目的：为了推进知识的饮食质量的决定因素在怀孕期间，通过关注个人特点和食品environment.Design：横断面研究，参与者从产前健康项目被链接到一个地理数据集的家庭地址。使用地理信息系统测量了快餐店、便利店和杂货店的可及性（ArcGIS9.3）.设置：孕妇（n = 2，282）于2002年至2005年在加拿大安大略的伦敦招募。主要结果测量：饮食质量使用经验证的食物频率问卷和加拿大妊娠饮食质量指数进行测量。分析：单变量和多变量线性回归计算预测变量的加拿大饮食质量指数pregnancy.Results：孕妇谁出生在加拿大，习惯法，未经产，较少的体力活动，吸烟者，更焦虑，或缺乏家庭的支持，平均饮食质量较低。快餐店，便利店和杂货店内500米的参与者的住宅的存在与饮食质量控制后的个人variables.Conclusions和影响：饮食环境似乎并没有很大的影响，在怀孕期间的饮食质量。需要进一步研究以确定孕妇饮食质量低的其他潜在原因。
Objective: To advance the knowledge of determinants of diet quality in pregnancy by focusing on both personal characteristics and the food environment.Design: Cross-sectional study in which participants from the Prenatal Health Project were linked to a geographic dataset by home address. Access to fast food, convenience stores, and grocery stores was measured using a geographic information system (ArcGIS9.3).Setting: Pregnantwomen (n = 2,282) were recruited between 2002 and 2005 in London, Ontario, Canada.Main Outcome Measure: Dietary quality was measured using a validated food frequency questionnaire and the Canadian Diet Quality Index for Pregnancy.Analysis: Univariate and multivariate linear regressions were calculated with the predictor variables on the Canadian Diet Quality Index for Pregnancy.Results: Pregnant women who were born in Canada, common-law, nulliparous, less physically active, smokers, more anxious, or lacking family support had lower diet quality on average. Presence of fastfood restaurants, convenience stores, and grocery stores within 500 m of participants' homes was not associated with diet quality after controlling for personal variables.Conclusions and Implications: The food environment does not seem to have a large influence on diet quality in pregnancy. Further research is needed to determine other potential reasons for low diet quality among pregnant women.
