An examination of the characteristics of contraceptive acceptors in a family planning program in rural Bangladesh revealed trends of declining age and number of living children among new acceptors. A time series analysis of the age-specific acceptance rates confirmed the observation, indicating that over time the program succeeded in attracting younger and low-parity women. The high use prevalence rates resulted in fertility levels that were 25 percent lower in the program area than in the comparison area. The decline in the fertility levels during the first program year was mainly due to a large decline in fertility among women over age 35, but in the second year, the contribution made by women 30-35 years old was substantial.
对孟加拉国农村计划生育项目中避孕措施接受者特征的一项调查显示，新接受者的年龄呈下降趋势，存活子女数量也在减少。对特定年龄接受率的时间序列分析证实了这一观察结果，表明随着时间的推移，该项目成功吸引了更年轻、子女数量少的女性。高使用率导致项目地区的生育率比对照地区低25%。项目第一年生育率的下降主要是由于35岁以上女性生育率大幅下降，但在第二年，30至35岁女性的贡献很大。
