本研究探讨了1978-90年孟加拉国产后闭经长度的趋势和决定因素。数据来自Matlab项目。样本包括1978-80年和1988-89年两年内出生的队列的每队列6000名妇女。在索引子女出生后36个月内可获得生殖和哺乳记录。研究结果表明，产后闭经的持续时间约为13个月的分娩在1978年至1983年。1982-83年出生队列的平均持续时间为13.5个月，1988-89年出生队列的平均持续时间为9.4个月。单就一九八九年而言，中位数持续时间进一步下降至8.6个月。七年的下降幅度相当于减少了36%。研究结果表明，年龄和产后闭经的持续时间呈正相关。所有年龄组的中位持续时间都有所下降。中位持续时间较短的是子女少于两个且受教育程度较高的妇女。1984- 1985年，母乳喂养时间达到高峰，为34.3个月，1986- 1987年下降到30.7个月。全母乳喂养持续时间从1978-79年队列的约6个月下降到1982 - 88年队列的5.2个月，并落后于产后闭经的持续时间。1982-83年，受过高等教育的母亲的全母乳喂养率下降，1984-85年，未受过教育和教育程度较低的妇女的全母乳喂养率下降。母乳喂养妇女的年龄模式不一致。年龄最大的母亲母乳喂养的时间最短。年龄最小的群体呈下降趋势。母乳喂养持续时间随着存活儿童数量的增加而增加。然而，另一种趋势显示，无论存活子女的数量如何，持续时间最初增加，然后下降。提示全母乳喂养对产后闭经时间的长短有重要影响。避孕药具的使用率从1977年的24%上升到1984年的39%。中位生育间隔从38.7个月增加到48.8个月，所有年龄组和胎次组都有增加。营养不良被认为与产后闭经无关。这一趋势清楚地反映了产后闭经持续时间的下降，但母乳喂养或避孕措施的影响的性质尚不清楚。
This study examines the trends in and determinants of length of postpartum amenorrhea during 1978-90 in Bangladesh. Data are obtained from the Matlab project. The sample comprises 6000 women per cohort for cohorts born in two year periods during 1978-80 and 1988-89. Reproductive and lactation records are available for up to 36 months following the birth of the index child. Findings indicate that the duration of postpartum amenorrhea is around 13 months for births during 1978-83. The median duration is 13.5 months for the birth cohort for 1982-83 and 9.4 months for the birth cohort for 1988-89. For 1989 alone the median duration is a further decline to 8.6 months. The seven year decline amounts to a 36% reduction. Findings indicate that age and duration of postpartum amenorrhea are positively related. All age groups show a decline in median duration. The shorter median durations occur among women with fewer than two living children and higher levels of education. Duration of breast feeding peaks in 1984-85 at 34.3 months and then declines to 30.7 months in 1986-87. Full breast feeding duration declines from around 6 months for cohorts 1978-79 to cohorts 1982-88 to 5.2 months in 1986-87 and lags behind durations of postpartum amenorrhea. Full breast feeding declines occur after the 1982-83 cohort among mothers with higher education and after the 1984-85 cohort for uneducated and less educated women. Age patterns of breast feeding women are inconsistent. The oldest mothers have the shortest breast feeding durations. The youngest cohorts show a decreasing trend. Breast feeding durations increase with an increase in the number of living children. However another trend shows initial increases in duration and then declines regardless of the number of living children. The suggestion is that full breast feeding may be important in determining the length of postpartum amenorrhea duration. Contraceptive use increases from 24% in 1977 to 39% in 1984. Median birth intervals increase from 38.7 to 48.8 months and increases pertain to all age and parity groups. Malnutrition is considered to be unrelated to postpartum amenorrhea periods. The trend is clearly reflective of declining postpartum amenorrhea duration, but the nature of the impact of breast feeding or contraceptive use is not clear.
