Women’s Responses to Survey Questions on Contraceptive Use May Overestimate Actual Protection from Unintended Pregnancy

International Perspectives on Sexual and Reproductive Health. Volume 41, Number 3, September 2015
In settings where inconsistent, long-term use of the injectable and other short-term methods is common, the contraceptive prevalence rate calculated from responses to questions in cross-sectional surveys may overestimate the proportion of women protected against unintended pregnancy, according to “Contraceptive Dynamics in Rural Northern Malawi: A Prospective Longitudinal Study,” by Aisha Dasgupta et al., of the London School of Hygiene and Tropical Medicine. Contraceptive service data from a one-year prospective study in Karonga, a demographic surveillance site, indicated that only 51% of injectable users received their first reinjection on time, and just 15% received all their reinjections on time during the 12-month study period. In addition, the proportion of women in Karonga using the injectable at seven months after uptake, as estimated from service data (14%), was considerably lower than the proportion estimated from cross-sectional data from the Malawi Demographic and Health Survey (20%), suggesting that the former estimate picked up discontinuation and gaps in coverage not captured by women’s responses to questions about contraceptive use in the survey.
