This paper evaluates a study fielded in Bangladesh in 1975 to test the hypothesis that ubiquitous availability of pills and condoms in a rural, traditional, noncontracepting population would increase contraceptive use and reduce fertility. Treatment and comparison areas were designated in Matlab, an area with accurate and complete demographic data. Use prevalence peaked at 18 percent in the first three months of the project and declined thereafter. Project activities continued until 1977. Results show that between-treatment fertility differentials were 10 percent in the first year of program impact, but that effects dissipated with time.
本文评估了1975年在孟加拉国开展的一项研究,以检验以下假设:在农村、传统、未采取避孕措施的人群中普遍提供避孕药和避孕套会增加避孕措施的使用并降低生育率。在拥有准确和完整人口数据的Matlab地区指定了治疗区和对照区。在项目的前三个月,使用率峰值达到18%,此后下降。项目活动持续到1977年。结果表明,在项目影响的第一年,治疗组和对照组之间的生育率差异为10%,但随着时间的推移,效果逐渐消失。
