Abstract
Background: Data on maternal characteristics that could predict antepartum fetal death in women receiving
antenatal care in resource-constrained settings are limited.
Aims: To identify maternal sociodemographic and clinical risk factors for antepartum fetal death among women
receiving antenatal care in a developing country setting.
Methods: Case-control analyses of risk factors in the occurrence of singleton fetal death before labour at two
university hospitals in south-west Nigeria over 4–5 years. A total of 46 cases and 184 controls were compared for
31 sociodemographic and clinical risk factors. Unconditional multivariate logistic regression analysis was applied to
determine independent risk factors. Level of significance was set at P < 0.05.
Results: The incidence of antepartum fetal death among women receiving antenatal care was 10.8 per 1000 total
births during the period. Significant risk factors at univariate level include proteinuria, pregnancy-induced
hypertension, pre-existing hypertension, reduced weight gain per week, previous antepartum fetal death, antepartum
haemorrhage, previous miscarriage, symphysiofundal height–gestational age disparity = 4 cm and perception of
reduced fetal movements. The independent risk factors were proteinuria (adjusted OR 4.23, CI: 1.57–11.42),
pregnancy-induced hypertension (adjusted OR 8.24, CI: 3.01–22.51) and perceived reduction in fetal movements
(adjusted OR 7.17, CI: 1.57–45.76).
Conclusions: The identified factors should serve as potential targets for antenatal interventions to prevent
antepartum fetal death in these institutions. Awareness of these factors should stimulate appropriate risk assessment
geared towards the prevention of antepartum fetal deaths by clinicians in these centres and centres in similar setting.
Key words: antenatal care, fetal death, Nigeria, stillbirth.
Introduction
Antepartum fetal demise constitutes an immense psychological
trauma to the expectant mother and may undermine her
confidence in orthodox pregnancy care, especially when the
attending clinician cannot provide a reasonable explanation.
Unlike in fetal deaths following intrapartum complications,
the factors responsible for prenatal fetal demise may not be
apparent to either the mother or her caregiver, and may
remain unexplained despite extensive investigations.

It is,
however, essential that the cause of death be determined
where possible as precise knowledge of the cause would serve
as the basis for counselling affected parents, prevention of
recurrence and treatment of previously undiagnosed medical
conditions. Unfortunately, only few centres in Nigeria have
adequate facilities to perform the recommended investigations
in cases of fetal deaths. Likewise, fetal autopsy that can
significantly increase the likelihood of discovering the presumed
cause,

is rarely performed because of scarce human and
material resources and strong cultural misconception.

Regardless of these limitations, it is the duty of obstetricians
practising in resource-constrained settings to devise means
of limiting antepartum stillbirths, especially among patients
who receive antenatal care. While most reports on perinatal
