ABSTRACT
This study investigated congenital anomalies in
a tertiary healthcare institution in Rivers State,
Nigeria. The objectives of the study were to
determine the prevalence and patterns of
congenital anomalies in the hospital. The study
adopted descriptive retrospective design. The
study population included cases of congenital
anomalies record in the tertiary healthcare
institution from January 2015 to January 2019
which totaled 3171 out of which a sample of 203
was selected using the purposive sampling
technique. The instrument for data collection
was the researcher (self) structured checklist
with a reliability index of 0.77. Data analysis
was done using descriptive statistics of
frequencies and percentages. Results revealed
that the prevalence of congenital anomalies in
the tertiary healthcare institution from January
2015 to January 2019 was 6%; maternal parity,
type of gestation, self medication and use of
herbal medication were significantly associated
with congenital anomalies; the types of
congenital anomalies diagnosed include
myelomeningocele (4%), hydrocephalus (2.5%),
neural tube effect (2%), ventricular septal defect
(4%), atrial septal defect (2%), patent ductus
arteriosus (2%), ventriculomegaly (1%),
unspecified heart disease (2%), oesophageal
atresia (3%), malrotation (4%), hirchsprung’s
disease (3%), cleft lip and palate (5%), eye
anomaly (4.4%), urinary/genital (6.4%),
omphalocele (4%), skeletal (6%), talipes
equinovarus (7%), polydactyly (4.4%), inguinal
hernia (5%), umbilical hernia (9.4%),
laryngomalacia (4.4%), down syndrome (3.4%),
undescended testes(2%), microcephaly (3.4%),
spinal bifida (3.4%) and microphthalmia
(3.4%); the variables of sex, gestational age at
birth, mode of delivery, obstetric complication,
birth weight, asphyxia and maternal age did not
significantly influence the prevalence of
congenital anomalies in neonates. The study
concluded that there is an increasing prevalence
of congenital anomalies in neonates. Based on
the study findings, the need for healthcare
providers including Midwives to provide
mothers and the general public with
information on the causes and preventive
strategies for congenital anomalies was
recommended.

INTRODUCTION
A congenital anomaly is a condition
present at birth irrespective of the cause [1].
According to the World Health Organization,
congenital anomalies can be defined as structural or
functional abnormalities, including metabolic
issues, which are present at the time of birth [2, 3].
Congenital abnormalities may result from
distortion of the typical chromosomal composition
as well as impedance of normal development in the
uterus by factors such as drugs, alcohol, viral and
bacterial infections as well as by ionizing radiations
[4]. However, the etiology of most congenital
anomalies is multifactorial [5]. Congenital
anomalies are a significant part of the worldwide
burden of health problem among children
representing 25 million disability adjusted life
years around the world [6]. Congenital
malformations may present as either single isolated
defect or as different organ framework
abnormalities in an individual.
The prevalence of congenital anomalies changes
from nation to nation. It is accepted that between 2-
4% of the live conceived babies and 15-20% of
stillbirths have huge birth deformities [7].
Malformations at birth are a significant reason for
childhood illnesses and mortality as it is
approximated that one out of each 3 infants that
dies has a congenital disorder [8]. The World
Health Organization (WHO) appraises that nearly
260,000 deaths around the world (about 7% of
every single neonatal death) were brought about by
congenital anomalies in the year 2004. [3] In the
United States, they happen in about 3% of babies.
They resulted in about 628,000 deaths in 2015,
down from 751,000 of every 1990 [2]. The sorts
with the greatest number of deaths are heart disease
(303,000), followed by neural tube defect (65,000)
[1].
