背景：在加拿大，孕妇通常会参考加拿大食品指南 (CFG)，这是一套旨在促进充足营养摄入的国家饮食建议。还建议孕妇在医学研究所指南范围内增加体重，该指南因孕前体重指数（BMI）而异。然而，CFG 建议并未考虑孕前 BMI，也没有提供有关“不太健康”(LH) 食物的指导。 目的：本研究的目的是根据 CFG 建议的遵守情况和 LH 食物的摄入量对女性的饮食进行评分，并通过孕前 BMI 检查这些饮食评分之间的差异。 方法：参加 APrON（艾伯塔省妊娠结局和营养）前瞻性队列研究的参与者在妊娠中期完成了 24 小时回忆 (n = 1630)。根据满足的每个每日饮食 CFG 建议创建评分，范围为 0 到 9。8 个 LH 食物组的消耗量（每天克数）的分布评分为 0（无）或 1、2 或 3（分别代表最低、中间或最高三分位），并求和得出总 LH 评分为 0-24。 结果：尽管与体重不足或正常的女性相比，孕前超重或肥胖的女性较少符合每天食用 7-8 份水果或蔬菜的具体建议（分别为 47% 和 41% 与 50% 和 54%），但孕前 BMI 状况满足 CFG 建议的情况几乎没有差异。尽管差异很小，但与体重正常的女性相比，孕前肥胖女性的 CFG 评分较低（β = -0.28；95% CI：-0.53，-0.02），LH 评分较高（β = 0.45；95% CI：0.04，0.86）。 结论：研究结果表明，可能需要更多地关注考虑孕前 BMI 的饮食建议的个体化咨询。
Background: In Canada, pregnant women are typically referred to Canada's Food Guide (CFG), a set of national dietary recommendations designed to promote adequate nutrient intake. Pregnant women are also advised to gain weight within the Institute of Medicine guidelines, which differ by prepregnancy body mass index (BMI). However, CFG recommendations do not account for prepregnancy BMI and provide no guidance on “less healthy” (LH) foods. Objective: The aim of this study was to score women's diets according to adherence to CFG recommendations and consumption of LH foods and to examine differences between these diet scores by prepregnancy BMI. Methods: Participants enrolled in the APrON (Alberta Pregnancy Outcomes and Nutrition) prospective cohort study completed a 24-h recall in their second trimester (n = 1630). A score was created on the basis of each daily dietary CFG recommendation met, ranging from 0 to 9. The distribution of consumption (grams per day) of 8 LH food groups was given a score of 0 (none) or 1, 2, or 3 (representing the lowest, middle, or highest tertiles, respectively) and summed giving a total LH score of 0–24. Results: There were few differences in CFG recommendations met by prepregnancy BMI status, although fewer women who were overweight or obese prepregnancy met the specific recommendation to consume 7–8 servings of fruit or vegetables/d than did those who were under- or normal weight (47% and 41% compared with 50% and 54%, respectively). Although differences were small, women who were obese prepregnancy had lower CFG scores (β = −0.28; 95% CI:−0.53, −0.02) and higher LH scores (β = 0.45; 95% CI: 0.04, 0.86) than did those who were normal weight. Conclusion: The study results suggest that more attention may need to be paid to individualized counseling on dietary recommendations that take account of prepregnancy BMI.
