该研究旨在描述加拿大女性妊娠期体重增加的总体情况，并评估妊娠期体重增加的人口、社会经济、孕产妇和妊娠相关特征，包括揭示高于或低于加拿大卫生部建议范围的预测因素。本研究是对 2005/2006 年在加拿大各省和地区生育过单胎活产的 15 岁女性的生育经历调查的二次数据分析。考虑的结果变量是推荐指南范围内和之外的妊娠体重增加。使用多元统计技术考虑了各种因素，包括人口、社会经济、孕产妇和妊娠相关特征。进行引导是为了考虑复杂的抽样设计。三分之一的女性体重增长在推荐指南范围内 (32.6%)，18.7% 的女性体重增长低于推荐指南，48.7% 的女性体重增长高于推荐指南。超过一半的超重 (67.6%) 或肥胖女性 (60.0%) 体重增加超过指导值，而社会经济地位较低的女性更有可能体重增加超过建议范围。相反，作为移民、经产妇以及在怀孕期间出现健康问题，与怀孕期间体重增加较少以及体重增加不足以满足最低体重增加指南的可能性较高有关。在加拿大，几乎一半的女性怀孕期间体重增加超过了建议的指南。这些发现可能有助于设计针对那些有超出推荐指南的增重风险的干预措施，并减少与妊娠期体重增加不足或过度相关的后果。
The study aims to describe overall gestational weight gain among Canadian women and to assess demographic, socio-economic, maternal, and pregnancy-related characteristics of gestational weight gain including uncovering the predictors above or below the range recommended by Health Canada. This study proceeds as a secondary data analysis of the Maternity Experiences Survey targeting women aged a parts per thousand yen15 years who had singleton live births in the Canadian provinces and territories in 2005/2006. The outcome variable considered was gestational weight gain within and outside the recommended guidelines. Various factors including demographic, socio-economic, maternal, and pregnancy-related characteristics were considered using multivariate statistical techniques. Bootstrapping was performed to account for the complex sampling design. One-third of women gained within the recommended guideline (32.6%), 18.7% gained below, and 48.7% gained above the recommended guideline. More than half of overweight (67.6%) or obese women (60.0%) gained above the guideline, and women with lower socio-economic status were more likely to gain above the recommended range. Conversely, being an immigrant, multiparous, and having health problems during pregnancy were associated with less weight gain during pregnancy as well as higher odds of gaining insufficient weight to meet the minimal weight gain guideline. In Canada, almost half of the women gain above the recommended guideline for weight gain in pregnancy. The findings may be useful to design interventions that target those at risk of gaining outside of the recommended guidelines and to reduce outcomes associated with inadequate or excessive gestational weight gain.
