The Impact of Extremes in Outdoor Temperature and Sunshine Exposure on Birth Weight

Following the “fetal origins of adult disease” hypothesis, environmental determinants of birth weight regained interest. The authors applied a detailed spatial-time exposure model for climatological factors thought to affect fetal growth: seasonality, temperature, and sunshine. Daily climatological data (29 stations) were linked to 1,460,401 term births with an individual exposure matrix for each pregnancy. Linear regression was utilized to determine effects of climatological factors on individual birth weight and existing spatial variations in birth weight.

Gender Differences in Respiratory Health of School Children Exposed to Rail Yard–Generated Air Pollution: The ENRRICH Study

Studies about environmental burdens often explore overall community risk. Increasing evidence suggests, however, differential burdens by gender and age. The purpose of the authors’ research was to determine if gender-related difference exists among children in a region plagued with poor air quality and if increased exposure to pollutants from a major goods movement rail yard influences the relationship. Using a cross-sectional study design, the authors provided respiratory screening for children at two elementary schools.
