Introduction
� Historically, postpartum women in the developing world relied on traditional birth spacing methods ØLactational amenorrhea & ØPostpartum sexual abstinenceØLong breastfeeding durations
� Today there is reduced role of traditional birth spacing mechanisms due toØ Introduction of modern contraceptives, ØCultural transformations, Ø Increasing urbanization

Why study postpartum women?
� Nearly one third of women in SSAØexposed to the risk of pregnancy (sex + no contraceptives) within 2
years of childbirth.
� Short birth intervals and unwanted pregnancies Ø Decrease survival chances for the born baby Ø Present worse health outcomes for motherØ Unwanted pregnancies - increasing abortion
�Challenges of unmet need Ø Highest in the first year of the postpartum period (Ross and Winfrey 2001)
Ø High among poor and less educated women (Ashford 2003; Westoff 2006)

Why RH needs for urban poor?
�Urban populations projections ØAnnual growth rate of 2.4% (UN-HABITAT 2008).
ØLeading to rising poverty, inadequate shelter; access to safe water, sanitation, education and health services.
Ø Increasing urban populations means future population growth depends on the RH policies adopted for urban areas today.
ØUnderstanding the RH needs of urban poor contributes to MDGs on maternal and child health.
ØMapping timing of the initiation of postpartum FP is essential in designing better FP programs for urban poor.

Example: Kenya urban slums
Ø characterized by congestion, disease, crime, poor hygiene, violence, poverty, early sexual debut, etc.
Ø Slum TFR is 4.0 (2000) vs 4.9 (Kenya national 2003)
Ø Slum maternal mortality ratio=706 per 100,000 live births.
Ø Slum HIV prevalence is 11.5 vs 7-8%(National 2007 )
E.g. Kenya, rising urbanization is reflected in the many informal settlements that house over 50% of the Nairobi city population.

Data and Methods
� Eligibility criteria� birth since September 2006 (last 12 months).� Births in study area (2 Nairobi slums).
�Open-cohort � Follow-up interviews conducted every 4months thereafter.
� A monthly calendar type questionnaire used� Administered retrospectively to cover period since birth to interview� Data on sexual behaviour, menstrual resumption, breastfeeding

Choice of first contraceptives & timing of menstruating among women in informal settlements.
*FP=Family planning
� Injectables (12 monthly average of 48%) and pills (22%) remain the most common methods used during the 1st 12 months.
� Condom use is low

Key results� Sexual resumption seems to occur earlier thanØmenses resumptionØpostpartum contraceptive resumption.
� Menses resumption acts as a trigger for initiating postpartum contraceptive useØheightened peak of first contraceptive use occurs shortly after the
first menses.
� Minimal differences in contraceptive method choice are observedØbetween early adopters vs late adopters in respect of menstrual
resumption.
� Few women use condoms, Øa method for dual protection against STI /HIV and pregnancy.
� For months where women were exposed to the risk of pregnancy (resumed sexual relations and menses)Øabout 28% were months where no contraceptive method was
used.

Conclusions� Contraceptive use high, adoption of FP is early but there a few
who face the risk of pregnancy
� Condom use is low – expected if compared to national averages
� Postpartum poor women need increased access to family planning and reproductive health services Ø in order to reduce the numbers of unwanted births, abortionsØ increase the length of subsequent birth intervals and better maternal health
outcomes.
� Postnatal visits and other subsequent health system contacts arepromising opportunities for serving postpartum women with a desire to use family planning services in Nairobi urban slums.
