Although pregnancy intention is strongly associated with contraceptive use, little is known about the interaction between pregnancy intention and attitude, or how they jointly affect contraceptive use.
Cross-sectional data from a national survey of women veterans who receive care within the Veterans Affairs Healthcare System were used to examine relationships among pregnancy intention (in next year, in >1 year, never, not sure), attitude toward hypothetical pregnancy (worst thing, neutral, best thing), and contraceptive use among women at risk for unintended pregnancy. Bivariate and multivariable analyses assessed associations between pregnancy intention and attitude, both separately and jointly, with contraceptive use. Multinomial regression assessed the relationship of intention and attitude with contraceptive method effectiveness.
Among 858 women at risk of unintended pregnancy, bivariate analysis demonstrated that pregnancy intention and attitude were associated, but not perfectly aligned. In logistic regression models including both variables, intention of never versus in next year (adjusted odds ratio [aOR], 2.78; 95% confidence interval [CI], 1.34-5.75) and attitude of worst thing versus best thing (aOR, 2.86; 95% CI, 1.42-5.74) were each positively associated with contraception use. Among women using contraception, intention of never (aOR, 3.17; 95% CI, 1.33-7.59) and attitude of worst thing (OR, 2.09; 95% CI, 1.05-4.17) were associated with use of highly effective (e.g., intrauterine devices and implants) versus least effective (e.g., barrier) methods.
These findings support prior research suggesting that pregnancy intention alone does not fully explain contraceptive behaviors and imply that attitude toward pregnancy plays an important role in shaping contraceptive use independent of pregnancy intentions.
尽管怀孕意愿与避孕措施的使用密切相关,但人们对怀孕意愿与态度之间的相互作用,以及它们如何共同影响避孕措施的使用知之甚少。
本研究使用来自退伍军人事务部医疗保健系统中接受护理的女性退伍军人全国调查的横断面数据,来研究处于意外怀孕风险中的女性的怀孕意愿(明年、>1 年、从不、不确定)、对假设怀孕的态度(最糟糕的事情、中立、最好的事情)与避孕措施使用之间的关系。使用二变量和多变量分析来评估怀孕意愿和态度之间的关联,包括单独和联合使用避孕措施的情况。使用多项回归评估怀孕意愿和态度与避孕方法有效性的关系。
在 858 名有意外怀孕风险的女性中,二变量分析表明怀孕意愿和态度之间存在关联,但并不完全一致。在包含这两个变量的逻辑回归模型中,从未怀孕与明年怀孕的意愿(调整后的优势比 [aOR],2.78;95%置信区间 [CI],1.34-5.75)以及最糟糕的事情与最好的事情的态度(aOR,2.86;95% CI,1.42-5.74)与避孕措施的使用均呈正相关。在使用避孕措施的女性中,从未怀孕的意愿(aOR,3.17;95% CI,1.33-7.59)和最糟糕的事情的态度(OR,2.09;95% CI,1.05-4.17)与使用高效(例如宫内节育器和植入物)与低效(例如屏障)避孕方法相关。
这些发现支持了先前的研究,表明怀孕意愿本身并不能完全解释避孕行为,并暗示对怀孕的态度在塑造独立于怀孕意愿的避孕措施使用方面起着重要作用。
