THURSDAY, Nov. 10, 2022 (HealthDay News) — Exposure to air pollution during pregnancy is significantly associated with delays in neurodevelopment, according to a study published online Nov. 9 in Developmental Medicine & Child Neurology<\/em>.<\/p>\n Ping Shih, from the National Taiwan University Hospital in Taipei, and colleagues evaluated the association between ambient particulate matter \u00e2\u0089\u00a42.5 \u00ce\u00bcm in diameter (PM2.5<\/sub>) during the prenatal and postnatal periods and infant neurodevelopmental parameters. The analysis included 17,683 term singletons without congenital malformations.<\/p>\n The researchers found that PM2.5 <\/sub>during the second trimester was associated with increased risks for delays in gross motor neurodevelopmental milestones (adjusted odds ratio, 1.09 per 10 \u00ce\u00bcg\/m3<\/sup> increase in exposure to PM2.5<\/sub>). There were also associations of delayed fine motor development (adjusted odds ratio, 1.06) and personal-social skills with exposure to PM2.5<\/sub> in the second and third trimesters (adjusted odds ratios, 1.11 for the second trimester and 1.06 for the third). There were no associations observed between neurodevelopmental parameters and postnatal PM2.5 <\/sub>exposure.<\/p>\n “Protection of children from air pollutants needs to be started during their mothers pregnancy,” a coauthor said in a statement.<\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n <\/i><\/p>\n
