2 Background A spontaneous abortion is a public health problem in Indonesia. Interpregnancies interval is considered one of many risk factors for spontaneous abortion. Interpregancies and birth intervals have been used to promote MCH - FP programmes as a key reducing maternal and child mortality

3 Keys to Reducing Maternal and Child Mortality
The Problem— Births are risky when they are: “Too many” “Too close together” Or when they occur among women who are: “Too young” “Too old” One Solution—Avoid “Too close together” through an Optimal Birth Spacing Interval Health risks related to maternal and child mortality have been summarized as "the four too's.” Births are risky when they are: Too many, or Too close together, or when they occur among women who are Too young, or Too old. It has long been known that avoiding births that are “too close together” is advantageous to maternal and child health. New studies show the importance and significance of the concept of birth spacing.

4 What Is the Policy of Optimal Birth Spacing?
The length of time needed between births to minimize the risks for adverse health outcomes—new research indicates this is “three years or longer.” But: “How long”? First, an overview. What is Optimal Birth Spacing? Over the years, research has shown that when families space the births of their children two years apart, their children are more likely to survive and be healthy. New research has shown that although two-year spacing is good, a longer interval is best. In this presentation, we will refer to this best interval—when the risks for adverse health outcomes are lowest—as the “optimal” birth spacing interval. Most research indicates that the “optimal” interval for child and maternal survival is three years or longer. Although birth spacing is a fundamental part of family planning, it is often underemphasized by programs. How do we know this?: In almost all regions of the world, women report that they want longer birth-spacing intervals than they are achieving; Few communications campaigns specifically promote the benefits of birth spacing; and There is great variability in the messages women get from their healthcare providers about the benefits of birth spacing. International health organizations involved in the Optimal Birth Spacing Initiative have found that birth spacing is a more acceptable way to promote family planning to women and their families, rather than advising them to have fewer children. This is especially true when working with traditional societies and youths. This is because messages about lengthening the time between births do not interfere with cultural norms that dictate the number of children wanted or the desire to prove fertility.

5 Documented Significant Evidences for Health Benefits
For Children Lower risk for: Stunted and underweight child Small for gestational age Low birth weight Preterm birth Child death Infant death Neonatal death Fetal death ABORTION (?) For Mothers Lower risk for: Malnutrition from overlap of pregnancy and breastfeeding Puerperal endometritis Premature rupture of membranes Anemia Third trimester bleeding Maternal death Here is a summary of the new research on the health benefits of birth spacing. These benefits are seen in children and their mothers. Children are at lower risk for: Stunting and being underweight, Being small for gestational age, Low birth weight, Preterm birth, and Death. This lowered risk includes mortality during childhood and infancy, as well as the neonatal and fetal periods. Mothers have a lower risk for: Malnutrition resulting from overlap of pregnancy and breastfeeding, Puerperal endometritis, Premature rupture of membranes, Anemia, Third trimester bleeding, and Maternal death.

6 Objective To assess risk of having short and prolonged interpregnacies intervals on the incidence of spontaneous abortion.

7 Research Methods

9 Sources of Data We used data from longitudinal surveillance at the DSS Purworejo site during the periods of where details of information regarding the spontaneous abortion and pregnancy status were collected. Details questions on pregnancy status was also confirmed by pregnancy test. We recorded pregnacies who were ends up with spontaneous abortion or live birth.

10 Sample for Analysis All Pregnants Women between cycles of Visitation 1-12: N=2510 Women Last Menstrual Period: 1/10/ /9/1997 n = 1958 Pregnancies with Complete Data on Abortions Determinants: n = 1910 First Pregnancies: n=567 Number of Pregnancies >2 Available for closed birth interval analysis: n=1343

11 Statistical Analysis A logistic regresion was used to estimate risk of interpregnancies interval on the incidence of spontanoues abortion. Adjustment to other risk factors, such as: age, parity, history of spontaneous abortion, previous used of contraceptives, and others social-economic variables.

17 Summary of the Findings
Six out of 100 pregnant women experienced spontaneous abortions annually. Risk of spontanoues abortion among interval of 1-12 months was 2.6 (95% CI: ) higher than months intervals, Having prolonged interpreganancies interval (85 months or more) was also higher (OR=3,6 with 95% CI: ) compared with months interval.

18 Summary of the Findings
After controling for others risk factors, the prolonged interpregancies interval continued to high risk of spontanoues abortion. After social-economic variables considered (results is not shown), histories of having previous used of contraceptives and spontanious abortion were also proven as risk factors for a spontaneous abortion.

19 Conclusion and Recommendation
Short and prolonged interpregnancies intervals were risk factors of spontaneous abortion Policy on the optimal birth spacing needs to consider an upper-limit for birth interval (not just over 3 years). This study suggests that interpregancies interval more than 4 years is increased risk of spontaneous abortion.
