Our objective was to determine whether intention for future pregnancy affects selected preconception health behaviors that may impact pregnancy outcomes.
Analyses are based on data from a population-based cohort study of women ages 18-45 residing in Central Pennsylvania. A subsample of 847 non-pregnant women with reproductive capacity comprise the analytic sample. We determined the associations between intention for future pregnancy and the pattern in the following health behaviors over a 2-year period: nutrition (fruit and vegetable consumption), folic acid supplementation, physical activity, binge drinking, smoking, and vaginal douching. Multivariable analyses controlled for pregnancy-related variables, health status, health care utilization, and sociodemographic variables.
At baseline, 9% of women were considering pregnancy in the next year, 37% of women were considering pregnancy some other time in the future, and 53% of women were not considering future pregnancy. In multivariable analyses, there were no associations between intention for future pregnancy and maintaining healthy behavior or improving behavior for any of the seven longitudinal health behaviors studied.
The importance of nutrition, folic acid supplementation, physical activity, avoiding binge drinking, not smoking, and avoiding vaginal douching in the preconception period needs to be emphasized by health care providers and policy makers.
本研究旨在确定未来妊娠意向是否会影响可能影响妊娠结局的某些孕前健康行为。
本研究基于宾夕法尼亚州中部居住的 18-45 岁育龄妇女的一项基于人群的队列研究数据进行分析。具有生殖能力的 847 名非妊娠女性的亚样本构成了分析样本。我们确定了未来妊娠意向与以下健康行为模式之间的关联：营养（水果和蔬菜摄入）、叶酸补充、体育活动、狂饮、吸烟和阴道冲洗，为期 2 年。多变量分析控制了与妊娠相关的变量、健康状况、医疗保健利用以及社会人口统计学变量。
在基线时，9%的女性考虑在未来 1 年内怀孕，37%的女性考虑在未来某个时间怀孕，53%的女性不考虑未来怀孕。在多变量分析中，未来妊娠意向与维持健康行为或改善 7 项纵向健康行为中的任何一项均无关联。
医疗保健提供者和政策制定者需要强调营养、叶酸补充、体育活动、避免狂饮、不吸烟和避免阴道冲洗在孕前阶段的重要性。
