Abstract

BackgroundFertility intentions and contraceptive use are often used to demonstrate gaps in programs and policies to meet the contraceptive needs of women and couples. Prior work demonstrated that fertility intentions are fluid and change over a woman’s (or couple’s) life course with changing marital status, childbearing, and education/employment opportunities. This study uses longitudinal data to better examine the fluidity of women’s fertility intentions and disentangle the complex interrelationships between fertility and contraceptive use.MethodsUsing survey data from three time points and three urban sites in Senegal, this study examines how women’s fertility intentions and contraceptive use in an earlier period affect pregnancy experience and the intentionality of experienced pregnancies among a sample of 1050 women who were in union at all three time points. We apply correlated random effect longitudinal regression methods to predict a subsequent birth by fertility intentions and modern contraceptive use at an earlier period addressing endogeneity concerns of earlier analyses that only include two time periods.ResultsDescriptive results demonstrate some change in fertility desires over time such that 6–8% of women who reported their pregnancy as intended (i.e., wanted to get pregnant at time of pregnancy) reported earlier that they did not want any(more) children. Multivariate analyses demonstrate that women who want to delay or avoid a pregnancy and are using modern contraception are the least likely to get pregnant. Among women who became pregnant, the only factor differentiating whether the pregnancy is reported as intended or unintended (mistimed or unwanted) was prior fertility intention. Women who wanted to delay a pregnancy previously were more likely to report the pregnancy as unintended compared to women who wanted to get pregnant soon.ConclusionsThese results suggest some post-hoc rationalization among women who are getting pregnant. Women who say they do not want to get pregnant may be choosing not to use a contraceptive method in this urban Senegal context of high fertility. Programs seeking to reach these women need to consider their complex situations including their fertility intentions, family planning use, and the community norms within which they are reporting these intentions and behaviors.

Fertility intentions and contraceptive use are often used to demonstrate gaps in programs and policies to meet the contraceptive needs of women and couples

Longitudinal data were collected from a representative sample of women of reproductive age (15–49 years) in six urban sites of Senegal using a two-stage sampling design. (The sites were selected by the implementing partners and the donor prior to baseline data collection.) For the 2011 baseline sample selection, in the first stage we used census districts as primary sampling units (PSUs) and randomly selected PSUs from each study city

Summary

Introduction

Fertility intentions and contraceptive use are often used to demonstrate gaps in programs and policies to meet the contraceptive needs of women and couples. In 2012, an estimated 85 million unintended pregnancies occurred worldwide [1]. The highest regional rate of unintended pregnancy among women ages 15–44 years occurred in Africa (80 unintended pregnancies/1000 women) [1]. Within Africa, the highest sub-regional rate was 108 unintended pregnancies per 1000 women in both Eastern and Middle Africa [1]. Recent modeling of unintended pregnancy rates globally demonstrates declines in unintended pregnancy rates over time; the amount of change was smaller in developing as compared to developed countries [2]. Unintended pregnancy is a global concern since women who experience an unintended pregnancy may resort to unsafe abortion and unintended pregnancy may be a cause or consequence of socioeconomic inequities [2]
