Pregnancy risks and contraceptive use among postpartum mothers in Cameroon: implications for improving the coverage of postpartum family planning services

Background The health hazards of short inter-birth intervals are severe in Cameroon. One-quarter of inter-birth intervals are less than 24 months and the probability of death before age 5 for children born after a short interval is double that associated with intervals of 36–47 months. We examine the risk of an unintended pregnancy in the 18 months following childbirth in Cameroon, taking into account the protective effects of lactational amenorrhea, delayed resumption of sex as well as contraceptive use. Methods Data from 3007 postpartum women in the nationally representative 2018 Cameroon Demographic and Health Survey were used. Risk of an unintended pregnancy was defined from current status information on resumption of sex and menses, contraceptive use, desire for another child within 12 months, and, for the minority of pregnant women, whether the conception was intended. Predictors of risk, and of modern method use, were assessed by bivariate and multivariate analysis. Results In the first 6 postpartum months, only 8% of women were fully at risk (i.e., sex and menses resumed but no contraceptive use), rising to 24% at 6–11 postpartum months, and further to 30% at months 12–17. Though 89% wanted to delay the next birth by at least 1 year, only 17% were currently using a modern method. Menstruating women were much more likely to be users than amenorrheic women: 27% versus 15% at months 12–17 postpartum. Urban and better educated women recorded higher contraceptive use but lower protection from other factors than rural, less educated women, with the net result that risk differed little across these population strata. Uptake of maternal and child health (MCH) services was high but only one-third of women had discussed family planning at a facility visit during the preceding 12 months. Conclusions These results underscore the need for improved postpartum family planning services by means of closer integration with mainstream health services. In view of evidence from other sources of heavy workload and weak motivation of health staff, this will require strong leadership. A related priority is to increase the number of staff trained in provision of long-acting methods, such as implants.
