BACKGROUND Inhaling fine particles (particulate matter with diameter ≤ 2.5 μm; PM2.5) can induce oxidative stress and inflammation, and may contribute to onset of preterm labor and other adverse perinatal outcomes. [...] Key MethodMETHODS Long-term average (2001-2006) estimates of outdoor PM2.5 were assigned to 50-km-radius circular buffers around each health clinic where births occurred.Expand

Exposures to fine particulate matter (PM2.5) and birthweight in a rural‐urban, mother‐child cohort in Tamil Nadu, India
TLDR
The study provides some of the first quantitative effects estimates for linking rural‐urban PM2.5 exposures and birthweight in India, adding important evidence for this association from high exposure settings in LMICs, that also experience dual health burdens from ambient and household air pollution.
Critical windows for maternal fine particulate matter exposure and adverse birth outcomes: The Shanghai birth cohort study.
TLDR
G gestational exposure to PM2.5 was associated with adverse birth outcomes in infants, and critical windows were identified as 31st-34th gestational weeks for reduced birth weight, 38th-42 nd weeks for LBW and 27th-30th weeks for PTB, respectively.
Preterm birth associated with maternal fine particulate matter exposure: A global, regional and national assessment.
TLDR
The substantial percentage of preterm births estimated to be associated with anthropogenic PM2.5 (18% (13%-24%) of total pre term births globally) indicates that reduction of maternal PM2-5 exposure through emission reduction strategies should be considered alongside mitigation of other risk factors associated with preterm birth.
Combined effects of ambient air pollution and home environmental factors on low birth weight.
TLDR
Prenatal exposure to combined outdoor and indoor air pollution, particularly in critical window(s) during early pregnancy, significantly increases the risk of term LBW.
Maternal Exposure to Particulate Matter during Pregnancy and Adverse Birth Outcomes in the Republic of Korea
TLDR
PM10 exposure > 70 µg/m3 was associated with preterm births and low birth weight in term infants and further studies are needed to explore the pathophysiologic mechanisms and guide policy development to prevent future adverse effects on birth outcomes.
Exposure to coarse particulate matter during gestation and term low birthweight in California: Variation in exposure and risk across region and socioeconomic subgroup.
TLDR
Exposure to and risk from PM10-2.5 were heterogeneous across California indicating environmental justice implications and paternal characteristics were associated with the risk of TLBW even after controlling for maternal characteristics.
Intrauterine Inflammation and Maternal Exposure to Ambient PM2.5 during Preconception and Specific Periods of Pregnancy: The Boston Birth Cohort
TLDR
Despite relatively low exposures, the results suggest a monotonic positive relationship between PM2.5 exposure during preconception and pregnancy and IUI, and intrauterine inflammation may be a sensitive biomarker for assessing early biological effect of PM2-5 exposure on the developing fetus.
Geographic Variation in the Association between Ambient Fine Particulate Matter (PM2.5) and Term Low Birth Weight in the United States
TLDR
This study provided additional evidence on the associations between PM2.5 exposure during pregnancy and term LBW from a national perspective and identified significant positive associations in three census divisions of the United States: Middle Atlantic, East NorthCentral, and West North Central, and significant negative association in the Mountain division.
Associations of Pregnancy Outcomes and PM2.5 in a National Canadian Study
TLDR
This study provides further evidence linking PM2.5 and pregnancy outcomes with preterm birth, small for gestational age, and term birth weight, adjusting for individual covariates and neighborhood socioeconomic status (SES).
The relationship between air pollutants and maternal socioeconomic factors on preterm birth in California urban counties
TLDR
A retrospective study using geocoded birth certificate data, daily ambient air quality data on PM2.5 and O3, and American Community Survey data to assess census tract-level socioeconomic factors in California urban counties found a small positive association between maternal exposures to PM 2.5and O3 and preterm birth that varied by gestational exposure period.

Ambient Air Pollution and Low Birth Weight in Connecticut and Massachusetts
TLDR
Results indicate that exposure to air pollution, even at low levels, may increase risk of low birth weight, particularly for some segments of the population.
A Cohort Study of Traffic-Related Air Pollution Impacts on Birth Outcomes
Background Evidence suggests that air pollution exposure adversely affects pregnancy outcomes. Few studies have examined individual-level intraurban exposure contrasts. Objectives We evaluated the…
Maternal Exposure to Particulate Air Pollution and Term Birth Weight: A Multi-Country Evaluation of Effect and Heterogeneity
TLDR
Maternal exposure to particulate pollution was associated with LBW at term across study populations and three site characteristics and aspects of exposure assessment methodology appeared to contribute to the variation in associations reported by centers.
Traffic-related air pollution, preterm birth and term birth weight in the PIAMA birth cohort study.
TLDR
Maternal exposure to traffic-related air pollution during pregnancy was not associated with term birth weight and there was a tendency towards an increased risk of preterm birth with increasing air pollution exposure, but statistical power was low.
Association between ambient air pollution and birth weight in São Paulo, Brazil
TLDR
The results are consistent in revealing that exposure to air pollution during pregnancy may interfere with weight gain in the fetus, which is important from the public health perspective.
Ambient Air Pollution and Preterm Birth: A Time-series Analysis
TLDR
Limited support for late-pregnancy effects of ambient air pollution on preterm birth is provided by a retrospective cohort of 476,489 births occurring between 1994 and 2004 in 5 central counties of metropolitan Atlanta.
Relationships between air pollution and preterm birth in California.
TLDR
PM(2.5) and CO monitoring data from the California Air Resources Board were linked to California birth certificate data for singletons born in 1999-2000 and did not show differences by timing of exposure, although more detailed examination may be needed.
Ambient Carbon Monoxide and Fine Particulate Matter in Relation to Preeclampsia and Preterm Delivery in Western Washington State
TLDR
Predicted periconceptional CO exposure was significantly associated with preeclampsia after adjustment for maternal characteristics and season of conception, and further adjustment for year of conception essentially nullified the association.
Air Pollution and Birth Weight Among Term Infants in California
TLDR
An increased odds of SGA and a small difference in mean birth weight between infants with the highest and lowest exposures to PM2.5 are found and these findings have important implications for infant health because of the ubiquitous exposure to fine particulate air pollution across the United States.
