higher than that of the control group. Results indicate the potential for individualized face-to-face interventions for pregnant women in Japan.

孕妇个性化营养教育计划的效果:日本的随机对照试验
目的评估个性化营养教育计划在促进孕妇摄入充足营养方面的效果。 方法进行分层随机对照试验。根据影响主要结果的因素对参与者进行分层,并随机分配到干预组或对照组。干预组的参与者在怀孕第 2 和第 3 个月接受 30 分钟基于小册子的个性化教育计划;对照组接受常规护理。主要结果是干预后的蛋白质摄入量,并在干预组和对照组之间进行比较。次要结果包括比较干预前后蛋白质的增加量。营养素摄入量采用自填式简短饮食史问卷进行测量,并进行协方差分析和 t 检验。干预后,两组的蛋白质摄入量没有差异(p = .051,95% CI [-0.021, 12.4])。比较干预前后蛋白质摄入量的增加情况,干预组比对照组每天多摄入 7.4 克蛋白质(p = .040;F = 4.31;效应大小 = 0.36)。然而,在比较干预前后蛋白质的增加量时,干预组的增加量明显高于对照组。研究结果表明,针对日本孕妇的个性化面对面干预很有潜力。
