Eating behaviours were assessed among pregnant women in a mid-sized Canadian city.
As part of the Prenatal Health Project, we interviewed 2313 pregnant women in London, Ontario. Subjects also completed a food frequency questionnaire. Recruitment took place in ultrasound clinics at 10 to 22 weeks of gestation. The main outcome measures were number of daily servings for each food group, measured against the minimum number recommended by the 2007 Eating Well with Canada's Food Guide (CFG), the proportion of women consuming the recommended number of servings for each and all of the four food groups, and factors associated with adequate consumption. We also determined the number of servings of "other foods." Analysis included descriptive statistics and logistic regression, all at p<0.05.
A total of 3.5% of women consumed the recommended number of servings for all four food groups; 15.3% did not consume the minimum number of servings of foods for any of the four food groups. Women for whom this was their first pregnancy were less likely to consume the recommended number of servings from all four food groups (odds ratio=0.41; confidence interval=0.23, 0.74).
Very few pregnant women consumed food group servings consistent with the 2007 recommendations. Strategies to improve dietary behaviours must focus on the establishment of healthy eating behaviours among women of reproductive age.
对加拿大一个中等规模城市的孕妇的饮食行为进行评估。
作为产前健康项目的一部分,我们对安大略省伦敦市的2313名孕妇进行了访谈。受试者还完成了一份食物频率问卷。招募工作在妊娠10至22周的超声诊所进行。主要结局指标包括每个食物组的每日食用份数,根据2007年《加拿大食物指南》(CFG)推荐的最低份数进行衡量;食用每个及所有四个食物组推荐份数的女性比例;以及与充足摄入相关的因素。我们还确定了“其他食物”的食用份数。分析包括描述性统计和逻辑回归,所有分析的p值均<0.05。
共有3.5%的女性食用了所有四个食物组的推荐份数;15.3%的女性未达到四个食物组中任何一个食物组的最低食用份数。首次怀孕的女性食用所有四个食物组推荐份数的可能性较小(优势比=0.41;置信区间=0.23,0.74)。
很少有孕妇的食物组食用份数符合2007年的建议。改善饮食行为的策略必须侧重于在育龄女性中建立健康饮食行为。
