目的：了解计划在怀孕前、怀孕6周、10周、26周、38周和产后6个月计划立即怀孕的妇女的饮食模式，并描述特定的生活方式、体重指数(BMI)和社会人口学因素与这些模式的关系。设计：在西班牙地中海城市进行一项贯穿食物消费生殖周期的纵向研究。地点：罗维拉-维吉利大学医学与健康科学学院。对象：总共80名计划立即怀孕的健康女性志愿者。干预：采用连续7天的饮食记录来评估膳食摄入量。探索性因素分析被用来确定每个时期的主要饮食模式。结果：孕前至产后6个月为“含糖加糖”型，妊娠结束前为“蔬菜+肉类”型。“含糖饮料和糖”模式与吸烟呈正相关，与怀孕前和怀孕前三个月的体力活动呈负相关。‘蔬菜和肉类’模式与怀孕前期的BMI呈负相关，而与怀孕10周和38周的年龄呈正相关。结果表明，在整个研究期间，这些饮食模式没有明显的变化。结论：我们发现了两种稳定的饮食模式，从怀孕前到产后。“含糖饮料和糖”模式与孕妇及其后代的健康风险习惯有关。
Objective: To identify dietary patterns in women who are planning immediate pregnancy in preconception, weeks 6, 10, 26 and 38 of pregnancy, and 6 months postpartum, and to describe how particular lifestyles, the body mass index (BMI) and sociodemographic factors are associated to these patterns.Design: Longitudinal study throughout the reproductive cycle of food consumption carried out in a Spanish Mediterranean city.Setting: Faculty of Medicine and Health Sciences, Rovira i Virgili University.Subjects: In total, 80 healthy female volunteers who were planning immediate pregnancy.Interventions: A seven- consecutive-day dietary record was used to evaluate the dietary intake. Exploratory factor analysis was used to identify the main dietary patterns in each of the periods. Fitted multiple linear regression models were used to study the associations between the lifestyle and sociodemographic variables, and each dietary pattern.Results: The `sweetened beverages and sugars' pattern was identified from preconception to 6 months postpartum and the `vegetables and meat' pattern to the end of pregnancy. The `sweetened beverages and sugars' pattern is positively associated with smoking and negatively associated with physical activity before conception and in the first trimester of pregnancy. The `vegetables andmeat' pattern is negatively associated with the BMI during the preconception period and positively associated with age in weeks 10 and 38 of pregnancy. It is shown that the patterns do not change significantly throughout the period studied.Conclusions: We have identified two stable dietary patterns from preconception to postpartum. The `sweetened beverages and sugars' pattern is associated with habits of risk for the health of the pregnant woman and her offspring.
