Ratio of means, obtained by back-transforming the estimated change in Loge (BMI) corresponding to the SES change specified; P - Value for test of linear trend in Loge (BMI); €Block group estimate from the 2010 Census tract-level; *Includes additional adjustment for acculturation (language spoken most of the time): English, Spanish; IQR Interquartile range. IQR of area - level SES measures are estimated based on 142 block groups within the sampling area.
