An analysis of data from the 1973 and 1976 National Surveys of Family Growth indicates that although marital disruption affects contraceptive practice, the patterns of contraceptive behavior among separated women who remain sexually active are very similar to those of women who remain married. Women about to separate rely less on barrier methods than do continuously married women, and this pattern persists after separation. It is likely that coitus-related methods are less frequently used because they require cooperation between the spouses. In addition, coitus-related methods are probably used less after separation because these methods are less effective, and unintended pregnancies are less desirable in the intermarital or postseparation period. As might be expected, both before and after separation, women who experience marital dissolution are less likely than the continuously married to be sexually active. The difference is greater after separation, but the major finding is the similarity of separated and continuously married women with respect to both coitus and contraceptive protection.
对1973年和1976年全国家庭生育调查数据的分析表明，尽管婚姻破裂会影响避孕措施的使用，但仍保持性活跃的分居女性的避孕行为模式与仍处于婚姻关系中的女性非常相似。即将分居的女性比持续婚姻中的女性更少依赖屏障避孕法，且这种模式在分居后依然存在。很可能与性交相关的避孕方法使用频率较低，因为它们需要配偶双方的配合。此外，分居后与性交相关的避孕方法可能使用得更少，因为这些方法效果较差，而且在婚内或分居后意外怀孕更不可取。不出所料，在分居前后，经历婚姻解体的女性比持续婚姻中的女性性活跃的可能性更小。分居后的差异更大，但主要发现是分居女性和持续婚姻中的女性在性交和避孕保护方面具有相似性。
