Woman's nutritional status, before and during pregnancy, is a strong determinant of health outcomes in the mother and newborn. Gestational weight gain and postpartum weight retention increases risk of overweight or obesity in the future and they depend on the pregestational nutritional status and on food consumption and eating behavior during pregnancy. Eating behavior during pregnancy may be the cause or consequence of mood changes during pregnancy, especially depression, which increases likelihood of postpartum depression. In Brazil, a study carried out in the immediate postpartum period found that one in three women experienced some type of violence during pregnancy. Violence and depression are strongly associated and both exposures during pregnancy are associated with increased maternal stress and subsequent harm to the infant. The main objectives of this study are: to identify food intake and eating behaviors patterns; to estimate the prevalence of common mental disorders and the experience of violence during and after pregnancy; and to estimate the association between these exposures and infant's health and development.
METHODS/DESIGN: This is a cohort study of 780 pregnant women receiving care in 18 primary care units in two cities in Southern Brazil. Pregnant women were first evaluated between the 16th and 36th week of pregnancy at a prenatal visit. Follow-up included immediate postpartum assessment and around the fifth month postpartum. Information was obtained on sociodemographic characteristics, living circumstances, food intake, eating behaviors, mental health and exposure to violence, and on infant's development and anthropometrics measurements.
This project will bring relevant information for a better understanding of the relationship between exposures during pregnancy and how they might affect child development, which can be useful for a better planning of health actions aiming to enhance available resources in primary health care.
女性在怀孕前后的营养状况是母亲和新生儿健康结果的重要决定因素。孕期体重增加和产后体重滞留会增加未来超重或肥胖的风险，这取决于孕前的营养状况以及孕期的食物摄入和饮食行为。孕期的饮食行为可能是孕期情绪变化（尤其是抑郁）的原因或结果，而抑郁会增加产后抑郁的可能性。在巴西，一项在产后即刻进行的研究发现，三分之一的孕妇在怀孕期间经历过某种形式的暴力。暴力和抑郁密切相关，孕期的这两种暴露都与母亲压力增加以及随后对婴儿造成伤害有关。本研究的主要目的是：确定食物摄入和饮食行为模式；估计常见精神障碍的患病率以及怀孕期间和之后的暴力经历；并估计这些暴露与婴儿健康和发育之间的关联。
方法/设计：这是一项在巴西南部两个城市的 18 个初级保健单位接受护理的 780 名孕妇的队列研究。孕妇在怀孕第 16 周到第 36 周期间的产前检查中首次接受评估。随访包括产后即刻评估和产后第五个月左右的评估。收集的信息包括社会人口特征、生活环境、食物摄入、饮食行为、心理健康和暴力暴露情况，以及婴儿的发育和体格测量情况。
该项目将提供有关孕期暴露情况及其如何影响儿童发育的重要信息，这有助于更好地了解它们之间的关系，从而为更好地规划旨在加强初级保健中现有资源的卫生行动提供有用信息。
