Approximately 40% of women of childbearing age report that they are attempting to lose weight. No professional medical organization recommends attempting to lose weight during pregnancy because of the possible risks to both mother and baby. Since half of all pregnancies are unintended, women may attempt to lose weight before they know they are pregnant, and some women may continue or initiate weight loss attempts even after they know they are pregnant. This study examines the extent to which pregnant women report attempting to lose weight and associated sociodemographic and health characteristics.
We used aggregated multiple-year data (1996-2003) from the Behavioral Risk Factor Surveillance System to assess the prevalence of attempting to lose weight among pregnant women and the extent to which sociodemographic and health characteristics are associated with the behavior.
The prevalence of attempting to lose weight during pregnancy was 8.1%. Attempting to lose weight during pregnancy was associated with age 35-44 years, Hispanic ethnicity, obesity, alcohol consumption, and mental distress during the previous month.
A substantial proportion of pregnant women attempt to lose weight. Preconception and prenatal care should include counseling women to achieve a healthy weight before becoming pregnant, to maintain healthy weight during pregnancy, and not to attempt weight loss during pregnancy. Further research should be conducted to understand how attempting weight loss during pregnancy translates into dietary change and weight loss and associated maternal and fetal outcomes.
约40%的育龄妇女表示她们正在尝试减肥。由于对母婴均存在潜在风险，没有专业医学组织建议在孕期尝试减肥。由于半数怀孕是意外怀孕，女性可能在得知自己怀孕之前就尝试减肥，而且一些女性甚至在得知自己怀孕后仍会继续或开始减肥尝试。本研究调查了孕妇中报告尝试减肥的比例以及相关的社会人口学和健康特征。
我们使用了行为危险因素监测系统多年汇总数据（1996 - 2003年）来评估孕妇中尝试减肥的患病率以及社会人口学和健康特征与该行为的关联程度。
孕期尝试减肥的患病率为8.1%。孕期尝试减肥与年龄35 - 44岁、西班牙裔种族、肥胖、饮酒以及前一个月的精神困扰有关。
相当一部分孕妇尝试减肥。孕前和孕期保健应包括向女性提供咨询，使其在怀孕前达到健康体重，孕期保持健康体重，并且在孕期不要尝试减肥。应开展进一步研究，以了解孕期尝试减肥如何转化为饮食变化、体重减轻以及相关的母婴结局。
