The key finding
A 2024 meta-analysis of 11 studies across Sub-Saharan Africa found that pregnancy intention is strongly associated with whether infants receive critical early-life care. Babies born to mothers who intended their pregnancies were 3 times more likely to receive essential newborn care (pooled odds ratio: 3.04), 2.2 times more likely to be exclusively breastfed (OR: 2.21), and 2.7 times more likely to be fully immunized (OR: 2.73) compared to those from unintended pregnancies. Even early breastfeeding initiation showed a 30% higher likelihood among intended pregnancies. These disparities occur within a region where newborn and infant mortality remain among the highest globally.
What the study looked like
Researchers systematically reviewed studies from four major health databases (MEDLINE, EMBASE, CINAHL, Global Health) focusing on Sub-Saharan African populations. From 235 identified articles, 11 met inclusion criteria for meta-analysis. The studies examined associations between mothers’ pregnancy intentions and completion of the “continuum of care” — a set of recommended practices including essential newborn care immediately after birth, early initiation of breastfeeding (within one hour), exclusive breastfeeding for six months, and full immunization schedules. The Newcastle-Ottawa Scale was used to assess study quality, and statistical tests measured heterogeneity across findings. All included studies were observational, comparing outcomes between mothers who reported their pregnancies as intended versus unintended.
Why researchers think this happened
The authors suggest that pregnancy intention may influence maternal preparedness, engagement with health services, and emotional readiness to provide consistent infant care. Women with intended pregnancies are more likely to attend antenatal care, plan for delivery, and seek postnatal follow-up — all of which increase exposure to health education about breastfeeding, immunization schedules, and newborn care practices. Conversely, unintended pregnancies may be accompanied by delayed care-seeking, reduced social support, or maternal stress that complicates adherence to recommended care practices. The review builds on prior research linking unintended pregnancy to adverse birth outcomes, extending the evidence to show that these disparities persist through the first year of life across multiple critical health behaviors.
How to read this carefully
This review combines observational studies, which cannot prove that pregnancy intention directly causes differences in care completion — only that the two are associated. Other unmeasured factors such as poverty, education, partner support, or healthcare access could explain part of the observed gap. The 11 included studies varied in design, sample size, and how they defined “unintended pregnancy,” which may have introduced inconsistency. Additionally, self-reported pregnancy intention can be influenced by recall bias or social desirability, and some women’s feelings about pregnancy may change over time. The findings represent patterns across diverse Sub-Saharan African contexts, so individual country circumstances may differ.
What this means for everyday life
For families and health workers in Sub-Saharan Africa, this research highlights that improving family planning access may have downstream benefits for infant health beyond preventing unwanted births. Women experiencing unintended pregnancies may benefit from targeted outreach to connect them with breastfeeding counseling, immunization reminders, and postnatal support. On a policy level, the findings suggest that strengthening voluntary family planning services could be one pathway to reducing the region’s high infant mortality rates — not only by reducing the number of unintended pregnancies, but by increasing the likelihood that every newborn receives the care needed to survive and thrive during the critical first months of life.
