Few studies have examined associati

Few studies have examined associations of birth outcomes with toxic air pollutants (air toxics) in traffic exhaust.
This study included 8,181 term low birth weight (LBW) children and 370,922 term normal-weight children born
between January 1, 1995, and December 31, 2006, to women residing within 5 miles (8 km) of an air toxics
monitoring station in Los Angeles County, California. Additionally, land-use-based regression (LUR)-modeled estimates
of levels of nitric oxide, nitrogen dioxide, and nitrogen oxides were used to assess the influence of small-area
variations in traffic pollution. The authors examined associations with term LBW (37 weeks’ completed gestation
and birth weight

Few studies have examined associations of birth outcomes with toxic air pollutants (air toxics) in traffic exhaust.This study included 8,181 term low birth weight (LBW) children and 370,922 term normal-weight children bornbetween January 1, 1995, and December 31, 2006, to women residing within 5 miles (8 km) of an air toxicsmonitoring station in Los Angeles County, California. Additionally, land-use-based regression (LUR)-modeled estimatesof levels of nitric oxide, nitrogen dioxide, and nitrogen oxides were used to assess the influence of small-areavariations in traffic pollution. The authors examined associations with term LBW (37 weeks’ completed gestationand birth weight <2,500 g) using logistic regression adjusted for maternal age, race/ethnicity, education, parity,infant gestational age, and gestational age squared. Odds of term LBW increased 2%–5% (95% confidenceintervals ranged from 1.00 to 1.09) per interquartile-range increase in LUR-modeled estimates and monitoringbasedair toxics exposure estimates in the entire pregnancy, the third trimester, and the last month of pregnancy.Models stratified by monitoring station (to investigate air toxics associations based solely on temporal variations)resulted in 2%–5% increased odds per interquartile-range increase in third-trimester benzene, toluene, ethylbenzene, and xylene exposures, with some confidence intervals containing the null value. This analysis highlightsthe importance of both spatial and temporal contributions to air pollution in epidemiologic birth outcome studies.air pollution; benzene; fetal growth retardation; hydrocarbons, aromatic; infant, low birth weight; pregnancy

Beberapa studi telah meneliti hubungan dari hasil kelahiran dengan polutan udara beracun (racun udara) dalam lalu lintas knalpot.
Penelitian ini termasuk berat badan lahir rendah anak 8181 istilah (BBLR) dan anak-anak dengan berat badan normal 370.922 jangka lahir
antara 1 Januari 1995, dan 31 Desember, 2006, perempuan yang berada dalam jarak 5 mil (8 km) dari racun udara
stasiun pemantauan di Los Angeles County, California. Selain itu, regresi penggunaan lahan berbasis (LUR) -modeled perkiraan
tingkat oksida nitrat, nitrogen dioksida, dan nitrogen oksida digunakan untuk menilai pengaruh kecil-daerah
variasi dalam polusi lalu lintas. Para penulis meneliti hubungan dengan BBLR jangka (? 37 minggu kehamilan selesai
dan berat lahir <2.500 g) menggunakan regresi logistik disesuaikan dengan usia ibu, ras / etnis, pendidikan, paritas,
usia kehamilan bayi, dan usia kehamilan kuadrat. Odds istilah BBLR meningkat 2% -5% (kepercayaan 95%
interval berkisar 1,00-1,09) per kenaikan interkuartil-range perkiraan LUR-model dan monitoringbased
racun udara perkiraan eksposur di seluruh kehamilan, trimester ketiga, dan bulan lalu kehamilan.
Model dikelompokkan berdasarkan stasiun pemantauan (menyelidiki asosiasi racun udara hanya berdasarkan variasi sementara)
mengakibatkan 2% -5% meningkat kemungkinan peningkatan per interkuartil-range di ketiga trimester benzena, toluena, etil
benzena, dan xilena eksposur, dengan beberapa interval kepercayaan yang berisi nilai null. Analisis ini menyoroti
pentingnya kedua kontribusi spasial dan temporal untuk polusi udara dalam studi epidemiologi hasil kelahiran.
