Abstract:
Introduction In 2015, almost half of low birth weight babies in the world were born in
Southern Asia. It is contributed by multiple factors including maternal
exposure to the elements in the environment during the antenatal period.
Particulate matter (PM10) pollution in Southeast Asian region have been
extensively studied with known attributions and sources. It is also known that
PM10 is able to restrict foetal growth at molecular level. This review intends
to investigate if the unborn in Asia are affected by air pollutants indirectly
through their mothers.
Methods Publications from Scopus and Science Direct digital databases in Asian region
from 2015 onwards were reviewed. Details collected were the year of
publication and study location, the study design, investigated air pollutants,
exposure estimation methods used, the timing of exposure in relation to
pregnancy, pregnancy outcome measured and the relative risk or odds of effect.
Results A total of eight full text articles were included. Most of the studies were of
cohort and quasi experimental designs, involving local air monitoring
measurements to assign exposure.
Conclusions There were more studies considered multiple air pollutants as contributing risk
rather than a single pollutant. The exposure was measured according to stages
of pregnancy and the trimester stratification is the most often method used.
Modalities used in representing birth outcomes were not confined to birth
weight alone but also included the length of gestation. Exposure to PM10 have
been found to be associated with reduction in birth weight and increased risk
for preterm birth in Asia.
