          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.

          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.
