Abstract
A growing body of
literature has documented the adverse effects of bisphenol A (BPA) exposure on
pregnancy and birth outcomes. Regardless, how gestational BPA exposure affects
mother-newborn pairs in Malaysia is yet to be explored. Hence, this study aimed
to investigate urinary BPA levels of pregnant women living in Klang Valley and
their associations with adverse obstetric and birth outcomes. This
cross-sectional study involved pregnant women in their third trimester
attending antenatal clinic in Hospital Al Sultan Abdullah (HASA), UiTM Puncak Alam, who planned to have their delivery in HASA.
Information on maternal age, parity, education, household income, gestational
age, and obstetric complications, such as Gestational Diabetes Mellitus (GDM),
preeclampsia, preterm labour, and foetal growth restriction (FGR) were
collected. Maternal urine samples were also obtained and evaluated using liquid
chromatography-tandem mass spectrometry (LC-MS/MS). Additionally, the neonatal
outcomes including mode of delivery, gestational age, birth weight and need for
NICU admission were documented. Our LC-MS/MS analysis showed that BPA was
present in all the urine samples, with levels varying from 4.42 to 30.86 ng/mL. The median level was 15.96 ng/mL. Urinary BPA level
has no significant correlation with gestational hypertension (GHTN), preterm
labour and low birth weight babies. Babies who need NICU admission were born to
mothers who exhibited significantly different urinary BPA levels compared to
those whose babies were not admitted (p=0.049). Finding from this study suggestive of further investigation
on level of gestational urinary BPA with NICU admission, ideally with a larger
sample size to validate these results.

Abstrak
Badan kepustakaanyang semakin meningkat telah mendokumentasikan
kesan buruk bisfenol A (BPA) terhadap kehamilan dan kelahiran. Namun begitu,
bagaimana pendedahan BPA semasa kehamilan memberi kesan terhadap pasangan ibu
dan bayi baru lahir di Malaysia masih belum diterokai. Oleh itu, penyelidikan
ini bertujuan untuk mengkaji tahap BPA dalam air kencing wanita hamil yang
tinggal di Lembah Klang dan kaitannya dengan kesan buruk obstetrik dan
kelahiran. Kajian keratan rentas ini melibatkan wanita hamil dalam trimester
ketiga yang menghadiri klinik antenatal di Hospital Al Sultan Abdullah (HASA),
UiTM Puncak Alam, yang merancang untuk bersalin di HASA. Maklumat mengenai umur
ibu, pariti, pendidikan, pendapatan isi rumah, usia kehamilan dan komplikasi
obstetrik, seperti Gestational Diabetes Mellitus (GDM), preeklampsia, kelahiran
pramatang dan sekatan pertumbuhan janin (FGR) telah dikumpulkan. Sampel air
kencing pesakit juga diambil dan dianalisis menggunakan kromatografi cecair
spektrometri jisim tandem (LC-MS/MS). Di samping itu, hasil neonatal termasuk
cara melahirkan, umur kehamilan, berat bayi ketika lahir dan keperluan untuk kemasukan NICU telah didokumenkan. Semua sampel air kencing didapati mengandungi BPA dan parasnya adalah antara 4.42 hingga 30.86 ng/mL. Tahap median ialah 15.96 ng/mL. Tahap BPA kencing tidak mempunyai korelasi yang signifikan dengan hipertensi semasa hamil (GHTN), kelahiran pramatang dan berat lahir bayi yang rendah. Bayi yang memerlukan kemasukan NICU dilahirkan oleh ibu yang menunjukkan tahap BPA kencing yang berbeza
secara ketara berbanding mereka yang bayinya tidak dimasukkan (p = 0.049).
Penemuan daripada kajian ini mencadangkan kajian lanjut mengenai tahap BPA
dalam air kencing semasa kehamilan dengan kemasukan NICU, idealnya dengan saiz
sampel yang lebih besar untuk mengesahkan keputusan ini.
