Objectives: To analyze data from recent Demographic and Health Surveys (DHS) conducted in 21 low- and middle-income countries (LMICs) to examine patterns of interpregnancy intervals, unmet need, pregnancy risk and family planning method use and method mix among women 0-23 months postpartum.
Study design: Secondary analysis of postpartum women aged 15-49 years in 22 DHS surveys from 21 LMICs conducted between 2005 and 2012. We applied an adapted unmet need definition for postpartum women to look at prospective fertility preferences. We also constructed a new composite pregnancy risk indicator for postpartum women who have been sexually active since their last birth.
Results: In 9 of 22 surveys, 50% or more of nonfirst births occur at interpregnancy intervals that are too short. Overall prospective unmet need for family planning by postpartum women has not changed demonstrably since a 2001 analysis and is universally high: 61% of all postpartum women across the 21 countries have an unmet need for family planning. In 10 of 22 surveys, pregnancy risk rises steadily throughout the 2 years after birth. In the remaining 12 surveys, the risk of pregnancy peaks at 6-11 months after birth. Even when postpartum women are using family planning, they rely overwhelmingly on short-acting methods (51-96% in 21 of 22 surveys).
Conclusion: Our approach of estimating pregnancy risk by postpartum timing confirms a high probability for pregnancies to be less than optimally spaced within 2 years of a prior birth and suggests that special consideration is needed to effectively reach this population with the right messages and services.
Implications: Using recent, multicountry data for women within 2 years postpartum in LMICs, this paper updates existing estimates of high prospective unmet need for family planning and presents a new composite pregnancy risk analysis based on postpartum women's actual practices to demonstrate the magnitude of missed opportunities for programmatic intervention for the postpartum population.
