With respect to the exposure setting (home vs. school), assuming fixed effects, the OR was 1.03 (95% CI, 1.02 1.04) for home exposure, whereas for school exposure the OR was 1.32 (95% CI, 1.05 1.66).
We used publicly available records about the geographic positions of schools (North Carolina Center for Geographic Center and Analysis 2002) and swine CAFOs (Wing et al. 2000, 2002) to generate location-based estimates of in-school exposure for each school.
The team will get to play on national TV, on ESPNU, which is great exposure for a school that most people still call Towson State.
The agency's exposure limits for schools under those health guidelines are levels at which concentrations of PCBs in the indoor air are considered unlikely to cause harm.
Also, accounting for exposure at school did not influence the observed air pollution health effect estimates that we based on home exposures alone.
Our estimates of near-roadway effects also did not account for exposure at school and other locations beside the home, which recent studies suggest may also cause asthma (McConnell et al. 2010).
The HR for exposure at schools was almost as large as for residential exposure (HR = 1.45; 95% CI, 1.06 1.98), and the combined average exposure weighted for time at school and home had a slightly stronger association (HR = 1.61; 95% CI, 1.29 2.00).
At the age of 14, speaking only Creek and Miccosukee, Betty swapped her patchwork dress for the clothing of whites, and she, her brother and cousin headed to North Carolina for their first exposure to school.
The adjusted data were used to approximate population coverage for school-year cohorts (born from October 1 through September 30 of the following year) to allow for similar levels of exposure within school years.
The increased prevalence in children (13 ) may be due to the enhanced opportunity for exposure at schools and daycare centers.
