The proximate determinants of fertility framework, developed in its current form by Bongaarts, has been used extensively by researchers for the past 20 years. Since the initial framework was developed, a wealth of new survey data on the proximate determinants has become available. This article reviews the new data and past experiences and suggests modifications to the framework that would take advantage of this experience. The major modifications suggested are (1) the use of sexual activity rather than marriage to indicate exposure to pregnancy; (2) a revision of the sterility index to measure infecundity from all causes; (3) a revised index of contraception that accounts for the fact that users of sterilization may become infecund before age 49; and (4) a revised definition and estimate of total fecundity.
由邦加茨发展成当前形式的生育近因决定因素框架，在过去20年里被研究人员广泛使用。自最初的框架形成以来，关于生育近因决定因素的大量新调查数据已可获取。本文回顾了这些新数据和以往经验，并建议对该框架进行修改，以利用这些经验。建议的主要修改内容包括：（1）使用性活动而非婚姻来表明怀孕风险；（2）修订不育指数以衡量各种原因导致的不孕；（3）修订避孕指数，以考虑绝育使用者可能在49岁之前就出现不孕的情况；（4）修订总生育力的定义和估计方法。
